The technical field

This invention relates to electrical engineering, in particular to the light sources to control devices with colored light streams.

Prior art

The currently proposed decorative lamps, based on traditional light sources and LEDs are very diverse in appearance, but their aesthetic and emotional impact on the person not always taken into account. Often they are not attractive. With the exception of copies made as works of art.

Significant improvement of the parameters of light-emitting diodes, in recent times, and ease of management are allowed to embark on their advantages in those areas where it was previously limited their low lighting performance. On the basis of currently created and produced samples of lighting fixtures and lamps (see, for example, U.S. patent No. 6257737 [1]international application WO 01/24583 [2]). In accordance with [1] generates white light with static mixing red, green, and blue radiation of the LEDs without the use of any device for dynamic management of radiation. This mixture should be precise and homogeneous not only in range and power, but in the space h which is achieved by the use of the required control devices emission of LEDs of different colors.

Known decorative lamp comprising a glass envelope, at least two LEDs of different colors are located inside the shell and base, established in accordance with this lamp that contains a system of electrodes for connecting the lamps to the power supply network on the one hand and LEDs on the other. Thus heads of LEDs fabricated so that their radiation is spread on all sides except the base (see patent EP 0822371 [3]). Its disadvantages include the used device control not allowing you to create color effects, which leads to its lack of appeal.

In U.S. patent No. 6183086 [4] described ophthalmologic device with adjustable multi-color led light system. The device is intended for medical purposes, in particular the impact on the patient's eye radiation of a fixed wavelength, the resulting regulation used by the control device, which provides only a static mixing radiation of LEDs of different colors.

Obviously, leave the best impression and therefore more attractive lamps with variable time light color, which are thus much more decorative.

The closest the present invention is a decorative the multicolor lamp with a control device (see international application WO 01/41514 [5]), is placed into an external enclosure, hermetically sealed for use in swimming pools. The radiation source mentioned lamp consists of LEDs of three colors, which are localized in three solid color groups, and a control unit to the controller. The group posted on the Board and the illumination of each single-color led group of spatially separated. The power supply takes place via the control device with a controller that contains the programmed channels for separate control of the emission of the LEDs of each color, i.e. for separate control single color groups. Each monochrome group serves rectangular repetitive pulses of power with a predetermined repetition period of the pulse, the duration of his front rise, decline and pause. For a given program [5] provided by the equality of the durations of the periods of repetition of the pulses. In addition, the initial phase of the pulses of power to the first radiating color with respect to the second radiant color different from the initial phases for the second emitting color with respect to the third radiant color on the same multiple of the value. This program provides only sequential on-off monochrome groups of LEDs to create a consistent spark is of spatially dispersed three colors.

The radiation source is mounted on the flat base of the inner housing of the known lamp. On one side of the base is placed on the card with the groups of LEDs, and on the other side of the control device with the controller. The diffuser cap inner casing through which passes radiation of LEDs, mounted in the walls of the inner casing, which, in turn, is fixed on the base, the location of the LEDs. Conclusions the power control device is placed and mounted outside of the lens. The lens is a transparent plate, the surface of which is marked grooves (embossing) to obtain a more uniform and aesthetically pleasing glow of LEDs of each color group. In this known lamp [5] provided a series connection of LEDs of different colors and there is no mixing of the radiation in the form of available designs. Such a lamp [5] does not produce a strong emotional impact, it is not enough aesthetic and attractive.

Disclosure of inventions

The technical result of the present invention is to improve the aesthetic and emotional perception, an approximation to the optimality of the psychophysiological effects of decorative multicolor lamp with mean is Ino extended gamut color effects, leading to fascinating effect, increase its attractiveness, efficiency, and expanding its functionality and add new properties, reduction and simplification of its operation.

The technical result is achieved by the fact that the decorative multi-color lamp control device, comprising a radiation source containing at least two LEDs of different colors with the specified spatial distributions of radiation and placed with a given spatial localization, cost and control device containing programmable channels for separate control of the emission of the LEDs of each color by filing a periodically recurring pulses of power with a predetermined repetition period of the pulse power, duration of its front rise, decline and pause for LEDs of each color, and also includes a diffuser, and the LEDs of different colors are spatially localized in at least one group, the control device is made providing management of radiation of the LEDs so that the length of the front rise and fall of each pulse is in the range from not less than 1 sec to 300 sec, the duration of the periods are in the range of from not less than 2 seconds to 600 seconds and the LEDs once the CSOs color duration periods are independent of each other, and duration of pauses is not more than 2/3 the duration of the relevant period, the diffuser is made surrounding at least partially the incidence of radiation of the led radiation source, and Board with LEDs placed inside of the lens.

The difference decorative multicolor lamp ("Lamp") is the original set of essential distinguishing features, consisting of non-obviousness due to the layout of the materials (and their characteristics), made from the elements, and with the original control emission of the LEDs. The choice of this combination has allowed manufacturing Fixtures for a wide variety of purposes, highly reliable, optimal psychophysiological effects, much better aesthetic and emotional perception, cheap, new, simple in design and relatively cheap.

Note that the next group of LEDs (spatially localized LEDs of different colors) will be called a "cluster". One programmed channel control device is designed to control the LEDs of the same color, in the simplest case, at least one cluster, by filing a periodically recurring pulses of power. The number of such channels for each is the laster radiation source is determined at least by the number of incoming in a variety of colors, which emit lights.

To control the LEDs of all colors in a specific cluster is the full combination of all of these channels. However, one combination of channels can be used not only to manage a single cluster, but any number of clusters included in the radiation source. Then they all change color at the same time in accordance with the selected program for each color. In addition, when the corresponding need no restrictions on the use of the above combination of channels for managing clusters with more than one radiation source. In the General case, different combinations of channels may be several depending on the purpose and configuration of the Lamp as a source of radiation, and for several in one Lamp.

The proposed Lamp can be implemented in various modifications, its elements can also be quite different shapes, made of different materials, etc. and they will all be linked to a single common purpose.

Offered a wide range of different modifications of the Lamp causes a different number of considered elements of the Lamp.

For example, the technical result is achieved by the fact that:

the proposed Lamp is provided in addition at least one light source is kOhm radiation

the radiation source is further provided with at least one device management

the radiation source is further provided with at least one card, the specified number located on your card, depending on the configuration and number of elements of the lens, the number of clusters, LEDs in the cluster, the number of control devices and their locations, and so on,

- on Board may(may) be located(s) cluster(s) and/or device(s) control,

- on Board may(may) be sited(s) device(s) management and Board can be placed inside of the lens or outside of the lens (the location is outside of the diffuser including allows you to simplify operation of the Lamp is simplified device management and change),

- all controls are located on the same Board,

each control device is located on the Board,

the diffuser can be located on the ground,

the base can be made or monolithic or composite,

- card or card placed inside of the lens, may(may) be located(s) based on, and directly on the inner part of the lens, or in some other way fixed(s) inside of the lens.

A different number of individual elements CBE is ilnicka can be used in almost all modifications, described next. The mutual location of existing and additional elements depends on the specific design of the Lamp in relation to its purpose.

Note that we introduced in the region of tastes, feelings, emotions, perceptions, etc. where the numerical values are determined on the basis of intuition and feelings, which, of course, can be quite different for different people. Specific boundary values of parameters of pulse power LEDs of different colors we selected on the basis of statistical processing of intuitive assessments of different people, which may differ from person to person. However, observations and experiments allow to conclude that these judgments are justified.

The duration of the repetition period of the pulse power is the sum of the durations of the elements of the pulse (rise front of repetitive impulse, peak, recession repetitive pulse) and pause, which corresponds to a total time of a complete and repetitive sequence of changes in the intensity of the LEDs of any color.

In addition, we will agree that if the duration of the periods and elements of pulse power and pauses for LEDs of different colors specific source is equal for all LEDs of a specific source, such pulse power (and periods) are defined the same as, but independent from each other - the initial phase of feeding these pulses do not coincide (shifted pulses and periods). Accordingly, the program, which feeds these pulses will be called the same. Option when the initial phase of the pulses of power are the same, is possible, but it is obvious and uninteresting, because in this case there is a simple ripple source with colors close to the middle of the color chart, i.e. to the white color. In the future, this option is not considered.

If the duration of the periods and items respectively pulse power and pauses for LEDs of different colors a particular source are different from each other, such that the pulses of power (and periods) is defined as unequal pulses (periods). Accordingly, the program, which feeds these pulses will be called differently.

The effect of almost continuous change the color of the source is almost independent from the shape of the cyclogram of the power change. To achieve a technical result it is necessary to change the pulse power from minimum to maximum and back was rather monotonous. Therefore, we choose between two extremes - from almost rectangular trapezoidal until smooth curve containing no sections with constant values is, i.e. having a character similar to a sine wave.

The observation of pure colors or transitions between the three pairs of these colors is possible, if there are periods when one of them either do not Shine at all, or its intensity is negligible. Accordingly, the best effect is observed when the other one or two colors are close to their maximum values. Since getting clean colors is not the main aim of the proposal, the conditions of their occurrence here is not considered in depth.

We have created a Lamp that is monotonically and continuously changes the color of the glow. This is due to the fact that the change of the intensities of the LEDs of different colors occurs in accordance with mismatched between periodic patterns of at least one of the parameters.

It seems that for an observer it is a smooth change in intensity and, accordingly, the color tone is pleasant and not irritating, i.e. if it is not "instantly", as in the known lamp [5], and for a relatively long time period.

Of course, the minimum length front rise or decline pulse power (or intensity) of the LEDs of a specific color selected from 1 sec, somewhat arbitrary, but nevertheless close to the truth, because the ku only during this or the more time the effect becomes noticeable and attractive. When this is supplied periodically recurring pulse power, with intermediate forms from the well-known rectangular shape, but not including, to sinusoidal, including her. Smaller times (less than 1 sec) enable or disable one or the other color of the source seem to be "instant" and correspond to the rectangular shape of the repetitive pulse power (see [5]).

Experimentally obtained minimum time period of 2 seconds, in which frequent blinking goes conventionally not irritating smooth ripple.

We found that when the duration of the period more than 10 minutes or 600 seconds the lamp will appear to be just almost monotone and uninteresting, because it will be too slow color change that acts Atalaya and does not attract the attention of ordinary people. Of course, the upper limit of the period it was more difficult to assess, since it is largely determined by the individuality of the observer.

Empirically derived maximum length front rise and fall of the pulse power supply is 300 sec for the case when the maximum duration of a complete period is 600 seconds, and the duration of the peaks and pauses minimum. Almost the entire period consists only of UPS and downs, and the shape change of the voltage across the tsya sinusoidal form.

If there is the illumination of all three colors simultaneously, albeit with variable intensity, it is difficult to expect as pure colors and eye-catching transitional shades between them. At zero or close to it time consuming pauses the trajectory of change will be inside the chart color near the Central point white. This change also may be used. To increase the likelihood of getting in the peripheral part of the diagram the duration of the pauses of any one color should be increased. Thus given the opportunity to" Shine other colors: any two at the same time, or even one color. The duration of the pauses can be very different, ranging from the minimum to the maximum, but not more than 2/3 of the duration of the relevant period because of greater duration are often observed noticeable "failures" of the glow lamp and thereby reduces its attractiveness, efficiency. Thus, in General, the proposed program provides a sequence of intensities of LEDs of different colors, using the pause allows the "coverage" of the entire color chart, including its external border (perimeter).

Independence and, consequently, the diversity of the durations of the cycles of pulses for LEDs of different color is one avoids appreciable frequency changes in colour during operation of the lamp and thereby improve its decorative effect. However, this does not preclude the use of and equal pulse durations of the same shape cycles if it is preferred for the particular application.

The proposed Lamp allows you to extend the decorative possibilities of lamps of this type due to the implementation of complex dynamic color effects using simple techniques and tools.

The technical result is achieved in that the control device can be made in the form or the control circuit with the controller and/or microprocessor control system.

The technical result is achieved by the fact that the controller can be fitted or inserted microarray, or a microswitch or an optical sensor for quick and easy changing of the timeline.

The technical result is also achieved by the fact that electrical connection can be either the power pins for control devices placed inside the Lamp, or the conclusions of the management device management, hosted outside of the Lamp.

When using the controller forms cyclograms due to limited memory capacity of the controller will be the most simple, does not require significant resources. When using a microprocessor-based device management you can implement much more complex vari the options cyclograms, but they are more expensive Lamp.

Additionally, there may be used various modifications controllers, microprocessor-based systems with different number of software channels for the implementation of our proposed various programs, characterized by durations front rise and fall of each pulse, which range from not less than 1 sec to 300 sec, the durations of the periods in the range from not less than 2 sec to 600 sec, and the fact that LEDs of different colors duration periods are independent of each other, as well as the durations of pauses, which are no more than 2/3 the duration of the relevant period.

The technical result is achieved by the fact that in the proposed Lamp, the program allows the simultaneous emission of LEDs of at least one color.

The technical result is achieved by the fact that in the proposed Lamp program provides simultaneous radiation of the LEDs no more than two colors. In this case, a color change occurs on the periphery of the color chart involving transitions between three pairs of pure colors that are contrasting and eye-catching, including those of color.

The technical result is achieved by the fact that in the proposed Lamp has the same control program various sources what IKI radiation.

There are various modifications of the proposed program, program channels, allowing to improve the aesthetic and emotional perception, to be closer to the optimal psychophysiological effect decorative Lamp due to the soothing flow significantly extended range of color effects, leading to fascinating effect, increase its attractiveness, efficiency.

Further suggested that various modifications of the Lamp, due to the different relative position of its elements.

In one of the modifications Lamp technical result is achieved in that the diffuser is made in the form of a plafond of arbitrary shape, fully closed or partially open.

The clusters are arranged in such a manner that the luminous flux of the LEDs are distributed either over the entire surface of the diffuser-ceiling or in part or parts. Glowing outer surface of the lens-shade in accordance with a given program fluctuates with time varying colors of light.

In another modification of the Lamp technical result is achieved in that the diffuser is made in the form of a reflector, which may be shaped or dome, or bowls, or any other form.

Possible modification of the Lamp, in which the technical result of the temperature is raised to those the diffuser is made in the form of a combination of shade and reflector, and the lens shade is at least partly located inside the diffuser-reflector, groups of LEDs placed inside the lampshade so that at least a part of light beams at least partially distributed over the surface of the lens-shade and diffuser-reflector.

In this modification the color of the reflector and the shade though and change continuously in time, however always coincide with each other, which helps to enhance the aesthetic and emotional perception of the Lamp.

Consider the following modification of the Lamp, in which the technical result is achieved in that the diffuser is made in the form of a combination of shade and reflector, and the radiation source has at least one group of LEDs located inside the lampshade, and at least one other group of LEDs placed between the lens-shade and diffuser-reflector with light flows, mainly distributed on the surface of the diffuser-reflector.

Proposed a modification last modification. The technical result is achieved by the fact that in the proposed Lamp between the diffuser-ceiling and LEDs disposed between the diffuser-platano and diffuser-reflector, there is also a screen of opaque material, and at least one surface of the reflective screen. The screen is designed to prevent at least partially mutual illumination of the diffuser-reflector and diffuser-ceiling. The reflective surface can be performed, for example, from the side of the diffuser-reflector, which helps to enhance the radiant effect generated by the led located between the screen and the diffuser-reflector.

Such modifications seem very attractive because of the contrast of color of the Lamp, which increases its aesthetic and emotional impact.

The technical result is achieved in that the diffuser is made or transmissive, or reflective, or partially transmissive and partially reflective to the radiation of the LEDs and at the same time it is or diffusing or refracting, or both refracting and scattering.

To obtain the above-mentioned combinations of the optical characteristics of the proposed diffusers can be made of different materials, may have different coatings, surfaces, walls can have different intrinsic properties, or they can be made specific in a constructive manner. The result is the optimization of the claimed technical Raza is Tata.

In previous versions, in which there is a diffuser shade, the technical result is achieved in that the material of the lens-shade can be, for example, or milky white glass, or plastic, at least partially transparent, including the color of milk, or any other material, which simultaneously transmitting, refracting and scattering, or cut the vitreous material, for example ogromennoe glass or cut crystal, which is largely refractive. This diffuser shade may be of any shape. It can be made in the form of a sphere, ellipsoid, cylinder, cube, different figurines, candles, toys, dolls, and other arbitrary configurations.

In previous versions, in which there is a diffuser-reflector, the technical result is achieved by the fact that the output cross-section of the diffuser-reflector (output aperture) may be a circle, an ellipse, a letter, number, or have any other arbitrary shape. While the diffuser-reflector and the led radiation source is placed so that the diffuser-reflector surrounded at least partially the incidence of radiation of the LEDs.

To achieve the technical result of the proposed inner surface of the lens, R is flector to do not only reflect, allowing to receive the strong reflection effect along with dispersal of radiation, but also diffuse reflective, including frosted, with a large component of the scattering effect, allowing you to get more soft and smooth radiation.

To achieve a technical result of the proposed diffuser to run from partially transmissive and partially reflective material. The radiation of the LEDs in this Lamp will be partially reflected from the surface of the lens and partly to pass through its walls.

In addition, the technical result is achieved that the output aperture of the lens placed the film, including the polarization interfering. This film can be placed in the output aperture of a partially open diffuser-ceiling and/or diffuser-reflector.

The following modifications Lamp technical result is achieved that the output aperture of the lens is placed a ceiling in the form of a cover of light-diffusing material. It is desirable to have part of the led, the axis of which is mainly perpendicular to the surface of the cover. Diffuser-ceiling - cover may have a different shape: concave, convex, flat, and any other arbitrary shape.

In such modification the technical result is achieved by the fact that the cap is made in the form of lenses made of faceted light-diffusing glass-like material or in the form of a film, in particular, the polarization interfering.

The mixture of radiation of the LEDs of different colors in the offered Lamp is in the internal volume of the lens, on its surface and within its walls.

Such Lamps are very effective, aesthetically.

For any proposed modifications Lamp technical result is achieved in that at least the source of radiation and electrical leads sealed.

Such a Lamp can be used either in terms of potentially high humidity, for example, landscape lighting, or when it is full immersion under water, for example, in various floating or submerged objects, i.e. expanded functionality and added new consumer properties of the Lamp.

For any proposed modifications Lamp technical result is achieved by the fact that he is further provided with ducts for the fluid in the diffuser, a recirculation system with a pump and a reservoir for fluid collection.

This modification has the additional attractive because in addition to using the properties of liquids, including water, in addition to diffuse light from immersed in the liquid radiation source, here significantly increases the effect of the Lamp due to reflecting (diffuse from aawsa) wall (including a partially reflective and partially transmissive) of the diffuser-reflector. It also expanded the functionality and added new consumer properties of the Lamp - it can be used in the form of a fountain, water wall, including those containing elements of advertising media, etc.

The technical result is also achieved by the fact that the form can be different, such as flat, convex, concave, convex-concave, or any other form, including monolithic or composite, required modification of the Lamp, the distribution of LEDs, groups of LEDs on surfaces of a base to obtain the given distribution of the light fluxes on the inner surface of the lens.

The proposed decorative multicolor lamp is new and original set of connection elements, new details of the elements that in combination with the original, non-obvious and a new proposed program control device allows to conclude, that the invention is new and involves an inventive step. We believe it is necessary to emphasize its simplicity and cheapness when applying simple PIC-controllers, which determines its wide applicability in everyday life, in a new small forms.

Implementation of the invention is easy, its elements are easy to manufacture, the technology of their production are known, they are cheap and replaceable. The proposal is the group meets the criterion of "industrial applicability".

The proposed Lamp allows you to get soft smooth ambient (calm) with constantly changing light colors, which creates a sense of calm and has a beneficial effect on the emotional perception. Fascinating, almost unpredictable, relatively slow and almost monotonous change of the color gamut provides a valid and decorative at the same time optimal psycho-physiological effects.

Embodiments of the inventions

The invention is further explained specific variants of its implementation with reference to the accompanying drawings. Examples of the manufacture of the Lamp are not the only, and assume other implementations, the features of which are reflected in the combination of features of the claims.

Consider the first modification. The proposed Lamp (see figure 1, 2) contains a radiation source comprising LEDs 1 and the control device (2) in this case, the control circuit to the controller 2 (hereinafter "control circuit 2"). The LEDs 1 are arranged in three groups of 3, hereinafter referred to as clusters 3, three led 1 different colors (e.g. red, blue, and green) in each cluster 3. Clusters 3 are placed at the corners of a triangle on the Board 4, and in the middle is placed the control circuit 2. Board 4 is placed on the base 5 on the inside of the lens-shade 6 made of glass milky white, globe-shaped, also fixed on the base 5. In this case, the base 5 is a composite: in the first part, placed the card 4, between the first and second parts of the base 5 is fixed diffuser shade 6.

Electrical leads 7, in this case, the power pins 7 through the opening 8, coaxially with the Central axis of the base 5, connected with a source of DC power (figure 3 not shown). The power source may be an AC mains voltage of 220 V DC voltage with a nominal value of, for example, 5 V, 9 V, 12 Century When this diffuser shade 6 will be sufficiently illuminated by mixing radiation of the LEDs 1 of different colors as in the volume of the inside of the lens-shade 6, and on its surfaces is in its walls. LEDs 1 are the desired range of focus of radiation.

Next, consider the different options proposed Lamp.

It is recognized that the source of radiation, which uses LEDs 1 of the three primary colors, namely red, blue and green, you can get the maximum number of colors and shades that are visible to the human eye. So here we are considering this option color set of LEDs 1. Variants of using multiple radiation sources and/or other sets of colors of LEDs 1 are possible and some of them tested, with the resulting effect, as defined earlier. The mixture of radiation of the LEDs 1 a variety of colors occurs in the propagation of radiation in the internal volume of the scatterer, i.e. inside of the lens-shade 6, on its surface and within its walls.

The power management LEDs 1 is carried out in accordance with predetermined programs periodic pulse supply power, the recurrence period of the pulses which are independent of the LEDs 1 a different color. Here the options specified programs are summarized in the Table, but they are not the only, and assume other options specified programs, features which are reflected in the totality of symptoms of the formula invented who I am. Changes in pulse power in time for the LEDs 1 of each color correspond to changes in the intensity of their emissions, which can be illustrated by the sequence diagram of periodic pulses of intensity of radiation of the LEDs 1 of each color (see figure 3 for Option 1, as indicated in columns 1-8 line 1 of the Table).

To achieve a technical result of the offer important as the total duration of each period of the frequency of occurrence of the pulse and the duration of its elements, i.e. the pulse shape and duration of pauses, each of which can be changed independently. In addition, ways to match the durations of periods (with their independence from each other and form of pulses is also considered, since they allow to obtain new interesting color effects.

In columns 2 to 6 of the Table contains the length of periods and elements repeated pulses sequentially for each color: red, blue, green, which corresponds to the cyclograms positions: 9 - circles (radiation intensity red LEDs), 10 - triangles (the radiation intensity blue LEDs), 11 - squares (radiation intensity green LEDs).

Each program includes a sequence of repeated pulses (which correspond to the changes of the pulse power) LEDs 1, consisting of item for your home! the comrade: the rise front of the pulse (corresponds to column 3 of the Table), the peak of the pulse, possibly extended (corresponds to column 5 of the Table), the decline of the pulse (corresponds to column 4 of the Table) and pause (corresponds to column 6 of the Table), during which in our cases, no signal (it can also be very small).

In all variants of the considered programs of length front rise and fall of the pulse considerable - 1 sec or more, so its shape is different from the classic rectangular and may have a trapezoid shape, a pyramid or be similar to a sine wave. The main thing is that the change of the pulse power from minimum to maximum and back was rather monotone, i.e. it is enough smooth, without abrupt jumps (for example, in the known solution-prototype [5] when "instant" on and off duration of the front rise and fall (in the famous case [5] - slice) of the pulse are the magnitude is much less than 1 microsecond, when this is flashing, there is no gradual change of colors). For simplicity, in the examples of the programs reviewed timeline in the form of trapezes or curve similar to a sine wave when the length of the peaks and the duration of the pause can be extremely small. The final result depends on the nature of the curve.

In the first case (line 1 of Table and Figure 3) management is performed by three programme is Mami, for which not only the duration of the recurrence period of the pulses is independent of the LEDs 1 a different color, but are also independent of the duration of all elements of pulses and pauses. The color change will occur in virtually unpredictable trajectory with conditionally "chaotic" for an observer sequence in accordance with all internal chart area color and its boundaries, including pure color. Options 2, 3, 4 differ from option 1, the durations of the various phases (cyclogram on the figures not given).

In variant 2 sequence diagram (figures not shown) provides almost constant simultaneous illumination of the LEDs 1 all (three) colors (with a minimum length of tops and short durations of pauses), then the sequence of color changes will occur in less predictable trajectories mainly inside the chart color conditionally "chaotic" for an observer sequence, and colors will be expanded.

The increase in the duration of the pause leads to a noticeable "gap" in the glow of the corresponding color. If the duration of pauses is high for all colors, the intensity of the Lamp as a whole can be significantly reduced, which is undesirable. Therefore, the duration of pauses is bounded above by a value of 2/3 of the total glutelin the security of the relevant period. For example, see option 3 (figures not shown), where the duration of the pauses have values close to this value (2/3).

In option 4, while the minimum values of the distances of the peaks and durations of the pauses of the received sinusoidal change in the intensity of radiation of the LEDs 1 (figures not shown).

The reduction in the duration of pauses leads to an even more significant shift of the resulting color to the center of the diagram, i.e. in the white area. The emergence of pure colors in this case is quite rare. This option is also of interest, for example, in the case of a decorative Lamp, working in the dark, such as home nightlight or landscape Lamp. Changing shades of white will not be Intrusive on the one hand, and on the other hand, such Lamps will be more attractive than normally used for these purposes.

It is obvious that the proposed approach to programming allows any desired sequence diagram corresponding to a specific application or the request of the consumer.

In the above modification of the Lamp to reach the technical result: improvement of aesthetic and emotional perception, an approximation to the optimality of the psychophysiological effects of a Lamp with a significantly extended range of CEE the new effects, leading to fascinating effect, increase its attractiveness, efficiency, and expanding its functionality and add new properties, reduction and simplification of its operation.

Consider the following modification. Suggested Lamp diffuser shade 6 which is made of frosted glass in the form of an incandescent lamp (see Figure 4 and 5)secured in the housing 12 of the lamp, provided with a cap 13, a typical incandescent lamp. The power pins 7 (figure 4 and 5 not shown) of the control circuit 2 is connected to a source of electrical power (figures not shown) through the base 13. In the case of an AC power source, the control circuit 2 additionally equipped with a built-in miniature transducer (figure 4 and 5 not shown) AC mains voltage to DC voltage to power the actual control circuit 2. The base 5 is installed in the socket 12. On the basis of 5 fixed charge 4, which contains one cluster 3, containing three LEDs 1 three different colors: red, blue, green, and under - 4 set control circuit 2 with a controller with a job program, for example, for option 1. When the Lamp is mixed radiation of the LEDs 1 of different colors as in the volume inside the tube diffuser-ceiling 6, and p is the surfaces and walls. LEDs 1 are the desired range of focus of radiation.

This construction is convenient in use, simple, cheap, can be used as a single, and in various combinations. In this design can be used in standard lamp sockets of various sizes.

Other combinations possible as the number of LEDs 1 in cluster 3, cluster number 3, and their form and their location depending on the problem being solved.

The following modifications (see Fig.6 and 7) diffuser Lamp made in the form of the diffuser-reflector 14 having a shape forming a bowl of earthenware, with an output aperture in the form of a circle, with the inner surface of the reflecting and scattering of radiation of the LEDs. In the area of the proposed vertices forming the bowl of the diffuser-reflector 14 in a centered hole posted one part of the base 5. LEDs 1 in three different colors (red, blue, green) are arranged in six separate lines, mounted on the respective six boards 4, placed on the upper side of the base 5, forming a hexagon.

All the LEDs 1 mounted so that their axis of radiation directed mainly at the inner surface of the diffuser-reflector 14. The control circuit 2 is attached to the upper surface of the base 5. Conclusions Pete the Oia 7 are derived from the base 5 (see the first modification) to the source of DC power (7 not shown). In the upper part of the base 5 is fixed opaque screen 15 not to see unmixed radiation of the LEDs 1. Diffuse reflective screen surface 15 facing the diffuser-reflector 14. When the Lamp on the proposed in the present invention the program is a mixture of radiation of the LEDs 1 of different colors as in the volume limited by the diffuser-reflector 14 and the screen 15, and on their inner surfaces and the depths of their walls. LEDs 1 are the desired range of focus of radiation, and their axes are predominantly aimed at the inner surface of the diffuser-reflector 14.

The following modification of the Lamp (see Fig and 9) differs from the preceding by the fact that the six lines of the LEDs 1 on six boards 4, forming a hexagon, located on the upper surface of the base 5, and the control circuit 2 on the circuit Board 4 is installed in the recess in the middle of the ground between the boards with 4 clusters; there is no opaque screen 15; the output aperture of the Cup-diffuser-reflector 14 is mounted cover 16 (diffuser shade 6) in the form of lenses made of faceted crystal. The LEDs 1 can be mounted in different ways, but the greatest effect is obtained by installing LEDs 1 thus, h is Oba their radiation at the same time and got on the diffuser-reflector 14 and the cover 16. This is achieved, for example, the use of LEDs 1 with a wide radiation angle, for example 90°. Here, when the Lamp according to one proposed in the present invention programs are a mixture of radiation of the LEDs 1 of different colors in the volume bounded by the diffuser-reflector 14 and a lid 16 on the inner surface and the depth of the walls of the diffuser-reflector 14 and the refractive cover 16.

Possible modification of the two preceding modifications of the Fixture so that each circuit Board 4, for each cluster 3 LEDs 1 individual independent control circuits. Colors of these Lamps unpredictable and spectacular.

Another modification of the Lamp, longitudinal and transverse sections of which are depicted schematically in Figure 10 and 11 differs from the first modification (see Fig 1 and 2) those that have been added to the diffuser-reflector 14 of aluminum alloy having an inner frosted microrelief textured surface and surrounding the lower part of the lens-shade 6, made of plastic milk color. The diffuser-reflector 14 is in the form of a bowl with a hole in the middle for fastening the base 5. If this part is not sharp radiation which has passed through the diffuser shade 6, is reflected from a diffuse reflecting surface is rnost diffuser-reflector 14. When the Lamp according to one proposed in the present invention programs the mixing occurs in all the volumes of the parts of the lens, as well as on the surface and part of the wall thickness of the diffuser-reflector 14 and on the surfaces and inside the walls of the diffuser-ceiling 6. Such a Lamp has a soft and unobtrusive radiation while maintaining high efficiency.

The following modifications (see Fig and 13) differs from the preceding by the fact that between the diffuser-ceiling 6 and the diffuser-reflector 14 is additionally on the side surface of the base 5 mounted LEDs 1 in the form of six lines, which are controlled by the second line control circuit 2 (Fig, 17 not shown), i.e. there are two independent radiation source.

During operation at different and variable in time the intensity of illumination of the LEDs 1 of each specific source of radiation in parts of the lens occurs mutually partially mixed continuously variable range of colors. Such mixing occurs in the volumes of the parts of the lens, as well as on the surfaces and side wall thickness of the diffuser-reflector 14 and on the surfaces and inside the walls of the diffuser-ceiling 6. In volume diffuser-ceiling 6 will be more strengthened the influence of the radiation source installed in the diffuser-ceiling 6 and the volume of the diffuser-reflector 14 - a radiation source mounted in the diffuser-reflector 14.

If the radiation sources are installed in different volumes of the lens, are programs that implement various changes color over time, such a Lamp generally has exclusive decorative associated with a dynamic contrast of colors observed in the two volumes of the lens.

If the radiation sources are installed in different volumes of the lens, are programs that implement the matching between a color change in time, such a Lamp has a high efficiency, although less decorative.

The modification shown in Fig differs from the preceding in that it introduced opaque metal screen 15 between the diffuser-ceiling 6 of the glass milky color and LEDs 1 arranged between the diffuser-ceiling 6 and a metal diffuser-reflector 14 with a diffusely reflective inner surface. The lower surface of the screen 15, facing the diffuser-reflector made reflective. By simply working on the proposed program of radiation of the LEDs 1, placed in the side of the base 5, is incident on the surface of the lens-shade 6 and increases, reflected from the mirror surface of the screen 15, and radiation led Halloween gift is s 1, placed inside of the lens-shade 6, is incident on the surface of the diffuser-reflector 14, at least the part that is covered by a screen 15. Otherwise practically prevents the mixing of the radiation of the LEDs 1, installed inside of the lens-shade 6 and between the diffuser-ceiling 6 and the diffuser-reflector 14 with sufficient efficiency of the Lamp.

Possible modification using multiple radiation sources with independent control of different sources and between them have shields, dividing the internal volume of the Lamp in various sectors, which will be covered in different colors. In these cases, management can be performed through separate channels or by using one or more control devices.

Possible modifications with other sets of colors of the LEDs 1 to create different color effects. There are other possible combinations: number of LEDs 1 a different color in the cluster, number of clusters and their shape, their location depending on the problem being solved.

Other various modifications suggested Lamp, such as various forms of scatterers, the location of the LEDs, etc.

For example, the ceiling 6 may be made in the form of toys, such as action figures dolls-dolls, the Tacana or cylinder, made of partially transmissive light-diffusing material (figures not shown).

Possible modifications of the proposed Lamp in the form of any letters, numbers. Figure 15 shows a longitudinal section of the letter "O". The output aperture of the metal housing of the diffuser-reflector 14 has a diffuser shade 6 in the form of a cover 16 made of opaque plastic. On the basis of the diffuser-reflector 14 over the entire length of the body evenly placed Board 4 clusters of 3 LEDs 1 - three LEDs of different colors in each line. Labels and signage of these letters will be much more attractive, because the color of these letters will be continuous and unpredictable change, and at the request of the consumer this can be either synchronous color changing for all of the letters or characters of the inscription, or each of them is controlled by an independent program.

Almost all of the proposed modifications with proper sealing at least the radiation source and the electrical outlets can be operated in a wet environment.

Interesting different floating or vodopogruzhaemy toys with highlighted parts, colours which change according to independent programs. Examples of such toys can be balls, boats, flowers and many other items.

All mo what changes are possible using the proposed variants of the control device 2 as a stand-alone (control circuit with the controller 2 or miniature microprocessor control system 2), and external (mainly microprocessor control system 2) using appropriate electrical terminals 7 (power pins 7 for Autonomous control devices 2 and conclusions management 7 for external control devices 7).

The proposed modification of the Lamp can vary the implementation of the controller control circuit 2. In one of them the controller is equipped with plug-in microarray, another micro switch, the third optical sensor. Stated conditions control can be implemented in all versions of the controller.

In the above modifications of the Lamp to reach the technical result: improvement of aesthetic and emotional perception, an approximation to the optimality of the psychophysiological effects of a Lamp with a significantly extended range of color effects, leading to fascinating effect, increase its attractiveness, efficiency, and expanding its functionality and add new properties, reduction and simplification of its operation.

The proposed Lamp allows you to extend the decorative possibilities of lamps of this type due to the implementation of complex dynamic color effects using simple techniques and means what. In addition, it looks like a really decorative, its glow aesthetically and he has a strong emotional impact, improving physiological (psycho-physical) condition of the individual.
