The invention relates to the control of electric light sources, and more specifically to systems lighting or illumination using LEDs, and can be used for decorative and basic lighting of any objects, especially objects of small architectural forms, for color ads and the like.

Currently increasingly used for illumination or backlight LEDs.

Known methods of illumination [US 5934798, 1999; EN 2207635, 2003], in which are located on the surface of the labels, symbols, or images are covered on the outside with the help of LEDs with red, green and blue radiation spectra and brightness of each led group one of the emission spectrum changes with corresponding current regulator.

The main disadvantage of these methods is the fact that the highlighted information is not discernible, especially in the conditions of changing ambient light, with this technology it is impossible to create illumination in the form of a rapidly changing colour dynamic scenes.

Known methods and led systems designed for decorative illumination or light objects, such as theatrical scenes that use controllers with analog control [US 6016038, 2000; US 6150774, 2000].

In such systems, the controller has multiple outputs to the channels, designed for a specific load. Management is to create a certain voltage at a certain channel. This scheme has all the disadvantages of analog control and as a consequence there are few forms of output voltage, implemented by a hardware way. In addition, the number of controller channels specifies the number of managed elements in an led system that limits the application and reduces the functionality of this scheme.

The known control system illumination using controllers with digital control of led lighting [US 6166496, 2000; US 6211626, 2001]. In such systems, the controller has multiple output channels designed for a specific load. Management is to change the frequency or duty cycle of voltage pulses on a particular channel. These controllers there is no communication interface and the ability to change the order and form of the generated pulses. In addition, the number of controller channels specifies the number of managed elements in an led light, which limits the application and reduces the functionality of this scheme.

There is a method of lighting and illumination, in which use controllers that support the standard Protocol US1TT DMX512 [US 6292901, 2001]. This proto is ol was created for the exchange of digital data between controllers and power regulators stage light sources. The physical layer of this standard is implemented on the basis of the standard industrial interface, known as RS-485. Standard USITT DMX512 (1990) suggests that the subscribers are spaced at a sufficient distance (the maximum distance of 1000 meters) and each subscriber has an RS-485 interface. Thus, with respect to the led illumination each managed element must have RS-485. In systems led illumination controlled element is an led module. The distance between the led modules ranges from a few centimeters to several tens of centimeters.

The availability of each managed element led illumination RS-485 significantly complicates the scheme leads to an increase in the overall dimensions of the led modules, and limit functional use and applications. The disadvantage of this scheme is that the number of channels determines the number of control elements led backlight. From this position out, combining the led modules in the matrix system [US 6611244, 2003; US 6661521, 2003; US 6680834, 2004], which leads to further complication of the device and the technology of led illumination.

All known systems and methods do not allow for quick and cheap enough to create complex lighting systems on the basis of when modiodal and simultaneously rapidly change colour dynamic scenes to control the color and dynamics of each of the led module when the dimensions of the led module is close to the geometric dimensions of the led.

The present invention is to accelerate and simplify the process of creating and changing colour dynamic scenes for complex models led illumination.

The problem is solved in that they create in the computer using the user interface, the frame model illuminations, which have elements that mimic led modules, as they should be located on the object of illumination, then convert the created frame in an animated film in the form of colour-dynamic scenes, in which change color and brightness, and then set on illuminarium the object in accordance with a given model of led modules connected in series information cable, which is connected to the controller, which in turn is connected to the computer, transfer the animated movie from the PC to the controller, turn off the computer by changing the frequency and duty cycle enable LEDs, reproduce colour dynamic scenes created in the computer.

The task can be solved, if there is used a complex system of illumination that contains the computer connected to it via the interface port control is EP, connected with one end of the information loop, consisting of one color channel for monochrome models, the three color channels (red, green, and blue) for color models, gate, marker and supply voltage, led module, placed sequentially on the information loop and containing on input triggers for each color channel, connected to information inputs: one for monochrome patterns and triggers for each color channel (red, green, and blue) for color schemes, and the trigger for the marker, which input is connected to the end of the information loop feed gate, D-input for signal token, and the output connected to the inputs of flip color channels, the output of which is set transistor switches connected to the LEDs, while the outputs of the previous triggers the led module are inputs of the triggers of the next led module.

To expedite the process of creating an animated film serves to change the color and brightness of the colour dynamic scenes to use the graphical dependence, in which in the upper part of the y-axis of post scale of brightness from zero to one hundred, and in the bottom - color palette, and on the x-axis - selected group of frames with color equal to the sum of the values of brightness and color of the axis.

In the depending on whether what are models of illumination, colour dynamic scenes give a certain color and brightness or each frame, or each element of the framework for the model of illumination in each frame, or group of elements of a skeleton model of illumination in each frame, or some frames, or/and each element and/or group elements of a skeleton model of illumination, or each frame and/or some of the frames or all options together.

Comparative analysis showed that the claimed method differs from the known fact that, using the user interface, create a framework model illuminations, which have elements that mimic led modules, as they should be located on the object of illumination, then convert the created frame in an animated film in the form of colour-dynamic scenes, in which change color and brightness of each element simulating an led module mounted on illuminarium the object in accordance with a given model of led modules, transmit animated film in the controller by changing the frequency and duty cycle enable LEDs to reproduce a given model of illumination, that allows to judge about the criterion of "novelty."

Announced a comprehensive system to control the illumination differs from the known solutions is the fact that the led modules sequence is correctly connected information train and contain LEDs, United through transistor switches to the outputs of triggers, each of which is connected with its color channel and one with the marker information of the train, which also allows you to judge the compliance of the integrated illumination the criterion of "novelty".

Comparative analysis with other decisions in this area did not reveal technical solutions containing characteristics that match with the distinctive features of the claimed invention that allows you to judge the criterion of "inventive step".

The invention is illustrated by drawings, where figure 1 shows a structural block diagram of a system for illumination, figure 2 - wiring diagram installation of led modules in the information loop, where (a) - for color channel (red, green, blue) and (b) for monochrome (one color) channel information to train, figure 3 - block diagram (a) - full color (three color channels - red, green, blue) led modules, and (b) monochrome (one color channel), 4 - the block diagram of the controller figure 5 - wiring diagram of the controller 6 is an example of the construction of the frame model illumination and convert it into a color dynamic scenes, Fig.7. an example of a graphic based interface software control, Fig is an example implementation of the method illum the nation for a specific object.

A complex system of illumination (figure 1) contains the personal computer 1 connected to it through a Converter USB-RS 4852, twisted pair cable 3, a controller 4 that is connected to an information train 5, with consistently placed it led modules 6.

Led module 6 contains or multiple monochrome 7, or a full-color 8 led (figure 2 and 3), the transistor 9 keys, triggers the color channels 10 and the trigger of the marker 11. Led elements 6 interconnected information train 5, through which data are transmitted: color channel (one channel - for example, red - 12) for monochrome schemes (b) and three channels - red 12, green 13 blue 14) for color schemes (a), the marker 15, the gate 16, the supply voltage 17(+5V) and zero voltage 18. The controller 4 to control the led module 6 consists of a microcontroller 19, the flash memory 20 and port 21 of the RS-485 interface.

The method consists in the following.

In the program window using its GUI tools to create a framework of a given led illumination (6), i.e. simulators led module 6 is positioned so as they will be located on the object of illumination. Next, using the color palette painted each simulator led module (6). Thus, it appears one frame. After you create one to the DRA creates the following frames, want to paint the same way. The number of frames is determined by a given model of illumination.

The result is an animated film which transmits it will look like the model of illumination.

To expedite the process of creating an animated film technology to create colour dynamic scenes can be performed as follows.

After creating a skeleton for a given model illumination activate the frame in the window where you can select one or more simulators led modules 6. Determine the number of frames that will be subject to changes, and build the graphical dependence using a user interface (Fig.7). On the graphics based on the ordinate axis (Y) at the bottom, have a color palette in the upper part of the brightness scale, and the abscissa axis (X) have selected frames, the color of which is determined from the sum of the values of brightness and color of the axis of ordinates. Thus painted all groups of led modules, a common colour dynamic property. For monochrome scheme is up to 256 gradations of brightness. For color schemes up to 256 gradations of brightness for each color channel, or up to 256×256×256=16,777,216 colors gradations. The number of gradation of brightness of the channels is set programmatically.

After that programmed the model p is redesa in the flash memory 20 of the controller 4 through the port 21 of the RS-485 interface. Next, the controller displays the data in the loop 5 led modules 6. The controller must be in the immediate vicinity of the plume with led elements, and so located on its base RS-485 interface allows access to the controller from a distance of up to 1000 m, which is very important because of the illumination system and illumination are usually in hard to reach places. The presence of addressing controller allows you to connect multiple controllers, each with its own bus led modules.

Data from loop 5 arrive at the D-inputs of flip color channels 10 of the led module 6. The gate 16, in the form of logical units, "1", arrives at the s-input of the trigger marker 11. At the same time the marker, in the form of logical units, "1", is supplied to the D-input of the trigger marker 11. On the Q-output of the trigger marker 11 and respectively To the inputs of flip color channel 10 is formed by a logical "1", Yves accordance with the data on the D-inputs of flip color channels (10), their Q-outputs are generated logical "0" or "1". Logical unit "1" opens the corresponding transistor switch 9, and the corresponding group of LEDs 7, 8 lights up. The Q-output of the trigger marker 11 is at the same time D-input of the trigger marker 11 of the next led module 6. Thus, the token moves from one trigger token is different for all led modules writing in the trigger channel color data and turning on or turning off the corresponding LEDs.

After creating a skeleton for a given model illumination activate the frame in the window where you can select one or more simulators led modules 6. Determine the number of frames that will apply the changes and build the graphical dependence using a user interface (Fig.7). On the graphics based on the ordinate axis (Y), at the bottom, have a color palette in the upper part of the brightness scale, and the abscissa axis (X) have selected frames, the color of which is determined from the sum of the values of brightness and color of the axis of ordinates. Thus, painted all groups of led modules, a common colour dynamic property. For monochrome scheme is up to 256 gradations of brightness. For color schemes up to 256 gradations of brightness for each color channel, or up to 256×256×256=16,777,216 colors gradations. The number of gradation of brightness of the channels is set programmatically.

After that, the programmed model is passed into the flash memory 20 of the controller 4 through the port 21 of the RS-485 interface. Next, the controller displays the data in the loop 5 led modules 6. The controller must be in the immediate vicinity of the plume with led elements, and so is the output at its base RS-485 interface allows access to the controller from a distance of up to 1000 m, what is very important, since the illumination system and illumination are usually in hard to reach places. The presence of addressing controller allows you to connect multiple controllers, each with its own bus led modules.

Data from loop 5 arrive at the D-inputs of flip color channels 10 of the led module 6. The gate 16, in the form of logical units, "1", arrives at the s-input of the trigger marker 11. At the same time the marker, in the form of logical units, "1", is supplied to the D-input of the trigger marker 11. On the Q-output of the trigger marker 11 and respectively To the inputs of flip color channel 10 is formed by a logical "1", and in accordance with the data on the D-inputs of flip color channels (10), their Q-outputs are generated logical "0" or "1". Logical unit "1" opens the corresponding transistor switch 9 and the corresponding group of LEDs 7, 8 lights up. The Q-output of the trigger marker 11 is at the same time D-input of the trigger marker 11 of the next led module 6. Thus, the token moves from one trigger token to another for all led modules, registering in the trigger channel color data and turning on or turning off the corresponding LEDs.

The color palette is realized by changing the brightness of each color, the method of changing the frequency and duty cycle of the led light.

Software both the biscuits embodies the technology of the organization led illumination or backlight, and methods for creating and managing color dynamic scenes on the basis of the patent system.

An example of the method of illumination.

For the Shoe store was established advertising sign (Fig).

First, have developed a General scheme and overall appearance of this advertising signs in the form of two rings of different diameter and the circle with the words "Your shoes", on the ground after a round ring depicts different kinds of shoes. This picture advertising signs was entered into the computer, where, using the user interface was developed framework for the model of illumination, in which the imitators of led modules were placed on the sign for 4 rings, the first of which is placed on the circumference of the circle with the words "Your shoes", the second ring of LEDs placed at some distance and made of grouped two of the led module on each image of the shoes, on the third ring also led modules were placed in the center of images of shoes, and on the fourth ring - led modules were placed on the toes in the Shoe drawings. When creating this advertising signs used full-color led modules, i.e. each module can transmit any of 16 million colors.

Next were developed colour dynamic scenes, change the color and brightness in accordance with the constructed graphical depending what Yu (Fig.7), then the skeleton model was transformed into an animated film, a preview of which showed the possible negative effects of visual perception, then animated film several times rebuilt, yet did not meet the necessary requirements of the customer.

In accordance with the designed software complex frame designs signs were installed led modules, integrated information train, to the connector which is connected to the controller. Next were connected power supplies and closed the case signs. Then using twisted pair cable, through Converter USB - RS 485 controller connected to the computer. Animated film created in the software of the complex was recorded in the controller memory. After recording, and disconnection of the computer led backlight started to play animated film, recorded in the memory. After testing is complete, an advertising sign posted on the wall of the building.

In the practical use of advertising signs at the customer changed several times colour dynamic scenes, for which the new animated film was recorded in the controller memory, which was connected to the computer.

Thus, when using the inventive method and integrated system, you can quickly create is to complex and diverse models and types of illumination and illumination with the ability to control each led module when the geometric dimensions of the led module commensurate with the size of the light-emitting diodes, with the ability to quickly and visually create models of illumination and colour dynamic scenes and then write them to the controller from a distance of up to 1000 meters.
