The technical field to which the invention relates.

The present invention relates to the spotlight with Fresnel lens, with adjustable angle of aperture opening of the light beam, which contains the reflector, the lamp and at least one Fresnel lens.

The level of technology

In the case of conventional lights with Fresnel lens part, appropriate lighting equipment, in General, includes lamp, Fresnel lens and a spherical auxiliary reflector. The filament of the lamp is usually essentially motionless in the center of the spherical reflector. Therefore, part of light emitted by a lamp, is reflected in the opposite direction to the latter, and supports the light emitted in the forward hemisphere. This forward looking light focused by the Fresnel lens. The degree of optical focus, however, is a function of the distance between the Fresnel lens and the lamp. The narrow optical focusing occurs when the filament lamp is placed in the point focus Fresnel lens. The result is a quasiparallel beam path, also called a light spot. When reducing the distance between the Fresnel lens and lamp aperture angle of the output beam of light is gradually increased. This results in the path of the divergent light beam, which is also called salivas the m light. However, the drawback of such projectors is in a bad light, in particular, during operation of the light spot, as in this case, the Fresnel lens covers only a relatively small range of spatial angle of the lamp. In addition, the disadvantage is that a large proportion of light that is reflected by the spherical reflector, again falls on the filament of the lamp is absorbed and additionally heats the filament of the lamp.

In DE 3919643 A1 describes floodlight with reflector, aperture and Fresnel lens. The light generated by the light change through the regulation of the light source. Thus ensure to change the brightness of the light. The brightness control provide by changing the distance between the vertex point and the reflector and between the aperture and the reflector.

In DE 3413310 A1 describes floodlight with lamp and reflector or lamp and a composite lens. Spot additionally has a diffusion screen or mirror, both these elements are arranged at an angle of 45°. The mirror deflects the light, and a diffusion screen diffuses the light. Different angles of radiation of the light beam produced by the movement of the diffusion screen.

In DE 10113385 C1 described spotlight with Fresnel lens, in which the Fresnel lens is a composite lens, the focus point which is on the side of the light source is located in the ulozhenie, it provides a mode of a light spot, approximately at the point of focus of the elliptical reflector that is located farther from the reflector. This prevents excessive heating of the lamp due to the reflected backward light. However, with increasing degree of miniaturization of the light source, for example, in the case of a powerful discharge lamps high pressure, in the middle of the field illuminated by the light, you may receive a strong shaded area, which cannot be compensated or which can be compensated only by using diffusion devices with large loss of light. Even when conventional diffusion device used to prevent the formation of the image of the center of radiation of the light source, they only partially allow to solve the problem if you can solve it at all, as in this case, at least, shaded average input angular aperture must also be evenly lit in each position of the spotlight with Fresnel lens. However, definitely there is a considerable loss of light in the position of the light spot, in particular, since in this case there is only a very small angle of aperture of the shaded area, whereas in the case of conventional Fresnel lenses with diffusion devices always use the entire area of the d ' Fresnel lens for scattering light field.

Disclosure of inventions

The present invention is directed to the spotlight with Fresnel lens, which provides the formation of an evenly illuminated light field while obtaining a high efficiency.

This goal is achieved in a surprisingly simple way by using the spotlight with Fresnel lens according to claim 1 of the claims and the lighting device according to claim 19 claims.

The authors of this application have determined that high light loss can be prevented in a surprisingly simple way using a diffusion screen. Particularly preferred in this case to establish a diffusion screen on the Fresnel lens so that in a particularly preferred way he has a round shape and is installed in the center of the Fresnel lens.

In this embodiment, it is possible to effectively eliminate dark areas in the middle of the field light in any position of the spotlight with Fresnel lens, and thus no longer be a considerable loss of light in the position of the light spot of the reflector.

It was unexpectedly found that from the point of view of geometrical optics, the beam of light passing from the reflector to illuminate a smaller area at the location of the Fresnel lens, exactly in inverse proportion to the fraction of scattered light.

The authors of this application used this effect in accordance with the present which m invention, to obtain the automatic or adaptive system for mixing light, which, in addition to the formation of light using geometrical optics, provides simultaneous mixing and adjustable spotlight with Fresnel lens using only the fraction of scattered light that is required for this position.

This is almost optimal mixing of light to provide the corresponding desired light distribution below for brevity denoted only as the ratio of the mixture.

Essentially, for each position of the reflector such automatic light mixing system provides the correct mixing ratio and, thus, always allows you to create very evenly lit light box, without excessive loss scattering.

The choice of diameter of the diffusion screen in relation to the remaining surface of the Fresnel lens in this case can be used to determine the mixing ratio of the Fresnel lens, illuminated the entire area, and the angle of aperture of the scattered light can be determined by the scattering properties of a Fresnel lens.

In addition, the scattering effect of the embedded diffusion screen can be changed so that, for example, areas with high dispersion will be located in the middle of the diffusion screen, and the area with lower races is jeevanam will be located on its edge. As a result of this highly focused beam of light is additionally expanding, and thus it is possible to use a very wide angles of illumination.

Alternatively, it may be not only formed abruptly ending edge of the diffusion screen, but it can be attached to this form, which provides the effect of continuous reduction of the degree of scattering, and also it can be carried out both under and above the Fresnel lens. Thus, it can be obtained from other adaptation of mixing depending on the situation.

In the case of the preferred embodiment of the diffusion screen can be installed on the entrance side of light, and on the output side of the world. In addition, preferably, there is a possibility of installation of diffusion screens on the entrance side of light and side light output. In the case of the latter option, the execution is also possible to use diffusion screens, which have, for example, different spatial degree of scattering.

We will refer to the application filed on the same day, on behalf of this author called "Optische Anordnung mit Stufenlinse" ["Optical device with a Fresnel lens"], disclosure of which is fully described in the disclosure content of the present application by reference.

At the same time is supported by the uniformity of the illumination level of the whole Olya light, as shown, for example, in figure 6, as for the position in the light spot, and the provisions of the flood light.

In accordance with the present invention proposed an elliptical reflector with a large aperture. The position of the light spot regulate due to the fact that the filament lamp emitter type black body, in particular a halogen lamp, or a bit of the arc is placed in the focus point of the ellipsoid on the side of the reflector, and the second focus point of the ellipsoid, which is located farther from the reflector, is set to approximately the actual point of focus from the reflector Fresnel lens.

The light reflected by the reflector focuses almost entirely at the point of focus of the ellipsoid, which is located farther from the reflector, before entering the Fresnel lens. The filament of the lamp or discharge arc, which is located at the point focus Fresnel lens on the side of the reflector, is projected to infinity after passing through the Fresnel lens, and the light thus converted into an almost parallel beam.

When the correct choice fragile aperture of the reflector and Fresnel lens light reflected by the reflector, is almost completely captured by the Fresnel lens and is emitted forward in the form of a narrow beam spotlight.

The angle of aperture of the beam of light, you who tamago of the Fresnel lens, you can almost arbitrarily increase in the case of the first variant execution by a corresponding change in position of the lamp relative to the reflector, on the one hand, and by the location of the Fresnel lens at a certain distance from the reflector, on the other hand.

Thus, it becomes possible to maintain the good properties of the normal lights with Fresnel lens with respect to the uniformity of illumination level when these changes in length are produced on the basis of a properly chosen positive connection.

One of the embodiments of the present invention is that the elliptical reflector contains a metal or a transparent dielectric material. It is preferable to use as dielectric materials, glass and polymeric materials or plastics, which may be coated with metal, for example aluminum.

Alternatively, or in addition, in one embodiment, the transparent dielectric material, one of the two or both surfaces of the reflector contain a system of optically thin layers to obtain a reflective surface. Floor Fresnel lens, preferably, contains a system of dielectric interference layers, which modifies the spectrum of light passing through it. Thus, predpochtitel is about, there is the possibility of reflection components of visible light and invisible components, in particular components of thermal radiation are ignored.

In General, both the reflector and Fresnel lens and/or diffusion screen may be coated at least on one side, for example in the case of plastics can be coated as a layer that protects from scratches, and/or non-reflecting layer.

In another preferred embodiment of the invention contains a metal coating on one or both major surfaces of the reflector.

In another alternative embodiment, the reflector may also be a metal reflector, which can be used as uncoated and coated with dielectric or metal, to provide the required spectral properties and corrosion resistance.

The preferred embodiment of the present invention contains the spotlight with Fresnel lens, in which the light-reflecting surface of the reflector, part of the area which, preferably, contains faces formed so that it scatters light, and none of the surfaces, one or two surfaces of the Fresnel lens made in the form of patterns, scattering the light. This provides a fixed proportion of the superposition of the races is eannaso light relative to light, the projected geometrical optics, which can reduce the dark rings in the light field.

Fresnel lens, preferably, made from tempered glass, preferably processed by the method of thermal quenching to ensure, in this way, higher strength and resistance to thermal loads.

The present invention is directed to the use of spotlight for architecture, medicine, cinema, theater stages, studios and pictures, as well as for use as a pocket flashlight.

In preferred versions of the diffusion screen can be installed on the entrance side of light, and on the output side of the world. In addition, preferably, there is a possibility of the diffusion screen on the entrance side of light and side light output. It is also possible, in the case of the latter option, perform, use, diffusion screens, providing a variety of scattering, such as screens, which provide different spatial scattering.

The implementation of the invention

In the following detailed description assumes that identical numbers of links denoted by identical or similarly acting elements in various respective embodiments of execution.

Consider figure 1, which shows an embodiment spotlight with Fresnel lens position of a light spot. Spotlight with Fresnel lens, essentially includes an elliptical reflector 1, lamp 2, which you can use an incandescent lamp, in particular a halogen lamp, light emitting diode, a set of light-emitting diodes or gas discharge lamp, and the Fresnel lens 3, which is a collecting lens, preferably a PLANO-convex Fresnel lens.

In the figure 1 at the point F2 focus of elliptical reflector 1 that is located farther from the reflector, to some extent imposed on the left side of a real or positive point F3 of the focusing lens 3 Fresnel.

The beam 4 light emitted from the spotlight, as indicated on the drawings only schematically rays passing through the outer edge.

The figure 1 also shows the distance between the Fresnel lens 3 and the front edge of the reflector 1 and the distance b between the lamp 2 and the vertex point of the reflector 1.

the position of the light spot set thanks the filament of the lamp or discharge arc lamp 2, essentially installed at the point F1 focus of the ellipsoid 1 reflector located on the side of the reflector.

The light reflected by the reflector 1 is sent in this position almost completely to the point F2 focus of the ellipsoid 1 located further away from the reflector. Located on the left side of a positive or a real point F3 of the focusing lens 3 Fresnel with approximately coincides with a point F2 focus of the ellipsoid reflector.

In the near zone of the figure 1 you can also see how the aperture 5 within the reflector 2 acts as the shaded area 6 for the path of the parallel beam of field 4 of the light.

Within the lens 3 Fresnel is a round, located in the center of the diffusion screen 7, which provides a certain ratio of scattered light and a certain angle of aperture of the scattered light. As a result of this get a certain mixing ratio of scattered light with respect to the light projected geometrical optics by means of a lens 3 Fresnel.

Alternatively, this option perform the diffusion screen 7, in another embodiment, the degree of scattering gradually changes along the radius of the diffusion screen 7 so that more strongly scattering region are located in the middle of diffuzionnogo screen 7, and less strongly scattering region are located on its abruptly ending edge.

In yet another alternative embodiment, the edge of the diffusion screen 7 not only abruptly ends, but it is also designed in such a way that the scattering is steadily decreasing, and it can also be located under or above the Fresnel lens.

In other embodiments, the mixing ratio depending on the situation, thus, is used as the function of the system so that the specialist in the art can always obtain the optimum mixing ratio for the formation of a uniformly illuminated field of light, and also light fields that are supporting some local increase in the intensity of illumination.

On figure 1 you can also see that the position of the light spot only a small part of the total light passes through the diffusion screen 7.

Thanks diffusion screen 7, provides a very uniform illumination, as shown for the position of the light spot by the line 8 in figure 6, which shows a logarithmic representation according to the angle of aperture of the light intensity spotlight with Fresnel lens.

The figure 2 shows an embodiment spotlight with Fresnel lens, presented in figure 1, in the first position of the flood of light, in which the focus point F of the reflector 1, farther away from the reflector, mounted approximately on the surface of the lens 3 Fresnel located closer to the reflector.

The offset value and related to the position of forming the light spot, in this case a certain way is changed by a mechanical guide.

This design is, in principle, corresponds to the design spotlight with Fresnel lens, depicted in figure 1. However, in figure 2 it can clearly be seen that as the angle of aperture of the beam 4 light also increases the shaded area 6.

However, since in this position a very large portion of the light falls only on a small area in the middle of the diffusion screen 7, this area in particular can be configured so that the front lobe of its scattering is approximately compensated appropriately shaded area 6 in the far zone or in the far field. You can also make reference to figure 6, in which the line 9 presents the lighting conditions, for example, provisions for flood light.

Consider the below figure 3, which presents an embodiment spotlight with Fresnel lens shown in figure 1, in the second position flood light with even greater aperture angle than in the figure 2, at this point F2 of the focusing reflector 1, which is located farther from the reflector, PR is Ezerets lens 7 Fresnel forward from the surface of the Fresnel lens 7, located further away from the reflector.

In this case, illuminated a large area of the diffusion screen 7 than in figure 2, and its full behavior of the scattering can be adapted to the conditions of this provision, flood light.

As shown in figure 3, an additional extension beam 4 are given as an alternative or in addition to providing flood light presented on figure 2, by changing the distance b of the lamp 2 from the reflector 1. When moving the lamp 2 in the direction of the reflector 1 are even less focused beam of light emerging from the reflector, resulting in increased output angles at the exit of the lens 3 Fresnel.

To maintain a uniform level of lighting, especially in the preferred embodiment, the change of the location of the elements by an appropriate selection of forced relationships, which establish a certain ratio of the change in a and b, which, however, are not represented in the drawings.

Distances a and b can in one embodiment be changed manually, for this purpose you can use the axial guiding of optical components.

Another preferred embodiment of shown in figure 4. In this embodiment, which essentially corresponds, except for ancillary the aqueous reflector 18, variants of execution described above, the light from the lamp 2, which extends to the right side in the figure 4 and is incident on the reflector 1, is directed to the reflector 1 through the auxiliary reflector 18. Therefore, it is possible not only to use the light, which is only represented for example by the light beam 19 and which would not be used for lighting without auxiliary reflector, but also probably be used to provide the desired light distribution portion of the light which otherwise directly fell on the Fresnel lens 3.

The shape of the auxiliary reflector 18 is preferably chosen such that the light reflected from it, misses again by means of radiation of the lamp 2, such as filament or discharge zone, and does not create additional unwanted heat.

Alternatively, the auxiliary reflector 18 can be installed inside and/or outside glass of the lamp housing 2. To this end, the glass of the lamp housing may have an appropriate shape to provide the desired directional reflected light. Figure 5 shows as an example used in the present invention, the Fresnel lens 3 with diffusion screen 7. The Fresnel lens 3 contains the main transparent body 10 and system 11 rings lens f is anela 11 with the ring sections 11, 12, lens 13, within which there is a round of the diffusion screen 7.

Diffusion screen 7 has a corresponding structure or contains faces 15, 16, 17, providing a dispersion, which can be accurately determined over a large area, as described in the publication entitled "diffusing screen in the application for a German patent of the present applicant's DE 10343630.8, which was filed on September 19, the Office of patents and trademarks in Germany. The disclosure content of this application is also described in detail by reference in the disclosure content of this application.

The present invention, however, is not limited to these previously described variants perform diffusion screens.

The above-described spotlight with Fresnel lens is particularly preferable to use in lighting kit with power pack, which has a much smaller size as compared with the prior art. When the power light is equal to the power devices of the prior art, this power supply can be made smaller in terms of electrical and mechanical parameters, because the spotlight with Fresnel lens in accordance with the present invention has a significantly higher luminous efficiency. This provides less weight and requires less space to store and transport.

In particular, when using a cold light reflectors, it leads to the decrease of the total heat load on the illuminated people and objects.

In addition, the spotlight with Fresnel lens in accordance with this invention also, preferably, can be used to increase the luminous efficiency of the pocket flashlight.
