Description

The invention relates to the field of lighting, and more specifically to methods and devices for the formation of various lighting modes, and can find application in medicine (endoscopes), floodlights, transport equipment and other household appliances.

Known light-optical scheme of the light device used in endoscopic devices (see SU 1529005 A1, CL F 21 V 8/00, 1987).

This system consists of a single light source (incandescent lamp) installed in the focus of a paraboloidal mirror, at the output of which there is a fiber-optic focon that passes into the fiber. This design determines the consistency of the beam path and the size of the light spot and the aperture of the part of the system located in front of the fiber with the dimensions of the fiber end.

The most significant drawback is the relatively low efficiency of using the light flux of the light source.

A known method of forming a light beam for various purposes for vehicles and implementing their designs, built on the projection principle of forming a light beam (see Germany patent No. DE 3406876 C1, CL F 21 M 3/08, 1984, as well as French patents No. 2558236, class F 21 M 3/14, 1985, Germany No. 3523029 A1, class F 21 M 3/14, 1985).

This method consists in the concentration of radiation from a single light source (incandescent lamp) with a polyellipsoid reflector while simultaneously transforming the configuration of the light beam formed by the reflector in the region of its second foci with the formation of a zone of maximum illumination in this plane and then projecting this image into a specific place. In the case of the formation of low beam and fog lighting modes, the process of shielding the light beam is also added.

The designs of such light devices contain a polyellipsoid reflector, a light source with a filament placed in one of the focuses of the reflector, a screen with a configuration that mirrors in shape with the boundaries of the light distribution created by the light device, and a diffuser made in the form of a condenser lens, the focal plane of which also coincides with the second focal plane of the reflector.

The design of lighting devices with a similar principle of forming a light beam has a number of significant drawbacks that reduce the efficiency of their use.

The most significant drawback is the relatively low efficiency of using the light flux of the light source, due mainly to two reasons:

firstly, due to the fact that for the formation of light beams of certain lighting modes, such as "dipped beam" and "fog light", the position of the cut-off line of the screen is higher than the optical axis of the reflector, but it is this part of the light flux concentrated by the latter in the region of the second focus, shielded, due to which the lighting characteristics of the light device are reduced;

secondly, such a light-optical scheme does not allow the use of a reflector with large viewing angles, since the radiation from the zones of the reflector lying on its periphery, i.e. close to the light hole, they won’t get on the lens of the diffuser when it is made in the required dimensions (40 ... 60) mm, and therefore such a light-optic design either excludes the use of reflectors with a large viewing angle or requires a significant increase in the diameter of the lens of the diffuser, which in turn "nullifies" the advantage of the projector-type light distribution distribution of the light device. For this reason, this method of forming a light beam is not used in the implementation of the high beam mode.

In addition, one of the important drawbacks of the indicated design variants of the lighting device (especially in low-beam headlamps) is the very high gradient of illumination of points lying on both sides of the cut-off line (in the dark and bright light distribution zones), i.e. the presence of a very clear cut-off border, which significantly degrades its performance, since in this case it requires very precise adjustment on the vehicle and its effective use is possible only if there is an automatic corrector of the position of the light beam relative to the roadway and the vehicle is very accurate adjustment on the vehicle means and its effective use is possible only if there is an automatic corrector of the position of the light beam relative to zhnogo fabric and the vehicle.

No less important is another significant drawback of these designs - the presence of colored stripes in the light distribution of the light device, the appearance of which is due to chromatic aberration on the lens. Moreover, since eliminating the effects of chromatic aberration is impossible with a single lens, and it is only possible to slightly reduce their effect due to the complexity of the lens design and very precise adjustment of its position relative to the screen, despite the complexity of the design, and therefore its cost, the use of these light devices will certainly create discomfort for drivers of oncoming vehicles and thereby contribute to an increase in the number of road accidents.

A very important drawback also inherent in these technical solutions is the departure from the principle of unification as a general approach to production efficiency, which is also characteristic to a large extent for traditional lighting fixtures. Since in these technical solutions the formation of light distribution boundaries is carried out by projecting the screen onto the plane of the roadway, it is obvious that when implementing designs of lighting devices for various purposes (high beams, low beams, fog lights), the requirements for light distribution of which differ significantly from each other as in terms of the illumination at the control points, and in the magnitude of the scattering angles of the light beam in the horizontal and vertical planes, it will be necessary to use the design of various reflectors, i.e. reflectors with different focal lengths, screens with different configurations of the trim line and lenses with different focal lengths. Thus, it turns out to be impossible to construct a structure capable of satisfying the requirements of various lighting modes by replacing the minimum number of its elements, which in turn leads to a decrease in the degree of unification and, consequently, to significant production costs in the manufacture of the lighting system as a whole.

And finally, the last, but no less important drawback of these technical solutions is the high thermal loading of all structural elements, including the lens, due to the use of relatively high power light sources - 35W, 55W in its design, which determines the need for its manufacture from relatively expensive and heavy glass ( avoiding the use of cheap and easy to process plastics), which not only increases the complexity of manufacturing such lighting devices in general and its mass, but also leads to additional fuel consumption of the vehicle.

Also known is the design of a light device (vehicle headlights) (see Italian Patent IT 1285998, class B 60 Q 11.26.1996), which implements another method for generating a light beam, including the concentration of light source radiation at the input end of the fiber-optic converter image with the formation of the zone of maximum illumination, the transformation of the cross section of the light beam of concentrated radiation of the light source at the input end of the fiber-optic image converter in the configuration, mirror image the shape of the boundaries of the illumination mode chosen for the implementation at the output end of the fiber-optic image converter, and the projection formed on the output end of the image by projecting the lens onto the illuminated surface.

The design of such a light device contains an ellipsoid axisymmetric reflector, a light source with a filament placed in the region of one of the focuses of the reflector, a fiber-optic image converter, made in the form of a fococouple coupled to an additional image converter mounted on a mounting flange, and a condenser lens, the input end face of the focus of the fiber-optic image converter facing the reflector is located in the region of the second focus of the reflector and has the form of a circle the scattering image of the filament body formed by the reflector in its second focal plane, and the output end of the fiber-optic converter directed to the condenser lens has a shape that matches the light distribution configuration of the light device, while the filament body of the light source is shifted along the optical axis of the reflector in the input direction the end face of the fiber-optic converter, the area of which (Sout) is connected with the maximum area of the focon (Sph) by the ratio Sph = (1 ... 1.3) Sout, and the output end face of the fiber-optic The static converter is made in the form of a concave cylinder.

This technical solution allows you to get rid of a number of disadvantages inherent in the traditional designs of projector-type lighting fixtures, as discussed earlier.

Since radiation leaves each point at the output of the fiber-optic transducer within the same angles due to the aperture number of the fiber used in the transducer, radiation will arrive at one point of the input plane of the lens at different angles, and therefore, being mixed upon refraction, in the lens on it the output will not be observed decomposition of light in the spectral components.

Owing to the same circumstances, the black-and-white border of the light distribution created by such a light device can be scattered to the necessary degree, which largely depends on the parameters of the fiber used.

It is not difficult to see that in this case different light distribution, i.e. the light distribution of different lighting modes is realized only by replacing fiber-optic converters, in which the configuration of the output ends determines the shape of the light distribution corresponding to the given mode with the same design versions of the remaining elements of the light-optical circuit. Therefore, the degree of unification of the designs of lighting devices for various purposes in this case will be very high, which in turn contributes to a significant reduction in the complexity of manufacturing while expanding the range of products.

This method of forming the light beam of the light device and the design that implements it also make it possible to use the light flux of the light source to a greater extent, because it does not have a screen that covers a significant part of the light flux from the bottom of the reflector.

In this case, the radiation of the light source is also used to a greater extent at angles close to the optical axis of the reflector, i.e. within the solid angle formed by the region of the position of the filament body and the output aperture of the fiber-optic converter.

The use of a fiber-optic converter as a screen can also significantly reduce the temperature load on the condenser lens to (50 ... 60) ° C, which in turn determines the possibility of using relatively cheap and lightweight plastic lenses in such structures. Nevertheless, a significant thermal load of the structure is preserved due to the use of ineffective light sources of relatively high power, since in this constructive variant only its redistribution occurs, namely, the glass fiber-optic image converter, heating up when the radiation of the light source is heat-affected, first accumulates this heat due to low thermal conductivity, but then gives it to the adjacent structural elements of the lighting device, which should be l are made of materials with high heat capacity and thermal conductivity.

In addition, when the position of the filament body is shifted towards the input end of the fiber-optic image converter, the area and diameter of the filament image in the second focal plane of the axisymmetric ellipsoid reflector will increase, which in itself contributes to an increase in the input aperture angle of the system, and therefore and the utilization coefficient of the light flux of the light source, but the losses due to an increase in the angle of coverage of the reflector, due to sheniem angles at which the formation of a considerable part of the body in the second filament image focal plane of the reflector.

Moreover, when the ratio Sph / Sout> 1 is fulfilled, where Sph is the area of the input end of the fiber-optic image converter and Sout is the area of the output end of the fiber-optic image converter, the fiber-optic image converter will work as a reducing lens, and therefore the illumination of the central zone of the image of the filament body at the output end of the fiber-optic image converter and the lighting characteristics of the light device as a whole will increase.

However, the main drawback is the limitation of the angle of coverage, and, consequently, the coefficient of use of the light flux of the light source at sufficiently small (40 ... 60) mm values of the diameter of the output projection lens of the diffuser, which is the main requirement for modern light devices, for example, cars due to the desire to improve their aerodynamic characteristics, it remains in this embodiment.

The main reason for limiting the angle of coverage of the reflector and, as a consequence of the relatively low efficiency of using the light flux of the light source, is the limited input aperture angle of the projecting lens that does not exceed in real designs (2φ = 70 °), with a lens diameter of 60 mm and the size of the output end of the fiber-optic converter (21 × 5) mm, which virtually eliminates the use of an ellipsoid reflector with a coverage angle exceeding (90 ... 110) ° at an acceptable reflector depth of (60 ... 70) mm, since this leads to an increase in a the angle of exit of radiation from the reflector to values exceeding (2φ = 70 °), and therefore to meaningless losses of light energy in the fiber material, since all the rays entering the fiber-optic converter at angles exceeding its aperture angle will not exit from the converter.

In addition, this method of forming the light beam of a light device has another significant drawback that reduces the efficiency of the created lighting in the low beam and fog modes, which is manifested in a distortion of the ratio of the lighting characteristics in the normalized light distribution regions, which is due to the lack of an unambiguous relationship between the positions (coordinates ) the inputs of the fibers located on the input side of the fiber-optic converter, and their outputs are located mi at the output end of the fiber optic image converter. Most often, the fibers, the inputs of which are located in the center of the scattering circle of the image of a filament body formed by an axisymmetric ellipsoid in the second focus, have outputs located in the central zone of the figure defining the shape of the output end of the fiber-optic image converter, which determines the central position of the region with the maximum values of the lighting characteristics in asymmetric dimming "dipped beam", in which the area of maximum illumination should be to the right and above central than the actually generated light distribution efficiency decreases.

Another reason for the decrease in efficiency is the loss of luminous flux from a part of the filament body, which is located beyond the focal plane from the side of the neck of the reflector, since the angles of incidence of this part of the light beam, concentrated by the zone of the ellipsoid reflector on both sides of its minor axis, will exceed the optimal aperture angle of the used optical fiber .

It should be noted one more significant drawback of this method of forming a light beam of a light device and its design - the need to perform a rather complex shape of a fiber-optic image converter in the form of a conjugation of the focon and the fiber-optic image converter itself, which is primarily due to significant values of the angles of incidence of the reflected peripheral zones of the ellipsoid reflector of the light beam, which can only partially compensate for the spheres cal shape input end focon. Another reason for the complication of the design of the fiber-optic image converter is the rather large length of the filament body of standard lamps (4.5 ... 5.5) mm with a diameter (1.2 ... 1.5) mm, the image of which is in the second focus of the ellipsoid represents a circle with a diameter of (14 ... 18) mm, an area of (153 ... 254) mm ² , while since Sph = (1 ... 1.3) Sout, the area of the output end of the fiber-optic image converter reaches values (195 ... 254) mm ² , and since the amount of scattering of the light beam in the vertical plane by light devices, for example vehicles does not exceed (10 ... 15) °, then the vertical size of the output end will be small - (8 ... 12) mm, which with a large area of the output end leads to its significant width (28 ... 30) mm . This circumstance, with the optimal aperture number of the used optical fiber equal to 0.5, corresponding to an aperture angle of 35 °, to cover the entire luminous flux emerging from the output end of the fiber-optic image converter, it requires increasing the diameter of the condenser lens to (65 ... 70) mm, and to ensure a standard scattering angle of light devices in the horizontal plane equal to (15 ... 20) °, increase the focal length to (40 ... 50) mm, which results in an unjustified complication of the technology of their manufacture Lenia, increase in size, weight and cost of the product.

The objective of the proposed solution is to improve the lighting characteristics of the light device and reduce its power consumption due to a more complete and efficient use of the light flux of the light source, as well as simplifying the design of one of its most complex elements - a fiber-optic image converter - while reducing its size and dimensions of the light device as a whole.

The problem is realized due to the fact that the method of forming a light beam of a light device includes: concentration of radiation of a light source at the input end of a fiber-optic image converter with formation of a zone of maximum illumination, transformation of the cross-sectional configuration of a light beam of concentrated radiation of a light source at an input end of a fiber-optic converter image in the configuration corresponding to the shape of the borders of the output mode selected for the implementation of the lighting end of the fiber optic image converter, and the projection formed on the output end of the image projecting lens for illuminating the object, the emission concentration is carried out separately for the individual channels.

In this case, the light source is made in the form of at least two LED modules located at an angle to each other, on each of which a radiation concentrator is mounted, made in the form of a converter of the radiation angle of the corresponding LED into a converging and diverging light beam directed to the input end of the fiber-optic image converter so that the optical axis of the diverging light beam intersects the optical axis of the fiber-optic image converter in the input plane tsa, and the focal point of the converging light beam was located at the input end of the fiber-optic image converter in the region where the inputs of individual light fibers have outputs at the output end of the fiber-optic image converter in a region that coincides in angular position with the position of the zone of maximum illumination created by the light distribution device.

Since the number of LEDs and angle converters used for their radiation, as well as the ratio of their types will depend on the power of the LEDs and the requirements for the created light distribution, to ensure the effective use of the proposed method of forming a light beam of almost any given light distribution for any set of LEDs and types of angle converter conditions - the limiting values of the angles of incidence of the extreme rays of the total light beam from all converters and forming an image at the input end of the fiber optic image converter to the input end of the plane should be less than or equal to the aperture angle of fiber used.

The method consists in concentrating the radiation of the light source at the input end of the fiber-optic image converter with the formation of a zone of maximum illumination, transforming the cross-sectional configuration of the light beam of the concentrated radiation of the light source at the input end of the fiber-optic image converter into a configuration corresponding to the shape of the boundaries selected for implementing the lighting mode on the output end of the fiber optic image converter and the projection formed on the output bottom of the image projecting lens onto the illuminated object. In this case, the radiation concentration at the input end of the fiber-optic image converter is carried out separately on separate channels by the corresponding light sources with the formation of radiation beams in the channels. A converging beam is formed in one (their) channel (s), and a diverging beam in the other (them). Or, in all channels, both a converging beam and a diverging beam are simultaneously formed. Or in all channels only a converging beam is simultaneously formed.

The device of the light device for generating the light beam contains a light source, a radiation concentrator of a light source, a fiber optic image converter mounted on a mounting flange, and a condenser lens, the input end face of the fiber optic image converter being located in the focus area of the radiation concentrator and has a shape and geometric the dimensions of the cross section of the light beam emerging from the concentrator formed by a plane perpendicular to the optical axis of the light device, passing through the aforementioned input end face, and the output end of the fiber-optic converter directed to the condenser lens is installed in its focal plane and has the shape of the end face inverse to the shape created by the light distribution device. In this case, the light source is made in the form of at least two LED modules arranged at an angle to each other, on one of which a radiation concentrator is mounted, made in the form of a converter of the radiation angle of the corresponding LED into a converging light beam, and on the other, a radiation concentrator, made in the form of a converter of the angle of radiation into a diverging light beam, directed to the input end of the fiber-optic image converter so that the optical axis of the diverging light beam crossed the optical axis of the fiber-optic image converter in the plane of the input end face, and the focal point of the converging light beam was located on the input end of the fiber-optic image converter in the region where the inputs of the individual light fibers have outputs at the output end of the fiber-optic image converter in the region mirroring in angular position with the position of the zone of maximum illumination created by the light distribution device.

Another embodiment of the light beam forming device comprises a light source, a light source radiation concentrator, a fiber optic image converter mounted on a mounting flange, and a condenser lens, the input end of the fiber optic image converter being located in the focus area of the radiation concentrator and has the shape and the geometric dimensions of the cross section of the light beam emerging from the concentrator formed by a plane perpendicular to the optical axis of the light pa extending through said input end and output end of the fiber optic transmitter directed to the condenser lens is mounted in its focal plane and has the shape of the end face opposite to the shape of light distribution generated by the light device. In this case, the light source is made in the form of at least two LED modules, on each of which a radiation concentrator is mounted, made in the form of a transducer for the angle of emission of the LED, each of which has a structure that produces converging and diverging parts of the light beam directed towards the input end fiber-optic image converter so that the focal point of the converging light beam is located at the input end of the fiber-optic image converter in the region where Second inputs of individual light fibers have exits at the output end of the fiber optic image converter in an area coinciding in mirror angular position with the position of maximum illumination zone light distribution generated by the light device.

Another embodiment of a light device for generating a light beam comprises a light source, a light source radiation concentrator, a fiber optic image converter mounted on a mounting flange, and a condenser lens, the input end face of the fiber optic image converter being located in the focus area of the radiation concentrator and has the shape and the geometric dimensions of the cross section of the light beam emerging from the concentrator formed by a plane perpendicular to the optical axis of the light device, pass yaschey through said input end and output end of the fiber optic transmitter directed to the condenser lens is mounted in its focal plane and has the shape of the end face opposite to the shape of light distribution generated by the light device. In this case, the light source is made in the form of at least two LED modules, on each of which a radiation concentrator is mounted, made in the form of a converter of the angle of emission of the LED into a converging light beam, each directed to the input end of the fiber-optic image converter so that the focal the point of the converging light beam of one of the radiation angle converters was located at the input end of the fiber-optic image converter in the region at which the inputs of individual light fibers have outputs at the output end of the fiber-optic image converter in a region that coincides in angular position with the position of the zone of maximum illumination created by the light distribution device, and the focal point of the converging light beam of another radiation angle transducer is located so that its section is a plane containing the input the end of the fiber-optic image converter, coincided in area and configuration with the mentioned input end of the fiber-optic matic image converter.

Also, during the rays between the converters of the angle of emission of the LEDs and the input end of the fiber-optic image converter, a flat mirror can be installed at an angle of 45 ° to the optical axis of the light device.

The fiber optic image converter can be made in the form of an extended flexible fiber optic bundle.

Also, the focal points of two converging light beams can be located in different regions of the input end of the fiber-optic image converter. Focal points of converging two light beams can be conjugated.

The position of the focal point of the converging light beam may be located at a distance from the input end of the fiber-optic image converter.

The light source can also be made in the form of at least one set including three LED modules, one of which has red light, the other has blue, the third has green.

LED modules can be connected to a power source with the possibility of switching their work during the implementation of external influences.

Also, LED modules with converters of the angle of their radiation can be installed with the possibility of movement relative to the input end of the fiber-optic converter during external exposure.

The proposed method and design of the light device can significantly improve the lighting characteristics of any of the selected lighting modes while reducing the power consumed by the light device and simplifying the design by reducing losses by matching the aperture angles of the input of the optical fiber used in the fiber-optic image converter and the angles of incidence of concentrated radiation from each channel of an energy-intensive light source - LED, also matching the position of the maxi zones cial illumination angle generated by the transducers with radiation convergent light beam on the input and output end of the fiber optic image converter, with the position of this zone in the light distribution generated by the light device.

In addition, the inventive method of forming a light beam and the variants of its design make it possible to realize any possible lighting modes without additional fixtures and devices due to variation of the set (type, quantity, nature of installation) of angle converters used in the design of lighting devices on each channel of the light source varying degrees of concentration.

Along with the above advantages, the proposed technical solution allows to significantly reduce the depth of the light device due to the use of a refractive element installed in the course of the rays between the radiation concentrators and the input end of the fiber-optic image converter due to the use of a refractive element. The same effect can be achieved by using an extended flexible fiber optic bundle bent at an angle necessary for layout as a fiber-optic image converter.

The applicant is not aware of the use of the distinguishing features of the proposed technical solution in another set of distinctive features.

The invention has novelty and inventive step.

A method of forming a light beam of a vehicle light device is implemented (see FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20) as follows.

The radiation from the light source 2, a set of at least two LEDs 3 and 4 is concentrated through separate channels using angle converters 5 and 6 of the corresponding LEDs 3 and 4 with different degrees of concentration of their radiation simultaneously for each channel at the input end 8 of the fiber optical image converter 7, with the formation of a zone of maximum illumination, at least one angle Converter 6 with a converging light beam 6 'and the formation of a bright zone, equal in area and configuration of the area and conf guration input end 8 (see FIG. 2) of fiber-optic transducer 7, concentrated radiation from the LED 3 through the inverter 5 with a divergent angle of the light beam 5 '. Moreover, since the position and design of the angle converters 5 and 6 provide the angles of incidence Ψ of all the rays of the radiation emitted from them, at the input end 8 equal to or less than the aperture angle of the input α (see Fig. 1) used in the fiber-optic image converter 7, of an optical fiber, all radiation incident on the input end 8 will pass into the fiber-optic image converter 7. Then, the fiber-optic image converter 7 transforms the configuration of the cross section of the light beam centered radiation at its input end face 8 into a configuration that is mirror-like to the shape of the boundaries of a given light beam at the output end 9 (see FIG. 2b, 7b, 9b, 11c, 16b).

Moreover, since the position of the zone of maximum illumination corresponds to region 16 at the input end 8 (see Fig. 2a) of the optical fiber image converter 7, in which the inputs of the individual fibers 17 (see Fig. 2) have outputs 18 occupying the output end 9 position mirroring the position of region 19 (see FIG. 3) with the maximum value of the lighting performance created by the light distribution device, then as a result of transformation by the fiber-optic converter 7 of the image formed on the input the bottom end 8, in the image formed at its exit end 9, on the latter light distribution will be formed with a configuration mirror predetermined light distribution of the light unit. The resulting image is projected by the lens 11 onto the surface of the object. When projecting, the image is flipped in both planes, which allows you to form the necessary light distribution on the surface of the object with a given border configuration.

A method of forming a light beam of a light device (see figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 ) is carried out using a device containing a housing 1 with a light source 2 installed in it, made in the form of a set of at least two LEDs 3 and 4 placed at an angle to each other, converters 5 and 6 of the radiation angle of the LEDs 3 mounted on them and 4, one of which, for example 3, has a diverging beam 5 'at the output, and the other 4 with an angle converter 6 converges 6', a fiber-optic image converter 7 s the front 8 and output 9 ends mounted on the mounting flange 10, and a condenser projection lens 11. In this case, the input end 8 of the fiber-optic converter 7 has a cross-sectional shape of the diverging beam 5 'of the angle converter 5 (see Fig. 2a) with a plane 12 perpendicular optical axis 13, and is equal in area to it, and the output end 9 has a shape that mirrors the shape of the boundaries created by the light distribution device (see figb, 7b, 9b, 11c, 16b) and is located in the region of the focal plane 14 of the condenser projection lens 11. While the focal point 15 of the transducer of the angle of radiation 6 with a converging beam is (see figa) at the input end 8 fiber-optic image Converter 7 in the region 16, in which the inputs of the individual fibers 17 have outputs 18 (see fig.2b), occupying the output end 9 position, mirroring the position of the region 19 (see Fig.3), with a maximum value lighting characteristics of a light created by a light device distribution.

Given that (see Fig. 4), the radiation angle converter 20 can simultaneously form two parts of the light beam, one of which converges 5, 6, and the other divergent 21, then the design in this case will contain at least two LED modules 4 and 3, on each of which a radiation concentrator is mounted, made in the form of a radiation angle converter 20 of LEDs 3 and 4, each of which has a structure containing converging and diverging parts of the light beam directed toward the input end 8 of the fiber optic of the image converter 7 so that the focal point 15 of the converging light beams 5 and 6 is located at the input end 8 of the optical fiber image converter 7 in region 16, in which the inputs of the individual optical fibers 17 have outputs 18 at the output end 9 of the optical fiber converter image 7 in the area 18, which coincides in angular position with the position of the zone 19 of maximum illumination created by the light distribution device.

In some cases, for example, when implementing the "low beam" mode of a car headlight, the light distribution of which has at least two zones with a maximum value of the lighting performance, the design (see Fig. 6, 7, 7a, 7b, 8) may contain at least one additional LED 22 and a transducer of the angle of its radiation 23 into a converging light beam 22 ', located so that its focal point 24 is located at the input end 8 (see Fig. 7a) of the fiber-optic converter 7 in region 25 which has individual fibers 26 hav e inputs 27 and their outputs 28 (see. 7b) occupy at the output end 9 position corresponding to position the mirror portion 29 (see. Figure 8) with a second maximal value of lighting characteristics created by the light unit light distribution. In this case, the focal point 15 of the converging light beam 6 'from the radiation converter 6 of the LED 4 is located at the input end 8 (see Fig. 7a) of the fiber-optic converter 7 in the region 30, in which the individual light fibers 31 have inputs 32 and their outputs 33 (see Fig. 7b) occupy at the output end 9 a position mirroring the position of region 34 (see Fig. 8), with a first maximum value of the lighting characteristic.

In those cases when it is necessary to form the light distribution of a light device with a very high value of the lighting performance in any direction, for example, a "spotlight" with a significant level of axial light intensity, its design (see Fig. 9, 9a, 9b, 10) may contain at least one additional LED 22 with an angle converter 23 mounted at an angle to the LED 4 so that the focal points 15 and 24 of the converging light beams 6 'and 23' emerging from the angle converters 6 and 23 are mated to inlet end 8 (s 9, 9a) of the fiber-optic image converter 7 in the region 35, in which the individual fibers 36 have inputs 37, and their outputs 38 (see Fig. 9b) occupy a position at the output end 9 that is mirror image corresponding to the position of the region 39 (see figure 10), with a maximum value of the lighting characteristics created by the light distribution device.

In another embodiment, namely, in those cases where the region of maximum values of the lighting characteristics occupies a significant area in the light distribution created by the light device, as, for example, when implementing the high beam mode of a car headlight, the light device may differ from the design shown in Fig.9, only the fact (see Fig.11, 11a, 11b, 11c, 12) that the focal points 15 and 24 of the converging beams 6 'and 23' of the angle converters 6 and 23 of the LEDs 4 and 22 are located behind the plane of the input end 8 (s . 11) of the fiber optic image converter 7 or to her by the value "S" (see. 11a).

If it is necessary to realize the light distribution of a light device with a relatively uniform light distribution field, its design, in contrast to the previously described, contains (see Fig. 13) at least two LEDs 3 and 40 with angle converters 5 and 41 mounted on them at an angle to each other their radiation into the diverging beam 5 'and 41' is significantly smaller than the angle of emission of the LEDs 3 and 40.

Since the longitudinal arrangement of all the elements of the light-optical circuit in the design leads to an increase in the longitudinal dimension, in some cases, its installation can be complicated.

The elimination of this disadvantage is possible in the design shown in Fig.14. This design, in contrast to the previously considered, contains a flat mirror 42 installed between the angle converters 5 and 6 and the input end 8 of the fiber-optic image converter 7 at an angle of 45 ° to the plane of the input end 8 of the fiber-optic converter 7.

Another constructive solution to this problem, shown in Fig. 15, is also possible. In this case, the fiber-optic image converter 7 is made in the form of an extended flexible bundle 43, in which the input end 8 is placed at the required angle (β) to the optical axis 13 of the light device, and the output end 9 of the necessary configuration to create the selected light distribution of the light device is installed opposite projection lens 11.

When generating light beams with different spectral characteristics, the light device contains at least one set including at least two LED modules with different radiation wavelengths.

For example, to implement a vehicle lighting system with an anti-glare effect, the light source 2 can be made (see Fig. 16, 17) from sets comprising LED modules 44 with an infrared spectrum and white LEDs 45, while the LED modules 44 with an infrared spectrum of radiation with the corresponding transducers of the angle of radiation 46 is set relative to the input end of the fiber-optic transducer so that the concentrated radiation 46 'falls on it 16, the white light-emitting diode modules 45 with the corresponding converters 47 of the radiation angle so as to concentrate the luminous flux 47 'on the left side of the input end 8, the position of which on the output end 9 of the fiber-optic image converter 7 will correspond to that indicated on figb from infrared radiation 46 "on the left, and from visible white light 47" on the right. To visualize the total light distribution 48 (see Fig. 17), in which infrared radiation fills the left zone 49 of the field 48, and the visible light - the right zone 50 of the field 48, a camera 51 is connected to the information processing unit 52 and a display 53.

To implement the construction of the traffic light shown in Fig. 18, at least one set will be required comprising LED modules 54, 55, 56 with a wavelength of radiation of red 54, yellow 55 and green 56, with corresponding angle converters 57, 58, 59 connected to the power source through the corresponding relays.

To obtain a light device emitting white light, the same light-optical circuit shown in Fig. 18 can be used, but in this case the LED modules 54, 55, 56 must have a radiation wavelength of 54 - red, 55 - blue and 56 - green .

To achieve more complex spectral composition of light beams, for example, to illuminate works of art, especially painting (see Fig. 19, 19a), the kit must include combinations of LED modules 60, 61, 62 with radiation of different wavelengths, for example modules 60 with radiation white light, 61 - yellow, 62 - blue modules and providing a given color temperature of the light beam.

If necessary, change the nature of light distribution, i.e. settings of the light device for optimal perception of the object, LED modules 60, 61, 62 (see Fig. 19) with angle converters 63, 64, 65 of their radiation are mounted with the possibility of movement relative to the input end 8 of the fiber-optic converter 7, for example, on the petals 66 a flexible elastic membrane 67 mounted on a fixed support 68, on which the adjusting elements 69 are placed.

In cases where it is necessary to discretely change the values of the output parameters of the lighting characteristics, the LED modules 60, 61, 62 are connected to the power source 70 through the switch 71, as shown in Fig.20.

The light device operates as follows (see figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20) .

When the light device is turned on, both LEDs 3 and 4 light up. The radiation from LED 3 in the angle Ω is transmitted to the input of the angle converter 5, and the radiation of LED 4 to the input of the angle converter 6. At angle converter 5, the radiation from LED 3 is transformed into a divergent beam 5 with a smaller scattering angle, due to which the radiation is concentrated in the output solid angle ω and falls on the input end 8 of the fiber-optic image converter 7. Since the configuration of the input end 8 of the fiber-optic converter 7 has t is the shape of the cross section of the beam 5 ', which emerges from the angle 5 transducer by plane 12 perpendicular to the optical axis 13 of the light device, and is equal to this cross-sectional area, and the incidence angles φ of the extreme rays of the solid angle ω are less than or equal to the aperture angle α of the fiber used, all radiation, generated by the LED 3, will pass through the fiber-optic converter 7. Passing through the fiber-optic image converter 7, the radiation will exit through its output end 9, creating a bright luminous zone on it, the configuration of which will be rkalno coincide with boundaries configuration light distribution generated by the light device. At the same time on the transducer of angle 6, the radiation in the angle Ω. LED 4 is transformed into a converging light beam 6 'in a relatively small solid angle γ, due to which a high concentration of radiation generated by LED 4 is reached at its focal point 15, which falls on the input end 8 of the fiber-optic image converter 7 in region 16 (see Fig. 2a), at the inputs of individual fibers 17, the outputs of which 18 (see Fig. 2b) occupy the position at the output end 9, which mirrors the position of zone 19 (see Fig. 3) of maximum illumination at the light distribution created by the light device nii. Moreover, since the angle of incidence of the extreme rays forming the solid angle γ at the input end 8 is much smaller than the aperture angles α of the fiber used, all the radiation from the LED 4 concentrated by the angle converter 6 will pass through the fiber-optic image converter 7 and will exit at the output end 9 (figb), where it forms a zone of maximum illumination against the background of the bright zone formed by passing through the fiber-optic image converter 7 the radiation of LED 3. Then, the image formed at the exit nom end 9 of the fiber optic converter 6, the condenser lens 11 is projected on the object (see. Figure 3) by creating a predetermined light distribution with a light device 19 in the area of maximum illumination.

The design variant shown in Figs. 4 and 5 works similarly to that previously discussed with the difference due to the design of the angle converters 20 of the radiation generated by the LED modules 3 and 4, due to which the converging parts 5 and 6 and the diverging parts 21 of the light beams emerging from the angle converters 20 will be coupled at the input end 8 of the fiber-optic converter 7. As a result, concentrated radiation in the region 16 from both LED modules 3 and 4 will fall on the input ends of the individual fibers 17, the outputs of which 18 are occupied the prescribed position at the output end 9 is wrinkled, while the scattered part 21 of the light beams emerging from the angle converters 20 will fill the entire input end 8 with radiation. Then, after the radiation passes through the body of the fiber-optic image converter 7, it will form a light field with a predetermined ratio of illumination relative to the boundaries of the output end 9 of the optical fiber image converter 7. Then, the image formed on the output end 9 of the optical fiber converter 6, it is projected by a condenser lens 11 onto the object, creating a given light distribution with a zone of maximum illumination in the region corresponding to the position of the output ends of the fibers 18 at the output end 9.

Another option (see Fig.6, 7, 7a, 7b, 8) of the design works similarly to that shown earlier, with the only difference being that the light fluxes from the LED 4 and the additional LED 22 are concentrated by converters of the angle 6 and 23 of their radiation into light beams 6 'and 23', served on different areas 30 and 25 (see Fig.6, 7, 7a), respectively, and, passing through the inputs 27 and 32 of the light fibers 26 and 31, will go through their outputs 28 and 33 (see Fig. .7b) at the output end 9, where two zones of maximum illumination will be formed in the regions 28 'and 33' (see Fig. 7b,) occupying a position that is mirrored corresponding to the position of both zones of maximum illumination in the light distribution created by him. Moreover, since the angle of incidence ψ of the extreme rays forming the solid angle γ at the input end 7 is smaller than the aperture angles α of the fiber used, all the radiation from the LEDs 3, 4 and 22, concentrated by the angle converters 5, 6, 23, will pass through the fiber optic the image converter 7 will exit at the output end 9, where a mirror distribution with two zones of maximum illumination will be formed (see Fig. 7b) against the background of the bright zone formed by passing through the fiber-optic image converter tions 7 radiation LEDs 3. Then, the image formed on the output end 9 of the fiber optic transducer 7, the condenser lens 11 is projected to an object, creating a predetermined light distribution with a maximum luminance value in the region 29 and 34.

The design of the light device shown in Fig.9, works in the same way as shown above. The difference lies in the fact that at the input end 8 to the region 35 (see Fig. 9a), in which the individual fibers 36 have inputs 37, and their outputs 38 occupy the position at the output end 9, which mirrors the position of the region 38 '(see figb) with the maximum value of the lighting characteristics created by the light distribution device, the radiation generated by the angle converters 6 and 23 is simultaneously incident. As a result, due to the addition of two streams, the value of the lighting characteristics in the region of inputs 37 of fibers will increase and after passing through the fiber optic image converter 7 will increase its importance in the area 38 '(see FIG. 9b, 10) at the exit end 9 and, consequently, in the area 39 created by light distribution.

The design variant shown in Figs. 11, 11a, 11b, 11c, 12 is similar to that shown previously, but in this case, the light beams 6 'and 23' formed by the angle converters 6 and 23 of the LEDs 4 and 22 intersect the input end 8 (see 11b) over a larger area, which will lead to an increase in the number of fibers 36 of region 35 with entrances 37 through which the combined luminous flux of these beams passes. As a result, the area 38 (see Fig. 9c) increases at the output end 9 and, as a result, its brightness decreases while maintaining the brightness of the rest of the output end 9 formed by passing through the fiber-optic transducer 7 of the beam emerging from the angle transducer 5. Then, after the projection of the output end face by the condenser lens 11 (see Fig. 12), the light distribution of the "high beam" mode is finally formed with a fairly smooth change in the lighting performance from the axis of the light device to its periphery.

When operating the option that provides uniform light distribution (see Fig. 13), both diverging beams 5 'and 41' coming out of the angle converters 5 and 41 of the radiation of LEDs 3 and 40, falling on the input end 8 of the fiber-optic image converter 7, will be filled radiation the entire plane of the input end 8 of the fiber-optic Converter 7, passing through which, the radiation will form at the output end 9 a bright area with relatively uniform light distribution, with a border configuration mirror-matching. The projection of this image by the condenser lens 11 will finally form a predetermined light distribution to the lighting object.

The light-optical circuit shown in Fig. 14 works similarly to the previous ones, but the difference is that the light beams formed by the angle converters 5 and 6 of the LEDs used in the course of refract on the mirror 42 and fall on the input end 8 of the fiber-optic converter 7 under the angles provided for by the operability of the structure. As a result, with the same lighting effect, the design of the light device is shorter.

A similar effect is ensured when the constructive variant shown in Fig. 15 is used, in which the radiation incident on the input end 8 passes to its output end 9 along a lengthy fiber-optic image converter 43 bent at the angle necessary for the arrangement, thereby reducing depth of the light fixture.

The operation of a light device that allows you to change the spectral composition of the radiation of the output light beam is shown in Fig.16, 16A, 16B, 17.

When the vehicle’s anti-glare headlight is realized, after turning on the power source, the set of LED modules 44 and 45 is turned on. The radiation from the infrared module 44 is concentrated on the right side of the input end 8 of the fiber-optic image converter 7, and the radiation from the LED module 45 generating white light radiation 47 'to the left side of the input end 8 of the fiber-optic image converter 7 (see Fig. 16a), given that after the radiation has passed through the fiber-optic To the image converter 7, concentrated infrared radiation 46 "will fill the left side of the output end 9 (see Fig.16b), and radiation 47" from the white light module 45 the right side of the output end 9 (see Fig.16b), then after the projection is filled with radiation from both light modules 44 and 45 of the output end 9 with lens 11 we obtain a light distribution in which the right side will be illuminated by radiation 50 of the visible spectrum, and the left (side of oncoming traffic) radiation 49 of the infrared range, the visualization of which can be obtained Curved using standard methods, i.e. when using a camera 51, an information processing unit 52, and a display 53.

As a result, the vehicle headlamp built on this principle will make it possible, when using the number of such sets necessary to create standard lighting characteristics, to provide reliable illumination of the traffic lane in front of the vehicle and to avoid dazzling oncoming vehicles.

In the case when it is necessary to obtain light beams with different spectral characteristics at the output of one light device, for example, a traffic light (see Fig. 18), which must alternately generate light beams of the red, yellow and green radiation spectrum

In the required sequence through the relay, one LED module with the same radiation wavelength of 54 — red, 55 — yellow or 56 — green is turned on from each set.

In an embodiment of a light device generating white light, simultaneously the LED modules 54, 55, 56 of one or more sets containing 54 radiation of red, 55 blue and 56 green are turned on. As a result, after the concentration of radiation from each LED module to the input end 8 of the fiber-optic image converter 7 with the same cross section of concentrated light beams from radiation angle converters 57, 58, 59 at the input end 8, the radiation from all LED modules passes through the fiber optic fibers the image converter 7 will be mixed and come out white with the output end 9.

Another embodiment of the lighting device shown in FIGS. 19, 19a operates similarly to the previous ones, with the only difference being that the LED modules 60, 61, 62 are simultaneously turned on, the radiation of which differs in the emission spectrum and color temperature. Since, after the radiation concentrated by the converters of the angle 63, 64, 65, passes through the body of the fiber-optic image converter 8, it mixes up and forms a light beam at the output end with the necessary radiation spectrum and color temperature.

Another variant of the operation of a light fixture with adjustable light distribution is shown in Figs. 19, 19a, as follows. When the power source is turned on, all LED modules 60, 61, 62 light up, the radiation from them is concentrated depending on the converters of the radiation angle 63, 64, 65 used in the light-optical circuit at the input end 8 of the fiber-optic image converter 7, passing through which creates at its output end 9 distribution of the light flux with the corresponding lighting characteristics and configuration, determined by the shape of the output end 9. The projection of this image by the lens 11 finally completes the process of forming tions of the light beam on the object.

If necessary, change the light distribution pattern within the limits determined by the output end 9 at the maximum energy characteristics of the LED modules 60, 61, 62, by turning the adjusting elements 69 (screws), acting due to their movement relative to the support 68 on the flexible element 66 (lobe) of the membrane 67 s the LED modules 60, 61, 62 and radiation angle converters 63, 64, 65 mounted on it, change the position of the light beams 63 ', 64', 65 'concentrated by them relative to the input end 8 of the fiber optic of the image developing device 7 until the required character of light distribution is formed at its input end face 8, and hence at the object.

The operation of a light device with an adjustable light distribution pattern shown in Figs. 19, 19a, 20 is carried out as follows. When you turn on the power source 70, the current passes through the switch 71 through a circuit that does not change its value. As a result, the rated current and voltage are supplied to the LED modules 60, 61, 62 and all the LED modules light up. The radiation from them is concentrated depending on the radiation angle converters 63, 64, 65 used in the optical scheme at the input end 8, the fiber-optic image converter 7, passing through which creates a light flux distribution at its output end 9 with the corresponding lighting characteristics and configuration, the determined shape of the output end 9. The projection of the image of the output end 9 by the lens 11 finally completes the process of forming the light beam on the object.

If it is necessary to change the illumination level at the object without changing the illumination gradient in the light distribution field, the switch 71 is switched to a position in which the current passes through a circuit limiting its value to a predetermined value on all LED modules 60, 61, 62.

In the case when it is necessary to change the nature of light distribution, the switch is switched to a position in which the magnitude of the current passing through the circuit is changed, which ensures the operation of LED modules selected for realizing a given light distribution, for example 60, 61.

Thus, the proposed method of forming a light beam of a light device and the design options that implement it can significantly improve the characteristics of the created light distribution, reduce its dimensions, reduce weight and power consumption.
