Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp lighting, in particular to a TIR focusing high beam module and a concentrator. Background Art

[0002] With the development of vehicle lighting technology, high and low beam lens modules are becoming more and more popular. However, the high beam module of the traditional "condenser + single-focus focusing lens" solution is usually longer in the direction of the vehicle body axis and larger in size. The light beam formed by this module will present a circular condenser-shaped light spot image on the surface of the car headlight cover. This problem cannot be solved. At the same time, in order to improve the high beam illumination, the single-focus lens high beam module has a large deflection angle of the non-central condenser light, and the high beam light type is likely to be partially yellow, which is not good for the appearance.

[0003] Therefore, how to improve the lighting effect of vehicle lights is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0004] In view of this, the first object of the utility model is to provide a TIR focusing high beam module to improve the lighting effect of the vehicle lamp;

[0005] The second object of the utility model is to provide a concentrator.

[0006] In order to achieve the above first purpose, the utility model provides the following technical solutions:

[0007] A TIR focusing high beam module comprises a light incident portion and a free-form surface mirror group. The light incident portion comprises a TIR light incident surface and a TIR total reflection free-form surface. The TIR light incident surface is a plane, and light is incident from the TIR light incident surface. The TIR total reflection free-form surface is used to reflect the light. The free-form surface mirror group is the light output end of the TIR focusing high beam module and is used to form a light pattern.

[0008] Optionally, in the above-mentioned TIR focusing high beam module, the free-form surface lens group includes a conjugate free-form surface and a focal line lens, the conjugate free-form surface is connected to the light incident part, and its output surface is a concave surface, and the focal line lens is separately arranged from the conjugate free-form surface.

[0009] Optionally, in the above-mentioned TIR focusing high beam module, the TIR light incident surface is a vertical plane.

[0010] Optionally, in the above-mentioned TIR focusing high beam module, the TIR light incident surface is an inclined plane.

[0011] Optionally, in the above-mentioned TIR focusing high beam module, an LED light source is arranged on the TIR light incident surface.

[0012] The TIR focusing high beam module provided by the utility model, when in use, light is incident from the TIR light incident surface, and is reflected by the TIR total reflection free-form surface, and the TIR total reflection free-form surface plays the role of collecting and focusing light, and the direction of light is changed here, and the light is mirror-bent, thereby realizing the folding of the light path and shortening the length of the TIR focusing high beam module. In this process, the deflection angle of the light is small, and the yellowing of the high beam light type is avoided. Then the light enters the free-form surface mirror group, forms a light type with parallel light in the up and down direction and divergent light in the left and right direction, and emits, thereby improving the lighting effect of the headlight. At the same time, the TIR light incident surface is a plane, which can improve the heat dissipation effect of the TIR focusing high beam module and facilitate processing.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making novel work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "top surface", "bottom surface" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] like Figure 1-Figure 6As shown, the TIR focusing high beam module disclosed in the utility model includes a light input part and a free-form surface mirror group 100, the light input part includes a TIR light input surface 200 and a TIR total reflection free-form surface 300, the TIR light input surface 200 is a plane, the light is incident from the TIR light input surface 200, the TIR total reflection free-form surface 300 is used to reflect the light, and the free-form surface mirror group 100 is the light output end of the TIR focusing high beam module, which is used to form a light pattern. Specifically, the light mapped to the surface of the headlight mask by the TIR total reflection free-form surface 300 is a block-shaped light spot, which has a good visual effect and a good lighting effect. The TIR focusing high beam module provided by the utility model, when in use, light is incident from the TIR light incident surface 200, and is reflected by the TIR total reflection free-form surface 300, and the TIR total reflection free-form surface 300 plays the role of collecting and focusing light, and the direction of light is changed here, and the light is mirror-bent, thereby realizing the folding of the light path and shortening the length of the TIR focusing high beam module. In this process, the deflection angle of the light is small, which avoids the yellowing of the high beam light type. Then the light enters the free-form surface mirror group 100, forms a light type of parallel light in the up and down direction and divergent light in the left and right direction, and emits, thereby improving the lighting effect of the headlight. At the same time, the TIR light incident surface 200 is a plane, which can improve the heat dissipation effect of the TIR focusing high beam module and facilitate processing.

[0028] In order to optimize the above technical solution, the free-form surface lens group 100 includes a conjugate free-form surface 400 and a focal line lens 500. The conjugate free-form surface 400 is connected to the light input part, and its exit surface is a concave surface. The focal line lens 500 is separated from the conjugate free-form surface 400. Specifically, the conjugate free-form surface 400 and the focal line lens 500 match, that is, the focal line of the focal line lens 500 coincides with the virtual focal line of the conjugate free-form surface 400. Specifically, the focus separation of the focal line lens 500 and the conjugate free-form surface can optimize the dispersion problem. Through the focus separation, a light type that is wide on the left and right and narrow on the top and bottom can be directly obtained, without too much optical surface adjustment design, so the brightness uniformity and color uniformity of the formed light spot are better. Further, the two sides of the focal line lens 500 can be uniformly curved, or they can be bent to different degrees with the change of the shape. Specifically, the free-form surface lens group 100 with focus separation can reduce the overall volume of the focal line lens 500 and the TIR focusing high beam module. Therefore, such an arrangement can make the light reflected from the TIR total reflection free-form surface 300, and through the combined action of the focal line lens 500 and the conjugate free-form surface 400 matched therewith, the outgoing light is made parallel light, and a high beam light pattern with excellent brightness and uniformity can be obtained.

[0029] In order to optimize the above technical solution, the TIR light incident surface 200 is a vertical plane. Specifically, the TIR light incident surface 200 is a vertical plane, which can facilitate the processing of the TIR focusing high beam module and facilitate quality control.

[0030] In order to optimize the above technical solution, the TIR light incident surface 200 is an inclined plane. Specifically, the TIR light incident surface 200 is an inclined plane which is conducive to the thermal cycle of the TIR focusing high beam module, and the angle of the PCB board can be freely adjusted to facilitate the co-board with the low beam LED.

[0031] In order to optimize the above technical solution, an LED light source 600 is arranged on the TIR light incident surface 200. Specifically, the LED light source 600 is used to emit light, and the light directly reaches the TIR total reflection free-form surface 300 from the TIR light incident surface 200.

[0032] The utility model also discloses a concentrator, comprising a PCB board and a TIR focusing high beam module as described above, wherein the PCB board is arranged parallel to the TIR light incident surface 200 of the TIR focusing high beam module. Specifically, the angle of the PCB board is adjustable, and the PCB board is arranged parallel to the TIR light incident surface 200 and arranged outside the LED light source 600.

[0033] In order to optimize the above technical solution, the number of TIR focusing high beam modules is one or more. Specifically, by changing the number and arrangement of TIR focusing high beam modules, the shape of the area formed by the light pattern combination can be changed, thereby improving the lighting effect of the headlight. Specifically, the LED light source 600, the TIR light incident surface 200, the TIR total reflection free-form surface 300 and the conjugate free-form surface 400 form an optical path unit, and the TIR focusing high beam module can be formed by splicing and combining one or more optical path units to enhance the intensity of the illumination light.

[0034] Since the above-mentioned TIR focusing high beam module has the above effects, the concentrator included in the TIR focusing high beam module has corresponding effects, which will not be described in detail here.

[0035] The advantages of the utility model are:

[0036] (1) Improved the lighting effect of car lights;

[0037] (2) A high beam pattern with excellent brightness and uniformity can be obtained;

[0038] (3) Good heat dissipation effect and easy processing.
