Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle lamp lighting, and particularly relates to a structure with function multiplexing and a vehicle lamp thereof. Background Technique
[0002] In recent years, with the continuous progress of automobile manufacturing technology, vehicle lamp technology has also developed rapidly. From the initial simple single-source vehicle lamps to modern complex multi-source and matrix LED vehicle lamps, the design of vehicle lamps has been continuously innovated to meet the diverse needs of consumers for lamp shapes. In addition to the lighting function, the appearance of modern vehicle lamps has also received more and more attention. Automobile manufacturers have continuously tried various novel lamp shape designs, aiming to add a more aesthetic visual effect to the vehicle body while ensuring good lighting performance, enhancing the fashion sense and personalized features of the whole vehicle. In order to further improve the practicality and innovation of vehicle lamps, function multiplexing and the lighting appearance effect of multiple light-emitting ports are also the mainstream forms in the current vehicle lamp technology field.
[0003] In traditional projects, after the light rays emitted from the LED pass through a series of acting devices and then exit from the light-emitting surface. To achieve the lighting effect of a multi-functional shared light-emitting port, the existing multiplexing solutions usually share a single PCB board, which will have a problem of function defocus, so the system efficiency is not high. Content of the Utility Model
[0004] In view of this, in order to solve the problems existing in the prior art, the purpose of the utility model is to provide a structure with function multiplexing and a vehicle lamp thereof, which has the effect of sharing a single PCB board for each function, with uniform and efficient light emission without defocus.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A structure with function multiplexing, including: a reflective thick-walled part, a reflector and a circuit board. The reflective thick-walled part and the reflector are respectively arranged on both sides of the circuit board. One end of the reflective thick-walled part is formed with a first reflecting part, and the reflector is formed with a second reflecting part;
[0007] The other end of the reflective thick-walled part is formed with a light-emitting surface, the light-emitting surface faces the second reflecting part, a light guide channel is formed in the reflective thick-walled part, and both ends of the light guide channel are respectively communicated with the light-emitting surface and the first reflecting part.
[0008] The specific technical effect is that by separately arranging the reflective thick-walled member and the reflector on both sides of the circuit board, when the multifunctional LED light-emitting member shares a single PCB board, the light emitted by one function enters through the reflective thick-walled member, and the light emitted by the other function enters the reflective thick-walled member through the reflector. After multiple reflections, total reflections or refractions through the light guide channel, the light exits from the light exit, achieving the effect that the multifunctional LED light-emitting member shares a single PCB board and a single light exit, with uniform and efficient light output without defocusing.
[0009] Further, the reflective thick-walled member includes a total reflection structure, a light guide structure, and a refraction structure. The light guide structure is inclined and arranged between the light exit surface and the second reflection portion. The total reflection structure is inclined and arranged above the light guide structure and faces the first reflection portion. The refraction structure is vertically arranged between the total reflection structure and the first reflection portion, and the lower end of the refraction structure is connected to the upper end of the light guide structure.
[0010] The specific technical effect is that through the cooperation of the total reflection structure, the light guide structure, and the refraction structure, the multifunctional LED light-emitting member shares a single PCB board and a single light exit, with uniform and efficient light output without defocusing. The light of one LED light-emitting member enters the reflective thick-walled member, is reflected by the first reflection portion to the refraction structure and enters the reflective thick-walled member, then is refracted by the refraction structure to the total reflection structure, and then is totally reflected by the total reflection structure to the light guide structure and exits from the light exit surface after being reflected by it. The light of the other LED light-emitting member enters the reflector, is reflected by the second reflection portion to the light guide structure, enters the reflective thick-walled member after being refracted by the light guide structure, and then exits from the light exit surface.
[0011] Further, both the inner surfaces of the first reflection portion and the second reflection portion are aluminized.
[0012] The specific technical effect is that aluminizing the first reflection portion and the second reflection portion aims to increase the reflection efficiency, effectively reflect the light to the light guide structure and the refraction structure, improve the utilization efficiency of light energy, thereby reducing the power consumption of the light source and improving the energy utilization efficiency of the entire vehicle lamp system.
[0013] Further, the projection distances of the total reflection structure and the light guide structure in the horizontal direction are equal.
[0014] The specific technical effect is that with this design, the light passing through the total reflection structure can be reflected to the light guide structure, improving the utilization efficiency of light energy.
[0015] Further, the included angle α between the total reflection structure and the incident light direction ranges from 40° to 50°.
[0016] Further, the light guide structure includes a plurality of refraction surfaces and a plurality of total reflection surfaces, the refraction surfaces and the total reflection surfaces are arranged alternately, the refraction surfaces are arranged parallel to the light exit surface, and the included angle β between the total reflection surfaces and the incident light direction ranges from 40° to 50°.
[0017] The specific technical effect is that: with such an angular design of the refraction surface and the total reflection surface, after the light is reflected from the second reflection part of the reflector, it can efficiently enter the reflective thick-walled part, and then after exiting from the light exit surface, its direction remains unchanged.
[0018] Further, corn kernel patterns or vertical stripe patterns are provided on both the total reflection structure, the light guide structure and the refraction structure.
[0019] Further, corn kernel patterns are provided on the light exit surface.
[0020] Further, an LED light-emitting component is provided on each of the two sides of the circuit board. One of the LED light-emitting components faces the first reflection part, and the other LED light-emitting component faces the second reflection part. The light source color of the LED light-emitting component is one or more of red, white or yellow.
[0021] A vehicle headlight, which includes a structure with function multiplexing as described in any one of the above.
[0022] The beneficial effects of the present utility model are:
[0023] By separately arranging the reflective thick-walled part and the reflector on both sides of the circuit board, when a multi-functional LED light-emitting component shares a single PCB board, the light emitted by one function enters from the reflective thick-walled part, and the light emitted by the other function enters the reflective thick-walled part from the reflector. After multiple reflections, total reflections or refractions through the light guide channel, they are all emitted from the light exit port, achieving the effect that the multi-functional LED light-emitting component shares a single PCB board and a single light exit port, with uniform and efficient light emission without defocusing.

The light of one LED light-emitting part 6 is incident on the reflective thick-walled part 1, reflected by the first reflection part 4 onto the refraction structure 11 and enters the reflective thick-walled part 1, then refracted by the refraction structure 11 onto the total reflection structure 9, and then totally reflected by the total reflection structure 9 onto the light guiding structure 10, and after being reflected by it, exits from the light-emitting surface 8.
