Description

Technical Field

[0001] The utility model relates to the field of vehicle lamps, in particular to a vehicle lamp with uniform light transmission. Background Art

[0002] With the rapid development of new energy vehicles, the exterior decoration of cars has also received more and more attention. The use of car lights is like eyes to people. The use of car lights is not only directly related to safe driving, but also the shape of car lights will affect the appearance of the whole car. In today's market, the integration of car bumpers and car lights has become a mainstream. Different patterns are designed in the lighting area. On the basis of not adding special processes and complex components, when the lighting system is not turned on, the car bumper presents the body paint effect like a traditional bumper. When the lighting system is turned on, the lighting light penetrates evenly from the carved patterns, which makes the car lighting shape more diversified. However, the carved patterns on the simple PC material cannot meet the requirements of the cutting-edge market. At the same time, a lot of heat will be generated in the existing lighting system process, which is not easy to dissipate and will cause damage to the lighting system.

[0003] In the prior art, a Chinese utility model type patent with a public document number of CN215061813U discloses a light-distributing headlight structure. The utility model, through a combination of LED, thick-walled parts and inner lampshade, and with the cooperation of inner and outer patterned layers, can disperse and distribute light twice, thereby ultimately forming a headlight with uniform optical effect and exquisite appearance. At the same time, through the cooperation of thermal conductive silicone and heat sink, the heat on the LED and circuit board can be quickly transferred to the outside, thereby achieving rapid heat dissipation and cooling of the device, greatly extending the service life of the device. However, the inner patterned layer is fixedly connected and cannot rotate, which reduces the dispersion effect of the light source. After the various structures in the headlight are connected to each other, the space is small and the heat is not easy to dissipate. The heat transfer and heat dissipation effects of the thermal conductive silicone and the heat sink are insufficient, so improvement is needed. Utility Model Content

[0004] The main purpose of the utility model is to provide a vehicle lamp with uniform light transmission, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the exterior mirror of the headlight is made of transparent PC injection molding, and translucent light diffusion ink is sprayed on the inside of the transparent PC, and opaque body paint is sprayed on the outside of the PC sample. The desired pattern is laser engraved on the body paint. In this way, when the light source is not lit, the appearance is the body paint plus the laser engraved pattern. When the light source is lit, the light penetrates evenly from the laser engraved pattern.

[0014] In the utility model, the condenser and the inner lens are separated from each other, so that the heat of the LED lamp head can be easily dissipated outward from the gap between the two, which is convenient for heat extraction.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, a uniformly light-transmitting headlight comprises an LED lamp head 1 and an outer light distribution mirror 13, wherein the LED lamp head 1 is fixedly connected in a condenser 2, a No. 1 mounting frame 4 is fixedly connected to the upper position of the condenser 2, an inner lens 5 is fixedly connected to the No. 1 mounting frame 4, a No. 2 mounting frame 6 is movably installed in the lower position of the condenser 2, the No. 2 mounting frame 6 is fixedly connected to the No. 1 mounting frame 4, a push fan blade 9 is fixedly connected to the side position of the No. 2 mounting frame 6, a connecting rod 3 is arranged between the No. 1 mounting frame 4 and the No. 2 mounting frame 6, and the two ends of the connecting rod 3 are respectively fixedly connected to the No. 1 mounting frame 4 and the No. 2 mounting frame 6, and the center of the air intake cover 10 is fixedly connected to the No. 1 mounting frame 4 and the No. 2 mounting frame 6. A support rod 7 is fixedly connected in position, and the upper end of the support rod 7 is fixedly connected to the condenser 2. The condenser 2 is located between the connecting rods 3. A bearing 8 is movably installed on the support rod 7. The support rod 7 is movably installed with the No. 2 mounting frame 6 through the bearing 8. The bearing 8 is located on the inner side of the No. 2 mounting frame 6. The No. 2 mounting frame 6 rotates through the bearing 8, so that the No. 2 mounting frame 6 is fixedly connected with the No. 1 mounting frame 4, so that the inner lens 5 starts to rotate synchronously, and the rotating inner lens 5 has a better dispersion effect on the LED lamp head 1, so that the light of the LED lamp head 1 is dispersed and passes through the external light distribution mirror 13 to make the light more uniform.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, an air intake hood 10 is fixedly connected to the lower position of the No. 2 mounting frame 6, and a silent fan 12 is fixedly connected inside the air intake hood 10. The LED lamp head 1, the inner lens 5, and the air intake hood 10 are all located at the inner side of the outer light distribution mirror 13. A plurality of exhaust pipes 11 are fixedly connected to the upper position of the air intake hood 10. The exhaust pipes 11 are arranged in an array around the support rod 7. The outlets of the exhaust pipes 11 are located below the push blades 9. The push blades 9 are arranged in an array around the No. 2 mounting frame 6. The inner side of the outer light distribution mirror 13 is sprayed with light diffusion ink, and the outer side of the outer light distribution mirror 13 is sprayed with body paint. The silent fan 12 is used to dissipate the heat of the focusing cover 2 and the LED lamp head 1 in the headlight. Since the focusing cover 2 and the inner lens 5 are separated from each other, the heat can be easily dissipated from the gap between the two, so that the heat dissipation effect of the headlight is better, and the airflow generated by the silent fan 12 drives the blades 9 to provide power for the rotation of the inner lens 5.

[0024] It should be noted that the utility model is a uniformly light-transmitting headlight. The outer light distribution mirror 13 is made of transparent PC material, injection molded, and integrated with the car bumper. Light diffusion ink is sprayed on the inner side of the outer light distribution mirror 13, and body paint is sprayed on the outer side of the outer light distribution mirror 13. Then, a laser pattern is carved on the outer side of the outer light distribution mirror 13. In this way, when the light source is not lit, the appearance is an integrated body paint and laser carved pattern. When the LED lamp head 1 is lit, the silent fan 12 in the air intake cover 10 is started synchronously, and the silent fan 12 discharges the airflow through the exhaust pipe 11. The discharged airflow blows the push fan blade 9, so that the push fan blade 9 drives the second The mounting frame 6 rotates, and the second mounting frame 6 rotates on the support rod 7 through the bearing 8. The second mounting frame 6 is fixedly connected to the first mounting frame 4, so that the first mounting frame 4 and the inner lens 5 rotate synchronously. The rotating inner lens 5 can better disperse the light source of the LED lamp head 1, and then the dispersed light source is transmitted through the patterns of the outer light distribution mirror 13, so that the light is more uniform, and the airflow discharged from the exhaust pipe 11 and the airflow formed by the rotation of the fan blades 9 dissipate the heat for the condenser 2 and the LED lamp head 1 therein. Since the condenser 2 and the inner lens 5 are separated, the heat can be easily lost between the two, thereby making the heat dissipation effect of the car lamp better.
