Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to an optical component, a vehicle lamp and a vehicle. Background Art

[0002] With the rapid development of automobile lighting technology, vehicle users have higher and higher requirements for the appearance of headlights, and the demand for diversification and miniaturization of headlights is becoming more and more urgent. LEDs are increasingly widely used in headlights due to their small luminous area, high light energy utilization rate, and good design freedom. As the requirements for the appearance of lamps become more and more stringent, the limited light distribution space becomes more and more obvious. How to reduce the size and weight of lamps has become an urgent problem to be solved. Utility Model Content

[0003] The utility model provides an optical component, a vehicle lamp and a vehicle.

[0004] The optical component of the embodiment of the present application includes a light guide, a light source and a reflector. The light source is used to emit light. The reflector is integrally formed with the light guide. The reflector is used to reflect the light from the light source to the light guide so that the light guide can export the light.

[0005] In the optical assembly of the embodiment of the present application, the light from the light source is reflected to the light guide by the reflector, so that the distance from the light source to the light guide can be increased, and the size and weight of the light guide can be reduced while achieving light uniformity, thereby reducing the production cost of the optical assembly. In addition, the reflector and the light guide are integrally formed, which can reduce the assembly error of the reflector and the light guide, and improve the precision of the components of the optical assembly.

[0006] In some embodiments, the light guide includes a light incident surface facing the reflector, and a first light homogenizing structure is formed on the light incident surface.

[0007] In this way, the first light homogenization structure can distribute the light entering the light guide member so that the light is uniformly and parallelly guided out through the inside of the thick-walled member, thereby improving the optical efficiency and avoiding the problem of uneven local brightness.

[0008] In some embodiments, the first light homogenization structure includes textures formed on the light incident surface.

[0009] In this way, by forming patterns on the light incident surface, the transparency of the thick-walled component can be reduced, making it difficult to see the inside through the thick-walled component from the outside, thereby improving the uniformity of light.

[0010] In some embodiments, the light guide includes a light emitting surface opposite to the light incident surface, and a second light homogenizing structure is formed on the light emitting surface.

[0011] In this way, the second light homogenizing structure can reflect the light and improve the uniformity of the light emitted by the light guide member.

[0012] In some embodiments, the reflector includes a reflective surface facing toward the light guide, and the reflective surface is a concave surface.

[0013] In this way, the reflective surface can converge and reflect the light from the light source. In addition, the concave surface increases the distance from the light source to the light incident surface, thereby achieving light homogenization and reducing the size and weight of the light guide.

[0014] In some embodiments, the reflective surface is formed with a diffuse reflective structure.

[0015] In this way, the diffuse reflection structure can enhance the diffuse reflection of light on the reflective surface, improve the granularity of light, and improve the uniformity of light.

[0016] In some embodiments, the reflective surface is provided with a reflective film.

[0017] In this way, the reflective film can improve the reflection efficiency of light, thereby increasing the amount of light entering the thick-walled part, improving the utilization rate of light energy, and reducing the loss of light energy.

[0018] In some embodiments, the optical assembly includes a circuit board, which is fixedly connected to a reflector, and the light source is disposed on the circuit board. The circuit board, the light guide and the reflector together define a light guiding space, and the light source is located in the light guiding space.

[0019] In this way, by connecting the circuit board to the light source, the light source can be controlled, and the light of the light source can be transmitted to the light guide member through the light guide space.

[0020] The vehicle lamp according to the embodiment of the present application includes an optical component.

[0021] In the optical assembly of the embodiment of the present application, the light from the light source is reflected to the light guide by the reflector, so that the distance from the light source to the light guide can be increased, and the size and weight of the light guide can be reduced while achieving light uniformity, thereby reducing the production cost of the optical assembly. In addition, the reflector and the light guide are integrally formed, which can reduce the assembly error of the reflector and the light guide, and improve the precision of the components of the optical assembly.

[0022] A vehicle according to an embodiment of the present application includes a vehicle lamp.

[0023] In this way, when the vehicle uses the headlights, the light emitted by the headlights is uniform, which can improve the practicality of the vehicle and enhance the user experience. In addition, the size and weight of the headlights are low, which makes the production cost of the headlights low.

The light source 20 is used to emit light. The reflector 30 is integrally formed with the light guide 10. The reflector 30 is used to reflect the light from the light source 20 to the light guide 10 so that the light guide 10 can export the light.

[0038] In the optical assembly 100 of the embodiment of the present application, the light from the light source 20 is reflected to the light guide 10 by the reflector 30, so that the distance of the light from the light source 20 to the light guide 10 can be increased, and the size and weight of the light guide 10 can be reduced while achieving light uniformity, thereby reducing the production cost of the optical assembly 100. In addition, the reflector 30 and the light guide 10 are integrally formed, which can reduce the assembly error of the reflector 30 and the light guide 10 and improve the precision of the components of the optical assembly 100.

[0039] Specifically, the light guide 10 may be an optical element with a light-guiding function, including but not limited to a thick-walled member. The light guide 10 may be made of a solid light-transmitting material, which can enhance the durability of the light guide 10 itself while ensuring the light penetration. The structure of the light guide 10 may be rhombus-shaped, and the thickness of the light guide 10 gradually decreases along the propagation direction of the light, so that the light can be fully reflected more times in the light guide 10, making the light guided by the light guide 10 more uniform. The thickness of the light guide 10 can be designed according to actual needs.

[0040] The light source 20 may be an LED lamp bead, which has good luminous effect, small size and convenient control. Different optical functions can be achieved by selecting light sources 20 of different powers and colors. The light color of the light source 20 may be any one of red, yellow and white.

[0041] The reflector 30 can be made of milky white non-translucent material, and the reflector 30 and the light guide 10 can be integrally formed by a two-color injection molding process. The reflector 30 can be any optical structure of a concentrator, a Fresnel, and a light guide plate, that is, the reflector 30 can be a concentrator optical structure, or the reflector 30 can be a Fresnel optical structure, or the reflector 30 can be a light guide plate optical structure.

[0042] See also Figure 1 and Figure 2 In some embodiments, the light guide 10 includes a light incident surface 11 facing the reflector 30 , and a first light homogenizing structure 12 is formed on the light incident surface 11 .

[0043] In this way, the first light homogenizing structure 12 can distribute the light entering the light guide member 10 so that the light is uniformly and parallelly guided out through the inside of the thick-walled member, thereby improving the optical efficiency and avoiding the problem of uneven local brightness.

[0044] Specifically, the light incident surface 11 is used to receive the light from the light source 20 after being reflected by the reflector 30. By increasing the area of ​​the light incident surface 11, the efficiency of light entering the light guide 10 can be improved. The shape and size of the light incident surface 11 can be designed according to actual needs. The first light homogenizing structure 12 can be a pattern, and the shape of the pattern can be arbitrarily designed according to actual needs, including but not limited to stepped, striped, serrated, etc., which is not limited in this application.

[0045] In some embodiments, the first light homogenizing structure 12 includes patterns formed on the light incident surface 11 .

[0047] Specifically, fine optical grains may be added to the light incident surface 11 , and the shape and size of the grains may be designed according to actual needs.

[0048] See also Figure 1 and Figure 2 In some embodiments, the light guide 10 includes a light emitting surface 13 opposite to the light incident surface 11 , and a second light homogenizing structure 14 is formed on the light emitting surface 13 .

[0049] In this way, the second light homogenizing structure 14 can reflect the light, thereby improving the uniformity of the light emitted by the light guide member 10 .

[0050] Specifically, the light emitting surface 13 is used to emit light from the light guide 10, and the area of ​​the light emitting surface 13 can be smaller than the area of ​​the light incident surface 11. The second light homogenizing structure 14 can be a pattern, and the shape of the pattern can be arbitrarily designed according to actual needs, including but not limited to stepped, striped, serrated, etc., which is not limited in this application.

[0051] See also Figure 1 In some embodiments, the reflector 30 includes a reflective surface 31 facing the light guide 10, and the reflective surface 31 is a concave surface.

[0052] In this way, the reflective surface 31 can converge and reflect the light from the light source 20. In addition, the concave surface increases the distance of the light from the light source 20 to the light incident surface 11, thereby achieving light homogenization and reducing the size and weight of the light guide 10.

[0053] Specifically, the reflective surface 31 is used to reflect the light from the light source 20 to the light incident surface 11 of the light guide 10, and the light source 20 and the light guide 10 are located on the same side of the reflective surface 31. The reflective surface 31 is a concave surface, which can be understood as the reflective surface 31 arches outward in a direction away from the light guide 10, and the degree of concavity and convexity of the reflective surface 31 can be designed according to actual needs.

[0054] See also Figure 1 and Figure 2 In some embodiments, the reflective surface 31 is formed with a diffuse reflection structure 32 .

[0055] In this way, the diffuse reflection structure 32 can enhance the diffuse reflection of light on the reflection surface 31, improve the granularity of light, and enhance the uniformity of light.

[0057] In some embodiments, the reflective surface 31 is provided with a reflective film.

[0058] In this way, the reflective film can improve the reflection efficiency of light, thereby increasing the amount of light entering the thick-walled part, improving the utilization rate of light energy, and reducing the loss of light energy.

[0059] Specifically, the reflective film may be a metal film layer, and the reflective surface 31 may be processed by aluminum plating to form the reflective film. The area and thickness of the reflective film may be designed according to actual needs.

[0060] See also Figure 3 and Figure 4 In some embodiments, the optical component 100 includes a circuit board 40, which is fixedly connected to the reflector 30. The light source 20 is disposed on the circuit board 40. The circuit board 40, the light guide 10 and the reflector 30 jointly define a light guiding space 21, and the light source 20 is located in the light guiding space 21.

[0061] In this way, by connecting the circuit board 40 to the light source 20 , the light source 20 can be controlled, and the light of the light source 20 can be transmitted to the light guide member 10 through the light guide space 21 .

[0062] Specifically, the circuit board 40 and the reflector 30 can be fixedly connected by fasteners such as screws 50. In some embodiments, the reflector 30 is provided with two positioning pins 33, and the circuit board 40 is formed with two positioning holes 41. The two positioning pins 33 are respectively inserted into the two positioning holes 41 to limit the relative position of the circuit board 40 and the reflector 30. The circuit board 40 and the reflector 30 are formed with four mounting holes 42. Fasteners such as screws 50 are screwed into the mounting holes 42 to fix the circuit board 40 and the reflector 30. The number of light sources 20 can be multiple, for example, three, four, five, six, etc., and multiple light sources 20 can be installed on the circuit board 40 through patches. The light guide space 21 can be a space formed by the circuit board 40, the light incident surface 11 of the light guide 10, and the reflective surface 31 of the reflector 30. By increasing the light guide space 21, the distance from the light source 20 to the light incident surface 11 can be increased, thereby improving the uniformity of the light.

[0063] The vehicle lamp 200 according to the embodiment of the present application includes an optical assembly 100 .

[0064] In the optical assembly 100 of the embodiment of the present application, the light from the light source 20 is reflected to the light guide 10 by the reflector 30, so that the distance of the light from the light source 20 to the light guide 10 can be increased, and the size and weight of the light guide 10 can be reduced while achieving light uniformity, thereby reducing the production cost of the optical assembly 100.
