Description

Technical Field

[0001] The utility model belongs to the technical field of automobile lighting, and specifically relates to a light-emitting structure and an integrated diamond three-dimensional effect thick-walled part. Background Art

[0002] With the rapid development of the automotive industry, the design of car lights must not only meet regulatory requirements, but also the needs of vehicle manufacturers to pursue more beautiful, unique, and uniform lighting effects. More and more car manufacturers are pursuing the application of three-dimensional, shining, and highly transparent pattern effects to daytime running lights, position lights, turn signals and other headlights with large luminous surfaces. However, in recent years, the patterns of headlights have been relatively simple, mostly corn kernels, and consumers have become aesthetically fatigued.

[0003] Therefore, some car manufacturers have proposed to use three-dimensional diamond patterns as the outer surface effects of daytime running lights, turn signals, and position lights. The common solution on the market is to make random three-dimensional convex patterns on the outer surface of thick-walled parts. This solution is common in functions such as interactive lights and grille lights that do not need to meet lighting regulations. However, in order to achieve a three-dimensional and dazzling effect, the pattern diffusion direction of the outer surface of the thick-walled parts is random, which cannot meet the regulatory requirements for daytime running lights and other lights with higher central energy requirements. Utility Model Content

[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 light-emitting structure and an integrated diamond three-dimensional effect thick-walled part, which can achieve a diamond three-dimensional shining effect on car lights with higher central energy requirements such as daytime running lights while meeting regulatory requirements, and can improve optical utilization efficiency.

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

[0006] A light emitting structure, comprising: a concentrator, a reflective surface, a thick-walled structure and a light emitting surface;

[0007] The light emitting surface is arranged at the front end of the thick-walled structure, the reflecting surface is arranged at the rear end of the thick-walled structure, the concentrator is arranged at the rear lower end of the thick-walled structure and is arranged directly opposite to the reflecting surface, the cross-section of the reflecting surface is arranged in a parabolic shape, and the reflecting surface has a focus A. The light enters the concentrator and is totally reflected by the reflecting surface and converges at the focus A, and then reaches the light emitting surface through the focus A. The light passes through the light emitting surface and is emitted from the light emitting structure.

[0008] The specific technical effect is: the light passes through the concentrator and is concentrated on the reflective surface and then reflected by the reflective surface to the light emitting surface, which changes the diffusion angle of the light, thereby obtaining a more uniform lighting effect and avoiding the problem of random light diffusion direction in the prior art.

[0009] Furthermore, the concentrator is arranged in a truncated cone structure, which includes a light entrance and a curved side wall. The curved side wall is arranged around the light entrance, and the light entrance faces the reflecting surface. Light enters from the light entrance and is reflected from the curved side wall to the reflecting surface.

[0010] The specific technical effect is that light enters from the light entrance and is reflected by the curved side wall to form collimated parallel light, which hits the reflecting surface.

[0011] Furthermore, the thick-walled structure further includes: an arcuate convex lens, the arcuate convex lens is arranged at the front end of the thick-walled structure, the light-emitting surface is formed on the arcuate convex lens, and the cross-section of the arcuate convex lens is arranged in a parabolic shape.

[0012] The specific technical effect is that the arc-shaped convex lens has a converging effect, so that the light is converged after passing through the arc-shaped convex lens, thereby solving the problem of random light diffusion direction, thereby forming the required light distribution pattern.

[0013] Furthermore, a diamond pattern is arranged on the light emitting surface, and a crown of the diamond pattern is arranged in a polygonal shape.

[0014] The specific technical effect is: three-dimensional brilliance is achieved by applying diamond patterns, so that the light emitted from the light-emitting surface can present a three-dimensional shining effect of diamonds.

[0015] Furthermore, the arc-shaped convex lens has a focus B, and the focus B coincides with the focus A.

[0016] The specific technical effect is: when focus B coincides with focus A, the optical efficiency is highest at this time.

[0017] Furthermore, the reflective surface is provided with a vertical stripe pattern.

[0018] The specific technical effect is that the vertical stripes provided on the reflective surface can diffuse the light, so that more light passing through the reflective surface is reflected onto the light emitting surface, thereby improving the utilization rate of the light.

[0019] Furthermore, a diffusion pattern is provided on the concentrator.

[0020] The specific technical effect is: the concentrator is provided with a diffusion pattern which can diffuse the light, so that more light entering the concentrator is reflected onto the reflecting surface, thereby improving the utilization rate of the light.

[0021] An integrated diamond three-dimensional effect thick-walled part, which includes any of the above-mentioned light-emitting structures, wherein a plurality of reflection units are arranged on the outer side of the rear end of the thick-walled structure, each of the reflection units includes a concentrator and a reflection surface, and the plurality of reflection units are connected as a whole.

[0022] The beneficial effects of the utility model are:

[0023] By adopting the design of a concentrator to concentrate the light on the reflective surface and then reflect it to the light-emitting surface through the reflective surface, the diffusion angle of the light is changed, thereby obtaining a more uniform lighting effect, avoiding the problem of random light diffusion direction in the prior art, meeting the lighting regulations, and improving the optical utilization efficiency. The light-emitting surface is designed to be a diamond pattern surface, so that the light emitted from the light-emitting surface can present a three-dimensional shining effect of a diamond.

Obviously, the described embodiments are 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 creative work are within the scope of protection of the utility model.

[0037] Embodiment 1:

[0038] like Figure 1 to Figure 2 As shown, a light emitting structure 1, comprising: a concentrator 2, a reflective surface 3, a thick-walled structure 4 and a light emitting surface 5;

[0039] The light emitting surface 5 is arranged at the front end of the thick-walled structure 4, the reflecting surface 3 is arranged at the rear end of the thick-walled structure 4, the concentrator 2 is arranged at the rear lower end of the thick-walled structure 4 and is arranged directly opposite the reflecting surface 3. The cross-section of the reflecting surface 3 is parabolic, and the reflecting surface 3 has a focus A. The light enters the concentrator 2 and is totally reflected by the reflecting surface 3 and converges at the focus A, and then reaches the light emitting surface 5 through the focus A. The light passes through the light emitting surface 5 and is emitted from the light emitting structure 1.

[0040] It should be noted that: the light passes through the concentrator 2 and is concentrated on the reflecting surface 3 and then reflected by the reflecting surface 3 to the light-emitting surface 5, which changes the diffusion angle of the light, thereby obtaining a more uniform lighting effect and avoiding the problem of random light diffusion direction in the prior art; according to different lighting effects, the position of the focus A can be adjusted and moved according to actual needs. When the position of the focus A moves, the parabolic shape of the cross-section of the reflecting surface 3 will also change accordingly. Therefore, the light type reflected by the reflecting surface 3 to the light-emitting surface 5 and then emitted by the light-emitting surface 5 will change accordingly, thereby achieving different lighting effects.

[0041] A light source 6 is arranged below the concentrator 2 , and the light output end of the light source 6 is arranged opposite to the light input end of the concentrator 2 . After the light emitted by the light source 6 enters the concentrator 2 , it is reflected by the concentrator 2 as collimated parallel light and hits the reflecting surface 3 .

[0042] It should be noted that the reflective surface of the condenser 2 is a smooth surface, and the light emitted by the light source 6 is reflected by the reflective surface of the condenser 2 to form collimated parallel light.

[0043] The concentrator 2 is arranged in a truncated cone structure, which includes a light inlet 7 and an arcuate side wall 8. The arcuate side wall 8 is arranged around the light inlet 7, and the light inlet 7 faces the reflecting surface 3. Light enters from the light inlet 7 and is reflected by the arcuate side wall 8 to the reflecting surface 3.

[0044] It should be noted that: the truncated cone structure has a first end and a second end, the diameter of the first end is smaller than the diameter of the second end, the second end is connected to the rear lower end of the thick-walled structure 4, and the light entrance 7 is opened on the first end. The light enters from the light entrance 7 and is reflected by the curved side wall 8 to form collimated parallel light, which hits the reflecting surface 3.

[0045] The thick-walled structure 4 further includes: an arcuate convex lens 9, which is arranged at the front end of the thick-walled structure 4, and the light-emitting surface 5 is formed on the arcuate convex lens 9, and the cross section of the arcuate convex lens 9 is arranged in a parabolic shape.

[0046] It should be noted that the arcuate convex lens 9 has a converging effect, so that the light is converged after passing through the arcuate convex lens 9, thereby solving the problem of random light diffusion direction, thereby forming a required light distribution pattern.

[0047] The light emitting surface 5 is provided with a diamond pattern, and the crown of the diamond pattern is arranged in a polygonal shape.

[0048] It should be noted that: by applying the diamond pattern, three-dimensional brilliance is achieved, so that the light emitted from the light-emitting surface 5 can present a three-dimensional shining effect of diamonds.

[0049] The arcuate convex lens 9 has a focus B, and the focus B coincides with the focus A.

[0050] It should be noted that when focus B coincides with focus A, the optical efficiency is the highest.

[0051] The reflective surface 3 is provided with a vertical stripe pattern.

[0052] It should be noted that the vertical stripes provided on the reflective surface 3 can diffuse the light, so that more light passing through the reflective surface 3 is reflected onto the light emitting surface 5, thereby improving the utilization rate of the light. The angle range of the vertical stripes is -40° to 40°.

[0053] See also Figure 2 As shown, the specific working principle of a light-emitting structure 1 is: the light emitted by the light source 6 is refracted onto the curved side wall 8 through the light entrance 7, and is reflected as collimated parallel light rays after passing through the curved side wall 8. These parallel light rays hit the reflecting surface 3, and are then reflected by the reflecting surface 3 and converge at the focal point A. Thereafter, the light rays continue to propagate in the direction of the curved convex lens 9, and the light rays pass through the light-emitting surface 5 and are emitted from the light-emitting structure 1. The light-emitting surface 5 is designed to be a diamond patterned surface, so that the light emitted from the light-emitting surface 5 can present a three-dimensional shining effect of a diamond.

[0054] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention.

[0055] The utility model also has the following implementation methods based on the above:

[0056] Embodiment 2:

[0057] The difference from the first embodiment is that a diffusion pattern is provided on the concentrator 2 .

[0058] It should be noted that various forms of diffusion patterns can be added to the concentrator 2 according to actual needs. The diffusion pattern is arranged on the inner wall of the concentrator 2. The diffusion pattern arranged on the concentrator 2 can increase the diffusion angle of the light reflected by the concentrator 2 and improve the uniformity of the lamp. The angle range of the diffusion pattern is -40° to 40°.

[0063] By adopting the design of the concentrator 2, the light is concentrated on the reflecting surface 3 and then reflected to the light emitting surface 5 through the reflecting surface 3, thereby changing the diffusion angle of the light, thereby obtaining a more uniform lighting effect, avoiding the problem of random light diffusion direction in the prior art, meeting the lighting distribution regulations, and improving the optical utilization efficiency.
