Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive interior technology, specifically relating to a light mixing structure that reduces ambient light color. Background Technology
[0002] With the development of the automotive industry, people are paying more and more attention to the aesthetics of car interiors. More and more car interiors are featuring various multi-color ambient lights. In the current technology, most ambient lights use a circular light guide structure to achieve RGB mixing.
[0003] However, traditional light guide structures require a length of more than 30mm to complete the mixing of RGB three colors, resulting in a long mixing distance and a bulky lamp body. At the same time, circular light mixing structures are prone to uneven light mixing, especially at bends where color light breaks are likely to occur. Utility Model Content
[0004] The purpose of this invention is to provide a light mixing structure that reduces the colored light of ambient lights, thereby solving the technical problems of excessively long light mixing distance in existing light mixing structures, which leads to bulky light guide volume and uneven light mixing resulting in colored light discontinuity. The invention achieves sufficient light mixing by performing multiple total internal reflections within the light mixing section, thereby reducing the length of the light mixing structure and avoiding bulky lighting fixtures.
[0005] To solve the above-mentioned technical problems, this utility model provides a light mixing structure for reducing ambient light color, comprising:
[0006] The light mixing section has a cross-sectional area that is shaped like a plum blossom. The light mixing section includes multiple reflective sections that surround each other to form a ring, and adjacent reflective sections are connected to each other.
[0007] Each of the inner walls of the reflective part is provided with a total reflective surface;
[0008] A light-emitting part, the end of which is connected to the end of the light-mixing part;
[0009] In this process, light rays are incident on a reflective part and undergo total reflection before being incident on an adjacent reflective part. After total reflection on multiple reflective parts, the light rays are incident on a light-emitting part.
[0010] Furthermore, five reflective parts are provided, and the angle between adjacent reflective parts is 70° to 75°.
[0011] The length of the reflective part is 20cm to 22cm.
[0012] Furthermore, a microprism is provided at the end of the light mixing section away from the light emitting section, and the microprism is used to directionally refract the scattered light.
[0013] Furthermore, an LED is disposed at the end of the light mixing section away from the light-emitting section, and the light from the LED is sequentially directed toward the microprism and the reflective section.
[0014] Furthermore, the light-emitting part includes: a prism-shaped lamp tube, and light guide teeth arranged along the axial direction of the lamp tube, the light guide teeth being disposed on the side wall of the lamp tube.
[0015] Furthermore, the light mixing part and the light emitting part are connected by a connecting part, and a first connecting surface is provided at one end of the connecting part near the light mixing part, and the first connecting surface matches the end face of the light mixing part.
[0016] Furthermore, a second connecting surface is provided at one end of the connecting portion near the light-emitting portion, and the second connecting surface matches the end face of the light-emitting portion.
[0017] The beneficial effects of this utility model are:
[0018] This invention, by setting up a light mixing section, allows the total reflection surfaces of the microprism and the reflector to work together. Light is first refracted directionally by the microprism onto the reflector, improving the light efficiency and uniformity. The light undergoes multiple total reflections on the five reflectors, achieving RGB light mixing during the total reflection process. Because the light undergoes multiple total reflections on the reflectors, the number of total reflections within the light mixing section is significantly increased, thereby reducing the length of the light mixing structure to achieve sufficient light mixing and reducing the bulkiness of the lamp.
[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] Example 1:
[0028] like Figures 1 to 3 As shown, a light mixing structure for reducing ambient light color includes: a light mixing part 1, a connecting part 2, and a light emitting part 3. The end of the light mixing part 1 is connected to the connecting part 2 and the light emitting part 3 in sequence. The light mixing part 1, the connecting part 2, and the light emitting part 3 are all coaxially arranged.
[0029] like Figure 1 As shown, the cross-sectional area of the light mixing section 1 is shaped like a plum blossom. The light mixing section 1 includes multiple reflective sections 11, which are arranged in a ring around each other. Adjacent reflective sections 11 are connected to each other in a plum blossom shape. The inner wall of each reflective section 11 is provided with a total reflection surface. There are five reflective sections 11, with an angle of 72° between adjacent reflective sections 11 and a length of 20cm. Light undergoes total reflection back and forth on multiple reflective sections 11, so the number of total reflections of light within the light mixing section 1 is significantly increased. This reduces the length of the light mixing structure to achieve sufficient light mixing, reducing the length of the light mixing structure from the common 30cm or more to 20cm, thus reducing the bulkiness of the lamp.
[0030] like Figure 2 As shown, a microprism is provided at the end of the light mixing section 1 away from the light-emitting section 3. The microprism is used to directionally refract the scattered light. An LED is provided at the end of the light mixing section 1 away from the light-emitting section 3. The light from the LED is directed towards the microprism and the reflector 11 in sequence. The light is first directionally refracted by the microprism onto the reflector 11 to improve the light efficiency and uniformity. The light undergoes multiple total internal reflections on the five reflectors 11, and RGB light mixing is achieved during the total internal reflection process on the reflectors 11. The light is directed towards the adjacent reflector 11 after total internal reflection on a reflector 11. After total internal reflection on multiple reflectors 11, the light enters the light-emitting section 3 and illuminates the light-emitting section, achieving the effect of ambient lighting.
[0031] Example 2:
[0032] Based on Embodiment 1, the light-emitting part 3 includes: a prism-shaped lamp tube 31, and light guide teeth 32 arranged along the axial direction of the lamp tube 31. The light guide teeth 32 are disposed on the side wall of the lamp tube 31. After the light is mixed by multiple total internal reflections in the light mixing part 1, it enters the lamp tube 31 and illuminates the lamp tube 31 to achieve the effect of ambient lighting. The light guide teeth 32 destroy the total internal reflection of the light in the lamp tube 31 and emit the mixed light out along a predetermined angle to achieve the lighting effect.
[0033] Example 3:
[0034] Based on Example 2, such as Figure 3 As shown, the light mixing section 1 and the light emitting section 3 are connected by a connecting section 2. The end of the connecting section 2 near the light mixing section 1 is provided with a first connecting surface 21, which matches the end face of the light mixing section 1, i.e., the first connecting surface 21 is in a plum blossom shape. The end of the connecting section 2 near the light emitting section 3 is provided with a second connecting surface 22, which matches the end face of the light emitting section 3, i.e., the second connecting surface 22 has the same cross-sectional area as the lamp tube 31. The light mixing section 1 and the light emitting section 3 are connected by the connecting section 2, so that the transition between the light mixing section 1 and the light emitting section 3 is smooth. The light passes through the light mixing section 1 and the connecting section 2 in sequence and enters the light emitting section 3 to light up the lamp tube 31.
[0035] In summary, the LED emitted light is first refracted by a microprism onto the reflector 11, improving the light efficiency and uniformity. The light undergoes total internal reflection on multiple reflectors 11 and achieves RGB light mixing. The increased number of total internal reflections improves the mixing efficiency, thereby reducing the length required for the mixing structure and reducing the bulkiness of the lamp. After undergoing multiple total internal reflections and completing the mixing in the mixing section 1, the light is sequentially injected into the connecting section 2 and the light-emitting section 3, and the mixed light illuminates the lamp tube 31 to achieve the effect of ambient lighting.
