Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive lighting technology, specifically relating to a novel reflector structure. Background Technology
[0002] Different functions of vehicle lights are matched with different light colors, such as white light for daytime running, yellow light for turn signals, and red light for braking. Different colors of light usually require different light sources. However, vehicle light structures are becoming more and more compact and integrated. Therefore, it is now common to use a collimation structure at the light-incident end, such as a condenser or reflector, to share multiple light sources. However, since a collimation structure at the light-incident end has only one focal point, multiple light sources cannot all be at the focal point. This leads to a reduction in the efficiency of the overall optical system, which affects the lighting effect of the vehicle lights. In order to ensure the lighting effect of vehicle lights and improve the compactness of the vehicle light structure, a new type of reflector structure is proposed. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] The novel reflector structure of this utility model is described in detail below with reference to the accompanying drawings.
[0028] like Figures 1-3 As shown, the novel reflector structure according to an embodiment of the present invention includes: a main body 1, a first light source 2, and a second light source; the main body 1 is made of transparent material, and a plurality of reflective surfaces 11 are formed on the main body 1, the plurality of reflective surfaces 11 are spaced apart, and the space between the plurality of reflective surfaces 11 forms a light-transmitting surface 12; the first light source 2 faces the reflective surface 11, and the reflective surface 11 reflects the light from the first light source 2 to the light outlet; the light emitted by the second light source is directed toward the light outlet, the main body 1 is located on the light outlet path of the second light source, and the second light source is directed toward the light outlet through the light-transmitting surface 12.
[0029] In this embodiment, the first light source 2 and the second light source are light sources of different colors. During the lighting process of the first light source 2, the light from the first light source 2 is totally reflected to the light outlet after passing through the reflective surface 11, thereby achieving the lighting effect of the first light source 2. When the second light source is lit, its light passes through the light-transmitting surface 12 and is emitted to the light outlet, thereby achieving the lighting effect of the second light source. By forming the reflective surface 11 and the light-transmitting surface 12 on the main body 1, the first light source 2 and the second light source are combined together, making the structure more compact. It also avoids placing the first light source 2 and the second light source in the same position. At the same time, the use of multiple reflective surfaces 11 and multiple light-transmitting surfaces 12 alternately achieves the uniformity of lighting.
[0030] Furthermore, the first light source 2 can be a light-emitting component such as an LED, or a combination of a light-emitting component and a reflective component. The second light source can also be a light-emitting component, or a combination of a light-emitting component and a reflective component; the specific configuration depends on the installation space. In other words, when the second light source is a light-emitting component, the second light source can be located... Figure 1 The solid line shown indicates the area directly behind the light path; when the second light source is a combination of a light-emitting component and a reflective component, the light-emitting component can be located either above or below the rear of the main body 1, or the light can be guided by the reflective component to... Figure 1 The solid line shown represents the path of the light ray.
[0031] The reflecting surface 11 is a curved surface with a focal point, and the first light source 2 is located at the focal point of the reflecting surface 11 to achieve a collimation effect.
[0032] The main body 1 has an arc-shaped structure, and the first light source 2 is located inside the arc-shaped structure to increase the coverage area of the light emitted by the first light source 2 and reflect the light emitted by the first light source 2.
[0033] In this embodiment, the main body 1 includes most of the area where the light from the first light source 2 diverges, thereby improving the utilization rate of light. That is, multiple reflecting surfaces 11 complete the reflection while achieving the collimation function, avoiding the need to add collimation unit components to the first light source 2, thus saving the number of components.
[0034] A collimation unit is provided between the second light source and the main body 1 to collimate the light emitted by the second light source.
[0035] The thickness of the main body 1 is uniform.
[0036] In this embodiment, the light emitted by the second light source is collimated by the collimation unit so that the light before entering the main body 1 is horizontal and remains horizontal after passing through the main body 1 with uniform thickness. This achieves that the emission angle of the light from the second light source after passing through the light-transmitting surface 12 is consistent with the light outlet.
[0037] The inner or outer surface of the reflective surface 11 is coated with an aluminum layer. That is, aluminum is coated on the main body 1, which simplifies the production process, reduces production costs, and saves installation steps.
[0038] The main body 1 is made of PMMA, PC or other transparent materials.
[0039] Multiple reflective surfaces 11 are spaced apart along the length and / or width of the main body 1.
[0040] Specifically, the reflective surface 11 is elongated, and multiple reflective surfaces 11 are arranged at intervals along its width to form vertical or horizontal stripes on the main body 1; or the reflective surface 11 is rectangular, arranged in multiple rows along the length of the main body 1, and adjacent rows of reflective surfaces 11 are staggered to achieve a dotted arrangement, and the specific interval distance can be set according to the design requirements.
[0041] Multiple reflective surfaces 11 are arranged outwardly at intervals along the optical axis of the first light source 2.
[0042] Specifically, the reflective surface 11 is annular, diffuses outward from the optical axis of the first light source 2 and is spaced apart to meet the needs of different light emission patterns.
[0043] Both the reflective surface 11 and the light-transmitting surface 12 are provided with diffusion patterns to increase the uniformity of illumination.
[0044] A third light source may be added at the location of the first light source 2 or the second light source.
[0045] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
