Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a reflection system. Background Technology

[0002] With the rapid development of automotive lighting technology and consumers' increasing pursuit of lighting effects, production costs and efficiency are also urgent issues for automotive lighting suppliers to address. In existing solutions, light emitted from LEDs passes through a series of processing devices before exiting from the light-emitting surface to achieve a more uniform lighting effect.

[0003] In traditional projects, known solutions are inefficient due to the need for a large number of LEDs, increasing LED material costs while also complicating circuit design and raising heat risks. Existing reflection systems use a single reflection of the light source to form the emitted light, but this approach results in a short light emission length and a small light emission area, failing to meet the requirements for light brightness and uniformity. Utility Model Content

[0004] The technical problem to be solved by this utility model is: This utility model provides a reflection system in which incident light is reflected multiple times to form outgoing light, thereby increasing the outgoing light length, expanding the outgoing light area, and ensuring the brightness and uniformity of the light.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a reflection system, including a first reflector and a second reflector disposed inside the first reflector;

[0006] The first reflector includes a collimating surface A1, light-emitting surfaces A2 and A3 located on both sides of the collimating surface A1, and a reflecting surface A4 located at the end of the collimating surface A1. The collimating surface A1 collimates the light from the light source into incident light that is approximately parallel.

[0007] The second reflector includes a reflective surface B1, a reflective surface B2, and a light-emitting surface B3;

[0008] The reflecting surfaces B1, B2, and A4 reflect the incident light. The light emitting surface A2 emits the light reflected by the reflecting surface B1, the light emitting surface A3 emits the light reflected by the reflecting surface B2, and the light emitting surface B3 emits the light reflected by the reflecting surface A4.

[0009] Furthermore, in order to increase the light emission length and light emission area, the reflective surface B1 and the light emission surface A2 are arranged in parallel relative to each other, as are the reflective surface B2 and the light emission surface A3. The light emission surface B3 is located directly above the reflective surface A4 and is arranged parallel to the reflective surface A4.

[0010] Furthermore, in order to control the angle of the reflected light, the angle between the reflecting surface B1 and the reflecting surface B2 is 80-100°, and the reflecting surface B1 and the reflecting surface B2 are at 40-50° with the direction of the incident light.

[0011] Furthermore, in order to control the angle of the emitted light, the reflecting surface A4 and the light-emitting surface B3 are at an angle of 40-50° to the direction of the emitted light.

[0012] Furthermore, in order to make the emitted light emit horizontally, the light-emitting surface A2, light-emitting surface A3, reflecting surface B1 and reflecting surface B2 are arranged perpendicular to the horizontal direction.

[0013] Furthermore, in order to ensure uniform reflected light, the surfaces of the light-emitting surface A2, light-emitting surface A3, reflective surface B1, and reflective surface B2 have diffusion patterns.

[0014] Furthermore, in order to ensure uniform light after collimation, the collimation surface A1 is a parabolic surface with a diffusion pattern on its surface.

[0015] Furthermore, in order to assemble the second reflector into a whole structure, there is a connecting surface between the two sides and the bottom of the light-emitting surface B3 and between the reflective surface B1 and the reflective surface B2.

[0016] Furthermore, in order to improve the brightness of the reflected light, the inner surface of the first reflector is plated with aluminum, and the outer surface of the second reflector is plated with aluminum.

[0017] Furthermore, in order to combine multiple first reflectors and multiple second reflectors, adjacent first reflectors are connected by light-emitting surfaces A2 and A3.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] In this new reflective system, incident light passes through reflective surface B1 and light-emitting surface A2, reflective surface B2 and light-emitting surface A3, and reflective surface A4 and light-emitting surface B3 to form three light-emitting paths. The light rays reflected multiple times by the first and second reflective elements can be more evenly distributed. Light-emitting surfaces A2 and A3 can double the original light-emitting length, and together with light-emitting surface B3, the light-emitting area can triple the original area, increasing the light-emitting range of a single light source. Moreover, the light emission is more uniform after multiple reflections.

[0020] This utility model's reflection system allows for adjustments to the angles of reflective surfaces B1, B2, A4, and B3, or to the proportion of the reflective surface area of ​​each unit, as needed. By adjusting the number of the first and second reflective elements, it can adapt to the actual application and installation connection method, thereby reducing costs. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] like Figures 1 to 3 As shown, a reflection system includes a first reflector 1 and a second reflector 2. The second reflector 2 is disposed inside the first reflector 1 to form a reflection assembly, and multiple first reflectors 1 are connected in sequence to form a complete reflection system.

[0034] like Figure 4 As shown, the first reflector 1 includes a collimating surface A1, light-emitting surfaces A2 and A3 located on both sides of the collimating surface A1, and a reflecting surface A4 located at the end of the collimating surface A1. The light-emitting surfaces A2 and A3 are located on the left and right sides of the upper end of the collimating surface A1, and the reflecting surface A4 is connected to the end of the collimating surface A1 through a connecting surface.

[0035] Collimating surface A1 collimates the light rays from the light source into approximately parallel incident light. Collimating surface A1 is a parabolic surface, and its surface has a diffusion pattern.

[0036] The first reflectors 1 are connected by light-emitting surfaces A2 and A3. In this way, multiple first reflectors 1 can be formed into a single component.

[0037] like Figure 5 and Figure 6 As shown, the second reflector 2 includes a reflecting surface B1, a reflecting surface B2, and a light-emitting surface B3. Connecting surfaces are formed between the sides and bottom of the light-emitting surface B3 and between it and the reflecting surfaces B1 and B2. The second reflector 2 forms an integral structure through the reflecting surface B1, the reflecting surface B2, the light-emitting surface B3, and the connecting surfaces.

[0038] Reflecting surface B1, emitting surface A2, reflecting surface B2, and emitting surface B3 are located on the same plane. Reflecting surface B1 and emitting surface A2 are arranged parallel to each other, and reflecting surface B2 and emitting surface B3 are arranged parallel to each other, with equidistant projection distances in all directions. The angle between reflecting surface B1 and reflecting surface B2 is 80-100°, and the angle between reflecting surface B1 and reflecting surface B2 and the direction of incident light is 40-50°. Preferably, the angle between reflecting surface B1 and reflecting surface B2 can be 90°, that is, the angle between reflecting surface B1 and reflecting surface B2 and the direction of incident light is 45°.

[0039] The light-emitting surface B3 is located directly above and parallel to the reflecting surface A4, with equidistant projections in all directions. The reflecting surface A4 and the light-emitting surface B3 form an angle of 40-50° with the direction of the emitted light.

[0040] Reflecting surfaces A4, B1, and B2 reflect incident light. Light emitting surface A2 emits light reflected by reflecting surface B1, light emitting surface A3 emits light reflected by reflecting surface B2, and light emitting surface B3 emits light reflected by reflecting surface A4.

[0041] The light-emitting surfaces A2 and A3, and the reflecting surfaces B1 and B2 are arranged perpendicular to the horizontal direction. The surfaces of the light-emitting surfaces A2 and A3, and the reflecting surfaces B1 and B2 have diffusion patterns. The structure can be designed and configured with diffusion patterns or textured surfaces to diffuse light, according to requirements.

[0042] The inner surfaces of the first reflector 1 are coated with aluminum, namely the collimating surface A1, the light-emitting surface A2, the light-emitting surface A3, and the reflecting surface A4, which can achieve better light reflection. The outer surfaces of the second reflector 2 are coated with aluminum, namely the reflecting surface B1, the reflecting surface B2, and the light-emitting surface B3, thereby improving the brightness of the reflected light.

[0043] The working principle of this utility model is as follows: Figure 7 As shown, the LED light source is located above the first reflector 1. The light source illuminates the collimating surface A1, which collimates the light into approximately parallel incident light. At this point, the incident light is divided into three parts. The first part of the light strikes the reflecting surface B1, is reflected by B1 into the air, and then strikes the emitting surface A2, where it is reflected to form the first path of emitted light. The second part of the light strikes the reflecting surface B2, is reflected by B2 into the air, and then strikes the emitting surface A3, where it is reflected to form the second path of emitted light. The third part strikes the reflecting surface A4, is reflected by A4 into the air, and then strikes the emitting surface B3, where it is reflected to form the third path of emitted light.

[0044] The light-emitting length of the reflective system is the distance from the outer edges of light-emitting surfaces A2 and A3, while the light-emitting surface length of a traditional reflector is the length of a single light-emitting surface. This structure doubles the light-emitting length. Simultaneously, light-emitting surfaces A2, A3, and B3 together triple the light-emitting area, resulting in more uniform light emission after multiple efficient reflections. The angle relationship between the light-emitting and reflecting surfaces, or the proportion of the reflective surface area of ​​each unit, can be adjusted according to actual usage requirements, along with the installation and connection method between the reflective system and the actual application.

[0045] In summary, the present invention's reflection system emits light after multiple reflections within the system, allowing for a larger luminous range controlled by a single LED. This saves on LEDs while expanding the light-emitting area, reducing costs, and providing uniform and efficient light emission for more even illumination.

[0046] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
