Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and in particular to a three-dimensional light-emitting optical structure. Background Technology

[0002] With the rapid development of automotive lighting technology, users have increasingly higher requirements for the style and function of lighting fixtures. Simply having a single lighting effect is not competitive.

[0003] Currently, the thin walls of traditional inner lamp shades typically employ condenser patterns. This approach is mainly used in light guide plate structures and is suitable for light-emitting surfaces with relatively regular shapes. Although the structure is simple and can achieve good light-emitting effects, it can only be used for single-layer light guide plates and can only achieve a single light-emitting effect. It cannot achieve multi-layer or three-dimensional light-emitting effects, and therefore does not conform to future trends.

[0004] Furthermore, existing technologies also employ a multi-layered inner lampshade stacking scheme. This scheme uses multiple inner lampshades stacked in space to achieve complex lighting and three-dimensional effects. However, it requires more parts and light sources, resulting in higher costs and more complex and cumbersome assembly. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a three-dimensional light-emitting optical structure that can achieve complex, superimposed light-emitting and three-dimensional effects with a single component, thereby reducing cost and assembly difficulty.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0007] A three-dimensional light-emitting optical structure includes a thick-walled body, one end of which has a collimation structure, and the other end of which is away from the collimation structure has a first total reflection surface and a second total reflection surface. The first and second total reflection surfaces are both located in the collimation direction of the collimation structure and are staggered with each other. The first total reflection surface is located behind the second total reflection surface.

[0008] The bottom of the thick-walled component body is also formed with a rear luminous surface and a front luminous surface. The rear luminous surface is located at the reflection position of the first total reflection surface, and the front luminous surface is located at the reflection position of the second total reflection surface.

[0009] The rear light-emitting surface has a rear light-emitting surface diffusion structure on its front side, and the front light-emitting surface has a front light-emitting surface diffusion structure with a smaller range than the rear light-emitting surface diffusion structure on its front side.

[0010] The light emitted by the light source can be collimated into the body of the thick-walled component through the collimation structure, and then incident on the first total reflection surface and the second total reflection surface; the light reflected by the first total reflection surface will enter the rear light-emitting surface and exit from the position of the diffusion structure of the rear light-emitting surface, while some of the emitted light can enter the front light-emitting surface to form a superposition effect; the light reflected by the second total reflection surface will enter the front light-emitting surface and exit from the position of the diffusion structure of the front light-emitting surface.

[0011] Furthermore, the angle between the first total reflection surface and the second total reflection surface and the collimation direction of the collimation structure is 45°.

[0012] Furthermore, the rear emitting surface and the front emitting surface are at the same height and parallel to each other.

[0013] Furthermore, the angle between the rear emitting surface and the front emitting surface and the collimation direction of the collimation structure is 90°.

[0014] Furthermore, the first total reflection surface and the second total reflection surface are vertical striped surfaces, flat surfaces, or corn kernel patterned surfaces.

[0015] Furthermore, the collimation structure is a concentrator.

[0016] Furthermore, the surface of the concentrator has a pattern.

[0017] Furthermore, the concentrator is a circular concentrator, a nested concentrator, or a stretched concentrator.

[0018] Furthermore, the material of the thick-walled component body is transparent PC or PMMA.

[0019] Furthermore, the rear light-emitting surface diffusion structure and the front light-emitting surface diffusion structure are patterned or textured.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects:

[0021] This invention utilizes a single thick-walled component with a collimation structure, staggered first and second total internal reflection surfaces, a rear emitting surface, a front emitting surface, and a rear and front emitting surface diffusion structure. By arranging the relative positions of these structures according to the direction of light, the light emitted from the light source, upon entering the thick-walled component, can be staggered onto the first and second total internal reflection surfaces, then reflected into the rear and front emitting surfaces, and finally emitted through the rear and front emitting surface diffusion structures. Some light emitted from the rear emitting surface diffusion structure can even re-enter the front emitting surface and then be emitted again. This achieves a superimposed luminescence and a three-dimensional effect. The forms of the rear and front emitting surface diffusion structures can be adjusted according to design requirements, thus meeting diverse customer needs. Crucially, this invention is made using only a single thick-walled component. Through its shape construction and optical structure, complex, superimposed luminescence and three-dimensional effects can be achieved, simplifying the structure, reducing costs, and lowering assembly difficulty and efficiency.

Detailed Implementation

[0027] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] like Figure 1-4 As shown, in this embodiment, a three-dimensional light-emitting optical structure is provided, the main body of which is composed of a single thick-walled component, and the material of the thick-walled component is transparent PC or PMMA.

[0029] A collimation structure 1 is provided at one end of the thick-walled component body. Specifically, the collimation structure 1 is a concentrator. The surface of the concentrator is patterned to make the light incident effect more uniform. Of course, the concentrator can be a circular concentrator, a nested concentrator, or a stretched concentrator.

[0030] At the other end of the thick-walled component body away from the collimation structure 1, a first total reflection surface 2 and a second total reflection surface 3 are formed. The first total reflection surface 2 and the second total reflection surface 3 are vertical striped surfaces, flat surfaces, or corn kernel patterned surfaces, and refer to Figure 1 As shown, the first total reflection surface 2 and the second total reflection surface 3 are both located in the collimation direction of the collimation structure 1 and are staggered with each other, with the first total reflection surface 2 located behind the second total reflection surface 3. Simultaneously, a rear emitting surface 4 and a front emitting surface 5 are also formed at the bottom of the thick-walled component body. (Refer to...) Figure 3 and Figure 4 As shown, the rear emitting surface 4 is located at the reflection position of the first total reflection surface 2, and the front emitting surface 5 is located at the reflection position of the second total reflection surface 3.

[0031] In addition, a rear light-emitting surface diffusion structure 41 is located in front of the rear light-emitting surface 4, and a front light-emitting surface diffusion structure 51 is located in front of the front light-emitting surface 5. These structures are used to disrupt total internal reflection of light, and the area of ​​the front light-emitting surface diffusion structure 51 is smaller than that of the rear light-emitting surface diffusion structure 41. Specifically, the rear light-emitting surface diffusion structure 41 and the front light-emitting surface diffusion structure 51 can be patterned, textured, or other structures capable of disrupting total internal reflection of light. Of course, the forms of the rear light-emitting surface diffusion structure 41 and the front light-emitting surface diffusion structure 51 can be set and adjusted according to the design requirements to present various three-dimensional superimposed effects, thereby meeting the diverse needs of customers.

[0032] Specifically, refer to Figure 1 , 3 The structure of 4 is optimized in this embodiment to facilitate processing and production. The angle between the first total reflection surface 2 and the second total reflection surface 3 and the collimation direction of the collimation structure 1 is 45°. The rear light-emitting surface 4 and the front light-emitting surface 5 are at the same height and parallel to each other. The angle between the rear light-emitting surface 4 and the front light-emitting surface 5 and the collimation direction of the collimation structure 1 is 90°.

[0033] For reference, please refer to this setting. Figure 3 , Figure 4The illustrated light path diagram shows that when the light source emits light, the emitted light is collimated into the thick-walled component body through the collimating structure 1, then strikes the first total reflection surface 2 and the second total reflection surface 3, and is reflected into the rear emitting surface 4 and the front emitting surface 5. The light reflected by the first total reflection surface 2 enters the rear emitting surface 4 and exits from the position of the rear emitting surface diffusion structure 41. Simultaneously, some of the emitted light also enters the front emitting surface 5 for further emission, creating a superimposed effect. Conversely, the light reflected by the second total reflection surface 3 enters the front emitting surface 5, with some of it superimposed on the aforementioned light, and the rest exiting from the position of the front emitting surface diffusion structure 51. Finally, a superimposed luminous effect and a three-dimensional effect are achieved. Of course, the forms of the rear emitting surface diffusion structure 41 and the front emitting surface diffusion structure 51 can be adjusted according to design requirements to meet diverse customer needs. Meanwhile, the most crucial aspect of this embodiment is that it is made using only one part, the thick-walled body. Through its shape construction and optical structure forming settings, complex and superimposed light-emitting and three-dimensional effects can be achieved. This not only simplifies the structure and reduces costs, but also reduces assembly difficulty and improves assembly efficiency.
