Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically a crystal-effect optical system. Background Technology

[0002] As a hallmark of the BMW 7 Series, crystal headlights achieve a high-end and sophisticated static effect, leading to an increasing number of models and turn signals considering adopting this technology. However, currently, this feature has relatively low and unfocused light efficiency, and the light emission direction follows the normal direction of the design, resulting in some functions requiring a large energy input; at the same time, the refraction of light causes lower brightness in areas with more slanted facets. Summary of the Invention

[0003] The purpose of this invention is to provide a crystal-effect optical system to solve the problems of low light efficiency, lack of focus, and uneven brightness in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a crystal-effect optical system, comprising an LED body, a thick-walled component at the front end of the LED body, a collimating lens portion inside the thick-walled component for collecting light energy, a corn kernel-patterned surface on the surface of the thick-walled component, the corn kernel-patterned surface for adjusting the angle of light, and the energy concentration effect of the corn kernel-patterned surface is better than that of the diamond pattern, and the diffusion angle is more controllable, a light-diffusing material at the front end of the thick-walled component, the light-diffusing material for achieving uniform light diffusion and for making the internal thick-walled pattern invisible under static conditions, and a crystal at the front end of the light-diffusing material, the crystal for achieving a crystal-clear and dazzling effect.

[0005] Preferably, the light-diffusing material has a transparent electroplated outer surface, which is used to shield internal defects under static conditions and improve uniformity and brilliance.

[0006] Preferably, the light-diffusing material has multiple through slots at its top and bottom, and the thick-walled component has a triangular block at the corresponding position of each slot, and the light-diffusing material is connected to the slots and blocks by engaging.

[0007] Preferably, a fixing plate is provided at the bottom of the LED body, and a fixing hole is provided on the fixing plate.

[0008] Preferably, the horizontal cross-section of the light-diffusing material is S-shaped, and the horizontal cross-section of the crystal is C-shaped.

[0009] Preferably, the light-diffusing material has a groove formed on one side of the thick-walled component, the thick-walled component is adapted to the groove cavity, and the vertical cross-section of the light-diffusing material is U-shaped.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This application achieves uniform lighting and static effects by using a light-diffusing material with transparent electroplating. It ensures both a crystal-clear and dazzling effect in static conditions and a relatively uniform effect when lit, while simultaneously achieving the optical effect of crystal lighting. Under the premise of ensuring the effect, it achieves energy concentration and light concentration along the prescribed direction.

[0011] 2. This application enhances the brilliance of crystal and the uniformity of its illumination state by combining light-diffusing materials and transparent electroplating, making its internal structure and defects hidden or invisible, thereby improving the overall aesthetics of the optical system for crystal effects.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution for a crystal-effect optical system, including an LED body 1, a thick-walled component 2 at the front end of the LED body 1, a collimating lens inside the thick-walled component 2 for collecting light energy, a corn kernel-patterned surface 3 on the surface of the thick-walled component 2 for adjusting the angle of light, and the energy concentration effect of the corn kernel-patterned surface 3 is better than that of a diamond pattern, and the diffusion angle is more controllable, a light-diffusing material 4 at the front end of the thick-walled component 2 for achieving uniform light diffusion and for making the internal thick-walled pattern invisible when static, and a crystal 6 at the front end of the light-diffusing material 4 for achieving a crystal-clear and dazzling effect. Specifically: the function of the thick-walled component 2 is to verify the X direction of light (to ensure compliance with regulations and uniformity); the function of the light-diffusing material 4 is to make the illumination more uniform and eliminate the corn kernel pattern 3 on the thick-walled component 2; the function of the transparent electroplating 5 is to present a metallic feel when not illuminated, and to make it statically sparkle; the function of the crystal 6 is to make it statically sparkle in sunlight, and when illuminated, the illuminated area is different from different viewing angles, giving people a dynamic effect.

[0016] like Figure 1 - Figure 2 As shown, the light-diffusing material 4 has a transparent electroplating 5 on its outer surface, which is used to shield internal defects under static conditions and improve uniformity and brilliance.

[0017] like Figure 1 and Figure 2 As shown, the light-diffusing material 4 has multiple through slots 7 at its top and bottom. The thick-walled component 2 has a triangular block 8 at the corresponding position of each slot 7. The light-diffusing material 4 is connected to the slot 7 by engaging with the block 8.

[0018] like Figure 4 As shown, a fixing plate 9 is provided at the bottom of the LED body 1, and a fixing hole 10 is provided on the fixing plate 9.

[0019] like Figure 1 and Figure 2 As shown, the horizontal cross-section of the light-diffusing material 4 is S-shaped, and the horizontal cross-section of the crystal 6 is C-shaped.

[0020] like Figure 1 and Figure 2 As shown, the light-diffusing material 4 has a groove 11 formed on one side of the thick-walled part 2. The thick-walled part 2 is adapted to the cavity of the groove 11. The vertical cross section of the light-diffusing material 4 is U-shaped.

[0021] The working principle of this utility model is as follows: light is emitted from the LED body 1, passes through the collimating lens, is reflected by the upper 45-degree reflective surface, is then slightly diffused by the corn kernel pattern surface 3 on the front surface of the thick-walled part 2, then undergoes secondary diffusion through the light diffusion material 4, and finally is emitted through the crystal 6. Due to defects such as the internal patterns and installation structure that are visible in static conditions, a light-diffusing material 4 is added between the crystal 6 and the thick-walled component 2 to make the internal thick-walled patterns invisible in static conditions. However, simply adding the light-diffusing material 4 would worsen the brilliance of the crystal 6. Therefore, a layer of transparent electroplating 5 is added to the outer surface of the light-diffusing material 4, which greatly improves the brilliance of the crystal 6 and makes the lighting state more uniform.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
