Description

Technical Field

[0002] With the development of technology and the improvement of human aesthetics, the design of car lights is no longer limited to meeting basic regulatory requirements. In addition, more uniform and distinctive lighting effects are required, such as starry sky effect, diamond effect, water ripple effect, etc.

[0003] The common water ripple luminous effect is mainly achieved by projecting LED light directly onto the water ripple body, so that the water ripple effect can be displayed on the side or opposite illuminated surface. However, this solution often has low light efficiency and requires higher-power LEDs, resulting in increased product costs. In addition, traditional optical solutions can only achieve a water ripple effect that gradually changes along a straight line. Utility Model Content

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] like Figures 1 to 4As shown, the utility model provides a thick-walled light guide structure, including a collimating lens 1, a side water wave pattern 2 and a top reflective surface 3. The top reflective surface 3 is arranged directly behind the collimating lens 1. It can be understood that the above-mentioned directly behind position refers to the directly behind along the direction of light propagation. The side water wave pattern 2 is connected and arranged between the collimating lens 1 and the top reflective surface 3, and is arranged around the top reflective surface 3. The light emitted by the LED light source is focused by the collimating lens 1 and irradiated onto the top reflective surface 3, and the light is reflected and deflected by the top reflective surface 3, and refracted out of the thick-walled structure through the side water wave pattern 2, and irradiated onto the illuminated surface 4 to form a water ripple effect radiating from the center to the surroundings. The utility model realizes the water ripple effect radiating from the center to the surroundings through a single group of LEDs and a single optical structure; the structure is simple, the light-emitting area is larger, and the cost is lower. For details, please refer to Figure 4 As shown, Figure 4 An imaging effect diagram of the wall-thick light-guiding structure provided in this application is provided, in which water ripples zigzag and diverge from the center to the surrounding areas, achieving a three-dimensional sense of space.

[0029] More specifically, the collimating lens 1 includes a top collimating surface 11, a side refractive surface 12, and a side collimating surface 13, which are sequentially connected. The top collimating surface 11 is disposed in the middle of the side refractive surface 12, and the side collimating surface 13 is disposed outside the side refractive surface 12. Part of the light emitted by the LED can directly pass through the top collimating surface 11 and illuminate the top reflective surface 3. Another part can pass through the side refractive surface 12 and illuminate the side collimating surface 13, and then be reflected by the side collimating surface 13 and onto the top reflective surface 3. This structural design facilitates the collimation of light into the thick-walled structure, allowing the thick-walled structure to better uniform light.

[0030] In order to improve the luminous effect, the surface of the top reflective surface 3 is aluminum-plated to facilitate light reflection, thereby improving the reflection efficiency and preventing bright spots in the center of the luminous effect.

[0031] More specifically, the top reflective surface 3 includes a central arc portion 31 and side reflective portions 32. The central arc portion 31 is aligned with the collimating lens 1, while the side reflective portions 32 are disposed around the central arc portion 31. This provides a sufficiently large reflective surface for reflecting light, achieving uniform light reflection and providing a large reflective area. The central arc portion 31 eliminates sharp corners on the mold, making it easier to process. The side reflective portions 32 are inclined relative to the central arc portion 31, resulting in a V-shaped cross-section of the top reflective surface 3. The side reflective portions 32 are free-form surfaces with a simple structure, facilitating light reflection and increasing the light diffusion angle.

[0032] The surface of the side water wave pattern 2 is an uneven water wave surface structure, so that the thick wall structure forms different pattern sizes, which improves the realism of the water wave and reduces the manufacturing difficulty of the side water wave pattern 2.

[0033] The material of the thick-walled light guide structure is any one of glass, PC material or PMMA material, which reduces the cost of the thick-walled light guide structure.

[0034] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
