Description

Technical Field

[0001] This invention relates to vehicle lights, and more particularly to a vehicle light with a reflective structure. Prior Technology

[0002] Conventional automotive lights, such as but not limited to headlights, brake lights, and daytime running lights, include a lamp cover, a light source disposed within the lamp cover, and a reflective structure surrounding the light source. The reflective structure is used to alter the light transmission path of the light source to achieve a desired luminous effect. However, conventional automotive lights produce different luminous effects by changing the number, distribution, brightness, or configuration of the light source or the reflective structure. The design of the reflective structure and the resulting luminous effect are limited and lack variability. Furthermore, they suffer from high costs, poor precision, and difficulty in assembly during production and processing, presenting shortcomings that urgently need improvement.

[0003] Therefore, it is necessary to provide a novel and progressive vehicle headlight to solve the above problems. Summary of the Invention

[0004] The main objective of this invention is to provide a vehicle lamp that can produce a special luminous effect, and whose reflective structure has a wide margin of production error.

[0005] To achieve the above objectives, the present invention provides a vehicle lamp, comprising: a light source and a reflector. The light source emits a light beam; the reflector includes at least one reflective unit for receiving and reflecting the light beam, the at least one reflective unit including a plurality of light-guiding blocks arranged in a matrix, each light-guiding block having a reflective surface; wherein, a first height difference and a second height difference are respectively between the reflective surface of one of the plurality of light-guiding blocks and the reflective surfaces of at least two adjacent light-guiding blocks, the first height difference and the second height difference being different.

Implementation

[0007] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The use of "a" or "at least one" before the terms mentioned herein is not a limitation on the quantity, and may also be "multiple" depending on the requirements. Such variations in quantity are also within the scope of protection, and are therefore stated in advance.

[0008] Please refer to Figures 1 to 7, which show a preferred embodiment of the present invention. The vehicle lamp 1 of the present invention includes a light source 10 and a reflector 20.

[0009] The light source 10 emits a light beam; the reflector 20 includes at least one reflective unit 21 for receiving and reflecting the light beam, the at least one reflective unit 21 including a plurality of light-guiding blocks 211 arranged in a matrix, each light-guiding block 211 having a reflective surface 212; wherein, the reflective surface 212 of one of the plurality of light-guiding blocks 211 has a first height difference and a second height difference with the reflective surfaces 212 of at least two adjacent light-guiding blocks 211, the first height difference and the second height difference being different. Thus, the reflective surfaces 212 of the plurality of light-guiding blocks 211 extend discontinuously, reflecting the light beam in multiple directions and producing irregular light spots and soft halo effects.

[0010] Preferably, each light guide block 211 has a rectangular outer contour. Viewed from one frontal direction of the reflector 20, the plurality of light guide blocks 211 are adjacent and form a plurality of perpendicularly intersecting longitudinal lines 213 and a plurality of transverse lines 214, as shown in FIG6. The plurality of light guide blocks 211 can be molded, for example, which is easy to manufacture and design. Each reflective surface 212 can be a plane, a convex surface, a concave surface, or include multiple irregular cross-sections, which can be designed according to requirements to produce different light emission effects.

[0011] In this embodiment, the plurality of light-guiding blocks 211 have the same cross-sectional profile dimensions; the plurality of light-guiding blocks 211 includes a first light-guiding block 211a, a second light-guiding block 211b, and a third light-guiding block 211c arranged consecutively in the same row or column. A first height difference exists between the reflective surface of the first light-guiding block 211a and the reflective surface 212 of the second light-guiding block 211b, and a second height difference exists between the reflective surface of the second light-guiding block 211b and the reflective surface 212 of the third light-guiding block 211c. Preferably, the height differences between the reflective surface 212 of at least one light-guiding block 211 and the reflective surfaces 212 of the four adjacent light-guiding blocks 211 are all different, allowing the light to interfere with each other or produce multiple reflections, resulting in a better reflection effect. Each light-guiding block 211 also has a plurality of side surfaces 218. Each side surface 218 extends along one of the thickness directions of the reflector 20 and is connected between two adjacent reflective surfaces 212. The first height difference and the second height difference correspond to the height of one of the side surfaces 218 extending along the thickness direction, which can produce irregular light spots and effectively increase the interference and diffusion effects of light.

[0012] Furthermore, the reflector 20 includes a plurality of interconnected reflective units 21, each reflective unit 21 having an arc-shaped concave substrate 215, with a ridge 216 formed between two adjacent substrates 215; the plurality of light-guiding blocks 211 are integrally protruding from a concave side 217 of the substrate 215, providing excellent light reception and focusing effects. The light source 10 includes a plurality of light-emitting elements 11 and a circuit board 12, each light-emitting element 11 facing a reflective unit 21 and offset from each ridge 216, so that the light from each light-emitting element 11 can be reliably projected into the concave sides 217. Each substrate 215 extends arcuately along a longitudinal direction L and a transverse direction H transverse to the longitudinal direction L, thereby making the reflective surfaces 212 generally arranged in an arc-shaped concave pattern, producing a light diffusion effect.

[0013] It should be noted that the vehicle lamp 1 of the present invention uses the different height differences between the reflective surfaces 212 and the curvature matching of each substrate 215 to generate different degrees of interference and reflection of light, thereby providing a special light-emitting effect. Even if there are some slight deviations in the precision of the height difference between the reflective surfaces 212, a similar effect can still be achieved, with a wider production error margin, which is convenient for manufacturing.

[0014] The headlight 1 further includes a housing 30, which includes a base 31 and a light cover 32 covering the base 31. The reflector 20 further includes a fixing part connected to one side of the at least one reflecting unit 21. The light source 10 and the fixing part are respectively positioned on opposite sidewalls of the base 31. The plurality of reflecting units 21 extend from the fixing part toward the side where the light source 10 is located. The structure is simple and easy to assemble. The circuit board 12 and the reflector 20 are preferably configured separately without contact to facilitate maintenance and replacement. When the light from the light source 10 is projected toward the reflector 20, the headlight 1 can produce light spots of different densities and a soft halo effect due to the structural design of the reflector 20 and the arrangement of the plurality of light sources 10.
