Description

Technical FieldThe present invention relates to a vehicle lamp, and more particularly to a vehicle lamp having a reflection structure.Prior ArtConventional vehicle lights, such as, but not limited to, headlights, stop lights, daytime running lights, etc., include a housing, a light source disposed in the housing, and a reflective structure surrounding the light source. The reflection structure is used to change the transmission path of the light of the light source to achieve a desired light effect. However, conventional vehicle lamps produce different light effects by changing the number, distribution, brightness, or configuration of the reflection structure of the light source. The design of the reflective structure and the light effect it produces are limited and not variable. There are also problems such as high cost, lack of precision and trouble in assembly during production and processing, which must be improved urgently.Therefore, it is necessary to provide a novel and advanced vehicle lamp in order to solve the above problems.Object of the InventionThe object of the invention is to provide a vehicle lamp which can produce specific light effects and has a reflection structure with a greater production tolerance.This object is achieved by the vehicle lamp of the invention, comprising: a light source used for emitting light; and a reflector having at least one reflection unit for receiving and reflecting the light, the at least one reflection unit including a plurality of light guide blocks arranged in a matrix, each of the light guide blocks having a reflection surface; wherein the plurality of light guide blocks include the first light guide blocks, the second light guide blocks, and the third light guide blocks, the first light guide blocks and the third light guide blocks being adjacent to the second light guide blocks, wherein there is a first difference in height between the reflection surfaces of the first light guide blocks and the reflection surfaces of the second light guide blocks, and a second difference in height between the reflection surfaces of the second light guide blocks and the reflection surfaces of the third light guide blocks, wherein the first difference in height is different from the second difference in height.Brief Description of the DrawingsFIG. 1 is a perspective view of the preferred embodiment of the invention, FIG. 2 is an exploded view of the preferred embodiment of the invention, FIG. 3 is an exploded view from another viewing direction of the preferred embodiment of the invention, FIG. 4 is a perspective view of the reflector of the preferred embodiment of the invention, FIG. 5 is an enlarged view according to FIG. 4, FIG. 6 is a side view of the reflector of the preferred embodiment of the invention, FIG. 7 is a sectional view of the preferred embodiment of the invention.WAYS OF CARRYING OUT THE INVENTIONThe following embodiments are provided to illustrate the possible practice of this invention only, but are not intended to limit the scope of the invention. The term "one" or "at least one" preceding the substantives mentioned in the article has no limiting meaning for the amount. Depending on requirements, a "plurality" is also possible. Variations of this number are also within the scope of the invention.Figs. 1 to 7 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.The light source 10 is used for emitting light. The reflector 20 has at least one reflection unit 21 for receiving and reflecting the light. The at least one reflection unit 21 includes a plurality of light guide blocks 211 arranged in a matrix. Each of the light guide blocks 211 has a reflecting surface 212. The plurality of light guide blocks 211 include the first light guide blocks 211 a, the second light guide blocks 211 b, and the third light guide blocks 211 c. The first light guide blocks 211 aand the third light guide blocks 211 care adjacent to the second light guide blocks 211 b. There is a first difference in height between the reflection surfaces 212 of the first light guide blocks 211 aand the reflection surfaces 212 of the second light guide blocks 211 b, and there is a second difference in height between the reflection surfaces 212 of the second light guide blocks 211 band the reflection surfaces 212 of the third light guide blocks 211 c. The first height difference is different from the second height difference. As a result, the reflection surfaces 212 of the plurality of light guide blocks 211 are discontinuous and can reflect the light in multiple directions, thereby creating irregular light spots and mild halo effect.Preferably, each of the light guide blocks 211 has a rectangular outer contour. In the front view of the reflector 20, the light guide blocks 211 are juxtaposed to form a plurality of longitudinal lines 213 and a plurality of transverse lines 214 vertically intersecting each other as shown in FIG. 6. The plurality of light guide blocks 211 can be manufactured with, for example, a mold, whereby the manufacturing and design are simple and convenient. Each of the reflective surfaces 212 may be a planar surface, a convex surface, a concave surface, or a plurality of irregularly cut surfaces. They can be designed as required to produce different light effects.In this embodiment, the plurality of light guide blocks 211 have the same cross-sectional size. The first light guide blocks 211 a, the second light guide blocks 211 b, and the third light guide blocks 211 care continuously arranged in the same row or column. Preferably, the height differences between the reflection surface 212 of at least one light guide block 211 and the reflection surfaces 212 of four adjacent light guide blocks 211 are all different. Each of the light guide blocks 211 also has a plurality of side surfaces 218 laterally adjacent to the reflecting surface 212. The plurality of side surfaces 218 serve to reflect the light so that the light may generate mutual interference or multiple reflection, resulting in a better reflection effect.More specifically, the reflector 20 includes a plurality of reflection units 21 connected to each other. Between two adjacent substrates 215 is formed a ridge 216. The plurality of light guide blocks 211 are integrally arranged on the concave side 217 of the substrate 215, thereby achieving a good light receiving and collecting effect. The light source 10 comprises a plurality of light emitting elements 11 and a circuit carrier 12. Each of the light emitting elements 11 faces a reflection unit 21 and is offset from the ridge 216. The number of the reflection units 21 is equal to the number of the light emitting elements 11, so that the light from each of the light emitting elements 11 can be accurately radiated into the concave side 217. Each of the substrates 215 extends in an arc shape along a longitudinal direction L and a transverse direction H transverse to the longitudinal direction L, so that the reflecting surfaces 212 have a substantially concave shape, thereby producing a light scattering effect.Note that the vehicle lamp 1 of the present invention generates different interference and reflectances for the light by the different height differences between the reflecting surfaces 212 and the curvature of the substrates 215, thereby achieving a specific light effect. Even if there is a slight deviation in the accuracy of the height differences between the reflecting surfaces 212, a similar effect can still be obtained. Therefore, the production tolerance is larger, which facilitates production.The vehicle lamp 1 further includes a housing 30. the housing 30 has a base 31 and a light cover 32 that covers the base 31. The reflector 20 further includes a fixing portion 22 connected to one side of at least one reflection unit 21. The light source 10 and the fixing portion 22 are positioned on two opposite side walls of the base 31. The plurality of reflection units 21 extend from the mounting portion 22 toward a side where the light source 10 is provided, whereby the structure is simple and the assembly is easy. The circuit carrier 12 and the reflector 20 are preferably separately arranged without contacting each other to facilitate maintenance and replacement. When the light from the light source 10 is irradiated toward the reflector 20, the vehicle lamp 1 can generate light spots having different density and a mild halo effect due to the structural design of the reflector 20 and the configuration of the plurality of light sources 10.The invention thus relates to a vehicle lamp comprising: a light source (10) used for emitting light; and a reflector (20) having at least one reflection unit (21) for receiving and reflecting the light, the at least one reflection unit (21) including a plurality of light guide blocks (211) arranged in a matrix, each of the light guide blocks (211) having a reflection surface (212); wherein the plurality of light guide blocks (211) include the first light guide blocks (211a), the second light guide blocks (211b), and the third light guide blocks (211c), wherein the first light guide blocks (211a) and the third light guide blocks (211c) are adjacent to the second light guide blocks (211b), wherein there is a first difference in height between the reflection surfaces (212) of the first light guide blocks (211a) and the reflection surfaces (212) of the second light guide blocks (211b), and a second difference in height between the reflection surfaces (212) of the second light guide blocks (211b) and the reflection surfaces (212) of the third light guide blocks (211c), wherein the first difference in height is different from the second difference in height.List of reference characters1 Vehicle lamp 10 Light source 11 Light emitting element 12 Circuit substrate 20 Reflector 21 Reflection unit 211 Light guide block 211 aFirst light guide block 211 bSecond light guide block 211 cThird light guide block 212 Reflection surface 213 Longitudinal line 214 Transverse line 215 Substrate 216 Ridge 217 Concave side 218 Side surface 22 Mounting portion 30 Housing 31 Base 32 Light cover L Longitudinal direction H Transverse direction
