[0027] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0028] Reference below Figure 1-Figure 5 A license plate lamp 1 according to an embodiment of the utility model is described, and the license plate lamp 1 is applied to a vehicle.

[0029] like Figure 1-Figure 4 As shown, according to the utility model, the license plate light 1 includes: a lampshade 2, a light source body 3 and a lampshade panel 4. The light source body 3 is arranged in the lampshade 2, and the lampshade panel 4 is arranged at one end of the lampshade 2. The lampshade panel 4 is provided with a diverging portion 41 and a reflecting portion 42. The diverging portion 41 is arranged corresponding to the light source body 3 to diverge the light transmitted by the light source body 3, and the reflecting portion 42 is arranged on at least one side of the diverging portion 41 to reflect the light transmitted by the light source body 3.

[0030] It can be understood that the lampshade 2, the light source body 3 and the lampshade panel 4 constitute the main structure of the license plate lamp 1. The light source body 3 is located in the lampshade 2, so that the lampshade 2 can protect the light source body 3, thereby preventing the light source body 3 from being subjected to force and extending the service life of the light source body 3. The light source body 3 transmits light downward, so that the light of the light source body 3 can be irradiated on the license plate 5. The lampshade panel 4 is located at the lower end of the lampshade 2, so that the light of the light source body 3 can be irradiated on the license plate 5 through the lampshade panel 4. The lampshade panel 4 is provided with a diverging portion 41 and a reflecting portion 42, and the diverging portion 41 and the reflecting portion 42 are located below the light source body 3, so that the light transmitted by the light source body 3 can be irradiated on the license plate 5 after being diverged by the diverging portion 41 and reflected by the reflecting portion 42, thereby improving the lighting effect of the license plate lamp 1 on the license plate 5. For example, the light source body 3 can be an LED lamp, so that the lighting effect can be improved.

[0031] Therefore, by setting a lampshade panel 4 at one end of the lampshade 2, and setting a diverging part 41 and a reflecting part 42 on the lampshade panel 4, the light transmitted by the light source 3 can be diverged through the diverging area and reflected through the reflecting area, thereby avoiding the occurrence of light spots and meeting the lighting distribution requirements, thereby improving the lighting effect of the license plate light 1 on the license plate 5.

[0032] Among them, Figure 2 and Figure 3 As shown, the diverging portion 41 is configured as a concave lens 44 in the first direction, and the first direction is parallel to the length direction of the license plate light 1. That is, the first direction is the left-right direction of the license plate light 1, and the concave lenses 44 are arranged at the left and right ends of the diverging portion 41, and the concave lenses 44 are located below the left and right ends of the light source body 3, so that the light transmitted by the light source body 3 can be diverged through the concave lenses 44, thereby increasing the area of ​​the light transmitted by the light source body 3 irradiating the license plate 5.

[0033] In addition, if Figure 2 and Figure 3 As shown, the diverging portion 41 is configured as a convex lens 43 in the second direction, and the second direction is perpendicular to the first direction and the thickness direction of the lampshade panel 4. It can be understood that the second direction is the longitudinal direction of the vehicle, the convex lens 43 is located between the concave lenses 44, and the convex lens 43 is located directly below the light source body 3, so that the light transmitted by the light source body 3 can be converged through the concave lens 44, and then the light transmitted by the light source body 3 can be concentrated on the license plate 5. Such an arrangement can make the concave lens 44 and the convex lens 43 form an elliptical area, so that the light transmitted by the light source body 3 can be irradiated below and then diverged to the left and right directions, thereby avoiding the occurrence of light spots, and then improving the lighting effect of the license plate lamp 1 on the license plate 5.

[0034] In particular, if Figure 2 and Figure 3 As shown, there are multiple light sources 3 and multiple diverging parts 41. The multiple light sources 3 are spaced apart in the first direction and correspond to the multiple diverging parts 41 one by one. The first direction is parallel to the length direction of the license plate. In other words, there are at least two light sources 3 and emitting parts. The two light sources 3 are spaced apart in the left and right of the lampshade 2, so that more light can be transmitted. Each diverging part 41 is located below each light source 3, so that the diverging part 41 can diverge and converge the light transmitted by the light source 3, thereby increasing the area where the light transmitted by the light source 3 irradiates the license plate 5 and concentrating the light transmitted by the light source 3 on the license plate 5.

[0035] In addition, if Figure 2 and Figure 3As shown, the reflective portion 42 includes a right-angle prism 45, and the right-angle prism 45 extends along the side edge of the diverging portion 41. It can be understood that the right-angle prism 45 is located at one end of the concave lens 44 away from the convex lens 43, and one end of the right-angle prism 45 is located at both ends of the longitudinal direction of the diverging portion 41. This arrangement can make the right-angle prism 45 change the traveling direction of the light, so that the light diverged from the diverging portion 41 can travel in a specific area, thereby meeting the light distribution requirements.

[0036] Among them, Figure 2 and Figure 3 As shown, the reflective portion 42 includes at least two right-angle prisms 45, and the at least two right-angle prisms 45 are arranged in sequence in a direction away from the diverging portion 41. That is, the two right-angle prisms 45 are arranged at intervals in the longitudinal direction, and one end of one of the right-angle prisms 45 is connected to one end of the diverging portion 41 in the longitudinal direction, so that the continuity between the diverging portion 41 and the reflective portion 42 can be met, thereby improving the lighting effect and meeting the light distribution requirements.

[0037] In particular, if Figure 3 As shown, there are multiple reflective parts 42, and the multiple reflective parts 42 are arranged around the divergent part 41. For example, four reflective parts 42 are respectively located at the left front end, the left rear end, the right front end and the right rear end of the divergent part 41, and each emitting part is provided with two right-angle prisms 45, so that the eight right-angle prisms 45 can conduct the light diverged from the divergent part 41 to a specified area, thereby meeting the slow light requirement.

[0038] In addition, if Figure 2 and Figure 3 As shown, the diverging portion 41 and the reflecting portion 42 are integrally formed on the side surface of the lampshade panel 4 facing the light source body 3. This arrangement can reduce the number of parts and components, thereby improving productivity. In addition, the lampshade panel 4 is produced by injection molding, thereby ensuring better fluidity and productivity, thereby improving the yield rate of parts and components and saving costs without causing process defects such as injection shrinkage marks.

[0039] In addition, Figure 5As shown, the minimum value of the thickness of the divergent portion 41 is d1 and the maximum value is d2, and d1 and d2 satisfy the relationship: 1.5mm≤d1≤1.6mm, 3.8mm≤d2≤4.0mm; the minimum value of the thickness of the reflective portion 42 is d3 and the maximum value is d4, and d3 and d4 satisfy the relationship: 1.7mm≤d3≤1.8mm, 2.6mm≤d4≤2.7mm. It can be understood that the thickness of the divergent portion 41 and the reflective portion 42 should be within a reasonable range. If the minimum value of the thickness of the divergent portion 41 is less than 1.5mm, greater than 1.6mm, and the maximum value is less than 3.8mm, and the maximum value is greater than 4mm, and the minimum value of the thickness of the reflective portion 42 is less than 1.7mm, greater than 1.8mm, and the maximum value is less than 2.6mm, and greater than 2.7mm, this will cause process defects such as injection shrinkage marks to appear on the lampshade panel 4, thereby affecting the light distribution requirements and the yield rate of components, and thus causing cost waste. For example, the basic material thickness of the existing lampshade panel 4 is 1.8mm. Due to the light distribution characteristics, the material thickness will continue to increase, and process defects such as shrinkage marks will be generated during the injection molding process, thereby reducing the yield rate. The lampshade panel 4 in the present technical solution can move the light distribution characteristics downward by 0.25mm as a whole, that is, the maximum thickness of the divergent part is 3.9mm, and the minimum is 1.55mm. The maximum thickness of the reflective part is 2.63mm, and the minimum is 1.75mm, thereby avoiding process defects such as injection molding shrinkage marks.

[0040] The vehicle according to the embodiment of the utility model includes: a license plate 5 and the license plate light 1 of the above embodiment, and the optical axis of the light source body 3 is set at a certain angle to the license plate 5, so as to avoid the occurrence of light spots and meet the lighting requirements, thereby improving the lighting effect of the license plate light 1 on the license plate 5.

[0041] Among them, Figure 1 As shown, the ratio of the distance from the light source body 3 to the surface of the divergent part 41 to the distance from the surface of the divergent part 41 to the license plate 5 is k, and k satisfies the relationship: 1 / 25≤k≤1 / 28. For example, the ratio of the distance from the light source body 3 to the surface of the divergent part 41 to the distance from the surface of the divergent part 41 to the license plate 5 is 1 / 26.5, the distance between the light source body 3 and the surface of the divergent part 41 is about 4.5 mm, and the distance from the surface of the divergent part 41 to the license plate 5 is about 119.5 mm, thereby avoiding the occurrence of light spots and meeting the lighting distribution requirements.
