Description

Technical Field

[0001] The utility model relates to the technical field of automobile license plate lamps, in particular to an anti-glare automobile license plate lamp. Background Art

[0002] A license plate light is a lamp installed above the license plate at the rear of a car. It is mainly used to illuminate the license plate at night or when it is dark so that other vehicles and pedestrians can clearly see the license plate number. This light is usually turned on together with small lights such as the driving position to serve as lighting and decoration. The license plate light plays an important role in traffic safety. At night or in dim light conditions, it can ensure that other drivers and pedestrians can clearly see the vehicle's license plate information, which helps maintain traffic order and reduce the occurrence of traffic accidents.

[0003] Common license plate lights basically install two symmetrical license plate lights above the license plate to achieve the purpose of illuminating the license plate. However, most of the existing license plate lights use the method of directly shining the light emitted by the bulb onto the license plate for lighting, which will cause the problem of partial over-brightness of the license plate, thereby easily causing glare to the rear drivers. In order to solve the glare problem, a general license plate light will add a refraction plate at the bottom to solve the glare problem by scattering the light.

[0004] However, since the installation position and transmittance of the refraction plate are fixed in this method, the illumination quality of the light is fixed. Even if the brightness of the lamp is increased, the refractive index, light intensity distribution, dispersion effect, and spot shape and size of the light irradiated to the license plate cannot be adjusted. As a result, the license plate light cannot adapt well to the requirements for license plate brightness under various driving environments and cannot meet the working requirements of the license plate light. Therefore, an anti-glare license plate light is proposed. Utility Model Content

A connecting shaft 8 is inserted into the middle of the inner cavity of the connecting shell 7, and the left end of the connecting shaft 8 passes through the interior of the protective shell 2. Please refer to Figure 4 , a motor 9 is installed on the upper part of the inner cavity of the protective shell 2;

[0033] See also Figure 3 The first bevel gear 10 is mounted on the outside of the connecting shaft 8 at a position corresponding to the triangular transparent prism 6. Figure 6 The rear ends of the triangular transparent prisms 6 are connected to the rotating shaft 11, and the rear ends of the rotating shaft 11 are coaxially connected to the second bevel gear 12, and the second bevel gear 12 is meshed with the first bevel gear 10, see Figure 2 The number of triangular transparent prisms 6 is 8-12 groups, the roughness of the three surfaces of the triangular transparent prisms 6 are different from each other, and the front ends of the triangular transparent prisms 6 are movably connected to the corresponding positions of the inner cavity of the mounting housing 1 through bearings, please refer to Figure 5 The left end of the connecting shaft 8 passes through the bottom of the inner cavity of the protective shell 2, and the left and right ends of the connecting shaft 8 are movably connected to the corresponding positions of the inner cavities of the protective shell 2 and the connecting shell 7 through ball bearings;

[0034] See also Figure 7The mounting frame 14 is coaxially connected to the outer end of the rotor of the motor 9, a turntable 15 is installed on the right side of the mounting frame 14, and a lever 16 is connected to the outer end of the right side of the mounting frame 14. A triangular transmission plate 13 is installed on the outer side of the shaft body of the connecting shaft 8 at a position below the turntable 15. Transmission grooves 132 are provided at the inner convex corners of the triangular transmission plate 13, and the groove bottoms of the transmission grooves 132 are all arc-shaped. The rotation of the mounting frame 14 and the turntable 15 is driven by the motor 9, so that the rotation of the triangular transmission plate 13 can be driven by the lever 16, so that the rotation of the second bevel gear 12 can be driven by the connecting shaft 8 and the first bevel gear 10, so that the three The three-sided conversion of the triangular transparent prism 6 facilitates the scattering of light through the three faces of the triangular transparent prism 6 with different roughness, so that the refractive index of the light (due to the different roughness of the three faces, the transmittance is different, and their refractive index of the light may also be different. The refractive index describes the change in speed when the light enters another medium from one medium, thereby causing the change in the direction of the light. The faces with different transmittances will cause the light to be refracted to different degrees when passing through the prism, causing the propagation direction of the light to be deflected differently) and the light intensity distribution (different transmittances will cause the light on different faces to be different). Uneven distribution of line intensity: surfaces with higher transmittance allow more light to pass through, while surfaces with lower transmittance block some light, which causes the light intensity to be unevenly distributed in space after passing through the prism), dispersion effect (surfaces with different transmittances may have different refractive abilities for light of different colors, which may make the dispersion effect more obvious or weakened. Dispersion refers to the phenomenon that different color components in light are separated due to different refractive indices when passing through a medium. Differences in transmittance may aggravate or weaken this dispersion effect), and changes in the shape and size of the light spot (when light passes through a triangular transparent prism, due to different The difference in light transmittance of the surfaces may also affect the shape and size of the final light spot. The surface with higher light transmittance may make the light spot brighter or larger, while the surface with lower light transmittance may make the light spot darker or smaller), thereby improving the illumination quality of the license plate. At the same time, the scattered light avoids the glare problem caused by concentrated illumination, and adapts to the requirements of license plate illumination brightness under different driving environments, thereby improving the use quality of the license plate lamp. The diameter of the transmission groove 132 is matched with the lever 16, and the three outer sides of the triangular transmission plate 13 are provided with arc-shaped recesses 131, and the arc of the arc-shaped recess 131 is matched with the outer periphery of the turntable 15.

Under the influence of different light transmittance, the refractive index, light intensity distribution, dispersion effect, and spot shape and size of the light will be affected, thereby improving the illumination quality of the license plate. At the same time, the scattered light avoids the glare problem caused by concentrated illumination, and adapts to the requirements for license plate illumination brightness under different driving environments, thereby improving the use quality of the license plate lamp.
