For this purpose, the utility model provides a vehicle lamp, which can diffuse light outward through a first reflecting surface and a second reflecting surface, has a large irradiation range and high safety.

[0004] The utility model also provides a vehicle with the above vehicle lamp.

[0005] The vehicle lamp according to the first aspect embodiment of the utility model includes a mounting base, a light-transmitting plate and a reflector cover. The mounting base is used for mounting a light source assembly, and the mounting base is a trough-shaped structure with an opening on one side. The light-transmitting plate is connected to the mounting base to close the opening. The reflector cover is connected to the mounting base and is located between the light-transmitting plate and the mounting base.

[0028] Traditional vehicle headlights often use simple reflectors, mostly with conical smooth walls, which have a poor effect on expanding the light, with limited light diffusion effect and are difficult to meet the lighting requirements of modern vehicles for high brightness and wide illumination range. Especially in complex and changeable road environments, such as at night, in rainy and foggy weather, etc., the problems of uneven light distribution and insufficient illumination range of traditional vehicle headlights are particularly prominent, posing safety hazards to drivers.

[0029] Therefore, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a vehicle headlight proposed by the present utility model includes a mounting base 100, a light-transmitting plate 300 and a reflector 200. The mounting base 100 is used to mount a light source assembly, and the mounting base 100 is a trough-shaped structure with an opening 101 on one side. The light-transmitting plate 300 is connected to the mounting base 100 to close the opening 101. The reflector 200 is connected to the mounting base 100 and is located between the light-transmitting plate 300 and the mounting base 100. The reflector 200 is provided with a penetrating diffusion groove 230 for the light emitted by the light source assembly to pass through. The inner diameter of the diffusion groove 230 increases from the side close to the mounting base 100 towards the side close to the light-transmitting plate 300. The groove wall of the diffusion groove 230 is provided with a plurality of adjacent first reflecting surfaces and second reflecting surfaces, and the second reflecting surface is located on the outermost side close to the light-transmitting plate 300. The angle between the first reflecting surface and the axis of the diffusion groove 230 is smaller than the angle between the second reflecting surface and the axis of the diffusion groove 230.

[0030] It can be understood that the vehicle headlight specifically includes three main parts: a mounting base 100, a light-transmitting plate 300 and a reflector 200. The mounting base 100, as a support structure, has an opening 101 on one side for mounting a light source assembly, such as an LED lamp bead 500 or a halogen bulb. The mounting base 100 is designed as a trough-shaped structure for easy fixation and heat dissipation. The light-transmitting plate 300 is tightly connected to the opening 101 of the mounting base 100, playing a role in closing and protecting the light source assembly, while allowing light to pass through. The light-transmitting plate 300 can be made of materials with high light transmittance and wear resistance, such as tempered glass or high-transparency plastic, to ensure efficient light transmission and the durability of the lamp.

[0031] It should be noted that a through diffusion groove 230 is provided inside the reflector 200. The inner diameter of the diffusion groove 230 gradually increases from the side close to the mounting base 100 to the side of the light-transmitting plate 300, forming a conical or similar shape, which is conducive to the gradual diffusion and direction change of light in the diffusion groove 230. Specifically, a plurality of adjacent first reflecting surfaces and second reflecting surfaces are provided on the groove wall of the diffusion groove 230. The first reflecting surface is located on the side close to the mounting base 100, and the angle between it and the axis of the diffusion groove 230 is small, mainly used for initially guiding the light to be reflected inside the diffusion groove 230. The second reflecting surface is located on the outermost side close to the light-transmitting plate 300, and the angle between it and the axis of the diffusion groove 230 is large, which can further diffuse the light after the initial reflection. Due to the difference in the angle between the first reflecting surface and the second reflecting surface, after multiple reflections of the light in the diffusion groove 230, the light can be emitted at a wider angle, forming a larger irradiation range. Through the synergistic effect of the first reflecting surface and the second reflecting surface, the efficient diffusion of light is achieved, significantly expanding the irradiation range of the vehicle lamp, improving the visibility and safety of night driving. The design of the diffusion groove 230 of the reflector 200 makes the light evenly distributed in multiple directions, reducing the obvious spot effect of light and dark contrast, and improving the visual comfort.

[0032] Specifically, in some embodiments, the angle between the outermost light of the expanded light column and the center line can reach 80°, significantly improving the illumination range and the uniformity of light distribution of the vehicle lamp, being very suitable for use on vehicle lamps, and effectively improving the safety and comfort of night driving.

[0033] Referring to Figure 2 , in order to achieve precise control and efficient utilization of light, the light source assembly in the present utility model is composed of a circuit board and a plurality of lamp beads 500. These lamp beads 500 are evenly distributed on the circuit board, and each lamp bead 500 corresponds to the position of the diffusion groove 230 on the reflector 200 one by one. This design ensures that the light emitted by each lamp bead 500 can directly enter the corresponding diffusion groove 230, and the best light diffusion effect is achieved through the action of the reflecting surface.

[0034] Specifically, the reflector 200 is designed in a circular shape, and a plurality of diffusion grooves 230 are radially arranged on its surface from the center to the outside. This layout is not only beautiful but also can make full use of the surface area of the reflector 200, enabling the light to be evenly diffused in multiple directions and further increasing the irradiation range of the vehicle lamp.

[0035] To fix the reflector 200 and the mounting base 100, fixing clamping platforms 210 are provided on the peripheral side wall of the reflector 200. These clamping platforms can be easily clamped at the corresponding positions on the mounting base 100 to achieve a quick and stable connection. Moreover, the reflector 200 is connected by ultrasonic welding, which is convenient for users to quickly fix and install the reflector 200.

[0036] Reference Figure 1 and Figure 3 Furthermore, in a specific implementation, four fixing chucks 210 are arranged along the circumferential side wall of the reflector 200, and two positioning slots 220 are arranged and disposed opposite to each other. Two fixing chucks 210 are adjacently arranged on both sides of each positioning slot 220. Such a layout not only ensures the stability of the connection but also facilitates quick installation.

[0037] Reference Figure 1 and Figure 2 The light-transmitting plate 300 is inserted into the installation groove on the mounting base 100 through the side plate 310 provided around its circumference, realizing the fixed installation of the light-transmitting plate 300 and the mounting base 100. This design simplifies the installation process and at the same time ensures the sealing between the light-transmitting plate 300 and the mounting base 100.

[0038] Reference Figure 4 To protect the internal structure of the vehicle lamp from the influence of the external environment, the present utility model also provides a soft protective sleeve. The protective sleeve is in the shape of a conical cylinder and is sleeved outside the mounting base 100. Its material is soft and has a certain elasticity, and it can closely fit the mounting base 100 to provide effective protection. Specifically, on the inner side wall of the soft protective sleeve, near the narrow end of its inner diameter, an annular fixing groove 410 is provided. At the same time, a fixing rib 110 is provided on the outer side wall of the mounting base 100. By inserting the fixing rib 110 into the annular fixing groove 410, the connection between the soft protective sleeve and the mounting base 100 can be further fixed, improving the overall stability.

[0039] It should be noted that the mounting base 100 is also cylindrical. During packaging and transportation, to prevent damage to the light source assembly, the light-transmitting plate 300 is usually sleeved upward in the soft protective sleeve. At this time, the annular fixing groove 410 and the fixing rib 110 are misaligned with each other, and the thicker part of the soft protective sleeve wraps the mounting base 100, thereby optimizing the protection effect and preventing damage during transportation. During use, the light-transmitting plate 300 is sleeved downward in the soft protective sleeve. At this time, the fixing rib 110 corresponds to the annular fixing groove 410 and is inserted, completing the fixed connection between the mounting base 100 and the soft protective sleeve and completing the assembly. It should be noted that in addition to being beneficial for packaging and transportation, the soft protective sleeve also provides an additional protective layer for the vehicle lamp during use, effectively resisting the erosion and impact of the external environment.

[0040] The present utility model also proposes a vehicle including the above vehicle lamp structure. By adopting the above vehicle lamp, the vehicle can significantly improve the safety and lighting effect of night driving, providing a more comfortable driving experience for the driver. It should be noted that the vehicle proposed by the present utility model includes but is not limited to trucks, automobiles, and motorcycles.

[0041] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
