[0030] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] like Figures 1 to 5 As shown, the embodiment of the utility model provides an anti-glare automotive LED lamp, including a lamp holder 10, a first reflector 21, a second reflector 22, a low-beam LED lamp bead 31, a high-beam LED lamp bead 32, a light-transmitting mirror 40 and a lens fixing frame 50. The upper and lower ends of the surface of the lamp holder 10 are respectively provided with a first accommodating cavity 101 and a second accommodating cavity 102. The high-beam LED lamp bead 32 is arranged in the first accommodating cavity 101, and the low-beam LED lamp bead 31 is arranged in the second accommodating cavity 102. The high-beam LED lamp bead 32 is placed in the upper first accommodating cavity 101 so that the light beam emitted by it is irradiated forward and slightly upward, so as to provide long-distance lighting without interfering with oncoming vehicles. The low-beam LED lamp bead 31 is placed in the lower second accommodating cavity 102 so that the light beam emitted by it is mainly irradiated forward and slightly downward, so as to focus on the near front area of ​​the road, thereby reducing the risk of causing glare to oncoming vehicles.

[0034] The lens fixing frame 50 is arranged on the circumferential side wall of the lamp holder 10, and the lens fixing frame 50 is connected to the light transmitting mirror 40 to cover the light transmitting mirror 40 on the surface of the lamp holder 10. The surface of the light transmitting mirror 40 is provided with a prism structure 401, and the prism structure 401 is used to scatter the light emitted by the low-beam LED lamp beads 31 and the high-beam LED lamp beads 32; the light transmitting mirror 40 can diffuse the light emitted by the low-beam LED lamp beads 31 and the high-beam LED lamp beads 32, so that the light can be evenly distributed on the road, thereby improving the lighting effect; the prism structure 401 arranged on the light transmitting mirror 40 can better disperse the light, make the light distribution more even, reduce the light spot, improve the coverage and uniformity of the road lighting, and can effectively reduce the glare phenomenon, especially in the high-beam mode.

[0035] The first reflector 21 is attached to the first accommodating cavity 101, and the first reflector 21 is used to reflect the light emitted by the high-beam LED lamp bead 32 toward the lower area of ​​the light-transmitting mirror 40. The second reflector 22 is attached to the second accommodating cavity 102, and the second reflector 22 is used to reflect the light emitted by the low-beam LED lamp bead 31 toward the upper area of ​​the light-transmitting mirror 40. The high-beam LED lamp beads 32 need to provide long-distance lighting so that the driver can see farther at night or under conditions of poor visibility. The first reflector 21 can reflect the light of the high-beam LED downward to control the light to diffuse slightly downward to avoid the light directly entering the eyes of the oncoming driver, reduce glare, and ensure that the light is mainly concentrated on the road rather than the sky or the oncoming lane; the low-beam LED lamp beads 31 are used to illuminate the area near the front of the road to avoid the drivers of oncoming vehicles from being affected by glare. The second reflector 22 can reflect the light upward to ensure that the light is concentrated on the road surface, while enhancing the road lighting, reducing the possibility of direct light to other drivers; the setting of the first reflector 21 and the second reflector 22 can enable the high-beam and low-beam lights to be accurately guided to the required area, avoiding the light directly shining into the sight of oncoming vehicles or pedestrians, thereby effectively reducing the glare phenomenon.

[0036] like Figure 5 As shown, further, the first reflector 21 is a hemispherical structure, and the first reflector 21 includes a plane portion 211 and a curved portion 212, and the curved portion 212 is located above the plane portion 211, and the curved portion 212 is a C-shaped structure. With this arrangement, the first reflector 21 can adjust the diffusion angle of the light emitted by the high-beam LED lamp beads 32, ensuring that the light diffuses downward and slightly forward, so that the light is more concentrated on the road surface, thereby effectively illuminating the long-distance road without causing glare to oncoming vehicles.

[0037] like Figure 1 and Figure 4As shown, further, a sink 103 is provided between the first accommodating cavity 101 and the second accommodating cavity 102, and a reflective isolation plate 60 is provided in the sink 103, and the reflective isolation plate 60 is used to isolate the light emitted by the low-beam LED lamp bead 31 and the high-beam LED lamp bead 32. The light isolation plate can ensure that the light of the low-beam LED lamp bead 31 and the high-beam LED lamp bead 32 is only irradiated within its predetermined lighting area, avoiding the visual confusion that may be caused by the light; specifically, when switching from low beam to high beam, it can prevent the residual low beam from scattering to the area that should not be illuminated.

[0038] like Figure 4 As shown, further, the first reflector 21 and the second reflector 22 are symmetrically arranged around the axis of the reflective isolation plate 60. It should be noted that the function of the second reflector 22 is the same as that of the first reflector 21, and will not be described in detail here.

[0039] Furthermore, the reflective isolation plate 60 is made of aluminum. Aluminum has reflective properties and can effectively reflect light, so that the light is directed in the correct direction, and the light efficiency utilization rate is improved. In addition, the high-beam LED lamp beads 32 and the low-beam LED lamp beads 31 generate a lot of heat during operation, and the reflective isolation plate 60 made of aluminum can help dissipate heat, thereby extending the service life of the lamp beads.

[0040] like Figure 1 and Figure 3 As shown, further, avoidance grooves 402 are provided on both sides of the light-transmitting mirror 40, and baffle portions 501 adapted to the shape of the avoidance grooves 402 are provided on both sides of the lens fixing frame 50. The baffle portions 501 are used to position and clamp the light-transmitting mirror 40 to prevent it from loosening due to bumps or collisions during driving, and the structural stability is good.

[0041] Furthermore, the light-transmitting mirror 40 is made of silicone resin, polymethyl methacrylate or polycarbonate. In this embodiment, the light-transmitting mirror 40 is made of silicone resin, which has high light transmittance and can effectively transmit the light emitted by the high-beam LED lamp beads 32 and the low-beam LED lamp beads 31, reducing light loss, thereby providing a brighter lighting effect, and silicone resin has high flexibility and impact resistance, so that the light-transmitting mirror 40 is not easy to break or damage when subjected to slight impact or vibration.

[0042] like Figure 2 As shown, further, the light-transmitting mirror 40 is coated with an anti-reflection coating, which is a silicon dioxide coating. The silicon dioxide coating can reduce the reflectivity of the surface of the light-transmitting mirror 40 to reduce glare.

[0043] Furthermore, a positioning connecting column 104 is provided on the back of the lamp holder 10, and the cross-sectional area of ​​the positioning connecting column 104 gradually increases from the middle to both ends. The positioning connecting column 104 can be positioned and installed with a preset assembly interface on the car. The cross-sectional area of ​​the positioning connecting column 104 is gradually increased from the middle to both ends, so that a self-locking function is achieved when inserted into the corresponding interface, thereby increasing the friction and tightness of the connection.

[0044] Furthermore, the thickness of the light-transmitting mirror 40 is 2-5 mm. In this embodiment, the thickness of the light-transmitting mirror 40 is 2 mm.

[0045] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
