[0024] The present invention provides a vehicle lamp 100 , which can be installed on various vehicles requiring the vehicle lamp 100 , such as cars, off-road vehicles, and electric vehicles.

[0025] See also Figure 1 and Figure 2The vehicle lamp 100 proposed in the present invention includes a housing 1, a radiator 2 and a light source assembly. The radiator 2 is arranged in the housing 1. The light source assembly includes a first light source 3 and a second light source 4. The first light source 3 and the second light source 4 are both mounted on the radiator 2.

[0026] The light source assembly in the present headlight 100 includes a first light source 3 and a second light source 4, wherein the first light source 3 can be used to emit a high beam so that the headlight 100 can be used as a headlight, and the second light source 4 can be used to emit a low beam so that the headlight 100 can be used as a turn signal or a reverse light 100. Conventional headlights 100 usually have the first light source 3 and the second light source 4 dispersedly arranged, and in order to achieve heat dissipation for the first light source 3 and the second light source 4, multiple groups of heat sinks are usually provided to dissipate heat for different light sources. Unlike conventional headlights 100, the present headlight 100 installs the first light source 3 and the second light source 4 on a single radiator 2, and thus heat dissipation for the first light source 3 and the second light source 4 can be achieved through a single radiator 2, which makes the design of the headlight 100 more compact and helps to reduce the volume of the headlight 100.

[0027] In one embodiment, the first light source 3 includes a first lamp board and first lamp beads arranged on the first lamp board, and a side of the first lamp board facing away from the first lamp beads is arranged in contact with the heat sink 2 .

[0028] Similarly, the second light source 4 includes a second lamp board and second lamp beads arranged on the second lamp board, and a side of the second lamp board facing away from the second lamp beads is arranged in contact with the heat sink 2 .

[0029] The first and second light boards are both PCBs, and the first and second lamp beads include, but are not limited to, LED, halogen, and xenon lamp beads. The sides of the first and second light boards facing away from the lamp beads are positioned in contact with the heat sink 2, and both can be fixed to the heat sink 2 using screws. This allows heat generated by the lamp beads to be directly transferred to the heat sink 2 through the light boards, thereby achieving rapid heat dissipation from the lamp beads and the light boards.

[0030] Furthermore, the housing 1 of the vehicle lamp 100 includes a bottom shell 11 and an upper cover 12 covering the bottom shell 11. The upper cover 12 has a light-transmitting opening 121. The light source assembly also includes a first optical cup 5 having a light outlet. The first optical cup 5 covers the first light source 3 and is fixedly connected to the heat sink 2, such as by screws, with the light outlet facing the light outlet 121. Light emitted by the first lamp bead is reflected by the first optical cup 5 and then emitted through the light outlet and light outlet 121. In this embodiment, the first optical cup 5 is used to reflect and focus the light emitted by the first lamp bead, thereby ensuring that the lighting effect of the first lamp bead meets the requirements of vehicle lighting regulations.

[0031] Specifically, to facilitate installation of the first light board, the heat sink 2 is provided with a first mounting location having a bearing surface 21 for contact with the first light board. The bearing surface 21 is tilted away from the light outlet. The first optical cup 5 has a reflective surface opposite the bearing surface 21, and the reflective surface and the bearing surface 21 are arranged at an angle. The first light board is mounted on the bearing surface 21, and the light emitted by the first lamp beads is reflected by the reflective surface and emitted through the light outlet.

[0032] In order to avoid interference between the first lamp board and the second lamp board, the first lamp board and the second lamp board are respectively arranged on different sides of the radiator 2. In the embodiment shown in the figure, the second lamp board is fitted on the side of the radiator 2 facing the light outlet, and the first lamp board is fitted on the top or bottom surface of the radiator 2, so as to maximize the use of the heat dissipation area of the radiator 2 and improve the utilization rate of the radiator 2.

[0033] In one embodiment, the light source assembly also includes a second light cup 6, which is covered on the second lamp panel and fixedly connected to the heat sink 2, such as by screws. The second light cup 6 is used to adjust the light type emitted by the second lamp bead so that the brightness and color temperature of the light emitted by the second lamp bead meet the requirements of lighting regulations.

[0034] The vehicle lamp 100 also includes a control motherboard 7, which is mounted on the side of the radiator 2 facing away from the second light board. The control motherboard 7 is electrically connected to the first and second light boards and is used to control the on / off operation of the first and second lamp beads. The radiator 2 dissipates heat not only from the first and second light sources but also from the control motherboard 7, further improving the heat dissipation efficiency of the radiator 2. Furthermore, the heat sources within the vehicle lamp 100 are concentrated around the periphery of the radiator 2, reducing the overall size of the vehicle lamp 100 and resulting in a more compact design.

[0035] In one embodiment of the present utility model, the vehicle lamp 100 further includes a lampshade 8, which is disposed between the bottom shell 11 and the upper cover 12. The lampshade 8 is provided with a first light-transmitting area and a second light-transmitting area. The first light-transmitting area and the second light-transmitting area are disposed in an enclosed area of a light-transmitting port 121. The first light-transmitting area is a transparent area, and the second light-transmitting area is provided with a texture. The light emitted by the first light source 3 is emitted through the first light-transmitting area and the light-transmitting port 121, and the light emitted by the second light source 4 is emitted through the second light-transmitting area and the light-transmitting port 121.

[0036] Among them, the material of the lampshade 8 is a light-transmitting material such as PC plastic or glass, and the lampshade 8 is set to optimize the light emitted by the first lamp body and the second lamp body. Specifically, the lampshade 8 is provided with a first light-transmitting area and a second light-transmitting area. The coverage range of the first light-transmitting area is the radiation range of the light of the first lamp bead. The first light-transmitting area is a transparent area, thereby allowing the light emitted by the first lamp bead to pass directly, so that it is suitable for occasions requiring clear and bright lighting, such as high beams. The coverage range of the second light-transmitting area is the radiation range of the light of the second lamp bead. The second light-transmitting area is provided with a texture. This texture can be a scattered light or light-guiding structure, which is used to adjust the distribution of light. It is suitable for occasions requiring soft or specific light type lighting, such as low beams, turn signals or reversing lights 100, etc., so as to adapt to different lighting modes.

[0037] In order to facilitate the installation of the vehicle lamp 100 on the vehicle, the vehicle lamp 100 further includes a bracket assembly 9 . The bracket assembly 9 is installed on the peripheral side of the housing 1 and is used to install the vehicle lamp 100 on the vehicle.

[0038] In the embodiment shown in the figure, the bracket assembly 9 includes a left bracket 91, a right bracket 92, and a rear bracket 93. The left bracket 91 and the right bracket 92 are respectively mounted on opposite sides of the housing 1. The rear bracket 93 is mounted on the side of the housing 1 facing away from the light outlet and is fixedly connected to the left bracket 91 and the right bracket 92. The symmetrical design of the left bracket 91 and the right bracket 92 can effectively balance the weight and force of the vehicle lamp 100. The three-bracket design can provide all-round support for the vehicle lamp 100 and ensure the stability of the vehicle lamp 100 when installed.

[0039] The present invention also proposes a vehicle, which may be a car, an off-road vehicle, and an electric vehicle. The vehicle includes a headlight 100.
