[0027] like Figures 1 to 5 As shown, a four-eye vehicle lamp of the utility model comprises a radiator 1, an LED light source 2, a lens integrated lens 3, and a lens fixing frame 4.

[0028] The radiator 1 is provided with a fixing platform 5, and the fixing platform 5 is provided with a limiting structure 6. The LED light source 2 is fixed to the fixing platform 5 through the limiting structure 6. The lens fixing frame 4 is connected to the fixing platform 5 and limits the LED light source 2 to the radiator 1, so that the LED light source 2 is fixed to the radiator 1.

[0029] The lens integrated lens 3 includes a plurality of light-transmitting and refractive parts 31 , and the LED light source 2 is provided with a plurality of light-emitting parts 21 corresponding to each light-transmitting and refractive part 31 .

[0030] When in use, each light emitting part 21 forms a high beam spot through each corresponding light-transmitting and refractive part 31 for external illumination. Through multiple light-transmitting and refractive parts 31, each light emitting part 21 projects high beam spots of different distances for illumination and some high beam spots overlap, ensuring the requirements of the high beam spot illumination center brightness and illumination range. The contradiction between the high beam spot center brightness and range illumination is solved, and the requirements of the application market for high beam spots are met.

[0031] like Figure 2 As shown, the limiting structure 6 of this embodiment includes a limiting groove 61 , and a clearance opening 62 is provided at the edge of the limiting groove 61 , so that the LED light source 2 can be easily fixed to the limiting groove 61 through the clearance opening 62 .

[0032] A limiting post 63 is disposed inside the limiting groove 61 , and the LED light source 2 is provided with a limiting bayonet 22 that cooperates with the limiting post 63 . The LED light source 2 is fixed to the limiting groove 61 through the cooperation between the limiting bayonet 22 and the limiting post 63 .

[0033] The lens fixing frame 4 of the present embodiment is provided with a fixing groove 41 , and the lens integrated lens 3 is provided with a limiting portion 32 which is clamped in the fixing groove 41 , so that the lens integrated lens 3 is fixed to the lens fixing frame 4 .

[0034] The lens fixing frame 4 is provided with an extension portion 42 which is locked in the clearance opening 62 , so that the lens fixing frame 4 and the fixing platform 5 are more tightly connected.

[0035] like Figure 3 As shown, in this embodiment, a limiting protrusion 43 is provided in the fixing groove 41 , and the limiting portion 32 is provided with a limiting hole 33 matching the limiting protrusion 43 , so that the lens integrated lens 3 is limited in the fixing groove 41 .

[0036] like Figure 4 As shown, the radiator 1 of this embodiment is provided with a heat dissipation cavity 11, and a plurality of heat dissipation fins 12 are arranged around the heat dissipation cavity 11. A heat dissipation fan 13 is arranged in the heat dissipation cavity 11. The heat dissipation fan 13 is used to cool the plurality of heat dissipation fins 12, so that the temperature of the radiator 1 is reduced, thereby controlling the temperature of the LED light source 2.

[0037] The heat sink 1 of this embodiment is provided with a heat collection cavity 14 connected with the heat dissipation cavity 11 on one side close to the LED light source 2. The heat collection cavity 14 reduces the thickness of the heat sink 1, so that the LED light source 2 can be collected in the heat collection cavity 14. A hollow groove 15 is provided between two adjacent heat sinks 12, and the air driven by the heat dissipation fan 13 passes through the hollow groove 15, thereby increasing the contact area between the heat sink 12 and the cold air, and making the cooling effect of the heat sink 1 better.

[0038] The fixed platform 5 of this embodiment is provided with a wiring hole 51 running through it. The LED light source 2 is provided with a wire passing hole 23, and the heat collecting cavity 14 is provided with a wire trough 141.

[0040] One end of the fan guard net 16 is provided with a protective cover 161. A clamping groove 121 is provided on one side of the heat sink fin 12 corresponding to the wire trough 141. The protective cover 161 is clamped in the clamping groove 121 and covers the wire trough 141 to prevent the heat generated by the operation of the LED light source 2 from being conducted to the heat collecting cavity 14 through the wire passing hole 23, the wiring hole 51, and the wire trough 141.

[0041] As Figure 5 shown, the light-transmitting refraction part 31 of this embodiment includes a first refraction part 311 and a second refraction part 312. The first refraction part 311 is arranged above the second refraction part 312. The high beam light spot is divided into upper and lower parts by the first refraction part 311 and the second refraction part 312, increasing the irradiation range of the high beam light spot.

[0042] The first refraction part 311 of this embodiment includes an upper half lens 3111 and a lower half lens 3112. The upper half lens 3111 is arranged on the top of the lower half lens 3112, further subdividing the first refraction part 311 into upper and lower layers and increasing the irradiation range of the high beam light spot.

[0043] The second refraction part 312 includes a first lens 3121, a second lens 3122, a third lens 3123, and a fourth lens 3124. The first lens 3121, the second lens 3122, the third lens 3123, and the fourth lens 3124 are arranged in a "field" shape. The high beam light spots are partially overlapped by the first lens 3121, the second lens 3122, the third lens 3123, and the fourth lens 3124, increasing the central brightness of the high beam light spot.

[0044] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, based on the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present invention.
