[0003] However, LED lamps generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the junction temperature of the LED chip will increase, affecting its luminous efficiency and lifespan, and even causing safety hazards. Therefore, how to improve the heat dissipation performance of LED lamps is a key technical problem that needs to be solved in the field of automotive lighting. Existing LED lamp heat dissipation methods mostly use a simple heat sink combined with a fan structure, which has limited heat dissipation efficiency and is difficult to meet the needs of long-term stable operation of high-power LED lamps. At the same time, the process of replacing the lamp body after damage is cumbersome. Therefore, it is necessary to design a dual-light lens direct-emitting LED lamp with an efficient heat dissipation design that is easy to install to solve the above problems.

The interior of the guide tube 92 is horn-shaped. A second mounting ring 93 is installed on the outer wall of the guide tube 92. Second heat sinks 94 are arranged at intervals on the second mounting ring 93. The second heat sinks 94 are arc-shaped on one side close to the conical tube 95, which can increase the contact surface between the airflow and the second heat sink 94. The left side of the second heat sink 94 is connected to the lamp holder 10. The right side of the lamp holder 10 is provided with a conical tube 95. The conical tube 95 is located in the middle of the second heat sink 94. The lamp holder 10 is provided with a lamp socket connector. The contact piece 11 is connected to the LED lamp core 2 through a circuit. The lamp body tube 1 is provided with a mounting assembly 12 for quickly docking with the vehicle body. The mounting assembly 12 includes a fixed seat 121, a rotating cylinder 122, a stopper 126 and a clamp 127. The fixed seat 121 is provided with a rotating cylinder 122. The inner side wall of the rotating cylinder 122 is symmetrically provided with a slide groove 123. The inner side wall of the rotating cylinder 122 is symmetrically provided with a clamping groove 124. The clamping groove 124 is connected with the end of the slide groove 123.The inner wall of the rotating cylinder 122 is circumferentially spaced apart with a limiting groove 125, and the outer wall of the lamp body tube 1 is circumferentially spaced apart with a limiting device 126, the limiting device 126 includes a limiting cylinder 1261, a first elastic member 1262 and a limiting column 1263, the outer wall of the lamp body tube 1 is circumferentially spaced apart with a limiting cylinder 1261, and a limiting column 1263 is slidably arranged in the limiting cylinder 1261, the limiting column 1263 cooperates with the limiting groove 125, and a limiting column 1263 is provided between the limiting column 1263 and the limiting cylinder 1261. A first elastic member 1262 is arranged, and the first elastic member 1262 is a compression spring. A clamping device 127 is symmetrically arranged on the right side of the lamp body tube 1. The clamping device 127 includes a second elastic member 1272 and a clamping column 1271. A circular groove is symmetrically opened on the right side of the lamp body tube 1. A second elastic member 1272 is arranged in the circular groove of the lamp body tube 1. The second elastic member 1272 is a compression spring. The second elastic member 1272 is connected to a clamping column 1271, and the clamping column 1271 cooperates with the clamping groove 124.

[0027] During installation, the staff first installs the fixing seat 121 on the vehicle body, and then inserts the connector 127 on the lamp body tube 1 into the slide groove 123 inserted into the rotating cylinder 122, and finally the clamping column 1271 is clamped into the clamping groove 124, and the limiting column 1263 is clamped into the limiting groove 125. Under the action of the first elastic member 1262 and the second elastic member 1272, the lamp body tube 1 and the rotating cylinder 122 can be protected to be firmly installed. The lamp contact piece 11 of the lamp holder 10 is connected to the head of the vehicle body. Since the installation position of the high beam and the low beam is fixed, when the direction of the LED wick 2 is reversed, the staff rotates the rotating cylinder 122 to adjust 180°, and the direction of the LED wick 2 can be adjusted, and then the line can be connected to the vehicle body. When the lamp is in operation, the cooling fan 7 starts to blow the wind directly toward the LED wick 2, thereby accelerating the air flow. The rotation of the cooling fan 7 can generate forced convection, so that the heat of the first heat sink 4 and the spiral heat sink 82 is dissipated into the air more quickly. At the same time, since the cooling fan 7 drives the turbofan 85 to rotate through the rotating shaft 83, the turbofan 85 generates suction, thereby driving the gas flow in the lamp body tube 1 more quickly, and accelerating the heat dissipation efficiency. When the airflow passes through the narrow part of the venturi tube 81, the static pressure will be significantly reduced due to the increase in flow rate. This pressure reduction can be used to measure the fluid velocity or provide external suction. Due to the sudden decrease in flow velocity and the diffusion of gas, a vacuum area or low pressure area will be formed. This area has an adsorption effect on the surrounding gas, which can induce the gas around the first heat sink 4 to enter the venturi tube 81, complete the flow of hot gas, and the gas can diffuse through the guide tube 92. Due to the existence of the tapered tube 95 and the arc-shaped end of the second heat sink 94, the flowing air is dispersed from the tapered tube 95 encountered, and the contact area with the second heat sink 94 can be increased during discharge, thereby improving the heat dissipation capacity of the device. In summary, the mounting structure of the vehicle lamp is not only easy to install and flexible to adjust, but also has a significant heat dissipation effect, which effectively improves the service life and performance of the vehicle lamp.
