Description

A kind of LED car light

technical field

The utility model belongs to the technical field of lighting, and relates to a vehicle lamp, in particular to an LED vehicle lamp.

Background technique

At present, high-power halogen lamps are generally used for vehicle lights. The disadvantages of halogen lamps are: short service life, high bulb power, resulting in large power consumption and low available efficacy. Later, LEDs were used to replace halogen lamps. The advantages of LED lamps are: long service life, high brightness, wide illumination area, low power, low power consumption, high efficiency, and raw materials can be recycled and reused. However, the heat dissipation effect of the existing LED car lights is not good, it is difficult to increase the power of the LED car lights, and the application occasions are limited.

Contents of the invention

The utility model provides an LED vehicle lamp with good heat dissipation effect, simple, compact and reasonable structure.

The utility model realizes its purpose through the following technical solutions:

A lamp cup for a car lamp and an LED light source. A glass lens is installed on the lamp cup for the car lamp. A heat pipe is also installed at the place, and the LED light source is connected with the heat pipe. The heat pipe passes out of the light cup along the center position of the light cup backward. Laminated fins are installed on the heat pipe, and there is liquid vapor in the heat pipe.

A radiator is also fixed at the center of the lamp cup of the car lamp, and the heat pipe is installed at the center of the radiator.

The heat-conducting tube is a heat-conducting copper tube, and the laminated heat sinks are all circular heat-dissipating fins installed at both ends of the heat-conducting copper tube and located outside the rear and outer sides of the lamp cup. The LED light source is located in the middle of the heat-conducting copper tube.

The beneficial effects of the utility model are:

The LED light source of the utility model is installed on the heat-conducting pipe, and there is liquid steam in the heat-conducting pipe, so that the heat conducts heat quickly through the heat-conducting pipe and the liquid vapor in the heat-conducting pipe, and a heat sink is installed at the rear end of the heat-conducting pipe, so that the heat dissipation effect is better, the structure is simple, Compact and reasonable.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figures 1-4, the utility model LED car light includes a car light cup 1 and an LED light source 3. A glass lens 2 is installed on the car light cup 1, and the LED light source 3 is installed on the car light cup through a substrate 4. 1, a heat pipe 5 is also installed at the center of the lamp cup 1 of the car lamp. It is connected with the heat conduction pipe 5 and located above and below the heat conduction pipe 5. There is liquid steam 8 in the heat conduction pipe 5, and the LED light source conducts heat rapidly through the heat conduction pipe and the liquid vapor in the heat conduction pipe. A radiator 6 is also fixed at the center of the lamp cup 1 of the car lamp. The radiator 6 is a heat sink, and the heat pipe 5 is installed at the center of the radiator 6 . Wherein the heat pipe 5 is a heat conduction copper pipe, and the laminated heat sinks 7 are circular heat sinks installed on both ends of the heat conduction copper pipe and located at the rear and outer side of the lamp cup 1 of the car lamp, and the LED light source 3 is located in the middle of the heat conduction copper pipe place.
