Problems solved by technology

The passive heat dissipation system takes the LS600h car lamp as an example. Although the energy consumption of the LEDs used is slightly less, a total of about 45W, due to the passive heat dissipation method, a large amount of aluminum alloy has to be used as a heat sink, which makes the weight of the whole light h

Example Embodiment

[0026] The invention discloses a vehicle lamp, such as figure 1 , 2 , 3, 4, including a lamp body 2, an elastomer pipe 8, a radiator 9 and a light source. The upper and lower side walls of the lamp body are both provided with opening structures for connecting the elastomer pipe, That is, the elastomer pipe penetrates the lamp body up and down through the opening structure and is fixedly connected with the lamp body, the two ends of the elastomer pipe are open and communicate with the atmosphere, and the radiator is installed on the On the wall of the elastomer pipe, the fins of the radiator extend into the elastomer pipe and directly contact the air flowing in the pipe, and other parts of the radiator are located outside the elastomer pipe and the The inner side of the lamp body is used as the basic structure for the fixed installation of the light source. The heat generated during the light-emitting process of the light source is first transferred to the fins through thermal c...

Abstract

The invention relates to a lamp for a vehicle. The lamp comprises a lamp body, an elastic body pipe, a radiator and a light source, the elastic body pipe vertically penetrates the lamp body and is fixedly connected with the lamp body, openings in the two ends of the elastic body pipe are communicated with atmosphere, the radiator is installed on the wall of the elastic body pipe, a fin part of the radiator extends into the elastic body pipe to be in direct contact with air, and the other parts of the radiator are located outside the elastic body pipe and the inner side of the lamp body; and the light source is located on the inner side of the lamp body and is installed on the radiator, LEDs are adopted as the light source and are directly installed on an LED substrate, the LED substrate is located on the inner side of the lamp body and fixed to the radiator. The lamp is high in radiating efficiency and low in power dissipation, and therefore full play is given to the energy conservation advantage of the LED light source, and meanwhile, the needs of flexible adjustment and dynamic lighting can be met.

Description

technical field [0001] The invention relates to a lamp for a vehicle, in particular to a lamp for a vehicle that can realize efficient heat dissipation of an LED light source. Background technique [0002] In recent years, LED has been widely concerned and praised by the market for its green and energy-saving advantages. However, after investigating the energy consumption of LED lamps on some models, it was found that LED lamps for vehicles are not more energy-efficient than lamps with traditional light sources. This is mainly because the photoelectric conversion efficiency of the LED is low, and it will generate heat while emitting light. About 65%-85% of the electric energy is converted into heat energy, which makes the heat dissipation problem of the LED prominent. If the heat dissipation design of the LED is improper, it will cause the LED If the temperature of the chip junction is too high, the life of the device will be shortened. When the heat accumulates to a certai...
