Lamp used for vehicle

Abstract

The invention relates to a lamp for vehicles, comprising a radiator, a lamp body, a flexible heat pipe located inside the lamp body, an AFS rotating shaft, an LED installation base and LEDs, and the radiator is installed on the rear side of the lamp body on the wall, and the fin part of the radiator protrudes out of the lamp body to directly contact with the outside air, the other part of the radiator is located inside the lamp body, and the AFS rotation axis is vertically The shaft is rotatably connected to the lamp body, the LED installation base is fixed on the top of the AFS rotation shaft, the LED is installed on the LED installation base, and one end of the flexible heat pipe is connected to the LED installation base. The seat is fixedly connected, and the other end is fixedly connected with the other parts of the heat sink. The invention has high heat dissipation efficiency and low power consumption, so that the energy-saving advantages of the LED light source can be truly brought into play, and at the same time, 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...

AI Technical Summary

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 heavier than that of active heat dissipation. The heavier ones are generally greater than 5Kg

It can be seen that the auxiliary system required for vehicle LED lamps due to heat dissipation significantly increases the energy consumption of the whole lamp, so that the energy originally saved by LEDs is basically offset. Therefore, these seemingly energy-saving products do not really reduce carbon emissions.
