High-temperature self-starting heat dissipation device for LED lamp

Abstract

The invention discloses a high-temperature self-starting heat dissipation device for an LED lamp. The device comprises a lamp holder, a heat conduction plate is embedded in the lower end of the lamp holder; a heat dissipation cavity in zigzag distribution is formed in the side wall of the heat conduction plate; a lamp tube is installed at the lower end of the heat conduction plate, a hemisphericallampshade is fixedly arranged at the lower end of the lamp holder, the lamp tube is located in the lampshade, a sliding groove is formed in the lower end of the lamp holder, a heat conduction piece is embedded in an opening of the sliding groove, and a first power connection piece coupled with a circuit where the lamp tube is located is arranged at the top in the sliding groove. The first power connection piece, a second power connection piece, a memory alloy, a liquid pumping mechanism, an air outlet hole and the like are arranged; according to the LED lamp, the pulse current can be suppliedto a spring to drive the cooling liquid to circularly flow when an LED and the like are at abnormally high temperature, so that heat accumulated in the lampshade is taken away, the exchange speed ofair in the lampshade and outside air can be increased, the auxiliary heat dissipation effect is achieved, and the normal operation and the service life of the LED lamp body are effectively guaranteed.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a high-temperature self-starting cooling device for LED lamps. Background technique [0002] Due to its superior energy saving, environmental protection, high efficiency, safety, stable service life, high color rendering index and fast response, LED lights have replaced traditional incandescent lamps and become an indispensable and important part of urban lighting. The development and construction of urban civilization is of great significance. [0003] The essence of LED lights is light-emitting diodes. Therefore, when LED light sources are working, except for converting a small part of energy into light energy, most of the energy will be converted into heat energy. Therefore, the heat dissipation requirements of LED lights are generally high, and due to The packaging area of ​​the LED lamp is very small, and it is easy to generate heat accumulation in it. If the heat is not dissipated in t...

Problems solved by technology

[0003] The essence of LED lights is light-emitting diodes. Therefore, when LED light sources are working, except for converting a small part of energy into light energy, most of the energy will be converted into heat energy. Therefore, the heat dissipation requirements of LED lights are generally high, and due to The packaging area of ​​the LED lamp is very small, and it is easy to accumulate heat in it. If the heat is not dissipated in time, the temperature of the electronic components in the LED lamp body will rise abnormally, thereby affecting the service life of the LED lamp body. Therefore, it is necessary to propose a A device capable of cooling and dissipating heat from LED lamps at high temperatures
