Abstract

The invention discloses a thermal-drive natural-circulation lamp pole cooling system for an LED streetlamp, which comprises an LED streetlamp body, a vertical lamp pole, a steam tube and a return tube. The steam tube and the return tube are communicated with the upper end and the lower end of the lamp pole respectively. The other end of the return tube and the other end of the steam tube are respectively communicated with the LED streetlamp body. A partition is disposed inside the LED streetlamp body. An evaporation chamber is reserved below the partition and filled with liquid medium. An LED chip substrate is disposed at the bottom of the evaporation chamber, an LED chip is disposed at the bottom end of the LED chip substrate, and the return tube is communicated with the evaporation chamber. The steam tube is connected to the upper end of the LED streetlamp body. A drain tube is further connected above the partition inside the LED streetlamp body. The other end of the drain tube is communicated with the lower end of the lamp pole. The thermal-drive natural-circulation lamp pole cooling system for the LED streetlamp is reasonable and compact in structure, high in heat conducting efficiency, fast in cooling speed and capable of effectively cooling an LED module, the cooling problem of high-power LEDs is solved, the speed of light attenuation is decreased, and the service life of the LED lamps is prolonged.

Description

technical field [0001] The invention relates to the field of heat dissipation systems for lighting equipment, in particular to heat-driven natural circulation light pole heat dissipation systems for high-power LED street lamps. Background technique [0002] In today's society that pays more and more attention to energy saving and emission reduction, LED lamps are being used more and more in lighting because of their advantages of high efficiency, low consumption, energy saving, environmental protection, and long life. However, the photoelectric conversion efficiency of ordinary high-power LED lamps is about 15%-20%, and about 80% of the electric energy is converted into heat energy. The mechanism of LED light emission is to generate light by the transition of electrons between energy bands, and its spectrum does not include the infrared part, so its heat cannot be dissipated by radiation. If there is no good heat dissipation system, working for a long time will cause the ju...
