AI Technical Summary

Problems solved by technology

Due to the limited thermal conductivity of metal aluminum, especially for high-power LED high bay lights, the fins near the luminous body are hotter and the other end is colder. The heat dissipation effect is not very ideal, which seriously affects the service life of LED high bay lights.

Abstract

The invention relates to an LED industrial and mining lamp, which includes an LED light source, a power supply and a heat dissipation unit connected with the LED light source; Quality; the heat transfer fluid working substance absorbs heat from the connection between the LED light source and the heat dissipation cylinder and evaporates into a gaseous state, then exchanges heat with the outside on the inner wall of the heat dissipation cylinder and re-forms into a liquid state, thereby forming a circulating cooling system. By using the heat transfer fluid working medium, the heat emitted by the LED light-emitting module is quickly transmitted to the entire radiator surface through the boiling, evaporation and condensation process of the heat transfer fluid, which effectively reduces the heat transfer temperature difference and greatly improves the heat transfer coefficient. The temperature of the whole radiator is uniform, and the heat dissipation effect is good.

Description

technical field [0001] The invention relates to an LED industrial and mining lamp, in particular to an LED industrial and mining lamp with a body heat pipe for heat dissipation. Background technique [0002] High-power LED is the most effective way to convert electrical energy into light energy. It has the advantages of low voltage, low energy consumption, long life, high reliability, easy maintenance, and fast response. It meets the requirements of energy saving and environmental protection for green lighting projects. It is considered It will surely become the fourth-generation lighting source, and the market prospect is very broad. However, LED is a cold light source, and the heat generated cannot be emitted by radiation. At present, the final luminous efficiency of the LED chip is only about 20%, and most of the electric energy is converted into heat. If it cannot be discharged in time, the temperature of the chip will rise. Various thermal effects due to temperature r...
