Problems solved by technology

However, the operating temperature of the LED has a direct and decisive effect on the luminous efficiency and service life of the LED, especially the high-power integrated LED lighting fixtures, which generate a large amount of heat and concentrate the heat, which makes the problem of heat dissipation more prominent. Transferred out, the resulting temperature accumulation will cause the LED junction temperature to be super high, which directly affects the light output efficiency and service life of the lighting fixture. The conventional heat dissipation method can no longer fully meet its heat dissipation requirements. The thermal control of high-power LED lighting fixtures has become Bottlenecks restricting its large-scale popularization and application

Abstract

The invention provides a phase transition radiator for a high power LED lighting lamp. The radiator comprises an evaporator (1), evaporation coils (2), fins (3) and fixed baffle plates (4). The radiator is characterized in that, the evaporation coils (2) are made by multi-pass rotary bending of a whole continuous pipe. The phase transition radiator for a high power LED lighting lamp of the invention has good reliability, strong radiation capacity, and high radiation efficiency. Moreover, the radiator has light weight, low cost and easy manufacture.

Description

technical field [0001] The invention relates to the field of thermodynamics, in particular to a phase-change radiator for high-power LED lighting fixtures. Background technique [0002] With the advancement of LED technology, it is a trend for LED lighting fixtures to develop towards high-power, integrated, and lightweight. However, the operating temperature of the LED has a direct and decisive effect on the luminous efficiency and service life of the LED, especially the high-power integrated LED lighting fixtures, which generate a large amount of heat and concentrate the heat, which makes the heat dissipation problem more prominent. Transferred out, the resulting temperature accumulation will make the temperature of the LED junction extremely high, directly affecting the light output efficiency and service life of the lighting fixture. The conventional heat dissipation method can no longer fully meet its heat dissipation requirements. The thermal control of high-power LED l...
