High power LED lighting lamp and radiating module thereof

Abstract

The invention discloses a high power luminescent diode lamp and heat dissipation module thereof, which includes a LED heat transmission base, at least one LED array, at least one heat pipe and a heat dissipation module. The LED head transmission base has at least one LED collocation surface and at least one heat pipe trepanning. The LED array includes a plurality of LEDs, and each of the LEDs is arranged on the LED collocation surface at a preset angle. The heat pipe has a heated section, a condensation section and a transmission section, working fluid is contained in the heat pipe, and the heated section is nested in the heat pipe trepanning. The heat dissipation module is equipped in the condensation section of the heat pipe. Heat energy generated by the LED is transmitted to the heated section of the heat pipe by the LED heat transmission base, the working fluid of the heat pipe is heated to vaporize and flows to the condensation section through a transmission region, the heat dissipation module absorbs the energy carried by vaporized working fluid and dissipates the energy.

Description

technical field [0001] The invention relates to a light-emitting diode lighting fixture, in particular to a high-power light-emitting diode lighting fixture and its heat dissipation module, which can replace incandescent light bulbs and fluorescent light sources. Background technique [0002] In the Kyoto Conference held in 1997 to prevent global warming, Japan was required to reduce its greenhouse gas emissions by 6% from 2008 to 2012 compared with the 1990s, so it accounts for more than 20% of the energy used for people's livelihood. Lighting electricity , the development of its energy-saving lighting technology is extremely important. The light-emitting diode (LED) is a photoelectric semiconductor element that emits light by exciting electrons with an external voltage. Because of its advantages of low power consumption and long life, all countries are actively developing related technologies. At present, most of them are only used in practical applications. In the range ...

AI Technical Summary

Problems solved by technology

Because the luminous point area of ​​high-power LEDs will form hot spots (Hot Spots), and the current luminous efficiency technology of high-power LEDs cannot be rapidly improved. The biggest bottleneck is the inability to effectively "radiate heat" and when bonding When the temperature of the point exceeds 120°C, the performance of the LED will be attenuated, the life will be shortened, and there will be a danger of burning
