The new study found that: LED lamp with heat pipe cooling technology

It is reported that the British inventor James Dyson's son Jack Dyson recently released one of his research achievements: the use of heat pipe technology for cooling LED lighting, allowing them to achieve a more sustainable and stable lighting effect.

This technology is said to cost Jack Dyson and his team of engineers behind time ten years. The heat pipe cooling technology is mainly used in satellite processor and heat, no one wanted to use it in civilian lighting field. Using the technology of CSYS lamp with high power LED lamp 8 8mm interval, and can do a dense array of 8mm, so the final output is realized in the 648LUX space of 1 square meters in the illumination (about ordinary incandescent lamp several times) parameters, and has sustained high brightness output life 144000 hours.

It is understood that the basic principle of this technology is a vacuum lamp frame along the lateral sealing of the lighting lamp is arranged inside the tube set. Each tube in a drop of water seal seal. After the lamp is turned on, the heat generated by the LED to pipe water into steam, under the action of the pressure difference along the tube steam began to move. When the steam reaches the cooling region of the copper pipe, will again return to water condensation, heat dissipation. Then, the water is sucked back into the direction of LED, LED and cooling cycle starts again.

Although the LED luminous particles compared to traditional lighting is greatly reduced, but some high brightness models will still produce high temperature, long-term use can cause a significant impact on life. General LED lighting is more use of passive metal sink tradition, although not what meet the general brightness problem, but if you want to use high brightness and high brightness LED device if the cooling effect is not guaranteed.
