It is reported that the British inventor James Dyson's son Jack Dyson has announced a research and development result: the use of heat pipe technology to cool LED lighting, so that they achieve a more continuous and stable lighting effect.
The technology is said to have cost Jack Dyson and the team of engineers behind him for ten years. Previously, heat pipe cooling technology was mainly used in satellite and processor heat dissipation, and no one ever thought about using it in the field of civil lighting. The CSYS desk lamp with this technology has built in 8 high-power LED lamp beads with 8mm spacing, and can achieve 8mm dense arrangement, so the illuminance of 648LUX is output in 1 square meter space (about ordinary white woven lamp). Several times the parameters, and has a continuous high brightness output life of 144,000 hours.
It is understood that the basic principle of this technology is to set a vacuum sealed copper tube in the lighting lamp along the horizontal lamp holder. Seal a drop of water in each sealed copper tube. After turning on the light, the heat generated by the LED causes the water in the tube to become steam, and under the pressure difference, the steam begins to move along the tube. Once the steam reaches the cooling zone of the copper tube, it will recondense and return to the water, so that the heat energy is dissipated. Then, the water is sucked back into the LED direction, and the cooling cycle of the LED then starts again.
Although LED illuminating particles are greatly reduced compared to conventional lighting fixtures, some high-brightness models still produce higher operating temperatures, which have a significant impact on longevity. In general, LED lighting fixtures use more traditional passive metal heat sinks. Although there is no problem in dealing with general brightness, if you want to use high-brightness and ultra-high brightness LED devices, the heat dissipation effect is not guaranteed.
