| Abstract: | Various cooling systems and methods applied to high power LED lamps are introduced.According to the characteristics of high power LED lamps,a series of heat pipes with specific fin structures are developed and tested under different conditions.Test results show that the new heat pipe heat exchangers feature higher efficiency of heat dissipation and more compact construction than the conventional heat pipe heat exchangers and that the new heat exchanger with outwards-radiate fins has the best heat dissipation performance.The research findings can provide reference for the development of LED lamp cooling technology. |
