发光二极管照明供电方式的研究

近年来高光效、高亮度的白光LED的开发成功,使得LED在照明领域的应用成为可能。LED将发展成第四代光源,即半导体照明。进入半导体照明时代一方面要加强LED的机理工艺的研究,提高LED的效率,降低成本,另一方面由于LED的伏安特性,光电特性的复杂性、非线性对发光二极管照明系统的供电方式也应进一步地进行研究,才能够达到能的合理利用,使整个照明系统的效率达到最高,前者研究的人较多而后者目前还很少有人研究,本文针对LED照明的供电问题进行了研究对提高LED的供电效率及稳定性提出了相应的解决方法。

Research of the LED lighting power supply method

Because of the successful development of the white light LED of the high light effect and high brightness in recent years,the application of the LED at lighting realm makes possible.The LED will become the fourth generation light source,namely the semi-conductor lighting.For achieving the semi-conductor lighting,one hand is to strengthen the research for the mechanism craft of the LED,raise efficiency of the LED and decline cost,on the other hand because the LED has volt-ampere characteristic,the complexity of the photoelectricity characteristic and non-linearity characteristic,we should research the power supply method of the LED lighting system further to achieve the reasonable using of power and it can make the efficiency of the whole lighting system highest.There are too many people to research the former but what we do the latter so few currently.This text carries on the research to the power supply problem of the lighting of LED,and put forward a method towards raise the power supply efficiency and stability of the LED.
