| 摘 要： | 采用GaN基蓝色发光芯片为激发源,结合黄色硅酸盐系列荧光粉封装成大功率白光发光二极管(W-LEDs).利用24颗大功率5W白光发光二极管制作了两种不同连接方式的W-LEDs路灯:2并12串,和4并6串.设计了相应的驱动电路,对这两种不同连接方式的大功率W-LEDs路灯的光电特性及其在照明光源中的应用条件作了深入地研究和对比,测试了它们的伏安特性,发光效率以及功效,结果表明2并12串连接方式的W-LEDs路灯具有更加稳定的伏安特性,更高的照度以及更高的功效.与高压钠灯和荧光灯的特性相比较,W-LEDs路灯作为绿色环保光源灯,具有更高的显色指数,更加环保,节能.

| Abstract: | With GaN blue light emitting diodes(LEDs),high-power white LEDs(W-LEDs) were packaged with yellow poly-silicate phosphor.In this paper,W-LEDs lamps were made by 24 pieces high-power W-LEDs in two different connection ways: 2-parallel with 12-series,and 6-parallel with 4-series.With a proper driving circuit for the high-power W-LEDs lamps,the I-V characteristics,current illumination characteristic,power,and efficiency of the two different connections were studied,the experiment result showed that 2-parallel ... |
