| 摘 要： | 研究了利用荧光颜料和InGaN蓝光芯片制成掺杂LED，根据光转换原理，得到白光LED的可能。文章首先对比了普通方法和二次点胶法封装的LED，表明二次点胶法工艺复杂，封装的LED亮度低，不适合LED的制造。其次对普通方法封装的1/1/100，1/1/200，2/1.5/100等不同重量比的ax-17/zq-13/AB胶有机LED实验，发现2/1.5/100的有机LED色坐标(0.32, 0.30)，接近等能白光点，相关色温6 290 K，接近日光，是一种比较理想的白光源。

| Abstract: | Some hybrid organic LEDs are made by using fluorescence dye and InGaN blue-light chip and the possibility of achieving white organic LED is invesgated according to light conversion theory. Firstly, the LEDs made by normal method and double-dotting glue method are studied. It is found that the double-dotting glue method is too complex and the LEDs made by this way is (low-luminance), so it isn't fit to make LED. Secondly the different weight ratio of 1/1/100, 1/1/200, 2/1.5/100 ax-17/zq-13/AB LEDs are manufactured. The 2/1.5/100 LED's color coordinate is(0.32, 0.30), approaching to white point and the correlative color temperature is 6290K which is close to sunlight. So it is a relatively ideal white lamp-house. |
