基于粉浆法提高功率型白光LEDs的提取效率
Investigation on Improving the Extraction Efficiency of Power White LEDs with Slurry Method
摘要
Abstract
Slurry method based on a phosphor suspension in a water-soluble photoresist was discussed.A conformal-coating phosphor layer was deposited on the surface of LEDs.The luminous performance of power white LEDs was found to be mainly depending on the concentration and ratio of ingredients in slurry and the structure of coating layer.In this paper,the parameters were investigated and some advices,which were suggested to improve the performance,were proven to be effective in our experiment.The aging testing of LEDs with this slurry method showed that the luminous flux was 95.95% of that of the beginning after the LED was lightened for 168 h at 700 mA.关键词
