蓝光LED激发MPR-1003红色荧光粉器件性能研究
The research of the device characteristics on the MPR-1003 red fluorescent material excited by blue LED
摘要
Abstract
T he spectra and light efficiency are studied firstly ,w hen the M PR‐1003 fluorescent material is stimulated by the blue LED chip .It shows that the spectrum contains blue and red components after coated fluorescent material .With the addition of phosphor fraction ,the in‐tensity of blue light decreases ,w hereas the red light increases .When the ratio of the mass of the red fluorescent material to that of glue equals to 4∶6 ,blue light peak disappear com‐pletely ,and there is only one peak at red light band .At this time ,the LED device appears pure red ,the color purity reaches 99 .7% .When the fluorescent material mass fraction increa‐ses ,the light efficiency is on the decline .And analyze the reason of change of the spectra and light efficiency .Finally ,the brightness of the device ,the chip temperature and voltage as the function of time was tested ,and analyse the relationship between the threes .关键词
