英文摘要	Under different drive current and heat sink temperature, luminous performances as well as physical mechanisms were studied for both traditional phosphor-dispensing packaging white LED and blue light-converting hemisphere remote phosphor LEDs. With the increase of the heat sink temperature and the drive currents, the quantum efficiency and light conversion efficiency in the traditional phosphor-dispensing packaging white LED drop rapidly, which is responsible for the decrease of Y/B ratio (Yellow/Blue Ratio) and the apparent increase of CCT (correlated color temperature). However, the parameters of quantum efficiency, light conversion efficiency and CCT in blue light-converting hemisphere remote-phosphor packaging LEDs have little change under the same experimental conditions. In addition, the remote phosphor LEDs exhibit a batwing spatial luminous intensity distribution and the spatial Y/B ratio distribution is much more homogeneous compared with the traditional phosphor-dispensing packaging white LED.
