Abstract :
This paper describes a methodology in predicting color of the LED packages in different phosphor geometry for package free LED. Through resolving the peaks attributed from the LED and phosphor, the Phosphor Spectral Portion-Vol. ratio relations was developed. From the relations, the spectrum for a LED with known phosphor geometry can be constructed. Color of the LED can then be deduced. The method serves the geometric design of the phosphor layer for package free LEDs.
