Abstract :
This paper systematically analyzes first the effect of phosphor geometry on luminous flux of phosphor-converted LED. Five phosphor geometries are investigated based on Mie-theory calculations. Results show that phosphor geometry has impact on luminous flux, and pcLED with a phosphor layer of spherically top surface achieve an improvement of 12%.
