| Abstract: | Luminous efficiency of high power white LED is studied from three perspectives including package, driving and heat radiation. By adopting technologies such as remote phosphor for white LED, pulse driving and single chip integrated semiconductor refrigeration, the luminous efficiency of high power white LED can be effectively improved. Theoretical analysis is made on 1W white LED, and it is pointed out that luminous efficiency can be increased by 15% or so with remote phosphor, 20% or so with pulse driving, 30% or so with single chip integrated semiconductor refrigeration, 79% or so with them all. |
