Abstract

This paper describes an experimental photometrical analysis regarding two mainstreams inside the high-brightness LED family: the power devices, so-called high power LEDs, and the low power devices. Focus is given to white phosphor-converted LEDs, which are used in LED-based luminaires for indoor and outdoor lighting. Data from several LEDs used in available luminaires are compiled and provided as photometrical references for the design considerations in light output of LED drivers which employ power electronic converters.
