Abstract

InGaN LED efficiency depends significantly on current density, emission wavelength and junction temperature. Phosphor-converted blue LEDs are still more efficient than RGB multi-LED solutions despite inevitable Stokes losses: 104 lm/W at 350 mA have been demonstrated for a warm-white (TC = 2950 K) phosphor-converted blue InGaN LED with 1 mm2 chip size.
