Abstract

This paper demonstrated that Y down / R up type is the preferable phosphor distribution for warm pc-WLEDs. Compared with common warm pc-WLEDs using silicone gel as the remote layer, a step-index remote configuration proposed herein exhibited a superior luminous efficacy at 67.4262 lm/W under 350 mA.
