Cree puts most light into smallest lighting LED
Cree has stretched the output of its 1.6×1.6mm XQ LED package.
Called XQ-E, the device gets the 1mm die from its XP-E2 LED, and a domed XQ package with a 110° output.
“Optically it is actually the same as XP-E2,” Cree marketing manager Paul Scheidt told Electronics Weekly. “It is a much smaller building block to mix for colour-change because it has much better lumen density. We are going to make white and RGB all available at the same time.”
Peak planned white output is 287 lm at 3W, 85°C.

Thermal resistance is down, to 7°C/W from 9°C/W of the XP-E, said Scheidt.
Applications are expected in portable, indoor directional, architectural and vehicle lighting.
