Lighting-Class LED

DURHAM, N.C., Oct. 9, 2009 – Cree Inc. has announced the commercial availability of the XLamp XP-G cool white LED, a bright and efficient lighting-class LED. It produces up to 367 lm when driven at 1A, at a typical efficacy of 111 lm/W, making it 46% brighter and 64% more efficient than the proprietary XR-E LED, with an 80% smaller footprint, according to the company.

This level of performance can reduce the required number of LEDs as well as the size and cost of LED fixtures. High efficacy at a reduced current (up to 132 lm/W, typical, at 350 mA) can lower the total power requirement for a portable or solar lighting application, which can reduce the number of solar cells or batteries needed.

The LED is available now with order codes up to 139 lm, minimum, at 350 mA and ANSI-compliant chromaticity bins (5000 to 8300 K correlated color temperature).

Maximum drive current is 1000 mA, thermal resistance is 6 °C/W, and viewing angle is 125°. Temperature coefficient of voltage is -2.1 mV/°C, reverse voltage is 5 V, typical forward voltage at 350 mA is 3 V, with 3.75 V maximum. At 700 mA, typical forward voltage is 3.2 V and, at 1000 mA, 3.3 V. LED junction temperature is 150 °C. Typical color rendering index is 75.

The RoHS- and REACH-compliant single-die device has an electrically neutral thermal path, an unlimited floor life and a symmetrical package. Applications include flashlights, head-mounted lighting, bicycle lighting and solar-powered lighting.
