Cree opens LED technical eval centers in China

June 13, 2012 – BUSINESS WIRE — Light-emitting diode (LED) company Cree Inc. (Nasdaq:CREE) is opening new technology centers in Shenzhen and Shanghai, China, expanding Cree TEMPO (Thermal, Electrical, Mechanical, Photometric, Optical) Services for LED lighting manufacturers evaluating LED luminaires.

The new technology centers will offer a range of TEMPO Services to meet the unique needs of lighting manufacturers in China, including the popular Cree TEMPO 21 and TEMPO Thermal Simulation Services. Cree’s experience indicates that many of the common quality issues and failure modes seen in Solid State Lighting products are not detected by currently available standardized tests. TEMPO 21 examines critical aspects of quality that commonly go unchecked such as chemical compatibility, driver spikes, dimmer compatibility and electrolytic capacitor analysis.

Tang Guoqing, senior advisor, Cree Hong Kong Limited, said “TEMPO Services can give manufacturers competitive advantages by helping them avoid costly design mistakes and by providing access to a broad range of test environments that are, in many cases, cost-prohibitive for them to build and operate.”

Effective LED luminaire thermal design is essential to ensure reliability and optimum performance. TEMPO Thermal Simulation predicts the thermal behavior of LED-based fixtures, including junction temperature, heatsink temperature, temperature profile and airflow profile. TEMPO SPOT gives customers access to complex, costly equipment to measure the photometric performance of luminaires and replacement lamps. Every TEMPO Service delivers an accurate, easy-to-understand TEMPO report that includes all testing results and relevant performance data.

In addition to the new China centers, Cree currently provides TEMPO Services out of its U.S. Cree Technology Centers located in Durham, NC and Santa Barbara, CA. For more information on Cree Services, please visit
