the LEDs at a constant current

Last summer, the scientists field-tested 196 prototypes with the help of children who attended a Danish-run summer school in Zambia. The results showed that some of the lamps had problems due to excessive flexing and light quality degrading after 10 to 20 minutes, which the scientists are fixing by repositioning the solar cells and adding circuitry to deliver power to the LEDs at a constant current. The researchers plan to test improved versions of the lamps in Mali and Malawi.

This investment enables us to expand our presence in China and demonstrates our commitment to serving the growing demands of both our local and global LED customers,” said Chuck Swoboda, Cree chairman and CEO. “We are building on a solid foundation in Huizhou with a strong local management team and a history of manufacturing excellence. We look forward to continued success in China as we drive the led high bay light revolution.”

More than half of Cree’s employees work in China, mostly at the current Huizhou factory. Cree recognizes the support of Party Secretary YeBin Huang and Mayor RuQiu Li during the site selection process.
