by AF 0823 a3 — August 26, 2009—Philips Lumileds continues to advance its core LED technology with its new LUXEON Rebel LEDs, says the company.
LEDs in a luminaire are operated at very high junction temperatures, often between 80C and 110C. As temperature increases, light output and efficacy decrease, notes the company. With a Hot / Cold Factor of 0.93, LUXEON Rebel LEDs deliver more light and better efficacy than virtually any other power LED, says the company. Maximizing this factor is critical as companies design solid-state lighting solutions to meet ENERGY STAR requirements.
“Hot / Cold Factor is one of the clear differentiators between LEDs,” said Rudi Hechfellner, Director of Technical Solutions. “A high HC Factor can simplify the thermal system design and lower the cost per lumen in the final application.”
Hot / Cold Factor charts for all LUXEON Rebel LEDs are available on the company’s Web site.
