PHILPS Lumileds breakthrough technology to improve the design of cold and heat coefficient simplified cooling system

LUXEON RebEL hot and cold coefficient to improve the efficiency of solid-state lighting, simplifying the design of heat dissipation

Through the improved chip and packaging technology, can be more convenient to meet the requirements of ENERGY STAR applications

Philips LumiLEDs continues to enhance its core LED technology, the latest breakthrough technology in the latest LUXEON Rebel LED can improve the efficiency of the lighting device operating temperature and light output performance. The coefficient of thermal output (i.e., the ratio of LED to 100 C LED junction temperature when the light output is at a temperature of 25 degrees C) is the standard value in the data sheet. The LED in the lighting device operates at very high junction temperature, typically between 80 C and 110 C. As the temperature rises, the light output and energy efficiency will be reduced. Just released LUXEON Rebel LED cold and hot coefficient of.93, can provide almost any other power LED high light output and efficiency. Junction temperature of 100 degrees C, the typical hot and cold coefficient range of.80 -.85. When designing a solid state lighting solution that meets the requirements of the ENERGY STAR, the company should be able to increase this factor as much as possible.

Rudi, director of technical solutions, said: "Hechfellner is one of the obvious differences between the various LED. High heat and cold coefficient helps to simplify the design of the cooling system, and can reduce the cost per lumen in the final application. "
