LEDs intensify lumen density

24th March 2015

The first LEDs powered by Cree’s SC5 Technology Platform, XLamp XHP50 and XHP70 LEDs provide twice the lumen output and improved reliability compared to previous LEDs of the same size and are on sale at MSC Technologies. XHP50 and XHP70 LEDs shatter the industry’s perceived limit of LED lumen density by delivering up to 2546lm at 19W from a 5mm2 package and up to 4022lm at 32W from a 7mm2 package, respectively.

Through improvements in the light conversion process, Cree has reduced LED-to-LED colour variations and, among other options, offers XHP LEDs in 2-step and 3-step EasyWhite bins for 3500K through 2700K in 80 and 90 CRI.

The XHP LEDs introduce an innovative package that allows manufacturers to choose either 6 or 12V configurations from the same LED through the solder pad design on the circuit board.

The LEDs enable other cost reductions at the system level. For example, in roadway and outdoor area lighting, on top of the luminaire cost savings, they can produce a radically smaller and lighter luminaire that requires a less expensive pole.

Similar cost savings over existing solutions may be achieved in a wide variety of lighting applications, including track, stadium and high bay.
