First extreme HPLEDs offer 40 percent system cost reductions

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.

“Cree’s new technology is game-changing compared to the incremental advances of other LED suppliers. The breakthrough performance of XHP LEDs enables both new design possibilities and dramatically lower system costs for LED lighting,” claimed Nate Heiking, Advanced Lighting product manager, Kenall Lighting.

XHP LEDs allow lighting manufacturers to reduce the size and cost of their lighting system design by using fewer, more reliable LEDs to achieve the same brightness. XHP LEDs enable new lighting designs that require fewer optics, a smaller printed circuit board, a smaller housing and less handling. XHP LEDs also achieve longer lifetimes even at higher operating temperatures and currents than previous LED technology, allowing lighting manufacturers to reduce heat sink size and cost without impacting the rated lifetime.

In addition, XHP LEDs enable other cost reductions at the system level not possible with other LED solutions. For example, in roadway and outdoor area lighting, on top of the luminaire cost savings, XHP LEDs can produce a 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.

“Cree’s new Extreme High Power LEDs demonstrate our belief that high-power LEDs are what will drive the industry towards the next generation of lighting system designs,” said Dave Emerson, vice president and general manager for Cree LEDs. “Leveraging our groundbreaking SC5 Technology Platform, Cree’s new XHP LEDs deliver not only exceptional performance, but also enable up to 40 percent system level cost reductions.”

As the first LEDs to incorporate the SC5 Technology Platform, the XHP LEDs introduce advancements in light output, color consistency and design flexibility. XLamp XHP50 and XHP70 LEDs shatter the industry’s perceived limit of LED lumen density by delivering up to 2546 lumens at 19 watts from a 5.0 x 5.0 mm package and up to 4022 lumens at 32 watts from a 7.0 x 7.0 mm package, respectively. Through improvements in the light conversion process, Cree has reduced LED-to-LED color 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 a new, innovative package that allows manufacturers to choose either 6 V or 12 V configurations from the same LED through the solder pad design on the circuit board.

Samples of both XLamp XHP50 and XHP70 are available now, and production quantities are available with standard lead times.
