Cree, Inc. continues to lead high-power LED innovation with significant improvements to the popular XLamp® XT-E LED. Leveraging key elements of Cree’s SC5 Technology™ Platform, the upgraded XT-E LED family now includes a new High Efficacy (HE) option that delivers a 25 percent increase in efficacy compared to the previous XT-E LED and provides a guaranteed minimum efficacy of 164 LPW at 85°C and 350mA. These improvements make 130 LPW or higher at the system level achievable under real operating conditions and enable existing customers to quickly upgrade system performance of applications, such as outdoor and industrial lighting, while still achieving the lowest total cost.
“We are committed to building the most energy-efficient industrial lighting systems and the newly improved High Efficacy XT-E LED enables us to do that without any additional investment or requalification,” said Colin Piepgras, vice president of engineering at Digital Lumens. “With the new XT-E LED, we are able to leverage existing optical, mechanical and electrical design elements to quickly improve our portfolio of intelligent lighting solutions.”
The enhanced XT-E LED improves the brightness, voltage characteristics and optical performance in the same, proven 3.45mm x 3.45 mm XT package. Demonstrating the excellent long-term reliability of Cree’s high-power ceramic LEDs, the XT-E LEDs now have more than 10,000 hours of LM-80 data available, delivering reported L90 lifetimes of greater than 60,000 hrs, at 105°C, 1A. This industry-leading reliability is ideal for applications like outdoor and high bay lighting where long lifetimes at high ambient temperatures matter. For example, XT-E’s improved efficacy and reliability make it well-suited for the recently updated DLC 4.0 requirements.
“Our customers rely on Cree for innovations that allow them to upgrade their existing products to both gain a competitive edge and meet increasing industry requirements,” said Dave Emerson, vice president and general manager for Cree LEDs. “Cree’s improved XT-E LED provides an immediate solution that eliminates the time and cost of redesign around other unproven alternatives.”
