today’s lighting systems, improving color quality, thermal stability and lifetime reliability.
Intematix applied its proprietary accelerated materials discovery and development process, C-MAT Synthesis, to develop the green aluminate and red nitride phosphors. By testing millions of combinations at once, Intematix develops ideal materials for LED performance with optimized particle morphology and high quantum efficiency.
Intematix provides customizable, patented phosphors that serve as the foundation for high- quality, energy-efficient LED light. The firm’s products enable attractive, vivid color quality, superior consistency, uniformity and stability. Headquartered in Fremont, California, Intematix maintains R&D, manufacturing, business and support operations in the U.S., Asia and Europe.
Cree’s New Lighting-Class LEDs Shatter Industry Standards
The commercially available single-die XLamp XM-L LEDs deliver 1000 lumens, at 100 lumens per watt.
Cree, a market leader in LED lighting, announces the commercial availability of the industry’s brightest, highest performance lighting-class LEDs.
With breakthrough light output and efficacy, Cree XLamp XM-L LEDs are designed for very high- lumen applications, such as high-bay or roadway lighting.
The XLamp XM-L LED has gone from concept to commercial availability in less than eight months, demonstrating Cree’s proven commitment to developing the highest performance, most cost-effective LEDs optimized for each lighting application.
“The XLamp XM-L LED can fundamentally change the way Cree customers look at LED light,” said John Edmond, Cree director of advanced optoelectronics. “An LED with this level of light output and this level of efficacy can accelerate the development of high-output commercial lighting products and could enable applications we haven’t even thought of yet. This sets a new standard for LED performance.”
Cool white (6500 K) XLamp XM-L LEDs deliver 1000 lumens with 100 lumens per watt efficacy at 3A. In a compact 5 mm x 5 mm footprint, XM-L LEDs offer the unique combination of very high efficacy at very high drive currents delivering light output and efficacy of 160 lumens per watt at 350 mA and up to 315 lumens and 150 lumens per watt at 700 mA, providing a 20 percent efficiency gain from Cree’s current industry-leading XLamp XP-G LEDs.
XLamp XM-L LEDs are available in sample and production quantities with standard lead times.
Cree is a market-leading innovator of lighting-class LEDs, LED lighting, and semiconductor solutions for wireless and power applications.
The firm’s product families include LED fixtures and bulbs, blue and green LED chips, high-brightness LEDs, lighting-class power LEDs, power-switching devices and radio-frequency/wireless devices. Cree solutions are driving improvements in applications such as general illumination, backlighting, electronic signs and signals, variable-speed motors, and wireless communications.
