this small size with such a high level of performance,” says Luke Thorkildsen, director of lighting division, The Coleman Company, Inc. “We’re excited about the new possibilities for smaller, lighter or brighter designs enabled by the new XQ-E LED.”
The new XQ-E LEDs have a tiny 1.6 mm x 1.6 mm footprint and are available in both white and colour configurations. The XQ-E’s combination of optical symmetry, consistent design across all configurations and its small size enables improved colour mixing and optical control compared to the larger XP-E2 LED.
“Previously, the size of LEDs dictated the form factor of the luminaire and lighting manufacturers had to design around the light source,” explains Paul Thieken, director of LED Components, Cree. “With its unparalleled performance and size, the XQ-E LED redefines what’s possible with lighting designs, enabling new form factors and eliminating constraints.”
Built on Cree’s revolutionary SC3 Technology Platform and characterised at 85°C, the XQ-E White LED is available in 2700-K to 6200-K colour temperatures and offers minimum CRI options of 70 and 80. The XQ-E White LED delivers up to 287 lumens at 3 W, 85°C. XQ-E Colour LEDs are available in red, green and blue.
Cree XLamp XQ-E White LED samples are available now, and colour LED samples will be available in late October. Production quantities are available with standard lead times.
Nitride Solutions ships first AT-50 AlN templates
The aluminium nitride templates, produced using HVPE, have been sold to a major Asian LED manufacturer
template properties far superior to any presented before. This data accelerated requests for sampling by major manufacturers of LEDs and power-switching devices.
“Our templates are by far the best in the market, and our manufacturing processes are designed for volume production and tight statistical process control. We offer customers the best commercially available XRD specs (average (002): 135 arc sec and (102): 513 arc sec), low defect densities, and wafer uniformity,” says Jeremy Jones, Nitride Solutions CEO.
He continues, “We believe that our recent sales and growing sample requests validate the quality and value of our products and technology. We realise that customer’s make decisions on substrates based on performance, quality, consistency, value delivered and supply assurance. Our combination of a superior product in the AT-50 plus a growing global distribution and technical support channel will provide the best solution for these customers. The planned introduction of four- inch aluminium nitride templates and the expansion of our template product line to GaN will bring additional value to device markets.”
James H. Edgar, department head of chemical engineering and university distinguished professor at Kansas State University comments, “The AlN on sapphire templates offered by Nitride Solutions are a much lower-cost alternative of high-quality material compared to bulk AlN substrates. That these substrates are available in two-inch diameter size greatly facilitates their use by standard device fabrication tools. The availability of these AlN templates creates exciting new opportunities for improved short-wavelength optoelectronic and high-power electronic devices.”
Nitride Solutions develops and manufactures bulk and template nitride materials for the LED, laser diode and the power electronics markets. Founded in 2009, the firm’s leadership has over 35 years of experience in supplying advanced materials to global manufacturers of semiconductor, display and memory devices, combined with a total of more than 35 years in nitride process development. The company maintains strong ties to Kansas State University in Manhattan, with key employees and advisors hailing from the university, as well as UC Santa Barbara.
Nitride Solutions has achieved the first commercial sales of its new AT-50 AlN template.
Nitride is manufacturing the product in volume at its manufacturing facility in Wichita, Kansas, using its proprietary advanced HVPE process.
