“The XM-L2 LED efficiently delivers hundreds of lumens per LED, allowing us to significantly reduce the number of LEDs in our designs,” comments Steve Walczak, director of engineering, Sternberg Lighting. “By using fewer LEDs, we can simplify design and production, ultimately reducing cost without sacrificing light output or quality for our end customers.”
Characterised at 85°C, the XM-L2 LED is available in 2700K to 6200K colour temperatures and offers minimum CRI options of 80, 85 and 90. What’s more, since the XM-L2 LED is a successor product to XM-L LEDs, the application of ENERGY STAR qualification requires only 3000 hours of XM-L2 LED LM-80 data, instead of the normal 6000 hours. The XM-L2 LED is also UL-recognised and features a level-4 rating.
Cree XLamp XM-L2 LED samples are available now, and production quantities are available with standard lead times.
PhotonStar LED to provide IP to major LED chip manufacturer
The patents of the British designer and manufacturer of smart LED lighting solutions are now mostly granted in Europe and are moving to the Chinese market
PhotonStar LED Group plc. has signed its first licensing agreement for its next generation chip design patents and an associated design services supply agreement, with a leading LED chip manufacturer.
The financial terms of the non-exclusive patent license agreement have not been disclosed, but are expected to start to have an impact on PhotonStar’s revenues in 2014. This is when the resulting LED chips are anticipated to brought to market by the manufacturer.
PhotonStar has a substantial IP platform, comprising a total of 15 patent families covering advanced LED chip design, optimal low cost packaging, advanced colour mixing and control. The LED chip patents dating back to 2008/9 are

now mostly granted in Europe and progressing through the international phase. The firm recently received its first Chinese patents and continues to further develop its chip IP.
James Mckenzie, CEO of PhotonStar LED Group PLC, comments, “Licensing our LED chip design IP to third parties will be a key part of our business going forward, and will be a clear demonstration of the substantial value in our IP.”
“This agreement is a major validation of our LED chip design approach and is expected to produce LED chips with extremely high levels of chip light extraction, making them some of the lowest cost and most efficient chips available on the market,” adds McKenzie.
Luminus Devices UV slim LED packages now shipping
There are two variations available, and have been designed to enable tight linear high power UV LED arrays
Luminus Devices, the innovator of Big Chip LEDs, has announced that its new UV Slim LED packages, which began sampling in May, have begun shipping as production units.
Designed specifically for high-density linear arrays, the firm says its UV Slim LED devices provide the maximum UV energy of any single-die UV LED available.
In addition to their superior performance, higher reliability, and greater energy efficiency over traditional UV mercury lamp technology, these devices also improve workplace safety and lower environmental impact by eliminating harmful byproducts such as ozone and mercury.
“The UV Slim LED represents our dedication in providing customers with the best UV LED technology available,” says Mike Lim, Director of Global Industrial and New Business at Luminus. “Customers can tightly align the UV Slim LEDs together in order to generate the highest power- density UV LED line source available, which is especially useful for line-curing applications.”
