Philips Lumileds and Cree lntroduce multiple new LED lines
The Philips Lumileds Luxeon M is designed to simplify luminaires designed for street- and area-lighting, and industrial applications by enabling the use of fewer components. Indeed the packaged devices with four emitters can output as much as 1100 lm depending on color temperature. For more

http://www.qs-tech.comThe input voltage for the LEDs is typically 11.2V – the sum of the forward voltage of the four series emitters. That mid-level voltage can also simplify driver design by eliminating the need for the greater voltage drop needed to power a single large emitter at 3-4V. For more

http://www.qs-tech.comPhilips will offer the LEDs in 3000K, 4000K, and 5700K CCTs, and with a minimum CRI of 70. The LEDs are hot tested and binned at 85°C. Distributor Future Lighting Solutions has the component in stock.
Cree HV LEDs
Cree, meanwhile, continues to build out an LED portfolio on what the company is calling its third-generation, silicon-carbide manufacturing platform that has been branded SC3. The new XT-E and XM-L LEDs deliver 22% more lumens than previous products in the same family, maxing out at 647 lm in cool white at 6W.
The new Cree LEDs use the same top level product designators as similar HV-LED products announced last October, although the new versions bring the aforementioned brightness advantage. Cree fabricates the LEDs as a single die and then segregates the single die into an array of series-connected emitters in the back end of the manufacturing process. You can see the array of 16 emitters if you carefully examine the nearby photo.
The array allows the LEDs to operate from 48V inputs greatly simplifying the driver design by minimizing the drop from line-voltage level. That high-voltage characteristic will enable usage of the LEDs in small SSL applications indoors and out. For more information, please visit
http://www.qs-tech.comThe XT-E LEDs are designed to be driven at 3W and deliver 275-357 lm depending on color temperature. The 6W XM-L family outputs 555-647 lm. The products share the same manufacturing technology platform as the new smaller XB-D family announced in January and the standard-voltage XT-E LEDs announced in February.
