‘Extreme density’ LED
18 April 2018
Opto-Electronics
Cree recently announced the commercial availability of the XLamp XD16 LED – what it describes as an ‘extreme density’ LED – which delivers up to five and a half times higher lumen density than its previous generation of high-power LEDs.
Built on Cree’s advanced NX technology platform, the XD16 combines high lumen density, low optical cross-talk, enhanced thermal contact and ease of system manufacturing to enable innovative new designs for a broad spectrum of lighting applications, such as colour tuning, street, portable and industrial.
The ceramic-based LED delivers a lumen density of more than 284 lumens per square millimetre. It utilises the proven XQ footprint and successfully addresses challenges with luminaire manufacturing, thermal design, optical design and reliability faced by competing LEDs. For example, Cree claims the XD16 reduces system-level optical loss by up to three times versus competing technologies when LEDs are placed close together on a board. This improvement translates into fewer wasted lumens and higher efficacy for lighting products.
The new LEDs are characterised and binned at 85°C, available in ANSI White, EasyWhite 3- and 5-step colour temperatures (2700K – 6500K), and CRI options of 70, 80 and 90.
