Taking aim at inefficient light bulbs
LED lighting specialist, Cree, has announced what it describes as a breakthrough new lighting class LED that it claims could make energy inefficient light bulbs obsolete.
Cree says that its XLamp MPL EasyWhite LED offers the performance, colour consistency and lumen density to displace conventional light sources, in 'the industry's smallest package'.
The LEDs are specified as per traditional light sources and users indicate the desired colour temperature and brightness.
The device is optimised for directional lighting applications, including PAR- or BR-style light bulbs. According to Cree, with proper system design, the MPL EasyWhite LED can deliver the required light output for a 3000K, 75W equivalent BR-30 light bulb, but would consume 78% less energy than traditional incandescent technology. This would meet the efficacy and lumen output requirements for integral LED lamps as defined by Energy Star.
Paul Thieken, Cree, director of marketing, LED components, said: "Cree is raising the bar on LED brightness, efficacy and ease of use. Customers using EasyWhite colour temperatures can shorten the design and manufacturing cycle for new products, while improving colour consistency and reducing pixelation in their product. The MPL EasyWhite LED further broadens Cree's portfolio of application optimised LEDs, specifically designed to meet the needs of the lighting industry."
The LEDs are available in 2700, 3000, 3500 and 4000K colour temperatures that are in the centre of the respective ANSI C78.377-2008 colour bins. Thieken says that due to the superior colour consistency of the MPL EasyWhite LEDs, the colour space occupied by each of these colour temperatures is 75% smaller than the total area of the corresponding ANSI C78.377 colour bins.
This, notes Thieken, can reduce component count and eliminate complex mixing recipes and the pixilation often associated with other LED designs.
