Cree's XLamp MPL EasyWhite LED 'most efficient on the market'
Cree's new XLamp MPL EasyWhite LED - which has a footprint 72 per cent smaller than its nearest competitor - is a result of effective research and development, LED product marketing manager at Cree Paul Scheidt has said.
A new lighting-class light emitting diode (LED) by Cree has the potential to remove the need for energy-inefficient lightbulbs as it offers the colour consistency, lumen density and performance which conventional light sources deliver.
Cree s XLamp MPL EasyWhite LED has up to 1,500 lumens at 250 milliamps and a footprint which is 72 per cent smaller than the nearest-competing LED component. The device can deliver the required light output for a 3,000-kelvin, 75-watt-equivalent BR-30 light bulb but uses 78 per cent less energy.
As well as using less energy, the multi-chip MPL EasyWhite LED has a colour space which occupies 75 per cent less space that the total area of the corresponding ANSI C78.377 colour bins.
Such "superior" colour consistency can remove complex pixilation and mixing recipes which are sometimes associated with other LED designs.
The MPL EasyWhite LED is a further additional to the portfolio of application-optimised LEDs of Cree which are designed to meet the demands and future needs of the lighting industry.
Commenting on the superiority of the Cree product, Paul Scheidt, Cree product marketing manager for LED components, said that no other tier one LED supplier has a product that can emit the light output which the XLamp MPL can.
"A few tier two LED suppliers have LEDs with similar light output levels, but none are as efficient as XLamp MPL," Mr Scheidt stated.
All of the XLamp white LEDs are based on Cree s "industry-leading" indium gallium nitride (InGaN) blue LED die and in 2006, the future of InGaN white LEDs was 131 lumen per watt.
Cree has met and exceeded this benchmark and announced that it had achieved industry-best research and development results of 186 lumens per watt efficacy and 197 lumens of light output.
"InGaN-based white LEDs have been shown in the laboratory to be the most efficient light source that exists. This level of performance is not in mass production yet, but Cree has the proven track record in bringing these innovations to market quickly," Mr Scheidt added.
Furthermore, Cree has a track record in enabling research and development announcements to be put into production within two-three years.
The ability of Cree to put research and development findings into production so quickly could have played a part in its recent announcement that it achieved record revenue for the second quarter of its 2010 fiscal year ended December 27th 2009, standing at $199.5 million (£124.5 million).
Such revenue marked a 35 per cent increase compared to the second fiscal quarter of the previous year and an 18 per cent increase from the first quarter of fiscal 2010. Chuck Swoboda, Cree chairman and chief executive officer, said the revenue increase was down to the popularity of LED lighting adoption and the company s focus on capacity expansion and factory execution.
This, he said, allowed Cree to lead the LED "revolution".
