XLamp MPL EasyWhite LED

Cree Inc. has developed lighting-class LED that can obsolete energy-inefficient light bulbs. The XLamp MPL EasyWhite LED offers the performance, color consistency and lumen density to displace conventional light sources, all in the industry's smallest package. Featuring Cree's EasyWhite innovation, the LEDs are specified like traditional light sourcessimply indicate the desired color temperature and brightness.

The multi-chip XLamp MPL EasyWhite LED is optimized for directional lighting applications, including PAR- or BR-style light bulbs. With proper system design, the MPL EasyWhite LED can deliver the required light output for a 3000-K, 75W equivalent BR-30 light bulb, but would consume 78-percent less energy than traditional incandescent technology. This would meet the efficacy and lumen-output requirements for integral LED lamps as defined by ENERGY STAR.

"Cree has virtually eliminated the need to learn and understand LED bins thanks to EasyWhite color temperatures," said Fred Dorrani, president, T^3 Mark, Inc., an LED integrator specializing in light engines. "Combined with the single-light-source design of the LED, it can simplify design and manufacturing, speeding overall time-to-market and improving product consistency."

"Cree is raising the bar on LED brightness, efficacy and ease of use. We are providing the MPL LEDs the way the lighting industry has wanted to buy LEDs," said Paul Thieken, Cree, director of marketing, LED components. "Customers using EasyWhite color temperatures can shorten the design and manufacturing cycle for new products, while improving color consistency and reducing pixelation in their product. The MPL EasyWhite LED further broadens Cree's portfolio of application-optimized LEDs, specifically designed to meet the needs of the lighting industry."

MPL EasyWhite LEDs are offered in 2700-K, 3000-K, 3500-K and 4000-K color temperatures that are in the center of the respective ANSI C78.377-2008 color bins. Due to the superior color consistency of the MPL EasyWhite LEDs, the color space occupied by each of these color temperatures is 75 percent smaller than the total area of the corresponding ANSI C78.377 color bins. This can reduce component count and eliminate complex mixing recipes and the pixilation often associated with other LED designs.

The XLamp MPL EasyWhite LED features up to 1500 lumens at 250mA and a compact 12mm x 13mm footprint, which is 72 percent smaller than the nearest-competing LED component. It is commercially available in volume now with standard lead times and in small quantities through authorized Cree distributors, as well as in sample quantities direct from Cree.
