Multichip white LEDs

28 April 2010 Opto-Electronics

Cree has developed a new lighting-class LED targeted at replacing energy-inefficient light bulbs. The XLamp MPL EasyWhite LED offers high performance, colour consistency and lumen density in a 12 x 13 mm footprint. Featuring Cree’s EasyWhite innovation, the LEDs are specified like traditional light sources – by simply indicating the desired colour temperature and brightness. The new LEDs feature up to 1500 lumens at 250 mA.

The multichip XLamp MPL is optimised for directional lighting applications, including PAR- or BR-style light bulbs. With proper system design, the LED can deliver the required light output for a 3000 K, 75 W 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.

MPL EasyWhite LEDs are offered in 2700 K, 3000 K, 3500 K and 4000 K colour temperatures that are in the centre of the respective ANSI C78.377-2008 colour bins. Due to the high colour consistency of the 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 can reduce component count and eliminate complex mixing recipes and the pixilation often associated with other LED designs.
