Using a multi-chip package, Cree has developed an LED that will compete with 75W light bulbs.
Dubbed XLamp MPL, the 12x13mm device will eventually deliver up to 1,500 lm at 750mA, which is 75 lm/W.
Each device has three strings of eight die and at 750mA, 250mA per string, forward voltage is typically 26.5V.
This said, the data sheet focusses on 150mA/string operation where voltage drop is typically 25V and output is 700-900 lm depending on bin, with future bins planned up to 1,100-1,200 lm at 3x150mA.
Colour binning has been simplified, under the firm’s EasyWhite brand, by offering the LEDs in 2,700, 3,000, 3,500 and 4,000K colour temperatures that are in the centre of the respective ANSI C78.377-2008 bins.
The colour space occupied by each of these colour temperatures is claimed to be 75% smaller than the total area of the corresponding ANSI C78.377 bins.
“Cree has virtually eliminated the need to learn and understand LED bins thanks to EasyWhite colour temperatures,” said a spokesman for Cree.
The package is optimised for directional lighting applications, including PAR- or BR-style light bulbs.
“With proper system design, the MPL can deliver the required light output for a 3,000K, 75W equivalent BR-30 light bulb, but would consume 78% less energy than traditional incandescent technology,” said Cree.
