Philips Lumileds' latest mid-power LEDs achieve up to 140lm/W efficacy for ... - Semiconductor Today

Philips Lumileds’ latest mid-power LEDs achieve up to 140lm/W efficacy for cool white light at 4000K LED maker Philips Lumileds of San Jose, CA, USA has introduced its Luxeon 3535 2D, which combines two LED chips in a package to enable reduction in LED count and cost of designing retrofit lamps, consumer downlights and diffuse industrial lamps, says the firm. Best-in-class efficacy of 140lm/W is achieved for cool white light at 4000K and minimum 80 CRI. Picture: Luxeon 3535 2D. "This is an exciting breakthrough, because lighting designers can take advantage of a high lumen package with high efficacy while using significantly fewer chips per fixture," says Rahul Bammi, VP of product management. "For example, a 50W PAR20 lamp can be achieved using only four LEDs. Alternatively, a 40W A19 lamp that previously required 14 LEDs can now be created using only six." The new mid-po...
