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.

"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-power LEDs are offered across a full spectrum of correlated color temperatures (2700K-6500K) with a minimum CRI of 80. Versions with CRI 70 for outdoor applications and CRI 90 for high end indoor applications are planned for future release.

The Luxeon 3535 2D line operates at 0.5–1W, delivering up to 130 lumens in the compact 3535 form factor. Rated at 100mA, the Luxeon 3535 2D can be driven up to a maximum of 200mA. Luxeon 3535 2D supports ENERGY STAR certification requirements up to 25,000 hours at 85 degrees C and 150mA.

Philips Lumileds has also introduced its first low-power LED, the Luxeon 4014. This rectangular, high efficacy LED was designed to specifically address linear and omnidirectional lighting applications such as under-cabinet and cove, refrigerator lighting and the retrofit LED market. Delivered in a 4.0mm x 1.4mm x 0.7mm footprint, the LUXEON 4014 line can achieve an efficacy of 160lm/W at 4000K and CRI of 80.
