White LEDs for retrofit lamps

10 July 2013 Opto-Electronics

New from Philips Lumileds is the 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. High efficacy of 140 lm/W is achieved for cool white light at 4000 K and minimum 80 CRI. This allows a 50 W PAR20 lamp to be achieved using only four LEDs, or a 40 W A19 lamp that previously required 14 LEDs to be created using only six.

The new mid-power LEDs are offered across a full spectrum of correlated colour temperatures (2700 K-6500 K) 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 to 1 W, delivering up to 130 lumen in the compact 3535 form factor. Rated at 100 mA, the LED can be driven up to a maximum of 200 mA. It supports ENERGY STAR certification requirements up to 25 000 hours at 85°C and 150 mA.

In addition to the expansion of its mid-power offering, Philips Lumileds also introduced its first low-power LED solution, the LUXEON 4014. This rectangular device is a high-efficacy LED designed to address linear and omnidirectional lighting applications such as under-cabinet and cove, refrigerator lighting and the retrofit LED market. Delivered in a 4,0 x 1,4 x 0,7 mm footprint, the 4014 line can achieve an efficacy of 160 lm/W at 4000 K and CRI of 80.
