Lumileds targets reduction in LED component count for lamps

Philips Lumileds has introduced the two-die Luxeon 3535 2D mid-power LEDs that, among other potential usages, can lower component count in retrofit lamp designs. The company also announced its first low-power LED, the Luxeon 4014, that targets linear application such as under-cabinet and cove lighting. The new mid-power devices deliver efficacy of 140 lm/W at 4000K and 100 mA of driver current – outputting a minimum of 60 lm. You can generally get 75% more lumen output by driving the devices at 200 mA. Lumileds said that maximum output is 130 lm. Efficacy drops by 20% at 200 mA.
