Philips Luxeon K2
Philips Lumileds has announced its new cool-white Luxeon K2 with TFFC LED. Chip and packaging advancements by the company enable extended capabilities that deliver maximum performance in any environment. Luxeon K2 with TFFC is the only LED designed, binned and tested for standard operation at 1000mA and capable of being driven at 1500mA. Thin Film Flip Chip (TFFC) technology contributes to
overall light output improvement, excellent optical performance and improved thermal capability.
New packaging advancements improve an already rugged and capable package and deliver the lowest
thermal resistance, 5.5° C/W, of any power LED; lower thermal resistance allows the LED to be driven at higher currents and lowers thermal management engineering efforts and costs.
Light output performance from a Luxeon K2 with TFFC part binned and tested for 160 lumens minimum and 1A drive current can easily exceed 220 lumens at higher drive currents.
At its rated drive current, Luxeon K2 with TFFC operates at only 66% of its maximum power rating and delivers high-level performance for a single 1mm2 chip.
