Philips Lumileds maintains a tolerance of ±0.06V on forward voltage measurements 2. Dynamic resistance is the inverse of the slope in linear forward voltage model for LEDs. See figure 13. 3. The forward voltage of the LUXEON K2 with TFFC LED will reduce by up to 0.50V at 1000mA during the first few hours of operation after SMT reflow. Due to this effect, Philips Lumileds recommends current source drive for consistent and reliable performance. Cross connected series/parallel arrays or voltage drivers which could result in current hogging or variation in drive current are not recommended. Please consult your Philips Lumileds authorized distributor or Philips Lumileds Sales Representative for further information. 4. Luxeon K2 with TFFC is tested and binned at 25°C with a 20ms monopulse test to minimize heating of the junction or case.
