Lumileds maintains a tolerance of +/-0.06 Volts per LED for voltage measurements. 2. Dynamic resistance is the inverse of the slope in linear forward voltage model for LEDs. See Figures 2a and 2b. 3. Measured between 25oC ≤ T J ≤ 110 oC at I F = 700mA. 4. To determine the junction temperature, multiply by total array power. For best optical and lifetime performance, additional heat sinking is required. Notes: 1. Proper current derating must be observed to maintain junction temperature below the maximum. For more information, consult Luxeon OEM Guide, available upon request. 2. LEDs are not designed to be driven in reverse bias. Please consult Lumileds’ Application Brief AB11 for further information. 0.0 0.2 0.4 0.6 0.8 1.0 400 450 500 550 600 650 700 Wavelength (nm) RE D AM BE R BLUE GR E E N CY AN Figure 1a.
