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 4a. Typical forward current vs. forward voltage). 3. Measured between T c=80°C and Tc=90°C at binning current. 4. Rθ j-c el: Electrical thermal resistance (junction to case). 5. Rθ j-c real: Real thermal resistance (junction to case) with wall plug efficiency included. Reference JESD51-51, JESD51-14, 4.1.3. |
