Reverse Voltage LUXEON CoB is not designed to be driven in reverse bias
Notes for Table 4:
1. Proper current derating must be observed to maintain junction temperature below the maximum, please see preliminary application brief for additional information on thermal measurement
guidelines.
2. Residual periodic variations due to power conversion from alternating current (AC) to direct current (DC), also called “ripple’, with frequencies ≥100 Hz and amplitude ±20% are acceptable,
assuming the average current throughout each cycle does not exceed 2x test I
