Notes for Table 2:

1. Total angle at which 90% of total luminous flux is captured.

2. Viewing angle is the off axis angle from the LED centerline where the luminous intensity is ½ of the peak value.

Notes for Table 3:

1. Lumileds maintains a tolerance of ±2% on forward voltage measurements.

2. Measured between 25°C and 85°C.

3. Thermal resistance is measured between junction and the bottom of the LUXEON CoB substrate.

Notes for Table 4:

1. Proper current derating must be observed to maintain the junction temperature below the maximum allowable junction temperature.

2. Residual periodic variations due to power conversion from alternating current (AC) to direct current (DC), also called “ripple,” are acceptable if the following conditions are met:

– The frequency of the ripple current is 100Hz or higher

– The average current for each cycle does not exceed the maximum allowable DC forward current

– The maximum amplitude of the ripple does not exceed 20% of the maximum allowable DC forward current
