CXa3070 LED
RELATIVE LUMINOUS FLUX
The relative luminous ux values provided below are the ratio of:
• Measurements of CXA3070 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 1900 mA at T
J
= 85 °C.
For example, at steady-state operation of Tc = 25 °C, I
F
= 1300 mA, the relative luminous ux ratio is 80% in the chart
below. A CXA3070 LED that measures 8500 lm during binning will deliver 6800 lm (8500 * 0.8) at steady-state operation
of Tc = 25 °C, I
F
= 1300 mA.
