CXa2520 LED
RELATIVE LUMINOUS FLUX
The relative luminous ux values provided below are the ratio of:
• Measurements of CXA2520 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 550 mA at T
J
= 85 °C.
For example, at steady-state operation of Tc = 25 °C, I
F
= 725 mA, the relative luminous ux ratio is 140% in the chart
below. A CXA2520 LED that measures 2100 lm during binning will deliver 3300 lm (2940 * 1.4) at steady-state operation
of Tc = 25 °C, I
F
= 725 mA.
