CXa1507 LED
RELATIVE LUMINOUS FLUX - CONTINUED
The relative luminous ux values provided below are the ratio of:
• Measurements of CXA1507 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 200 mA at T
J
= 85 °C for the 36-V CXA1507 LED.
Using the 36-V CXA1507 LED as an example, at steady-state operation of Tc = 25 °C, I
F
= 325 mA, the relative luminous
ux ratio is 150% in the chart below. A CXA1507 LED that measures 710 lm during binning will deliver 1136 lm (710 *
1.6) at steady-state operation of Tc = 25 °C, I
F
= 325 mA.
