CXa3590 LED
RELATIVE LUMINOUS FLUX - CONTINUED
The relative luminous ux values provided below are the ratio of:
• Measurements of CXA3590 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 1200 mA at T
J
= 85 °C for the 72-V CXA3590.
Using the 72-V CXA3590 LED as an example, at steady-state operation of Tc = 105 °C, I
F
= 1200 mA, the relative
luminous ux ratio is 90% in the chart below. A CXA3590 LED that measures 11,000 lm during binning will deliver
9,900 lm (11,000 * 0.9) at steady-state operation of Tc = 105 °C, I
F
= 1200 mA.
