CXa2530 LED
RELATIVE LUMINOUS FLUX VS. CURRENT (T
J
= 85 °C)
The relative luminous ux values provided below are the ratio of:
• Measurements of CXA2530 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 800 mA at T
J
= 85 °C.
For example, at steady-state operation of Tc = 85 °C, I
F
= 1080 mA, the relative luminous ux ratio is 120% in the
chart below. A CXA2530 LED that measures 3200 lm during binning will deliver 3840 lm (3200 * 1.2) at steady-state
operation of Tc = 85 °C, I
F
= 1080 mA.
