CXa1520 LED
RELATIVE LUMINOUS FLUX
The relative luminous ux values provided below are the ratio of:
• Measurements of CXA1520 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 500 mA at T
J
= 85 °C.
For example, at steady-state operation of Tc = 105 °C, I
F
= 700 mA, the relative luminous ux ratio is 120% in the
chart below. A CXA1520 LED that measures 2100 lm during binning will deliver 2520 lm (2100 * 1.2) at steady-state
operation of Tc = 105 °C, I
F
= 700 mA.
