CXa1816 LED
RELATIVE LUMINOUS FLUX
The relative luminous ux values provided below are the ratio of:
• Measurements of CXA1816 at steady‑state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 450mA at T
J
= 85°C.
For example, at steady‑state operation of Tc = 105°C, I
F
= 380mA, the relative luminous ux ratio is 80% in the chart below. A CXA1816
LED that measures 2100lm during binning will deliver 1680lm (2100 * 0.8) at steady‑state operation of Tc = 105°C, I
F
= 380mA.
