CXa1304 LED
RELATIVE LUMINOUS FLUX - CONTINUED
The relative luminous ux values provided below are the ratio of:
• Measurements of CXA1304 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 18-V CXA1304 LED.
Using the 18-V CXA1304 LED as an example, at steady-state operation of Tc = 55 °C, I
F
= 350 mA, the relative luminous
ux ratio is 160% in the chart below. An 18‑V CXA1304 LED that measures 380 lm during binning will deliver 608 lm
(380 * 1.6) at steady-state operation of Tc = 55 °C, I
F
= 350 mA.
