XLAMP® CXA1304 LED
RELATIVE LUMINOUS FLUX
The relative luminous flux 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 400 mA at TJ = 85 °C for the 9-V CXA1304 LED.
Using the 9-V CXA1304 LED as an example, at steady-state operation of Tc = 55 °C, IF = 700 mA, the relative luminous flux ratio is 160%
in the chart below. A 9-V CXA1304 LED that measures 380 lm during binning will deliver 608 lm (380 * 1.6) at steady-state operation of
Tc = 55 °C, IF = 700 mA.
