RELATIVE LUMINOUS FLUX - CONTINUED

The relative luminous flux values provided below are the ratio of:

• Measurements of the CMB1304 Pro9 LED 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 CMB1304 Pro9 LED.

Using the 18-V CMB1304 Pro9 LED as an example, at steady-state operation of Tc = 55 °C, I

F = 300 mA, the relative luminous flux ratio is

150% in the chart below. An 18-V CMB1304 Pro9 LED that measures 501 lm during binning will deliver 752 lm (501 * 1.5) at steady-state

operation of Tc = 55 °C, I

F = 300 mA.
