Power characteristics of Light Emitting
Diodes in different pulse regimes strongly depend on duty cycle. For receiving
of maximum average power we recommend using of pulse regimes with duty
cycle 50% or 25%, (but not hard CW where heating decreases power). For
receiving of maximum peak power we recommend using of short pulse (less
then 50 ms).
Here are presented typical average vs. current
and peak power vs. current characteristics of LED19 and LED22 measured
at different pulse regimes
in the range 5 µs ÷2 ms.
These characteristics are measured at repetition
rate 500 Hz. 50% duty cycle corresponds to 1 ms pulse duration. Average
vs. current and peak power vs. current characteristics for models: LED16,
LED17, LED18, LED20, LED21 and LED23 are similar.
