Irradiance stability of the four single color LED arrays and one
RGB array under 10 ms pulse operations are made.
The nature of time-dependent irradiance achieved form five arrays is similar.
For illustration, only results of the red array are shown, Fig. 6.
Owing to
the current recovery nature of the employed high voltage power supply, current outputs during the first 2 ms of operation are
slightly fluctuating. So on the time axis we show the plots having
8 ms duration, between the 2 ms and 10 ms points.
