To drive the LED we recommend the following basic circuit connections:
LED basic circuit connection

LED with thermoelectric module basic circuit connection

LEDPulse
generator

thermocooler

1 Ohm

I adjust
Constant current source

We recommend using Quasi Continuous Wave (qCW) mode with a duty cycle 50% or 25% to obtain maximum
average optical power and short Pulse modes to obtain maximum peak power. Hard CW (continius wave) mode isNOT recommended.

IMPORTANT CAUTIONS:●●●●

please check your connection circuit before turning on the LED;
please mind the LED polarity: anode is marked with a RED dot; REVERSE voltage applying is FORBIDDEN;
please do not connect the LED to the multimeter;
please control the CURRENT applied to the LED in order NOT to EXCEED the maximum allowable values.
