IR LED series without resistor

Postby nima » Mon Aug 26, 2013 3:52 pm


I am making an IR light with two line of 24 LEDs (10x 8mm 3-Chips 200mW Infrared (IR) 850nm LED (60deg a pack of 10)) which would be 48 LEDs in total.
I am thinking of having 6 string of 4 LED in each line, It would be great if I can have the whole circuit without any resistors.
Is there any suggestion of what power supply will suite this config and is it feasible?
Any better config?

Why not use a single 3watt or 5watt IR lED instead. It is easy to implement. Use a 5W driver for a 3W IR LED or two 3W driver for a 5W IR LED ... D-P58.aspx ... D-P59.aspx

Led driver: ... d%20driver

Focus mirror: ... reflection
