I would like to use a discarded 3 VDC transformer. However it is rated at 600mA not the recomended 300mA.
How does / will that affect the SFH 485P LED's?
I used the LED Assembly Wizard and have the following results:
Power Supply = 3 V
LED Forward Voltage = 1.5 V
LED Forward Current = 50 mA (they are rated at 100mA)
P: Parallel Assembly
Thee 30 Ohm Resistors
Total Current in Assembly = 150 mA
So will I damage or shorten the life of the IR LED's ?
Or should I just go the rechargeable battery rout?
