i give my diode today. i test it run now. i use LPC826 and axiz. the driver LM317 constant current mode. i use 3.4 ohm resistor but the supply voltage for diode is high then 2.2 volt. i measure 2.8 volt and the current is 420 ma 0.42 Amp.
is it problem ?? is this voltage will kill my diode in the future or not?
i am change current resistor increase 9.5 ohm and then the diode voltage down to 2.2 volt. ok but the current down 160 ma. i have a power loss.. Please give me a idea for this operation? Help please..
i calculate the power. is it right ?
2.2 volt and 0.16 amp. Power = V x I ---> Power = 2.2 x 0.16 ---> Power = 352 miliwatt = 0.35 watt ?? is it right?
Do you have a table for LPC 826 operation voltage and amps?
