Hi all.
I am hoping someone can point me in the right direction with a "problem" I am having. The scenario is that I have a constant current, voltage regulated 3 channel rgb driver which I run of a 12v ps. Each diode has its own current pot and voltage regulator. The regulator for the red and green gets very hot since these use very little of the 12v supplied. Its not a problem for the 405nm laser since it only has to "eat" 4-5 volts.
Now my question is if it is possible to drop the voltage using 1n400x diodes in series connected right before (+), or after the diode (-), to drop the voltage so less heat is generated. Is there anything I have to be aware of when connecting things this way. Obviously I dont want to fry my lasers and I havent really been able to find any info on using diodes this way, since I dont want to drop the overall voltage.
Hope someone can shed some light on this.
Thx in advance.
