I have 2 LED drivers that I want to drive my LED unit with. One driver is of higher constant current than the other. Both drivers will never be on at the same time. The output of driver 1 and the output of driver 2 will be joined together in parallel and then connected to the input of the LED unit. As a pre-caution I want to add a 1N4007 signal rectifier diode on the positive output of each driver so that current only goes out. Wiring it up without the diodes work fine, but when i put the diodes, I noticed that the diodes do get a little warm. the one linked to the higher current driver gets much hotter. The diodes are supposed to be able to handle 1A. Would it be better to maybe add the 1N5408 which are supposed to be able to handle 3A. Will the heat be much less on a 3A one as apposed to a 1A one?
Just wondering what would happen to a 1N4007 if it overheated or burnt out and damaged? what would it do to the current flowing through it? Would completely leaving out the 1N4007 be a better option? without the 1N4007, each driver can send current through the output of the other driver, will that effect the other driver? do drivers reject current coming in from the output?
Thanks
