Hello, I am trying to work up a schematic for a project.
The project involves running 2 30ma LEDS off of line voltage. The LEDs will be powered off line voltage until power is lost, then I need to power the LEDs of a small coin cell battery for about 2 hours, until the cycle starts again. The added kick to the project is that the circuit must be no more than 4mm in height; I can remotely move the battery to another location that I have some space 20mmx20mmx40mm.
Question can someone help me design a circuit up to accomplish this in a timely manor. I would be willing to compensate you for your time. I am sure I need to supply more details and can do so if needed,
Thanks in advance.
