esebm Posted June 30, 2005 Report Share Posted June 30, 2005 Hi,I'm new to this forum and my request may seem trivial. I am looking for a schematic for an Automatic LED Nite Lite made by Amertac. Does anyone have any idea where I could get that?Thanks,Ed Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted July 1, 2005 Report Share Posted July 1, 2005 We could get similar Circuits for you but that one is proprietary. Quote Link to comment Share on other sites More sharing options...

esebm Posted July 1, 2005 Author Report Share Posted July 1, 2005 Hey Wizard,Thanks lot for the schematics. The problem is that I have about 10 of these nite lights that need to be fixed. That's why I am trying to find the original schematic.Ed Quote Link to comment Share on other sites More sharing options...
ante Posted July 1, 2005 Report Share Posted July 1, 2005 Hi Ed,What’s wrong with these gizmos, they can’t be very complicated can they? Maybe you can post a close up picture and someone might have an idea for you. Quote Link to comment Share on other sites More sharing options...
esebm Posted July 1, 2005 Author Report Share Posted July 1, 2005 No,They're not overly complicated but all the relevant parts (Transistor, Triac) have no type printed on them. Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted July 1, 2005 Report Share Posted July 1, 2005 Send detailed Pictures of the board and we may be able to make a schematic from it.You know Reverse Engineer it. Quote Link to comment Share on other sites More sharing options...
ante Posted July 2, 2005 Report Share Posted July 2, 2005 It’s a challenge, try to make them better! ;D Quote Link to comment Share on other sites More sharing options...
audioguru Posted July 2, 2005 Report Share Posted July 2, 2005 You will probably find the triac blown. They use cheap triacs to meet the cheap product's price, and for small size.An incandescent lightbulb draws 10 times more current when cool than its very high temperature operating current, and a very high current when the filiament burns out or breaks and it arcs.The triacs that are used are not designed for such high currents, but some are lucky and survive somehow. If you use a more powerful triac (if it fits in there) it should last forever. ;D Quote Link to comment Share on other sites More sharing options...
esebm Posted July 2, 2005 Author Report Share Posted July 2, 2005 As Ante said, it's a challenge and I want to fix them.I agree that it might be the triac, althought these things don't use lightbulbs but LEDs. Quote Link to comment Share on other sites More sharing options...
