I have a conventional yard flood light that is now giving me a problem. The problem is that the timer that can be set to determine the amount of time that the light stays on is not working correctly all of the time.
I can have the light connected and it works well for 5 days then for some reason the light does not shut off and stays on all night. When I manual shut off the light (cut the power) then turn the power back on it will function correctly for a few days and then will not shut off again. All other functions are working OK.
I am hoping that some one might be able to start me off in getting this light working well again.
In the interest of providing additional information which might be of help I have included the following as well as an image of the flood light!
This unit contains three small pots which can be set to ones requirements.
The electronics is provided on 2-small boards, one for the AC-DC conversion the other the circuitry for the flood light.
I removed the electronics from the light and it consists of the following:
A power supply board which contains:
A relay switch 7amps AC 250 Volts, as well as the expected 4 power supply diodes and 3 large capacitors, a transistor and a few resisters.
The electronics board contain the following
1-LM432N IC
1- IR Detector
1- Photo resister
3 Pots for setting the sensitivity of the IFR Sensor, sensitivity to the Photo resister and finally a Pot for setting the Light On duration.
( It is here that I have the problem).
I thank you in advance for any assistance you might be able to provide.
