I have a LED spot light from a old garden solar light. The light was powered by a 12V battery connected to a LED driver. The driver / charge controller os fried.
The light has 36 large white LEDs. 12 rows of 3 LEDs in series.
The Sarge has already me a lot of help on this in another thread and we have determined that the driver had a PT4115. According to the datasheet and sensing resistor, it was putting out 606 ma,
I have tried contacting the totally worthless Silicon Solar (even their email does not work properly) and they tell me they know nothing about the type of LED in this light.
I would like to make use of the light in an upcoming project.
I do not know if I have enough confidence to build a buck regulator from scratch and was thinking of using a Buck Puck.
The one I have in mind has an adjustable current through an internal trim resistor. A really nice feature of this device is it solves a second problem supplying regulated 5VDC for a PIC that I intend to include in the project.
Has anyone had experience with these devices? What are the chances it will work with these unknown LEDs? Is it a matter of working ot not working or are there long term effects that may occur? The only thing I can think of is if I did not calculate the current correctly and but stress on those LEDs shortening their life.
