Solar Garden Light Dust till Dawn – 2, 27LED Torch conversion



Been making quite a few of these night lights and been trying out various combinations of Inductors with the QX5252F LED Driver IC….

So here is the latest version using the QX5252F LED Driver IC, a 33uH Inductor and a 1N4148 Diode feeding pulsed DC voltage to a 27LED Torch PCB…With a switch to switch between 24LEDs or 3LEDs or simply OFF….In off position the charging will still happen.

I have used a 5V/100mAh solar module on this project because it seemed in testing to provide a good charge in mixed cloudy and sunny conditions and it fits my project box…which is originally a plastic box for paperclips…

With a charged battery at 1,37v and 700mAh the 24 LEDs will shine through the night no problem…

Final modification done on this DTD light..Now using 100uH (original solar garden light) Inductor and a 50v/22uf ceramic capacitor directly before the PCB plus and minus. Works really well for my setup…

Enjoy….
