Solar garden lamp by CDS photocell control

Reverse engineered circuit diagram of yet another commercially produced solar garden lamp. This one depends upon a CDS photocell to turn the light on at night, and although more complex than the circuits, it allows the battery to charge more efficiently.

Solar garden LED light and single NiCd AA charger

More Solar LED Light

Another Reverse engineered circuit diagram of a mass produced solar LED light. This light also automatically turns on when there is no light falling upon the solar cell but this circuit waits untill it gets bit darker outside than the one above. Although battery charging is through a schottky diode, some charging efficiency is lost in the 330 ohm resistor during daylight time.

Solar Cell charges a NiCd AA cell when darkness falls

Reverse engineered circuit diagram of a popular mass produced solar light. The light automatically turns on when there is no light falling upon the solar cell, so the parts count is minimal. The charging circiut is not particularly efficient since the battery must charge through a plain diode.
