Modification of a Typical Solar Path Light __ Circuit

Modification of a typical solar path light with a standard 1000ma-hour NiMH AAA cell. I then replaced the small 4 cell solar panel with a larger 4 cell unit, which produced 150ma in the sun. Next, I simply changed the 470uH coil on the circuit board to a 22uH coil. The lower inductance increased the battery current to 40ma when the LED light was on, which translated to about 13ma LED current.

Hack your solar garden lights. - bigclive.com

These chips are very ingenious. They contain a diode for charging the single NiMh cell from the solar panel, but also use the voltage from the solar panel to detect when it's dark enough to turn the light on. The circuit pulses a small inductor at about 100kHz to step up the voltage to drive the LED in a similar style to a Joule Thief circuit.

How does a solar garden LED work with just 1 AAA battery

The first is an IC such as the QX5251. This is a solar battery charger and LED driver in a TO-94 package. It rectifies the solar input as well as detects when it is dark in order to activate the LED. The second is an inductor which the driver uses to boost the voltage from the battery high enough to light the LED.
