This soldering kit contains all the parts needed to build a solar-powered night light. For this purpose, the components supplied are simply soldered together with a little solder. The circuit is already built and ready for use. The function of the circuit: During the day, the energy generated by the solar cell is stored in the battery and supplies a warm white LED with approx. 25 mA, which switches on automatically in the evening at dusk. Depending on the charge level of the battery, the LED lights up all night. If the battery is largely discharged, the LED is switched off, which prevents a deep discharge of the battery and thus significantly extends the life cycle of the battery. Application: Solar garden light, solar house number light, solar night light, lighting for birdhouses and decorative objects and much more around the house and garden.
