How Does Solar Yard Lighting Work?
Solar yard lighting consists of a few basic components. There are five major components: a solar cell, a tiny controller board, a photoresistor, an LED light source and a Nicad battery (usually AA). “LED” is short for “light emitting diode”. A light emitting diodes are extremely small light bulbs that fit into electronic circuitry. Light emitting diodes are different than normal light bulbs, though. First, they don’t get very hot in comparison to a light bulb. Just as important, light emitting diodes don’t burn out. Electrons in the diode’s semiconductor material are what causes the diode to radiate light. LED light sources are what make the solar yard lights radiate at night. The solar cell is what collects light during the day, when the Sun is shining on the solar yard lights. This solar cell conducts light to the AA Nicad battery, which is made to store up solar energy. When it gets night time, the battery is able to power the LED light source all night. Meanwhile, the controller bo
