History of Photocells

The modern photocell has remained mainly unchanged since they were first invented and introduced over 40 years ago. The main reason they were invented was to control outdoor lighting fixtures so that they were lit dusk to dawn, therefore saving power and the bulb's lifespan. The operation of a photocell is fairly simple. There is a current flowing through a closed electromagnetic relay. When the cell is exposed to sunlight the resistance is zero and therefore there is no current flowing to the fixture. When the sunlight is gone the opposite happens and power flows freely to the light.
