[Category : - ELECTRICITY & LIGHTING]
[Viewed 571 times]

A lighting system includes a light emitting element operable to emit light at a level between zero and 100 percent, a light level sensor positioned to detect a total level of light, and a motion detector positioned to detect a motion in a predefined space. A controller is coupled to the light emitting element, the light level sensor, and the motion detector and is operable to compare a measured total level of light to a set point and to activate the light emitting element in response to the measured total light level being below the setpoint. The controller is further operable to activate the light emitting element in response to the detection of motion within the space. The controller has a first mode that activates the light emitting element using a discrete signal, and a second mode that activates the light emitting element using an analog signal.
