ABSTRACT:
A photocell device for use with an exterior landscape lighting assembly. The lighting assembly includes a transformer having an input line connected to an electrical power source. The transformer converts a primary electrical voltage to a secondary electrical voltage which is in turn outputted through an output line connecting to a plurality of individual lighting units. The photocell device includes a turf stake capable of engaging into a ground location. An enclosure is mounted atop the turf stake and includes a power supply circuit, a photo sensor and control circuitry communicating with the photo sensor. The power supply circuit converts the secondary transformer output to an unregulated and filtered direct current suitable for powering the control circuitry. The control circuitry interfaces with the photo sensor and, in response thereto, selectively activates and deactivates the plurality of lighting elements. The control circuitry further includes such features as timer and dimmer capability and also may include software algorithmic capability for approximating a real time input signal and operating the lighting units responsive to the input signal.
