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 load to a secondary electrical load which is in turn outputted through an output line connecting to a plurality of individual lighting units. The photocell device is capable of being mounted at an appropriate exterior location, such as to the side of a building structure. An enclosure unit includes a power supply circuit, a photo sensor and control circuitry communicating with the photo sensor. At least one light permissive window is formed within a selected front facing and/or top facing surface of the enclosure unit. 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 receiving a selected real time input signal and operating the lighting units responsive to the input signal.
