ABSTRACT:
An outdoor ground lighting system that includes one or more low voltage lamp units, provided from a step down transformer connectable to a high voltage AC power supply and an on/off timer operative to turn the lamps on for a selected time period during hours of darkness. Added to this known system is a secondary switching system that includes a solenoid operated switch connected to bypass the timer and a detector to detect the presence of a person or the like in the field of view of the detector. The detector provides an output signal in response to detecting the presence of someone and the solenoid switch is actuated by such signal to switch on the lamps when the timer is in the off cycle. The secondary switching system enhances the garden lighting system by providing a security lighting system when the timer is in an off mode.
