CA 2182538

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 low voltage switching system that includes a solenoid operated normally open switch in which the switch is shunted across the timer controlled switch. A detector detects the presence of a person or the like in the field of view of the detector and provides an output signal in response thereto. The signal activates the solenoid thereby closing the switch to turn 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.
