ABSTRACT:
Solar powered outdoor lighting and/or alarm systems are provided and include a light source or alarm, a passive infrared (PIR) sensor in conjunction with a battery recharged via solar cells, and a control circuit coupled to the light source or alarm, the PIR sensor, and the rechargeable battery. The control circuit guarantees that the light source or alarm is turned on by the battery only when the sensor senses the presence of a moving target. The systems may include a light detector which is utilized to prevent the system from activating in daylight. In the case of a lighting system, a timer is utilized to turn off a lamp after a desired period of time (e.g. 3 minutes). By limiting the "on-time" of the light source, a two to five watt bulb may be used. In the case of an alarm, the alarm may be hardwired to the control circuit; or if desired, a transmitter powered by the rechargeable battery may be used to transmit an alarm signal to a remote receiver. The receiver is in turn coupled to its own power supply and to a control circuit which controls or switches desired components such as horns, bells, lights, etc.
