PCT No. PCT/GB97/01845 Sec. 371 Date Jun. 3, 1999 Sec. 102(e) Date Jun. 3, 1999 PCT Filed Jul. 9, 1997 PCT Pub. No. WO98/01699 PCT Pub. Date Jan. 15, 1998An outdoor solar lamp has a stand (10), with a foot (11), that supports a solar cell panel (12) in a housing (13). A passive infrared motion detector (14) is mounted in a peripheral surface of the housing (13). Incandescent lamps and a halogen lamp (not shown) are supported behind diffusers (15 and 16) respectively. The incandescent lamps operate automatically to be turned ON and OFF as required in a generally known manner. The halogen lamp is provided for security and is controlled to be turned ON when motion is sensed by the detector (14) to illuminate and indicate the presence of an intruder. A security mode of the halogen lamp is armed and disarmed remotely, using a handheld infrared transmitter. |
