摘要： A dusk delay system for outdoor motion detection provides the benefits of dusk to dawn, timed, and motion detection control. A dusk to dawn type sensor detects the onset of darkness and turns on the lights for a predetermined duration of time. Once the duration of time expires, the lights will be shut off. Subsequently, motion within the monitored area will be detected by a motion detector and cause the light to be turned on for a selectably predetermined amount of time. The timer can randomize the actual time in which the lighting controller shuts off the light and goes into the motion detection mode. A latch mechanism disables the operation of the system upon momentary interruption of the power.

摘要： The decorative fixtures of the present invention enable azimuthal directivity of the infrared detector in order to adjust the directivity of the infrared detector about a vertical axis in a manner which is aesthetically compatible with the decorative nature of the fixture. In one embodiment, a hexagonal fixture is turnable about a horizontal axis to pivot not only the infrared detector, but the motion detection circuitry as well. In another embodiment, the motion detection circuitry and the infrared detector are physically separate within the decorative fixture, enabling the infrared detector to pivot within a circular portion of the decorative fixture.
摘要翻译： 本发明的装饰装置使得红外线检测器的方位指向性能够以与固定装置的装饰性质在美学上相容的方式围绕垂直轴线调节红外探测器的方向性。 在一个实施例中，六边形夹具可绕水平轴线转动，不仅枢转红外检测器，而且还可以运动检测电路。 在另一个实施例中，运动检测电路和红外检测器在装饰夹具内物理分离，使得红外检测器能够在装饰固定装置的圆形部分内枢转。

摘要： The socket/tab supported light fixture preferably incorporates a fluorescent lamp within an elongated housing that has projecting blades to be received in an electrical wall socket. The housing incorporates a tab extending to overlie the face plate screw of the wall socket, the tab including an opening to receive the face plate screw thereby to attach the light fixture to the wall socket. The light fixture also preferably includes an elongated pivoting shade that may be moved to adjust the illumination level provided by the light fixture to at least a portion of the illuminated area.
