    • A lighting control system for a space equipped with lamps for illuminating the space comprises a power circuit for supplying power to the lamps, a controllable switch in the power circuit for turning the lamps on and off, an occupancy sensor for detecting motion within the space and generating a motion-detected control signal in response to the detection of such motion, and a timer for measuring a time-out interval following the generation of the motion-detected control signal by the occupancy sensor and producing a time-out control signal in response to completion of the measurement of the time-out interval. A processor receives the control signals from the occupancy sensor and the timer and produces a switch-off control signal for the controllable switch to turn the lamps off in response to the time-out control signal, modifies the time-out interval by a time-out offset value in response to preselected events, counts the number of times the switch-off control signal is produced, without the receipt of the motion-detected control signal, within a predetermined time following the end of the time-out interval, and decrements the time-out interval by the offset value in response to the count reaching a predetermined value.
    • 一种用于照明空间的灯的照明控制系统,包括用于向灯供电的电源电路,用于打开和关闭灯的电源电路中的可控开关,用于检测空间内的运动的占用传感器, 响应于这种运动的检测而产生运动检测控制信号;以及定时器,用于测量占用传感器产生运动检测控制信号之后的超时间隔,并产生响应中的超时控制信号 完成超时间隔的测量。 处理器接收来自占用传感器和定时器的控制信号,并产生用于可控开关的断开控制信号,以响应于超时控制信号而关闭灯,并将时间间隔修改, 响应于预先选择的事件输出偏移值,在超时间间隔结束之后的预定时间内计数切断控制信号的次数,而不接收运动检测控制信号,并且减少 响应于计数达到预定值的偏移值的超时间隔。
