Abstract

A lighting control system comprising: at least two luminaires (12), a control unit (14) coupled to the at least two luminaires (12) by a communication link (16), by which control unit a respective illuminance of the at least two luminaires (12) can be varied, and comprising at least two sensors (18). Each of the at least two luminaires (12) is assigned at least one sensor (18). The at least two sensors (18) have a first sensitivity at which a first signal can be generated as a result of the sensor (18) being acted upon by a first parameter detectable by the sensor (18), and the respective illuminance can be set in a manner dependent on said first signal. Each of the at least two sensors (18) is adapted to generate an address, wherein the generated address of the respectively addressed sensor can be determined by the control unit (14). The at least two sensors (18) are adapted to have a second sensitivity, wherein the respectively addressed sensor (18) is designed to generate a second signal, which is detectable by the control unit (14), when the sensor (18) having said second sensitivity is acted upon by a second parameter detectable by the sensor (18).
