Abstract (en)
[origin: GB2300254A] A lighting system comprises a multiplicity of luminaires (A1 to A4, B1 to B4, C1 to C4 and D1 to D4) and a central control unit 1 for controlling the light outputs of the luminaires. The luminaires are divided into a plurality of groups, each arranged to receive its own control signal from the central control unit and having a respective local control means (7, 8) which is arranged to control the light outputs of individual luminaires of the group in dependence upon both a signal from the central control unit 1 and information stored in the local control means (7, 8).
