Background With the development of intelligent lighting technology, lamp cluster cooperative control is widely applied to large indoor spaces (such as office buildings, markets, factory workshops and the like). The existing lamp cluster control method adopts an independent area control strategy, namely, lamps in each illumination area are only adjusted according to the illumination requirement of the area, and the illumination superposition effect generated by illumination of lamps in the adjacent illumination areas is ignored. In practical applications, because the light of the lamps can be diffused to adjacent areas, the lamps of multiple illumination areas can generate overlapping illumination for the same target area. The existing independent control mode causes that each area lamp performs power adjustment under the condition that the illumination contribution of the adjacent areas is not known, so that the actual illumination intensity of the target area exceeds the demand, and unnecessary energy waste is generated. Meanwhile, due to the lack of a cooperative scheduling mechanism among areas, the optimal configuration of the whole energy consumption of the lamp cluster cannot be realized.
