The invention relates to the technical field of smart home, in particular to a multi-sensor fusion adaptive dimming and color modulation system for smart home and a control method, and the system comprises a distributed illumination array which comprises a plurality of illumination partitions and an edge calculation controller, an illuminance sensor, a spectrum sensor, a power supply ripple monitor, a junction temperature sensor, an intelligent dimming driving module and a thermal management module which are in communication connection with the edge computing controller are arranged in each lighting subarea, and the lighting subareas comprise a first lighting subarea and a second lighting subarea which are physically adjacent to each other. The photoelectric thermal coupling unbalance state of the illumination partition can be accurately identified by monitoring multiple items of data such as illumination, spectral distribution, power supply ripple and junction temperature in real time, and the dimming process can be optimized and the overall lighting effect of the system can be improved through a cooperative regulation and control strategy based on an electrical connection topological relation and ripple propagation time sequence characteristics.
