This invention discloses a multi-source coordinated light-emitting combined lighting system, relating to the field of combined lighting technology. It includes a temperature sensor array, a spectral-colorimetric sensor, and a controller. The temperature sensor array collects temperature values ​​at multiple preset locations within the light source array to obtain temperature distribution data. The spectral-colorimetric sensor collects color parameters from at least two different regions of the emitted light spot from the light source array to obtain spatial color difference data. This invention addresses the root cause of the thermal field morphology by actively "flattening" the thermal field curvature, effectively suppressing the spatial colorimetric degradation of the light spot caused by the central heat island effect. This significantly improves the spatial consistency of the combined lighting system under long-term high-power operation, while also adapting to individual differences in different lamps and long-term aging drift, fundamentally eliminating the spatial color difference problem caused by uneven thermal field distribution.
