According to the light illumination value and the known value of artificial light emitted by the LED lamp beads, the current natural light value can be obtained through a simple subtraction operation. The same natural light conditions must be maintained during the simulation calculation.

[0057] The Osprey optimization algorithm is used to converge the iterative population of the lighting illumination adjustment strategy. When the maximum number of iterations is reached, the lighting illumination adjustment strategy individual H corresponding to the maximum fitness is output. i , which is the optimal lighting illumination adjustment strategy individual; the parameters used to adjust the light effect of the non-fluorescent LED lamp beads in the optimal lighting illumination adjustment strategy individual are used as the real-time lighting illumination adjustment strategy.
