Abstract
A lighting control method includes steps of: obtaining an influence range of lighting irradiation of a light source; recognizing a plurality of designated targets within a certain range; making a marking for each of the designated targets and obtaining a current distance between each of the designated targets and the light source; obtaining a current output power of the light source; and determining whether the marking enters the influence range, whether the current distance is less than a preset distance threshold, and whether the output power is greater than a preset power threshold, if all yes, outputting a protection signal. According to the present invention, safety can be visually and quickly determined in an easy way through three conditions including the influence range, the current distance and the output power, without complex energy density calculation.
