1. A method for automatically adjusting the lighting parameters of a space, wherein a plurality of smart lamp groups, a plurality of ambient light sensor modules, a control module, and an interface device are arranged in the space and are connected through a wireless communication protocol; the smart lamp group and the interface device are respectively paired to the ambient light sensor module and the control module through the wireless communication protocol; and the control module and interface device are connected to the cloud through the Artificial Intelligence of Things, the method comprising the following steps:
driving the smart lamp groups to illuminate in the space, wherein the ambient light sensor module drives the smart lamp groups to illuminate in the space by using the lighting parameters of the preset light recipe;
setting the target lighting parameters in the space, wherein the control module sets the equivalent melanopic illuminance (EML) and circadian action factor (CAF) of the human circadian rhythm according to the interval of the daily time, as the target lighting parameters in the space;
driving the ambient light sensor modules to perform an ambient light detection in the space by the control module and sending the ambient light detection value to the control module; and
determining if the ambient light detection value is the same as the value of the target lighting parameters, wherein the control module compares the ambient light detection value in the actual environment with the value of the target lighting parameters, wherein
when it is determined that the ambient light detection value is the same as the value of the target lighting parameters, the ambient light sensor module continues to drive the smart lamp groups to illuminate with the lighting parameters of the preset light recipe; and
when it is determined that the ambient light detection value is not the same as the value of the target lighting parameters, the control module drives the ambient light sensor module performs a dimming procedure to the smart lamp groups, wherein the dimming procedure comprising the following steps:
performing the dimming procedure according to the target lighting parameters by the ambient light sensor module, so that the value of the lighting parameter in the actual environment is the same as the value of the set target lighting parameters; and
adjusting an illuminance uniformity of the space according to the actual illuminance detected by the ambient light sensor module, after the calculation of the illuminance uniformity formula, the illuminance uniformity is adjusted to be the same as a target illuminance uniformity.
