In order to set the time period more precisely and adjust the time period according to the change of seasons to generate the light intensity control signal more scientifically and control the lighting of the lighting fixture, in this embodiment, by taking the turning point of the time series trend of the light intensity data as a feature point, the change trend of the time series value of the light intensity during the decline process is studied, so as to obtain the change rate of the light intensity decline from dusk to complete darkness, and then calculate the time period T r , and adjust the time period T accordingly r , the change rate of the light intensity decline is represented by the slope, and its calculation formula is:

[0083]

[0084] In the above formula, t α represents the moment when the light intensity starts from the moment T when the first light intensity control signal is generated 1 to the moment when the light intensity time series is first determined to be in a descending segment, and t β represents the end moment of the light intensity decrease, that is, at this moment the light intensity no longer decreases and the sky is completely dark; g α1 represents the light intensity in the descending segment at the moment T 1 to the moment t α between the slopes; it α represents the timing value corresponding to the moment t α and it β represents the timing value corresponding to the moment t αβ and i is a preset time series period value; μ is a preset weight value; R represents the ratio of the light intensity decrease rate before and after the moment t α and can reflect the change of the light intensity decrease rate in the later stage of the descending segment relative to the decrease rate in the early stage of the descending segment; when the value of R suddenly increases, it means that the light intensity has dropped sharply, and the moment t α can be used as a turning point, and the result of t α -T 1 is used as the time period T r and as t α changes in value, the value of the time period T r is adjusted in a timely manner.
