step S112, calculating the lighting time length according to the opening time and the closing time;

and step S113, counting the lighting time of N days before the day.

Specifically, in step S211, a timer is provided in the lamp, and the timer is used for recording the on-time and the off-time of the lamp adaptive power supply, where the table 1 below shows the on-time and the off-time of the lamp adaptive power supply recorded by the timer:

TABLE 1

In step S112, the lamp calculates a difference between the two adjacent on-times and the two adjacent off-times according to the on-time and the off-time of the lamp adaptive power source recorded by the timer to obtain the lighting time duration, where the difference is calculated by calculating the difference between the on-time and the off-time of two adjacent days, instead of the difference between the on-time and the off-time of the same day, because the lamp is generally turned off in the morning and evening of the previous day.

In step S113, after the plurality of lighting time durations are obtained through the difference calculation, the different lighting time durations are counted, specifically, the lighting time durations N days before the counted day are counted, where N is an integer greater than 1 and less than 11, and for the specific value of N, reference may be made to the description of the above embodiment, which is not described herein again. In addition, data obviously deviating from the normal brightness duration is excluded during statistics, as shown in table 1, the lighting duration of the lamp in 11 days is 11 hours and 30 minutes, and the lighting durations before and after the day are between 9 hours and 30 minutes and 10 hours, so that the lighting duration of the lamp in 11 days is obviously beyond the normal lighting duration, the exclusion processing should be given during statistics, and the lighting duration of the data after the exclusion processing, which does not meet the requirement of N days, is generally selected to be filled.

In addition, referring to fig. 10, which is a flowchart of another method of the lighting control method according to the second embodiment of the present invention, step S120 matches an initial dimming program from the preset dimming programs of the lamp according to the statistical result, and specifically includes:

step S121, carrying out weighted average on the lighting time lengths of N days before the statistical day to obtain the average lighting time length;

and step S122, the plurality of dimming programs respectively correspond to standard lighting time intervals, and the initial dimming program is matched according to the standard lighting time interval in which the average lighting time is located.

Specifically, in step S121, the counted lighting durations of N days before the statistical day are weighted and averaged, and the obtained average value is the average lighting duration of N days before the statistical day, where it is to be noted that the statistical lighting duration obviously deviates from the normal duration value, an exclusion process is to be given, and if N lighting durations are not reached after exclusion, the previous normal duration value of the exclusion value is generally taken to supplement so as to ensure the accuracy of the obtained average lighting duration, as shown in table 2 below:

TABLE 2

In step S122, the plurality of dimming programs are stored in the memory of the lamp and respectively correspond to standard lighting time intervals, specifically, as shown in table 3 below, the standard lighting time intervals corresponding to a summer dimming program, a spring and autumn dimming program, and a winter dimming program are respectively given, after the average lighting time is obtained in step S310, the average lighting time is compared with the plurality of standard lighting time intervals, if the obtained average lighting time is 9:35, the corresponding standard lighting time interval can be obtained according to table 3 to be 9: 30-10: 30, then the dimming program corresponding to this time is the summer dimming program, that is, the summer dimming program is matched according to the standard lighting time interval where the average lighting time is located, and thus the summer dimming program is used as the initial dimming program.
