[0002] Indoor lighting has a significant potential impact on human health. The design of the indoor lighting environment not only influences occupants' ability to perform visual tasks but also impacts their comfort, mood, and other physiological functions. The temporal distribution of human exposure to the light environment also influences a range of other important physiological functions, including metabolism and sleep quality. Therefore, accurately and comprehensively quantifying the indoor light environment, including both natural and artificial lighting, is crucial. Currently, a key method for quantifying indoor light environments in the lighting field is the circadian effect, and the lighting system developed based on this quantification method is known as circadian lighting.

[0076] The daytime M / P ratio is ≥ 0.9, specifically 0.9 to 1.27, exemplified by, but not limited to, 0.92, 0.95, 0.97, 0.99, 1.03, 1.08, 1.14, 1.19, 1.23, or 1.26, preferably 0.93 to 1.27, and more preferably 1.11 to 1.27.

[0085] The M / P ratio obtained during this nighttime period is low, and the level of rhythmic stimulation is low, which can promote the secretion of melatonin in the human body, making people feel relaxed and sleepy, thereby improving the quality of rest and sleep.

Preferably, the light output ratio of the first light source is 3.1% to 45.8%, the light output ratio of the second light source is 0.3% to 9.5%, the light output ratio of the third light source is 11.9% to 18.2%, the light output ratio of the fourth light source is 0% to 0.7%, and the light output ratio of the fourth light source is 35.8% to 75%.

[0087] It should be noted that there is no necessary order between step S201 and step S202, and they can be performed according to actual time periods.

[0088] Based on the control method of the above embodiment, the light output ratio of each light source in the five-channel rhythmic lighting fixture can be adjusted in different time periods to meet the lighting needs during the day and at night.

[0093] Based on the above control method, not only the M / P ratio, color rendering index, and spectral radiant efficiency are adjusted, but also the color temperature is adjusted. This can further optimize not only the rhythmic stimulation level but also the spectral radiant efficiency.

[0094] It should be noted that there is no necessary order between step S301 and step S302, and step S302 can be performed while step S301 is being performed.
