The invention discloses a multi-mode light-supplementing sleep-aiding
control circuit, device and
system integrating sound, light and smell, and a control method, and relates to the technical field of electronic circuits. The circuit comprises a main control module, a light supplementing module, a sleep-aiding lamplight module, an environment sensing module, an
aromatherapy module, a power
amplifier loudspeaker module and the like, low-blue-light soft and brightness-adjustable illumination is output through the light supplementing module, and the problems of too strong
blue light, screen stroboflash and reading fatigue when an intelligent terminal is used are solved. The sleep-aiding light module can be adjusted to warm
color temperature, the
mood is relaxed, and illumination secreted by
melatonin is not damaged. The environment sensing module collects environment light and proximity distance information in real time, so that the equipment can intelligently adjust the light supplementing brightness and the sleep-aiding lamp mode; hot
fumigation closed-
loop control is adopted for the
aromatherapy module, constant-temperature adjustment is achieved through temperature sampling, and volatilization of sleep-aiding fragrance is more stable and
safer; the power
amplifier loudspeaker module provides stable output for
white noise, natural sound and rhythmic
respiration guiding sound, and provides reliable acoustic assistance for sleep adjustment.
