The invention discloses a small night lamp control circuit. The small night lamp control circuit firstly detects that a current environment is daytime or night through a photosensitive sensor and detects whether a human body goes by or not through an infrared sensor, when a detection result is night and the human body goes by, a controller outputs a PWM signal with the gradually-increasing duty ratio to drive a brightness control circuit, and the brightness control circuit controls LED lamps to be gradually turned on. In a similar way, when the infrared sensor senses that the human body does not exist, the controller outputs a PWM signal with the gradually-decreasing duty ratio to drive the brightness control circuit, and the brightness control circuit controls the LED lamps to be gradually turned off. By means of the small night lamp control circuit, adaption to a surrounding environment of eyes is facilitated by controlling gradual turning-on and turning-off of the LED lamps, lamp light stimulation on the eyes is alleviated, and secondary sleep of people get up at night is facilitated.
Description
technical field [0001] The invention relates to the technical field of lighting, in particular to a small night light control circuit. Background technique [0002] The light of the night light is soft and plays the role of guiding lighting in the dark. People wake up in the middle of the night to do things, and a small night light brings us great convenience. However, the following deficiencies are common in traditional night lights: after the induction is powered on, the night lights will light up instantly, and when getting up at night, everyone is often in a half-sleeping state, and the instantaneous change from dark to bright is very irritating to the eyes and affects the eyes. Human's second sleep. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to provide a night light control circuit, which can control the night light to slowly turn on and off when it senses that someone is passing by at night, wh...
