Children sleep guarding lamp and adjusting method thereof

Abstract

The invention discloses a children sleep guarding lamp. The children sleep guarding lamp includes an infrared thermopile sensor, an LED luminescence module, a color temperature selection circuit, a constant current light modulation circuit, a PWM shaping filter circuit, a main control chip, and a voltage conversion circuit, wherein the infrared thermopile sensor is used for measuring the heat source information in a room; the LED luminescence module includes an LED light source which is used for providing a light source for daily activities of children; the color temperature selection circuit switches various color temperatures among the lighting color temperatures of the LED luminescence module according to the active state of children; the constant current light modulation circuit outputs PWM waveforms with different duty ratio; the PWM shaping filter circuit filters the PWM waveforms output from the constant current light modulation circuit; the main control chip controls the color temperature selection circuit to switch different color temperatures according to the active state of children, and controls the constant current light modulation circuit to output the PWM waveforms with different duty ratio to change the luminance of the LED luminescence module; and the voltage conversion circuit converts the voltage values of the waveforms output from the constant current light modulation circuit. The children sleep guarding lamp can solve the technical problem that in the prior art, parents have to turn off the sleep lamp after children fall asleep, and the luminance and color temperature of the sleep lamp cannot be adjusted according to the active state of children.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a children's sleep guard lamp and an adjustment method. Background technique [0002] Children lack a sense of security when falling asleep, and need a certain amount of light in the environment to fall asleep safely. The light intensity should be soft enough, neither too strong nor too weak. After the child falls asleep, if the light continues to be on, it will affect the child's sleep quality, which is very detrimental to the healthy growth of the child. Now the common practice of parents is to turn on the light in the room when the child falls asleep, and then turn off the light in the room after the child falls asleep. to further adjust the brightness and color temperature of the light. Chinese patent CN204328628U discloses a sleep light, which includes a wristband that can be bound to the user's wrist. The wristband is provided with a pulse monitor and a wireless transmission module. ...
