A magnetically-coupled resonant wireless night light circuit comprises a power transmitting module and a power receiving module. When the circuit is used, a base chip serves as a control chip, and power is supplied to an LED light by adopting a wireless power transmission mode by reasonably arranging an inductive coil on the basis of the electromagnetic induction principle; the outside illumination intensity can be sensed by a photoresistor, the transmitting power of the power transmitting end is automatically adjusted, and therefore intelligent light adjusting is achieved; repeated power supply insertion and extraction are avoided by means of wireless power transmission, therefore, the electricity safety is improved, and the service life is prolonged; and in addition, the circuit is simple in structure, convenient to use and low in circuit cost and has the good practical application value and application prospect.
Description
technical field [0001] The invention relates to a magnetic coupling resonance type wireless night light circuit. Background technique [0002] Night lights are commonly used electrical equipment, and are widely used in bedrooms, especially in families with infants, so that people can get up at night. At present, night lights are generally powered by in-line adapters and dry batteries. Among them, the direct plug-in night light needs to be plugged into the indoor 220V socket, and infants and young children will have a certain curiosity about the night light, so there is a certain potential safety hazard in electricity use, and repeated wiping and unplugging will also affect the night light. The lifespan of the light; dry battery-powered night lights require frequent battery replacements and are not conducive to environmental protection. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a magnetic coupling res...
