  • Electric shock insecticidal device
    Patent number: 10271536
    Abstract: The present invention provides an electric shock insecticidal device reducing noise and light pollution emitted to an outside. The electric shock insecticidal device converts output voltage and output current supplied to a grid electrode into AC voltage and AC current or into DC voltage and DC current selectively; controls levels of the converted output voltage and current; adjusts an amount of light of the ultraviolet lamp emitted to an outside by using a light blocking layer or an adjusting unit adjusting illumination of an ultraviolet lamp; and easily separates the grid electrode having high voltage from a body unit to remove electrocuted flying insects from the grid electrode.
