Abstract
A sterilization device has an ultraviolet light unit including an ultraviolet light source and a filter for filtering wavelengths of 230 to 270 nm, emitted from the ultraviolet light source; a lighting unit including an LED light source; and a control unit which controls on and off of the ultraviolet light unit and the lighting unit and supplies power, wherein the filter includes a nanophosphor which is 3 nm or less and converts the light having a wavelength of 230 to 270 nm into light of another wavelength.
Claims10
A sterilization lamp comprising:
- an ultraviolet light unit including an ultraviolet light source and a filter for filtering wavelengths of 230 to 270 nm, emitted from the ultraviolet light source;
- a lighting unit including an LED light source;
- and
- a control unit which controls on and off of the ultraviolet light unit and the lighting unit and supplies power,
- wherein the filter includes a nanophosphor which is 3 nm or less, and the nanophosphor converts the light having wavelengths of 230 to 270 nm into light of another wavelength.

A sterilization lamp comprising:
- a planar lamp in which at least one or more light sources emitting 222 nm ultraviolet rays are disposed at an inner region;
- a filter being coated or laminated on a light-exiting surface of the lamp to filter light having a wavelengths of 230 to 270 nm;
- and
- a power supply unit supplying power to the lamp,
- wherein the filter includes a nanophosphor having a size of 3 nm or less to convert light having a wavelengths of 230 nm to 270 nm into a light having a different wavelength.
