Abstract
In a light irradiation apparatus, an elongated body has flexibility that allows for elastic restoration. An LED chip is closely fixed to a tip portion of the elongated body and emits ultraviolet light. A cover unit covers the LED chip so as to protect the LED chip and allows the ultraviolet light emitted by the LED chip to pass through the cover unit. A conductive unit extends in a longitudinal direction of the elongated body and passes electric current for allowing the LED chip to emit light. An insulation unit covers the conductive unit so as to ensure electrical insulation of the conductive unit.
Claims12
A light irradiation apparatus comprising:
- an elongated body that is linear shaped member that is long in one direction and that has flexibility that allows for elastic restoration;
- a light emitting diode (LED) chip that is closely fixed to a tip portion of the elongated body and that emits ultraviolet light;
- and
- a cover unit that is formed of a material that covers the LED chip so as to protect the LED chip and allows the ultraviolet light emitted by the LED chip to pass therethrough,
- wherein the elongated body has:
- a conductive unit that extends in a longitudinal direction of the elongated body and that passes electric current for allowing the LED chip to emit light;
- and
- an insulation unit that covers the conductive unit so as to ensure electrical insulation of the conductive unit, and
- wherein the light irradiation apparatus is used for disinfection treatment of an object by allowing the LED chip to emit light while the elongated body is inserted into a narrow part.
