Abstract
An optical disc unit for an ultraviolet sterilizer, which is applied to the ultraviolet sterilizer, includes an ultraviolet light emitting diode (LED) to reflect light irradiated from the ultraviolet LED, including a body portion including a hollow and a primary optical unit fixedly coupled to an internal diameter surface in the hollow of the body portion and disposed in a direction perpendicular to an emission surface of the ultraviolet LED to reflect light irradiated from the ultraviolet LED, and according to an exemplary embodiment of the present disclosure, it is possible to enhance a sterilization ability by increasing a beam angle of light irradiated from the ultraviolet LED and uniformly irradiating the light and also reduce a risk of light leakage to the outside in a space to which the ultraviolet LED is applied.
