The present invention relates to an UV LED lamp and, more specifically, to a lamp converting UV LED light of a point light source into that of a surface light source and emitting the surface light source with the simplest structure. The UV LED lamp of the present invention: enables the higher refraction and diffusion of UV light entering through the inner surface of a cover by respectively roughening the inner surface and the outer surface of PMMA or quartz forming the cover; allows the refraction and diffusion again when the UV light, which has been entered through the inner surface of the cover, is emitted to the outside through the outer surface of the cover; and thus enables UV light of the point light source to be completely converted into that of a surface light source. Further, the UV LED lamp of the present invention enhances the transmissivity of the UV light by allowing reflectivity occurring on the outer surface of the cover to be smaller than reflectivity occurring on the inner surface of the cover so as to reduce reflection of the UV light, which is emitted through the outer surface of the cover, on the outer surface; and converts UV light of the point light source into UV light of the surface light source while reducing the loss of UV light caused by the conversion by enhancing the re-reflection of the UV light, which has been reflected from the outer surface of the cover, on the inner surface of the cover so as to enable the UV light to return to the inside of the lamp, not to be lost, and re-enter toward the outer surface of the cover. |
