Referring to FIG. 13 , a pair of side parts 113 of the housing 100 may be disposed to face both side surfaces 30b of the handrail. The side case 520 of the case 500 surrounding the side portion 113 of the housing 100 may also be disposed to face both side surfaces 30b of the handrail. The fourth reflector 521a and the fifth reflector 521b may be coupled to the side case 520 by a fastening member such as a bolt, and the fastening part 313 faces both side surfaces 30b of the handrail, respectively. It may be disposed at both ends of the Y-axis direction.

The fourth reflector 521a and the fifth reflector 521b may reflect some of the light emitted from the UV light emitting device 330 and radiate it to both side surfaces 30b of the handrail.

The fourth reflector 521a and the fifth reflector 521b may be spaced apart from each other in the Y-axis direction, and the distance D2 between the fourth reflector 521a and the fifth reflector 521b is the first circuit board ( 320), it may decrease. By this configuration, even if a light source is not additionally disposed on the side surface 30b of the handrail, a part of the light irradiated from the UV light emitting device 330 is reflected from the fourth reflector 521a and the fifth reflector 521b, thereby increasing the light intensity of the handrail. The side surface 30b may be irradiated. The fourth reflector 521a and the fifth reflector 521b may have the same or different curvatures.

Although the above has been described with reference to the embodiments, these are merely examples and do not limit the present invention, and those skilled in the art to which the present invention belongs will not deviate from the essential characteristics of the present embodiment. It will be appreciated that various variations and applications are possible. For example, each component specifically shown in the embodiment can be modified and implemented. And differences related to these variations and applications should be construed as being included in the scope of the present invention as defined in the appended claims.
