ABSTRACT:
Fingernail light systems for curing photopolymerizable plastics on fingernails are known, having a housing with a bottom plate 7, in which housing a support body 4, having indentations 18 on its outer contour, is provided for positioning the fingers of the hand 5 to be irradiated, and having at least one irradiation lamp 14, which at least partially surrounds the support body in a spaced-apart manner in the irradiation position, the support body being accessible in the irradiation position via an opening 10 in the housing. In order to provide a system that meets the indicated needs and assures a uniform irradiation of all the fingernails of both the left and the right hand, with the light originating in the irradiation lamp substantially striking the fingernails (20-24) to be cured, in which fingernails of even great length can be irradiated and a comfortable hand posture can be maintained, even over a relatively long period on the order of half a minute, the support body 4 of the present invention features an approximately cylindrical (FIG. 1) or frusto-conical (FIG. 3 ) outer contour, at least in the vicinity of the indentations, and the indentations are in the form of channels 18 that extend substantially in the direction of the axis of the support body, and the axis 3 of the support body 4 forms an angle in the range from 0.degree. to 90.degree. with the direction 31 orthogonal to bottom plate 7.
