Abstract:
An optical exposure device, for hardening light-hardening gel in the course of finger nail treatment, comprising:a light source housing; a light source plane disposed horizontally across said light source housing; at least two U-shaped light sources disposed in said light source housing and arranged in a V-shaped fashion in said light source plane and tilted toward one another with respect to said light source plane; and a bearing surface disposed horizontally parallel below said at least two UV light sources and said light source plane and having a convex surface for a hand with the finger nails to be treated; wherein the angle of inclination of said at least two light sources has a value between 30Â° and 60Â°; and wherein said at least two U-shaped light sources are tilted so that the UV rays are directed toward said bearing surface maximizing the intensity at said bearing surface.
