Abstract

The present invention is related to an UV curing apparatus, and more particularly, to an UV CCFL curing apparatus utilizing UV CCFL as light source. In order to provide an curing apparatus capable of generating UV light of high intensity and uniform lighting with great electrical safety and reliability, the UV CCFL curing apparatus of the present invention comprises a detachable UV CCFL light source that is designed and built to operate at high voltage, in a range greater than or equal to one thousand volts, with dielectric plugs and installation guides, and it may preferably include a light-transmissive protective cover to further protect users from direct contact with the UV CCFL light source during the curing operation in the curing chamber of the apparatus and to offer as a further protection to the fragileness of the UV CCFL thin glass tubes, which may too further filter certain wavelength of the UV light, such UVC. The UV CCFL curing apparatus of the present invention is preferably provided for curing UV hardening gel applied onto the nails of multiple fingers or toes all at once. Furthermore, the outer casing of the apparatus is detachably attached to the inner casing to allow a greater user interaction for decorative and entertainment purposes in addition to its protection to the apparatus as a whole.
