ABSTRACT:
A handheld or display assembly device which allows a user to obtain UV light in varying wavelengths from a single standard short-wave (SW) ultraviolet lamp. A standard SW ultraviolet lamp that has no phosphor coating is used, and the conversion sheets with different mixtures (or compounds) of phosphor are applied to convert the SW light into a medium-wave or long-wave light. One aspect of the present invention comprises an ultraviolet lamp, a housing for said lamp, a set of conversion sheets, and holding elements for removably mounting the conversion sheets adjacent the lamp. Another embodiment comprises a continuous sheet of the conversion sheets which is configured to roll across the front of the UV lamp, thereby converting the SW light into medium-wave or long-wave light.
