METHOD OF RECYCLING FLUORESCENT SUBSTANCE FOR FLUORESCENT LAMP, RECYCLED FLUORESCENT LAMP AND LIGHTING APPARATUS USING THEREOF

摘要

PURPOSE: Provided are a method of recycling fluorescent substance for fluorescent lamp, a recycled fluorescent lamp, and a lighting apparatus using thereof. CONSTITUTION: The fluorescent substance material and the glass material are individually recovered by classifying the recovered fluorescent lamps according to a kind or quality and by stripping off the fluorescent substance coating from the inner surface of the glass bulbs. The recovered fluorescent substance material and the glass material are regenerated and reused. In the process for regenerating the recovered fluorescent substance, mercury involved in the recovered fluorescent substance is removed, for example, by firing the recovered fluorescent substance in a vacuum, in an inert atmosphere. The recovered glass material is also subjected to the process for removing mercury.
