An innovated type of luminescent cover unit for lighting unit, applicable to a variety of lighting fixtures (such as a lamp tube or a light bulb), made of flexible, elastic, environmentally-friendly, see-through materials, in combination with long-lasting luminescent materials in the shape of a cylinder, a C figure or a bag that is either colored and translucent or uncolored and transparent. The cover unit envelops or wraps the lighting unit for regular lighting purposes at normal hours; the cover unit made to have a colored and translucent surface functions to change the color of light projected from the lighting unit to create a different atmosphere; the cover unit continuously absorbs and stores the luminous energy projected by the lighting unit at normal hours, and give luminescent light during nighttime or in case of power failure, thereby achieving the purposes of free change of use and cost savings.
