Abstract
The present invention relates to a fluorescent tube structure, which fluoresces when connecting electric power, including a base plate and an upper cover forming a enclosed discharge chamber, wherein pellicles applied inside to enable an illuminant to project to the curved surface of the upper cover and then be reflected to the base plate, which enhances illumination and also reduces illumination loss to the lateral, thereby improving illuminant efficiency. The present invention can be used as a backlight on illuminating and electronic display devices.
Claims8
