Abstract
An LED tube light includes a glass tube, a base, a light emitting unit, and two lateral cover assemblies. The base has a length larger than the length of the glass tube, wherein two opposite end portions of the base are arranged out of a region defined by orthographically projecting from the glass tube to the base. The light emitting unit is fixed on the base and is used for emitting light, passing through the glass tube to illuminate. The two lateral cover assemblies are respectively covered around the two end portions of the glass tube, wherein the two lateral cover assemblies are respectively installed on the two end portions of the base for maintaining the relative position between the cover assemblies and the base.
