A lamp tube structure includes a first end cap, a second end cap, a heat sink holder, a light emitting element array and a lamp cover. The first end cap includes a pair of electrical terminals and a first insulating portion. The electrical terminals are integrated into the first insulating portion by insert molding, and one end of each electrical terminal is protruded from an outside of the first insulating portion. The second end cap includes a grounding terminal and a second insulating portion. The grounding terminal is integrated into the second insulating portion by insert molding, and one end of the grounding terminal is protruded from an outside of the second insulating portion. The light emitting element array is disposed on top surface of the heat sink holder. A bottom surface of the lamp cover is fixed on the heat sink holder for receiving the light emitting element array.

Lamp tube structure and assembly thereof

A cover and a lamp structure. The cover whose curvature has a light incident surface and a light outgoing surface, and includes a plurality of 3D micro-structures disposed thereon and arranged in the form of an array. When a light is emitted into the light outgoing surface from the light incident surface, the light emitting angle of the light outgoing surface is increased through the refraction of the 3D micro-structures, so that the occurrence of mura or spots due to uneven distribution of the light is avoid.
