<P>PROBLEM TO BE SOLVED: To provide an end cap structure of an LED tube with sufficient strength secured. <P>SOLUTION: The lamp tube structure has a first end cap 110, a second end cap 120, a heat sink support part 130, a light-emitting element array 140, and a lamp cover 150. The first end cap has a pair of electric terminals 112a, 112b and a first insulating part 111. The electric terminals are incorporated in the first insulating part by insert molding, and one end of each electric terminal projects from an outside of the first insulating part. The second end cap has a grounding terminal and a second insulating part. The grounding terminal is incorporated in the second insulating part by insert molding, and one end of the grounding terminal projects from the outside of the second insulating part. The light-emitting element array is arranged at an upper face of the heat sink retention part. A bottom face of the lamp cover is fixed to the heat sink retention part for receiving the light-emitting element array. <P>COPYRIGHT: (C)2012,JPO&INPIT |
