Abstract: A modularized lighting device includes a lighting module and a frame. The lighting module includes a housing and two end caps disposed at the two ends of the housing respectively. Each of the end caps includes a base having an accommodating space and two connecting sheets fixed at the bottom of the accommodating space. The frame includes two electrical connecting modules. Each of the electrical connecting modules includes an installation base having an installation space and two clamping structures disposed at the bottom of the installation space. The two end caps are detachably installed at the two electrical connecting modules respectively, such that the two connecting sheets of each of the end caps are inserted into the two clamping structures of the electrical connecting module corresponding thereto.

Abstract: A lamp tube structure capable of preventing glue from overflowing includes a hollow tube body and a cap body. The cap body covers the opening of the hollow tube body. The inner surface of the cap body has a plurality of ring-shaped protrusion portions arranged to be parallel with each other. The glue is distributed over the inner surface of the cap body and the protrusion portions can prevent the glue from overflowing. The outer surface of the hollow tube body contacts the protrusion portions. The protrusion portions inside the cap body can avoid that the glue overflows from the gap between the cap body and the hollow tube body in order to improve tightness. Thus, the contact area between the glue and the inner wall of the cap body can increase, so the cap body and the hollow tube body can be firmly fixed with each other.

Abstract: A first lamp tube includes a first lamp housing, a plurality of first light-emitting elements disposed within the first lamp housing, a first lamp head connected to the first lamp housing, and a color temperature switch module disposed on the first lamp head. A second lamp tube includes a second lamp housing, a plurality of second light-emitting elements disposed within the second lamp housing, a second lamp head connected to the second lamp housing, and a power adjustment terminal disposed on the second lamp head configured to be connected to an external power adjustment device. A coupling assembly is disposed between the first lamp housing and the second lamp housing to fix the first lamp housing to the second lamp housing, and electrically connect the first lamp tube to the second lamp tube.

Abstract: A lamp socket of a color temperature adjustable lamp tube includes a housing and a color temperature adjustment member. The color temperature adjustment member is disposed on the housing and is connected to a plurality of light emitting members corresponding to two or more color temperatures. The color temperature adjustment member is provided for switching the light emitting members to change the color temperature of a light.
