Abstract: A light tube having rotatable end caps includes a tube body, two positioning connectors and two rotatable end caps. The two positioning connectors are disposed at the two ends of the tube body respectively. Each of the positioning connectors includes a base and a cylindrical body disposed on the base. The base is provided with a waved positioning structure between the outer edge of the base and the outer surface of the cylindrical body. The two rotatable end caps are disposed at the two positioning connectors respectively. Each of the rotational end caps is rotatably connected to the cylindrical body of the positioning connector corresponding thereto. Each of the rotatable end caps has an elastic element corresponding to the waved positioning structure and engaged with the wave structure.

Abstract: A lighting device includes a suspension structure and a light tube. The suspension structure includes a flat plate member, a clamp member, and a fixing member. The flat plate member has a first hole disposed at one end of the flat plate member. The clamp member is disposed on one side of the flat plate member, and includes a main body and two wing portions respectively disposed at two ends of the main body. The main body has a rotation hole, and each of the wing portions has a bent portion. The fixing member passes through the rotation hole and the first hole, such that the clamp member is rotatably fixed to the flat plate member. The light tube includes a tube body having two grooves. The bent portions of the wing portions are embedded in the grooves respectively.

Abstract: A luminaire with seamless splicing function includes a first lamp body and an end cap. The first lamp body has two joining portions disposed at the two sides thereof respectively. The end cap is combined with one of the joining portions and is a streamlined structure. The end cap has a curved side tip, a curved bottom tip and two side walls. The two sides walls are disposed at the two sides of the curved side tip and extend to the curved bottom tip. The two side walls are curved, and the curved side tip, the curved bottom tip and the two side walls are integrally formed. The streamlined structure of the end cap makes the shape thereof smooth in order to facilitate the smooth flow of air in cleanrooms and eliminate dust.
