    摘要： A light emitting diode (LED) tube supporting dimming by a low voltage dimmer for replacing a conventional fluorescent lamp is disclosed. The LED tube comprises a tube body, two end caps, four pins, as well as a dimmable LED driver and one or more LEDs in the tube body wherein the LEDs are connected to the dimmable LED driver and driven by the dimmable LED driver. Two of the four pins are used for receiving power input from an AC power supply, and the other two of the four pins are used for receiving dimming control signals from a low-voltage dimmer. The tube body is a hollow cylindrical tube with the same mechanical structure of a conventional fluorescent lamp.

    摘要： LED light tubes are described herein which have rotatable end caps. The LED light tubes have a hollow tube, a circuit board with LED chips thereon installed on the hollow tube, and rotatable end cap assemblies on either end of the tube, wherein each rotatable end cap assembly includes a socket cap, a plug having a plug body and at least one connector, a rotatable end cap having an end cap body one end of which engages one of the ends of the hollow tube and the other end of which has a surface defining a recess, at least one bore extending through the rotatable end cap defining a passageway, and a collar situated between the inner surface of the rotatable end cap and the longitudinally extending bore. The plug body is received at least partially within one end of the rotatable end cap. The rotatable end cap assembly also includes a cam locking mount that is positioned within the plug body and on the opposite side has projections to be positioned in the bore of the rotatable end cap forming an opening therebetween in general alignment with the bore of the rotatable end cap. A rotation cam is positioned in the recess of the rotatable end cap to engage the collar and is also seated in the cam locking mount. The rotatable end cap provides controlled rotation on the LED tube. Methods of installing the LED light tubes in new installations and retrofit installations and for use in sign assemblies are also described.
