ABSTRACT:
An LED lighting tube having a first segment, a second segment, and a rotating connector between the segments. Each segment has an elongated cylindrical housing, an aperture in the sidewall of the cylindrical housing, a reflector centered within the aperture, a circuit board within the cylindrical housing, and a rotatable electrical coupling connected to an outer end of the cylindrical housing. The circuit board has an LED that aligns with the aperture. The rotatable electrical coupling has a limiter insert that provides a rotative stop, a collet that at least partially surrounds the limiter insert and is rotatable about the limiter insert, and an interface connector secured to the limiter insert and in electrical communication with the circuit board. The rotatable electrical coupling permits the LED lighting tube to connect to a light fixture while also permitting the cylindrical housing to rotate relative to the light fixture. The rotation of the collet about the limiter insert is limited by the rotative stop.
