An LED light module comprises an emitting portion; at least one LED package; a back cover; and an end cap. The emitting portion defines a first curved surface. The first curved surface extends a first length along a cylindrical axis defined by the LED light module. The back cover defines a second curved surface extending the first length along the cylindrical axis. The first curved surface and the second curved surface define a perimeter of the LED light module. In a cross-section of the LED light module taken in a plane substantially perpendicular to the cylindrical axis, the perimeter is substantially ovular, elliptical and/or tear-drop shaped. The end cap is substantially ovular, elliptical and/or tear-drop shaped, and comprises a coupling element configured to electrically and/or mechanically couple the LED light module to a subsequent LED light module or to a fixture.

An LED tube lamp includes a lamp tube, an LED module, a power supply module, a micro switch, and an actuator. The lamp tube has pins for receiving an external driving signal. The power supply module is configured for supplying power to the LED module. The micro switch is coupled to the power supply module. And the actuator is configured to cause the micro switch to change to a closed-circuit position to allow the power supply module to supply power to the LED module for emitting light. When the LED tube lamp is properly installed into a lamp holder, the micro switch closes to electrically connect the power supply module to an external driving signal.

A light tube with wire guide includes a hollowed tube body, two caps, a wire guide, and a plurality of wires. The two caps respectively cover two ends of the hollowed tube body. The wire guide is located at an outer side wall of one of the two caps. The wire guide includes a guiding slot communicating with the hollowed tube body. The wires are disposed in the wire guide and extended along the guiding slot. One ends of the wires are located in the hollowed tube body or located in one of the two caps, and the other ends of the wires extend to the guiding slot and are exposed out of the hollowed tube body.

An alignment system for a linear light fixture includes multiple light elements. Each light element includes a top surface that defines a top channel. Each light element includes an endcap that defines apertures that extend through an entire thickness of the endcap. A top surface of each endcap defines an endcap channel. A hanger insert is positionable between the endcaps of two light elements. The hanger insert defines additional apertures. A top surface of the hanger insert defines an insert channel and a hanger connection. The top channels, the endcap channels, and the insert channel form an elongate channel. The system includes pins that are configured to extend through the apertures of the endcaps and the hanger insert. The system includes a connector plate that is configured to be received and secured within the elongate channel. The connector plate defines a central aperture that provides access to the hanger connection.

A rotary lamp cap, includes a casing element, a rotary loop, and a side end cover. The casing element and the side end cover are respectively sleeved on a groove at each side of the rotary loop. When the rotary loop moves away from the casing element, the rotary loop and the casing element change from the original buckled state to the disengaged state. An outside end face of the side end cover includes a flat area and two plug-in holes, the flat area is located outside the plug-in holes, and two conductive poles are respectively plugged in the plug-in holes. No other holes except for the plug-in holes are provided on the end face of the side end cover, thereby enabling the side end cover to have locking function with no air hole.

A stacked pipe light emitting diode lighting fixture with uniform and uninterrupted emitted light is disclosed. The stacked pipe light emitting diode lighting fixture comprises a plurality of transparent light pipes disposed in a housing. A light emitting diode module is connected to a light receiving end of each light pipe. The light pipes and connected light emitting diode modules are positioned so that light reflecting ends of the light pipes overlap the light emitting diode modules. As a result, the emitted light is uniform in intensity and uninterrupted for one end of the stacked pipe light emitting diode lighting fixture to the other end of the stacked pipe light emitting diode lighting fixture.
