One embodiment of the invention relates to a light tower. The light tower includes a base, an extendible mast coupled to the base, a light assembly coupled to the extendible mast and electrically coupled to the battery pack, and an inverter configured to receive and convert a direct current power from the battery pack into an alternating current power. The extendible mast is configured to move between a lowered position and a raised position.

A lighting device includes a base assembly provided therein with a circuit board; a telescopic assembly provided with a fixed end and a free end that are arranged oppositely, where the fixed end is connected to the base assembly; and a lighting assembly rotatably connected to the free end to rotate axially and radially along the free end, where the lighting assembly is provided with a lighting element electrically connected to the circuit board. The lighting device realizes the extension and retraction of the lighting assembly and the lighting element through the telescopic assembly, such that the height adjustment of the lighting device can be realized in a large range, which is convenient for storage and carrying. In addition, in the lighting device, the lighting assembly and the free end are movably connected, such that the lighting assembly is rotatable axially and radially along the free end.

The present disclosure is directed to a stern light for illuminating a watercraft without visually impairing a passenger of the watercraft. The stern light includes a flexible pole with a hollow interior for housing wires. The wires are connected to a watercraft at one end of the pole and to a light source at another end of the pole. The light source, which may be an LED light source, is covered by a globe that at least partially refracts light. When powered, the stern light produces light capable of providing visibility of the watercraft for at least two nautical miles while also avoiding the visual impairment of watercraft passengers. Pole flexibility allows operation of the stern light during watercraft motion and in areas with potential obstructions, such as low-hanging branches.

Apparatus and methods for deployment of fixtures. The apparatus may include a system for controlling deployed fixtures. The system may receive user commands different devices in different formats. The fixtures may be independently addressable. The fixtures may be magnetically supported by a fixture support. A brace may join two or more fixture supports without reducing space available to support fixtures. The brace may join a fixture support to a fixture support accessory. An accessory may include a variable-angle junction. The fixture may include articulating joints for controlling the direction of a beam. The fixture may include a lens having an electrically controllable beam spread angle. The fixture may be stowable in the fixture support. The fixture may be slidable along a cord to adjust a height of the fixture. The fixture may include an extendable ring. The system may coordinate motions of the fixtures to follow a target. The fixture may include an elongated board. The elongated board may include a non-polar power socket.

A utility vehicle for power emergency repair includes a cab, a carriage and a lighting device, including mounting bases, a wire pole, a rotary base and a lamp assembly. A rotary shaft is bridged between the mounting bases, and the rotary base is fixedly connected to the rotary shaft. First and second positioning units are provided on the top of the carriage. The rotary base has first and second positioning surfaces, the first positioning unit includes a first limiting platform, and the second positioning unit includes a rotation limiting plate and positioning plates. The positioning plates is supported on a lower end surface of the rotation limiting plate. The utility vehicle further includes a driving assembly and first and second contacts. A trigger signal is generated and the driving assembly is controlled to release braking on the rotary shaft when the first and second contacts contact each other.

The present invention provides various aspects of a novel safety light that can be attached to a bicyclist or around the body of an athlete so as to define a well lit, safe distance to avoid collision by a motorist. The present safety concerns would find advantage in an easy to attach safety light that is much larger, more conspicuous and one that provides greater lumens. It would be desirable for athletes and the sports industry if there was provided an improved safety light system to provide a significant warning to let motorists know the safe distance that any motorist and/or his vehicle needs to avoid so as not to hit the cyclist or athlete.
