The present invention shows a system for hanging lights and cable hooks from an I-beam overhead girder in a construction site for the purpose of getting lights and cables off the floor in order to meet construction regulations.

A winch comprises a cable roll; a cable having one end fixed to the cable roll and another end configured to electrically connect an electric device to the cable, wherein the cable is further configured to provide the electric device with electric power and/or with data; a framework to which the cable roll is mounted; measuring means connected to the framework and configured to provide data related to the length of an unwound part of the cable; and processing means configured to control winding and unwinding of the cable based on data provided by the measuring means. The cable has a predetermined reference state at which a predetermined fixed reference point is at a reference position in relation to a coordinate system, wherein the length of unwound cable is defined as the distance measured along the cable, between the location of the predetermined fixed reference point and the reference position.

A fastener device includes a first fastener part and a second fastener part which can be mounted on one another along a closing direction and are held against one another in a closed position, and are releasable from one another in order to open the fastener device. The second fastener part has a winding element on which a tension element can be arranged and which is rotatable relative to the first fastener part in order to wind up the tension element on the winding element in a winding direction.

An emergency lighting assembly includes a drum that has a chute extending into the drum. A spool is rotatably disposed within the drum. The spool is biased to rotate in a first direction and the spool is urgeable to rotate in a second direction. A locking mechanism is movably integrated into the drum to inhibit the spool from rotating and to facilitate the spool to rotate. A light rope is attached to the spool and the light rope can be pulled outwardly through the chute thereby facilitating the light rope to be positioned on the roadway. The light rope is illuminated when the light rope is turned on to visually alert motorists on the roadway to the hazard on the roadway. A clasp is attached to the light rope and the clasp is attachable to a support object for retaining the light rope in a desired position on the roadway.

A multi-positional bar shaped light assembly includes a rear housing defining an interior and an open front. The housing further has a rear wall defining two identical sets of mounting holes therethrough, one at a midpoint of the housing and a second set at one end of the housing. The second set being oriented at a right angle with respect to the first set. A printed circuit assembly is mounted within the rear housing and includes a plurality of linearly aligned light emitting diodes arranged thereon oriented to emit light through the open front of the rear housing. A reflector has an open back and is mounted to the printed circuit assembly, and a translucent lens is attached to the rear housing at the open front. A support stand is affixed to the rear housing at one of the first and second sets of mounting holes.

Methods, systems and devices associated with an electronic candle are disclosed. One example includes an electronic candle includes an outer shell including a through-hole, a light-emitting assembly including a flame sheet configured to protrude through the through-hole, an inner shell positioned within the outer shell, and a self-locking device positioned within a cavity of the inner shell. The self-locking device is configured to operate in (1) a locked state when a switch locks a spring in a compressed state and (2) an unlocked state when the switch releases the spring to be in a relaxed state. The electronic candle also includes a bottom case such that the bottom case is enclosed within the outer shell when the self-locking device is in the locked state and the bottom case is exposed to an external environment beneath the outer shell when the self-locking device is in the unlocked state.

The present disclosure discloses a lighting apparatus and relates to a lighting field. The lighting apparatus includes an outer housing, an inner housing, a face ring, a functional module and a first conductive wire. A portion of the inner housing is arranged inside an accommodating cavity and separates the accommodating cavity of the housing into a light source cavity and a via cavity; the face ring is located outside the accommodating cavity and connected with the inner housing, and encloses to form an installation cavity; the installation cavity is sequentially in communication with the via cavity and the first via hole, so that the functional module mounted in the installation cavity may be electrically connected with the first conductive wire; and the first conductive wire sequentially passes through the via cavity and the first via hole to extend out of the housing.
