发明名称 Temporary work light string with variably-positionable and re-positionable readily-replaced lamp, optionally with integral hangers, that are optionally electrically connected to plural electrical circuits
摘要 A work light string removably physically mounts and electrically attaches lamps anywhere along it is length, with ready hand positioning and re-positioning of desired numbers of lamps at desired positions, and replacement of damaged lamps. The work light string can have one, or, more preferably two separate electrical circuit in which case each lamp and any external electrical load(s) can be powered by either circuit.

主权项 1. A work light string comprising of an electrical cable comprising three electrical conductors therein and a lamp with a bulb for connecting to the electrical cable, the lamp comprising: a middle assembly comprising a first screw thread for receiving the bulb, two metal conductors for circuit connecting to the bulb, and two prongs each of which is electrically connected to one of the two metal conductors, a second screw thread, a channel extending longitudinally across and into the second screw thread wherein the two prongs are at a bottom of the channel and wherein the electrical cable is configured to be laid in the bottom of the channel on the two prongs; a top assembly comprising a first screw thread and a second screw thread for threading engagement with the second screw thread of the middle assembly to engage and disengage the middle assembly from the top assembly; and a bridle ring having a first screw thread for threading engagement with the first screw thread of the top assembly, and a base at a bottom of the bridle ring, wherein the bridle ring is configured for threading the base of the bridle ring downward in the channel and pressing the cable onto the two prongs of the middle assembly so that each of the two prongs come into electrical contact with one of the three electrical conductors in the electrical cable.
