Light replacing apparatus for replacing bulbs in street lamps

摘要

A method for changing a light bulb in a parking light pole, comprising disposing a housing on the top of a light pole for holding a lamp holder having a lamp disposed therein, holding the lamp holder in the housing by urging the lamp holder downward, removing the lamp holder by urging a removal apparatus up through an annulus in the center of the light pole to urge a plurality of pivoting members outward and away from the bottom surface of the lamp holder to allow the lamp holder to fall and be captured by the removal apparatus, replacing the lamp holder by disposing the lamp holder in an installation device, urging the installation device upward such that the lamp holder causes the pivoting members to urge outward, urging the installation device down in the annulus to allow the lamp holder to be urged downward, and removing the installation device.

主权项

1. A system for replacing a bulb in a light fixture mounted on a light pole with a hollow core, comprising:
a mobile lamp fixture for containing the bulb and interfaced with electrical wires that extend from a first point at a distal end of the pole from the light fixture and extending through the hollow core to the light fixture, the mobile lamp fixture dimensioned to pass through the hollow core; and a receiving fixture disposed and fixed on the light fixture, having:
a releasing collar for releasably holding the mobile lamp fixture in place in the light fixture, the releasing collar operable in a first extracting mode to allow the mobile lamp fixture to be removed and extracted through the hollow core and, in a second insertion mode, to receive and secure the mobile lamp fixture through the hollow core; wherein the mobile lamp fixture includes:
a supporting body,an electrical interface for receiving the bulb and interfacing the bulb with the electrical wires extending from the opposite side thereof from the bulb, anda supporting collar disposed about the periphery of the supporting body in a plane perpendicular to the axis of the hollow core of the pole; and wherein the releasing collar includes:
a fixed collar disposed about the interior of the hollow core proximate the light fixture,a spring biased receiving collar for interfacing with the fixed collar via a spring and urging the spring biased receiving collar away from the fixed collar toward the distal end of the hollow core, anda releasing member for interfacing with the mobile lamp fixture collar to allow the mobile lamp fixture to pass thereby in the insertion mode with an external insertion device and maintain it in contact with the spring biased receiving collar in a secured manner and to release the mobile lamp fixture in the extraction mode in response to an insertion device being inserted therein and interfaced there with to allow the mobile lamp fixture to be removed through the hollow core.
