发明名称 Maintenance enhanced illumination assembly
摘要 An illumination assembly allows quick and easy access to light fixtures that are mounted extended far enough away from a catwalk of a lighted sign such as a billboard as to be inaccessible to a worker on the catwalk. An elongate tubular member is pivotally mounted on a support affixed to the catwalk. A light fixture is mounted on the distal end of the member. A control mechanism enables the member to be fixed in extended position for use in illuminating the sign. The control mechanism enables the member to pivot to a position where the light fixture is adjacent the catwalk, for changing the light bulb or other maintenance. The control mechanism is accessible from the catwalk.
