发明名称 DOWNWARD ILLUMINATION ASSEMBLY
摘要 An illumination assembly comprising an LED module removably supported within a lamp housing configured to be mounted on an elevator ceiling panel in a position to direct light from the LED module downward into an elevator passenger compartment through an opening in the housing and a hole in the ceiling panel. The LED module is removable from the housing from below the ceiling panel through the housing opening and the hole in the ceiling panel. Threads formed in an inner cylindrical wall of the lamp housing receive threads formed in an outer circumferential surface of the LED module in threaded engagement. The LED module includes at least two LED module removal surfaces positioned to be engaged by respective engagement surfaces of a tool configured to apply torque to and rotate the LED module relative to the lamp housing.
