  • Patent number: 9200784
    Abstract: 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.

  • Patent number: 7066617
    Abstract: A downward illumination assembly for directing light downward from the ceiling area of a room includes a lamp housing having a closed upper end, an open lower end disposed axially opposite the closed upper end, and a housing wall extending from around a periphery of the upper end to and defining the open lower end. The lower end is positioned adjacent an opening in a ceiling panel. A lamp is supported in a lamp socket within the lamp housing in a position to radiate light through the lower end of the housing and through the opening in the ceiling panel. A module is removably supported on the housing and carries the lamp socket. The lamp socket is removable from the lamp housing with the module to allow the lamp socket and/or associated wiring to be serviced or replaced without removing the lamp housing from the ceiling panel or disconnecting and lowering the ceiling panel from its support structure.

  • Patent number: 5593347
    Abstract: An emergency ventilation system for elevator cabs includes a low voltage power source defined by the secondary winding of a stepdown transformer having its primary winding connected across a primary power source. An emergency power circuit has a single pole, double throw relay located in a normal power position when the primary power source is "on" wherein it connects the low voltage power source to the ventilating fans. The single pole, double throw relay has an emergency position wherein it is positioned to connect the emergency battery source to the ventilating fans so as to operate them independently of the primary power source for providing uninterrupted ventilation to the elevator cab.
