Abstract: An assembly for mounting a light fixture in a hole in a ceiling panel and including an annular trim ring that's held upward against a lower surface of a ceiling panel by the light fixture to be mounted, such that the trim ring spans an annular gap between such light fixture and the ceiling panel hole. A top plate is carried by the ceiling panel across the ceiling panel hole and includes a top plate hole that receives the light fixture to be mounted such that the top plate spans an annular gap between the light fixture and the ceiling panel hole. A mount supports the light fixture on the top plate in a position holding the trim ring up against the lower surface of the ceiling panel.

Abstract: A light fixture mounting assembly that includes a lamp housing having a sidewall and an opening defined by a rim at one end of the sidewall and a detent extending outward from the sidewall in a position to engage an outer surface of a panel when the housing is in an installed position. A lamp module is carried within the lamp housing and comprises a lamp positioned to emit light through the housing opening. The lamp housing is configured to carry either a spring clip-type retainer or a hose clamp-type retainer to hold the lamp housing in the installed position.

Abstract: An elevator interior illumination assembly for providing a rectilinear source of illumination in an elevator ceiling panel. An LED, reflector, and a rectilinear lens are carried by the housing, and the reflector and lens are configured to direct light emitted by the LED into an evenly-distributed rectilinear light emission image across the lens.

Abstract: An interior illumination assembly comprising a lamp housing mountable on an interior panel and a lamp removably supportable within the lamp housing. The lamp includes an LED module carrying an LED and removably receivable by the lamp housing into an installed position in the lamp housing. A lens is disposed across the module opening and a reflector carried by the LED module reflects light from the LED through the lens into the compartment.

Abstract: An elevator emergency LED lighting power supply assembly including an inverter that receives DC power from a battery and outputs backup power to LED lamps of an elevator lighting system. An LED driver is connected to the inverter, is connectable to an LED lamp of the elevator lighting system, receives AC power from the inverter, and outputs DC power sufficient to power an LED lamp. A relay is connected between the inverter and the LED driver, is connectable to a primary elevator electrical power supply, and allows AC power to flow from a primary elevator electrical power supply to elevator lighting system LEDs through the LED driver as long as AC power is available from a primary elevator electrical power supply. Upon loss of power from the primary elevator power supply the relay switches contacts and provides to the LED driver AC power received from the inverter.

Abstract: A method is provided for equalizing emitted light levels between light fixtures that use LEDs to produce light. The method includes gaining access to LED light fixtures from within a compartment in which the fixtures are mounted, and adjusting LED dimmers of the LED light fixtures to adjust the light emission levels of the LED light fixtures to generally match one another.

Abstract: An illumination system including a lamp housing that may be mountable on a ceiling panel and a lamp supported within the lamp housing in a position to emit light from an opening in the housing. The lamp includes at least one LED that's removable through the housing opening.

Abstract: A downward illumination assembly for directing light downward from the ceiling area of a room. A lamp housing has an open lower end positionable adjacent an opening in a ceiling panel. A power supply module is removably supported in an installed position on the housing. The power supply module carries a lamp socket such that, when the power supply module is in the installed position, a lamp plugged into the lamp socket is disposed in a position to radiate light out the lower end of the lamp housing and through an opening in a ceiling panel that the housing is mounted on. The power supply module is removable interiorly of the lamp housing through the open lower end of the lamp housing.
