Abstract: In an exit sign, a canopy bracket has a pair of resilient spring fingers which are inserted through a central circular opening of a mounting plate mounted to a standard electrical box located in a wall or ceiling. The spring fingers temporarily secure the canopy bracket to the mounting plate thus allowing an electrician to easily align and secure screws to the mounting plate, thereby greatly facilitating installation. The wires from the electrical box are extended through mounting plate and the canopy prior to securing the canopy to the mounting plate. Once secured, the user simply fits a hub portion of the canopy bracket telescopically within an opening with the exit sign housing. Spring capture barb members of the hub engage the housing to fixedly secure the exit sign to the wall or ceiling. Then the user connects the wires extending from the canopy bracket to those in the exit sign.

Abstract: A portable drakroom safelight which incorporates several features which enhance its usefulness in a darkroom. The portable safelight includes a lamp, a safelight filter, rechargeable batteries, a light sensor, and control means. The safelight filter filters all light produced by the lamp, thus making the safelight safe for use in a darkroom and with photosensitive materials. A surface mounting bracket or stand supports the portable safelight and includes a transformer for converting household electric current into low voltage direct current suitable for use by the portable safelight. When the portable safelight is removed from the mounting bracket it automatically switches to operate from the rechargeable batteries and its illumination level is automatically reduced. The lamp is automatically turned off or on when the light sensor detects the presence or absence of ambient white light.
