Abstract: A combination flashlight and electrical power source assembly includes an emitter and fuel system module, a fuel cartridge module fixed to the emitter and fuel system module, a photovoltaic conversion module attachable to a selected one of the emitter and fuel system module and the fuel cartridge module, and a flashlight lens module attachable to the other of the emitter and fuel system module and the fuel cartridge module. When the photovoltaic conversion module is attached to the emitter and fuel system module and the flashlight lens module is attached to the fuel cartridge module, the photovoltaic conversion module is active, the flashlight lens module functions as an end cap, and the assembly functions as an electrical power source.

Abstract: Emergency lighting housing/canopy interfacing structure. The structure employs one or more fasteners which may be positioned into place quickly and simply without the aid of tools in order to retain the housing and canopy securely together. Additional redundance members such as conventional snap-fitting barb members may additionally be employed to assist in installation and for extra safety. The present invention accordingly provides emergency lighting housing/canopy interfaces which allow simple, quick and reliable installation of emergency lighting fixtures, but which add additional structure to support the housing and the considerable load imparted by transformers, batteries and other structure within the housing. A preferred embodiment includes an elongated fastener which may be snapped and rotated into place into mounting posts formed on the canopy.
