Abstract
A battery powered light source comprising an electric light bulb; a plurality of air cathodes; a plurality of metal anodes, one for each cathode; a plurality of electrically nonconductive housings disposed adjacent to each other, wherein each housing encloses a respective chamber containing one cathode and one anode which are spaced from each other and form an anode-cathode pair and also encloses a cavity which is below the anode-cathode pair and is in fluid flow communication with the chamber, each housing having a portion defining at least one air passage from its chamber to an adjacent housing, and an opening through which a surface of the contained cathode is exposed to air in the passage. The housings are secured to each other in such arrangement that their respective air-passage-defining portions cooperatively define at least one common air passage. Circuit elements are provided for electrically connecting the anode-cathode pairs to each other and to the electric light bulb.
