BATTERY POWERED LIGHT SOURCE |
摘要 |
A battery powered light source comprising an electric light bulb; a plurality of air cathodes (34); a plurality of metal anodes (36), one for each cathode; a plurality of electrically nonconductive housings (16/18) disposed adjacent to each other, wherein each housing encloses a respective chamber (22) containing one cathode and one anode which are spaced from each other and form an anode-cathode pair and also encloses a cavity (22a) 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 (32) from its chamber to an adjacent housing, and an opening (28) through which a surface of the contained cathode is exposed to air in the passage. The housings (16/18) are secured to each other in such arrangement that their respective air-passage-defining portions co-operatively 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. |
