Abstract
Abstract A submersible lamp having a housing and a lens with a bulb carried therein in optical alignment with the lens. A pair of terminal connections are provided for electrically coupling the bulb to a source of illuminating energy. The housing forms an open air chamber to define a volume of air such that upon submersion of the housing in water, the air is compressed to create a force sufficient to prevent the water from rising within the housing above a pre-determined level into contact with the bulb and terminal connections.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
In a submersible electric lamp having a housing defining an enclosure for retaining a predetermined volume of air and an opening formed in said housing through which liquid may pass such that upon submersion of said housing in liquid to a level below said opening formed therein said predetermined volume of air will be compressed creating a force sufficient to prevent the liquid which may pass within said housing from rising above a predetermined level, and an electric lamp carried within said housing above said predetermined level and having electrical leads for coupling said electric lamp to a source of illuminating electrical energy for lighting said electrical lamp, the improvement comprising terminal coupling means carried within said lamp housing at a position above said predetermined level to which liquid will rise therein for electrically coupling said electrical leads to a source of illuminating electrical energy and thereby preventing contact of the coupling with the liquid when submerged therein.
Claim 2
Dependent Claim
158 words
In a submersible electric lamp having a housing defining an enclosure for retaining a predetermined volume of air and an opening formed in said housing through which liquid may pass such that upon submersion of said housing in liquid to a level below said opening formed therein said predetermined volume of air will be compressed creating a force sufficient to prevent the liquid which may pass within said housing from rising above a predetermined level, and an electric lamp carried within said housing above said predetermined level and having electrical leads for coupling said electric lamp to a source of illuminating electrical energy for lighting said electrical lamp, the improvement comprising terminal coupling means carried within said lamp housing at a position above said predetermined level to which liquid will rise therein for electrically coupling said electrical leads to a source of illuminating electrical energy and thereby preventing contact of the coupling with the liquid when submerged therein.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 wherein said terminal coupling means are carried by a bulb slide positionable within said housing through an opening formed therein.
Claim 4
Dependent Claim
28 words
The apparatus of claim 1 wherein said terminal coupling means comprises a terminal shroud formed with an interior wall having an opening therein and substantially circular in configuration.
Claim 5
Dependent Claim
33 words
The apparatus of claim 2 wherein said terminal coupling means comprises a substantially cylindrical terminal shroud extending outwardly from said bulb slide and having an opening therein for receiving an electrical lead wire.
Claim 6
Dependent Claim
18 words
The apparatus of claim 4 further including means for securing an electrical lead wire within said terminal shroud.
Claim 7
Dependent Claim
43 words
The apparatus of claim 4 wherein said terminal shroud has a substantially circular interior wall and said opening formed therein is positioned to cause an electrical wire passed therethrough to engage said interior wall and be flexed into a configuration conforming substantially thereto.
Claim 8
Dependent Claim
30 words
The apparatus of claim 1 wherein said electric lamp and said terminal coupling means are both carried by a bulb slide positionable within said housing through an opening formed therein.
