Abstract
Abstract A novel lamp assembly and method of production therefor which provides a waterproof, omni-directional, and non-corrosive means for illuminating a terrarium or aquarium. The lamp assembly is particularly suited for use in combination with salt water aquariums owing to its non-corrosive quality. The lamp is constructed using a novel sealing process which encapsulates all electrical connections and any starting apparatus within a waterproof sealant contiguous with the ends of a conventional fluorescent lighting tube. The resulting one-piece construction produces a safe, inexpensive, and disposable lighting apparatus.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
100 words
A non-corrosive lamp assembly comprising in a one-piece, noncorrosive waterproof lamp assembly: a fluorescent lighting tube presenting electrical connection terminals; conduction means permanently affixed to the terminals of the tube and operable to supply proper electrical current to the tube; non-corrosive sealant means comprising a closed mass applied in fluid form and hardening, thereby adhering to the fluorescent lighting tube in a sealing relationship by encapsulating the ends of the tube and corresponding electrical connections, the sealant maintaining the tube and corresponding electrical connections in a waterproof condition; and power supply means connected to the conduction means energizing the lamp.
Claim 2
Dependent Claim
100 words
A non-corrosive lamp assembly comprising in a one-piece, noncorrosive waterproof lamp assembly: a fluorescent lighting tube presenting electrical connection terminals; conduction means permanently affixed to the terminals of the tube and operable to supply proper electrical current to the tube; non-corrosive sealant means comprising a closed mass applied in fluid form and hardening, thereby adhering to the fluorescent lighting tube in a sealing relationship by encapsulating the ends of the tube and corresponding electrical connections, the sealant maintaining the tube and corresponding electrical connections in a waterproof condition; and power supply means connected to the conduction means energizing the lamp.
Claim 3
Dependent Claim
29 words
A non-corrosive aquarium lamp as defined in claim 1 wherein said conduction means comprises a bi-stable switching element disconnecting certain of the power supply circuits at a predetermined time.
Claim 4
Dependent Claim
149 words
A non-corrosive aquarium lamp comprising: a glass envelope; a gaseous discharge medium within the glass envelope which produces radiation upon exposure to electrical excitation; a coating of fluorescent material on the inside of the glass envelope which emits visible light upon being exposed to the radiation produced by the gaseous discharge medium; excitation means capable of producing electrical excitation within the glass envelope; conducting means permanently connected to the excitation means providing a circuit for supplying electrical current to the excitation means; first encapsulation means comprising a closed mass of sealant to hold the connections between the conducting means and the excitation means in preset physical relation; second encapsulation means comprising a closed mass adhering to the glass envelope in a sealing relationship to seal the end of the envelope and first encapsulating means in waterproof condition; power supply means connected to the second conducting means energizing the lamp.
Claim 5
Dependent Claim
149 words
A non-corrosive aquarium lamp comprising: a glass envelope; a gaseous discharge medium within the glass envelope which produces radiation upon exposure to electrical excitation; a coating of fluorescent material on the inside of the glass envelope which emits visible light upon being exposed to the radiation produced by the gaseous discharge medium; excitation means capable of producing electrical excitation within the glass envelope; conducting means permanently connected to the excitation means providing a circuit for supplying electrical current to the excitation means; first encapsulation means comprising a closed mass of sealant to hold the connections between the conducting means and the excitation means in preset physical relation; second encapsulation means comprising a closed mass adhering to the glass envelope in a sealing relationship to seal the end of the envelope and first encapsulating means in waterproof condition; power supply means connected to the second conducting means energizing the lamp.
Claim 6
Dependent Claim
29 words
A non-corrosive aquarium lamp as defined in claim 3 wherein said conducting means comprises a bi-stable switching element disconnecting certain of the power supply circuits at a predetermined time.
