Title: Light fixture with submersible enclosure for an electric discharge lamp
Inventor: FRANKIEWICZ GREGORY P
IPC: F21V25/02
Filed: 2002-07-23
Abstract: A light fixture with a submersible enclosure for an electric lamp (e.g, HID lamp) is disclosed. The fixture includes a ballast for supplying power to a high intensity discharge lamp. A submersible enclosure seals the lamp from water in normal operation. The fixture includes a water-sensitive circuit having a conductance that increases in response to water that leaks into the enclosure for conducting current from the ballast and limiting the ballast voltage. Alternatively, the submersible enclosure may contain a power lead for supplying power to an electrical load such as a lamp ballast, a non-ballasted lamp, or a color wheel. The power lead includes a fuse region that corrosively reacts in the presence of leaked water in the container, so as to sufficiently wither away the fuse region and terminate power to the load. The foregoing alternative versions may advantageously be combined.
