Abstract
A lamp fixture is disclosed having a construction which permits a dome above a light source to drain the condensate which forms on its inside surfaces to drip areas along the lower portions of the sides of the dome which are beyond the reach of the light source or its electrical components. The condensate drops from the drip areas onto the inside surfaces of a lamp fixture lens disposed beneath the dome, runs down the inside surfaces of the lens, and issues through weep holes through the lower extremities of the sides of the lens onto a horizontally disposed surface outside the lens. The condensate evaporates from or drips away from the horizontally disposed surface.
Claims13
A lamp fixture comprising
- a refractor for receiving light from a source of light and distributing light from the source into a far field,
- the refractor having sloping sides extending upwardly to form at least one inclined surface from a lower end of the refractor having a smaller orifice to an upper end of the refractor having a larger orifice,
- a dome member for dispersing heat from inside the refractor disposed upon the upper end of the refractor,
- the source of light inside and adjacent the lower end of the refractor,
- a base canister supporting the refractor and the dome member and containing means for supplying current to the source of light,
- a collar member intermediate the canister and the refractor having a neck portion and a flange portion,
- the flange portion overlying the canister and outwardly of the neck portion and providing a seat around the neck portion for the lower end of the refractor,
- the neck portion extending upwardly from the flange portion into the lower end of the refractor and walling off the means for supplying current to the source of light from the sloping sides of the refractor and the flange portion of the collar member,
- means inside the dome member for condensation collected on an inside surface of the dome member to drip inside the refractor onto the inclined surface of the refractor, and
- means extending through the sides of the refractor for condensation collected inside and adjacent the lower end of the refractor to flow away from the neck portion of the collar member to outside of the refractor.

An electromagnetic radiation receiving fixture comprising
- a refractor for receiving radiation from a source of radiation in a distributed far field,
- the refractor having sloping sides extending upwardly to form at least one inclined surface from a lower end of the refractor having a smaller orifice to an upper end of the refractor having a larger orifice,
- a dome member for dispersing heat from inside the refractor disposed upon the upper end of the refractor,
- an electromagnetic radiation detecting means inside the refractor,
- a base canister supporting the refractor and the dome member and containing means for receiving output from the electromagnetic radiation detecting means,
- a collar member intermediate the canister and the refractor and having a neck portion and a flange portion,
- the flange portion overlying the canister and outwardly of the neck portion and providing a seat around the neck portion for the lower end of the refractor,
- the neck portion extending upwardly from the flange portion into the lower end of the refractor and walling off the means for receiving output from the electromagnetic radiation detecting means from the sloping sides of the refractor and the flange portion of the collar member,
- means inside dome member for condensation on the inside surface of the dome member to drip inside the refractor onto the inclined surface of the refractor, and
- means extending through the sides of the refractor for condensation collected inside and adjacent the lower end of the refractor to flow away from the neck portion of the collar to the outside of the refractor.

A lamp fixture comprising
- a refractor for receiving light from a source of light and distributing light from the source into a far field,
- the refractor having vertically disposed sides forming at least one surface inside the refractor and extending substantially from a lower end of the refractor to an upper end of the refractor,
- a cover member disposed upon the upper end of the refractor,
- the source of light inside the refractor,
- a base canister supporting the refractor and containing means for supplying current to the source of light,
- a collar member intermediate the canister and the refractor and having a neck portion and a flange portion,
- the flange portion overlying the canister and outwardly of the neck portion and providing a seat around the neck portion for the lower end of the refractor, and
- the neck portion extending upwardly from the flange portion into the lower end of the refractor and walling off the means for supplying current to the source of light from the sides of the refractor and the flange portion of the collar member,
- means for conducting condensation collected on the cover member to the inside surface of the refractor, and
- means extending through the sides of the refractor for condensation collected inside and adjacent the lower end of the refractor to flow away from the neck portion of the collar member to outside of the refractor.
7 more elements
A lamp fixture comprising
- a refractor having an upper end and a lower end and receiving light from a source of light and distributing light from the source into a far field,
- the source of light inside the refractor,
- a dome member made of electrically conductive material for dispersing heat from inside the refractor disposed upon the upper end of the refractor,
- a base canister electrically connected to ground supporting the refractor and the dome member and containing means for supplying current to the source of light,
- a collar member intermediate the canister and the refractor and having a neck portion and a flange portion,
- the flange portion overlying the canister and outwardly of the neck portion and providing a seat around the neck portion for the lower end of the refractor, and
- the neck portion extending upwardly from the flange portion into the lower end of the refractor,
- an electrically conductive clamp member attached to the dome member and the collar member clamping the refractor between the dome member and the collar member and electrically connecting the dome member and the collar member, and
- an electrically conductive connection member affixed to the collar member and the base canister, thereby connecting the dome member electrically to ground.
