Abstract
Abstract A floating utility light including a light bulb and a housing including a frame defining a central aperture through which the enlarged portion of the light bulb protrudes, and a concave section connected at its periphery to the edges of the frame and extending over the rear portion of the light bulb to which the electrical connections are made. The housing is substantially water impervious and is of low profile so that it floats with the portion of the bulb extending through the aperture of the frame immersed in water. The concave portion of the housing is translucent, so that when the light bulb is illuminated, the concave portion of the housing will glow or emit dispersed light, while a beam of light will be directed into the water. An arcuate handle is connected at its ends to the concave housing for convenience in retrieving the utility light from the water and for handling the light in other situations.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
A light fixture comprising a lamp including a large diameter bulb portion with a generally conical reflecting portion and electrical connections at the apex of said reflecting portion, a substantially flat frame defining an opening surrounding said bulb portion at a line of contact spaced from said reflecting portion, and a concave translucent housing connected at its edges to the outer edges of said frame and extending over said electrical connections of said lamp to form with said frame and lamp a substantially waterproof enclosure, the distance across said frame being at least twice the distance from the exposed portion of said bulb portion to the portion of said concave housing adjacent the electrical connections of said lamp.
Claim 2
Dependent Claim
118 words
A light fixture comprising a lamp including a large diameter bulb portion with a generally conical reflecting portion and electrical connections at the apex of said reflecting portion, a substantially flat frame defining an opening surrounding said bulb portion at a line of contact spaced from said reflecting portion, and a concave translucent housing connected at its edges to the outer edges of said frame and extending over said electrical connections of said lamp to form with said frame and lamp a substantially waterproof enclosure, the distance across said frame being at least twice the distance from the exposed portion of said bulb portion to the portion of said concave housing adjacent the electrical connections of said lamp.
Claim 3
Dependent Claim
50 words
The light fixture of claim 1 and wherein said concave housing is fabricated of a flexible plastic material and defines an aperture therein so that the light fixture can be oriented in an attitude where said aperture faces downwardly and the concave housing squeezed to expel any liquid trapped therein.
Claim 4
Dependent Claim
87 words
The light fixture of claim 1 and further including a handle curved along its length in a radius less than the radius of curvature of said concave housing, said handle being joined at its ends to opposite sides of said concave housing at positions closely spaced from said frame, and electrical conducting means extending from the center portion of said handle, to the ends of said handle, through said concave Housing at the ends of said handle, and to the electrical connections of said conical reflecting portion.
Claim 5
Dependent Claim
121 words
A utility light comprising a lamp including a large diameter convex lens, a reflecting portion joined to said lens and electrical connections positioned centrally of said reflecting portion, a generally flat frame defining a central opening joined to said lens inwardly of the edge of the lens and extending outwardly away from said lens in a plane generally perpendicular to the central axis of said convex lens to cause light emitted from said lens to illuminate both sides of said frame, and a concave translucent housing connected at its edges to said frame in said plane, said housing extending over said reflecting portion and electrical connections of said lamp to form with said frame and lamp a substantially water proof enclosure.
Claim 6
Dependent Claim
121 words
A utility light comprising a lamp including a large diameter convex lens, a reflecting portion joined to said lens and electrical connections positioned centrally of said reflecting portion, a generally flat frame defining a central opening joined to said lens inwardly of the edge of the lens and extending outwardly away from said lens in a plane generally perpendicular to the central axis of said convex lens to cause light emitted from said lens to illuminate both sides of said frame, and a concave translucent housing connected at its edges to said frame in said plane, said housing extending over said reflecting portion and electrical connections of said lamp to form with said frame and lamp a substantially water proof enclosure.
Claim 7
Dependent Claim
18 words
The utility light of claim 4 and wherein said lens is convex and protrudes through said frame member.
