Abstract
An economical LED light module configured to emit a uniform pattern of light from a single LED utilizing a minimal amount of energy and exhibiting a long and useful life is provided. The LED light module includes a main hyperbolic reflector and a plug receptacle having an electrical connector configured for electrical communication with a power source. A LED is mounted in electrical communication with the electrical connector. An elongate light pipe extends between a light receiving end configured to receive light emitted from the LED and a light emitting end. The light emitting end has a parabolic reflector positioned concentrically about a focal point of the hyperbolic reflector.
Claims12
A LED light module, comprising:
- a housing presenting an outer surface and an opening;
- a socket received in said opening of said housing, said socket presenting a through passage;
- a main hyperbolic reflector including a base end disposed radially outwardly of said socket and fixed to said outer surface of said housing, said base end of said main hyperbolic reflector presenting an opening surrounding said socket, and said main hyperbolic reflector including a reflector surface extending upwardly from said base end;
- an electrical connector configured for electrical communication with a power source;
- a LED mounted in electrical communication with said electrical connector;
- an elongate light pipe disposed in said through passage of said socket and extending between a light receiving end configured to receive light emitted from said LED and a light emitting end, said light emitting end having a parabolic reflector positioned concentrically about a focal point of said hyperbolic reflector;
- a base operably attached to said socket;
- and
- a cover seal member operably attaching said base and said socket, said cover seal member extending between said elongate light pipe and said base and spacing said elongate light pipe from said socket.
An LED light module, comprising:
- a housing presenting an outer surface and an opening;
- a socket received in said opening of said housing, wherein said socket includes a side wall presenting a through passage;
- an electrical connector configured for electrical communication with a power source;
- a LED mounted in electrical communication with said electrical connector;
- a base having one end operably attached to said socket and an inner cavity;
- a PCB disposed in said inner cavity of said base and in electrical communication with said electrical connector and said LED;
- a cover seal member operably attaching said one end of said base to said socket and sealing said inner cavity;
- a main hyperbolic reflector including a base end disposed radially outwardly of said socket and fixed to said outer surface of said housing, said base end of said main hyperbolic reflector presenting an opening surrounding said socket, and said main hyperbolic reflector including a reflector surface extending upwardly from said base end;
- an elongate light pipe disposed in said through passage of said socket and extending between a light receiving end configured to receive light emitted from said LED and a light emitting end, said elongate light pipe having a cylindrical portion and a bowl-shaped portion atop said cylindrical portion, said cylindricaln a constant outside diameter from said light receiving end to said bowl-shaped portion, said bowl-shaped portion including said light emitting end having a parabolic reflector positioned concentrically about a focal point of said hyperbolic reflector;
- said cover seal member extending between said elongate light pipe and said one end of said base, and
- said cover seal member spacing said elongate light pipe from said wall of said socket.
