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.
