Outdoor luminaire using light emitting diodes
First Claim
1. An outdoor luminaire using light emitting diodes for street, pathway and general area lighting, comprising:
- a means to provide protected access for installing the electrical connections to power the luminaire;
a means for proper alignment of the secondary optic and the light emitting diodes in order to provide for correct light shaping and maximum luminous intensity, with respect to user requirements;
a means for securing the luminaire to almost any size arm or pole, allowing for correct orientation of the luminaire, with regard to pitch and roll;
a means for supplying the light emitting diodes with power that is precisely regulated and protected with regard to current, ensuring light emitting diode longevity goals and light output are met;
a means for providing for a heat sink with large surface areas from which to dissipate heat from the light emitting diodes.

Abstract
A luminaire that uses Light Emitting Diodes as a light source, and which is intended to be securely mounted outdoors on a pole or arm of widely varying diameter. The luminaire is modular, in the sense that a major component may be removed, repaired and/or replaced for maintenance or for upgrade purposes, without tools, and without modification to any other component in the luminaire. The luminaire'"'"'s main component is a light engine comprised of Light Emitting Diodes mounted to a thermally conductive circuit board, which in turn is mounted to a thermally dissipative heat sink which resides on the outside of the luminaire. The thermally dissipative heat sink is specifically constructed to take full advantage of horizontal surface winds at the recommended mounting height of the luminaire, to aid in the dissipation of heat created by the Light Emitting Diodes and power components. The Light Engine is mounted in a housing facing downward, with respect to light output, directly over an aperture, or hole in the lower housing, whereby one of several different lenses may be placed to provide a desired photometric output. This structure and method of manufacture allows for use of almost any LED technology that exists, as well as those in the emergent and conceptual stages.
