Abstract
A conventional acorn style globe is described incorporating the utilization of LED's as an illumination source. A supporting heat dissipation plate is provided which extends to the exterior periphery of the acorn style luminaire allowing heat to transfer from the LED's directly to the exterior of the acorn style luminaire while maintaining the integrity of an acorn style globe construction. A plurality of individually orientable lenses on each of the LED's positioned within the interior of the globe allow for efficient downlight and desirable optical characteristics. Interior access may be provided through removal of the globe top to thereby provide accessibility to the LED board mounted on the heat transfer plate.
