Patent ID: 7744256

Claim:
A lighting fixture comprising: a holding plate including a flange defining an aperture in the holding plate; a heat sink including a lamp support surface; at least one mounting bracket interconnecting the heat sink to the holding plate, wherein the lamp support surface is positioned opposed to the holding plate aperture; and an LED wafer, which includes a first surface having a plurality of light emitting LEDs, in thermal communication with the lamp support surface; and a reflector, having a proximal end defining a first opening and a distal end defining a second opening, mechanically coupled to the holding plate flange such that a longitudinal axis between the proximal end and distal end intersects a plane containing the holding plate; wherein the reflector has a shielding angle θ measured with respect to a central longitudinal axis of the reflector, wherein the shielding angle is configured to produce a reflector efficiency approaching 90 percent and a visual comfort probability index approaching 100 percent.
