distances is provided the led luminaire includes a housing a printed circuit board assembly thermally coupled to the housing a plurality of high brightness led emitters thermally coupled to the printed circuit board assembly to form a linear array and a linear reflector assembly attached to the housing to concentrate the light generated by the led emitters over a beam angle formed by the upper surface of the housing and the linear reflector assembly application_number US 201213366520 A description the invention will now be described with reference to the drawing figures in which like reference numerals refer to like parts throughout embodiments of the present invention advantageously provide a widely spaced linear array of high brightness hb emitters used in conjunction with a linear reflector assembly that prevents loss of led luminaire output in unused directions while at the same time providing uniform light pattern blending at close distance for the spaced led emitters in these embodiments a widely spaced array of hb led emitters is thermally bonded to a linear shaped luminaire by means of a thermal clad or other high thermal efficiency pcb design the hb emitters have a much higher thermal efficiency than low or medium power led emitters which translates directly to higher power conversion efficiency and higher allowable operating temperatures these factors in turn translate to reduced heat sink surface area and weight for a given light output level the hb.
