摘要： A shaped light extraction luminaire to gather light from an organic light emitting diode (OLED). Specifically, an inverted and truncated pyramid structure having a recessed area configured to receive an OLED is provided. The luminaire is structured to increase the light emission of the OLED by capturing light emissions that would typically be lost by absorption within the OLED. The luminaire includes angled sides having a reflective material disposed thereon. The luminaire increases the light output of the OLED such that it may be implemented in area lighting applications. Further, an array comprising a plurality of recessed areas and a plurality of angled sides for each of the recessed areas may be implemented.
