Patent ID: 7834546

Claim:
An electroluminescent apparatus, comprising: a light source comprising a transparent layer capable of at least partially transmitting light out from said light source; and a multi-element light extraction and luminescence conversion layer disposed over said transparent layer and on the exterior of said light source, said multi-element light extraction and luminescence conversion layer comprising a plurality of light extraction elements and a plurality of luminescence conversion elements, wherein: said light extraction elements diffuse said light from said light source, said luminescence conversion elements absorb a first spectrum of light from said light source and emit a second spectrum of light, said non absorbed first spectrum of light, said second spectrum of light and said diffused light output due to said light extraction elements form a total output spectrum of light for said electroluminescent apparatus, said light extraction elements and luminescence conversion elements are adjacent to one another and directly adjacent to said transparent layer, and the plurality of luminescence conversion elements and plurality of light extraction elements are arranged in an alternating pattern, a meshed pattern or such that the plurality of luminescence conversion elements are conically sectioned.
