Patent ID: 8330348

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 each of said light extraction elements and each of said luminescence conversion elements forms a part of the outer surface of said multi-element light extraction and luminescence conversion layer away from said transparent layer; and wherein said light extraction elements diffuse said light from said light source and further wherein said luminescence conversion elements absorb a first spectrum of light from said light source and emit a second spectrum of light, further wherein 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 elements adjacent to one another and adjacent directly to said transparent layer.
