Lighting Device Having a 3D Scattering Element and Optical Extractor With Convex Output Surface

Abstract

A lighting device includes (1) one or more solid-state lighting (SSL) devices, (2) a thick, for example prism- or cylinder- or spherical- or dome-shaped scattering element, and (3) an optical extractor with a convex output surface.

1 - 24 . (canceled) 
     
     
         25 . A lighting device comprising:
 a light-emitting element (LEE) configured to provide light;   a conversion element forming an input interface at points of contact with the LEE, the input interface having a first dimension, the scattering element having a second dimension being orthogonal to the first dimension, the second dimension being 1-10 times the size of the first dimension, the conversion element comprising a phosphor and a transparent material, the phosphor configured to convert received light into converted light, the conversion element having an outer surface configured to output at least a portion of light received from the conversion element.   
     
     
         26 . The lighting device of  claim 25  further comprising a transparent extractor in contact with the outer surface of the conversion element.
