Abstract
Official abstract text for this publication.
A light source comprises a light-emitting device to emit electromagnetic radiation from an emitting surface and an optical element having a light input surface, a light output surface and side surfaces connecting the light input surface to the light output surface. The light input surface is located in the optical path of the light-emitting device, the electromagnetic radiation entering the optical element through the light input surface, and the light input surface has a concave curvature and an area being smaller than the area of the light output surface.
First claim
Opening claim text (preview).
The invention claimed is: 1. A light source, comprising: a light-emitting device to emit electromagnetic radiation from an emitting surface; and an optical element having a light input surface, a light output surface, and side surfaces connecting the light input surface to the light output surface; wherein: the entire light input surface is located in the optical path of the light-emitting device, in front of the emitting surface, so that the electromagnetic radiation enters…
