Abstract
Official abstract text for this publication.
A wavelength conversion device comprising a plurality of regions. Each region for absorbing radiant energy and emitting light having a characteristic dependent upon which region of the device emits the light.
First claim
Opening claim text (preview).
What is claimed is: 1. Apparatus for converting radiant energy comprising: a rotatable substrate; the rotatable substrate having a first annular band of a first color second radiant energy beam emitting material applied at a first radius and a second annular band of a different second color second radiant energy beam emitting material applied at a second radius different from the first radius; a source configured for directing a first radiant energy beam at the rotatable substra…
