1. A light source, comprising:
- an LED that emits excitation light;
a layer of phosphor material positioned to receive the excitation light, the phosphor material emitting visible light when illuminated with the excitation light; and
a first non-planar flexible multilayer reflector that reflects the excitation light and transmits visible light, the non-planar flexible multilayer reflector being positioned to reflect LED light onto the phosphor material.

Abstract
A light source including an LED that emits excitation light, a layer a phosphor material positioned to receive the excitation light, the phosphor material emitting visible light when illuminated with the excitation light, and a first non-planar flexible multilayer reflector that reflects the excitation light and transmits visible light. The non-planar flexible multilayer reflector is positioned to reflect LED light onto the phosphor material.
