Abstract
A method of making a light source includes the steps of forming a first optical component having a phosphor material in fixed relation to a first multilayer interference reflector, providing a second optical component having an LED capable of emitting light that excites the phosphor material, and positioning the first optical component to receive emitted light from the second optical component. Corresponding articles are also disclosed.
