Abstract:
1. An apparatus comprising: at least one semiconductor light emitter; a base upon which the at least one semiconductor light emitter is mounted; at least one sidewall surrounding the at least one semiconductor light emitter and coupled to the base; a top element coupled to the at least one sidewall, wherein the base, the at least one sidewall and the top element define a chamber that contains the at least one semiconductor light emitter, wherein the top element is reflective and wherein light produced by the at least one semiconductor light emitter is emitted through the at least one sidewall; and an adjustable wavelength converting element coupled to the chamber, the adjustable wavelength converting element being configured to adjust a surface area that is exposed to light emitted by the at least one semiconductor light emitter in the chamber to alter optical properties of the chamber.
