Claim Text:
1. An apparatus comprising: at least one semiconductor light emitter; a base upon which the at least one semiconductor light emitter is mounted, the base comprising electrical connections for the at least one semiconductor light emitter and a heat spreader thermally coupled to the at least one semiconductor light emitter; at least one sidewall surrounding the at least one semiconductor light emitter and coupled to the base, each sidewall in the at least one sidewall has a first orientation with respect to the base, wherein the at least one sidewall comprises a wavelength converting material; and a reflective top element coupled to the at least one sidewall, the reflective top element having a second orientation with respect to the base, the second orientation being different than the first orientation, wherein the base, the at least one sidewall and the reflective top element define a chamber that contains the at least one semiconductor light emitter, and wherein light that is emitted from the chamber is emitted from each sidewall in the at least one sidewall comprising the wavelength converting material.
