Patent ID: 7942540

Claim:
A lighting module comprising: a mounting plate with at least one semiconductor light emitter coupled to the mounting plate; at least one side wall coupled to the mounting plate and surrounding the at least one semiconductor light emitter, at least one side wall comprising an area of wavelength converting material; a reflective top wall coupled to the at least one side wall, wherein the mounting plate, the at least one side wall, and the reflective top wall define a cavity that contains the at least one semiconductor light emitter and wherein light is emitted from the cavity through the at least one side wall; and a reflective element that is held within the cavity, wherein at least one of the reflective element and the at least one side wall is moveable with respect to the other to position the reflective element to block light from the at least one semiconductor light emitter from being incident on the area of wavelength converting material and to position the reflective element so that light from the at least one semiconductor light emitter is incident on the area of wavelength converting material.
