Abstract (en)
[origin: WO2012004760A1] An optical zoom assembly (16) for a non- imaging illumination application and luminaire (10) using the same are disclosed. In one embodiment, a light emitting diode chip (40) provides light to an optical conductor (46 ) having a plurality of transmission paths that enable the mixing of the light. A collector lens (48) is disposed serially and coaxially with the optical conductor to the mixed light received from the optical conductor. A zoom subassembly (50), including one or more optical lenses located serially and coaxially with the central optical axis, is movable coaxially with respect to the collector lens to create a beam of light having a divergence profile controlled by a variable spacing between the one or more optical lenses and the collector lens.
