Abstract (en)
[origin: WO2010113091A1] An optics device for stage lighting is disclosed. In one embodiment of the optics device, an LED chip (30) provides a plurality of sources of light (G, R, B, W). An optical conductor (32), which may be a mixing tubular (32), is superposed on the LED chip (30) to mix the light received from the plurality of sources of light (G, R, B, W). After passing through the optical conductor (32), the mixed light enters a compound parabolic concentrator (34) which is coupled to the optical conductor (32). The compound parabolic concentrator (34) collimates the light received from the optical conductor (32) such that a homogeneous pupil (90) is emitted.
