CA 2757196

An LED collimation optics module (16) and luminaire (10) using the same, and optics device for stage lighting are disclosed. In one embodiment of the LED collimation optics module (16), an LED chip (30) provides a plurality of sources of light (G, R, B, W). An optical conductor (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.

L'invention concerne un module optique de collimation à DEL (16) et un luminaire (10) faisant intervenir ledit module, ainsi qu'un dispositif optique d'éclairage de scène. Dans un mode de réalisation dudit module optique de collimation à DEL (16), une puce à DEL (30) fournit une pluralité de sources lumineuses (G, R, B, W). Un conducteur optique (32) est superposé sur la puce à DEL (30) pour mélanger la lumière reçue à partir de la pluralité de sources lumineuses (G, R, B, W). Après être passée par le conducteur optique (32), la lumière mélangée entre dans un concentrateur parabolique composite (34) qui est couplé au conducteur optique (32). Le concentrateur parabolique composite (34) assure la collimation de la lumière reçue à partir du conducteur optique (32) de façon qu'une pupille homogène (90) soit émise.
