An LED collimation optics module (16) providing an isolation fitting and luminaire (10) using the same are dis-closed. 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). A sleeve is connected to the LED chip (30) and positioned about the optical conductor (32) such that an an-nulus (102) is located therebetween. After passing through the optical conductor (32), the mixed light enters a compound parabol-ic 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 is emitted.

L'invention concerne un module optique de collimation à DEL (16) fournissant un raccord isolant et un luminaire (10) faisant intervenir ledit module. 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). Un manchon est raccordé à la puce à DEL (30) et positionné autour du conducteur optique (32) de sorte qu'un espace annulaire (102) soit situé entre le manchon et le conducteur. 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) façon qu'une pupille homogène soit émise.
