Patent

CA 2757048

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). Af-ter passing through the optical conductor (32), the mixed light enters a compound parabolic concentrator (34) which is coupled to the optical conductor (32). The com-pound parabolic concentrator (34) collimates the light received from the optical conduc-tor (32) such that a homogeneous pupil (90) is emitted.

L'invention concerne un dispositif optique pour éclairage scénique. Selon un mode de réalisation du dispositif optique, une puce à DEL (30) fournit une pluralité de sources de lumière (V, R, B, B). Un conducteur optique (32), qui peut être un équipement tubulaire de mélange (32), est superposé sur la puce à DEL (30) afin de mélanger la lumière reçue depuis la pluralité de sources de lumière (V, R, B, B). Après être passé à travers le conducteur optique (32), la lumière mélangée entre dans un concentrateur parabolique composé (34) qui est couplé au conducteur optique (32). Le concentrateur parabolique composé (34) collimate la lumière reçue depuis le conducteur optique (32), de manière à ce qu'une pupille homogène (90) soit émise.
