A lighting fixture comprising a plurality of light emitting diodes disposed so as to radiate condensed light beams, apply light beams toward a condensation point, and emit light beams in red, blue and green, a control circuit for controlling the luminous intensity of each light emitting diode, a concave reflection mirror for reflecting light beams of light emitting diodes condensed onto the condensation point and radiating them after condensed or diffused, and a position changing unit for changing the relative position between the concave reflection mirror and the condensation point of the light emitting diodes.
L'invention concerne un luminaire comprenant une pluralité de diodes électroluminescentes disposées de manière à émettre des faisceaux lumineux condensés. Ce luminaire permet d'appliquer les faisceaux lumineux en direction d'un point de condensation et d'émettre des faisceaux lumineux en rouge, bleu et vert. Ce luminaire comprend également un circuit de commande permettant de commander l'intensité lumineuse de chaque diode électroluminescente, un miroir de réflexion concave destiné à réfléchir les faisceaux lumineux des diodes électroluminescentes sur le point de condensation et à les émettre après condensation ou diffusion, et enfin une unité de changement de position destinée à changer la position relative du miroir de réflexion concave et du point de condensation des diodes électroluminescentes.
