Abstract

Le dispositif d'éclairage comporte au moins un émetteur de lumière (20) à diode électroluminescente destiné à émettre de la lumière blanche. Le dispositif comporte aussi des moyens de répartition (22) pour augmenter la surface d'émission de lumière. Lesdits moyens de répartition sont destinés à recevoir au moins un faisceau lumineux incident (23) fourni par ledit émetteur de lumière à diode électroluminescente et à répartir ledit faisceau (21) en faisceaux sortants (24) vers une zone (25) de diffusion de lumière. Le répartiteur permet un mélange efficace de lumière et de couleurs lorsque le dispositif comporte des émetteurs de lumières rouge, et bleue ou verte.

Figure imgaf001
The illumination device comprises at least one light emitting diode emitter (20) for emitting white light. The device also comprises distribution means (22) for increasing the light emission surface. Said distribution means are adapted to receive at least one incident light beam (23) provided by said light-emitting diode light emitter and to distribute said beam (21) in outgoing beams (24) to a light scattering zone (25); . The splitter allows for efficient mixing of light and color when the device has red, blue or green light emitters.
