Title
(EN) LED LIGHT FIXTURE WITH BACKGROUND LIGHTING USING CONTROLLED INBETWEEN DIFFUSED LIGHT GROUP
(FR) LUMINAIRE À DIODES ÉLECTROLUMINESCENTES À RÉTROÉCLAIRAGE UTILISANT UN GROUPE DE LUMIÈRES DIFFUSES INTERMÉDIAIRE COMMANDÉ
Abstract
(EN) An illumination device with a number of light sources arranged in at least two groups of light sources that are individually controllable. The first group of light sources (203) have light collectors (209) such as internal reflection (TIR) lenses, mixers or other lenses placed over them to collect and convert light of the light sources into a number of light source beams. The second group of light sources (205) pass light through diffusing areas (215) of a diffuser (213) in the form of a diffusion cover included in the lamp housing to diffuse the light and create a background light for the first group of light sources. The light from the first group of light sources pass through non diffusing regions (211) of the diffuser cover without the light being diffused. The second group of light sources are interleaved with the first group by the diffuser having one or several diffusion areas between non diffusion areas. By controlling both groups of light sources based on the same target color the dotted look of led light sources can be removed or by controlling the two groups of light sources based on two different colors light effects can be obtained. The illumination device can be included in a moving head light source with a base, a yoke connected rotably to the base and the head connected rotatably to the head.
(FR) L'invention porte sur un dispositif d'éclairage, comportant un certain nombre de sources de lumière disposées en au moins deux groupes de sources de lumière qui peuvent être commandés de façon individuelle. Le premier groupe de sources de lumière (203) a des collecteurs de lumière (209) tels que des lentilles à réflexion interne (TIR), des mélangeurs ou d'autres lentilles disposées sur celles-ci pour collecter et convertir de la lumière des sources de lumière en un certain nombre de faisceaux de sources de lumière. Le second groupe de sources de lumière (205) fait passer de la lumière à travers des zones de diffusion (215) d'un diffuseur (213) sous la forme d'un revêtement de diffusion inclus dans le boîtier de lampe afin de diffuser la lumière et de créer un rétroéclairage pour le premier groupe de sources de lumière. La lumière provenant du premier groupe de sources de lumière traverse des régions de non-diffusion (211) du revêtement de diffuseur sans que la lumière soit diffusée. Le second groupe de sources de lumière est entrelacé avec le premier groupe par le fait que le diffuseur a une ou plusieurs zones de diffusion entre des zones de non-diffusion. Grâce à la commande des deux groupes de sources de lumière sur la base de la même couleur cible, l'aspect à points de sources de lumière à diodes électroluminescentes peut être éliminé, ou, grâce à la commande des deux groupes de sources de lumière sur la base de deux couleurs différentes, des effets de lumière peuvent être obtenus. Le dispositif d'éclairage peut être inclus dans une source de lumière à tête mobile avec une base, une fourche reliée de façon à pouvoir tourner à la base et la tête reliée de façon à pouvoir tourner à la fourche.
