Patent

CA 2539483

The invention relates to a light emitting device consisting of one or more light sources coupled to a light guide containing diffuser particles having a refractive index close to the refractive index of the core of the light guide. The diffuser particles cause a scattering of the light emitted from the light sources so that light emitted from the light emitting device has colour variation imperceptible to the human eye and small and gradual variations in intensity.

L'invention se rapporte à un dispositif émetteur de lumière constitué d'une ou de plusieurs sources de lumière couplées à un guide de lumière contenant des particules de diffusion de la lumière ayant un indice de réfraction proche de l'indice de réfraction de l'âme du guide de lumière. Les particules de diffusion de la lumière provoquent une diffusion de la lumière émise par les sources de lumière de sorte que la lumière émise par le dispositif émetteur de lumière présente une variation de couleur imperceptible à l'oeil humain ainsi que des variations graduelles faibles en intensité.
