Title (EN) OPTICAL DIFFUSER HAVING FRIT BASED COATING WITH INORGANIC LIGHT DIFFUSING PIGMENTS WITH VARIABLE PARTICLE SIZE THEREIN
(FR) DIFFUSEUR OPTIQUE POURVU D'UN REVÊTEMENT FRITTÉ AVEC DES PIGMENTS INORGANIQUES DE DIFFUSION DE LA LUMIÈRE DE DIMENSION DE PARTICULE VARIABLE
Abstract:
(EN) A diffuser is provided that includes a glass substrate with a diffusing coating thereon. The diffusing coating may include one or more layers. In certain example embodiments, the diffusing coating comprises inorganic pigments therein for light diffusing purposes, and the inorganic pigments are sized so as to permit a diffuser having a combination of high visible transmission and good diffusion qualities to be realized. In certain example embodiments, the diffusing coating may be of or include a frit with the inorganic pigments therein.
(FR) L'invention concerne un diffuseur comprenant un substrat en verre recouvert d'un revêtement de diffusion. Le revêtement de diffusion peut comprendre une ou plusieurs couches. Dans certains modes de réalisation, à titre d'exemple, le revêtement de diffusion comprend des pigments inorganiques utilisés pour diffuser de la lumière, et les pigments inorganiques ont une dimension permettant d'obtenir un diffuseur combinant des qualités de transmission visible élevée et de bonne diffusion. Dans certains modes de réalisation, à titre d'exemple, le revêtement de diffusion peut être fritté ou comprendre une fritte contenant les pigments inorganiques.
