Title (EN) COMBINED SURFACE LIGHT SOURCE DIFFUSION DEVICE
(FR) DISPOSITIF DE DIFFUSION DE SOURCE DE LUMIÈRE DE SURFACE COMBINÉE
(ZH) 组合式面光源扩散装置
Abstract:
(EN) A combined surface light source diffusion device, relating to the technical field of light source diffusion devices, and comprising an optical diffusion plate (1), wherein a light guide cover (2) is provided at the periphery of the optical diffusion plate (1); the light guide cover (2) located at the periphery of the light exit surface of the optical diffusion plate (1) is a speaker-shaped structure; an included angle between the inner wall of the speaker-shaped structure and the horizontal plane is 10-45 degrees; the distance from the light exit surface of the optical diffusion plate (1) to the end surface of the light outlet of the light guide cover (2) is 20-100 mm. The preset invention aims to provide a combined surface light source diffusion device which has a compact structure, is convenient to assemble, and achieve a good use effect. The combined surface light source diffusion device is used for light source irradiation diffusion and dodging.
(FR) L'invention concerne un dispositif de diffusion de source de lumière de surface combinée se rapportant au domaine technique des dispositifs de diffusion de source de lumière et comprenant une plaque de diffusion optique (1), un couvercle de guidage de lumière (2) étant disposé au niveau de la périphérie de la plaque de diffusion optique (1) ; le couvercle de guidage de lumière (2) situé au niveau de la périphérie de la surface de sortie de lumière de la plaque de diffusion optique (1) étant une structure en forme de haut-parleur ; un angle inclus entre la paroi interne de la structure en forme de haut-parleur et le plan horizontal étant de 10 à 45 degrés ; la distance de la surface de sortie de lumière de la plaque de diffusion optique (1) à la surface d'extrémité de la sortie de lumière du couvercle de guidage de lumière (2) étant de 20 à 100 mm. La présente invention vise à fournir un dispositif de diffusion de source de lumière de surface combinée qui présente une structure compacte, est pratique à assembler et permet d'obtenir un bon effet d'utilisation. Le dispositif de diffusion de source de lumière de surface combinée est utilisé pour la diffusion et l'éclaircissement par irradiation de source de lumière.
