D\u00e8s la fin du vingti\u00e8me si\u00e8cle, le concept de mat\u00e9riau diffuseur de lumi\u00e8re est propos\u00e9. Le mat\u00e9riau diffuseur de lumi\u00e8re d\u00e9signe un mat\u00e9riau qui peut non seulement laisser passer la lumi\u00e8re mais aussi la diffuser efficacement. Il peut transformer une source ponctuelle en source lin\u00e9aire ou une source lin\u00e9aire en source surfacique, et peut \u00eatre utilis\u00e9 comme mat\u00e9riau de source surfacique dans la plaque diffuseuse de lumi\u00e8re \u00e0 LED, les panneaux \u00e9lectroluminescents, les plaques guides de lumi\u00e8re, les dispositifs de r\u00e9tro\u00e9clairage des \u00e9crans \u00e0 cristaux liquides et autres \u00e9quipements.<\/font><\/span><\/span><\/span><\/span><\/span><\/p>\n

La plaque diffuseuse de lumi\u00e8re \u00e0 LED est obtenue en dispersant uniform\u00e9ment l'agent diffusant de lumi\u00e8re dans la plaque LED. Elle offre une excellente diffusion et transmission de la lumi\u00e8re, une bonne stabilit\u00e9 aux UV, et est largement utilis\u00e9e dans l'industrie des LED. Cela est d\u00fb \u00e0 la r\u00e9partition uniforme de l'agent diffusant de lumi\u00e8re dans le mat\u00e9riau. La lumi\u00e8re traverse le mat\u00e9riau de mani\u00e8re homog\u00e8ne sans exposer les billes de lampe, atteignant ainsi l'effet de diffusion optique.<\/font><\/span><\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

Principe<\/font><\/span><\/span><\/span><\/span><\/span><\/span><\/b><\/span><\/span><\/p>\n

Le principe de la diffusion de la lumi\u00e8re est le suivant : lorsque la lumi\u00e8re irradie la surface de la plaque diffuseuse de lumi\u00e8re \u00e0 LED, en raison de la diff\u00e9rence d'indice de r\u00e9fraction entre la r\u00e9sine PC et l'agent diffusant, la lumi\u00e8re subit une r\u00e9flexion similaire \u00e0 une r\u00e9flexion sp\u00e9culaire sur la surface de l'agent diffusant, et apr\u00e8s plusieurs r\u00e9flexions, l'effet de diffusion est atteint. Actuellement, la plaque diffuseuse de lumi\u00e8re \u00e0 LED suscite un vif int\u00e9r\u00eat des scientifiques nationaux et internationaux et a trouv\u00e9 des applications commerciales. Certaines entreprises renomm\u00e9es ont d\u00e9velopp\u00e9 des produits connexes et ont conquis un march\u00e9 plus large.<\/font><\/span><\/span><\/span><\/span><\/span><\/p>\n

Cependant, des probl\u00e8mes subsistent avec la plaque diffuseuse de lumi\u00e8re \u00e0 LED, le plus notable \u00e9tant le ph\u00e9nom\u00e8ne de jaunissement lors du processus de production et le co\u00fbt \u00e9lev\u00e9 des mat\u00e9riaux. Ceci est directement li\u00e9 \u00e0 l'agent diffusant choisi (incluant la combinaison globale de l'agent diffusant, du syst\u00e8me de r\u00e9sine et du syst\u00e8me auxiliaire) et au proc\u00e9d\u00e9 de m\u00e9lange utilis\u00e9. Si l'on choisit <\/font><\/span><\/span><\/span><\/span><\/span>Polymethylsilsesquioxane (Poudre Sph\u00e9rique de R\u00e9sine de Silicone)<\/span><\/span><\/span><\/span><\/span><\/a> comme un agent diffusant de type silicone, de meilleurs r\u00e9sultats peuvent \u00eatre obtenus avec une faible quantit\u00e9 d'ajout, un co\u00fbt relativement bas, mais avec des exigences de proc\u00e9d\u00e9 \u00e9lev\u00e9es. La plaque LED jaunit facilement si l'on utilise une extrudeuse monovis simple qui pr\u00e9sente des probl\u00e8mes de dispersibilit\u00e9. De plus, il faut s'assurer que la machine est nettoy\u00e9e, avec un passage altern\u00e9 d'eau et de particules transparentes. La plaque diffuseuse de lumi\u00e8re \u00e0 LED risque de jaunir \u00e0 la moindre n\u00e9gligence.<\/font><\/span><\/span><\/span><\/span><\/span><\/p>\n
