產品: 擴散板
擴散板在原理上只區分為截止擴散板及通過擴散板,截止擴散一般用在只需肉眼可見的影像,例如冷陰極射線管(普通的顯像管電視),液晶電視背光源,電影銀幕......等等,通過擴散相對陌生很多一般最常見的有照相機的閃光燈,手朮室的無影燈,拍電影用的投光燈....等等, 在截止擴散中它需要的擴散率不需很大,因光線的密度太大為了讓光使能連接變成影給讓肉眼可見就達到效果,它的製作上均用塗層來處理,顯像管里塗的就是電激發光稀土,液晶電視用的擴散膜就塗了白色物質,大屏幕的液晶電視它採用直照式設計它的擴散板里也加入80%以上的所謂擴散劑,這些擴散劑中也是加入白色物質再經化學交聯作用使它變成熱固化物質,在下一個工序中跟原來的熱可塑材料連結壓成片狀物而成,電影銀幕上為了反射效果更加好所以塗上玻璃珠再經鍍膜加上熱熔膠轉印到帆布上,一般民用照明也有用這種工藝流程,例如毛玻燈泡,吸頂燈罩,缺點就是光損超過55%,因此不適合LED照明使用 但通過擴散學問大很多,它不止光要均勻還要降低光損一般都採用費更斯透鏡處理,當你看到燈具上一圈圈的環狀玻璃燈罩就是費更斯透鏡,也叫透鏡擴散所以通過擴散時眼睛還是可以看到燈泡發出的眩光,因此費更斯透鏡在用途上並不很合適用於民用LED照明用途,只適特定場所使用 在未來的生活中節能是首要課題,經金融海嘯后這個問題更加關注,因能耗太大導致石油大漲,原材料因運輸成本提高也跟隨水漲船高,我公司早在八年前就着手研發各類用途的光擴散板,其中大部分集中在LED擴散中,最適合於LED照明用它分為物理擴散及光學擴散,光學擴散中又分為衍射擴散及柱鏡擴散,物理擴散又分發光擴散及散射擴散
