ABSTRACT

Translucent green colored opal glass was fabricated to substitute polycarbonate diffuser of LED lighting in orderto solve the durability problem. Batch materials of green colored opal glass with the composition of calcium phosphate foropacifier and iron oxide for colorant were made and melted at 1550oC. As the results, translucent green colored opal glasswas obtaind, which had excellent optical properties compare with nomal color glass for the diffuser of LED lighting, withno dazzling from direct light by high haze value over 90 % and low parallel transmittance value about 1 %. Therefore, it isconcluded that this translucent green colored opal glass can be used for the glass diffuser materials of LED lighting withhigh heat resistance and high durability to substitute polycarbonate diffuser.
