Abstract
Translucent green colored opal glass was fabricated to substitute polycarbonate diffuser of LED lighting in order to solve the durability problem. Batch materials of green colored opal glass with the composition of calcium phosphate for opacifier and iron oxide for colorant were made and melted at $1550^{\circ}C$. As the results, translucent green colored opal glass was obtaind, which had excellent optical properties compare with nomal color glass for the diffuser of LED lighting, with no dazzling from direct light by high haze value over 90 % and low parallel transmittance value about 1 %. Therefore, it is concluded that this translucent green colored opal glass can be used for the glass diffuser materials of LED lighting with high heat resistance and high durability to substitute polycarbonate diffuser.
