Abstract
is attached on surface of plastic preform or a cavity of a mold core of a mold. By plastic molding, the plastic preform is heated, pressured and cast into a molded fluorescent plastic lens with a fluorescent surface. Thus the molded fluorescent plastic lens not only has shape and optical properties of the molded forming lens, but also has fluorescent properties from a fluorescent surface layer formed by fluorescent material inserted into the plastic. Thus the produced molded fluorescent plastic lens is applied to road reflectors, white light LED or other optical elements for use.
