ABSTRACT:
A diffuser is provided in an illumination system, where the diffuser is capable of blocking significant amounts of ultraviolet (UV) radiation. In certain example embodiments of this invention, the diffuser includes a glass substrate which supports a UV coating(s) that blocks significant amounts of UV radiation thereby reducing the amount of UV radiation which can makes its way through the diffuser. In certain example embodiments, the coating may including particulate so that the coating may both diffuse visible light and perform UV blocking.
