APPARATUS HAVING A LIGHT SOURCE AND SOL-GEL MONOLITHIC DIFFUSER

摘要

An apparatus (40) for projecting light onto a predetermined area (84) includ es a light source (42) and a transparent element (46) disposed adjacent the light source (42). The transparent element (46) is mad e from sol-gel type glass, quartz, or other optical material. A plurality of micro-sculpted structures (50) integral in a surface of the transparent element (46) are provided which both homogenize and control directionality of light passing from the light source (42) through t he transparent element (46).
