摘要：
A method of molding an illumination device using an open mold is provided. The method allows for the addition of light extraction structures to a prefabricated light guide using a curable material. A mold containing the extraction structures is first provided. Curable molding material and the prefabricated light guide are placed into the mold, and an overlay comprising light extraction structures is cured onto the light guide, providing a functional illumination device.
