Method for manufacturing flat light source, involves providing surface with translucent material with local slots, where local slots are embossed with field of rigid interconnected mandrels into surface

摘要

The method involves providing a surface (8) with a translucent material (3) with local slots (10), where the local slots are embossed with field of rigid interconnected mandrels (12) into the surface. The field is a two-dimensional field. The mandrels in each dimension of the field are arranged in a fixed grid. The mandrels are parts of an embossing roller. Independent claims are also included for the following: (1) an embossing tool for carrying out a flat light source manufacturing method; and (2) a light source.
