Abstract
A method for manufacturing microlens light guide, which mainly includes forming patterns, in a concave or convex shape, on a plastic or wax mold substrate by mechanical processing or non-traditional processing, plasticizing the patterns to microlens patterns, as a master mold for later use, by thermal flow, electroforming to make mold core for later use, and finally injection molding to make microlens light guide.
Claims3
A method for manufacturing microlens light guide, including:
- forming dot patterns on a flat substrate;
- baking said flat substrate to plasticize said dot patterns to microlens patterns through thermal flow;
- electroforming to make said flat substrate as a processing mold;
- and
- making said microlens light guide by use of said processing mold.
