Abstract
A patterned substrate for light emitting diode includes a plurality of nodes and links protruding from a base plane of the substrate and base areas on the substrate, each pair of adjacent nodes is connected by a corresponding link, respectively. The nodes and links also can be concave nodes and concave links cutting into a surface of the substrate, each pair of adjacent concave nodes is connected by a corresponding concave link, respectively.
