Abstract

The present invention provides a pattern substrate structure for light emitting angle convergence and a light emitting diode device using the same. The pattern substrate structure has a plurality of enclosed geometric regions defined by at least three stripe-shaped parts on a substrate to provide the light reflection effect through the uneven surface of the substrate and thereby converge the light emitting angle of the light emitting diode element into 100˜110 degrees. Therefore, the illuminant efficiency of the light emitting diode device using the pattern substrate structure is substantially raised because of the improved directivity.
