Patent ID: 7193365

Claim:
A high-intensity light emitting diode comprising: a substrate; a pair of electrodes provided on said substrate; a light emitting element mounted on said substrate and connected electrically with said electrodes, the light emitting element having a light-projecting surface; a transparent cover comprising a cuboid resin formed on said substrate for sealing said electrodes and said light emitting element; and a concave and convex shaped light scattering part provided on a flat surface of said cover facing toward the light-projecting surface of the light emitting element; wherein said light scattering part includes a plurality of concave and convex portions formed on the flat surface of the cover, wherein a depth and an oblique angle of each of the concave and convex portions are un-uniformly formed with respect to each other so that light scatters in a wide-angle direction at the light scattering part, wherein the depth of each of the concave and convex portions of the light scattering part is 4 μm or more, and wherein the oblique angle made by each of the concave and convex portions of the light scattering part is in a range of 1 to 45 degrees.
