Abstract
A light emitting diode includes two lead-frames, one or a plurality of light emitting chip, a casing, and a packaging colloid; the casing comprised of two pairs of a first and a second side units to surround a compartment; the first side unit being higher than the second side unit; the packaging colloid being received in the compartment; and the packaging colloid protruding from the casing to indicate a convex so to change angle of incidence of the light after leaving the packaging colloid and to improve light use efficiency and light emitting angle.
