<P>PROBLEM TO BE SOLVED: To provide a light emitting diode that can stably emit light generated by mixing stimulating light emitted from a light emitting element with a part of the stimulating light after converting the part to light having a different wavelength in omniazimuth direction, has a simple constitution, and is free from the deterioration of its structure and its light emitting characteristics caused by heat. <P>SOLUTION: This light emitting diode is composed of the light emitting element and a ceramic composite for optical conversion arranged around the light emitting element. The ceramic composite is a solidified body formed by continuously, three-dimensionally, and mutually entangling a single metal oxide and a composite metal oxide. The single metal oxide or the composite metal oxide contains a metallic element oxide which emits fluorescence. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
