Abstract
In a light emitting diode, a blue light emitting element is mounted on a base having a cup through a phosphor-containing mount so that the light emitting element is located within the cup and is mounted on the bottom of the cup through the phosphor-containing mount. The light emitting diode includes a light emitting element and a p electrode. By virtue of the above construction, blue light emitted from the light emitting element can be reflected from the lower surface of the p electrode without being radiated directly from the upper surface of the light emitting element to the outside of the light emitting diode. As a result, the blue light emitted from the light emitting element can be efficiently mixed with yellow light given off from the phosphor in the phosphor-containing mount to provide white light which is radiated to the outside of the light emitting diode with high efficiency. The white light can be perceived by a viewer to be uniformly radiated from the light radiating surface of the light emitting diode.
