ABSTRACT:
A light-emitting diode includes: a light-transmitting substrate; a light-emitting element mounted on the upper surface of the light-transmitting substrate; and a light-transmitting resin that seals the light-emitting element. The outer surface of the light-transmitting resin is covered with a reflecting layer formed from a silver or aluminum thin film. The light emitted from the light-emitting element is reflected from the reflecting layer, and the reflected light is guided out from the lower surface of the light-transmitting substrate in an efficient manner with minimum wastage of light intensity, and thus, high luminance light can be emitted.
