Abstract:
The LED comprises: a base having high thermal conductivity and having a mounting surface for die bonding; a printed circuit board mounted on the base and having a hole to expose a part of the mounting surface of the base and having a protruding portion projecting horizontally outward on the outer periphery of the base; an LED element mounted on the mounting surface of the base exposed in the hole of the printed circuit board; and a resin material sealing the LED element from above; wherein through-holes electrically connected to the LED element are formed at the outer periphery of the protruding portion and an external connection electrode is provided to the upper and lower surfaces of the through-holes.This LED enhances the heat dissipating effect to enable generation of high-luminance light and can also be mounted on either the upper or lower surface of a motherboard.
