Abstract
A light source apparatus having a radiator plate having thermally conductive properties and an insulating member coupled to at least one side of the radiator plate having a through hole provided in a side thereof facing the radiator plate. The light source apparatus further including a LED chip installed and thermally coupled to an exposed portion of the radiator plate facing the through hole, an extension inwardly projecting at the through hole from the radiator plate end of the insulating member, and a wiring pattern provided on the insulating member electrically isolated by the insulating member from the radiator plate. The light source apparatus also including bonding wires electrically connecting portions of the wiring pattern on the extension and the electrodes of the LED chip, and a light-transmissive sealing material filling the through hole for entirely encapsulating the LED chip and the bonding wires.
