Light source device using led, and method of producing same |
摘要 |
A light source apparatus which is improved in the efficiency of light emission thus to increase the operating life and the mechanical strength and a method of producing the same are provided. The light source apparatus 1 comprises a radiator plate 3 having thermally conductive properties, an insulating member 4 coupled to at least one side of the radiator plate 3 and having a through hole 6 provided in the side thereof facing the radiator plate 3, an LED chip 2 installed and thermally coupled to an exposed portion of the radiator plate 3 facing the through hole 6, an extension 4a inwardly projecting at the hole 6 from the radiator plate 3 end of the insulating member 4, a wiring pattern 8 provided on the insulating member 4 and electrically isolated by the insulating member 4 from the radiator plate 3, bonding wires 9 electrically connecting between portions of the wiring pattern 8 extended to the extension 4a and the electrodes of the LED chip 2, and a light-transmissive sealing material 10 filled in the through hole 6 for entirely encapsulating the LED chip 2 and the bonding wires 9. |
