<P>PROBLEM TO BE SOLVED: To provide a light-emitting device enabling higher light output. <P>SOLUTION: The light-emitting device includes an LED chip 10, a mounting board 20 which has conductor patterns 23 and 23 for supplying power to the LED chip 10 and carries the mounted LED chip 10, a domelike optical member 60 which is fixed to the one surface side of the mounting board 20 to house the LED chip 10 between the optical member 60 and the mounting board 20, a sealing portion 50 composed of a transparent sealing resin that fills a space encircled with the optical member 60 and mounting board 20 to seal the LED chip 10, and a domelike color change member 70 which is so disposed as to encircle the optical member 60 on the one surface side of the mounting board 20. The mounting board 20 is provided with a plurality of resin pooling holes 27 between a part of one surface overlapping the mounting board 20 side edge of the optical member 60 and a part of one surface overlapping the mounting board 20 side edge of the color change member 70, where the resin pooling holes 27 pool the sealing resin leaking from the space when the optical member 60 is fixed to the mounting board 20. <P>COPYRIGHT: (C)2008,JPO&INPIT |
