<P>PROBLEM TO BE SOLVED: To precipitate almost all phosphor powders in a pasty resin onto a bottom portion in a case in a short time and to remove bubbles included in the resin in a short time and substantially completely. <P>SOLUTION: A lead frame 3 to which a light-emitting diode 2 is bonded is accommodated in a bottom portion within a case 1 and a pasty resin 4 with phosphor powers mixed therein is filled between the lead frame 3 and the case 1. The case 1 is rotated in a perpendicular direction to cause a centrifugal force to act on the resin 4 and with a lapse of a required time after the start of rotation, the periphery of the case 1 is gradually evacuated. The resin 4 is thereafter cured. <P>COPYRIGHT: (C)2009,JPO&INPIT |
