LIGHT EMITTING DIODE ILLUMINATOR |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a long-life light emitting diode illuminator working with a little secular change of the light pickup efficiency and a little deterioration of its light emitting diode. <P>SOLUTION: A light emitting diode 1 is face-down-mounted on a circuit board 2 and has an emitting surface on one side, not parallel to the other side. A plate-like base 3 having a thicknesswise bored through-hole 31 is mounted on the circuit board 2 in the form of housing the diode 1 in the through-hole 31 closed at one side opening with the board 2. The other opening of the through-hole 31 is closed with a synthetic resin cover 5 containing phosphor mixed thereinto; the cover 5 being apart from the diode 1. <P>COPYRIGHT: (C)2004,JPO |
