Title:
REFLECTING LIGHT EMITTING DIODE
Document Type and Number:
Japanese Patent JP2004006438
Kind Code:
A
Abstract:

To improve reliability and efficiently radiate the heat generated by a light emitting device via a lead to the outside, and to prevent positioning accuracy for mounting from deteriorating and prevent a light emitting diode from tilting at the time of surface mounting, in the reflecting light emitting diode having the light emitting device and a reflecting surface opposed to each other.

At least a pair of lead terminals is formed using a metal lead frame. A pair of leads protrudes to the outside from the reflecting light emitting diode having a concave reflection frame, in which one of the leads has the light emitting device, the light emitting device is opposed to the reflecting surface of the reflector after the lead is electrically connected to the other lead via a gold wire, and transparent epoxy resin is filled in a gap between the reflector and the light-emitting device. On the pair of leads, heat resistance is reduced by at least a width larger than the width of a lead drawn into the reflection frame to improve the heat conduction.
