SURFACE MOUNT LIGHT EMITTING DIODE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a surface mount LED suitable for mounting in a vehicle and having excellent heat dissipation characteristics and reliability.

SOLUTION: The surface mount light emitting diode comprises a recess 1d having a circular bottom 1b and a conical light reflecting side face 1c and formed on one surface 1a of a package 1 molded in a substantially cubic shape by injection molding or press forming a metal core material of high heat conductive Mg, Al, Cu or the like. A longitudinal slit 1f is formed from the one surface 1a to the back-to-back surface 1e with the surface 1a, and an insulating member 2 is filled in the slit. The LED element 3 with a bump of the light emitting element is connected to both electrode surfaces of the bottom 1b by bridging the member 2 by FC bonding. An underfill resin 4 is filled in a gap between the LED element 3 and the bottom 1b. A cover plate 5 made of a transparent glass or a resin is connected to the upper surface 1a of the package 1 to seal the interior with air as a medium of the light.
