SIDE-VIEW LIGHT EMITTING DIODE HAVING IMPROVED SIDE-WALL REFLECTION STRUCTURE

摘要

A side-view light emitting diode having improved a sidewall reflection structure is provided to boost the light efficiency of the light emitting diode since a reflective layer deposited on an inner surface of a sidewall of the light emitting diode exhibits excellent reflectivity. A pair of lead frame(120) acts as a terminal, and a light emitting diode chip(102) is attached to a portion of the lead frame and is electrically connected thereto. A package body(110) houses the lead frames and has a concave(112) formed around the light emitting chip. A high reflective metal layer(126) is formed integrally on a sidewall(114) of the concave. A transparent encapsulant(140) is filled in the concave to encapsulate the LED chip, while forming a light emitting diode window. An insulating layer(124) is formed on a predetermined area of the lead frames so that the lead frames are insulated from the high reflective metal layer.
