Patent number: 8268651Abstract: The invention provides a side-view LED having an LED window opened to a side to emit light sideward. A pair of lead frames each act as a terminal. An LED chip is attached to a portion of the lead frame and electrically connected thereto. A package body houses the lead frames and has a concave formed around the LED chip. Also, a high reflective metal layer is formed integrally on a wall of the concave. A transparent encapsulant is filled in the concave to encapsulate the LED chip, while forming the LED window. In addition, an insulating layer is formed on a predetermined area of the lead frames so that the lead frames are insulated from the high reflective metal layer. The side-view LED of the invention enhances light efficiency and heat release efficiency with an improved side-wall reflection structure.Type: GrantFiled: November 13, 2009Date of Patent: September 18, 2012Assignee: Samsung Electronics Co., Ltd.Inventor: Hong Min Kim
