  • Publication number: 20150340580
    Abstract: Disclosed are a light emitting device. The light emitting device include first and second lead frames, a first body on the first and second lead frames and including an open region, a second body on the first body and including a first opening, a light emitting chip on the opening region, and a transmissive layer on the light emitting chip. The first body and the second body are formed of a resin material. A top surface of the first body is located at a position lower than a position of a top surface of the light emitting chip. The second body includes a bottom surface located at a position lower than the position of the top surface of the light emitting chip. The first body comprises an inclined part around the light emitting chip. The first body includes a reflectance material and the second body includes a transmissive material.
