Abstract
Disclosed is a light emitting device and a method of manufacturing the same. The light emitting device includes a body, a first electrode installed in the body and a second electrode separated from the first electrode, a light emitting chip formed on one of the first and second electrodes, and electrically connected to the first and second electrodes, and a protective cap projecting between the first and second electrodes.
Claims20
A light emitting device comprising:
- a body having a length in a first direction and a width in a second direction;
- a first electrode in the body and a second electrode separated from the first electrode;
- a light emitting chip coupled to at least one of the first or second electrode and electrically connected to the first and second electrodes;
- and
- a protector that extends in the first direction between the first and second electrodes,
- wherein a top surface of the protector is higher than respective top surfaces of the first and second electrodes in a third direction perpendicular to the first and second directions,
- wherein a width of a bottom portion of the protector is greater than a width of the top surface of the protector,
- wherein the protector comprises a region, wherein a width of the region gradually increases,
- wherein a width of a middle portion of the protector is less than both the width of the top surface of the protector and the width of the bottom portion of the protector,
- wherein the protector comprises at least two edge portions contacting the body, and a center portion disposed between the at least two edge portions in the first direction, and
- wherein a width of the at least two edge portions in the second direction is larger than a width of the center portion in the second direction.

A light emitting device comprising:
- a body;
- first and second electrodes, each including at least one coupling pin protruding from a lateral surface to be coupled with a material of the body in a concavo-convex structure, wherein the first and second electrodes and respective ones of the coupling pins have a substantially T-shape section;
- a protector between the first and second electrodes;
- and
- a light emitting chip coupled to at least one of the first electrode or the second electrode,
- wherein the first or second electrode that is coupled to the light emitting chip has a surface that includes a guide groove,
- wherein the guide groove is on an outer peripheral portion of the light emitting chip,
- wherein the protector comprises a region, wherein a width of the region gradually increases,
- wherein a width of a middle portion of the protector is less than both a width of a top surface of the protector and a width of the bottom portion of the protector,
- wherein the protector comprises a protrusion protruding between the first and second electrodes, and
- wherein the protrusion covers a gap between the first and second electrodes, and surrounds both lateral surfaces and at least a portion of top surfaces of the first and second electrodes.
