CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of Korean Patent Application No. 10-2012-0026068 filed on Mar. 14, 2012, and No. 10-2013-0000946 on Jan. 4, 2013 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The inventive concept relates to a light emitting element package and a method of manufacturing the same.[0004]2. Description of the Related Art[0005]A light emitting diode (LED) is a type of a luminous element (or light emitting element) capable of implementing light in various colors by forming a light emission source through a PN junction in a compound semiconductor.[0006]The uses of LEDs have extended from a signal light to general illumination devices, and in order to emit a larger quantity of light, LEDs have tended to have enhanced light efficiency and larger sizes. Meanwhile, as the general purposes of LEDs have extend...

AI Technical Summary

Benefits of technology

[0009]In the art, a light emitting element package and a manufacturing method thereof capable of maximizing a degree of freedom in a design of an illumination device by implementing an ultra-small package are required.

Problems solved by technology

However, in case of a premolded structure such as a conventional light emitting element package structure in which an LED is attached to a package body or in the case of a package structure in which an LED chip is attached to a ceramic substrate, or the like, there is a limitation in reducing a size, resulting in a limitation in a degree of freedom available in the designing of an illumination device.

Here, heat generated by the light emitting element is dissipated outwardly through the circuit board, and in this case, if heat generated by the light emitting element is not smoothly dissipated outwardly, reliability of the light emitting element package may be degraded, or the like.
