Abstract

Provided is a light emitting device package. The light emitting device package comprises a body, a heat diffusing member, a light emitting diode (LED), and a buffer layer. A cavity with an opened topside is formed in the body. The heat dissipation member is disposed between a bottom surface of the cavity and a lower surface of the body. The LED is disposed on one of an electrode disposed on the bottom surface of the cavity. The buffer layer is disposed between the heat dissipation member and a pad and has a thickness thinner than the thickness of the heat dissipation member.The light emitting device package provided in the invention can increase the heat dissipation efficiency.

Description

technical field [0001] The present disclosure relates to a light emitting device package and an ultraviolet lamp having the light emitting device package. Background technique [0002] A light emitting diode (LED) can be used as a light source, and it can be formed of a compound semiconductor material such as a GaAs-containing material, an AlGaAs-containing material, a GaN-containing material, an InGaN-containing material, and an InGaAlP-containing material . [0003] Light emitting device packages capable of emitting light of various colors can be manufactured by packaging these LEDs. The light emitting device package is used as a light source for various devices such as lighting display devices, character display devices, and image display devices. [0004] In particular, ultraviolet (UV) LEDs are capable of emitting light with a wavelength of 245nm to 405nm. For example, short-wavelength light from UV LEDs can be used for sterilization or purification, while long-wavel...
