Patent number: 9401467Abstract: Provided are a light emitting device (LED) package and a lighting system including the same. The LED package comprises a package body comprising a recess in an upper portion thereof, and an LED chip provided in the recess of the package body. The LED package has a structure in which the LED chip may be buried into a recess formed on a planar surface on the upper portion of the package body such that a bottom surface of the recess lies below the planar surface. Thus, a main path through which heat generated from the LED chip is transmitted may be expanded from a bottom surface of the LED chip up to a lateral surface thereof to widen a dissipation area, thereby improving thermal emission efficiency.Type: GrantFiled: April 27, 2010Date of Patent: July 26, 2016Assignee: LG INNOTEK CO., LTD.Inventor: Kyoung Woo Jo
