Abstract
A light emitting device according to an embodiment includes a body having a recess; a light emitting chip disposed in the recess; and a first dampproof layer sealing the light emitting chip and extended from a surface of the light emitting chip to a bottom of the recess, wherein the light emitting chip includes a wavelength range of 100 nm to 280 nm, and the first dampproof layer includes a fluororesin-based material.
Claims20
A light emitting device comprising:
- a body including a first outer side, a second outer side adjacent to the first outer side, a third outer side adjacent to the second outer side, and a fourth outer side adjacent to the third outer side;
- a first metal layer disposed on a central region of the body;
- an extension portion extending from the first metal layer toward the fourth outer side;
- a light emitting chip disposed on the first metal layer;
- a second metal layer adjacent to the first outer side and the second outer side, wherein the second metal layer includes a first portion disposed between the first outer side and the first metal layer and a second portion disposed between the second outer side and the first metal layer;
- a third metal layer adjacent to the third outer side and the fourth outer side, wherein the third metal layer includes a third portion disposed between the third outer side and the first metal layer and a fourth portion disposed between the fourth outer side and the first metal layer;
- and
- a fourth metal layer disposed between the first portion and the fourth outer side and disposed between the fourth portion and the first outer side,
- wherein the extension portion, the fourth metal layer and the fourth portion overlap in a first direction parallel to the fourth outer side,
- wherein the first portion and the third portion overlap in a second direction parallel to the fourth outer side, the second direction being parallel to the first direction, and
- wherein the fourth metal layer is not overlapped with the light emitting chip in the first direction parallel to the fourth outer side.

A light emitting device comprising:
- a body including a first outer side and a third outer side extending in a first direction, a second outer side and a fourth outer side extending in a second direction orthogonal to the first direction, an upper surface and a lower surface;
- a recess recessed in a downward direction from the upper surface of the body, wherein the recess includes a first inner side and a third inner side extending in the first direction, a second inner side and a fourth inner side extending in the second direction, and a bottom surface;
- a light emitting chip disposed on the bottom surface of the recess;
- and
- a first sub-recess and a second sub-recess recessed from the bottom surface of the recess toward the lower surface of the body,
- wherein the first sub-recess is disposed closer to the first inner side than the light emitting chip, and the first sub-recess is closer to the fourth inner side than the light emitting chip,
- wherein the second sub-recess is disposed closer to the second inner side than the light emitting chip, and the second sub-recess is disposed closer to the third inner side than the light emitting chip, and
- wherein a first straight line passes through the first sub-recess, passes through the second sub-recess and passes through a first intersection point where the first outer side meets the fourth outer side.
