Abstract
Official abstract text for this publication.
An embodiment relates to a light emitting module. A light emitting module according to an embodiment includes a light source unit including a light emitting device; a body including a lower portion on which the light source unit is arranged, a wall portion arranged on the lower portion and configured to surround the light source unit, and an upper portion arranged on the wall portion; an optical member arranged on the light source unit to transmit light from the light emitting device; and an adhesive member arranged between the wall portion of the body and the optical member to couple the body and the optical member, wherein the upper portion of the body is arranged between the light emitting device and the adhesive member.
First claim
Opening claim text (preview).
The invention claimed is: 1. A light emitting module, comprising: a light source unit comprising a light emitting device; a body comprising a lower portion in which the light source unit is disposed, a wall portion disposed on the lower portion and surrounding the light source unit, and an upper portion including a top surface of the wall portion; an optical member disposed on the light source unit and transmitting light from the light emitting device; and an adhesive member disposed between the top surface of the wall portion of the body and the optical member, wherein the upper portion of the body and the optical member come in contact with each other, or a gap between the upper portion of the body and the optical member is formed, wherein the top surface of the wall portion of the body comprises an inner portion and an outer portion, wherein a length between the inner portion of the top surface of the wall portion of the body and a bottom surface of the body is longer than that between the outer portion and the bottom surface of the body, wherein the adhesive member is in contact with the outer portion of the top surface of the wall portion and the optical member, wherein the light emitting device emits UV rays having a wavelength of 200 nm-405 nm, and wherein a lateral side of the optical member is flush with an outer lateral side of the wall portion of the body. 2. The light emitting module of claim 1 , wherein: the optical member comprises a top surface and a bottom surface, and the bottom surface of the optical member comes in contact with the inner portion of the top surface of the wall portion of the body. 3. The light emitting module of claim 1 , wherein at least one of the lower portion, the wall portion, and the upper portion is a ceramic board comprising ceramic layers of a single layer or a multi-layer. 4. The light emitting module of claim 1 , wherein: the optical member comprises a top surface and a bottom surface, and the bottom surface of the optical member is spaced apart from the inner portion of the top surface of the wall portion of the body at a predetermined interval. 5. The light emitting module of claim 1 , wherein a length of a side of the optical member is equal to that of a side of the bottom surface of the body. 6. The light emitting module of claim 1 , wherein a side of the adhesive member is disposed between a side of the optical member and a side of the wall portion of the body and is exposed to an outside.
