Abstract
Provided are a light emitting device package, a method of manufacturing the light emitting device package, and a lighting system. The light emitting device package includes a package body, an electrode layer, a reflective layer, a nanopattern metal layer, a light emitting device, and a molding part. The electrode layer is disposed on the package body. The reflective layer is disposed over the electrode layer. The nanopattern metal layer is disposed over the reflective layer. The light emitting device is displayed over the electrode layer. The molding part is disposed over the light emitting device.
Claims21
A light emitting device package comprising:
- a package body;
- an electrode layer on the package body;
- a reflective layer on the electrode layer;
- a nanopattern metal layer on the reflective layer, wherein the nanopattern metal layer is contiguous such that the reflective layer is completely covered by the nanopattern metal layer;
- a coating layer on the nanopattern metal layer;
- a light emitting device on the electrode layer;
- and
- a molding part on the light emitting device,
- wherein the nanopattern metal layer has a size smaller than a wavelength of light emitted from the light emitting device, and the size of the nanopattern metal layer includes a diameter,
- wherein the contiguous nanopattern metal layer is disposed between a bottom surface of the light emitting device and on a top surface of the reflective layer, and
- wherein the contiguous nanopattern metal layer is disposed between the reflective layer and the coating layer.
A light emitting device package comprising:
- a package body;
- an electrode layer on the package body;
- a reflective layer on the electrode layer;
- a nanopattern metal layer on the reflective layer, wherein the nanopattern metal layer is contiguous such that the reflective layer is completely covered by the nanopattern metal layer;
- a coating layer on the nanopattern metal layer;
- a light emitting device on the electrode layer;
- and
- a molding part on the light emitting device,
- wherein the nanopattern metal layer has a cross-section including a sharp end, and
- wherein the nanopattern metal layer is contiguous such that all upper surfaces of the reflective layer are covered by the nanopattern metal layer.
