Abstract
Disclosed are a light emitting device package and a light unit having the same. The light emitting device package includes a ceramic substrate; a light emitting device on the ceramic substrate; a first light-transmissive resin layer on the ceramic substrate to cover the light emitting device; and a phosphor layer on the first light-transmissive resin layer.
Claims20
A light emitting device package comprising:
- a ceramic substrate;
- a semiconductor light emitting device disposed on a top surface of the ceramic substrate;
- a first light-transmissive resin layer disposed on the top surface of the ceramic substrate and a top surface of the semiconductor light emitting device to cover the semiconductor light emitting device;
- a second light-transmissive resin layer disposed on a top surface of the first light-transmissive resin layer;
- and
- a phosphor layer including a phosphor material between the top surface of the first light-transmissive resin layer and a lower surface of the second light-transmissive resin layer,
- wherein the first light-transmissive resin layer has a same width as a width of the ceramic substrate,
- wherein the first and second light-transmissive resin layers include a convex portion protruding upward of the semiconductor light emitting device,
- wherein the first light-transmissive resin layer physically contacts a surface of the semiconductor light emitting device,
- wherein the lower surface of the second light-transmissive resin layer physically contacts a top surface of the phosphor layer,
- wherein the first light-transmissive resin layer includes a planar top surface substantially parallel to the top surface of the ceramic substrate on a periphery of the convex portion of the first light-transmissive resin layer,
- wherein the second light-transmissive resin layer includes a planar top surface substantially parallel to the top surface of the ceramic substrate on a periphery of the convex portion of the second light-transmissive resin layer,
- wherein a lower surface of the phosphor layer is spaced apart from the top surface of the ceramic substrate, and
- wherein the first and second light-transmissive resin layers do not contain any phosphor material.
