Light emitting apparatus
DCFirst Claim
1. A light emitting apparatus comprising:
- a substrate;
a light emitting device on the substrate; and
a lens on the light emitting device,wherein the lens includes a center portion, a peripheral portion surrounding the center portion and a side portion surrounding the peripheral portion and having an outer side surface,wherein the center portion of the lens has a first top surface with a first recess and a first bottom surface with a second recess, the first and second recesses opposite to each other,wherein the first recess has an inwardly-concave curvature shape,wherein the first recess has a width greater than that of the second recess,wherein a thickness of the outer side surface of the side portion is smaller than a depth of the second recess of the center portion, andwherein the peripheral portion of the lens has a second rounded-top surface extending from the first top surface to the side portion, andwherein the second rounded-top surface of the peripheral portion has a continuing surface between the center portion and the side portion.

Abstract
Provided is a light emitting apparatus. The light emitting apparatus includes a substrate; a light emitting device on the substrate; a fluorescent layer formed on the substrate and the light emitting device to surround the light emitting device; an encapsulant resin layer formed on the substrate and the fluorescent layer to surround the fluorescent layer; and a lens disposed on the light emitting device and supported by the substrate, wherein the lens includes a lens body having a first recess formed at a center of a top surface of the lens body and a second recess formed at a center of a bottom surface of the lens body, and a lens supporter provided at the bottom surface of the lens body to support the lens body such that the lens body is spaced apart from the substrate.
