Light emitting apparatus
First Claim
1. A lens comprising:
- a lens body having a convex top surface, a bottom surface, and a lateral surface between the convex top surface and the bottom surface, the bottom surface including a recessed part at a central portion thereof, the lateral surface being perpendicular to the bottom surface; and
a plurality of lens supporters at the bottom surface of the lens body,wherein a maximum thickness (f) of the lateral surface ranges from about 1.8 mm to about 2 mm,wherein a ratio of a maximum depth (b) of the recessed part to a maximum thickness (h) of the lens body ranges from about 0.5 to about 0.75, andwherein a ratio of a maximum width (d) of the recessed part to a maximum width (j) of the lens body ranges from about 0.14 to about 0.25.

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.
