Light emitting apparatus
DCFirst Claim
1. A light emitting apparatus comprising:
- 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 downwardly concave first recess formed at a center of a top surface of the lens body and an upwardly concave second recess formed at a center of a bottom surface of the lens body, and at least one of lens supporters 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, andwherein a thickness of the lens body between a bottom surface of the downwardly concave first recess and a top surface of the upwardly concave second recess increases from a center region of one of the downwardly concave first recess or the upwardly concave second recess to an end region thereof,wherein a ratio of a maximum depth of the first recess to a maximum depth of the second recess is about 6.25 to 10.

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.

12. A light emitting apparatus comprising:
-
a substrate; a light emitting device on the substrate; a fluorescent layer on the light emitting device to surround the light emitting device; an encapsulant resin layer on the fluorescent layer to surround the fluorescent layer; and a lens on the light emitting device and supported by the substrate, wherein the lens includes a lens body having a first recess and a second recess and at least one lens supporter, the first recess formed at a center of a top surface of the lens body and that extends toward a central portion of the lens body, and the second recess formed at a center of a bottom surface of the lens body and that extends toward the central portion of the lens body, and wherein the first recess vertically overlaps the second recess, and the at least one lens supporter is provided at the bottom surface of the lens body to support the lens body such that the lens body is spaced from the substrate, and wherein a thickness of the lens body between a bottom surface of the first recess and a top surface of the second recess increases from a center region of one of the first recess or the second recess to an end region thereof, wherein a ratio of a maximum depth of the first recess to a maximum depth of the second recess is about 6.25 to 10. - View Dependent Claims (13, 14, 15, 16, 17, 18)
