Abstract

A lens and a light emitting device package formed by introducing surface mount technology (SMI) are disclosed. The lens includes a refractive portion which refracts incident light, and at least one surface mount portion, wherein a portion of the surface mount portion is formed in the refractive portion.

Claims

1. A light emitting device package comprising:

a substrate;

a light emitting portion disposed on the substrate;

a lens covering over the light emitting portion so as to refract a direction of light emitted from the light emitting portion.

2. The light emitting device package according to claim 1, wherein an upper surface of the light emitting portion is substantially planar.

3. The light emitting device package according to claim 1, wherein an upper surface of the light emitting portion is contacted with the lens.

4. The light emitting device package according to claim 1, wherein an entire lateral surface of the light emitting portion is contacted with the lens.

5. The light emitting device package according to claim 1, wherein the light emitting portion is located at a central portion of the lens.

6. The light emitting device package according to claim 1, wherein the lens has an empty space with a prescribed depth at a central portion of a lower surface of the lens.

7. The light emitting device package according to claim 6, wherein an entire upper surface and a part of a lateral surface of the emitting portion are located in the empty space of the lens.

8. The light emitting device package according to claim 1, wherein an entire upper surface and a part of a lateral surface of the emitting portion are surrounded by the lens.

9. The light emitting device package according to claim 1, wherein an upper surface of the lens is substantially a curved surface.

10. The light emitting device package according to claim 1, wherein a thickness of the lens is decreased from an inward portion corresponding to the light emitting portion to an outward portion.

11. The light emitting device package according to claim 1, wherein a thickness or a height of the lens is different from that of the substrate.

12. The light emitting device package according to claim 1, wherein an entire thickness or a height of the lens is greater than that of the substrate.

13. The light emitting device package according to claim 1, wherein a thickness of the lens is different from that of the light emitting portion.

14. The light emitting device package according to claim 1, wherein a thickness of the lens is greater than that of the substrate.

15. A light emitting device package comprising:

a substrate;

a light emitting portion disposed on the substrate;

a lens covering over an upper surface and a part of a lateral surface of the light emitting portion.
