Abstract

An optical assembly for use with one or more LED packages for capturing and redirecting light. The optical assembly can include an optical component and an alignment structure connected to the optical component for aligning the optical component to the LED package.

Claims

1. An optical assembly for use in conjunction with an LED package comprising:

an optical component for redirecting light from said LED package; and

an alignment structure connected to said optical component configured to align said optical component with respect to said LED package such that said optical component maintains a substantially fixed position with respect to said LED package.

2. The optical assembly of claim 1, wherein the optical assembly is an integral piece of optical material.

3. The optical assembly of claim 1, wherein the alignment structure comprises at least one elongate member.

4. The optical assembly of claim 3, wherein the at least one elongate member is configured to attach to the LED package.

5. The optical assembly of claim 1, wherein the package comprises a lens, and wherein the optical component substantially covers the LED package.

12. The optical assembly of claim 11, further comprising a protrusion configured to connect the connector portion to a circuit board.

13. The optical assembly of claim 12, wherein the optical assembly is an integral piece of optical material.

14. The optical assembly of claim 12, wherein the protrusion comprises a plurality of clips for snapping the optical assembly onto the circuit board.

6. An optical assembly for use in conjunction with a plurality of LED packages comprising:

a plurality of connected optical components associated with each of the plurality of packages,

at least one alignment structure connected to the plurality of optical components for aligning the components with their associated LED packages.

7. The optical assembly of claim 6, wherein the optical assembly is an integral piece of optical material.

8. The optical assembly of claim 6, wherein the alignment structure comprises at least one elongate member.

9. The optical assembly of claim 8, wherein the at least one elongate member is configured to attach to at least one of the LED packages.

10. The optical assembly of claim 6, wherein the one optical component substantially covers at least one of the LED packages.

11. The optical assembly of claim 6, further comprising a connector portion for connecting the optical components.

15. A modified LED package comprising:

an LED package comprising;

an LED body,

a set of leads, and

an integral lens; and

an optical assembly secured to the LED package comprising;

an optical component for redirecting light from the LED package, and

an alignment structure connected to the optical component configured to align the optical component with respect to the LED package.

16. The optical assembly of claim 15, wherein the alignment structure comprises at least one elongate member.

17. The optical assembly of claim 16, wherein the at least one elongate member is configured to attach to the LED package.
