Abstract

Apparatus and methods of attaching accessories to LED lamps and for providing active accessories in LED lamps are disclosed.

Claims (26)

1. A light emitting diode (LED) lamp comprising:

a lens having a center and a diameter;

a first magnet attached to the center of the lens;

a first accessory having a center, wherein the first accessory is disposed on the lens; and

a second magnet attached to the center of the first accessory;

wherein the first magnet and the second magnet are configured to retain the first accessory against the lens.

2. The LED lamp of claim 1 , wherein the first accessory comprises a thin plastic film.

3. The LED lamp of claim 1 , wherein the first magnet and the second magnet are configured to retain the first accessory against a perimeter of the lens.

4. The LED lamp of claim 1 , wherein the first accessory has a diameter that is substantially the same as the diameter of the lens.

5. The LED lamp of claim 1 , wherein the first accessory has a diameter that is the same as the diameter of the lens.

6. The LED lamp of claim 1 , wherein the first accessory has a diameter that substantially covers an optical region of the lens.

7. The LED lamp of claim 1 , wherein the lens is configured to attach to an MR16 lamp.

8. The LED lamp of claim 1 , wherein the first accessory is selected from a diffuser, a color filter, a polarizer, a linear dispersion element, a baffle, and a combination of any of the foregoing.

9. The LED lamp of claim 1 , wherein the first magnet and the first accessory have a combined thickness less than 1 mm.

10. The LED lamp of claim 1 , wherein the lens comprises a folded total internal reflection lens.

11. The LED lamp of claim 1 , wherein the lamp is characterized by a lamp output mechanical aperture; and the lens is configured to cover more than 90% of the lamp output mechanical aperture.

12. The LED lamp of claim 1 , comprising a second accessory having a center, wherein the second accessory is disposed adjacent the first accessory.

13. The LED lamp of claim 12 , wherein second accessory comprises a third magnet, wherein the third magnet is attached to the center of the second accessory.

14. An apparatus for providing active accessories in a light emitting diode (LED) lamp, comprising:

an LED illumination product having a lens and a housing;

at least one electronic component disposed within the housing; and

at least two electrical conductors electrically-connected to the at least one electrical component, the at least two electrical conductors disposed within a rigid member affixed to the lens.

15. The apparatus of claim 14 , wherein the rigid member accepts a USB connector.

16. The apparatus of claim 14 , wherein the rigid member is made of a magnetic material.

17. The apparatus of claim 14 , wherein the rigid member is affixed to the lens with an adhesive.

18. The apparatus of claim 14 , wherein the rigid member is affixed to the lens with a mechanical connector.
