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