Accessories for LED lamps
View Patent ↗Accessories for LED lamps and methods of attaching accessories to illumination sources (e.g., LED lamps) are disclosed. A beam shaping accessories mechanically affixed to the LED lamp. The lens is designed to adapt to a first fixture that is mechanically attached to the lens. Accessories are designed to have a second fixture for mating to the first fixture such that the first fixture and the second fixture are configured to produce a retaining force between the first accessory and the lens. In some embodiments, the retaining force is a mechanical force that is accomplished by mechanical mating of mechanical fixtures. In other embodiments, the retaining force is a magnetic force and is accomplished by magnetic fixtures configured to have attracting magnetic forces. In some embodiments, the accessory is treated to modulate an emanated light pattern (e.g., a rectangular, or square, or oval, or circular or diffused emanated light pattern).
1. An apparatus comprising:
an LED lamp, wherein the LED lamp radiates an initial light pattern;
a lens comprising a center, wherein the lens is mechanically affixed to the LED lamp;
a first magnet, wherein the first magnet,
is attached to and centered on the lens; and
is configured to block at least a portion of high-angle light radiating from the LED lamp; and
a first accessory comprising a second magnet, wherein,
the first accessory is mated in proximity to the lens using the first magnet and the second magnet; and
the second magnet is attached to and centered on the first accessory;
wherein the first magnet and the second magnet are configured to produce a retaining force between the first accessory and the lens; and
wherein the first accessory is configured to control the initial light pattern to provide a radiated light pattern.
2. The LED lamp of claim 1 , wherein the second magnet and the first accessory have a combined thickness less than 2 mm.
3. The LED lamp of claim 1 , wherein the first magnet and/or the second magnet comprises a disk magnet.
4. The LED lamp of claim 3 , wherein the disk magnet comprises at least one surface that is treated to control an emanated light pattern.
5. The LED lamp of claim 1 , wherein the first magnet and/or the second magnet comprises a doughnut magnet.
6. The LED lamp of claim 5 , wherein the doughnut magnet comprises at least one surface that is treated to control an emanated light pattern.
7. The LED lamp of claim 1 , wherein the first accessory comprises a thin plastic film.
8. The LED lamp of claim 7 , wherein the thin plastic film has a thickness less than 3 mm.
9. The LED lamp of claim 1 , wherein the first accessory has a diameter that is substantially the same as a diameter of the lens.
10. The LED lamp of claim 1 , wherein the first accessory is selected from a lens, a diffuser, a color filter, a polarizer, a linear dispersion element, a collimator, a projector accessory, and a combination of any of the foregoing.
11. The LED lamp of claim 1 , further comprising an accessory selected from a louver, a baffle, a secondary lens, and a combination of any of the foregoing.
12. The LED lamp of claim 1 , wherein the lens comprises a total internal reflection lens.
13. The LED lamp of claim 1 , wherein the LED lamp is characterized by an optical aperture and the lens is configured to cover more than 90% of the optical aperture.
14. The LED lamp of claim 1 , further comprising a second accessory disposed adjacent the first accessory, wherein,
the second accessory comprises a third magnet;
the second accessory is mated to the first accessory using the second magnet and the third magnet; and
the second magnet and the third magnet are configured to produce a magnetic retaining force between the second accessory and the first accessory.
15. The LED lamp of claim 1 , wherein at least one surface of the first magnet is treated to control an emanated light pattern.
16. The LED lamp of claim 1 , wherein the first accessory comprises an oval pattern beam shaping accessory.
17. The LED lamp of claim 1 , wherein the first accessory comprises a square pattern beam shaping accessory.
18. The LED lamp of claim 1 , wherein the first accessory comprises a rectangular pattern beam shaping accessory.
19. The LED lamp of claim 1 , wherein the first accessory comprises a honeycomb louver accessory.
20. The LED lamp of claim 1 , wherein the first accessory comprises a half dome diffuser accessory.
21. The LED lamp of claim 1 , wherein the first magnet is attached to the lens with an ultra-sonic weld.
22. The apparatus of claim 1 , wherein the radiated light pattern has reduced glare compared to the initial light pattern.
23. The apparatus of claim 1 , wherein the first magnet comprises a reflective coating configured to reflect high angle light toward the LED light source.
24. The apparatus of claim 1 , wherein the first magnet comprises a coating configured to absorb light.
25. The apparatus of claim 1 , wherein the first magnet and the second magnet are configured to attenuate glare.
26. The apparatus of claim 1 , wherein the lens comprises a pocket and the first magnet is disposed within the pocket.
