## Abstract

Accessories for LED lamp systems 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. The retaining force is a mechanical force that is accomplished by mechanical mating of mechanical fixtures, or 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). A USB connector is also provided.

## Claims

### Claim 1

An apparatus comprising:
an LED lamp, the lamp emanating an initial light pattern;
a lens, the lens mechanically affixed to the LED lamp;
a first fixture mechanically attached to the lens;
a first accessory comprising a second fixture, wherein the first accessory is mated in proximity to the lens using the first fixture and the second fixture; and
wherein the first accessory is configured to modulate the initial emanated light pattern.
