LED art is a form of
light art
Light art or The Art of Light is generally referring to a visual art form in which (physical) light is the main, if not sole medium of creation. Uses of the term differ drastically in incongruence; definitions, if existing, vary in several asp ...

guerrilla artists, incorporating LEDs to produce temporary pieces in public places. LEDs may be used in installation art, sculptural pieces and interactive artworks.

s, New Year's Eve parties and nighttime sporting events.
There is no industry standard or official name for blinkies, but most common names use some combination of the terms flash, magnet, strobe, body, blink, light, and/or jewelry. Common examples are blinkies, blinkees, body lights, blinky body lights, magnetic flashers, or flashing jewelry.
Uses
Blinkies are most often used for amusement at raves, parties and nighttime events. Their other uses include:
* Blinkies imprinted with company logos at conventions
* Safety lights for children during Halloween, or nighttime events
* Fun and safety during camping trips
* Emergency flashers for disabled automobiles or lost hikers (most blinkies have over a one-mile visibility range at night)
* The term blinky is often used for bicycle lights which flash. In some countries, blinkies can be used as a primary light on a bicycle.
* Blinkies also can be attached to mobiles (cell phones). When the mobile turns on, makes a call, or receives a call, the blinky will keep flashing.
* "Winky blinkies" can refer to stage and film props which display lighting effects, or "gags," during a dramatic production.
Construction
Body
A typical blinky is a small plastic two-piece cylinder wide enough to accept a button cell battery with a small etched circuit board on the face and threads on the open end, paired with a cylinder cap which screws on to seal and secure as one. The flashing LED circuit board face can be round and enclosed by the cylinder, or a variety larger colored shapes such as logos that are glued to the outside face of the cylinder end. Common designs utilize a rubber ring gasket as an on/off switch. When placed between the batteries and circuit board inside the front cover, tightening the screw base deforms and flattens the gasket forcing the battery tip to contact the back of the printed circuit board, which completes the circuit. Modern blinkees are more likely to use a battery case that opens with a small eyeglasses type screw and a push button on/off switch.
Back
The most common designs use a set of strong magnets, one at the back of the blinky, and another that can be removed. This allows the light to be easily attached to clothes, or stuck onto any magnetic metal such as buttons or belt buckles. Clips are often used to make earrings, a loop can make a pendant, or a ring can be welded to the back to make a finger ring. Double sided adhesive pads are sometimes used to stick the blinky directly to the body, most often in the navel.
Circuit board
The circuit board typically has anywhere from 2 to as many as 25 micro-LEDs. LEDs that emit different

within the visible spectrum are commonly used, whereas ultraviolet or infrared LEDs are less common in blinkies. Blue, white, violet, and ultra-violet LEDs often require two or more battery cells, due to their higher voltage requirements. The visible side of the etched circuit board can be constructed to flash in a variety of ways, especially where there are multiple LEDs in multiple colours. A clear plastic
