Art LED is a light art form built from a light-emitting diode. LED (light emitting diode) is very cheap to buy and has become a new way to create street art. Many artists who use LEDs are guerrilla artists, combining LEDs to produce temporary cuts in public places. LEDs can be used in installation art, sculptural pieces and interactive artwork.

Famous LED Art
In early 2007, there was a fear of bombs in Boston, Massachusetts in the United States caused by a guerrilla marketing campaign. An advertising company working for Turner Broadcasting System Inc. to promote the network animation television show Aqua Teen Hunger Force , hired two artists to produce art for an advertising campaign. The artists put the LED signs in various locations in ten cities. However, Boston is the only city that reacts by closing the bridge and bringing the bomb squad to remove the LEDs. The majority of light boards are removed and the artists are captured.

Artist and function combine LED
- Jenny Holzer - One of the most famous artists who incorporate LEDs into his work. He uses familiar statements and interprets them to change their meaning.
- Meeli KÃÆ'Âμiva (aka Mery Crystal Ra) - an artist who gained recognition for his installation of "Reactive River" (main building of the European Parliament, Brussels, Belgium)
- Cell Phone Disco by Informationlab (Ursula Lavren? i? and Auke Touwslager) is an installation that uses the electromagnetic spectrum emitted by the viewer's phone and creates a visual interpretation. LED is attached to a large network and when the phone is switched on in the room, the light will light up.
- GreenPix - Zero Energy Media Wall - created as an environmentally friendly art space. Serves as a low resolution screen for artists to show their work.
- Liz LaManche - creates large paintings illuminated by color-changing LED lights for motion effects
- TheStrober - Uses strobe art in youtube videos to give the illusion of moving wheels or changing faces, usually set to dance or thrash metal music.
- Liu Dao - an art group in China that uses actors and filmmakers to create animated LED images. The group also combines traditional Chinese art such as cutting paper with LEDs to highlight China's journey from tradition and modernity, and is directed by Thomas Charvà ©  © riat to discover originality through international collaboration.
- Titia Ex - artist from Amsterdam known for his installation Flower of the Universe
- Leo Villareal - combines LED lights and computer programming encoded to create an illuminated display
- Jim Campbell - LED Artist living in San Francisco
LED throws
LED bullets are small LEDs attached to rare coin and earth magnetic batteries (usually with conductive epoxy or electrical tape), used for the purpose of creating non-destructive graffiti and light displays. Artists throw LEDs to metal objects, such as public sculptures or road infrastructure, that serve as canvas. Led throwies were discovered in 2006 by artists Evan Roth and James Powderly, founder of the Graffiti Research Lab at Eyebeam Atelier opened the New York City lab. After the Graffiti Research Lab posts instructions on how to make a throw in Instructables, a virus throw on the Internet and can be found in ads, sold as a DIY kit or further developed by hackers and other hackers around the world.
Blinkies
Blinkies are small electronic devices that make very bright light (usually blinking) using LED lights and small batteries. They are often sold by vendors on night shows featuring fireworks such as Independence Day, Canada Day, or Guy Fawkes Night. They are also popular in raves, New Year's Eve parties and evening sports.
There are no industry standards or official names for blinkies, but the most common names use some combination of flash, magnetic, strobe, body, blink, light, and/or jewelry terms. Common examples are blinkies, blinkees, body lights, blinky body lights, magnetic flashers, or flashing jewelry.
Usage
Blinkies are most often used for entertainment in raves, parties and nighttime events. Other uses include:
- Blinkies are printed with the company logo at the convention
- Safety lights for children during Halloween, or evening shows
- Fun and security during camping trips
- Emergency flashers for disabled cars or lost pedestrians (most blinkies have a range of one mile at night)
- The term blinky is often used for lighted bicycle lights. In some countries, blinkies can be used as a headlight on a bicycle.
- Blinkies can also be attached to a mobile phone (phone). When the phone is on, making a call, or receiving a call, blinky will continue to burn.
- "Winky blinkies" can refer to stage props and movies that feature lighting effects, or "jokes", during dramatic production.
Construction
Body
A typical blinky is a small metal two-piece cylinder wide enough to receive a button cell battery with a small scratched circuit board on the face and yarn on the open end, paired with a screw cylinder cap to seal and secure as one. The face of a flashing LED circuit board can be round and enclosed by a cylinder, or any larger color shapes such as a logo attached to the outer surface of the cylinder end. The general design utilizes a rubber ring gasket as an on/off button. When placed between the battery and the circuit board inside the front cover, tighten the deforms screw base and flatten the gasket which forces the battery end to contact the back of the printed circuit board, which completes the circuit.
Back
The most common design uses a powerful set of magnets, one behind the blinky, and the other that can be removed. This allows light to easily cling to clothing, or stick to magnetic metals such as buttons or belts. Clips are often used to make earrings, a circle can make a pendant, or a ring can be welded backwards to make a finger ring. Double-sided adhesive pads are sometimes used to attach blinky directly to the body, most often at the navel.
Circuit board
Circuit boards usually have between 2 to 25 micro-LEDs. LEDs that emit different colors in the visible spectrum are typically used, whereas ultraviolet or infrared LEDs are less common in blinkies. Blue, white, purple, and ultra-violet LEDs often require two or more battery cells, due to higher voltage requirements. The visible side of the engraved circuit board can be built to flash in various ways, especially where there are many LEDs in different colors. Clear plastic conformal coating materials such as silicone, acrylic or epoxy protect the fragile LEDs on the front of the open board. Shaped boards have hundreds of variations combined with printing. Common forms (besides the classic little circle) are stars, hearts, flowers, flags, animals, holiday symbols (like Halloween jack-o-lanterns), and sports team logos.
