LED art is a form of light art constructed from light-emitting diodes. LEDs (light emitting diodes) are very inexpensive to purchase and have become a new way to make street art. Many artists who use LEDs are guerrilla artists, incorporating LEDs to produce temporary pieces in public places. LEDs may be used in installation art, sculptural pieces and interactive artworks.
Infamous LED art
In early 2007, there was a bomb scare in Boston, Massachusetts in the United States caused by a guerrilla marketing campaign. An advertising firm working for Cartoon Network to promote the network's animated television show Aqua Teen Hunger Force, hired two artists to produce art for the ad campaign. The artists placed LED signs in various locations across ten cities. However, Boston was the only city that reacted by shutting down bridges and bringing in bomb squads to remove the LEDs. The majority of the light boards were removed and the artists were arrested. Cartoon Network general manager Jim Samples resigned as a result of the incident.
Artists and works incorporating LEDs
The neutrality of this section is disputed. (January 2014) (Learn how and when to remove this template message)
- Jenny Holzer - One of the most well known artists who incorporates LEDs into her work. She uses familiar statements and reinterprets them to alter their meanings.
- Meeli Kõiva (aka Mery Crystal Ra) - an artist who achieved acknowledgement for her installation "Reactive River" (European Parliament main building, Brussels, Belgium)
- Cell Phone Disco by Informationlab (Ursula Lavrenčič and Auke Touwslager) is an installation that uses the electromagnetic spectrum emitted by the viewer’s cell phone and creates a visual interpretation. The LEDs are attached to large grids and when a phone is activated in a section of the room, the lights turn on.
- GreenPix – Zero Energy Media Wall – created as an environmentally friendly art space. It acts as a low resolution screen for artists to show their work.
- Liz LaManche - creates large paintings illuminated by color-changing LED light for a motion effect
- TheStrober - Uses strobe art in youtube videos to give the illusion of wheels moving or faces changing, usually set to dance or thrash metal music.
- Liu Dao - an art collective in China that uses actors and filmmakers to make animated LED portraits. The group also combines traditional Chinese arts like papercutting with LEDs to highlight China's journey from tradition and modernity, and is directed by Thomas Charvériat to find originality through international collaboration.
- Titia Ex - artist from Amsterdam who is known for her installation Flower of the Universe
- Leo Villareal - combines LED lights and encoded computer programming to create illuminated displays
- Jim Campbell - LED artist based in San Francisco
- Teddy Lo - LED artist based in Hong Kong
An LED throwie is a small LED attached to a coin battery and a rare earth magnet (usually with conductive epoxy or electrical tape), used for the purpose of creating non-destructive graffiti and light displays. Artists throw individual LEDs onto a metallic object, like public sculpture or road infrastructure, which itself acts as a canvas. LED throwies were invented in 2006 by the artists Evan Roth and James Powderly, the founder of Graffiti Research Lab at Eyebeam Atelier open lab New York City. After Graffiti Research Lab posted the instructions how to make a throwie on Instructables, throwies went viral on the Internet and could be found in advertising, were for sale as DIY kits or further developed by other artists and hackers worldwide.
Blinkies are small electronic devices that make very bright (usually flashing) light using LEDs and small batteries. They are often sold by vendors at night-time events that have fireworks displays such as Independence Day, Canada Day, or Guy Fawkes Night. They are also popular at raves, 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.
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.
A typical blinky is a small metal 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.
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.
The circuit board typically has anywhere from 2 to as many as 25 micro-LEDs. LEDs that emit different colors 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 conformal coating material such as silicone, acrylic or epoxy protects the fragile LEDs on the exposed front of the board. Shaped boards have literally hundreds of variations combined with imprinting. Common shapes (besides the classic small circle) are stars, hearts, flowers, flags, animals, holiday symbols (like Halloween jack-o-lanterns), and sports team logos.
