Amazing Light and Shadow Art by Kumi Yamashita

Living and working in New York City, Japanese artist Kumi Yamashita has a series of work using simple shapes and objects with light to create the most incredible shadows. Using a single light source that projects light onto the material, Yamashita forms silhouettes of people and faces in the series entitled Light & Shadow.

Images from the Edinburgh Festival 2012’s installation Speed of Light

This August Edinburgh’s Arthur’s Seat is the stage for a remarkable fusion of public art and sporting endeavour. The iconic mountain is brought to life in a mass choreographed act of walking and endurance running, as part of Edinburgh International Festival and London 2012 Festival.
A mesmerising visual display unfolds each night on the ascent to the summit as hundreds of runners wearing specially designed light suits take to the intricate path networks below. As a member of the walking audience you become part of the work, carrying portable light sources set against the dark features of the hill.

Topographic Light Painting Maps Rooms and People in 3-D

For years Janne Parviainen worked as a painter, happy with two-dimensions, until he came across light painting photography. He realized the technique could bring out that third, illusive dimension of depth in a way paint and canvas could not.
“It was a whole new challenge,” says Parviainen, 32, who lives in Helsinki, Finland.
His topographic light paintings circumscribe surfaces and people throughout his house, creating captivating 3-D models in the process. Parviainen first started in 2007 by using small LED lights to trace human bodies, using his wife and himself for models. He quickly grew more ambitious, creating multi-person shots where he would trace himself multiple times, creating the appearance of an entire audience.

Odaiba Water Illumination Show in Japan is a Stunning Spectacle of Marine Life.

Against a backdrop of the Rainbow Bridge and the city’s skyline, the Odaiba water illumination show in Japan is a stunning spectacle of marine life.
Fountains set along a beach at the Tokyo Bay area create a screen of water to project pictures of an ocean adventure. The show is performed four times after sunset in the Japanese capital.

Odaiba is an artificial island that was originally there to defend Tokyo from attacks.

Among the many images screened are frolicking dolphins, tropical fish, a whale and narwhals against a colourful array of lights.

Lighting Research Center: Light from Self-Luminous Tablet Computers Can Affect Evening Melatonin, Delaying Sleep

A new study from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute shows that a two-hour exposure to electronic devices with self-luminous “backlit” displays causes melatonin suppression, which might lead to delayed bedtimes, especially in teens.

The research team, led by Mariana Figueiro, associate professor at Rensselaer and director of the LRC’s Light and Health Program, tested the effects of self-luminous tablets on melatonin suppression. In order to simulate typical usage of these devices, 13 individuals used self-luminous tablets to read, play games, and watch movies. Results of the study, titled “Light level and duration of exposure determine the impact of self-luminous tablets on melatonin suppression,” were recently published in the journal Applied Ergonomics.

AWA Project Fairmont Jaipur Hotel is Now Open

The Fairmont Jaipur officially opened on August 9th, 2012 and is Fairmont’s first hotel in India. The luxury hotel and resort operating company has created magnificent hotels all around the world, and the Jaipur is no exception. Exquisitely designed by Randolph Gray, It reflects and complements the uniqueness of the community in which it is situated by following the spectacular architectural style that is seen in the surrounding palaces. In addition to the 248 rooms, guests are offered a variety of restaurants and bars, including a poolside bar, a 10,000 square foot Willow Stream spa, and a 5,000 square foot health club. The hotel’s magnificent 48,500 square foot Convention Center and gardens can host over 1000 guests within its richly adorned spaces.

Our lighting concept for the Fairmont Jaipur creates dramatically illuminated spaces, fully capitalizing on the romance inherent in the architectural styling. Unexpected moments of delight are created by special accents, such as candle-light effects on entry stairs, pool-side torches, and lighting effects that erupt into richly textured patterns of shadows on plain walls. The guest’s gait is the primary focus of the landscape lighting, which draws visitors along and peaks their curiosity by pacing illumination low along paths. Visitor’s attention is drawn towards dining areas and other outdoor focal points through the use of delicately illuminated trees with hanging fixtures. Large spaces with high ceilings are filled with the warm glow of low-hanging chandeliers, creating an intimate place from a very open space.

Add LED Intelligence–Improve light quality, efficiency and cost

As the lighting industry continues to make the transition to LED technology, there is an increasing need for more intelligent controllers and drivers. The rising price of electricity presents a major operating cost to consumers and businesses; however, efficient operation of LEDs can result in substantial savings. Many applications need to produce consistent light quality while supporting advanced control functionality such as dimming, balancing, and accurate color mixing. Remote connectivity is also becoming a regular requirement in applications where high-maintenance expenses can be reduced through self-diagnostics that allow technicians to make a service call only when there is an actual reason to visit a site.

AWA to Light Hazratbal Shrine

Considered to be Kashmir’s holiest Muslim shrine, Hazratbal Shrine contains a relic believed by Muslims to be a hair of the Prophet Muhammad. It is situated on Dal Lake in the municipality of Srinagar. It was originally built by Sadiq Khan, the Subedar of Mughal Emperor Shahjahan as a Palace with a garden in 1623, but was later converted into a prayer house in 1634 as ordered by Emperor Shahjahan.

AWA’s intent with this project is to provide a lighting solution that highlights the natural beauty of the shrine’s architecture, as well as the connection between the visual and the physical approach to the building. The lighting design approach provides a sense of calm and clarity that augments the spiritual purity of the site.

The large dome of the shrine will be illuminated as the primary focal point of the design, and its massing will be highlighted so as to create a monument to the city of Srinagar. The arched openings located along each façade will be grazed with light, and the texture of the screens between the openings will be lit from within, making the building appear to be glowing from within, while highlighting the texture of the ornate screens.

This project is undertaken by AWA as part of our community work where we contribute our time and undertake lighting projects for the public good on a pro-bono basis.

A light-emitting diode using deoxyribonucleic acid

Replacing epoxy with DNA in white LEDs can enhance light output and efficiency, as well as redshifting the emission to render warmer lighting with longer lifetimes.

Like fluorescent lighting, solid state lighting uses phosphors to realize the desired color output. Commercial white solid state lighting typically uses gallium nitride (GaN) semiconductor-based blue LEDs operating at wavelengths of 450–470nm. That blue light excites a yellow-emitting phosphor powder, such as cerium-doped yttrium aluminum garnet (YAG:Ce), which is blended or encapsulated with epoxy on top of the LED die (see Figure 1).1–7 This process results in some of the blue LED light being converted to a wavelength of about 560nm. The yellow light stimulates the red and green receptors of the eyes, and the resulting mix of blue and yellow gives the appearance of white light. This white light, however, typically has a blue tint, which is referred to as cold light. Increasing the phosphor-emitted light’s wavelength so that it is closer to red can reduce or eliminate the blue tint, producing a warm light. However, while the YAG:Ce is very efficient in blue-to-yellow light conversion, the newer red phosphor blends reduce the light output’s brightness and efficiency.8, 9 In addition, and more important, the light output of and heat produced by the GaN LED die has been shown to degrade the epoxy/phosphor material, thus reducing the device’s lifetime.
