London Restaurant VIVI Illuminates the Building’s History With Retro Lighting

One of the newest additions inside London’s iconic Centre Point tower is VIVI, a brasserie and bar from hospitality group rhubarb. Located on the main floor, the restaurant overlooks New Oxford Street and the surrounding square. The vibrant interior design takes much inspiration from the 1960s, the decade in which the tower was built. Gordon Young Architects, the restaurant’s interior design firm, entrusted the lighting configuration to London-based Nulty Lighting, who incorporated such luminaires as a bespoke chandelier suspended over the dining area, clustered ceiling downlights and diffused lights integrated under the bar countertop.

‘Reverse trick’ for LEDs could keep future computers cool

In a finding that runs counter to a common assumption in physics, researchers ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away.

The approach could lead to new solid-state cooling technology for future microprocessors, which will have so many transistors packed into a small space that current methods can’t remove heat quickly enough. “We have demonstrated a second method for using photons to cool devices,” says Pramod Reddy, who co-led the work with Edgar Meyhofer, both professors of mechanical engineering at the University of Michigan.

Firefly-inspired surfaces improve efficiency of LED lightbulbs

A new type of light-emitting diode lightbulb could one day light homes and reduce power bills, according to Penn State researchers who suggest that LEDs made with firefly-mimicking structures could improve efficiency.

 "LED lightbulbs play a key role in clean energy," said Stuart (Shizhuo) Yin, professor of electrical engineering. "Overall commercial LED efficiency is currently only about 50 percent. One of the major concerns is how to improve the so-called light extraction efficiency of the LEDs. Our research focuses on how to get light out of the LED."

Fireflies and LEDs face similar challenges in releasing the light that they produce because the light can reflect backwards and is lost. One solution for LEDs is to texture the surface with microstructures — microscopic projections — that allow more light to escape. In most LEDs these projections are symmetrical, with identical slopes on each side.

Understanding how people experience LED-light fluctuation

Light emitted by LEDs can flicker or exhibit a stroboscopic effect, which can lead to annoyance, fatigue and even headaches. Researchers at Eindhoven University of Technology and Signify determined the characteristics of light at which the human eye no longer perceives these unwanted effects. The model developed allows lighting manufacturers to test for these undesirable effects while designing their LED products. Researchers searched for the exact value of specific light characteristics at which the stroboscopic effect becomes invisible to the human eye; the visibility threshold. She invited more than 200 persons, in a simulated office environment, to look at a black disk with a white dot under a LED light source.

Prescription Lighting Is Closer to Reality Than You May Think

Although the international lighting community does not yet know enough to prescribe a certain type of electric lighting to meet the specific needs of specific individuals, enough has been learned in the past few years “to make a difference in people’s lives,” according to Mariana G. Figueiro, Ph.D., director of the Lighting Research Center, a professor of architecture at Rensselaer Polytechnic Institute, and a member of the “Prescription Lighting” discussion panel convened at the National Lighting Bureau’s 7th Annual Lighting Forum. Robert Soler, vice president of human biological technologies and research with BIOS Lighting, was the other panelist. EdisonReport Editor and Publisher and Illuminating Engineering Society (IES) Past President Randy Reid moderated the discussion.

Perovskite, The New LED

Perovskite LEDs (or PeLEDs) have attracted interest from the research community, as they have demonstrated that their colors can be stronger and more adjustable compared to current models. This is due to the potential improvements in terms of the properties of charge-transfer and external quantum efficiency (EQE) PeLEDs could bring. On the other hand, these attributes have been associated with hybrid varieties of these compounds. They have both organic and inorganic chemical make-ups. This dual nature creates problems for LED developers.

New UVC LED Performance Benchmark Promises to Revolutionize Disinfection

Global public health concerns have heightened following reports of disease outbreaks from food or water contamination in restaurants, retail and hospitality businesses. Alarms are also raised from recent incidences of “superbug” infections and persistently high hospital-acquired infection rates. As pathogens acquire drug resistance and becoming more virulent, the public needs a proven prevention technique to ensure safe food, clean water, and sanitized air in homes and shared spaces in urban areas. Ultraviolet C-band light-emitting diode (UVC LED) is now increasingly recognized as a technology-of-choice that offers effective, universal and chemical-free protection.

Germicidal UVC LED supplier Bolb Inc., based in Livermore, California, has announced further advancements of its high performance UVC LEDs featuring record 250mW single-chip performance during a technical presentation given today at the SPIE Photonics West Conference held this week in San Francisco, CA.

Bolb is the first—and so far the only—LED company in the world to overcome one of the most difficult engineering challenges in making UVC LEDs: producing a crystal structure fully transparent to UVC light for maximum output efficiency. The company’s latest high-power UVC LEDs have delivered industry-leading efficiency, offering 250 mW of single-chip optical output at the optimized disinfection wavelengths of 265-270 nm. This unprecedented single chip output power is achieved at 500mA drive current with a forward voltage of 5.8V. Even higher power can be achieved with multi-chip arrays.

Hardware Resources has 700 employees and eight distribution centers across the nation. After the acquisition, Task Lighting and Hardware Resources spent eight months integrating computer systems and resources here to unify the two businesses. That work was completed Sept. 1. “We got the kinks worked out. We can focus on growing the product line and making it as efficient as we can,” Bartek said.

Why Greenhouse Growers Have Been Slow to Shift to LEDs

Almost all of the most recent research into greenhouse lighting has focused on light-emitting diode (LED) technology. There’s a good reason for this, as the long-term energy savings that can come from the use of LEDs — and the rebates and local grant programs that growers can take advantage of — make it an appealing option. So why are only around 2% of greenhouse ornamental growers (according to Erico Mattos, Executive Director of the GLASE consortium) using LED systems? If you talk to industry suppliers, there is a host of reasons. “Lighting, on average, is 50% of a commercial operation’s energy costs, but the economic feasibility of switching to LEDs is not always the most important thing on growers’ minds,” says Taylor Schaberg, Managing Director of ActiveGrow.

What Happened to the 100,000-Hour LED Bulbs?

Early adopters of LED lighting will remember 50,000 hour or even 100,000 hour lifetime ratings printed on the box. But during a recent trip to the hardware store the longest advertised lifetime I found was 25,000 hours. Others claimed only 7,500 or 15,000 hours. And yes, these are brand-name bulbs from Cree and GE. So, what happened to those 100,000 hour residential LED bulbs? Were the initial estimates just over-optimistic? Was it all marketing hype? Or, did we not know enough about LED aging to predict the true useful life of a bulb?

DOE Lighting Rollback Proposal Will Cost Consumers Billions

The U.S. Department of Energy’s proposal to dramatically narrow the scope of light bulbs covered by the upcoming federal 2020 energy efficiency standards will cost consumers up to $12 billion on their utility bills and cause up to 25 more coal burning power plants worth of electricity to be generated every year.
