How Flagstaff, Arizona, switched to LEDs without giving astronomers a headache

A few years ago a problem arose in Flagstaff, Arizona. The type of dark-sky-friendly streetlight that the city had been using was going extinct, largely as a casualty of low demand. In fact, as of this summer, there are none left to buy. Meanwhile, the age of the LED streetlight has arrived with a catch: limited night-sky-friendly LED options. If the city went out and just swapped lumens for the cheapest LED products out there, the astronomers would have marched on city hall with pitchforks and (night-vision-preserving) torches. And that might have been the least of their concerns, as the Navy informed the city last year that “brightening of skies 10 percent over current conditions is not compatible with the [Naval Observatory’s] mission.”

Beauty and the beam: the future of LED therapy looks bright

In the beauty world, the popularity of LED therapy is growing exponentially. In part, this is due simply to its increasing availability. According to Louise Taylor, one of the founders of Dermalux, a Warrington-based manufacturer of LED systems, some 1,000 clinics in the UK now use her company’s devices. “There is a feeling in the market that LED is something you can have on an ongoing basis,” she says. “Unless you have issues of photosensitivity, there are no real limits as to how much of it you can have, and that’s one reason why it is expanding in clinics.” But it is also the result of word of mouth, particularly on social media.

Rapid City pushes Downtown Lighting Project forward

The Rapid City Council approved the beginning stages of the Downtown Lighting Project. The project as it stands would fund 20 blocks of lighting upgrades costing $1.8 million. LED lights would be used to replace poles along Main and St. Joseph Streets from East to West Boulevards that have been in effect since 1991.

Are "smart" light bulbs a security risk?

"Smart" light bulbs promise energy efficiency and customizable features for homeowners, like remote-controlled mood lighting. But are they also a security risk? Maybe so, according to a recent study that explored how cybercriminals can use popular smart bulb brands to target people's personal information. The report — which looked at smart bulb brands including eufy, Geeni, LIFX, MagicLight, Nanoleaf, Philips Hue and Teckin — found that the devices come with their own risks when not properly safeguarded from cyberattacks.

The first multicolor-tunable light bulb

Make no mistake: The LIFX Candle Color revolves around a gimmick. But what an amazing gimmick it is! It’s not just color tunable, it’s tunable to multiple colors—simultaneously. That’s a clever trick I’ve never actually seen in the real world. To clarify, while most color tunable bulbs can cycle through colors one after another, you can set the Candle Color to emit independent colors from different parts of the bulb all at once. As the user, you use the LIFX app to essentially paint the bulb with whatever you colors you want, wherever you want them. You can even have parts of the bulb turned off altogether. The effect is striking and unique; there’s simply nothing else like it on the market (yet).

How age affects perception of white LED light

Although LEDs are increasingly used in low-energy lighting and displays, consumers sometimes find their light harsh or unpleasant. Findings from a new study point to the need to take age-related perception differences into account when designing white LED lighting that is more pleasing to the eye.

"Our study revealed that the amount of short-wavelength light a source emits together with the viewer's age may lead to very different perceptions of a white light," said the research team leader Aurelien David of Soraa Inc., Fremont, Calif., U.S.A. "LED light sources exacerbate this effect, because their emission often features large peaks of blue or violet radiation."

The researchers report the new findings in The Optical Society (OSA) journal Optics Express. They point out that although conventional colorimetry assumes all users have the same visual response, more recently developed models for color perception take age-related effects into account and can be used to predict and help mitigate differences in color perception.

Late kickoff, LEDs bring energy to already-bitter rivalry

The Alabama Crimson Tide has played only one night game inside Bryant-Denny Stadium in the last 712 days. The wait will come to an end with an added twist on Saturday when the Tennessee Volunteers visit Tuscaloosa. Over the summer, 60 colored LED lights were added atop Bryant-Denny Stadium, in addition to 174 white LEDs that replaced a 30-year-old set. The project, which was completed in mid-August, was designed to enhance the fan and game experience. The new lights include an instant on and off switch, and they are fully dimmable.

Blue Light from LEDs Can Rot the Brains of Fruit Flies, Study Finds

The blue light that emanates from every smartphone and fluorescent bulb isn’t thought to be great for our health, particularly the health of our eyes. But a new study in fruit flies suggests that blue light can even be harmful to brains and speed up aging—again, in fruit flies. There’s a very long way to go before we could assume the same is true for people. Researchers at Oregon State University kept some adult flies in a cycle of 12 hours straight of blue light exposure, then darkness for the next 12 hours. These flies were compared to control groups of flies that either got total darkness for the entire day or were bathed in light that had the blue wavelengths blocked.

Quickly designing a white LED

The advent of the white light emitting diode (LED), which consists of a blue LED with a phosphor layer, greatly reduces the energy consumption for lighting. Despite the fast-growing market, white LEDs are still being designed with slow numerical trial-and-error methods. A team of scientists from the University of Twente, Technical University of Eindhoven, and leading industry Signify (formerly Philips Lighting) have introduced a radically new design principle that is based on an analytical model instead of a numerical approach. The model predicts a white LED's color point for any combination of design parameters and allows for a much faster design, by up to a 1 million times, resulting in reduced design and production costs. The results are being published in ACS Photonics .

Energy-efficient light bulbs: The DOE is about to change the rules

In 2007, Congress passed the Energy Independence and Security Act, which mandated higher energy efficiency standards in the US. The law included new standards for light bulbs that were written to spur the lighting industry out of the incandescent age and towards new technologies like LEDs that use significantly less energy. But last month, the Department of Energy under President Donald Trump reined the news standards in by limiting the types of light bulbs to which they can apply. Those revised exemptions, which kick in Oct. 7, will protect the sale of certain kinds of incandescent light bulbs that might otherwise have come off the market in the coming months due to poor energy efficiency.

How to Force Long-Day Perennials into Flower with High-Intensity LEDs

Growers who force perennials into flower know they will fly off the bench at retail, as most perennials are sold without flowers. Consequently, growers are looking for easy and profitable forcing protocols to produce a wide variety of high-quality flowering perennials in the spring. Until recently, growers used incandescent lamps (INC) to provide low-intensity (~1 to 3 µmol∙m−2∙s−1) photoperiodic lighting to extend the day or interrupt the night. These lamps provided a low-red to far-red light ratio (R:FR) that induced long-day plants into flower. Unfortunately, a low R:FR can also result in unwanted stem elongation and stretching.

It’s a change that will likely save millions per year in utility costs. “LED lights make the streets brighter. Now why do we like this? I think it’s obvious to most people. A brighter street is a safer street - for pedestrians maybe crossing, for people driving down the street, and also to cut down on crime,” Mayor Caldwell said.

Cleveland bridge under lighting issues raise safety concerns

Some Cleveland leaders and community activists are concerned about bridge lighting outages they say could have a negative impact on safety. Community activist Henry Senyak pointed to light fixtures that are broken or are burned-out under multiple bridges on both the east and west sides of the city. Senyak said some of the lights posted under bridge over-passes have been out for several months and are a potential hazard for motorist, pedestrians and cyclists

Kuo: New ‘pro’ iPad models with mini-LED display coming

In a Chinese language report released by TF Securities’ Ming-Chi Kuo, the reliable Apple analyst repeats claims that Apple is working on new high-end iPad and MacBook models featuring mini-LED displays. The iPad and MacBook would use approximately 10,000 LEDs. This number would be far beyond above what the upcoming $6000 Pro Display XDR will use (around 570 for its backlight), with each LED being smaller than 0.2mm. Kuo believes that Apple prefers mini-LED style panels to OLED because the two technologies provide comparable color gamut, whilst the mini-LED technology is not as susceptible to image burn in.

How smaller lights could lead to big TV improvements

The latest new TV tech is called mini-LED, and it will be available for the first time in TCL's 8-Series, shipping this October. With the promise of better contrast, mini-LED could offer improved picture quality compared to "standard" LCD-based TVs, at a cheaper price than OLED TVs. We'll have to wait for the reviews to determine how well mini-LED actually performs, but even if it falls short of OLED, mini-LED is potentially a big deal. While TCL is first TV maker out of the gate with a mini-LED TV, it probably won't be the last. Mini-LED's advantage, aside from a snazzy new name, is that it's actually affordable. It's an evolutionary technology, not a revolutionary one, and draws on existing LCD TV technology.

City of Olean Is Replacing Streetlight Bulbs with LEDs

The city is in the process of replacing many streetlight bulbs with LED lights. The program has been authorized by the Olean Common Council and is being advanced by the mayor’s office. “It will be LED lighting instead of mercury-vapor that was out there before,” Olean Mayor William Aiello said. “There will be less energy consumed, and it’ll be cheaper to run the streetlights.” This effort to replace the streetlight bulbs with LEDs was prompted by National Grid, according to both Aiello and Alderman Linda Witte.
