New Colorful LED Mood Lighting Sets the Mood for Weight Loss

It isn’t groundbreaking news to say that lighting affects mood. This is why you’ll never see someone arrange a romantic date night with rose petals, a bottle of wine, and 1000W metal halide lamps. It’s also why you don’t see too many candlelit jewelry stores. We want different things from our lights, and every kind of light can be used to set a particular kind of psychological precedent.

With the development of LED technology, we are discovering precisely how lighting affects behavior. Why do grocery stores use the luminaires they use? What about restaurants and offices? To answer some of these questions, I will spend the next few posts focusing on some trends in LEDS that reveal some of the unseen workings of “mood lighting.”

Red LED Lighting Used in Weight Loss

A doctor in Boca Raton, Florida, is pioneering a way to use LED lighting to encourage weight loss. Dr. Sasson Moulavi is using a technique called Near Laser Assisted Lipolysis (NLAL) to assist people who are struggling to lose weight by traditional means.

The NLAL process involves strapping red LEDs to the patient for a designated amount of time. The patient then removes the LEDs and exercises for twenty minutes. The treatment, combined with a calorie-focused diet, allows patients to lose weight even after hitting a plateau with their regular diet and exercise regimen. Dr. Moulavi and others say that the light penetrates the skin and weakens the walls of fat cells; the fat then breaks through the weakened walls and travels to parts of the body where it can be more quickly burned off. The exercise phase of NLAL treatment attempts to fight the fat while it is in the vulnerable state.

Don’t buy it? I’ll admit—I’m right there with you. I can’t say I’ve signed up for a treatment session myself (though I could certainly use some trimming). Maybe NLAL is actually capable of penetrating fat cells; then again, maybe it isn’t. All I can say at this point is that Moulavi’s patients are seeing results—whether by tangible, physical impact on cells or the all-powerful placebo effect, believers of NLAL are shedding pounds and inches. Moulavi says he’s seen patients lose about 15 pounds a month.

Fast food restaurants often use bright lighting in their designs to encourage people to order and eat more. This study, by experts at Cornell University and the Georgia Institute of Technology, found that bright lighting actually increases the amount of food people will eat. The lights even have an effect on our psychological state when ordering—staring up at a brilliant, colorfully lit board of burgers, pictures, and flashy “Dollar Menu!” cues makes us more likely to impulsively order enough food to, well, super-size ourselves. Contrarily, calmer lighting at lower Kelvin temperatures (more popular in fine-dining establishments) encourages us to deliberately review each item on a menu and make sure what we’re ordering is exactly what we want.

So now I ask: Have you ever seen the inside of a fast-food joint lit up in blue lighting? Probably not. Researchers at the University of Arkansas may now know why. Blue LED lighting, they found, functions as an appetite suppressant. Their experiment placed subjects in booths randomly lit by white, yellow, and blue LED lamps. Diners were given a large breakfast and asked to rate their satisfaction with the food. The researchers then measured how much food was left on each person’s plate.

blue-led

The study found that men who were served under blue lights ate less than men served under yellow or white lights, even when all three groups were equally satisfied with their food. Oddly enough, though, the study found that women ate the same amount regardless of the lighting. Researchers guess this may be because men’s appetites are more tied to sight-based cues than those of women, which are more commonly dictated by the sense of smell.

The Future of Lighting and Health

Previously, I’ve discussed human circadian rhythmsdaily body cycles that are affected by the lighting in an environment. It is no surprise, then, that LED lighting can be used to persuade our psychologies and bodily functions. As LED trends develop, we will be able to learn more about how lighting can be used to further our health and wellness.

What do you think? Can we use LED technology to affect our health? Beauty? Psychology? Let me know what you think.

LED Gunshot Monitoring: Protecting Neighborhoods One Light at a Time

In a previous blog, I discussed the effect of nighttime lighting on urban crime rates. Studies have shown that, despite many people’s expectations, lighting levels do not necessarily affect an area’s safety or the amount of crime. They do, however, affect our perception of safety; most people feel safer in well-lit areas. To instill this sense of safety and lower energy costs, many cities have begun replacing traditional street lighting with amber LED lighting, which provides sufficient visibility for pedestrians and vehicles but is more efficient and less intense than other lights. But can our street lighting do even more?

While it would be unreasonable to expect lighting to eliminate crime entirely, recent progress in LED technology may be able to help. I’m talking specifically about gun violence here, which accounts for thousands of US deaths every year. So far in 2015, there have been over 10,000 gun-related deaths and over 40,000 incidents involving guns. GE Lighting is joining forces with SST, Inc., a security company, to implement something called the ShotSpotter Gunshot Location and Detection System. The technology would provide reliable information on the time and location of gunshots, which authorities can now only provide about 10% of the time. The two companies have entered into a memorandum of understanding (MOU) to install ShotSpotter technology into GE’s software- and sensor-enabled LED streetlights.

Gunshot Detection Technology Combined with LED Lighting

ShotSpotter uses acoustic sensor technology to detect when and where gunshots occur. If combined with the right software, ShotSpotter could analyze data and send results to law enforcement and first-response agencies.

This is where GE Lighting comes in. Earlier this year, GE introduced the Intelligent Environments for Cities platform—a fancy name for their series of data-sensor-equipped, cloud-based LEDs. GE’s lights can also transmit data on weather and light conditions, parking availability, environmental hazards, and be equipped with video monitoring and public-address systems. San Diego, CA, is one of the cities already using GE LED technology; they’ve reported a savings of more than $350,000.

With ShotSpotter’s gunshot monitoring technology, GE’s intelligent LEDs can each be part of a revolutionary network of responsive, data-collecting devices. Installing this network in a violent neighborhood would provide an automated, 24/7 neighborhood watch program.

Reliable and Immediate Information for First Responders

Law enforcement and emergency responders often lack immediate and reliable information about shootings. Individuals in neighborhoods plagued with frequent gun violence are often reluctant or unable to report information on shootings. Oftentimes, those who do report a shooting can only provide incomplete or incorrect information.

Installing sensor technology into LED lighting helps close this information gap and makes it possible for police, ambulatory services, and other first responders to assist gunshot victims and apprehend suspects. The LEDs would be able to collect data on incidents including the number of shots fired, the number of shooters, and the precise location from which shots were fired. Almost immediately after bullets are shot, information can alert dispatchers or specific responders, similar to alarm notification software many companies are already using. Over time, the data would be able to show, specifically, where these crimes are happening and where law enforcement would be most effectively deployed.

LiFi Brings Us One Step Closer to the Internet of Things

The collaboration between GE Lighting and SST demonstrates how LED lighting offers much more than illumination. LEDs in LiFi, which is basically WiFi transmitted through the visible light spectrum, could turn every streetlight into a technological node; a web of these nodes across a city would act like an interactive, communicative web of information.

As ShotSpotter and GE continue to roll out their plans for the lights, experts are exploring the other applications of their technology. Streetlights wired with both ShotSpotter and LiFi technology have the potential to alert mobile users within a specific radius of a shooting, giving them a chance to find cover. Similar alerts could be sent to alert users about extreme weather, heat, or cold.

Do you think ShotSpotter technology would have a positive impact on urban crime rates? Let me know below!

OEM and ODM Production Management Finds Solutions

Outrace is an emerging LED producer and expects to become more involved in the global LED market through this partnership with Factory Without Borders. It is one of the largest OEM/ODM LED light manufacturers in the world (i.e., They are one of the largest companies that designs and manufactures their own LED equipment and products). Initially, the company plans to focus on the United States and Brazil, as they have the highest concentration of LED producers. However, they have begun conducting research in Singapore and Taiwan as well as other countries who have begun to increase their need for LED products.

Asia in Race to Replace Lighting

Asia is the latest market to see significant growth in the LED lighting industryits businesses and residences have begun replacing incandescent bulbs with more energy-efficient LED lighting. In Malaysia, 6,000 people participated in the very first Light-Emitting Diode (LED) night run. The event was organized to encourage Malaysians to switch to LED lights, calling them “magical” when compared to incandescent lighting. In addition to the night run, The Marathon Shop organized workshops on the technical aspects of LED technology while also managing water stands along the route.

LED lighting has become increasingly more popular than incandescent lighting over the past few years. With the addition of real-time production and delivery management, it is expected that the increased global use of energy-efficient lighting will continue.

Endangered Birds Are Wounded by Deadly Light Pollution in Hawaii

Misdirected lighting from an Air Force Base in Hawaii is causing birds to literally fall from the sky. While we’ve long known that light pollution can impact avian life, the severity of that impact is now becoming clear. Fortunately, lighting technology is developing faster than ever before, so solutions are available.

Misdirected Lighting and Its Effect on Birds

More than 126 birds have recently fallen around Hawaii’s Kokee Air Force Station. Ten of them have died. Affected birds include Newell’s shearwaters, a threatened species, and the endangered Hawaiian petrels. Birds flying over the base seem to be distracted by the combination of bright lighting and foggy weather, which causes them to crash into objects or fly, confused, until exhaustion. The US Air Force has redirected their lighting fixtures and the number of incidents has already declined.

 

Light Pollution Alters Birds’ Daily Lifecycles

Left: Photo of sky in a rural area with minimal lighting. Right: Photo of sky in an urban environment with the telltale “glow” from light pollution.

The phenomenon in Hawaii is emblematic of a larger problem concerning birds and night light. Birds, just like humans, have circadian rhythms that govern their daily biological cycles. Excessive night light alters these rhythms and disorients feeding schedules, reproductive cycles, directional awareness, and more. A study published in the Journal of Pineal Research found that animals with disrupted circadian rhythms (catalyzed in this case by an overexposure to artificial light) also struggle to produce melatonin, which can lead to an increased production of fat, a higher likelihood of heart disease, lower metabolism, risk of hypertension, etc. Urban areas are particularly problematic for birds because the bright lights make it tough for them to differentiate between daytime and nighttime. Scientists stress that birds cannot function normally in habitats where natural lighting has been so severely altered.

 

 

Amber LEDs May Accommodate Wildlife

Although the proliferation of night lighting has caused this problem, lighting technology offers solutions. There are full lines of wildlife-friendly LED lighting available. Amber LEDs, for example, operate at a wavelength that does not disrupt the flora and fauna around it, but provides enough light to illuminate a given area. Companies like the one linked to above offer reflectors that prevent light from reaching anywhere it isn’t needed. The amber lights also have the energy-saving perks of LED lights; Energy.gov notes that “LEDs use 20%–30% of the energy and last up to 25 times longer than traditional incandescent bulbs.”

Your turn. Will LED lighting be enough to prevent interference in the lives of wild species? What other measures do we have to take to protect animals from light pollution? Share and tweet this article with your thoughts—I’ll follow up.

Across the Board, Racehorses Do Better with LED

While it’s well-known that LED lighting is cost- and energy-efficient, some British stable owners observe that LEDs may also improve the physical health and well-being of their racehorses, too.

Lighting Decisions for Horse Facilities

Farmers and riders have long experimented with horse barn lighting options. There are obviously a number of requirements for these kinds of lamps—not only do they have to provide high-quality light, but they must be watertight and extremely corrosion-resistant.  While the T5HO vapor-tight high bay fixtures are often recommended for horse barn lighting, it may be time to consider a new-technology upgrade.

Keith Foster, who owns Exhibition Seeds, and Stephen Fry, of HydroGarden, suggested full-spectrum LED lights. They recommended the lights be put into two horse stalls at Phil Kirby’s Sharpehill Stables in North Yorkshire, England, and Kirby agreed. Kirby installed the LEDs in two of his horse stalls, leaving them on from 5:00 AM to 9:00 PM each day for six weeks. They haven’t looked back since.

LED Success in the Stable

After just two weeks, both horses required an increase in daily food rations, and Kirby noticed clear improvements in each horse’s skin, muscle tone, appearance, and gallop. Kirby told HydroGarden that the two horses with LED lights in their stalls performed better than the other horses relying  on what little natural light was available.

The Science Behind LED Effectiveness

LED lights promote the release of adenosine triphosphate (ATP), which carries energy to cells. When the ATP level of each horse was increased, cells could more efficiently use nutrients and eliminate waste. This benefited every aspect of each horse’s health. Similar studies in Italy and Singapore found that LED lights can improve the body’s ability to heal muscle strains and wounds, too.

LED-lighting-in-stable-atmosphereIncreasing LED Lighting During the Winter

Unfortunately, Kirby had to stop the LED trial short when summer approached, as the horses needed softer ground for running than what was available in the region. Kirby plans to add the LED lights to two additional stalls in the coming fall to give the horses the full effect of the lighting through the winter months, when natural light is harder to provide. He also plans to use the lights from October to March on foals and yearlings with the hope that the young horses will achieve better size.

Human Applications of LEDs

Given how well the racehorses responded to the lights, it isn’t too surprising that humans can benefit from LEDs as well. Not only have LED “tail lights” been utilized to increase the safety of horses and their riders, LEDs help regulate our circadian rhythms, keeping us and our horses in competitive, performance-ready condition.

Lighting the Way to a Healthier Future

We’ve only just begun to explore the benefits of LED lights, but we expect them to work just as well for horses as they do for humans. I have a feeling the equestrian community will soon see that LEDs are an easy way to help their horses (and save owners some money, too).

Would You Bet On It?

Do you believe in the possibilities of LEDs as much as I do? Would you be more willing to bet on a horse that had been exposed to LED barn lighting?

On the Catwalk: LED Technology and High Fashion

Fedoras. Meat dresses. Handlebar mustaches. Full-body sweaters. Whatever these are.

The world of fashion has been known to make some wild (see: questionable) decisions, and I won’t pretend to be able to keep up with every new trend that hits the runway. However, there is one brilliant fashion choice that has grabbed my attention: LEDs.

Believe it or not, there is actually remarkable work being done out there to make light-emitting diodes wearable. Rapid technological reforms and the continued miniaturization of LED lighting have allowed LEDs to be embedded directly into fabrics to create myriad new possibilities.

Already, there are markets for dresses with hundreds of ingrained, color-changing LED lights and for those with waves of LEDs that create moving patterns along the fabric. This impressive LED catsuit already exists. The cool, low-voltage, and subtle luminosity of LEDs can make an article of clothing stand out, yet allow its wearer to maintain some kind of social decorum.

Making a Statement, Literally, with LED Clothing

There are already shirts, dresses, jackets, etc., that can be connected to smartphones to display text and messages from social media. At sporting events, concerts, trade shows, and other events where people need to share messages (“I <3 Dr. Bulb,” for example), LEDs can now transform anyone and everyone into a walking message board.

Imagine a model casually walking through a convention center with an LED blouse directing potential customers to a particular booth, or another who can display the products a company has to offer. Apparently, LED-lit mouthguards have even made their way into overseas marketing campaigns. With a little creativity, wearable LED technology can be both eye-catching and informative, if not perfect for spreading good vibes at your favorite music festival.

LED Illumination with Purpose

The future of LED clothing is limited only by the imagination of its designers and users. There are already articles of clothing that change color with the touch of a sensor and others that can get lighter or darker based on how warm it is outside. This is just one way LEDs cleverly merge function with fashion.

In the near future, a runner may be able to don a jogging suit that displays his or her heart rate, hydration rate, blood pressure, etc., on their sleeves. In hospitals, patients could wear sensored clothing that would not only show their vital information, but also alert doctors of an emergency if those vitals start to decline.

Big Names in LED Fashion

The LED clothing barrier has already been breached by celebrities such as Katy Perry and Taylor Swift. Tay-Tay (that’s what the kids call her, right?) has in the past adorned herself, her backup dancers, and even the props in their hands with hundreds of LED lights. As the technology becomes more affordable and versatile, we can expect illuminated clothing to be adopted by other celebrities and, maybe, the rest of us, too.

What Do You Think? Would you wear LED clothing? Besides hospitals and athletes, can you think of any other applications for LED clothing? Throw me a few ideas in the comments below!
