LED Lighting Solutions Included in DesignLights Consortium® Qualified Products List Report

LED lighting solutions company, aeternusLED®, based in Blacksburg, VA, has entered the scene and put up some very impressive results while doing so. The aeternusLED® Dolfin II Series LED 2x2 luminaire set the mark for the category 2x2 luminaire for commercial spaces while emerging with best results in all measured criteria, including efficacy, light output, reliability, and lifetime. The now DLC certified aeternusLED Dolfin II series is offered in lumen packages producing 2,448 to 5,498 delivered lumens, from 22 to 55 watts used thus achieving an efficiency between 99.9 and 109 lumens per watt. aeternusLED luminaires are available with a wide range of color temperature options though tested at 4,000K. The certified L70 lifetime at 140,000 hours allows the aeternusLED Dolfin II series to be sold with an industry leading 10 Year Warranty. These factors combine to allow aeternusLED to stand alone at the top in this category.

With the results now on DLC’s Qualified Products List, aeternusLED® Dolfin II Series LED 2x2 luminaire bested all criteria. The QPL results validates the results from all the third party testing performed by accredited safety and performance laboratories. Every inch of the aeternusLED systems is patent pending technology, and the sum of the system parts as a whole unit, are what generate the results sought by many but unlocked by aeternusLED. The resulting light is glare free with no shadows and 162 degree light distribution. The reflective dome makes all this possible with the use of 98% reflective white optics and our custom lens material. Gary W Engelhardt developed the concept for the Dolphin II series troffer in 2012 and is focusing on the development of new technology to ensure aeternusLED will always be an industry leader that is truly “Made in the USA”.

What does the jargon mean for building owners, facility managers, and those responsible to lead green energy initiatives? AeternusLED luminaries last 2-3 times longer than many other LED products currently on the market, making the maintenance savings as valuable as the sought after energy reduction. Not only does AeternusLED have a corner on longevity but because of their higher efficacy, greater amounts of electricity are saved over longer periods of time without lamps, ballast or fixture replacements. The 10 year maintenance free warranty demonstrates aeternusLED’s plan to reach commercial sectors with high quality lighting products.

Monday Roundup: In 2018

This week: Packaged LEDs futures, Bayer does polycarbonate, and declining electricity use.

Electricity use projected to drop

We reported a month ago that electricity use in the US has declined for three years and stands at levels not seen since 2001. Now IHS Technology has released a projection on how much it might decline in the future, due to the uptake of more efficient lighting. The answer: a projected 24%, from 3.61 trillion kWh in 2013 to 2.75 TkWh in 2018. This will happen despite the expected 5.1% rise in the number of lamps worldwide. Lighting will account for 10.3% of all generated energy in 2018, versus 16.4% last year.

The coming scale of the Internet of Things

Someone has put a number on the size of the IoT over the coming five years. It's a big number. Business Insider Intelligence estimates that the IoT today encompasses 1.9 billion "things" and will balloon to 9 billion by 2018. That's on the same order as the combined total of PCs, smartphones, tablets, smart TVs, and wearable computers. The Internet had better be running predominantly IPv6 by then.

Packaged LEDs at $26 billion in five years

Continuing with the theme of five-year projections, we turn to Strategies Unlimited's extrapolation of the growth of the packaged LED business, unveiled in the opening keynote at Strategies in Light last week. Analyst Katya Evstratyeva said this segment grew 7% from 2012 to 2013 and will grow at a double-digit rate in each of the next five years to reach $25.9 billion in 2018. Lighting will account for most of the growth, with automotive growing only modestly, while backlighting and mobile applications will decline. Evstratyeva said that high-power LEDs will still dominate over mid-power in 2018. LEDs Magazine will post more details this week.

Take two lenses and call me in the morning

Designing luminaire optics giving you a headache? Bayer AG has just the thing for you, according to a press release that hit the wires when the SIL conference opened. Bayer MaterialScience produces "special polycarbonate grades for crucial LED components such as lenses and light guides," according to the presser. The product line is a couple of years old. I, for one, was unaware that the company had branched out from acetylsalicylic acid.

Where Have All the Wires Gone?

When someone says wireless in the context of lighting systems, they are typically talking about a control mechanism. But ultimately could we realize Tesla's dream of wirelessly transmitted power?

Having the LED Specialists offices in New York confers the advantage of being on the visit circuit for many suppliers in the lighting business. Not long ago, we had the pleasure of meeting with EnOcean, a manufacturer of wireless control systems, and it got me thinking.

"Wireless" in our industry usually means a lighting control system. It is implicit that the LED lighting source maintains its copper umbilical cord. There are concepts afoot to transmit power wirelessly and remotely, but so far they have not been very efficient, do not work for long distances, and might pose some health hazards. (Recently Steve Perlman of Artemis has demonstrated a wireless technology that holds the promise of decongesting cellular service in cities. Imran Akbar explains in detail why this tech may hold the key to practical wireless power transmission.)

Wireless control technology for a complex lighting system assigns each fixture a unique address. A master controller creates unlimited potential light scenes. It commands fixtures -- individually, in groups, or in unison -- much as a conductor would an orchestra. The controller communicates via a wireless protocol, such as ZigBee, Bluetooth, or WLAN, to establish contact and issue commands to the fixtures in its jurisdiction. Apps on personal electronic devices can interface with the controller to enable remote access.

The flexibility of LEDs facilitates adaptation in the lighting market. The ubiquitous fluorescent lamp does not like to dim, so there are very few office environments that dim. Dimming is a piece of cake for LEDs. Since it's easy to combine white LEDs with color LEDs, color-changing scenarios are also easy.

Blue-sky scenario

Imagine, in the not too distant future, getting to work early in the morning, greeted by office lighting that simulates the orange glow of a sunrise. You're momentarily confused. Did you just walk in to your office, or out? As the day unfolds, the color temperature in the office changes from warm white to cool white, as though the ceiling were the open sky. Perhaps this lighting system even simulates the position of the sun, casting shadows to the west in the morning and to the east in the evening. How about a subtle hint of weather? I'm not sure what would be better on a dreary, snowy, or rainy day here in my home state of New York, simulating actual cloud movements and overcast gloom, or imitating a dazzling Hawaiian sky. Yeah, like that's a tough choice.

There could be unique scenes for lunch time, corporate events, welcoming special guests, or for demarking zones in a facility (such as ESD-sensitive, or safety zones surrounding potentially dangerous equipment). Holidays could contain suggestions of their distinctive colors. St Patrick's Day could have a hint of green, Valentine's Day red, and the Fourth of July red, white, and blue. Potential scenes are literally infinite, as are the applications.

This office lighting system could augment an emergency lighting system to enhance safety. Picture a moving light pattern that guides occupants to the exits in low-visibility conditions (like the carpet in the partnership of Philips and Desso).

This is all possible today, thanks to wireless standards, controls, and protocols. Technically it is all achievable with wired systems, but in actuality the effort to install the wiring, especially as a retrofit, would dissuade all but the most determined.

Dipping a toe in EnOcean

The EnOcean protocol is much simpler, and intended for different applications. It targets non-continuous transmission, ultra-low power, energy harvesting, and fairly simple applications, such as interaction with switches and sensors. One feature I found particularly interesting is the EnOcean wireless switch. The act of depressing the switch transfers enough energy for the switch to send out its brief command.

So, now we have wireless control, but there's still a long way to go before we see the last of the copper conductor. Next in line, wireless energy transmission!

Taiwan Provides Financial Assistance to Caribbean Island for Installation of LED Lights

Permanent Secretary in the Ministry of Energy, Mr. Lennie Lake said the money will be used to purchase 110 LED lights to be installed in the Frigate Bay area from Sugars Complex to Zenway Boulevard as well as the New Road Community Park.

“Installation will be a collaborative effort between the Public Works Department (PWD) and the St. Kitts Electricity Company (SKELEC),” said Mr. Lake.

Taiwan in partnership with the Ministry of Energy and the St. Kitts Electricity Corporation (SKELEC) installed over 40 LED light poles on the Kim Collins Highway and that stretch of road from the Eastern Caribbean Central Bank (ECCB) eastwards to the Sugar’s Complex.

<span style="font-size:10.5pt;Helvetica" ,"sans-serif";color:#6b6e80;"="">Taiwan also financed the installation of solar lights on the island main road from Sandy Point to the Robert L. Bradshaw Memorial Park in St. Paul’s, installation of a one-mega watt solar farm at the Robert L. Bradshaw International Airport and Government Headquarters.

Understand the true cost of LED choices in SSL systems

The solid-state lighting (SSL) industry has focused on LED component cost as the key to lower upfront costs for LED-based lighting and broader deployment. And indeed lower LED prices are important for broader SSL adoption. Still, there can be hidden system-level costs and reliability issues tied to the selection of LED components, which SSL developers must understand to deliver products that perform well at install and throughout an extended life. Lengthy LM-80 testing of components is paramount to robust lighting products. Let's examine some background on LED manufacturing and trends, discuss SSL application requirements, and then consider how the hidden cost of LED components can impact the success of a general-lighting product.

LEDs turn out the light on incandescents and CFLs

Most people have accepted that it's all but over for old incandescent bulbs. But CFLs—compact fluorescent bulbs, the titular replacements for incandescents—may be rapidly becoming extinct as well. LEDs or light-emitting diode bulbs are the next lighting generation, and they've made significant advances in the last couple of years. I've been testing dozens of bulbs from companies such as Cree, GE, Lighting Sciences, Sylvania, and Toshiba, and found that not only are LEDs a better alternative with superior lighting characteristics, they offer more features than any previous lighting technology—as long as you understand how they are rated and what to look for.
