LEDs Are An Important Climate Change Solution

By: Diane MacEachern Founder & CEO, Big Green Purse

The People's Climate March raised awareness about how important it is to find and use technologies that will help save energy, reduce carbon dioxide emissions, and start to reverse climate change. One of the most promising and affordable technologies is LED light bulbs, also known as LEDs.
WHY SHIFT TO LEDS? The Three P's...
Making the shift to energy-efficient lighting offers big benefits for people, the planet and our pocketbooks.
PEOPLE -- LED bulbs help reduce air pollution, making the air healthier to breathe for kids and others who suffer from asthma, heart disease and many respiratory ailments.

• Reduce air pollution -- Most household energy still comes from coal-burning power plants. About 12 percent of the energy we use at home powers our lighting -- from ceiling fixtures and under-counter lights to table and bedside lamps. An LED bulb uses 70-90 percent less energy than a standard bulb, limiting the need to burn that much more coal.

PLANET -- Speaking of energy, if every household replaced just one light bulb with one certified by the federal Energy Star program, we would save enough energy to light two million homes for a whole year.

• •Reduce climate change -- We would also prevent greenhouse gas emissions equivalent to that of 550,000 vehicles. LED bulbs are a terrific way to fight climate change.

POCKETBOOK -- Any time we save energy, we save money. Though an LED bulb costs a little more up front, it can save $80 in electricity costs over the lifetime of the product.
PLUS -- LED technology is so efficient, one bulb can last as long as 22 years or 25,000 hours. That's particularly convenient for hard-to-reach places like ceilings and outdoor fixtures.
WHAT LED BULB SHOULD YOU CHOOSE?
As with other bulbs, you can get LEDs that provide different amounts of light. LEDs provide light in lumens, while incandescents are sold according to how bright they are in terms of watts. Most LED bulb packages will give you the wattage the LED is replacing. For example, this LED bulb replaces a 60 watt incandescent.
In addition to the light of the bulb, the label makes a difference. Most people who go shopping for an LED bulb probably look for the words "energy-saving," which any company can slap on any bulb. What they really need to be looking for is the Energy Star label. Bulbs that have earned the Energy Star save significant amounts of energy and money because they are independently certified to use less energy, undergoing extensive testing to ensure high quality and the performance you expect. These three funny videos make clear why certified LED bulbs are more effective than non-certified bulbs.
With 70 percent of U.S. light sockets still containing inefficient bulbs, the potential is huge for American consumers to find lighting options that save them energy, money and help protect the environment from climate change. LED bulbs are quickly gaining steam as the most innovative and long lasting alternative to incandescent bulbs.
Disclosure: I am a long-time advocate of energy efficiency and technology like LED bulbs. I am working as a consultant on this project to help educate the public about the value of Energy Star LED bulbs in the fight to stop climate change.

Cree adds COB LEDs in high-density product family for directional SSL (UPDATED)

Published on: February 12, 2014

By Maury Wright
Editor, LEDs Magazine and Illumination in Focus

 

 

  

 

 

Cree has announced the CXA1310, CXA1850, and CXA2590 chip-on-board (COB) LEDs with light-emitting surface (LES) diameters of 6, 12, and 19 mm. respectively. The products are part of Cree's COB offering that the company terms high density and are designed to maximize the candela (cd) per dollar for directional applications, as opposed to the standard-density products that are focused on maximum lumens per dollar.

Cree first announced the high-density concept back in September of 2013 with the 9-mm CXA1520 that offered double the output of the prior Cree LEDs in the same size. The new products extend lumen output to beyond 13,500 lm at 5000K CCT and to 11,500 lm at 3000K CCT. The 6-mm CXA1310, meanwhile, delivers flux in the 2000-lm range. Cree says that the performance is industry best relative to the LES sizes, and a smaller LES enables simpler, lower-cost control of the beam with smaller optical elements such as reflectors.

The LEDs are available across the range of 2700K to 6500K CCT. Cree offers 80-CRI products across the board, 70-CRI products at the cool end of the spectrum, and 95-CRI products at the warm end of the spectrum.

With the new product launch, Cree also stressed a new way to consider LED performance, and the match of LEDs to an application, called optical control factor (OCF). Essentially the metric comes down to performance divided by surface area of the emitter, whether the LED or LEDs under consideration are in COB array or discrete form.

Paul Scheidt, product marketing manager for LED components at Cree, discussed applications and LEDs relative to OCF. He said applications such as linear troffers can benefit from mid-power LEDs that have low OCF that is a match for the broad beam spread, diffuse light requirements of the application. He said Cree's mainstream CXA family is also a good match to other applications with diffuse light requirements such as BR lamps and downlights.

The high-density COB LEDs are targeted at high OCF applications including directional lighting ranging from PAR/MR LED replacement lamps to tracklights to even low- and high-bay fixtures that need to focus the beam. Primarily, the LEDs target applications that require maximum center beam candle power and enable system performance legacy sources can't serve.

"Never before have we been able to harness such a large amount of light in such a small package, which can help us improve our lighting designs and address a number of applications that we previously could not, " said Mike Wang, vice president of lighting engineering at Edison Price Lighting. "The beauty of these new high-density LED arrays from Cree is that they are helping us bring products to the market that currently don't exist."

Product prototype comparison

To illustrate the advantages of the new products, Cree has assembled some prototype light engines to which it compared existing lighting fixtures and lamps based on legacy sources. For example, Cree has demonstrated a CXA1310-based engine that delivers 31,000-cd CBCP and a 9° beam at 15.4W. Scheidt compared that product to a typical track fixture that uses a 44W Philips PAR20 ceramic metal-halide (CMH lamp) that delivers 13,220-cd CBCP and a 10° beam.

In fairness, the Philips CMH lamp is 86 CRI and the Cree prototype is 82 CRI. But the performance advantage of the LED option is clear. Scheidt said that a quality track fixture sells for $200 in high volume and the lamp for around $20 with those prices doubled if bought in individual quantity. He said that the bill of materials for the LED light engine was in the $34 range in high volume including LED, driver, heat sink, and optic. Of course, the track fixture includes a ballast and that component is equivalent to the driver in the LED light engine. But the point is that a track luminaire can easily accommodate the cost of the LED light engine and deliver superior performance.

The comparison ignores the fact that the LED light engine would still need to be accommodated in a fixture, but still shows the value proposition of the higher-performing and more-efficient LEDs.

Scheidt also stressed that the LED implementation delivers performance that is simply unavailable in legacy sources. He said that the very best PAR20 CMH lamps top out at 2000-cd CBCP. Yet the LED prototype offers more than 50% additional performance even though the actual lumen output of the CMH lamp is greater.

Another prototype LED engine in Cree's portfolio is based on the 21-mm CXA1850. Scheidt compared a 3000K, 55,620-cd CBCP, 38W LED product with a typical track fixture equipped with a Philips 74W, 50,559-cd CBCP CMH lamp. The Cree prototype used an off-the-shelf Nata optic that Cree had on hand to deliver a 15° beam whereas the Philips lamp delivered a tighter 10° beam. At first glance it would appear that the CMH product is higher performing given the narrower beam. But Scheidt pointed out that the LED engine would have even a higher CBCP spec if equipped with a reflector that narrows the beam. The largest CXA2590 LED, meanwhile, can deliver the equivalent CBCP of a 150W CMH source at almost half the power.

"The high-density LED arrays from Cree are extremely impressive," said Kenny Eidsvold, president of Intense Lighting. "We are looking forward to using these products in applications requiring very high center beam candle power that previously could not be achieved with LED-based solutions."

Bridgelux announces LED-based module to speed outdoor development

Published on: March 27, 2014

By Maury Wright
Editor, LEDs Magazine and Illumination in Focus

 

 

  

 

 

Bridgelux has announced the Outdoor Lighting Module (OLM) LED-based product family meant to accelerate the development cycle for manufacturers working on outdoor-lighting products. Bridgelux said that the weather-tight module with integrated optics can reduce solid-state lighting (SSL) development time by three to six months and cut $100,000 in R&D expenses.

With the OLM, Bridgelux is targeting roadway, parking, industrial, and other outdoor applications. Each module integrates two Bridgelux Vero Series chip-on-board (COB) LEDs with a custom-designed optic covering each LED. The company will offer six versions of the OLM with flux output ranging from 2000 lm to more than 4000 lm and a choice of 4000K or 5000K CCTs. Product developers can combine as many as three of the OLMs in a single fixture design enabling the six base models to support luminaire designs that can replace 70W to 250W HID lighting.

The OLM is not Bridgelux's first foray into outdoor modules. Back in early 2012, Bridgelux developed a module based on one of its LED arrays in a large discrete package and supplied the product along with exclusive partner Chevron Energy Solutions to retrofit projects. Bridgelux said that since the retired design still serves in a number of projects although the exclusive relationship with Chevron is over. Moreover, a spokesperson said, "The knowledge gained from that previous experience was invaluable in the development of the new Bridgelux OLM Series, which will be available through broad distribution."

Modules in general can accelerate the SSL development process by handling the LED integrations, mitigating thermal issues, and in this case including optics that can form the desired beam patterns. For outdoor lighting, however, the fact that the OLM is also IP-66 rated against water and dust ingress takes considerable burden off the development team that needs to ensure reliable operation in harsh conditions. Brad Bullington, Bridgelux's CEO, said, "We are now introducing the industry's most advanced and sophisticated LED sub-system for outdoor applications."

The OLM is based on a Vero 10 LED that enables system efficacy ranging from 96-124 lm/W. A COB LED is a compromise in an outdoor-lighting design. Without question a carefully-crafted luminaire that uses small LEDs and total internal reflection (TIR) lenses can deliver more precise beam patterns. That said, we expect more outdoor lighting products to use COBs because they are much simpler to design into luminaires and provide performance that is suitable in many applications. The Bridgelux design uses the combination of a reflector and diffuser lens to control the beam. For more information about beam patterns see "SSL luminaires must deliver reliable beam patterns in outdoor applications."

Bridgelux said that the modules will be available beginning in June for customer shipments. The subsystems range from 14W to 40W in power consumption. Bridgelux is rating the modules for minimum 50,000-hr lifetime.

When do you want to go to Camotes Islands?

Visit Camotes Islands this summer.

Sweet potatoes.
That’s where this island supposedly gets its name from.

Legend has it that Spaniards who arrived here came upon some natives farming. When asked what the island’s name was, the natives replied “camotes” (sweet potatoes), thinking they were being asked what they were harvesting. This is just one of the charming things about the Camotes Islands.

The Camotes Islands are made up of the islands of Pacjian, Ponson, Poro and Tulang. Collectively, they are called “The Lost Horizon in the South” because of their unspoiled beauty. And once you sink your toes into the fine white sand here, it’s easy to see why. Beaches like Santiago Bay and Mangodlong, with glistening waters and relaxed shores, are excellent places to swim and sunbathe undisturbed.

Further inland, Pacjian is home to the serene 700-hectare Lake Danao. Dubbed “Lover’s Lake” for its seclusion, Lake Danao is the biggest natural lake in Cebu. Enjoy a boat cruise, hike and picnic, or go bird-watching to catch species like the purple heron and the Philippine wild duck.

Raring for some adventure? Check out Bukilat Cave in Tudela. Beneath its rough exterior lie imposing stalagmites and stalactites, as well as an icy-cold pool believed to originate from an underground spring. This entire cave system is illuminated by natural skylights.

Another stunning subterranean secret is the challenging Timubo Cave in Sonog, where you need to make your way down a winding staircase to reach the clear waters within.

Life here may be slow-paced, but the islands do hold several festivals. The Tagbo Festival in January celebrates the founding of the town of Poro, through a re-enactment of the reconciliation of two warring tribes.

The Soli-Soli Festival, held every third Sunday of March in the town of San Francisco, is a creative tribute to the soli-soli plant – a source of livelihood for the locals. This festival also serves as a thanksgiving to the town’s patron saint.

Scientists Build Thinnest-Possible LEDs and Find It To Be Stronger, More Energy Efficient

Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy efficient.

  University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics. The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.

“We are able to make the thinnest-possible LEDs, only three atoms thick yet mechanically strong. Such thin and foldable LEDs are critical for future portable and integrated electronic devices,” said Xiaodong Xu, a UW assistant professor in materials science and engineering and in physics.

Xu along with Jason Ross, a UW materials science and engineering graduate student, co-authored a paper about this technology that appeared online March 9 in Nature Nanotechnology.

Most consumer electronics use three-dimensional LEDs, but these are 10 to 20 times thicker than the LEDs being developed by the UW.

“These are 10,000 times smaller than the thickness of a human hair, yet the light they emit can be seen by standard measurement equipment,” Ross said. “This is a huge leap of miniaturization of technology, and because it’s a semiconductor, you can do almost everything with it that is possible with existing, three-dimensional silicon technologies,” Ross said.

The UW’s LED is made from flat sheets of the molecular semiconductor known as tungsten diselenide, a member of a group of two-dimensional materials that have been recently identified as the thinnest-known semiconductors. Researchers use regular adhesive tape to extract a single sheet of this material from thick, layered pieces in a method inspired by the 2010 Nobel Prize in Physics awarded to the University of Manchester for isolating one-atom-thick flakes of carbon, called graphene, from a piece of graphite.

In addition to light-emitting applications, this technology could open doors for using light as interconnects to run nano-scale computer chips instead of standard devices that operate off the movement of electrons, or electricity. The latter process creates a lot of heat and wastes power, whereas sending light through a chip to achieve the same purpose would be highly efficient.

“A promising solution is to replace the electrical interconnect with optical ones, which will maintain the high bandwidth but consume less energy,” Xu said. “Our work makes it possible to make highly integrated and energy-efficient devices in areas such as lighting, optical communication and nano lasers.”

The research team is working on more efficient ways to create these thin LEDs and looking at what happens when two-dimensional materials are stacked in different ways. Additionally, these materials have been shown to react with polarized light in new ways that no other materials can, and researchers also will continue to pursue those applications.

Mandrus of the University of Tennessee and Oak Ridge National Laboratory; Takashi Taniguchi, Kenji Watanabe and Kenji Kitamura of the National Institute for Materials Science in Japan; and Wang Yao of the University of Hong Kong.

The research is funded by the U.S. Department of Energy, Office of Science, the Research Grant Council of Hong Kong, the University Grant Council of Hong Kong and the Croucher Foundation. Ross is supported by a National Science Foundation graduate fellowship.

Spotlight 2014: LED lights installed to save energy, money at Port Authority facilities

The lighting seen here inside the Lincoln Tunnel has been replaced by energy-efficient LED lights, which Port Authority says will save $283,000 annually for 15 years, the life of the lighting. Port Authority has replaced lighting at a number of New Jersey-New York crossings, including the George Washington Bridge. Journal file photo

 

 By The Jersey Journal
on March 20, 2014 at 6:00 AM, updated March 20, 2014 at 6:24 AM

In a move that the Port Authority says will save $283,000 in energy costs a year, the bistate agency has replaced the lighting in the Lincoln Tunnel with 2,300 energy-efficient LED lights.
“Replacing our bridge and tunnel lighting systems with new LED lights makes business sense and benefits the environment by reducing our energy consumption,” P.A. Executive Director Pat Foye said. “Our investment... is just one example of the myriad of efforts this agency undertakes to attain our sustainability goals.”
The $2.1 million project, which began early this year, consists of 45-watt LED lights that will reduce electricity use by an estimated 1.2 million kilowatt-hours a year, Port Authority officials said. They expect a savings of roughly $1.3 million a year with the replacement of the lighting at the Port Authority Bus Terminal, the Journal Square PATH station, the George Washington Bridge and the Holland Tunnel.
The lights at the Holland Tunnel were replaced last year, and in 2009, the George Washington Bridge became the first bridge of its kind in the metropolitan region to have a full strand of LED lighting.
“Our agency has a steadfast commitment to make our operations more sustainable and environmentally sound,” P.A. Deputy Executive Director Deborah Gramiccioni said.
