Museums Shifting to LEDs to Protect Precious Paintings

exhibition-362163_1280As museums around the world look to protect some of the most famous paintings from artists like Vincent van Gogh, few realize the harm that light can have on the darkening of bright colors in these iconic paintings. The yellow pigment used specifically by van Gogh has darkened so noticeably over time that other artists have started using other pigments entirely.

Museums Switching to LED Lighting

As companies look to not only save money, but also better protect their paintings, they’re looking to LED lighting in droves.

Scientists have identified the colors of light that are most damaging to paintings, which are typically blue and UV light. In the past, art museums would put UV filters over their incandescent bulbs, but LEDs make it much simpler by not emitting UV light at all.

LED Innovations Leading to Less Damage to Paintings

However, LED light is still light and, therefore, can damage paintings. Scientists have therefore been working hard to find ways to minimize this damage. One way is through the creation of LED lights that offer users the ability to change the direction of the light. This allows art museums to better direct light sources to minimize the amount of light that is directly hitting precious paintings. Another way museums are protecting paintings is by minimizing the amount of overhead light. Art lovers visit museums for the art, and by dimming the overall gallery, it doesn’t detract from a typical day at the museum.

LED Tunabilty Offers Additional Creativity

One of the benefits of LED lighting is the ability to play around with different varieties of lighting in a museum. Artists can use different types of LED lighting to make objects look completely different, which opens up the possibilities for the lighting itself to be a part of art exhibits around the world.

LED Testing Key to Protecting Paintings

LED testing is especially important when lights will be used to illuminate valuable paintings.  At Gooch & Housego, we offer a variety of testing equipment, such as the OL 770-LED that allow lighting manufacturers to ensure their products will meet all necessary industry standards.

IKEA to Only Sell LEDs By 2016

the-lights-231485_1280Modern furniture retailer, IKEA, recently announced that by 2016, the company plans to replace all of its traditional lighting fixtures with LED lights. IKEA claims that it will be the first US furniture retailer to move toward selling LED lighting exclusively, and points to the many environmental benefits of LEDs as the reason for the change. And what are some of the benefits of using LEDs? Spectroradiometer manufacturer, Gooch & Housego, lists some of the benefits of using LEDs over traditional incandescent light bulbs.

Costs of LED Lighting Continue to Fall

While many may look at this move as cost prohibitive for a variety of consumers, thanks to advances in LED testing and technology, LEDs are must more affordable than ever before.  IKEA contends that they will be selling LED bulbs at the lowest prices in the market (currently their lowest priced bulb starts at $9.99).

Renewed Focus on Longevity

While IKEA’s furniture is not always looked upon as long lasting, IKEA claims that its LED bulbs will last up to 20 years, which is comparable to other major manufacturers, such as Philips that sell bulbs at much higher price points.

What Does This Means for the Lighting Industry?

As large companies like IKEA make a vow to utilize LED lighting exclusively, other companies will no doubt follow to gain traction and notoriety in their markets. This is great news for energy conservationists that are focused on renewable resources. LED lighting is no doubt the future of inexpensive, yet extremely efficient lighting in all types of industries.

Gooch & Housego Commends IKEA On Their Stance on LED Lighting

At Gooch & Housego, we commend IKEA for taking a stand when it comes to LED lighting.  The reality is that if more companies were to take a similar stance, they would command much more buying power with LED manufacturers, allowing prices for LED bulbs to continue to fall. We hope that as more companies follow IKEA’s lead, we’ll see a worldwide adoption to LED lighting.

Gooch & Housego offers a variety of spectroradiometers and LED testing equipment, like the OL 770-LED, that lighting manufacturers use to ensure their lighting products meet certain regulatory standards.

That Salad You’re Eating? It May Have Been Grown by LEDs

Philips has recently opened GrowWise City, an indoor farm based in the Netherlands. This indoor experiment is meant to perform research into how our world can respond to the ever-growing demands for more food with a limited amount of usable farmland.

Details of GrowWise City Environment

GrowWise City is completely LED powered and covers a whopping 2,500 square feet of area.  Researchers are attempting to develop what they’re calling “LED light growth recipes” that allow farmers to grow crops using LED lighting for the entire year without the need for soil or sunlight.

The environment at GrowWise is completely clean and closed so that no natural light or air can enter the space. The site uses a completely customized LED system that can provide varying sequences of light based on the unique needs of different plants. This unique targeting of nutrients will allow farmers to grow produce vegetables that are fully pesticide-free and 100% organic.

The area is made up of four layers of plant racks in eight different rooms, all with differing climates. Each layer of the racks use Philips’ GreenPower LEDs, which have been specifically developed to work with growing crops. These unique LEDs are able to be customized-based on the unique needs of the plants.

Wide Array of Applications for This Type of Lighting

Currently, researchers are focused on recipes to grow herbs, strawberries, and leafy vegetables, but once these have been mastered, researchers can move towards other crops, like wheat and potatoes.

LED Testing Key to Safety

When you’re dealing with LED lighting in close proximity to a food source, it’s important that proper LED testing is conducted to ensure that the lighting fixtures are safe. At Gooch & Housego, our OL 770-LED offers lighting manufacturers an easy way to ensure that their LED fixtures are 100% safe, even when used in a facility that grows a variety of crops.

5 Bridges in NYC to Use LED Lights

New York City residents will be excited to hear that decorative LED lights are about to be installed on bridges over the Codorus Creek in New York City. County commissioners recently approved a deal that will allow a local nonprofit, Downtown Inc, to install LED lights on five county-owned bridges.

  • Benefits of LED Lighting: These new decorative LED lights will be installed on the railings of these bridges and will allow light to be cast onto the sidewalks as well as portions of the Codorus Creek.
  • Variety of Lighting Options Being Considered: There are a variety of different lighting options being considered. One option is just to use standard white LED lights, while another is to use lights that can change colors. This would allow the bridges to be lit up with various colors for different community events and holidays.  The versatility of LED lighting offers a whole host of economical and attractive lighting options for York City.
  • Lights Also Meant for Safety: At least one of the bridges will also feature a motion sensor light that will trigger the LED lights when someone is walking under the bridge.

While New York City is starting with just five bridges, they’re hoping to expand this initiative to a variety of other bridges in the city. Since this project is just in its infancy stages, it could take years to complete.

All LED Lighting Subject to Intense Testing

Before any type of LED lighting can be installed, rigorous LED testing must take place to ensure that fixtures are not emitting dangerous levels of radiation. Using LED measurement equipment, like the OL 770-LED from Gooch & Housego, companies can ensure that their lighting equipment meets certain specifications laid out by the government. For more information about the OL 770-LED, don’t hesitate to contact the Gooch & Housego sales team today at 800-899-3171.

Cathedral Shines with LEDs

The reach of LED technology is making its way to ancient cathedrals of all places. One cathedral that is utilizing the latest LED lighting technology, to not only improve the experience for visitors to the cathedral, but to also save on energy costs is the Milan cathedral in Italy. In preparation for this years long awaited EXPO 2015, the organization that manages the cathedral has been investing heavily in switching the facility over to LED lighting. LED testing expert, Gooch & Housego, explains.

Local Lighting Designers Presented With a Unique Problem

Local lighting designers Ferrara Palladino e Associati were commissioned to help convert the Milan cathedral over to LED lighting. Their task was to replace the current spotlights and lenses with an LED system that complemented the historic features of this wondrous structure, as well as to reduce the operating costs for energy usage going forward.

The old lighting system consisted of 175 flood lights each with 400w lamps that were strategically mounted at the base of the cathedral to provide a uniform illumination of the inside of the structure. While this solution was economical during its day, it has long become obsolete thanks to all of the advances in lighting technology.

Lighting designers chose LED lighting technology from ERCO, which included LED lenses that allowed new design opportunities. The old lighting system used a cool color that resembled daylight, while the new LED system uses LEDs with 4000K outputs that offer a calmer ambiance and make the ancient structure look more natural.

Significant Cost Savings With LED Lights

This project was able to cut energy usage by almost two thirds, going from 70kW to 23.7kW. This large drop in energy usage earned the project an A+ energy efficiency rating as well as an Environmental Friendly Innovation Award by Italian organization Legambiente.

Future is Bright for Historic Buildings

As was the case with the Milan LED lighting project, other historic buildings should take note of the energy savings, as well as the aesthetic improvements, that can be seen with LED lighting.

LEDs Improve Again with the Help of Nanowires

New studies in LED testing have shown that LEDs created with nanowires use smaller amounts of energy and give off improved light. Researchers examined nanowires using X-rays and were able to find precisely how the nanowire should be composed in this technique.

A nanowire is extremely small, roughly two mircometers high and ranging from 10-500 nanometers in diameter. Nanowires have an inner core made up of 2 semiconducting metals: gallium and indium-gallium-nitride. The mechanical tension between these two semiconductors forces light to be dependent in the LED and when the two come in contact with one another, the tension becomes increasingly more dependent. Scientists studied many nanowires using X-rays at the microscopic level, and although the nanowires should have been the same, they discovered the nanowires were rather unique in composition.

This development in LED testing was discovered when 20 nanowires were measured and studied. The results showed very clear and detailed images of each nanowire. The composition of the outer layer and inner core were easily visible, allowing researchers to spot any structures that were subtly bent. The structures with these issues don’t perform as well, therefore researchers can tell precisely what nanowires will perform the best and have the most efficiency in the inner core and outer layer structures. Although the process is usually time consuming, scientists were able to study many nanowires at one time through the use of a unique design of an X-ray that didn’t ruin any nanowires in the procedure.

The information from the production of these nanowires can help change the layer format in nanowires. LEDs made with these nanowires would give off light that appears more natural and use far less power. The technological uses of nanowires could also be used in other forms of lighting, like televisions and mobile devices within the next 5 years.
Knowing how LED testing is advancing and learning what new products are coming to the market in the near future is important. For any questions you may have about Gooch and Housego’s products and services, please call 407-422-3171, or contact us online.

A New Lasing Technique Creates New Grid

As a result of recent research in lasing processes by Brookhaven National Laboratory, they have discovered a new patterning technique that can create large, nanostructured grids that could improve production of solar cells, optical coatings, and touch screens. Objects at the nanoscale level only reach billionths of a meter. However, their shape and size can create strong visual effects and electronics. That’s why it has been difficult in LED testing for researchers to build bigger materials that hold faint nanoscale attributes.

By overcoming these hardships, scientists have found a way to quickly make nano-structured grids for usable materials with extraordinary adaptability. Researchers can now create multi-layer grids made of various materials in nearly any geometric shape. In rapidly and separately handling the nanoscale composition and shape, scientists can fabricate the ability of these materials. Most importantly, the technique used to make the nanoscale structures can easily be applied to bigger functions. With this new breakthrough, the outcome in having these materials on the larger scale can lead to the evolution of enhanced solar cells, optical coatings, and touchscreen devices.

The new method depends on polymer self-production, where molecules are made to randomly come together into aspired compositions. Self-production needs a burst of heat to create molecules that connect into the right formations. In a matter of seconds, polymer blocks that were in complete disarray, morphed into exact configurations when an extremely hot laser moved across it. Structures that are self-assembled often follow molecular preferences on their own. This makes creating unique structures difficult. The new method discovered by researchers in LED testing has allowed them to force these stubborn materials to come together in certain ways. The structures can be built layer-by-layer, creating frames made of multiple shapes.

The scientists at Brookhaven National Laboratory have come far in the world of LED testing. Their developments will advance technology even further and enable them to understand more about lasers and the many uses they have. Gooch & Housego also continues to produce and supply customers with many LED testing and services. Please contact us at 407-422-3171 today for any questions you may have about our business.

This LED Can be Stuck to the Wall?

New developments in LED testing have helped pave the way to OLEDs (organic light-emitting diode) sticking to a wall with the help of a magnetic mat. The OLED is removable and would be able to stick to the wall or even come off just as easily. South Korean company, LG, created an OLED TV that is so thin it measures in at 0.97 mm and is 55” in length, weighing only 4.2 pounds. Prior to this new technological phenomenon, the existing 55” OLED TV by LG was 4.3 mm thick.

During LG’s media event, they used a magnetic mat that could attach and detach from the OLED TV and placed it on a wall. Removal of the TV screen is simple because it is so thin it peels right off the magnetic mat as if it were one large sticker.

LG’s reveal shows that they may see high-end TVs as an engine for growth. Just earlier this year, LG released three different large size OLED displays and has ultimately showed how much they plan on focusing on organic LEDs. In LG’s efforts to use organic LED TVs over LED TVs, they’ve managed to create extremely thin screens with the ability to curve. Back lights will also no longer be needed in sets as organic material creates its own light. With its own light emission, OLED screens can be very thin and are being used not only for TVs, but also for mobile products.

Although there have been new developments in LED testing that tease home owners of a new TV they could stick to their wall, it’s unlikely it’ll hit the market anytime soon. The technology will most likely be used in vehicle manufacturing, commercial applications or wearable technology. There is no mistaking how far developers have come in the organic LED field, and Gooch & Housego are proud to be a part of the same industry.

Organic LED Lasers Almost a Reality Thanks to Nanostructures

A big step forward in producing organic lasers has come through the use of thinly-patterned nanostructures. Nanostructures have the ability to make bright, low-energy light sources which enables them to create organic LEDs. Researchers have used spectroradiometers to measure LEDs, but have long sought to create organic lasers. Unfortunately, carbon-based semiconductors tend to work inefficiently at the elevated currents needed to overcome overheating during lasing. This affected the production of organic LEDs until the breakthrough with nanostructures.

Lasers typically require extremely high electric currents to operate, albeit inefficiently. Such currents are not practical for regular displays and lighting. This makes using lasers in such applications very difficult. Dr. Thuc-Quyen Nguyen, a professor at the University of California, Santa Barbara, and her team gathered together with other researchers from Japan to solve the problem that high electric currents were causing during lasing. Their work with nanostructures helped them find a way toward creating organic lasers.

In using electron-beam lithography, the efficiency roll-off problem could be answered. The remedy was using electron-beam lithography to create thinly-patterned OLED structures. The small object area kept 100 times higher brightness coherence than prior recordings. The largest result in repressing efficiency roll-off was seeing an increase in efficiency at high luminescence. The outcome was achieving the same luminescence with lower power.

With advances in organic LEDs through the uses of nanostructures, researchers will be able to expand on the field even further. New developments are being discovered as technology continues to improve. In the meantime, you may be interested in finding a way to easily quantify your OLED laser efficiency.
