The Future is Bright with OLEDs (Organic LEDs)

- - Lighting News

We at Alcon Lighting have taken a particular liking to the next revolution in lighting technology. “Researching for the next stage of LEDs, we stumbled upon Organic LEDs, a lighting technology that is being advocated as an architectural lighting game-changer,” says Jake Hakimi, director of Sales for Alcon Lighting. That technology is the organic light-emitting diode (OLED). OLEDs are solid-state devices composed of thin films of organic molecules that create light with the application of electricity. OLEDs provide brighter, sharper displays for on various electronic devices, and consume less power than traditional LEDs or LCDs.

The OLEDs are millimeters thin and have the ability to emit the whole color spectrum. With recent advances, it is looking like OLEDs have the potential to move beyond consumer electronics and displays, and into architecture and lighting. Because of their small width, flexibility and transparent components, OLEDs have the latent ability to act as walls or windows that can transform into light sources. “Instead of the environment having to accept the lighting, the lighting fits into the environment,” states Barry Young, managing director of the OLED association. OLED can prospectively change how light and architecture will be experienced. Alcon Lighting, has decided to put OLEDs on display at their Los Angeles showroom. “We strive to keep current with the latest trends in energy efficient lighting and we’ve decided to put OLEDs on display to show our customers what’s coming up in the industry,” says David Hakimi, Co-Director of sales at Alcon Lighting.

Compared to a standard LED (with which light is emitted from a single point), OLED light is diffused over its surface area. A typical OLED is composed of an emissive layer, a conductive layer, a substrate, and both anode and cathode terminals. The layers are made of organic molecules that conduct electricity. These layers of organic semiconductor material are formed between two electrodes. Generally, at least one of these electrodes is transparent. The layers have conductivity levels ranging from insulators to conductors, so OLEDs are considered organic semiconductors. When voltage is is applied, these layers conduct the electricity and begin to glow.

In terms of energy efficiency, current OLEDs have an energy output of approximately 25 lumens per watt – compared to an average of 17 lumens per watt of traditional incandescent lights. OLEDs offer many advantages over both LCDS and LEDs. Compared to the crystalline layers in an LED or LCD – the plastic, organic layers of an OLED are thinner, lighter and more flexible. Being that the OLED substrates are made of plastic, they can be more pliable and less rigid than the glass used by LEDs and LCDS. OLEDs have the ability to generate light themselves, and because they do not require backlighting they consume much less power than your typical LCD. Also, unlike LCDs which work by blocking light, the self-produced light of OLEDs offers a much wider viewing range. Production-wise, OLEDs are easier to manufacture and because of their plastic-based materials they can be made to larger sizes.

OLED’s architectural application includes use in various light housings and sources for general space illumination, as well as large-area light-emitting elements. Compared to inorganic solid-state LEDs (designed for point-light applications and sources), OLEDs characteristically emit less light per unit area – making them preferable where copious amounts of light are desired. Future developments of OLED will see higher, more compatible outlets, so that they will be able to compete as sustainable products. OLED Association’s Young also noted (and Cornell research has reaffirmed), “There is even hope that the technology can be used as a power source. OLEDs opterate by converting electrical energy into light, but if you think about reversing that, you can convert light to energy.

Alcon Lighting Embraces LED Landscape Lighting

With green technology becoming more important and prevalent, LED lighting stands at the forefront of this eco-movement. Alcon Lighting, a Los Angeles-based lighting and electric supply company has fully embraced LED lighting and they are rapidly revolutionizing the lighting and electric supply industry. LED lights are energy efficient, low voltage, low amperage, and low wattage – providing ultra bright light that generates virtually no heat compared to halogen, incandescent or compact fluorescent lighting. In terms of their usability benefits, LEDs can be catered to provide illumination in almost any kind of application. The distinct characteristics of LEDs allow for easy adaptation to new forms of lighting; new form factors, and cutting-edge bulb types that outperform existing bulb sources.

According to David Hakimi, Co-Director of Sales at Alcon Lighting, “Humans by nature are phototropic beings (attracted to light), and proper lighting has the ability to appeal strongly to our senses and emotions. The emotional power that emanates creates atmosphere and enriches life.” In the realm of home improvement – landscape lighting is becoming a commanding new trend. Landscape LED lighting has the potential to take over that market and illuminate a wide variety of landscapes. More than ever before, homeowners are looking to upgrade their property’s aesthetics and with proper landscape lighting they will have great opportunity to make a stunning first impression.

Alcon Lighting has earned great prestige for its integration of the highest quality landscape lighting amongst a wide variety of environments. Alcon’s LED specialist, David Hakimi stated that, “our extensive array of LED directional lighting fixtures, LED pathway fixtures, & LED well lighting fixtures have led to a substantial growth of our company in the landscape lighting market. In terms of cost savings, LED light bulbs afford the consumer reduced energy usage in addition to savings on replacement costs (as compared to traditional bulbs). With LEDs as opposed to fluorescents, consumers are able to switch to energy efficient and environmentally friendly lighting solutions without losing light quality.”

In most home applications, LED bulbs are expected to pay for themselves in less two years from energy and replacement savings alone and now most LED manufacturers offer a minimum 3-year warranty. The Holiday Inn chain of hotels recently switched over to energy efficient LED lighting for their signage, which will lead to an estimated $4.4 million in savings annually. According to the Director of Sustainability for The Holiday Inn, “Switching from neon and florescent to LED breaks down to $3 million in savings on annual maintenance, and $1.4 million on energy savings.”

In the United States, lighting accounts for about 11 percent of all residential energy use and 26 percent of all commercial energy use. Life cycle assessments of LED lights have revealed that LED lamps are competitive to compact fluorescent lamps today (while not containing harmful elements such as lead or mercury), and future technological developments will only further cut down on energy demand. In terms of LED lamp production, less than 2 percent of total energy demand is needed to create them. Alcon Lighting has provided consultation in several LED analysis and application specified projects.

To highlight the growth, savings, and application of LED lighting: In 2009, Los Angeles Mayor Antonio Villaraigosa, with former-President Bill Clinton by his side, announced a new streetlight program to retrofit all of the city’s streetlight fixtures with energy and cost saving LED fixtures. Once the project is finished and the debt is retired, the city will save over $10 million annually, while simultaneously cutting energy usage by 40 percent and reducing carbon emissions by more than 40,000 tons a year.

Alcon’s LED lighting selection is a great new resource for designers, contractors, and consumers who want to save energy and create exciting lighting design. “LED technology allows for paramount reliability, flexibility and performance. And we’re just taking advantage of it.” remarked Jake Hakimi, Co-Director of Sales at Alcon Lighting.
