Current market-ready or near market-ready uses of LED lighting include:

Commercial Signage: Commercial signage often operates 12 to 24 hours per day, consuming about 2% of the total electricity in the United States. Fluorescent signs currently account for about 48% of this market, with neon signs holding about 41%, and the remainder of the market dominated by incandescent products.

Institutional, Industrial and Commercial Lighting: LED products can have a significant impact on energy use in airport, ports and roadway lighting, where conventional fluorescent- and incandescent-lit signage is heavily used.

Retail Lighting: LEDs offer unprecedented flexibility in colors and configurations to lighting designers in creating displays and “moods” in retail settings.

Key resources pertaining to LED technology:

• LED Lighting Systems, 2003 (47 pgs.), by John Bullough
• Information from ENERGY STAR about high efficiency exit signs and traffic signals
• Information from the Lighting Research Center at Rensselaer Polytechnic Institute on LEDs in transportation applications and exit signs
• Specifications on LED traffic signals developed by the California Department of Transportation (Caltrans)

LEDs are rapidly rippling across the transportation and vehicle applciations because of their long life, energy efficiency, standalone solar power capability...and brightness.  Here are some recent trends in LED applications:

LED Indicators and signs

Status indicators on a variety of equipment are used which include traffic lights and signals, Exit signs, Railroad crossing signals, Continuity indicators and Elevator push-button Lighting .

Thin, lightweight message displays at airports and railway stations, and as destination displays for trains, buses, trams, and ferries.

Red or yellow LEDs are used in indicator and alphanumeric displays in environments where night vision must be retained: aircraft cockpits, submarine and ship bridges, astronomy observatories, and in the field, e.g. night time animal watching and military field use.

Red, yellow, green, and blue LEDs can be used for model railroading applications

In dot matrix arrangements for displaying messages.

Because of their long life and fast switching times, LEDs have been used for automotive high-mounted brake lights and truck and bus brake lights and turn signals for some time, but many high-end vehicles are now starting to use LEDs for their entire rear light clusters.

Besides the gain in reliability, this has styling advantages because LEDs are capable of forming much thinner lights than incandescent lamps with parabolic reflectors.

The significant improvement in the time taken to light up (perhaps 0.5s faster than an incandescent bulb) improves safety by giving drivers more time to react. It has been reported that at normal highway speeds this equals one car length increased reaction time for the car behind. White LED headlamps are beginning to make an appearance.

As a medium quality voltage reference in electronic circuits. The forward voltage drop (e.g., about 1.7 V for a normal red LED) can be used instead of a Zener Diode low-voltage regulators. Although LED forward voltage is much more current-dependent than a good Zener, Zener diodes are not available below voltages of about 3 V.

XLamp® LED was selected as the light source for a new lantern from MUJI of Japan. Cree’s XLamp LEDs were selected for their market leading performance.

MUJI assigned the lantern project to G-Com Co., Ltd., a Japanese-based original equipment manufacturer. The sleek MUJI lanterns can be used as table lights or portable torches. G-Com’s product design required a bright light source that generates very little heat. The complete lantern design also had to create an aesthetically pleasing product for MUJI’s high-end customer base. Cree’s XLamp LEDs were the natural choice to fulfill the requirements.

“We first chose Cree XLamp XR-E LEDs for MUJI’s high-power bicycle lights, and then again for the new lanterns. It is important to provide the best products for major brands such as MUJI,” said Tohru Chigusa, G-COM vice president. “We found that Cree XLamp LEDs offer the best brightness and lowest heat emission for packaged LEDs, and Cree’s sales and support people added great value to the product design process.”

For additional information on the benefits of converting various lighting applications to LED lighting in the work environment and to learn more about LED Workplace, visit www.ledworkplace.org.

Cree is using its headquarters facilities as a testbed for LED implementation. 

They are converting all lighting at its Durham headquarters and manufacturing facility to LED lighting and released the results of the first phase of the conversion. The parking lots, entryways, lobby and conference rooms at Cree's headquarters building are now 100-percent lit by energy-efficient, environmentally friendly XLamp(R) LEDs.

Cree's LED Workplace(TM) conversion validates the energy savings, quality of light and reality that LED lighting is now a viable option for business and residential consumers.

In a study of the energy usage before and after the lighting conversion, Cree confirmed the energy savings of the newly installed LED lights.

The findings indicate that in total the new LED lights use 48% less energy than the incandescent, fluorescent and high-pressure sodium lights they replaced.

The combination of the energy savings, reduced maintenance and disposal costs and the environmental savings demonstrate that LED lighting is now a real alternative to traditional lighting solutions.

Duke Energy Collaboration

Cree's local utility, Duke Energy, is collaborating with Cree to explore the benefits of LED lighting. "Our customers are always interested in understanding how to save money through energy efficiency, so we make it our business to support innovative technologies such as LEDs," said Ted Schultz, Duke's vice president of energy efficiency.

"We expect our energy efficiency plans to be approved next year (2008) and are committed to having a complete line of lighting solutions available for customers," said Schultz. "At that point, we expect to have programs developed that will take advantage of LED technology."

"Conventional wisdom is that LED lighting is years away from widespread adoption. The truth, however, is that the performance of Cree's LED technology enables real LED lighting solutions today," said Chuck Swoboda, Cree chairman and CEO. "The conversion of Cree's site demonstrates that the LED Lighting Revolution is well underway and will illustrate the benefits in energy savings, maintenance costs and environmental impacts."

Cree also announced that it has launched a new website to share the results and implementation details of the LED Workplace lighting conversion with other organizations.
 
...will include lighting vendor information and the light, energy and maintenance metrics that form the basis for LED lighting's cost savings. This site will also feature other LED Workplace installations.

A new version of Cree's LR6 dowlight, designed for 220V to 240V electrical systems, has been released to address Europe, Asia, and other major markets.

LR6 Delivers Energy-Efficient and Environmentally Safe Lighting

Solar Cynergy's theme is "Bringing Japanese innovation to the lighting industry."

John Huang, Corona, CA based sales and marketing manager explains that Solar Cynergy has married the sustainable contributions of Japan and the US. "As a Berkeley alum, I'm extremely interested in sustainable design and products and am hoping to educate the general public on the strides and advances in solar lighting technology."

Solar Cynergy introduced a family of solar LED lighting technology for residential, commercial and city applications in May at the 2007 Lightfair International Trade Show & Conference. One patented advantage offered by Solar Cynergy is that the solar collection panels are removed from view.

Solar Cynergy is a unique solar LED light utilizing patent protected condenser technology in place of traditional batteries to provide the user with brighter and more colorful illuminations with an industrial strength stand alone unit. Off-grid. Affordable cost. Long life. "Solar LED lighting has really improved in the past few years," he notes," pricing is continuing to fall, more colors are available, and the quality has improved so that new products can last as long as 25 years."

Solar Cynergy on-ground lights are strong enough to withstand even a tank driving over it!

Application & Use of Solar LED Lights

From enhancing the decor of a backyard and illuminating walkways to providing hazard and safety lighting to parks, schools, dangerous intersections or crosswalks, Solar Cynergy offers facilities and communities an eco-friendly and cost-effective alternative to conventional wired lighting.

Embedded into the ground, each solar LED unit is self contained, free from complicated wiring, and provides a colorful luminescent glow that is resistant to the elements, charges even on cloudy days, and industrial models can provide 15 hours of output (residential models: 8-10 hours) on an average 8-12 hour charge. That's two nights of light for a typical day's charge.

Innovative Design of Solar LED Environmental Lighting

• The Solar Cynergy RSC series is made of a polycarbonate resin and utilizes two double layered condensers, allowing for explicit illumination and eliminating the hassle of switching batteries.
• Using solar energy, the light automatically charges during the day (on 12,000 lumens -- about equal to a cloudy day or a hazy late afternoon -- and automatically turns on as the sun sets.
• Lighting choices are available in blue, green, white, halogen white and red.
• 10 MW LEDs provide non-invasive lighting with a glow that isn't strong enough to contribute to light pollution of the night skies.
• For more industrial applications, the CSL series offers cities with high grade flashing solutions that are ideal as hazard or safety precautions on streets, or along sidewalks.

Sourcing Solar LED Lights

All Solar Cynergy products are manufactured in Japan. When asked about the cost-effectiveness and environmental aspects of manufacturing these LED lights in Japan, John Huang at Solar Cynergy in Cornoa, CA, replied, "while we do manufacture overseas in Japan (for technology and efficiency reasons), we ship units over in large quantities by sea and keep inventories in our Corona warehouse. Unfortunately, there is a tremendous amount of technology within each unit and manufacturing in the US would drive up cost and make our technology less accessible to consumers."

Solar Cynergy concentrates on cost-effective advances in solar technology and is rooted both in the United States and Japan. Solar Cynergy fuses design and innovation with conservation and sustainability. "Our line of solar LED models has a lifetime expectancy of 25+ years which we stand by with a 10 year manufacturer's warranty. Avoiding the cost of running conduit or wires and the added flexibility of placing accent lighting away from any grids, we feel you would break even within the year. However it depends on a case by case analysis depending on how much current exterior/accent lighting you currently use, etc.

"We work with a number of professional installers that we outsource business to," says Huang. Two of the California sources for leading-edge lighting sources to comply with LEED and California Preferable Products are Southern California Illumination (Los Angeles) and O'Connor Sales (San Diego).

October  2006 — LEDtronics® introduced the  S6 Right-Angle Candelabra LED Bulbs that  light up many different types of applications.

These LED bulbs fit almost any S6 screw base application with a right-angle mounting fixture-to-lens setup that is great for many applications such as lighting stadium seating, theatre stair pathways, aisles, and accent night lighting.

These high quality LED bulbs produce very little heat, thus reducing the risk of fire hazards. Furthermore, these great S6 LED bulbs only consume 0.935 watts of power compared to the usual 4 or 7 watts for incandescent used in these applications!

These right angle LED bulbs come in cool and warm white in both normal and super bright applications for your 120V AC outputs. The normal LED gives off 3 and 2 lumens for cool and warm white colors, while the super bright cool and warm color LED outputs 5 and 3.8 lumens, respectively. The S6 cool white uses 8000K LEDs and puts out 13,000 MCD at 17° angles or a warm white 3000K LED that puts out 14,000 MCD at 20° angles.

Solid-state design renders LEDs impervious to shock, vibration, frequent switching, and environmental extremes. With an average life span of 100,000-plus hours (11 years), LED lamps operate more than 20 to 30 times longer than the equivalent incandescent lamp! Savings from reduced maintenance costs and downtime quickly return the capital investment expenditure! LED lamps produce almost no heat and require 80% - 90% less operating power than equivalent incandescents, making them as friendly to the environment as they are to the operating budget.
