FAQ

What is LECD?

LECD stands for Light Emitting Ceramic Device and is a patented solid-state luminance light used in many applications. It emits an agreeable, non-dazzling light ideal for signage, instrumentation backlighting, courtesy lighting, and architectural projects. Its key advantages are durability, energy efficiency, simplicity of operation and installation, and adaptability to any environment.

How long will LECD lights last?

LECD lamps are virtually maintenance-free and will last to up to 50,000 hours in continuous operation at 110 VAC 60 Hz. After 50,000 hours, the lamp will start fading, but will not shut off like conventional bulbs, giving operators plenty of time to plan for a replacement. Refer to our Technical Specifications for more information.

Where are LECD lights being used nowadays?

Since 2006, Ecer Technologies has been supplying LECD lights to the US Navy, US Army, Federal Aviation Administration, West Virginia State Parks, and third-party manufacturers of consumer products. In May 2013, Ecer Technologies was awarded a contract to supply LECD lights to the world's most advanced nuclear aircraft carrier, the USS Gerald Ford (to enter operation in 2016).

Is LECD really a "cold light"?

Yes. LECD does not generate any heat because it consumes very little energy. If left on for a full year, you will not notice any temperature increase on the surface of the panel. This is why the Navy has chosen this technology to maintain the balance of energy consumption and heat generation inside ships and submarines.

Why LECD consumes so little?

LECD produces a non-dazzling light that humans can see without being disturbed. Contrary to other source lights, the fluorescent light emitted by the LECD is highly perceptible by the human eye and is not strong enough to cause light dispersion and discomfort. Yet, it is extremely centered and vivid. Therefore, it can be beamed directly using almost the totality of its outputted light.

Can LECD lights be powered with solar energy?

Yes. LECD lights consume less than 0.002 Watt/sq.in. and can be powered using rechargeable batteries widely available in the market. Solar panels will, in turn, recharge the batteries during daylight conditions. This setup is ideal to avoid expensive electrical cabling.

Is LECD the same as electro-luminescent (EL)?

LECD is a form of EL but it is very different from other EL devices found in the market, including plastic-EL and Light Emitting Capacitor (LEC).

LECD is made of steel and ceramics, and is intended for durable, heavy-duty use in commercial, residential, and military applications. Contrary to plastic, ceramic is 100% permeable and protects phosphors from oxygen contamination, making them last up to 10 times more than in any other device. Also, LECD consumes very little energy, does not generate heat, works directly with 120 VAC, and resists to high-temperature environments.

Does LECD need special power supplies or ballasts?

Not necessarily. LECD panels were designed to work directly with 120 VAC 60 Hz without using inverters or transformers (direct feed with surge protection). However, other colors and luminance can be achieved by varying the input voltage and frequency, which in this case an inverter, transformer, or driver is needed.

At this point, for countries whose electrical supply is 220/240V, an AC-to-AC transformer must be used to lower the voltage. Nevertheless, a higher voltage LECD device is currently being developed. Also, since LECD lamps drain very little current, they can be fed using batteries, in which case a DC-to-AC inverter would be needed.

How resistant are LECD panels?

LECD panels are made of steal and ceramics, both of which resist to significant pressure forces. However, ceramic does not resist to traction. This is why glass breaks when bended. But since the LECD ceramic layers are so thin and rest on top of steel, they require a hammer to break them. Tests performed in-house have shown an LECD panel still lighting up after being perforated and submitted to shocks of up to 1,500 lb.

Do I need to encapsulate LECD panels?

It is not mandatory to do so for indoor use. However, you do need to isolate the rear chassis, since the latter is made of steal and conducts electricity. A simple laminated layer can isolate the panel to avoid the risk of electric shocks. If the panel is going to suffer physical abuse, such as when placed on stairs to illuminate a pathway, then mechanical protection is recommended (e.g., acrylic or polycarbonate encapsulation). For outdoor applications, LECD panels need to be cased to protect them against moisture. Check the OEM Procedures Manual for a list of recommended encapsulation methods and detailed handling information.

Can I use LECD lamps for eco/green products and LEED projects?

You certainly can - and should. LECD lamps consume so little power that your energy budget will benefit from using this energy-efficient technology in exterior and interior signage. As an example, a 50 sq.in. panel in continuous operation during one year will consume less than 2 kWatts, the equivalent of $0.26 as of April 2013. No other electrical sign can achieve such energy savings. Refer to our Case Studies for more information.

What colors are available?

At 110VAC 60 Hz, LECD generates a green color at approximately 550 nm (fluorescent green). The color spectrum increases in bandwidth up to paint to the surface of the panel. Refer to the Photometric Measurements for more information.

Who else manufactures LECD lights?

To date, Ecer Technologies is the sole manufacturer of LECD lights. The technology is protected by several patents and is the result of more than ten years of research and collaboration with reputational institutions such as the US Department of Energy, The NY State School of Ceramics at Alfred University, and Marshall University.
