Interesting Info
Lounge Lights were developed in Germany in late 2003 by artist, visionary, producer, Archim Perleberg, who just prior had produced one of the largest light shows ever seen - three major world events in Beijing, China, Budapest, Hungary and Berlin, with monumental light amazed millions of viewers with hundreds of miles of brilliantly lit landscape. Soon thereafter, he decided to take these experiences to a new level – he wanted to take this affinity and fascination he had for light and put it into a realm that we could all enjoy on a smaller scale and at a more intimate level. This idea resulted in the “Lounge Light” concept. Designed with the same inspiration and vision as his phenomenal light shows, the “Lounge Light” line stands out in the LED industry.
The Lounge Light Candle can be used without the use of flame – as a glowing decoration, standing, strikingly on its own merits. It can be used for a particular theme -- a beautiful candle with a warm, bright flame set to the surrounding colour scheme or décor, or it may be used as an entertaining light event in itself, with a constantly changing interplay between the warmth of the candlelight and the glow from within.
Our Light Engine
All Lounge Light products are powered by a State-of-the-Art proprietary 4.5 volt battery designed to last at least 100 hrs so you can enjoy your Lounge Light products.
The Battery:
There was no battery on the market that met the Lounge Light vision or standard of battery duration, so we created our own to guarantee your Lounge Light product long life. The result is a battery that gives over 100 hours of service, and is environmentally safe, as it contains no mercury or cadmium. It is based on alkaline technology, the same kind used with batteries for sensitive electronic applications.
The LED:
LED stands for Light Emitting Diode, which basically means, glowing light body. Even though they have been around since the Sixties, until recently they lacked adequate intensity of light and were too expensive
to compete with cheap electric bulbs. LEDs use much less energy than conventional electrical lighting and they
generate almost no heat. The past decade has seen a revolution in LED technology. Today they are hundreds of times brighter, last up to 100,000 hours and are available in almost any colour.
A Short History of the LED
The phenomenon of electroluminescence was first observed in a piece of Silicon Carbide (SiC), in 1907 by Henry Joseph Round. The yellow light emitted by it was too dim to be of practical use and difficulties in working with Silicon Carbide meant that research was abandoned. Further experiments were carried out in Germany in the late 1920s by Bernhard Gudden and Robert Wichard Pohl, using phosphor materials made from Zinc Sulphide doped with Copper (ZnS:Cu), although once again, the low level of light produced meant that no in depth research was carried out. In 1936 George Destriau published a report on the emission of light by Zinc Sulphide (ZnS) powders, following the application of an electric current and is widely credited with having invented the term "electroluminescence".
British experiments into electroluminescence, using the semiconductor Gallium Arsenide (GaAs) in the 1950s led to the first "modern" Light Emitting Diode (LED), which appeared in the early 1960s. It is said that early experimental laboratory LEDs needed to sit in liquid nitrogen while operating and considerable effort was required to make the breakthroughs needed to create devices that would function efficiently at room temperature. The first commercial LEDs were only able to produce invisible, infra red light, but still quickly found their way into sensing and photo-electric applications.
The first visible (red) light LEDs were produced in the late 1960s, using Gallium Arsenide Phosphide (GaAsP) on a GaAs substrate. Changing to a Gallium Phosphide (GaP) substrate led to an increase in efficiency, making for brighter red LEDs and allowing the colour orange to be produced.
By the mid 1970's Gallium Phosphide (GaP) was itself being used as the light emitter and was soon producing a pale green light. LEDs using dual GaP chips (one in red and one in green) were able to emit yellow light. Yellow LEDs were also made in Russia using Silicon Carbide at around this time, although they were very inefficient compared to their Western counterparts, which were producing purer green light by the end of the decade.
The use of Gallium Aluminium Arsenide Phosphide (GaAlAsP) LEDs in the early to mid 1980s brought the first generation of superbright LEDs, first in red, then yellow and finally green. By the early 1990's ultrabright LEDs using Indium Gallium Aluminium Phosphide (InGaAlP) to produce orange-red, orange, yellow and green light had become available.
The first significant blue LEDs also appeared at the start of the 1990's, once again using Silicon Carbide - a throwback to the earliest semiconductor light sources, although like their yellow Russian ancestors the light output was very dim by today's standards. Ultrabright blue Gallium Nitride (GaN) LEDs arrived in the mid 1990s, with Indium Gallium Nitride (InGaN) LEDs producing high-intensity green and blue shortly thereafter.
The ultra bright blue chips became the basis of white LEDs, in which the light emitting chip is coated with fluorescent phosphors. These phosphors absorb the blue light from the chip and then re-emit it as white light. This same technique has been used to produce virtually any colour of visible light and today there are LEDs on the market which can produce previously "exotic" colours, such as aqua and pink.
Scientifically minded readers may have realised by now that the history of LEDs has been a long, slow "crawl up the spectrum", starting with infra-red. Indeed, the most recently developed LEDs emit not just pure violet, but genuine ultra-violet "black" light. How much further up the spectrum LEDs can "go" is a matter of speculation, but who knows ? it may one day even be possible to produce LEDs which emit X-rays.
However, the story of LEDs has not just been about colour, but brightness too. Like computers, LEDs are following their own kind of "Moore's Law", becoming roughly twice as powerful (bright) around every eighteen months. Early LEDs were only bright enough to be used as indicators, or in the displays of early calculators and digital watches. More recently they have been starting to appear in higher brightness applications and will continue to do so for some time to come. For instance: all American traffic signals will have been replaced with LEDs by late 2005; the automotive industry has sworn to banish all incandescent bulbs from cars by the end of the decade, replacing them with LEDs - even in headlights. Most of the large video screens seen at outdoor events use many thousands of LEDs to produce video pictures. Very soon, LEDs will be bright enough to light our homes, offices and even our streets as well. The extreme energy efficiency of LEDs means that solar charged batteries can power LED units by night, bringing light to the Third World and other areas with no mains electricity.
The once humble Light Emitting Diode has truly come of age and is now making the jump from mere indicator to
true ILLUMINATOR !
