Natural Full Spectrum Light Boosts Health and Led’s Will Boost Communications
Denny Langston asked:
In recent years research scientists have been taking a closer look at the lighting in our homes, offices and vehicles. They are seeing potential for ways of improving health and finding new means of electronic communication through LED’s and natural full spectrum lighting.
Though this will not happen tomorrow, experts at the Rensselaer Polytechnic Institute in Troy, N.Y., an academic home for lighting research, are confident that this burgeoning field of study will soon reap outstanding rewards.
According to lighting engineer, E. Fred Schubert, a new era of “smart” light sources is just beginning. “We are looking at lighting systems that provide more than lighting,” says Shubert. Shubert is talking about light-emitting diodes, or LED’s. Most people know them as being quite small, like the lights that form numbers on digital clocks or blink on answering machines; however recent technological advances have increased their luminosity significantly. These increases have made it possible for LED’s to illuminate swimming pools and serve as traffic signals, and with time these low-cost light sources will perform even more tasks.
Though LED’s offer energy savings when compared to standard lighting, Schubert and other researchers are more excited about the communications that they may provide. The latter is because LED’s can be made to blink so fast that a person doesn’t notice, but a receiving device can. And that, Schubert says, opens the door to using lights for electronic communication as well as illumination.
Of course, fiber optic cables already transmit lots of data with light signals. But Schubert is talking about things like:
Brake lights that tell a closely following car to stop Headlights that tell a red stop light to turn green Road signs that communicate warnings to specific cars. Room lights that link your computer to the Internet, avoiding Wi-Fi signals that can be pirated.
Schubert said such uses depend on overcoming some basic technical barriers, like making them more powerful and energy-efficient. He states, “I think we’re looking at maybe a timeframe of the next five to twenty years.”
Meanwhile, Mariana Figueiro, program director at Rensselaer’s Lighting Research Center and head of a committee on light and human health for the Illuminating Engineering Society of North America, believes that lighting in offices and schools could be improved to help people stay healthy and productive, by acting on their internal body clocks. “Light isn’t just for vision anymore,” says Figueiro, “Light cues, especially blue light, help keep the 24-hr biological clock on its daily cycle.” Figueiro indicated that studies suggest such possibilities as seasonal depression, fatigue, and sleep disturbances; and have even gone so far as suggest that maybe even cancer, especially breast cancer could be influenced by the lighting used in buildings.
Be on the lookout for more breaking news related to the use of LED’s and natural full spectrum lighting being used in buildings.

New Concept of Green & Energy-saving Lighting – LED Light
ELECOSN asked:
LEDs are solid-state semiconductor devices that convert electrical energy directly into light.
Thermal sources of light such as flames and incandescent filaments emit light when heated, either by chemical reaction (flames) or electrical heating (filament lamps). LED “cold” generation of light leads to high efficacy because most of the energy radiates within the visible spectrum.
Other common high efficiency light sources, such as fluorescent lamps and electro luminescent devices, also produce light without much thermal radiation outside the visible spectrum.
Because LEDs are solid-state devices, they can be extremely small and durable; they also provide longer lamp life than other sources.
Light is generated inside the chip, a solid crystal material, when current flows across the junctions of different material compositions.
An LED consists of two elements of processed material called P-type semiconductors and N-type semiconductors. These two elements are placed in direct contact, forming a region called the P-N junction. The composition of the different materials determines the wavelength and therefore the colour of light generated.
LED resembles most other diode types, but there are important differences. The LED has a transparent package, allowing visible or IR energy to pass through. Also, the LED has a large PN-junction area whose shape is tailored to the application. The device shown in Figure 1 is an AlGaInP LED because the semiconductor layers are aluminum (Al), gallium (Ga), indium (In), and phosphate (P).
Main LED materials
The main semiconductor materials used to manufacture LEDs are:
*Indium gallium nitride (InGaN): blue, green and ultraviolet high-brightness LEDs
*Aluminum gallium indium phosphide (AlGaInP): yellow, orange and red high-brightness LEDs
*Aluminum gallium arsenide (AlGaAs): red and infrared LEDs
*Gallium phosphide (GaP): yellow and green LEDs
Why LEDs?
LEDs have a range of benefits which is fast making them the best solution for real energy efficient lighting. Over the course of the next few years some aspects are expected to change significantly.
Lifetime
As solid-state light sources, LEDs have a very long lifetime and are generally very robust due to no mechanical or moving parts.
Incandescent bulbs have an expected lifetime of 1k to 5k hours, while good quality LEDs are often quoted of having a lifetime of 50k hours, more than 5 years continuous use. However it is important to to understand that the performance of LEDs degrades over time, and this degradation is strongly affected by factors such as operating current and temperature.
Low maintenance
The long lifetime of LEDs reduces the need to replace failed lamps, and this can lead to significant financial and environmental savings, particularly in maintenance, labour and recycling. This makes LED fixtures useful for installations in inaccessible locations, but if tasks like cleaning the light fixture are required, then the light sources could be replaced at the same time, negating the “low maintenance” advantage.
Efficiency
As a semiconductor device, LEDs are highly efficient. Current device technology is allowing the performance of these to be pushed to limits that exceed that of standard lighting.
The directional nature of light produced by LEDs allows the design of luminaires with higher overall efficiency.
Low power consumption
The low power consumption of LEDs leads to large energy savings that can often drive the installation of LED-based systems. Initial purchase costs start off higher, but can be proven to return the investment cost in a short period of time.
Brightness
Light outputs are constantly being increased and there are several products that have higher lumen output than traditional lighting.
Heat
LEDs do not produce heat in the form of infrared radiation (IR) unlike incandescent bulbs which makes them hot to the touch.
This lack of heat production allows LED fixtures to be used in locations where heating from conventional sources would cause a particular problem e.g. illuminating food, textiles, artifacts, etc.
However, LEDs do produce heat at the semiconductor junction within the device and good thermal management must be employed on high power devices to maintain operation life
Cost
In many applications, LEDs are expensive compared with other light sources, when measured by metrics such as “£-per-lumen”.
LED manufacturers continue to work towards reducing their production costs while at the same time increasing the light output of their devices.
However, the high initial cost of LED-based systems is offset by lower energy consumption, lower maintenance costs and other factors.
The initial cost may seem high, but take into account the electricity usage that is saved, they pay for themselves.

10W LED Bulbs Vs 75W halogen bulb running cost comparison
Small form-factors
LEDs are very small – typical high-brightness LED chips measure 0.3 mm by 0.3 mm, while high-power devices can be 1 mm x 1 mm or larger. There are many examples where the availability of small, high-brightness devices have enabled significant market advancement. The obvious example is in mobile phone handsets, where blue, green and white LEDs are now used in most models to back light keypads and liquid-crystal display (LCD) screens.
Instantaneous switch-on
LEDs switch on rapidly, even when cold, and this is a particular advantage for certain applications such as vehicle brake lights.
Colour
LEDs are available in a broad range of brilliant, saturated colours (although performance varies across the spectrum), and white devices are also available. Modules containing different colored LEDs (typically red, green and blue, or RGB) can be tuned to a huge range of colours, and easily dimmed. RGB modules provide a much wider gamut of colours than white LEDs or other traditional white light sources, which is a particular advantage in applications such as backlighting liquid-crystal displays (LCD’s).
RGB LEDs and colour mixing
LED characteristics change with time, temperature and current, and from device to device. For RGB LEDs, the performance of different colored devices changes at different rates. This can result in variation of lamp colour and intensity, and poor reproducibility.

LED Lighting Types
Now the LED bulbs are widely applied in household, office, street, shop, park etc for decoration and lightings LED lighting family mainly includes:
1. LED ball lamp
2. LED spot lamp
3. LED ground lamp
4. LED tube light
5. LED rope lamp
6. LED pool lamp
7. LED curtain lamp
8. LED Christmas (festival) lamp

Money Saving Uses of LED Lights
Jonathan Gal asked:
Do you own any LED lights? Chances are you may have more of these highly efficient little light bulbs than you are even aware of. They show up as indicator lights in computer and electronic equipment, appear in flashlights and remote controls, exterior lighting fixtures and even holiday light strands. They are remarkably efficient and durable, which makes them suitable to a significantly wider range of applications than traditional light bulbs. A perfect such solution is obvious in gardening and the use of solar path lighting.
What are LED lights? A simple definition is actually not that easy to provide in brief, but basically LED stands for “light emitting diode” which are small electronic units that light up when electricity passes through them. Traditional light bulbs are radically different from LEDs, as they use a filament inside of the bulb which lights up when an electrical current is completed. Such light bulbs burn out rapidly and generate quite a bit of heat – in fact touching a lit bulb can lead to a burn. LEDs however stay relatively cool to the touch because they do not operate in the same manner, and are actually more like an old-fashioned transistor than a light bulb. What this means is that they use electricity far more affectively than their old-fashioned counter parts, and are far less likely to fail.
What are the benefits of LED lights? Their main benefit is their remarkable efficiency. While they may cost more at the initial point of purchase, LED lights will last for a very long time. They are resistant to blows, dropping and shock, they are relatively unaffected by continual dimming or turning on and off, they are much smaller and provide a wide range of uses. Additionally, they can appear in many colors through a manipulation of their diode and semiconductor materials, which eliminates the needs for special filters or color applications, which in turn greatly reduces the overall cost of the lighting fixtures in which they appear. Additionally, they do not contain the toxic elements and components of other lighting options, including such heavy metals as mercury which frequently appears in fluorescent lights.
How are LEDs used every day? If you take a quick car trip you will see exactly how LEDs are used in “every day” applications – they are in street lights, automobile signals and tail lights, billboards and signs, solar yard lights, exterior lighting such as spotlights on flag poles or strings of Christmas lights, and you may even notice them on security cameras where they are used for night vision purposes.
Clearly LED lights are all around, and their efficiency and ever decreasing costs will continue to make them a popular choice for home, commercial and technological applications.

Different Uses and Purposes of LED Lights
Imran ali asked:
There is a wide variety of different LED lights available out there. These lights come in various shapes and sizes and are used for a diverse range of purposes. These state-of-the-art lights are designed with resistors as low-power LEDs and they are also available as high-power lights for more robust operation. You can choose from 1W to 3W high-power LEDs, LEDs with wire and resistor, wireless LED remote controller, LED car kits, LED sign boards, LED strips, household bulbs and many more. All these models and styles are used for different purposes including home décor and customization of vehicles. The uses of these powerful lights are unlimited and therefore they are appreciated all over the world.
LED lighting is also used for security reasons and as traffic lights. Since these lights consume very little power they are ideal to be used for long operations or where they are required to remain on for an indefinite time period. LEDs are better than incandescent light bulbs or other traditional lights as they do not heat up very quickly. Almost 80% of the energy consumed by LEDs is converted into light and only some of it is dissipated as heat. Because of the same reason these lights last for a long time and are definitely a cost-effective option.
Basically LEDs are available in three categories: LEDs for cars, LED flashlights, and LED bulbs or strips for home. LED tubes with different patterns are also becoming popular in today’s stylish and high-tech world. These lights can be used to decorate almost anything and they come in red, blue, green and ultra violet colors. LED lights are very bright and can be used in cars, computers, motorcycles and snowmobiles. These lights can be recognized easily from a distance and are therefore used on sign displays such as danger signs and as police warning lights.
LED rope light for household use is yet another wonderful light that one can use for home décor. These lights look pleasing to the eye and can be used to outline the boundary of an object such as a coffee table or TV trolley. They come with 36 LEDs per meter in different colors like red, blue and white. They can also be used as outdoor décor items and as hanging lights on weddings and parties. Since these lights come in exciting colors they are used by many stylish people who love luminosity and brightness.
LED car kits are also admired by a lot of car enthusiasts all over the world. These LED lights create an under-car halo which looks lovely. This LED car kit requires 12V power and comes with 2.1 million color output. It has the ability to display one color at a time and the pattern can be chosen according to the terrain or situation. These lights are made waterproof and they last for many years to come. The best thing about these kits is that they are not very expensive at all. You can get a wonderful LED car kit with remote controller and all wiring for somewhere around $200 which is quite reasonable.
LED lights have infinite uses. Ranging from simple 5mm & 8mm LEDs with resistor to high-power multi-purpose LEDs, these lights are strong and long-lasting. They are designed to operate non-stop for long durations because of extremely low power consumption and very little heat dissipation. They are ideal to be used as ambient and architectural lights as well as medical and convenient lights. Par 38 and Par 20 household LED bulbs are very practical and useful. They can be used for bright kitchen lighting and office lighting.

Solar Led Lights: High-tech Lighting Device
Ernesto Maitim asked:
lights are making a major difference in everything that’s about lighting. From Christmas lights, traffic lights to head lamps and flash lights, those made with light emitting diodes are the ones most popular. What’s more, because it is solar, there’s nothing to plug. Just expose the gadget to the rays of the sun. Indeed, LED and solar power are the team to beat when it comes to coming up with environmentally friendly lighting. One of the popular uses solar led lights is lighting up the exterior of our homes. All LED lights have to do is gather the solar energy all day and have them stored in their solar batteries. Fully charged ones can actually power up the lighting for a maximum of 10 hours. To really optimize the charging capacity of the batteries, just make sure that the solar led lights are totally exposed to the rays of the sun at the longest time. And so it is very practical to buy these types of outdoor solar lighting as their exposure outside your homes, getting all drenched by the sunshine, is what exactly makes them work. Solar Led lights are likewise in the form of lighting for the yard, albeit a good number of lights are necessary to really brighten up the area. And what would the Christmas tree be without those tiny twinkling multi-color lights to cheer up the season. Much of the Solar Christmas lights nowadays are made from light emitting diodes. And so, indeed, the solar Led technology is here to stay, trying to provide bright illumination, adding exciting to our homes and their exteriors – all without the use of conventional power but instead tap the free and clean energy from the sun.

The Move to LED Lighting in Retail
Kevin Dry asked:
It is not widely appreciated that the problem with fluorescent tubes (CFLs) including the new low energy bulbs widely promoted at the moment is that they contain Mercury. The disposal of these types of lighting product needs to be carefully managed to ensure that Mercury (a toxic heavy metal) is captured when disposed of. In addition to the problem of Mercury there is the issue of the starting circuits and power surges these can cause particularly in areas where there are large numbers of fittings being activated at one time.
A move to LED retail lighting can in some cases be a simple replacement of lamp but advice should be sought first. It is often the case that it is not as simple as just remove and replace. Retail LED lighting frequently offers long term cost savings alongside improvements to the retail environment. Key areas of retailing particularly those associate with Pharmacy and especially the promotion of cosmetics benefit strongly from the clean white light that LEDs can offer.
Two other key benefits are on offer with a successful transition over to LED based retail lighting, one of these being replacement costs – particularly in the case of fluorescent tubes and the other being reduction of excessive heat from roof mounted fittings which in some cases can increase costs of running the store’s air conditioning at a high rate than need be simply to loose the heat of the lighting.
New retail lighting solutions include roof mounted LED grids which can replace the traditional multi way fluorescent tube housings found in removable panel type ceiling structures. These same LED grids can be used to perform backlighting functions on promotion or advertising panels. A wide selection of LED tube replacements are now on offer for retail environments and can be used directly to achieve good results.
Many retail lighting distributors and companies are offering LED’s as an alternative without explaining the key differences in the mode of operation or being able to advise on effective drive circuits and power suppliers. Retail companies need to use a good quality supplier of LED’s who can give clear advice on how to avoid the pitfalls that can come from a poorly configured lighting transition. Retail lighting companies such as Selectronic that have been involved with LED’s from before the time their use migrated into the lighting environment can advise on some of the key points of design. A factor they can advise on is LED degradation and ways that it can be managed and planned for as well as offering a wide range of design solutions that can give optimum results.
LED retail lighting is the clear way forward but the route to utilise the technology needs to be considered fully to get the best results. With an expected life of 50000hours, you can be sure that once completed you will have a solution for the long term!

Benefits and Uses of LED Lighting
Imran ali asked:
Are you looking for state-of-the-art LED lighting? This article will educate you about some of the most noticeable benefits of these small yet powerful lights in terms of cost effectiveness and environmental uses. LED is short for Light Emitting Diode. LED lights are made up of small semiconductor diodes that emit blue, green and red light when an electric current is passed through them. Using these three basic colors, all other colors can be produced by combining them in different proportions. Basically these types of lights are used as indicators and for other special purposes like Christmas lighting and for use in flashlights and car lights.
Because LED lights are very efficient in terms of saving energy and cost, they are popular all over the world. All kinds of LED lights are provided by renowned manufactures across the globe. These lights include high-power LEDs, low-power LEDs, sign displays, remote control devices, household bulbs, car kits, rope lights and strips. White-colored LED lamps and energy-saver lights are very common and good at their job. They can operate continuously for hours and hours without becoming dim or weak. High-power and strong LED lights are expected to last for many years.
LED industry leaders have estimated that good quality LED lighting can last for 50,000 to 100,000 hours. Usually these kinds of lights require 9 to 14V DC power which is very low as compared to power required by traditional lighting. Furthermore, they are easy to install and carry around in case you need to move to a new place. They can be stored in a compact storage place and come very handy on special occasions like birthday parties, weddings and Christmas celebrations. Another advantage of these small lights is that they are made water proof and can be installed in any area of your choice.
LED lighting has been found to be superior to incandescent light bulbs and fluorescent tubes in terms of longer and more useful life. These lights also have a faster response time as compared to other types of lights and become fully bright in a matter of microseconds. They can also be used in electronic and electrical experiments where they are required to test passage of electric current through a circuit. They do not contain mercury and are therefore very safe. In fact they can be used to test various circuits where high voltage is expected to be used in order to be safe and avoid electric shock.
Although LEDs are more expensive than other type of lighting, they are very cost effective in the long run. First of all, they save energy. And secondly, they operate for a much longer duration than ordinary fluorescent lights or tubes. Their design flexibility, powerful nature, small size and availability in almost all kinds of colors make them an attractive choice for household use. They are also safe to be used around children as they do not produce much heat. Visible LEDs do not produce any ultraviolet radiation and are therefore useful for a wide range of purposes.
So, you see LED lighting has many advantages over other types of lighting. It is not only cost-effective but also very safe and useful. Different kinds of LED bulbs are now utilized for household use to produce super bright and continuous light. They are also used for entertainment and architectural lighting as part of sophisticated and state-of-the-art interior design. Many people use LED bulbs as portable lights for different purposes. They provide environmental protection and come in many colors including blue, white, red, yellow and green. Red and yellow LED lights are often used in advertisements and sign displays. LED rope lights and strips are used all over the world for wedding decorations and concerts.
