Green Renewable Energy

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.

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.

Nowadays, modern artificial lights are being used to sustain man’s demand for illumination. Who would not want modern artificial lights? In the absence of the sun, people are able to use light with convenience. They can have bright, quality lights by simply turning on the switch. Just as long as you have electricity, you can have limitless use of light.

Since modern artificial lights are being used all the time, energy consumption has also risen. Before, when improvements to lighting systems were not made, artificial lights consumed too much energy. Example is the incandescent light bulb. The problem with this item is that it could not even last for long. Most of the old lighting devices were inefficient and they do not last for a long time.

However, the trend in lighting systems has changed due to the introduction of energy-efficient lights. Since old devices have so many downsides, this new line of lighting systems have been introduced to the market to create quality lighting with minimal consequences.

Saving energy is of great importance to every person. The use of energy-efficient lives paves way for this. Every person in the world should start using them for its enormous benefits. Below are some of the reasons.

Environmental Importance

Global warming has been accelerated due to the high emissions of greenhouse gases (GHG) in the atmosphere. The emission of GHG has been attributed to excessive use of energy in various establishments, including your homes.

Although the use of energy lighting system is not only solution to reduction of GHG emissions, but it is definitely one of the measures you can apply. To be certain if you have an energy efficient lighting device, check for the energy star rating. If they have this, it means Environmental Protection Agency and the Department of Energy guarantees its rating.

Financial Importance

The use of energy-efficient lighting has helped people in saving money. Since devices used consume less energy, this could also mean cheaper electrical bills. Now, you can get a chance to use it for your other spending.

Savings could also be attained through tax credits. Since the economic downturn, the government has given people a chance to reduce their federal taxes by implementing energy-saving practices. This includes use of energy-efficient appliances, as well as improvements. So the next time you make changes in your homes, you might want to include in your list the installation of solar panels or use of florescent lamps and compact florescent bulbs.

Energy efficient lights are the best way to meet your lighting requirements with lesser impact to the environment and to yourself. It can give the same quality (or even better) of light as the old lighting systems but it has benefits that an old device could never compete with. If you do a cost-benefit analysis, it is no doubt that the use of energy efficient lights will show a positive result.

So do not allow yourself to miss these benefits. Make the change now and be a happier homeowner.

Increasingly consumers are turning their eyes towards LED house lights as a way to conserve electricity. But will you really achieve the greatest savings by buying this still expensive lighting now? Or would you be better off to save your money for the time being, or to buy other energy-efficient light bulbs, and use the money you save in electricity to buy LED house lights down the road?

You have most likely seen LEDs before: camping headlamps, LED Christmas tree lights, wind-up emergency torches. How about LED house lights? If LEDs are so efficient, why aren’t manufacturers lining up to sell LED lights for the home, and why aren’t we lining up to buy them?

I wouldn’t try to sell you on LED lights as a solution to high utility bills or as the most ecologically beneficial lighting solution around. Frankly, I think LEDs have a ways to go yet, in terms of function, durability, and economy. There are some LED products you should consider over the next year, such as LED Christmas lights. And you might enjoy trying out a couple of LED light bulbs, if you’re the energy-saving type. But you are going to save more money by keeping with your current lighting, and migrating to fluorescent lights in the next year or so. Compact fluorescent lights, or CFLs, have a payback so short that they’ll pay for themselves before LEDs have matured enough to make CFLs out of date.

LED light bulbs are more efficient than incandescent or fluorescent lighting. The problem is that LEDs have very directed light. An incandescent light shines over a wide area fairly evenly, while LED lights are very focused, so that the area they directly illuminate is very bright, while the further you go from the direct beam, the less light there is. For LED Christmas lights, that isn’t a problem; you just want some shining points of light, which LEDs do very efficiently. But an incandescent or CFL will do a much better job of brightening up your living room than an LED bulb in the same application. The light will be more evenly and broadly spread, and with a warmer color.

When you see LED packaging claims of LED light output, you should be doubtful. A number in Lumens, which indicates light brightness, is misleading for LEDs, because of their focused beam. Lumens levels are read from a sensor placed right underneath the light source. A household LED light bulb at 2 watts may have the same lumens rating as a 50 watt halogen bulb, or as a 15 watt CFL, but the LED lamp may only send a focused light directly under it to the photo sensor, while the incandescent light and CFL will light up a much broader area, and still give that same lumens rating for the area immediately beneath the bulb. This may be the source of a frequent negative comment among LED owners, such as: “The packaging claims this 2-watt LED bulb has the same light output as a 50-watt incandescent bulb but it feels more like a 25-watt incandescent if you ask me.”

When it comes to halogen lights, they are only as efficient as incandescent lights, so the same efficiency considerations apply here. But since halogen lights are typically much more direct than incandescent bulbs, LED lights that are designed to replace halogen lights are both more efficient than the halogens they replace, and work well for the direct light that halogen bulbs provide. You can find LED replacement bulbs for the most common halogen fixtures such as GU10 and MR13, and this may be a good place to start the switchover.

LED house light designers work around the issue of the narrow beam of a single LED, by building household LED light bulbs that are a collection of individual LEDs, with each diode aimed at a different angle, so that a wider area is highly illuminated. This increases the area of full light coverage of an LED light. However very few such bulbs provide the breadth of area coverage of existing incandescent bulbs or CFLs and at the same time are bright enough.

Where LED lights outshine existing bulbs is as replacements for lighting that is (or should be) highly directed. For example, a light in a narrow hallway, where the chief point of the light is to show people their way down the hall, would be a good application for LEDs.

Task lighting is another example of an application where LEDs shine. Why light up your entire work room if all you need to see is the tools on the work bench right before your eyes? A couple of LED bulbs hanging above the work area will do the trick nicely. But you can only cost-justify this in energy savings if you live half your life in the workroom.

LED light bulbs are, in theory at least, very durable, when compared to incandescent bulbs and compact fluorescent bulbs. LED bulb life ranges from 35,000 to 200,000 hours, compared to 1,000 hours for a good incandescent light, and 8,000 hours for a CFL. But I have seen many consumer ratings of LED bulbs that report burn-out within a few days of being switched on. Clearly there are some quality problems still to be worked on - yet another good reason for holding off a couple of years before switching wholesale to LEDs.

Whether LEDs will really live up to their long lasting billing remains to be seen - even the 35,000 hour ones would need to be on 24×7 for 4 years before they come close to reaching their advertised range. And LED lights do dim with age - so while a bulb might have a lifetime of 35,000 hours, it won’t emit its starting light level for the full 35,000 hours - the older it gets, the less light it will emit. LED lights do decline progressively in light intensity and therefore in efficiency, although they will still be more efficient than either CFLs or incandescent bulbs throughout their life.

The “color temperature” of a light bulb, measured in ‘degrees Kelvin’, determines human visual response to its light. You are probably comfortable with the yellowish glow of incandescents at around 2800 Kelvin (2800K), even though fluorescent lighting is closer to the natural daylight temperature of 6000K. Any LED with a temperature of 6000K or higher will seem bluish, and any LED with a color temperature above 4000K will appear whiter than an incandescent bulb.

While homeowners are typically worried about how fluorescent or LED lights can make their rooms look blinding white instead of the comforting yellow glow provided by incandescent bulbs, you should remember that a little sacrifice in color temperature will put a big dent in your electricity bill. Be a trend-setter, not a trend-follower - start converting your home lighting to true daylight colors, whether with CFL lights or LED light bulbs. You will be helping your family and friends to switch over, when they find out they won’t be the only ones with a slightly bluer light hue in their homes.

Whether you switch a few of your lights to LED lights now, or let the technology and reliability improve, you can count on the fact that LEDs will play an increasing role in lighting our houses in the years ahead. I personally think it makes sense to wait, except in certain special lighting situations where the direct, high-color-temperature light of LEDs is what you’re after, and where money is no object. If you just want to save money - or to cut your energy use for environmental reasons - an equal amount of money spent on CFLs, or most other energy efficiency upgrades, will cut your energy bills and carbon footprint more than buying the LED lights now available.

This article assumes you are already convinced about going ‘LED’ but want some specific product ideas. In this article I would like to present 3 general product categories that can be used to begin your transition to LED lighting. Each idea is going to have more than one product possibility that can be tailored to your exact needs. Also, each individual product itself may various options. We will discuss some of these options and how you should go about selecting each. This is important as LEDs are a new technology and not everyone knows what options are available or even exactly how to choose them.

The first product category is LED PAR Lights. The word PAR is an abbreviation for parabolic reflector. This is actually not applicable to LEDs since they have lenses and are no longer dependent on reflectors to create directional light. In fact the lenses on LED lights are much more efficient than reflectors. LED light is directional and can be controlled precisely with the use of lenses. As long as we are talking about lenses that is going to be the first thing you will have to make a choice on. LED PAR lights can be purchased with various lens angles. Usually you will have choices like 30, 45, and 60 degree lenses. The lens controls the angle of the light. The tighter the angle the more concentrated the light, and the wider the angle the more diffuse the light, but a greater area will be illuminated. A 45 degree angle is possibly most all purpose but aesthetically, and mathematically thirds are nicer or a 60 or 30 degree angle. Use 60 for general purpose and 30 for spotlighting.

Next when you order a PAR light you would have to select the color. One of the advantages of LEDs is that you can select precisely the color of the light. Common options are warm white 2,800 – 3,800K, commercial white 4,000 – 5,000K, and pure white 6,000 – 6,500K. Each color has its advantages depending on the situation. Warm white is best for creating atmosphere, while pure white is a bit brighter and produces more lumens per Watt. For security lighting you would use pure white, for a bar most likely warm white.

Finally, in the case of LED PAR lights you would have to select the number of Watts. I generally advise multiplying by 5 to 10 when comparing to incandescents. So a 5 Watt LED is like a 25 – 50 Watt incandescent. Technically the number should be 5 but in addition to producing more light LEDs focus it better, and this can increase the multiple to about 10. When making your selections keep in mind it is difficult to stock every possibility. If you want commercial white with a 45 degree lens you may have to put in a request. Try to plan in advance slightly, and the extra wait is well worth it.

The next category is LED recessed lights. LED recessed lights offer similar options on color and lens angle. In the case of ceiling lights you would have to choose the number of LEDs. Common is 3 Watt LEDs so for example you could get lights with 3 LEDs for 9 Watts or 5 LEDs for 15 Watts and so on. You can use the above multiplication to decide on the number of lights. LED recessed lights generally come in their own housing and so are easy to install. LEDs do not produce much heat, but remember to not put insulation directly on top of the light. I don’t think you were going to do that. LED recessed lights can have adjustable heads and hardened glass coverings. Using a grid of such lights to light a large area can create a nice effect. Properly placed LED recessed lights can be a nice addition to your home lighting.

Finally, I would like to briefly mention light bars, and light strips. These can be used for accent lighting, cabinet lighting, and wall lighting. Again properly placed these can be used to achieve some very nice effects. If you are designing a new addition to your house you may want to use light bars or light strips to highlight the features or add a more subtle lighting.

Lighting a home can be a complex task, since a good lighting system can require different lights for different purposes. One of the things that should be considered in a lighting system is what kind of lights to use around the outside of the home. Right now, the homeowner has three choices: incandescent bulbs, halogen bulbs, and outdoor LED lighting.

Incandescent bulbs and halogen bulbs are currently popular inside, but for outdoor lighting, LED lights hold some distinct advantages. If you haven’t heard much about the advantages of LED outdoor lighting, read on and find out what makes these little devices so great.

LED Saves Energy

One of the advantages to LED outdoor lighting is that LEDs require a relatively small amount of wattage to produce the same amount of light as an incandescent or halogen bulb
. Because of this, LEDs are low-energy solutions for lights that may be on for more than a few hours each night.

What this means is that those who are interested in using less electricity for environmental reasons, LED outdoor lighting will be the solution you’re looking for. And for the rest of us, LED outdoor lighting translates to lower energy bills.

LED Runs Cooler

Another distinct advantage to LED outdoor lighting is that while other kinds of bulbs produce heat energy as well as light energy, LED outdoor lighting only produces light, which means bulbs remain cool to the touch. This makes it safer to put lights in reach of little hands, for households with children. It also means that these lights are ideal for applications such as landscape lighting, where placing light bulbs that run hot near plants could spell disaster.

LED Lasts Longer

LED outdoor lighting will last longer than both incandescent and halogen bulbs, which are another strong selling point of these lights. And even better, when these bulbs do start to go, they will simply start to slowly dim, giving a homeowner a heads-up that they need to change their bulbs.

Compare this to incandescent bulbs, which break inside when they burn out, or halogen bulbs, which blink irritatingly as they start to go, and you’ll see that LED outdoor lighting will be better in the long run.

While mentioning the longevity of LED outdoor lighting, it is good to note that because LEDs are manufactured as one solid piece, with no glass or filaments to break, these lights are resistant to shock, vibration, and impact, which makes them hardier than the average lightbulb. So, for a low-energy, low-head, and long-lasting lighting on the outside of your house, turn to LED outdoor lighting.

We all have access to a free, bright and renewable source of light – the sun. A great way to utilize it after dark is with solar lights. Solar lights have come a long way in the last few years and offer a wide array of styles, shapes and materials. They are powered by rechargeable batteries and can light up an area for the entire night. The lights are powered by light emitting diodes (LEDS) which rival hard-wired lights. They are very durable and can last for up to 1,000 hours.

Solar lights have several advantage over hard-wired lights some of which are:
Require no wiring
Powered by the sun
Fast and easy to install
Energy saving
Recharged by solar panels under sunlight
Light turns on automatically when dark
Super bright LED for brighter light output
Rechargeable Ni-Cd AA battery which are included
Safe water resistant
CE certified
LED bulb never burns out
Up to 10 hours of light when dark
Corrosion resistant
LEDs can last up to 100,000 hours
Batteries are rechargeable and should last for approximately 2 years before replacing

Solar Lights are totally free standing, simply fit the light components together, press the spike into the ground or screw on to the wall mounting, it’s that simple! Add them along pathways or set them up as spotlights. Add some unique lights and be the talk of the neighborhood.

There may be even more advantage to solar lighting based on your application. They do offer a real alternative to hard-wired lighting and are real versatile. They allow you the option to spending time outdoors after dark and allow you to light up any areas you may want. Solar lighting is a very versatile way to light up your yard.

Jerome Sturgeleski is an avid outdoors person and loves to stay out in his yard after dark. He lives in Minnesota so time outdoors is limited to just a few months of the year. After completing a landscaping project he thought the must be a way to light it up so he could enjoy in on those evenings out. He added some solar lights and liked it so well that he decided to start a website and sell solar lights so others could also add them and enjoy their outdoor spaces well into the evening. He started a website in May of 2005 called http://www.solarlightspro.com to allow people to see what types that are available.
