LED Lights – A Brief IntroductionThis E-Book contains the following information for Lighting professionals anddomestic users about the latest revolutionary LED Lights which are very energyefficient in the market. The History of LED The Uses and Benefits of LED Light Bulbs How LED Lights Can Help Reduce Your Carbon Footprint Things to Consider Before Buying LED Lights
The History of LEDWe are hugely dependent upon technology and sometimes take it for granted. It is alwaysworth reminding ourselves where it all began so we can fully appreciate how lucky we are.Take Light Emitting Diodes (LEDs) for example. They have come a long way in a relativelyshort time. When they were first used as low-intensity light emitters in electronic devices, itis difficult to believe anyone would foresee them one day lighting our homes. But here weare!The scientific principle behind the LED is electro-luminescence. Electroluminescent materialsemit light when they receive an electrical current. The phenomenon was first discovered in1907 by H J Round. The discovery of the light bulb by Thomas Edison predates this by manyyears.Nick Holonyak is widely considered the father of the LED. He developed the first practicalLEDs in 1962 and it was in the very same decade that they became commercially viable. Atthis early stage they were used as electronic components in computers, remote controls andother appliances.It would be a few more decades until LED technology was developed to encompass theentire visible spectrum of light, therefore making them a viable alternative to other forms oflighting. Modern high-power LEDs producing high intensity white light were developed in the1990s by Japanese manufacturers, and it would not be long after that before LEDs beganreplacing the light bulbs in our homes.LED Lights have revolutionized the lighting industry. They are many times more efficientthan traditional forms of lighting such as CFL bulbs, etc. This is because LED Lights convertmore of their energy into useful light and waste less as heat. About 90 per cent of LEDBulbs energy is turned into visible light. The lifespan of an LED Bulb and lights is also a lotlonger than the older forms of lighting products. You can expect them to last up to 30,000hours, with some more recent models, such as the GU10 24 SMD LED, lasting as long as50,000 hours. Thats why the phrase long lighting life get attached with the LED lights andbulbs.LED Lights are now available in a wide range of shapes and sizes. You will be able to findthem in the most common lighting fittings including GU10, MR16, E27 and B22. They arealso available as flexible LED Tape, which is becoming a popular substitute for older formsof effects lighting.The Uses and Benefits of LED Light BulbsLED stands for Light Emitting Diodes. This technology has actually been with us for a verylong time. They began life as components in electronic appliances, such as televisions,computers, remote controls and digital clocks. Now they are even lighting our homes. Youwill hear a lot of people claiming that LED Light Bulbs are revolutionising the lightingindustry, but you may also be wondering why exactly this is. The advantages they hold overconventional forms of lighting are many and varied. This article will take you through a fewof them.Energy Efficient
One of the main drawbacks of traditional lighting is that a lot of the energy they consume iswasted. In fact, only about 10 per cent of a typical light bulbs energy is converted intouseful light, the rest is lost as wasted heat. This is largely due to their design and thefilaments they use. LED Lights do not have the same problem. They convert about 90 percent of the energy they use into useful light. This means they use a lot less energy inachieving the same brightness. It only takes about 4 watts in energy for an LED Bulb toachieve 60 Watts of brightness. This is even more impressive than Compact FluorescentLamps (CFLs).Long LastingThe average lifespan of an incandescent bulb is about 1,000 hours. This is because theirdelicate filaments heat up and burn out quite quickly. As such, you can expect to bechanging your bulbs a couple of times a year, a cost that mounts up over time. Becausethey dont rely on a filament, LED Bulbs can last much longer. They last anywhere between30,000 and 50,000 hours. As such, you will only be changing an LED Light once over aperiod of several years.CostOne of the biggest drawbacks about these Bulbs is cost. The initial asking price for an LEDBulb is significantly higher than incandescent. However, you should not be put off by this.These are designed to pay for themselves overtime, so instead of baulking at the immediateprice, you should calculate the cost over a long period of time.The actual cost of an incandescent bulb is a lot more than its initial price. Overtime you willend up paying much more in labour expenses, replacement costs and electricity bills.Due to their low energy use and longer lifespan these Lights begin paying for themselvesvery quickly by lowering your electricity bills and maintenance costs.VersatilityLED can be manufactured to very small sizes, which makes them a lot more versatile. Mostof these Lights are classified as retrofit. This means they will swap straight over with yourexisting bulbs without the need for rewiring. The range of LED Light Bulbs now include allstandard light fitting, such as 240V GU10 and12V MR16 Spotlights, and domestic fittingssuch as B22 Bayonet Cap and E27 Edison Screw.DurableLED Lights are actually a lot more durable than standard light bulbs. Incandescent bulbs andhalogens are quite fragile, particularly their delicate filaments. LED Light Bulbs canwithstand a lot of punishment before they break, making them even more versatile.The energy efficiency and cost effectiveness of LED Light Bulbs is really driving demand andin the near future you can expect them to be used in even more commercial and domesticlight setups. It really is time to say goodbye to wasteful incandescent bulbs and ephemeralCompact Fluorescents.
How LED Lights Can Help Reduce Your Carbon FootprintCarbon Footprint is a well-known ecological phrase that relates to human activities andtheir impact on the level of greenhouse gases in the Earths atmosphere. To be moreprecise a Carbon Footprint is defined by the Carbon Trust Website as a "measure of the totalgreenhouse gas emissions caused directly and indirectly by a person, organisation, event orproduct."Everything we do in our day-to-day lives, from switching on a light bulb, to driving a car, tousing a product, all contribute to our individual carbon footprint, which, in turn, goestowards making up the collective footprint of the nation.What types of Carbon Footprint are there?An individual Carbon Footprint is made up of two parts; a primary and a secondary.A primary footprint is a measure of the CO2 emissions produced directly from the activitiesof an individual or organisation. These are carbon emissions that we have direct control overand can actively reduce by, for example, monitoring and moderating our use of energyintensive appliances such as light bulbs and electrical appliances.A secondary Carbon Footprint is the indirect CO2 emissions created across the entirelifecycle of a product. This includes anything from the extraction of raw materials andmanufacturing, right through to its use and final reuse, recycling or disposal. At every phaseof its existence a product is contributing to an indirect Carbon Footprint of this sort.Why is it important to reduce our Carbon Footprint?During the 18th and 19th centuries the western world underwent a period of sustainedindustrial growth that has become loosely referred to as the Industrial Revolution. While it ispossible to identify lasting social, economic and cultural changes from this period, one of themost profound impacts has been environmental. Population growth, urbanization,industrialization and an increasing dependency on fossil fuels and, more recently, consumerproducts, have all contributed to larger and more far-reaching carbon footprints in themodern world.Nowadays it is more important than ever to reduce our Carbon Footprint. Developedcountries, such as the United Kingdom, are producing more and more carbon emissions.However, some of the worlds largest contributors are actually developing countries such asChina and India that are only now undergoing the same period of industrialization that weonce did.By leading the way we can set a precedent for cutting carbon emissions in the years tocome!Start with your lights and the rest will follow.The majority of electricity in the UK is produced by the burning of fossil fuels such as coal.By lowering the amount of electricity you use, you will subsequently lower your carbon
footprint. The lighting in a typical household constitutes about 10 per cent of your annualelectric usage.With the development of long-lasting, energy-efficient LED Light Bulbs, reducing this figureis incredibly straightforward. They are one of the easiest measures you can take to makingyour house more energy-efficient and help you start reducing your footprint today. A lot ofpeople are deterred by factors such as cost and effort, but replacing your light bulbs couldnot be easier. Most have a like-for-like retrofit design that allows them to replace olderincandescent and halogen bulbs without the need for refurbishing your lighting system.LED Lights use 90 per cent less energy than a typical incandescent bulb, which will greatlydecrease you primary footprint. As LED Lights also last up to 20 times longer than atraditional bulb they will also help you reduce your secondary footprint as you will findyourself using fewer replacement bulbs overtime.Energy efficient LED Lights wont just reduce your carbon footprint; they will also reduceyour energy bills.As soon as you see how easy and pain-free converting to LED Lighting is and what animpact it can make on your Carbon Footprint you will be just as eager to search for newways to make your lifestyle more eco-friendly.Things to Consider Before Buying LED LightsThe internet is now one of the best places to buy low energy LED Lights. However, beforeyou buy there are a few things worth considering. Despite what everyone says, buyingthese Lights requires some careful consideration. It isnt difficult, but at least you will avoidthe hassle of having to return your LED bulbs if the event arises. By following some simplesteps not only will you buy the best LED lights every time, you will also be spending lessmoney on your electricity bills in no time.The first thing to check when buying theshi-techLlghts is the fitting. Check the fitting on your existing bulb. This will be in the form of acode. For example it might be GU10, MR16 or B22. LED lights have the same fittings asconventional halogen and incandescent bulbs, so by getting this right straight away you willknow what you are looking for and what questions to ask when you need to. You canidentify your fitting by either checking the bulb itself or using a fitting guide, which mostwebsites now provide. Simply compare your fittings against the high resolution images.Next you need to check wattage when you by LED lights. Find out what wattage yourexisting bulbs are, either by checking the original packaging or, if you no longer have theoriginal packaging, by looking at the bulb itself. Light bulbs will usually have the wattageprinted somewhere on their surface. Once you know the wattage of your existing bulbscompare these with the equivalent wattage which can be found either in the productspecification or on the product images. An equivalent wattage simply describes the wattageof the halogen or incandescent bulb the LED lights are designed to replace. For example aGU10 LED (48 Cluster) uses 2.5 watts, but its equivalent wattage is 30 watts. This meansthe bulbs is designed to replace a 30 watt halogen.The final thing to check is the size of the bulbs. One of the biggest problems customershave is that they get home and find that their brand new LEDs dont fit inside their recessedceiling fittings. This is because some GU10 LED Bulbs are made to slightly largerspecifications to accommodate heat sinks and drivers. Before you buy make sure you
measure the size of your fittings and compare these with the sizes quoted on the website inthe product specifications area.By following the aforementioned advice you shouldnt have any trouble finding exactly whichbulbs you need and swapping them over.Buy LED Lights such as GU10, MR16, etc today and begin saving immediately on yourenergy bills.References:http://www.wholesaleledlights.co.ukhttp://www.ledstriplights.co.ukhttp://www.ledtape.co.ukhttp://www.onlineledlights.co.ukhttp://www.ledgu10.co.uk
