LED LIGHTING SYSTEMS

Today when great persons in the world are worried about the environment problems caused by pollution, LED lighting systems will prove a boon because the industries, eco-friendly firms; simply by retrofitting a building can significantly reduce carbon emission and save number of trees with guarantee of five years for the light installed. Light Emitting Diode (LED) is a device which emits light on passing of an electric current through it.

The fact can not be denied that nearly 2 billion people worldwide and half of the population in modernizing India does not have access to reliable and clean lighting. Use of kerosene or fuel wood is inadequate for light as well as pollutes the homes and the environment. Emerging technologies in LEDs promise for reliable, inexpensive lighting to the poor and needy. The low energy consuming white LEDs housed in a lantern type case powered by a small storage battery charged either by grid or by solar would make the lighting.

This will help people to lengthen the productive day for many of their daily household tasks or lucrative jobs by extending the hours of light. These hours “earned” have been estimated tobe worth nearly $25 million a day and $100 billion a year. From the sets of Broadway to television studios, LED lighting systems has become an ideal alternative to traditional lighting sources for entertainment applications. As energy efficient light sources, LED lighting provides a dynamic impact, while eliminating the need for maintenance-intensive color gels and filters. Keeping in view the ever increasing prices of energy as well as energy    crisis, the U.S. President Mr.Obama is taking keen interest in energy efficient lighting. The fastest and the best way are to use energy saving bulbs to reduce consumption. Fine quality, high powered LED street lights replace conventional ones and bring down electricity bills up to 44 lakhs over a period of 10 years, since street lights are operating for 12hrs a day. The area where UV or IR radiation is to be avoided, LED spot light is an excellent alternative, widely used in factories, advertising boards, buildings, gardens. In this period of Global Recession, when the Management is taking all the possible steps to bring down the costs, LED down lights and tube lights are highly energy efficient and excellent option to cut electricity bills because it is only the government offices, malls, theatres, libraries, gardens, parks etc. where light consumption is unlimited and inconsiderable. Undoubtedly, the rise of the LED, which has just begun, is set to sky-rocket in the coming years. That’s why, even in this economic crisis, the companies are investing constantly and brusquely.

Thanks to the human brain which brings solution to entire crisis.

General Issues in LED Lighting – How to choose your LED?

Choosing the adequate lighting for your home or office can be quite a challenge these days. The latest improvement of LED lighting techniques have made it possible for all of us to use it as a main source of lighting, other than a simple signalling light in our everyday gadgets. Still there are a number of issues reoccurring when you choose LED lights, and these issues often lead to many people ending up with fluorescent lights on the long run.

It is already a huge development in our thinking if we do not consider the price of a product the only decisive factor. Incandescent lights would definitely win by far, however often we have to replace them, however much energy they consume or are ruining our environment.

Now, let's try to sort this out together. I think we might all agree that unless we are really bunkered and we need a light from a pound shop immediately the traditional incandescent lights, traditional or halogen, are out of question for the reasons previously mentioned: huge energy consumption with the conversion rate of 5% of energy into light (the rest of it is emitted as heat) and extremely short lifespan compared to any other source of lighting. Fluorescent lights are much more energy efficient, converting roughly 20% of the energy into light, and have longer lifespan of 1000 to 3000 hours depending on the quality and type of lighting. As far as greenness goes, they could be much more environmentally sound. The chemicals in these lights (Argon and Mercury) are highly contaminating.

On the other hand, light emitting diodes (LEDs) convert roughly 80-90% of energy into lighting, and only the rest is emitted as heat. Their power consumption is therefore very low in order to create the same amount of light, and they remain cool, you can touch them any time. They also reach their full brightness immediately, and are the most environmentally friendly lighting solution currently available on the market.

When it comes to buying LED lights, distributors try to get us pay a much higher price for a simple light bulb on your desk. This is already a point where most of us stop, having to pay not simply a price for a bulb but basically invest into it, but as long as we are prepared to do that we must look at the range of products carefully. What are the most frequent questions about LEDs? 1. Do they produce significant light to replace your current bulb? 2. How long can they be used during the day? 3. Do I need any extra gadgets or methods for application? 4. Are they dimmable? None of these questions are trivial if you are a user and you are looking to replace let's say more than one of your light bulbs. Also the point of using LED is the extremely long lifespan they have. Not applied properly they can lose most of it, and your money just goes down the drain. So, let's examine these issues one by one.

Do LEDs produce significant light to replace my current bulb and how many hours can they work?

There are three major types of diodes, the low power ones, the power or SMD techniques and the high power ones. Low power ones are good solely for decorative or mood lighting, would never really produce enough light for reading or to replace any current light bulb. Also to keep their lifespan, you are simply not allowed to use these for longer than a few hours a day. Mind that these low power LEDs are the ones mainly available in DIY stores at a low price with somewhat misleading advertisements for those who are not into the topic. Always check what you buy: the distributors usually indicate the Wattage of the traditional light the LED is supposed to replace. SMD power and high power technologies are both adequate to replace traditional light bulbs. High power LEDs are suitable for constant lighting, so good for commercial use. The light emitted by LEDs also depends on the size of the diode itself, and the chip included. Quality chips increase the lifespan of LEDs radically from 30 000 hours to 50 000 even. That almost means that these bulbs will only be replaced by the next generation in your family, now, that sounds like an investment worth making.

Do they require a special application?

The answer is: not necessarily. There are LED bulbs for 220V, which you simply replace with twist and turn, but there a couple of LEDs working on lower Voltage, usually 12V or 24V. If your lights run at 220V you definitely need a transformer / power supply to apply these lights. Applying the right transformer with your LEDs is crucial not only from the point of view of operating the lights but keeping their expected lifespan. Since the variety of solutions is nearly endless, you have to check the right kind of transformer with the distributor or the technician.

Dimmability

Dimming LEDs needed a brand new technology but is now available. They used to create LED dimming by controlling the frequency of switching the lights on and off. With the new techniques, certain LED spots and bulbs even work with previously set up systems for halogen lights depending on the dimming system by making them suitable for leading edge dimming technology.

The main purpose of the article is to encourage the reader to think before buying. I have to admit finding the best solution is not really made easy by many distributors. Sadly I find several distributors simply selling LEDs with false technical details, mainly about the light output (measured in luminous flux or lumen) and the performance of the lights, which is anything but consumer friendly attitude. Try to find reliably distributors by checking their details, the ones with false details usually catch the eye, like products with the same LEDs emit different amount of light, or have completely different performance… ask them why! Don't be shy if you do not understand the difference, their job is to tell you. Also, always check different distributors, and challenge them with each other. Remember that you might actually invest into this for the following generation!
