LED 101
Many people are not aware that LED Lighting is in fact quite an established technology having been originally used in the 1960′s .
LED light bulbs were originally used as a alternate for incandescent indicators and displays in laboratory apparatus and ultimately in TV’s, watches, radios and calculators. LED costs have only recently dropped a sufficient amount to make them viable for residential and commercial markets. LED home lights can consist of anything from outdoor to Christmas lights .
EFFICIENT POWER…
Ordinary light bulbs only convert around 10% of the electrical energy it consumes into light with the rest being output as heat, LED lights on the other hand converts more than 70% into usable directional light making them far more efficient .
LED’s also last for more than 50,000 hours, substantially longer than both incandescent and CFL. Used constantly they will last nearly 6 years .
ENVIRONMENTALLY FRIENDLY…
LED lighting is safe, environmentally friendly and contains no toxic mercury.
Because LED’s use so little power their environmental impact is drastically reduced – there is no need to burn extreme coal etc to make electricity as consumption is reduced .
LED’s are designed to last for 50,000 hours more resulting in a lesser amount of resources being used as there is no longer the need to replace old bulbs that gets thrown into the dustbin The LED life cycle is also healthier for the natural world because of their long lifespan there is much fewer garbage from burn out LED bulbs and this reduces the load on recycling depots and garbage dumps .
The below is a short history of man-made light
Our entire history of light has been an inefficient one! Why? Because we have always used heat as a source of light – we have used wax, oil and gas to burn in order to generate light. This process is highly inefficient as most of the energy is wasted producing heat and not light. Even fluorescent lights uses a type of gas which is electrified to heat up and produce light .
The basic method has been ” Heat it up and it glows”
For more than 120 Years, incandescent light bulbs have brightened and warmed our lives. Electric powered bulbs were a major improvement over candle, gas and oil light sources – but they are extremely ineffecient. Up to 90% of the power going into the bulb is converted to heat!
While fluorescent lights are far more economical than incandescent bulbs the fact that they contain mercury, one of the most poisonous substances on earth, makes them a hazard to use and makes disposal very dangerous. Mercury seeps into the ground and contaminates water and soil for thousands of years .
In the past 4 years a new light source has emerged that is sufficiently bright and cost-effective to be used for general illumination.
LED characteristics – efficient, long lasting and non-toxic makes them the most exciting development in man-made light ever! . The first commercially viable LED was introduced in 2006 and now lighting manufacturers around the world are producing a whole new class of LED products for general illumination.
Light Emitting Diodes (LED’s) are solid state lighting components. They have no moving or fragile parts and can last for decades . LED’s are many times more cost-effective than Incandescent Bulbs. Just as vacuum tubes were replaced with solid state components, the last remaining vacuum tube light bulbs are being replaced by solid state components.
LED lights are essentially a circuit board, when electrical energy is passed through these components it produces and electronic light .
The first LED’s for commercial applications were red. They functioned as on/off indicators in electronic devices such as VCR’s, calculators, strereo systems and even automobile sub-systems. Eventually LED’s were produced in green and amber as well. The major breakthrough can in 1989 when CREE, INC. of Durham in the United States, started shipping the first commercially viable blue LED based on silicon carbide. The blue LED enabled white LED’s to be made because mixing red, blue and green light produces white.
Today a more efficient and cost effective white LED is revolutionising the lighting world. The white LED, based on a blue LED chip coated with phosphor is bright and economical enough to be used in general illumination.

LED Lights – The Future of Lighting
LED lighting are a specific type of power reducing, eco-friendly illumination system. LED lighting consumes a smaller amount electricity for their functioning as they generate very little temperature, so a much bigger portion of electricity goes into creating light rather than wasting energy. Researches on LED lighting have shown that they recover up to 65 percent of energy in contrast to other bulbs. This kind of energy-efficient bulbs is an ideal method for dropping the amount of carbon exhaust in the atmosphere. So it can be believed that LEDs will eventually supplant all sorts of lighting – cfl’s, halogen, and incandescent in the near future.
LED bulbs are produced through movement of electron’s inside its semiconductor composition. They lack filaments. This science is the chief reason behind its longevity. A LED lamp can very effortlessly last for ten years. What is more, they are shock, vibration and moisture resilient. These bulbs do not include dangerous substances like lead and mercury and are also free from breaking dangers. All these details make them a dependable and prudent source of light .
By changing to a LED lights you provide yourself a realistic opportunity on reducing the expenses towards your electrical charge. Using LEDs you will cost less and provide more payback in the long run. Also it would give you the gratification of giving your modest bit in the management of defending the earth.
These times the LED lighting are appearing in diverse sizes and colors. The colors can vary anything from white, blue, yellow, green, and amber. As well, the color altering LED lamps have given the LEDs a new place. The shapes are cool, stylish and contemporary . So jointly with an eye-catching shape plus the usefulness characteristic, it comes as a comprehensive parcel in the palms of the customer.
So spending on LED lamps can be termed as a – ‘bright, eco-friendly, long-time investment.’
