LED lights are finding wide range of applications in the field of lighting. Where ever incandescent bulbs or CFL Bulbs were in use, LED bulbs are appearing as a replacement. For all purposes of home applications various types of LED fittings and fixtures are available in the market. The headlights of the cars, motorbikes, all kinds of indication lights are of LED today.
Whether it is street lighting or any type of decorative lighting, LED light fittings and LED bulbs/lights are there. Today there are a number of varieties of LED lights that are specially used for purposes like flood lights, spot lights, down lights, etc and many more Mars Hydro 300w . The conventional sources of lighting like fluorescent, incandescent or halogen fittings have given way to the latest LED light fittings every where.
LED lights are the most durable ones of all versions of lightings. There are no glass components or filaments in LED bulbs as in the case of incandescent lights. There are no toxins or harmful or hazardous gaseous materials in LED as in the case of CFL lights. While, the previous versions of the LED bulbs were able to produce red light of low density, today, we have LED lights with wider choices and you can purchase these in many different advanced versions too. The innovations in the field have brought in tremendous far reaching improvements.
You might have possibly utilized LED light bulbs long before, you just didn’t recognize it. They are evident in everyday tools such as TVs, tracks, remote system, DVD players, and calculators. Presently LED light bulbs are finding their unique role into residences, due mainly to soaring power costs. Irrespective of its ubiquity, however, LED light bulbs utilized for general home light bulbs are still quite new.
Nearly all American homes make use of ordinary incandescent and fluorescent light products, and use up about 25% of total electrical power consumption on lighting alone. As per the US Department of Energy, the application of new lighting technologies helps to reduce lighting electricity use in family homes by 50% to 75%. A greener way more cost-effective option is to use LED light bulbs, the most current innovation in home lighting products.
LED or light-emitting diode is a kind of semiconductor. LED bulbs were being first commercially initiated in laboratory test tools, and only afterward in radios and handsets. The main shapes of LED lights are mini, high powered, and custom fashioned.
A number of advantages goes with using LED bulbs. When compared to fluorescent and incandescent light bulbs, LED bulbs close to 1/10 less power consumption. LEDs also persist 50 to 100 times longer as against standard bulbs, or supply 100,000 hours’ use against 10,000 hours for CFLs or compact light bulbs. LEDs are much more compact in size and are sturdier. Because they are composed of solid state parts, LEDs are hard to spoil, unlike breakable CFLs and incandescent bulbs.
One-hundred-and-thirty years ago, Thomas Edison completed the first successful sustained test of the incandescent light bulb. With some incremental improvements along the way, Edison’s basic technology has lit the world ever since. This is about to change. We are on the cusp of a semiconductor-based lighting revolution that will ultimately replace Edison’s bulbs with a far more energy-efficient lighting solution. Solid state LED lighting will eventually replace almost all of the hundreds of billions of incandescent and fluorescent lights in use around the world today. In fact, as a step along this path, President Obama last June unveiled new, stricter lighting standards that will support the phasing out of incandescent bulbs (which already are banned in parts of Europe).
To understand just how revolutionary LED light bulbs are as well as why they are still expensive, it is instructive to look at how they are manufactured and to compare this to the manufacture of incandescent light bulbs. This article explores how incandescent light bulbs are made and then contrasts that process with a description of the typical manufacturing process for LED light bulbs.
So, let’s begin by taking a look at how traditional incandescent light bulbs are manufactured. You will find that this is a classic example of an automated industrial process refined in over a century of experience.
While individual incandescent light bulb types differ in size and wattage, all of them have the three basic parts: the filament, the bulb, and the base. The filament is made of tungsten. While very fragile, tungsten filaments can withstand temperatures of 4,500 degrees Fahrenheit and above. The connecting or lead-in wires are typically made of nickel-iron wire. This wire is dipped into a borax solution to make the wire more adherent to glass. The bulb itself is made of glass and contains a mixture of gases, usually argon and nitrogen, which increase the life of the filament. Air is pumped out of the bulb and replaced with the gases. A standardized base holds the entire assembly in place. The base is known as the “Edison screw base.” Aluminum is used on the outside and glass used to insulate the inside of the base.
