LED is an abbreviation for Light-Emitting Diode. LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs they don't have a filament that will burn out, and they don't get especially hot. LEDs use small, powerful sources of light that illuminate when electrons move through semiconductor materials. In more technical terms, they have a two-lead semiconductor light that resembles a basic pn-junction diode, except that an LED also emits light. LED is being used in the industry to replace incandescent light bulbs due to the multiple benefits and advantages that LEDs encompass.
Highly Efficiency: LED is considered to be today’s most efficient way of lighting, with an estimated energy efficiency of between 80-90% when compared to traditional lighting and conventional light bulbs. This is only one of, but perhaps the best, reason to use LED lights. They save you money on power and save the environment. Conventional light bulbs squander the majority of their energy as heat. An incandescent bulb gives off 90% of its energy as heat, while a compact fluorescent bulb squanders about 80% as heat. LEDs remain totally cool, thus wasting less energy. An LED bulb that produces similar amounts of light to an equivalent incandescent produces about 5 percent of the heat.
All incandescent and fluorescent lights produce light that flows in all directions, wasting light as well as heat.
80% of the electricity fed to an LED is converted to light.
20% of the electricity fed to a conventional bulb is wasted.
A building’s carbon footprint from lighting can be reduced by 85% as a result of exchanging all existing incandescent bulbs for new LEDs.
Low power requirement: Several varieties of LED lights can be operated with battery power supplies. In recent years, they have become bright enough to use in familiar lighting applications. And as the price of wholesale LEDs has dropped, the power-saving properties of LED lighting have become more cost-effective, making LED lighting far more efficient than any other home lighting option. LED bulbs use less power than compact fluorescent bulbs, so replacing compact fluorescent bulbs in your home or business will help to reduce both heat and power consumption.
Long Lifespan: An LED can function for decades when installed properly as LED bulbs can last much longer than compact fluorescent bulbs. Compact fluorescent bulbs can last 8,000 hours while LED bulbs can last around 50,000 hours. LED lifetimes are rated in a different way than conventional lights, which go out when the filament breaks. The long operational lifetime helps achieve even more energy efficiency, especially in the large scale, like in urban infrastructure projects, such as cities, railroads and airports. LED light bulbs could be a cost-effective option for lighting a home or office space since they have an extremely long lifespan.
Ecologically Friendly: LED lights contain no toxic materials and are 100% recyclable, and will help you to reduce your carbon footprint by up to a third. In contrast, the majority of conventional fluorescent lighting bulbs contain a multitude of materials such as mercury, which are dangerous for the environment. A low-voltage power supply is adequate for LED illumination thereby making it easy to use LED lighting in outdoor settings, or by connecting an external solar-energy source, which is a big advantage when it comes to using LED technology in remote, rural areas. Another great advantage is that LED illumination produces little infrared light and almost no UV emissions so LEDs are highly suitable for goods and materials that are sensitive to heat due to the benefit of little radiated heat emission, as well as for illumination of UV sensitive objects such as museums, art galleries or archeological sites.
Durable Quality: LED lights are resistant to shock, vibrations and external impacts therefore they make great outdoor lighting systems for rough conditions and if exposure to weather such as wind, rain. As LED lights are resistant to shock, knocks, vibrations and external impacts, they make excellent outdoor lighting systems especially for rough conditions and exposure to weather such as wind, rain. Even external vandalism, traffic related public exposure and construction or manufacturing sites will benefit from using LED lights.
Flexible Design: LEDs can come in a variety of shapes and sizes, while always producing a highly efficient illumination. Individual LEDs can be dimmed, resulting in a dynamic control of light, color and distribution. LEDs measure approximately from 3 to 8 mm long and can be used singly or as part of a collection. The small size and low profile of LEDs permit them to be used in spaces that are considered too small for other light bulbs.
Operational in Extreme Temperatures/Weather: LEDs are perfect for operation in low outdoor temperature settings. For fluorescent lamps, low temperatures may effect operation and present a problem. LED illumination, however, operates well in cold settings, making them ideal to be used in outdoor winter environments or in freezer rooms. They also perform well in extremely hot settings, such as boiler rooms and ovens. LEDs can be designed to be waterproof therefore allowing them to be used in harsh conditions or wet environments.
No Glass = Less Breakage: On top of that, since LEDs contain no glass components, they are not vulnerable to vibration and breakage like conventional bulbs. LEDs are consequently better suited for use in areas like sports facilities and within areas that are prone to vandalism. LEDs typically operate at moderately low working temperatures, simplifying heat management and dissipation, which allows for the use of plastic lenses, filters, and diffusers.
Instant Lighting: When powered on, LED lights brighten up fully and instantly. This poses great advantages for infrastructure projects, such as traffic and signal lights. In addition, LED lights can be switched off and on regularly and without affecting the LED’s lifetime or light emission. On the contrary, traditional lights may take several seconds to reach their full brightness, and frequent on and off switching does radically decrease operational life expectancy.
