The cost of living has increased tremendously over the past ten years, and people are trying all possible alternatives to reduce expenses. Power bills are one of the first matters of concern. 10-20% of the electricity consumed in a house is used for lighting purposes. Of this, only a small fraction is utilized for the LED lights. A few years back, CFL's were widely installed in all places, home, and businesses for their advantage of reduced power intake. LED lights work even more efficiently than CFL's. LED is a kind of digital lighting, and they are the best kind of lighting solution available in the market currently. They are a part of a green lighting revolution with enormous energy saving capacity. Here are the top 10 reasons why LED lights can become the means for a brighter future.
10. Works even on Low Voltage
Low voltage supplies are a common issue faced by people, especially in the evening hours. Most tube lights and even CFL's fail to provide proper lighting on a low voltage day. LED lights work efficiently even at a low voltage. You can connect LED lights to a small solar panel and use it for outdoor lighting purpose. Rural areas can also benefit from LED's working on solar energy.
9. Lights up Instantly
Most traditional lights take a few seconds to power to their full brightness after it is switched on. It is a common factor among all analog lights whereby you will have to wait a few seconds to get a dark room lighted up. LED being a digital light source sparks to full-fledged lighting as soon as it is switched on.
LED's are widely used in traffic signals due to this feature. Also, the efficiency and lifespan of the lights are not affected with constant switching. The lifetime and light emission capacity of the traditional lights reduces gradually with constant on and off switching.
8. Light Dispersion
LED lights come in encapsulated form, and the shape of the encapsulation is the deciding factor for the light distribution. Several LEDs are used in an encapsulation to make it brighter and more dispersed. LED's send out focused light through the lens and using this the range of lighting can be adjusted. Factories, therefore, make use of LED's where a light for an individual machine can be focussed without causing glare issues on the efficiency of other nearby workers.
7. Reduced Cost
LED lighting system was invented by the GE engineer Nick Holonyak in 1962. The price was too high when the lights were released into the market about 30 years back. The cost has dwindled remarkably over the past three years, and they are available at very reasonable rates. Some people compare the price of LED's to halogen lamps as it has a price tag lower than LED. But they have a shorter lifespan and according to reports, the halogen lamp will have to be replaced at least every six months. On comparing cost efficiency, LED lights stand a step above all other lighting forms.
6. High Durability
LED emits light when power enters a semiconductor diode, and there are no filaments, bulbs or electrodes as it is a solid state device. The diode is in the form of a chip and is enclosed in an epoxy layer. The structure makes it highly durable and therefore they work efficiently regardless of extreme hot or cold climates. They do not break like the traditional bulbs and therefore is used in vehicles that run on harsh surfaces.
5. Various Designs
Being in the chip form, these can be arranged in any design or shape. The more the number of led lights in an arrangement, the better will be the brightness. The encapsulation of the LED light can be tinted to bring about different visibility. This flexibility factor of the LED's provides an option to produce varied lighting with classified profiles, forms, and designs. Several manufacturers are using the LED lights in various combinations to create unique lighting effects. They are available as spotlights, bayonets, chandeliers, street lights and also as led panel strip lights.
4. Environment Friendly
The most traditional fluorescent lights contain mercury, and there are several other bulbs which make use of harmful chemicals which can affect the environment adversely. Their disposal can lead to contamination. Light emitting diodes are made of recyclable materials and do not add to the toxic load of the earth.
LED's have a better life span compared to other lights, and thus, it can reduce the production, usage of resources and also the disposal of the used bulbs. Frequent replacements are not necessary, and thus, it can reduce the carbon footprint.
3. Color Options
We are used to the incandescent light color. The same effect can be produced by an LED. Earlier, filters were used on incandescent lights to achieve various colors. But it was inefficient. With LED's the range of colors that can be produced is numerous.The gallium based crystal is mixed with different materials like phosphorus to produce a range of colors using chip technologies.
2. Long Life
We are used to halogen bulbs getting fused frequently, and it's a common practice in most households to stock spare bulbs to be replaced. LED's work by diodes which has a life span of over 100,000 hours. That means you can optimally use your LED light for over 20-25 years if you use it for 8 hours daily. There is no reduction in light emission and efficiency during this time. There is no factor like burning of gases or material taking place and therefore it can give consistent brightness throughout its lifespan.
1. Energy Efficiency
LED is most acclaimed for its superior efficiency of 80-90%. By efficiency, it means that of the total power supply given to the light, only 20% is wasted as heat and the rest is optimally converted to produce light. This value, when compared to the other lights, is 60% greater.
The efficiency is directly reflected on the electricity bills. By using LED lights, you can cut down 80% of the lighting charges. This value might be a little amount when households are considered but convert to huge sums in vast areas like airports, street lights, railways, etc.
Due to the advantages of LED lights, they are widely used in various applications like aircraft industry, automobiles, electronic instruments, military and traffic. The usage is not just confined to household purposes, and the aim has been recognized to have a greener future with decreased energy consumption and product wastage.
