A light-emitting diode (in short: LED) is a light source made of semiconductor materials that emits light when an electric current passes through it.
Bulbs are considered the most economical light bulbs in terms of their consumption of electricity. For example, if the power of a regular bulb that works with a tungsten filament has a power of 25 watts, a bulb from the bulb compensates for it with a power of only 4-5 watts, even though each one of them produces a light intensity of 190 lumens.
Its development dates back to the 1960s when semiconductors were discovered. In the beginning, it emits one weak light, but over time it was possible to develop it to emit the three basic colors: red, blue, and green. It is often used in large, luminous paintings and others. It now has a large capacity to emit bright light with very little electricity consumption.
LED lights are energy efficient because the luminous efficiency of the LED is good. Luminous efficiency is expressed as the brightness (luminous flux) per power consumption of the lighting, and the unit is lm/W (lumens per watt).
The higher the number, the better the efficiency, that is, the energy saving.
The luminous efficiency of a candle is about 0.3 lm/W, a 40W incandescent bulb is about 12 lm/W, and a fluorescent lamp is 40–110 lm/W. The luminous efficiency of the white LEDs used in LED lighting was originally around 20 lm/W, but recently more energy-saving models with over 200 lm/W have been produced.
However, the above figures are the efficiency of the lamp part only and do not include the loss caused by the ballast required for fluorescent lamps and discharge lamps and the constant current drive circuit required for LEDs.
The luminous efficiency of LED lighting fixtures, which includes these losses, is rapidly improving compared to conventional lighting fixtures due to the development and improvement of various
materials, including LEDs, and the competition among lighting manufacturers
LED light bulbs save the most energy out of any commercially available type today. Not only do they use 90% less power than incandescent bulbs, but they can also last 25 times longer, reducing the cost of replacement.
LED lights save money because of their long life, LED light sources last longer, avoiding the hassle of frequent changing of light bulbs. This significantly reduces waste but also saves money in the long term, This significantly reduces waste but also saves money in the long term.
The lifetime of a LED light source can be up to 10 times longer than that of traditional light sources. A conventional bulb has a lifetime of about 2.000 hours, while Philips LED lighting has a lifetime up to 20.000 hours. That is the equivalent of 20 years!
In addition When you switch to energy-efficient lighting, you can light your home using the same amount of light for less money. Lighting accounts for around 15% of an average home's electricity use, and the average household saves about $225 in energy costs per year by using LED lighting. if you are still using incandescent light bulbs, switching to energy-efficient lighting is one of the fastest ways to cut your energy bills. For high-quality products with the greatest energy savings.
Smart lights always work with LED lighting. This is a lot more energy-efficient than a classic energy-saving light or halogen lighting. Imagine you have 10 halogen spot lights in your house You can save € 50 annually on average by replacing them with LED smart lights.
It should also be noted Since LED lights use 90% less power than incandescent bulbs, your electric bill should go down by making the switch. CFLs are good, but their savings on traditional light bulbs is only 25% to 35% in electrical usage.
In addition to saving money and energy, LED lights have many advantages
•Environmentally Friendly
LED lighting does not use harmful substances such as mercury or lead. Also, as described in “Comparing electricity bills,” you can reduce power consumption (= energy saving). In other words, the amount of CO2 emissions can be reduced, reducing the burden on the environment. In addition, it can be said that it is environmentally friendly in terms of waste reduction because it has a long life.
• UV-free (pest free)
Fluorescent lights contain 1/1000th of the UV light of sunlight. There are two types of LEDs, one that emits almost no ultraviolet rays and one that contains ultraviolet rays.
In addition, pests have the characteristic of coming close to ultraviolet rays. One of the merits is that pests do not come by UV-free.
•Good responsiveness
The flashing response speed of LEDs is said to be about 1000 times faster than that of incandescent bulbs. In other words, it will turn on instantly when it is energized, so it will have many advantages in places where there are many on and off, such as in the workplace
