LEDs require very little power. Most LEDs result in a 60-75% improvement in the overall efficiency of the facility's lighting. Depending on the LEDs the savings could also be more than 90%
The led device is extremely small. The size can be less than a 10th of a single mm2 with the largest one can also be as small as mm2. This makes them extremely adaptable to large no. of light applications.
This is one of the most significant advantages of LED its lifespan compared to other conventional bulbs. It also has a very low maintenance cost and very low-cost replacement parts. An average LED bulb can last for more than 50,000 operational to 100,000 operating hours. This is 40 times more than a conventional bulb.
LEDs have very low recycling costs. The no. 1 hazard when it comes to lighting is heat emission. LEDs do not emit any forward heat as compared to fluorescent or conventional bulbs. They also function on low power and can also function on very low voltage. They are very safe compared to other bulbs.
LEDs are solid-state lights. This means the glass covering the conventional bulb uses is not required. Thus, they are much easier to use.
LED emits light in only 180 degrees whereas every other light emits light in a 360-degree direction. This might seem like a drawback but 360-degree emissions need necessary objects to deflect upon to keep the room light up. This increases the cost of the device and makes it less efficient whereas LED completely solves this problem and gives the user a lot of savings on electricity.
LEDs are recyclable and the recycling charges are also very low.
These are some of the various types of LEDs:
Known as red green blue LEDs they are 3 LEDs in one. You can control the intensity of each color. This type of LED has a 4 pin one for each color and a common pin. Common pin is the anode and others are the cathodes.
There are some types of LEDs that come with a built-in resistor and also a small current resistor.
They are not a type of LED but called a package. As LEDs have become smaller and smaller, manufacturers have figured out to cram more components in them. SMD is a smaller version of the standard parts that are available. SMD LEDs come in various sizes from very small to very large.
These types of LEDs are very bright. An LED is considered high power if it can disband 1watt or more power. These are very high-quality LEDs found in very fancy lights. These types of LEDs can also be used as headlights in vehicles as they are so bright. LEDs of this kind sometimes require a heatsink. They sometimes release so much heat that the LED can damage itself if they don't have a proper cooling system.
Some LEDs emit light outside the visible spectrum. Such types of LEDs are used in a TV remote to send signals between the remote and the setup box. Sending small pieces of information in the form of invisible light.
The above article summarizes every piece of information related to LEDs. This article takes your What is LED, what is its full form, benefits of using an LED, how does LED work, and what are the various types of LEDs.
