Traditional light bulbs have been in use in lightning our houses since the 1800s. However, nowadays, they have become inefficient as they consume a lot more energy as heat and are avoided owing to their financial and ecological concerns.
LED lighting has long been used as power indicators in electronics such as in bike lights, in cars, for outdoor lighting, in traffic lights, and so on. With advancements in technology, these LED lights have now reached our homes as a replacement for incandescent and fluorescent bulbs.
Let’s explore why have these bulbs gained a significant reputation as there are many led lights manufacturers and how does an LED bulb work.
What is an LED?
LED is an acronym of “Light Emitting Diode,” a type of semiconductor that fits in an electronic circuit and carries electric current in one direction.
How Does a LED Bulb Work?
An LED bulb works when an electric current is passed through a semiconducting material. This semiconductor material, in turn, emits photons (light) and produces light by the principle of electroluminescence.
In simple words, an LED produces light when electrons move around in its semiconductor structure.
LED is something that is named “solid-state lightning technology” or SSL. What happens is, instead of emitting light from a vacuum or a gas, an SSL emits light from a piece of solid matter. In the case of LED, this piece of matter is a semiconductor.
What is A Semiconductor?
A semiconductor is a substance that can conduct electrical current. LEDs use indium-gallium-nitride (InGaN) as their conducting material.It is made of positively and negatively charged components.
The positive side consists of holes, whereas the negative side has free electrons floating around it.When an electric charge strikes the semiconductor, the electrons start to flow from the negative layer to the positive layer. These excited electrons emit light as they move into the positively charged holes.
Contrarily, an incandescent bulb works when electricity passes through a small wire or a filament. This electrical resistance of the filament causes it to get hot, due to which it glows and produces light.
The best thing about LED is that it does not rely on heat to produce light, which means it runs cooler and is much more efficient than an incandescent light bulb.
Are LED Bulbs Good to Light Homes?
The problem in using LEDs as a primary home lightning source is that they emit a lot of light. Due to the unique structure of an LED, some of that light gets trapped inside. That’s why an LED bulb is generally dimmer than an incandescent bulb. So, if you want bright light, consider using fluorescent bulbs.
However, you can now find brightened LED bulbs as well. LED replacement bulbs are available that emit light equivalent to a 60-watt incandescent light bulb. This advancement in LED bulbs makes them a viable technology for fulfilling lighting needs at home.
Benefits of LED Bulbs
You might not find LED bulbs in most houses; however, there are some good reasons to use them in homes. Let’s discuss them.
LED Bulbs are Energy Efficient
LED bulbs are energy efficient, which means they reduce energy consumption. LED bulbs use photons to produce light in contrast to fluorescent bulbs, which work on the principle of heat energy. Hence, LED bulbs consume less power and are energy efficient.
LED Bulbs are Safer
LED bulbs are much safer because they do not contain mercury like other fluorescent lamps or CFLs.
LED Bulbs Last Longer
LED bulbs last much longer than traditional fluorescent bulbs. They may last for 50000 hours, whereas conventional bulbs last for 1000 to 2000 hours.
LED Bulbs are Dimmable
These bulbs are dimmable. LED bulbs can be adjusted with LED-rated dimmers to enhance the lighting of your space.
LED technology is taking over the lighting world. LED bulbs have gained a significant reputation in the recent past. These bulbs provide a cost-effective and energy-efficient lighting solution for your homes. Along with lowering the utility bills, these bulbs also take care of the issue of the non-renewable energy source.
So, it’s time to get rid of traditional fluorescent bulbs and replace them with energy-efficient LED bulbs.
