Your average incandescent light is a basic idea; an electric current is carried through a thin wire called the filament, and through that filament heat begins to collect until there’s enough of a glow that today we refer to as turning on a light.
It’s something a lot of us take for granted, especially when we have power outages and have to think about how many appliances and electronics actually use power.
In some ways, today’s societies are moving towards how to utilize energy without having to use so much power and have such a high energy bill each month. The LED light is one of those concepts and just improved upon what was already there: the traditional light bulb. But what makes LED bulbs better?
The History of the LED Light
First, we need to go back to the invention of the light bulb by Thomas Edison. Although it’s debated who was actually the first person to invent light, Edison and his associates worked on over 3,000 different ideas in the late 1800s to develop what we now know as the incandescent light bulb.
This paved the way for electricity as we know it and how we can harness electricity to power certain objects, such as the LED light.
The LED light bulb wasn’t invented for another 100 years after the original light bulb, but it improved upon what was already there. Instead of a filament, the LED light utilized a diode to emit light, which was much more efficient and used a lot less energy. If a diode isn’t a familiar term, a diode is a component that controls the direction of a current in a circuit.
Just like how the filament controlled where the electricity flowed to make light, a diode can encourage direction. It can also emit more light.
Why Are LED Lights Better?
Now, why are LED lights much better than traditional, filament bulbs? The first thing is the cost of energy consumed. Look on the back of any box containing an LED bulb. It’ll tell you how much energy you save by switching to LED lights. But to say it simply, LED lights use more than 75% less energy than that of traditional bulbs.
They also last a lot longer, too. Up to 95% of the energy used in LED bulbs is converted into light, while only 5% is wasted as heat. Compare that to the ordinary light bulb; 90% of its energy is wasted as heat while only 10% of its energy is used to produce light.
Less energy used reduces how much energy you take from the power plants to power the lights in your home and it decreases gas emissions.
LED Lights and Heat
One thing to be wary of with LED lights is that you cannot use them in enclosed fixtures that allow them to overheat or don’t encourage proper ventilation. Thus, decreasing the overall lifetime use of your bulb significantly.
LED lights are very sensitive to heat because of all the components inside, which change the high voltage electricity to that of lower voltage. Other than that, LED bulbs are cool to the touch, unlike traditional light bulbs.
If you have the resources to make the switch, it’ll save you money in the long run if you switch to LED lights. There’s less cost when it comes to your electrical bill each month, less heat being wasted, and it’s better for the environment.
You’ll even find most companies, such as hotels, have switched to LED lights where they can. And if big corporations see LED light bulbs as a way to cut costs, then you should too.
