LED light has been long used as power indicator lights in consumer electronics, in bike lights, traffic signals, outdoor lighting, and in the car headlights. With the recent advancement in technology, LED light bulbs are now entering our homes as replacements for incandescent and fluorescent light bulbs.
You might be wondering how LED light bulbs work, and why are they gaining popularity? What are the benefits and drawbacks of using LED light bulbs? To find answers to such questions, stay tuned to us. Here in this article, we will discuss everything you need to know about LED light bulbs and led light supplier.
What Does LED Mean?
LED is a short form of Light Emitting Diode. LED is a semiconductor device that emits light when an electric current is passed through it. The electrons and holes are the particles that combine in a semiconductor material and produce an electric current.
How Do LED Bulbs Work?
An LED bulb produces light when an electric current passes through a semiconducting material. In this case, the semiconductor material is the diode, which emits photons by the principle of electroluminescence.
Electroluminescence is a phenomenon through which a material casts light when power is applied to it. What happens is that the electrons jump from one side (an electron-full side) to the other side (electron-deficient side) across the junction.
In simple words, we can state that when power is applied to the p-n junction, the side lacking in electrons catches electrons from the other side and fills up with the charged electrons. As an application of power, the electrons are eager to move, and during this process, light is created. That’s how an LED bulb works.
Contrarily, an incandescent bulb works when electricity is passed through a small wire or a filament. The electrical resistance of this filament causes the bulb to get hot, and as a result of this, it glows, producing light.
LED light bulbs do not rely on heat to produce light. That’s why they run cooler and are much more energy-efficient as compared to an incandescent bulb.
Do LED Light Bulbs Work in Regular Light Fixtures?
Yes, LED bulbs work in regular lighting fixtures. These include fixtures that were previously used for incandescent bulbs or CFL bulbs. However, make sure to choose an LED bulb with a base, shape, and wattage compatible with the fixture.
LED light bulbs are being manufactured in several unique designs, so you will easily find the right fit for your lamp.
Don’t get confused with the wattage. You might be thinking that you have to use an LED bulb with the same wattage as was the case for an incandescent bulb; however, that’s not true.
LED bulbs consume fewer watts than other designs to produce similar light output. For example, a 10-watt LED bulb produces the same light as a 60-watt incandescent bulb. So, by replacing old lights with modern LED bulbs, you will be going for a lower wattage.
For How Long Does an LED Bulb Last?
The lifespan of an average LED light bulb is about 25000 hours. This is much longer than an incandescent bulb, whose life span is 1000 hours while that of a CFL bulb is 10000 hours. LED light bulbs are not only energy-efficient, but they are also durable and long-lasting.
Are LED Bulbs Cost-Effective?
LED light bulbs are expensive to purchase, but they are cost-effective in the sense that they last longer and consume less energy.
What is the Color of an LED Light Bulb?
LED color temperature ranges from cool white to warm yellow; however, LED light bulbs are cooler than their counterparts.
Why Should You Use LED Light Bulbs?
The following are some of the advantages of LED light bulbs.
- LED light bulbs are energy efficient. They do not spend as much energy as an incandescent bulb does.
- These bulbs are safer as they do not contain mercury like other bulbs.
- LED light bulbs are long-lasting as they can last up to 50000 hours. Their counterparts burn out after 1000-2000 hours.
- These bulbs are dimmable, and their brightness can be adjusted using a LED-rated dimmer.
- LED bulbs fade out slowly and do not burn in a flash, which means you get ample time to find a new one.
