The LED Smart Light Bulb that you use today was not present in the past.
In fact, the technology has been evolving since the invention of the first light bulb in the 18th century to reach the current form of the LED light bulbs.
Countless people have played their role in order to make modern-day light bulbs.
In this blog post, we will walk you through different types of light bulbs that have been previously used in order to enlighten the history of light bulbs.
Enough talking, let’s check out the evolution of the light bulbs.
The Historical Evolution of Light Bulb Over the Years
From the wood fires to the Alexa smart light bulbs, technology has evolved extensively. We will discuss the first light bulb in history, the Arc Lamp, and the most modern LED light bulbs, and everything that comes in-between.
So, let’s get started.
The Carbon Arc Lamp, which is also regarded as the first artificial light source was first discovered by an English scientist, named Humphry Davy.
It was the first-ever artificial light demonstration, which ultimately paved the way for other scientists.
The Arc Lamp was invented by Humphry Davy, he demonstrated light spread over 4-inches by using charcoal rods, and a battery.
The rods of the arc-lamped have to be vaporized at a very high-temperature (~3600C), in order to start the ionization process.
This ionization process takes place between the carbon ions, and the air ions to produce electric light.
Although, the Carbon Arc Lamps have been used extensively in the 19th century, and had marginally good light. There were numerous cons related to the Carbon Arc Lamps.
- The color of the Arc Lamp depends upon the time, temperature, and surrounding weather. Thus, a constant color of the light cannot be maintained.
- Arc Lamps produced very dim light.
- Carbon Arc Lamps produce Carbon Mono-oxide (CO) gas, which is a health hazard and can cause suffocation in a closed environment.
- The lifespan of Carbon Rods was very low. To be more precise, the best of the best rods lasted for 75-hours, and a specialized person was required to replace the bulbs.
- Due to the ionization between the air, and the carbon, a constant buzzing sound is produced, which is very disturbing.
Incandescent Light Bulb
The Incandescent Light Bulbs were certainly a major improvement over the Arc Lamps as they were more versatile, affordable, and offered better lighting performance.
Thomas Edison is often regarded as the founder of the Incandescent light bulb, as he was the first person to commercialize the electric light bulbs.
There are numerous theories about the original inventor of the incandescent light bulb.(You can check out the role of different scientists in the invention of the light bulb also).
The incandescent light bulb uses a filament with a base. When an electric current is passed through this filament, its temperature raises, and as a result of high-temperature, it glows.
The working of the incandescent light bulb produces a huge amount of heat. Almost 90% of the electrical energy is lost in the form of heat, and the rest of the energy is used for light.
There have been a bunch of different substances used in the incandescent light bulb as a filament.
Tungsten is the most reliable and used filament in light bulbs.
More interestingly, the incandescent bulb was the first-ever commercially produced light bulb.
With the passage of time, in order to increase the lifespan of the incandescent light bulb filament, an inert gas enclosed in a glass jar was used.
Although the incandescent light bulb was a major leap over the carbon arc lamp, as it offered better lightning performance, and lifespan.
Still, it has a much lower lifespan than a lot of modern-day light bulbs.
Incandescent bulbs offered up to 1000-hours of runtime, which was absolutely amazing back in time.
The Halogen Bulb is an enhanced, and technologically advanced version of an Incandescent light bulb. It works the same as an incandescent light bulb, but with a twist.
There is an inert gas enclosed inside the vacuum, in order to enhance the lifespan of the filament.
The first-ever patent of halogen light bulbs was registered back in 1892, and Europe phased-out all the halogen light bulbs in 2009.
The usage of inert gas, such as Iodine, or chlorine increases the lifespan of the tungsten filament.
Moreover, it also improves the color temperature and brightness of the light.
Here are the pros of a halogen bulb over an incandescent bulb.
- Halogen bulbs have a much higher lifespan as compared to incandescent light bulbs.
- They offer a brighter, and better light, that is easier on the eyes.
- These bulbs do not get darker over time, as is the case with incandescent bulbs.
- Halogen bulbs do not get as hot as incandescent bulbs, which makes them safer in handling.
- Lastly, these bulbs are a little bit more economical when compared to the prior type of light bulbs.
CFLs were introduced as a replacement for the Halogen bulbs. These bulbs are very energy-efficient as compared to the prior generation of electric bulbs.
There is a bent tube, with the contaminants of Argon, and vapors of mercury used in these types of bulbs.
When electricity is passed through this bent tube, it produces a glow of light.
The tube of these bulbs is coated with fluorescent, which results in extra bright lightning.
In addition, the color of the CFLs can also be changed by using color coating on the glass tube.
More Importantly, these bulbs are very much weather-resistant and do not get easily heated like incandescent or halogen bulbs.
Lastly, these bulbs can be dimmed by using a dimmer switch.
LED Light Bulbs
The LED or light-emitting diode bulbs are the latest types of electric bulbs available in the market. These bulbs offer superior lighting performance.
LED light bulbs are twice as bright as the CFLs light bulbs of similar wattage. In addition, the LED light bulbs offer superior daylight performance, with excellent battery life.
Electric light bulbs have extensively evolved since the invention of the first light bulb. We have elaborated on the different phases of the electric light bulb, and the evolution of the light bulb.
