History and background of light bulbs
The history of light bulbs can be traced back to the 18th century when people used candles and kerosene lamps. In 1879, American inventor Thomas Edison successfully developed the first commercially viable light bulb, marking the beginning of modern lighting.
Emergence and development of LED lights
LED lights were first invented by Nick Holonyak in 1962. However, for decades, the application of LED lights was limited due to their narrow spectrum, low brightness, and high cost. But with the advancement of technology and the decrease in cost, LED lights have become one of the most popular lighting solutions.
Invention and Development of 
Predecessor of Light Bulbs
The predecessor of light bulbs was arc lamps, which used two electrodes to produce arcs in the air, creating intense light. However, arc lamps required high voltage and current and were soon found to be dangerous.
The first successful light bulb experiment
In 1879, Edison used a carbon filament as the filament, placed it in a vacuum glass bulb, and heated it to make it glow. This was the first successful light bulb experiment.
The first commercial light bulb
In 1880, Edison developed the first commercial light bulb, using a more durable filament and adding some inert gas to extend the life of the bulb.
Development history of light bulbs
Since Edison invented the first light bulb, the design and manufacturing of light bulbs have continued to evolve. The material of the filament has been continuously updated, from carbon filament to tungsten filament to various metal alloys used today. The structure and manufacturing process of light bulbs have also been continuously optimized and improved.
The Importance of Light Bulbs

FAQ
When and where was the light bulb invented?
A：The light bulb was invented in the late 19th century, with the first commercially successful bulb being developed by Thomas Edison in the United States in 1879.
Where is the first light bulb?
A: Thomas Edison developed the first light bulb in his Menlo Park, New Jersey laboratory.
Who invented the light bulb first?
A: The invention of the light bulb is attributed to several inventors, including Joseph Swan, Hiram Maxim, and Thomas Edison. However, Thomas Edison is often credited with inventing the first commercially successful light bulb.
Where does the bulb light come from?
A: The light in a bulb comes from the filament, which is heated by an electric current and emits light.
Why is it called a bulb?
A: The name “bulb” comes from the bulbous shape of the glass enclosure that contains the filament and other components of the light bulb.
