The light bulb was not invented in the year 180; rather, the development of the light bulb was a cumulative process involving many inventors over the 19th century. The earliest significant step toward electric lighting happened in 1802 when English chemist Sir Humphry Davy created an electric arc lamp by connecting two carbon rods to a battery. This was far from the modern light bulb but laid foundational work. Various inventors then developed incandescent lamps throughout the 19th century. The first practical incandescent light bulb with a carbon filament was patented by Joseph Swan in 1860, while Thomas Edison is famous for inventing the first commercially practical incandescent light bulb in 1879 and receiving a patent in 1880. Edison improved on previous work by developing a longer-lasting bamboo filament and better vacuum technology inside the bulb, making electric lighting reliable and affordable for widespread use.
So, in summary:
- No light bulb was invented around 180 or early 1800s.
- Humphry Davy in 1802 created an early electric arc lamp.
- Joseph Swan patented a practical incandescent bulb in 1860.
- Thomas Edison invented the commercially practical incandescent bulb around 1879-1880.
The invention of the light bulb was a gradual process with key contributions from multiple inventors over decades, culminating in Edison's commercial success.
