Study Notes
Early Light Bulb Development
- Humphry Davy created the first incandescent electric light in 1800.
- English physicists in 1860 focused on developing a practical and long-lasting electric light.
- Thomas Edison experimented with numerous filaments in 1879 to find the ideal material for a glowing and durable bulb.
Key Inventors and Innovations
- Joseph Swan (1848-1928) improved upon the light bulb by inventing a carbon filament, patented in 1881. Swan also worked with Edison's research team.
- In 1903, William David Coolidge invented a treatment for the filament, improving its durability.
- William David Coolidge also invented a tungsten filament, which lasted longer than previously used filaments.
Light Bulb Components
- Filament: Metal wires that glow brightly when electricity flows through them.
- Leads: Wires that carry electricity from the bulb's electrical contact to the filament.
- Base: The metallic base of the bulb that connects with the lamp's electrical contacts.
- Stem: The glass part that insulates the bulb's fuses.
- Bulb: The glass enclosure filled with inert, non-reactive gases.
- Screw Cap: The threaded base of the bulb that secures it to a lamp.
- Supports: Wires that physically hold the filament in place.
