Bulbs are commonly used electrical devices that provide artificial light.
They come in various shapes, sizes, and types, each serving different purposes.
Understanding the basics of bulbs helps in their appropriate usage and maintenance.
Understanding their types, parts, working principle, and safety measures is crucial for their efficient and safe usage.
Incandescent Bulbs - Contains a filament made of tungsten wire.
Halogen Bulbs - combination of the halogen gas and the tungsten filament produces light with higher luminous efficacy and color temperature.
Compact Fluorescent Lamps (CFLs) - Use fluorescent technology. Emit a different quality of light compared to incandescent bulbs.
Light Emitting Diode (LED) Bulbs - Highly energy-efficient. Available in various colors and designs.
Glass Bulb - The outer covering of the bulb, typically made of glass. It protects the inner components and allows light to shine through.
Filament - A thin wire coil inside the bulb, usually made of tungsten. When electricity passes through it, the filament heats up and produces light.
Base - The bottom part of the bulb that allows it to be screwed or inserted into a socket. It contains the electrical contacts that connect the bulb to the power source.
Lead Wires - Thin wires that connect the filament to the base, allowing electricity to flow into the filament.
Inert Gas - The bulb is filled with a gas such as argon or nitrogen to prevent the filament from burning out too quickly. The gas also helps dissipate heat produced by the filament.
Support Wires - These wires hold the filament in place within the bulb and provide structural support.

Support Wires - These wires hold the filament in place within the bulb and provide structural support.

7. Working Principle When electricity passes through a bulb, it energizes the filament. This energy is converted into light, which is emitted from the bulb.

8. Uses of Bulbs Illuminating homes, offices, streets, etc. Used in various electrical appliances such as lamps, torches, headlights, etc.

9. Safety tips Don’t touch a light bulb when it’s on because it gets very hot. Turn off the switch before changing a light bulb. Ask an adult for help if a light bulb breaks.

10. Fun facts The first light bulb was invented by Thomas Edison in 1879. Light bulbs come in different colors, shapes, and sizes. Some light bulbs can change color or be controlled by a phone!
