1. Incandescent light bulbs: These work by heating a filament inside the bulb, causing it to give off light.
2. Fluorescent tubes: These contain gas or vapor that emits ultraviolet light when electricity is applied. The ultraviolet light causes a phosphorescent coating on the inside of the tube to give off visible light.
3. Light emitting diodes (LEDs): These are small semiconductors that convert electrical energy into light. LEDs are commonly found in electronic devices such as televisions and computer screens, as well as in outdoor lighting and automotive headlights.
