LED bulb is a modern type of light that uses a semiconductor device to convert electrical energy into light. They are highly energy-efficient, durable, and long-lasting, using up to 75% less energy than incandescent bulbs and lasting 15 to 20 times longer. Instead of a filament, they work by passing electricity through a microchip, which illuminates the light sources, and a heat sink to dissipate heat.
Key characteristics:
• Energy-efficient: They use significantly less energy than incandescent and fluorescent bulbs.
• Long-lasting: High-quality LED bulbs can last 25,000 to 50,000 hours or more.
• Durable: LEDs are robust and have no filament to break, making them more resistant to shock.
• Versatile: They can be made in various colors and can be dimmed.
•Environmentally friendly: They contain no mercury, unlike CFLs, and are safer to dispose of.
Common applications:
• General illumination: Homes, offices, and retail stores use LED bulbs for everyday lighting in rooms, corridors, and conference halls.
• Decorative and accent lighting: They are used for highlighting features in living rooms, kitchens, and for landscape lighting.
• Task lighting: Provides focused light for specific activities, such as at a desk or in a workshop.
• Areas without natural light: Illuminating basements, garages, closets, and staircases to improve visibility and safety.
