Overview of LEDs
Light Emitting Diodes (LEDs) are semiconductor devices that emit light when an electric current passes through them. Unlike traditional incandescent bulbs, LEDs don't have a filament that burns out; instead, they are illuminated solely by the movement of electrons in a semiconductor material, typically gallium arsenide or gallium phosphide. The efficiency of LEDs comes from their ability to convert a high percentage of electrical energy into light, with minimal heat production compared to older lighting technologies. This makes LEDs more energy-efficient, durable, and longer-lasting. LEDs are designed to offer a wide range of colors, brightness levels, and light intensities, making them versatile for various applications. For example, they are used in residential lighting for energy savings and longevity, in electronic devices as indicators and backlighting, in automotive lighting for headlights and signal lights, and in street lighting for improved visibility and reduced maintenance.
