High Brightness Light Emitting Diodes LEDs for Energy Efficient Lighting and Electronics Projects

Light-Emitting Diodes (LEDs) are semiconductor devices that emit visible or invisible light when an electric current passes through them in the forward direction. This process, called electroluminescence, occurs when electrons recombine with holes inside the semiconductor material, releasing energy in the form of light. LEDs are highly efficient, consuming very low power while producing bright illumination. They have a long operational life, fast switching speed, and excellent durability compared to traditional incandescent or fluorescent lamps. LEDs are available in many colors—such as red, green, blue, white, and infrared—depending on the semiconductor material used.
