LEDs get plenti advantages pass incandescent light sources like say dem dey use less energy, last longer, strong well well, small size, and quick to switch on and off. People dey use light-emitting diodes for different things like aviation lighting, car headlamps, adverts, general lighting, traffic signals, camera flashes, and lighted wallpaper. As of 2015, LEDs wey dey powerful enough for room lighting still dey cost more and need precise current and heat management pass compact fluorescent lamp wey get the same output.

Electroluminescence as a thing wey dey shine light was discovered for 1907 by British person H. J. Round of Marconi Labs, using silicon carbide crystal and cat's-whisker detector. Soviet inventor Oleg Losev talk say he create the first LED for 1927. Him research dey spread for Soviet, German, and British scientific journals, but dem no use the discovery for many years. Kurt Lehovec, Carl Accardo, and Edward Jamgochian explain the first light-emitting diodes for 1951 using SiC crystals with current source from battery or pulse generator and compare am to pure crystal for 1953.
