LEDs (light-emitting diodes) are a type of light-emitting diode. It's made up of gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), and other elements. Because electrons and holes may create visible light when they recombine, they can be employed to make light-emitting diodes. It can be made up of text or digital displays and employed as indicator lights in circuits and devices. Red light is emitted by gallium arsenide diodes, green light is emitted by gallium phosphide diodes, yellow light is emitted by silicon carbide diodes, and blue light is emitted by gallium nitride diodes. It can be classified as an organic light-emitting diode (OLED) or an inorganic light-emitting diode (ILED) based on its chemical properties.
Light-emitting diodes, abbreviated as LEDs, are commonly used light-emitting devices that emit energy through the recombination of electrons and holes and are widely used in the field of lighting.
Light-emitting diodes can efficiently convert electrical energy into light energy and have a wide range of uses in modern society, such as lighting, flat panel displays, medical devices, etc. This electronic component appeared as early as 1962. In the early days, it could only emit red light with low luminosity. Later, other monochromatic versions were developed. The light that can be emitted has spread to visible light, infrared light as well as ultraviolet light, and the luminosity has also increased to a considerable luminosity. And it has also been used as indicator lights, display panels, etc. at the beginning; with the continuous advancement of technology, light-emitting diodes have been widely used in displays and lighting.
