LED chips are small, electronic components that emit light when an electrical current is applied. These chips are typically made from a semiconductor material, such as gallium nitride (GaN) or indium gallium nitride (InGaN), which is doped with impurities to create a p-n junction. When a voltage is applied to the p-n junction, electrons and holes recombine, releasing energy in the form of light.
LED chips can produce a range of colors of light, depending on the composition of the semiconductor material and the doping impurities. For example, blue and green LEDs are typically made from GaN or InGaN, while red LEDs are made from aluminum gallium indium phosphide (AlGaInP).
LED chips are used in a wide range of applications, including lighting, displays, and indicator lights. They are often packaged into larger electronic components, such as LED modules or arrays, which can be integrated into a variety of electronic systems. The performance of LED chips is typically characterized by their efficiency, color quality, and lifetime, which are influenced by factors such as the quality of the semiconductor material, the design of the p-n junction, and the thermal management of the device.
LED technology has been rapidly developing in the recent two decades. Now LED chips can be applied in a wide range of devices from indication purposes such as traffic lights to lighting and scientific research, medical and industrial purposes. A great leap in LED efficiency and phosphor technology made a lighting revolution that helped to convert indoor and outdoor lighting from less efficient incandescent to highly efficient solid state lighting sources. We keep a large stock of LED dies of a wide variety of wavelengths and suitable for various driving currents.
