Red LED Chips


Red LED chips are a type of LED chip that emit light in the red spectral range, which is between 620 and 750 nanometers (nm) in wavelength. These LED chips are made using semiconductor materials such as aluminum gallium indium phosphide (AlGaInP) or gallium arsenide phosphide (GaAsP) that are doped with specific impurities to create a p-n junction that can emit red light when a voltage is applied.

Red LED chips are used in a variety of applications, including automotive lighting, traffic signals, backlighting for displays, and general lighting. They are also used in combination with green and blue LED chips to create full-color displays and lighting.

Red LED chips offer several advantages over traditional lighting sources, including lower power consumption, longer lifetime, and higher color quality. They also do not contain hazardous materials, such as mercury, which is found in many traditional lighting sources.

The performance of red 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.
