Yellow, amber, and orange LED chips are a type of LED chip that emit light in the yellow, amber, or orange spectral ranges. These LED chips are typically made from semiconductor materials such as aluminum gallium indium phosphide (AlGaInP) or gallium arsenide phosphide (GaAsP) that are doped with specific impurities to produce the desired color.
Yellow LED chips emit light in a range of wavelengths between green and red, typically around 585 nanometers (nm). They are used in a variety of applications, including traffic signals, automotive lighting, and general lighting.
Amber LED chips emit light in the yellow-orange spectral range, typically around 590 nanometers (nm). They are often used in automotive lighting, signage, and backlighting for displays.
Orange LED chips emit light in the orange spectral range, typically around 605 nanometers (nm). They are used in applications such as automotive lighting, signage, and specialty lighting.
The performance of yellow, amber, and orange 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.
