Deep Red LED Chips


Deep red LED chips are a specific type of LED chip that emit light in the deep red spectral range, typically between 650 and 700 nanometers (nm) in wavelength. These LED chips are made using semiconductor materials such as aluminum gallium arsenide (AlGaAs) or indium gallium aluminum phosphide (InGaAlP) that are doped with specific impurities to create a p-n junction that can emit deep red light when a voltage is applied.

Deep red LED chips are used in a variety of applications, including horticultural lighting, medical therapy, and general lighting. They are particularly useful in horticultural lighting because plants absorb light most efficiently in the deep red spectral range.

The performance of deep red LED chips is 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. The efficiency of deep red LED chips is typically lower than that of other LED chips, but they are often combined with other LED chips to create a full spectrum of light for optimal plant growth. The color quality of deep red LED chips is also important for horticultural applications, as it affects the growth and development of plants. The lifetime of deep red LED chips is influenced by the same factors as other LED chips, and proper thermal management is particularly important for maximizing their lifetime.
