– Longevity: They have a long lifespan, often exceeding 50,000 hours of operation.
– Wide Viewing Angle: The 5mm lens provides a wide viewing angle, allowing for better detection and communication.

Manufacturing Process

The manufacturing process of LED IR 5mm involves several steps:

1. Material Selection: High-purity gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) is used as the semiconductor material.
2. Wafer Preparation: The semiconductor material is grown on a silicon wafer using a method such as molecular beam epitaxy (MBE).
3. Structural Fabrication: The wafer is then subjected to a series of processes, including doping, diffusion, and etching, to create the p-n junction.
4. Photolithography: A mask is used to define the LED structure, which is then etched into the wafer.
5. Passivation: The surface of the wafer is coated with a passivation layer to protect the LED structure.
6. Lead Bonding: Metal leads are bonded to the p and n regions of the LED using a process such as gold wire bonding.
7. Encapsulation: The LED is encapsulated in a transparent, infrared-transmitting material such as epoxy or silicone.
8. Testing: The final product is tested for electrical and optical performance before being packaged.
