In the 1970s, the first practical infrared remote controls were developed, which relied on IR LEDs to send signals to electronic devices. As the technology evolved, the 5mm IR LED became a standard component in these applications, offering a balance between size, power, and performance.

Technology of LED IR 5mm

LED IR 5mm operates based on the principle of the光电效应. When an electric current is applied to the LED, it emits infrared light at a wavelength of 5 micrometers. The key components of an LED IR 5mm include the semiconductor material, the lead frame, and the encapsulant. The semiconductor material used in LED IR 5mm is typically a compound semiconductor, such as gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to emit infrared light at the desired wavelength. The lead frame serves as the electrical connection between the semiconductor material and the external circuit. It is typically made of a metal or a metal alloy, such as copper or nickel. The encapsulant is a protective layer that surrounds the semiconductor material and lead frame. It not only protects the LED from external factors, such as moisture and dust, but also helps to optimize the emission of infrared light.
