Technology of Mini IR LED

Mini IR LED technology is based on the principles of light-emitting diodes (LEDs). LEDs are semiconductor devices that emit light when an electric current passes through them. In the case of IR LEDs, the emitted light is in the infrared spectrum, which is not visible to the human eye. The key to mini IR LED technology lies in the miniaturization of the LED package, which allows for smaller, more efficient, and higher-performance devices.

Mini IR LED packages are typically composed of a semiconductor chip, a lens, and a package substrate. The semiconductor chip is responsible for emitting the infrared light, while the lens focuses the light into a narrow beam. The package substrate provides mechanical support and electrical connections. The miniaturization of these components is achieved through advanced semiconductor manufacturing processes, such as wafer-level packaging and flip-chip technology.
