Infrared transmitter light emitting diode (IR LED) is a crucial component in various applications, ranging from consumer electronics to industrial automation. This article provides an in-depth introduction to the industry of infrared transmitter light emitting diodes, covering their working principles, applications, market trends, and future prospects.

Working Principles of Infrared Transmitter Light Emitting Diodes

Infrared transmitter light emitting diodes are semiconductor devices that emit infrared light when an electric current passes through them. The working principle of an IR LED is based on the quantum theory of semiconductors. When electrons and holes in a semiconductor material recombine, they release energy in the form of photons. In the case of IR LEDs, the emitted photons have a wavelength within the infrared spectrum, which is not visible to the human eye. The semiconductor material used in IR LEDs is typically a combination of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide phosphide (InGaAsP). These materials have a direct bandgap, which allows for efficient emission of infrared light. The wavelength of the emitted light can be tuned by adjusting the composition and thickness of the semiconductor layers.
