10mm IR LED, or Infrared Light Emitting Diode, is a compact and highly efficient component that has found widespread applications in various industries. These LEDs emit infrared light, which is invisible to the human eye but can be detected by sensors and cameras. This article delves into the details of 10mm IR LEDs, their working principles, applications, and the future trends in the industry.
Introduction to 10mm IR LED
The 10mm IR LED is a type of semiconductor device that emits infrared light when an electric current is applied to it. The size of the LED is determined by the dimensions of its package, which in this case is 10mm in diameter. The small size makes it highly suitable for integration into compact devices and systems where space is limited.
Working Principles of 10mm IR LED
10mm IR LEDs work on the principle of electroluminescence. When an electric current is passed through the diode, it excites the electrons within the semiconductor material, causing them to recombine with electron holes. During this process, the excess energy is released in the form of photons, which are infrared light in the case of IR LEDs.
The semiconductor material used in 10mm IR LEDs is typically a combination of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to efficiently emit infrared light at specific wavelengths, usually between 780nm and 950nm.
