5V IR LED, or Infrared Light Emitting Diode, is a crucial component in various applications, particularly in the fields of security, remote control, and communication. These diodes emit infrared light at a specific wavelength, which is invisible to the human eye but detectable by IR sensors and cameras. This article delves into the industry surrounding 5V IR LEDs, exploring their technology, applications, market trends, and future prospects.

Introduction to 5V IR LED Technology

5V IR LEDs are semiconductor devices that emit light in the infrared spectrum when an electric current is applied. The '5V' refers to the forward voltage required to activate the LED, which is a standard voltage for many electronic circuits. These LEDs are compact, durable, and energy-efficient, making them ideal for a wide range of applications.

The working principle of a 5V IR LED is based on the PN junction within the diode. When the diode is forward biased, electrons from the N-type semiconductor recombine with holes from the P-type semiconductor, releasing energy in the form of photons. The wavelength of these photons determines the color of the light, with 5V IR LEDs typically emitting light in the near-infrared range (700-1000 nm).
