Introduction to IR Infrared LED Industry

What is an IR Infrared LED?

An IR infrared LED, short for Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current passes through it. It is widely used in various applications due to its advantages such as low power consumption, long service life, and stable performance. IR infrared LEDs have become an essential component in many industries, including consumer electronics, automotive, medical, and security systems.

Working Principle of IR Infrared LED

The working principle of an IR infrared LED is based on the photoelectric effect. When a forward voltage is applied to the PN junction of the semiconductor material, electrons and holes are generated. When the electrons and holes recombine, photons are emitted. These photons have a wavelength in the infrared range, which is not visible to the human eye. The intensity of the emitted light is determined by the material, temperature, and current passing through the LED.

Types of IR Infrared LEDs

There are several types of IR infrared LEDs, including: 1. Standard IR LEDs: These LEDs emit infrared light with a wavelength of 850nm to 940nm, which is commonly used in remote controls, IR sensors, and IR communication systems. 2. Short-wavelength IR LEDs: These LEDs emit infrared light with a shorter wavelength, typically between 780nm to 830nm. They are used in applications requiring higher sensitivity, such as barcode scanners and IR cameras. 3. Medium-wavelength IR LEDs: These LEDs emit infrared light with a wavelength between 1.3μm to 1.6μm. They are used in applications like thermal imaging and long-distance communication. 4. Long-wavelength IR LEDs: These LEDs emit infrared light with a wavelength greater than 1.6μm, such as 2.5μm to 10μm. They are used in applications like night vision and long-distance communication.
