Introduction to Infrared LED 3535

What is an Infrared LED 3535?

An infrared LED 3535, also known as an IR3535, is a type of light-emitting diode (LED) that emits infrared light at a specific wavelength. These LEDs are widely used in various applications, including remote controls, surveillance systems, and medical devices. The "3535" in the name refers to the dimensions of the LED, which are 3.5mm in width and 3.5mm in height. This compact size makes them highly versatile and suitable for integration into a wide range of electronic devices.

How Does an Infrared LED 3535 Work?

Infrared LEDs 3535 work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in these LEDs is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current is applied, electrons and holes recombine within the semiconductor, releasing energy in the form of infrared light. The emitted infrared light is typically in the near-infrared spectrum, which has a wavelength range of 700 to 1400 nanometers. This range is invisible to the human eye, making infrared LEDs ideal for applications where stealth or covert communication is required. The intensity of the emitted light can be controlled by adjusting the forward current through the LED.
