Introduction to Infrared LED 3535

What is an Infrared LED 3535?

The infrared LED 3535 is a type of light-emitting diode (LED) that emits infrared radiation at a specific wavelength. These LEDs are commonly used in a variety of applications due to their compact size, low power consumption, and efficient heat dissipation. The "3535" in the name refers to the dimensions of the LED, which are typically 3.5mm in width and 3.5mm in length. This size makes them suitable for integration into compact devices such as remote controls, consumer electronics, and security systems.

How Does an Infrared LED 3535 Work?

Infrared LEDs operate on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. When a forward voltage is applied across the LED, electrons and holes recombine at the junction, releasing energy in the form of photons. In the case of infrared LEDs, these photons have wavelengths that fall within the infrared spectrum, which is not visible to the human eye. The semiconductor material used in infrared LEDs is typically a compound such as gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have band gaps that correspond to the infrared region of the electromagnetic spectrum. By carefully engineering the composition and structure of the semiconductor, manufacturers can produce LEDs that emit infrared radiation at specific wavelengths, such as 940nm or 850nm.
