Introduction to Infrared LED 3535

What is an Infrared LED 3535?

An infrared LED 3535 is a type of light-emitting diode (LED) that emits infrared light. The "3535" refers to the dimensions of the LED, which are 3.5mm in width and 3.5mm in length. These LEDs are commonly used in various applications, including remote controls, security systems, and communication devices. Infrared light is invisible to the human eye, making it an ideal choice for applications where privacy and security are crucial.

How Does an Infrared LED 3535 Work?

An infrared LED 3535 operates on the principle of the PN junction. When a forward voltage is applied across the diode, electrons and holes are injected into the PN junction. As these electrons and holes recombine, they release energy in the form of photons. In the case of an infrared LED, these photons are in the infrared spectrum, which is not visible to the human eye. The key components of an infrared LED 3535 include the semiconductor material, a PN junction, and a lens. The semiconductor material is typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emits infrared light when excited. The PN junction is formed by doping the semiconductor material with impurities to create a region where electrons and holes can recombine. The lens is used to focus the emitted light into a narrow beam, enhancing the efficiency of the LED.
