Introduction to Infrared LED 3535: An Insight into the Industry

What is an Infrared LED 3535?

An infrared LED 3535 is a type of light-emitting diode (LED) that emits infrared light. It is characterized by its size, which is 3.5mm x 3.5mm, hence the name "3535". These LEDs are commonly used in various applications, such as remote controls, barcode scanners, and surveillance systems. They offer several advantages over traditional infrared devices, including a smaller size, higher efficiency, and longer lifespan.

How Does an Infrared LED 3535 Work?

An infrared LED 3535 operates on the principle of semiconductor physics. When a current is applied to the diode, it emits infrared light. The light is generated through the recombination of electrons and holes within the semiconductor material. The infrared light produced is typically in the range of 780nm to 950nm, which is outside the visible spectrum. The key components of an infrared LED 3535 include the semiconductor material, the encapsulant, and the lead frame. The semiconductor material is typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emits infrared light when excited. The encapsulant is used to protect the semiconductor material from environmental factors, such as moisture and dust. The lead frame provides electrical connections to the semiconductor material.
