Infrared LED 3535 is a type of infrared emitting diode that is widely used in various applications, including remote controls, surveillance systems, and consumer electronics. This article aims to provide an in-depth introduction to the infrared LED 3535 industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared LED 3535

The concept of infrared light was first discovered in the early 1800s by British astronomer William Herschel. However, it was not until the late 20th century that infrared technology became practical for commercial applications. In the 1970s, infrared emitting diodes (IREDs) were developed, and the 3535 package became one of the most popular types of IREDs due to its compact size and high efficiency.

Technology of Infrared LED 3535

Infrared LED 3535 is a surface-mount device (SMD) with a 3.5mm x 3.5mm footprint. It emits infrared light at a wavelength of around 940nm, which is invisible to the human eye. The LED is made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) material, which allows it to emit infrared light efficiently. The structure of an infrared LED 3535 typically consists of a p-n junction, a metal contact, and an epoxy lens. The p-n junction is the active region where the infrared light is generated. The metal contact provides electrical connection to the LED, while the epoxy lens focuses the emitted light into a narrow beam.
