IR LED SMD, or Infrared LED Surface Mount Device, has become an indispensable component in the field of optoelectronics. With the rapid development of the Internet of Things (IoT), smart home, and automotive industries, the demand for IR LED SMD has been increasing year by year. This article will introduce the IR LED SMD industry, including its definition, types, applications, and market trends.

Definition of IR LED SMD

IR LED SMD refers to an infrared emitting diode with a surface mount technology. It is a semiconductor device that emits infrared light when an electric current passes through it. The infrared light emitted by the IR LED SMD is invisible to the human eye, but it can be detected by various sensors and devices. Due to its small size, high brightness, and low power consumption, IR LED SMD has been widely used in various fields.

Types of IR LED SMD

IR LED SMD can be divided into several types according to different parameters, such as wavelength, color, and package form.

1. Wavelength: IR LED SMD can be divided into near-infrared (NIR) and far-infrared (FIR) according to the wavelength. NIR has a shorter wavelength, usually between 780nm and 950nm, and is commonly used in remote control, communication, and other applications. FIR has a longer wavelength, usually between 950nm and 3000nm, and is commonly used in thermal imaging, night vision, and other applications.

2. Color: IR LED SMD can be divided into red, yellow, and black according to the color. Red IR LED SMD has a higher brightness and is suitable for long-distance transmission. Yellow and black IR LED SMD have lower brightness and are suitable for short-distance transmission.

3. Package form: IR LED SMD can be divided into SMD, through-hole, and other package forms. SMD has the advantages of small size, high density, and low cost, and is widely used in the industry.
