Wide Angle IR LED: A Comprehensive Industry Overview

Introduction to Wide Angle IR LED

The wide angle IR LED, or Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light. These LEDs are widely used in various applications, such as security systems, remote controls, and surveillance cameras. With the continuous development of technology, the demand for wide angle IR LEDs has been growing rapidly in recent years. This article aims to provide a comprehensive overview of the wide angle IR LED industry, covering its definition, working principle, applications, market trends, and future prospects.

Definition and Working Principle of Wide Angle IR LED

A wide angle IR LED is a semiconductor device that emits infrared light with a wide angle. It consists of a p-n junction, where the p-type and n-type semiconductor materials are combined to create an electric field. When a forward bias voltage is applied, electrons and holes are injected into the depletion region, and through the process of recombination, infrared light is emitted. The working principle of a wide angle IR LED is based on the quantum efficiency of the semiconductor material. Different materials have different emission wavelengths, which can be adjusted by changing the composition of the semiconductor material. For example, a gallium arsenide (GaAs) wide angle IR LED can emit light with a wavelength of 850nm, while a silicon carbide (SiC) wide angle IR LED can emit light with a wavelength of 940nm.
