Revolutionize Night Vision: The Power of IR LED 940 nm

Introduction to IR LED 940 nm

Background and Definition

IR LED 940 nm refers to an infrared light-emitting diode (LED) that emits light at a wavelength of 940 nanometers (nm). Infrared LEDs are a type of semiconductor device that emits light in the infrared spectrum, which is a region of the electromagnetic spectrum that is not visible to the human eye. The 940 nm wavelength is a part of the near-infrared range, which is typically used for applications that require longer wavelengths for better detection and communication.

Working Principle

IR LEDs work based on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. When an electric current is applied to the P-N junction of an IR LED, electrons and holes are created, and when they recombine, they release energy in the form of photons. The wavelength of the emitted light depends on the composition and structure of the semiconductor material.

Applications

IR LEDs 940 nm have a wide range of applications in various industries, including automotive, consumer electronics, medical, and industrial sectors. Some of the common applications include:

• Automotive: IR LEDs 940 nm are used in automotive applications for reverse parking sensors, rearview cameras, and other automotive safety features. These LEDs provide a longer detection range and better performance in low-light conditions.
• Consumer Electronics: They are used in remote controls, wireless communication devices, and other consumer electronics products for signal transmission and detection.
• Medical: IR LEDs 940 nm are used in medical applications for endoscopy, imaging, and laser therapy. They provide a longer wavelength for better tissue penetration and reduced tissue damage.
• Industrial: They are used in industrial applications for machine vision, barcode scanning, and other automation systems. These LEDs offer a longer detection range and better performance in challenging environments.
