LED infrared transmitting tube, also known as an LED infrared LED, is a type of semiconductor light-emitting device that emits infrared light. It has become an integral part of various industries due to its compact size, low power consumption, and efficient performance. This article provides an in-depth introduction to the LED infrared transmitting tube industry, covering its history, technology, applications, market trends, and future prospects.

History and Development

The concept of the LED infrared transmitting tube dates back to the early 1960s when the first LED was invented. However, it was not until the late 1970s that the technology was developed to produce infrared LEDs. Over the years, the technology has seen significant advancements, with the introduction of different types of infrared LEDs, such as near-infrared, mid-infrared, and far-infrared LEDs. These advancements have been driven by the increasing demand for efficient and reliable infrared light sources in various applications.

Technology and Working Principle

The LED infrared transmitting tube operates based on the principle of electroluminescence. When an electric current is applied to the semiconductor material, electrons and holes recombine, releasing energy in the form of photons. In the case of infrared LEDs, these photons have wavelengths in the infrared region of the electromagnetic spectrum. The working principle involves the following steps:

• Electrical energy is supplied to the LED.
• The semiconductor material emits photons as electrons and holes recombine.
• The photons travel through the semiconductor material and are emitted as infrared light.

The key parameters of an LED infrared transmitting tube include the wavelength, intensity, and efficiency. The wavelength determines the type of infrared light emitted, while the intensity and efficiency affect the performance and application of the device.
