LED infrared transmitting tube, also known as an LED infrared LED, is a crucial component in various applications, particularly in the fields of remote control, surveillance, and wireless communication. This article delves into the industry of LED infrared transmitting tubes, exploring their history, technology, applications, market trends, and future prospects.

History and Development

The concept of using light for communication dates back to ancient times, but it was not until the 20th century that infrared technology began to gain traction. The first practical infrared transmitting devices were developed in the 1930s, primarily for military applications. Over the years, advancements in semiconductor technology led to the invention of the LED, which revolutionized the infrared transmitting tube industry.

LED infrared transmitting tubes were first introduced in the 1960s. Initially, they were used in simple applications such as remote controls for televisions and audio equipment. However, with the advancement of technology, their applications expanded to include industrial automation, medical devices, and security systems.

Technology and Working Principle

LED infrared transmitting tubes are based on the principle of emitting infrared light through a semiconductor diode. When a forward voltage is applied across the diode, electrons and holes recombine, releasing energy in the form of photons. These photons fall within the infrared spectrum, which is not visible to the human eye.

The key components of an LED infrared transmitting tube include a semiconductor chip, a lens, and a housing. The semiconductor chip is made of gallium arsenide (GaAs) or gallium nitride (GaN), which emits infrared light when an electric current is applied. The lens focuses the light into a narrow beam, enhancing the range and directionality of the transmission. The housing protects the internal components and ensures proper alignment.
