Revolutionizing Remote Control Tech: The Future of Infrared Patch LEDs

Introducing the world of infrared patch LEDs, a cutting-edge technology that has revolutionized the way we interact with our surroundings. These tiny, compact light sources emit infrared radiation, which is invisible to the human eye, and have found numerous applications in various industries. In this comprehensive guide, we will delve into the world of infrared patch LEDs, exploring their history, technology, applications, and future prospects.

History of Infrared Patch LEDs

The concept of infrared radiation dates back to the early 19th century when scientists began to study the spectrum of light. In the late 19th century, the discovery of infrared radiation by Sir William Herschel paved the way for the development of infrared technology. However, it was not until the 20th century that the first infrared diodes were developed, leading to the creation of infrared patch LEDs.

In the 1950s, researchers at General Electric developed the first infrared diode, which was a significant breakthrough in the field of infrared technology. Over the years, advancements in semiconductor technology have led to the development of various types of infrared diodes, including infrared patch LEDs.

Technology of Infrared Patch LEDs

Infrared patch LEDs are based on the principle of the光电效应, where an electric current is generated when light is absorbed by a semiconductor material. These LEDs consist of a semiconductor chip, a lead frame, and a lens. The semiconductor chip is made of a material that emits infrared radiation when an electric current is applied.

The lead frame is a metal frame that connects the semiconductor chip to the external circuit. The lens is used to focus the emitted infrared radiation into a specific beam pattern. Infrared patch LEDs are available in various sizes, shapes, and output powers, making them suitable for a wide range of applications.

The key parameters of an infrared patch LED include:

– Wavelength: The wavelength of the emitted infrared radiation, which can range from 780 nm to 3000 nm.
– Output power: The amount of infrared radiation emitted by the LED, measured in milliwatts (mW) or watts (W).
– Emitter size: The physical size of the semiconductor chip, which can range from 2 mm to 10 mm.
– Beam angle: The angle within which the infrared radiation is emitted, measured in degrees.
