Introduction to LED Infrared Technology

LED infrared technology refers to the use of Light Emitting Diodes (LEDs) that emit infrared light. Unlike visible light, infrared light is not visible to the human eye but is used to detect and measure various physical properties. The integration of LED infrared technology has significantly enhanced the capabilities of devices across different sectors.

History of LED Infrared Technology

The concept of using infrared light for communication and sensing dates back to the early 20th century. However, it was not until the late 1960s that the first infrared LED was developed. Since then, the technology has seen rapid advancements, with improvements in efficiency, lifespan, and cost-effectiveness.

How LED Infrared Works

LED infrared technology works by emitting infrared light through a semiconductor material. When an electric current is applied to the semiconductor, it releases photons in the infrared spectrum. These photons can then be detected by a sensor, which converts the infrared light into an electrical signal. This signal can be used to measure various parameters, such as distance, temperature, and motion.
