Introduction to LED IR Technology
LED IR technology involves the use of light-emitting diodes (LEDs) to emit infrared light. Unlike visible light, infrared light is not visible to the human eye, making it ideal for various applications where privacy and security are paramount. The primary advantage of LED IR technology is its ability to provide a compact, energy-efficient, and cost-effective solution for infrared illumination.
How LED IR Works
LED IR technology operates on the principle of photoelectric conversion. When an electric current passes through a semiconductor material, it emits light in the infrared spectrum. This process is known as electroluminescence. LED IR devices typically consist of a semiconductor material, such as gallium arsenide (GaAs), and a reflector to concentrate the emitted infrared light in a specific direction.
