With the rapid development of technology, infrared LEDs 850 have become an indispensable part of various applications. As a high-efficiency and low-power light source, infrared LEDs 850 have been widely used in fields such as remote control, surveillance, and medical imaging. This article will introduce the industry of infrared LEDs 850, including its working principle, applications, market trends, and future development prospects.

Working Principle of Infrared LEDs 850

Infrared LEDs 850, also known as 850nm infrared LEDs, emit infrared light with a wavelength of 850nm. The working principle of infrared LEDs 850 is based on the semiconductor materials, mainly gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs). When a forward voltage is applied to the semiconductor material, electrons and holes are generated, which recombine in the semiconductor layer and emit photons with a wavelength of 850nm. The process of emitting photons is called electroluminescence. The emitted photons have a high energy level, which is why infrared LEDs 850 can be used in various applications requiring long-distance transmission and detection. The wavelength of 850nm is also suitable for passing through some materials, such as glass and plastic, which makes it more versatile in practical applications.

Applications of Infrared LEDs 850

Surveillance: Infrared LEDs 850 are used in surveillance cameras for night vision and low-light conditions. The emitted infrared light illuminates the scene, allowing the camera to capture clear images even in complete darkness. 3. Medical Imaging: Infrared LEDs 850 are used in medical imaging devices, such as endoscopes and ophthalmoscopes. The emitted infrared light can penetrate tissues and provide detailed images of internal organs and blood vessels. 4. Communication: Infrared LEDs 850 are used in wireless communication systems, such as infrared data association (IrDA) and infrared remote control. The emitted infrared light carries data or control signals, which are then received and processed by the corresponding devices. 5. Industrial Automation: Infrared LEDs 850 are used in industrial automation systems for detecting and controlling various processes. The emitted infrared light can be used to detect the presence or absence of objects, measure distances, and control the movement of machinery.
