Infrared transmitter light emitting diode, commonly known as infrared LED, is an essential component in the field of infrared communication and remote control technology. This article aims to provide an in-depth introduction to the industry of infrared transmitter light emitting diodes, covering their working principles, applications, market trends, and future development prospects.
Working Principles of Infrared Transmitter Light Emitting Diode
Infrared transmitter light emitting diodes are semiconductor devices that emit infrared light when an electric current passes through them. The working principle is based on the photoelectric effect, where electrons are excited and released from the valence band to the conduction band when a forward bias voltage is applied. As the electrons move to the conduction band, they collide with lattice ions, generating infrared light in the process.
The infrared light emitted by the infrared LED has a wavelength ranging from 700nm to 1,100nm, which is outside the visible light spectrum. This characteristic makes it suitable for applications that require secure and reliable communication, such as remote control, wireless communication, and infrared sensors.
Applications of Infrared Transmitter Light Emitting Diode
1. Remote Control: Infrared LEDs are widely used in remote control devices, such as televisions, air conditioners, and projectors. The infrared signal emitted by the LED is received by the corresponding receiver, which decodes the signal and sends a command to the device to perform the desired operation.
2. Infrared Communication: Infrared communication technology is used in various applications, such as infrared data association (IrDA) and wireless infrared communication. Infrared LEDs are used to transmit data between devices, enabling secure and efficient communication.
3. Infrared Sensors: Infrared sensors use infrared LEDs to detect the presence or absence of objects, measure distances, and control access. They are widely used in security systems, automatic doors, and industrial automation.
4. Infrared Imaging: Infrared LEDs are used in infrared imaging devices, such as thermal cameras and night vision devices. These devices can capture images in low-light conditions or detect heat sources, making them valuable in various fields, including military, medical, and scientific research.
5. Infrared Barcodes: Infrared LEDs are used in barcode scanners to read the information encoded in the barcode. The emitted infrared light reflects off the barcode, and the reflected light is then detected by a sensor to decode the information.
