How Infrared Transmitter SMD Diodes Work
Infrared transmitter SMD diodes operate based on the principle of the光电效应. When an electric current passes through the diode, it emits photons, which are particles of light. These photons fall within the infrared spectrum, which ranges from 700 to 1,000 nanometers. The emitted infrared light can be used to transmit signals wirelessly, detect motion, or control devices.
The working process of an infrared transmitter SMD diode involves the following steps:
1. An electric current is applied to the diode.
2. The diode converts electrical energy into light energy.
3. The emitted infrared light travels through the air or a medium to reach the intended receiver.
4. The receiver detects the infrared light and processes the signal accordingly.
