Light-emitting Diodes

Light-emitting diodes (LEDs) are semiconductor devices that emit light when an electric current is passed through them. LEDs are widely used in space and astronautical engineering due to their high efficiency, low power consumption, and long lifespan. They are used in spacecraft for various applications such as lighting, communication, and sensing. LEDs are also used in space suits to provide illumination for astronauts during spacewalks. In addition, LEDs are used in satellite communication systems to transmit data between ground stations and satellites. The use of LEDs in space and astronautical engineering has significantly reduced the power consumption of spacecraft and increased their reliability.
