LEDs
A LED (light-emitting diode) is a small, energy-efficient light source that is commonly used in a variety of applications. LED technology has advanced significantly in recent years, making it a popular choice for a wide range of lighting needs. LEDs are known for their low power consumption, long lifespan, and ability to produce a bright, directional light. One of the primary use cases for LEDs is in general lighting, where they are used in everything from residential and commercial lighting to automotive and aviation lighting. LEDs are also commonly used in electronic displays, such as TVs, computer monitors, and smartphones, as well as in signaling and indication applications, such as traffic lights and exit signs. If you are looking for high-quality LED resources, flux.ai has the world's largest community-driven public library of LED footprints, symbols, datasheets, and simulation models.
