Learn how LED lights work, including the role of direct current and drivers in powering them efficiently.

517 views

LED lights are powered by applying a direct current (DC) voltage across their terminals. They contain a semiconductor material that emits light when an electric current passes through it. It is essential to use drivers or power supplies to provide a consistent voltage and protect the LED from potential damage due to fluctuations.

FAQs & Answers

  1. What type of current do LED lights use? LED lights use direct current (DC) for operation.
  2. Why do LED lights need a power supply? A power supply is essential to maintain consistent voltage and prevent damage to the LEDs from fluctuations.
  3. What materials are LEDs made of? LEDs are made from semiconductor materials that emit light when stimulated by an electric current.
  4. Can LEDs operate on AC power? LEDs generally require a DC voltage; however, some LEDs can be configured to work with AC power using drivers.
