How LED Lights Are Powered: Understanding the Basics
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
- What type of current do LED lights use? LED lights use direct current (DC) for operation.
- 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.
- What materials are LEDs made of? LEDs are made from semiconductor materials that emit light when stimulated by an electric current.
- 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.
