Q1: Why do LED light strips typically use constant voltage power supplies?
LED light strips are usually composed of multiple series and parallel circuits, and integrate current-limiting resistors or driver modules internally. Using a constant voltage LED power supply facilitates the cutting, extension, and parallel connection of the light strip, and also makes on-site installation and maintenance easier, making it the mainstream solution for light strip applications.
Q1: How does the output current of a constant voltage LED power supply change?
Q2: In a constant voltage LED power supply, the output current is not a fixed value, but is determined by the load power. When the number of connected LED lights increases or their power increases, the current will increase accordingly; conversely, it will decrease. Therefore, when using a constant voltage power supply, special care must be taken not to exceed the power supply's maximum output current and power range.
