Difference between constant voltage light bar and constant current light bar

Constant voltage light bar is suitable for scenes that need flexible control of length, and constant current light bar is suitable for scenes that need accurate control of LED brightness. What kind of LED strip do you need to choose? Constant voltage light bar and constant current light bar are both types of LED light bars, and their difference lies in their electrical characteristics. Constant voltage light bar refers to the LED light bar with constant output voltage and variable output current according to the change of load within its working voltage range. Constant current light bar refers to the LED light bar with constant output current and variable output voltage according to the load within its working current range. Specifically, the voltage range of the constant voltage light bar is 12V or 24V, and the output current varies according to different loads. Suitable for families, businesses, hotels and other scenes that need flexible light band length. The current range of the constant current light bar is 350mA, 700mA and 1000mA, and the output voltage varies with the load. It is suitable for indoor lighting, commercial exhibition and other scenes that need accurate control of LED brightness.
