LED Lamp And Power Supply Used In Engineering

LED lamp and power supply used in Engineering

1. What is a constant voltage power supply

Refers to the input voltage within the specified range, the load current changes within the rated range, the output voltage remains constant.

2. What is a constant current power supply

Refers to the input voltage within the specified range, the output current is constant, and the output voltage varies with the size of the load in a certain range.

3. Under what conditions do we choose constant voltage power supply and under what conditions do we choose constant current power supply?

A, the constant voltage power supply and constant current power supply can be used in the places where the light is always used. The relative luminance uniformity of the constant current power supply is better than that of the constant voltage power supply.

B, used in the place of gradual change and scanning, it is more suitable to use constant voltage power supply.
