LED Power Supply Modules
An LED power supply module is a kind of electronic circuit component that branches electricity from one power supply to stabilize multiple power supplies for LED lighting equipment, etc. It is installed in an AC/DC converter that converts voltage, etc. There are constant current type modules and mode switching type ones, and the light control method can be selected from analog method in which brightness is by adjusted by increasing or decreasing the amount of current supplied to an LED element and PWM method in which brightness is by adjusted by changing the ratio of the blinking time of an LED element. Since the number of outputs, input output voltage, current, power, etc. differ depending on the product, it is necessary to select an LED power supply module that is suitable for the equipment used and the application. There are products that can be used at temperatures below freezing or high temperatures and circuit-board mount type products that can be mounted on the surface of a printed circuit board, and there are few restrictions on where they can be used.
