  • What is the function of a dimming module

    What is the function of a dimming module

    A dimming module is an electronic device that adjusts the brightness of lighting fixtures. It acts as an intermediary between the power source and the light source, controlling the amount of electrical current delivered. By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. It enables precise control over lighting intensity, enhancing energy efficiency and user comfort. Dimmer switches work well with incandescent bulbs because they provide a larger dimming option.
