  • Recently, a demand of the digital dimmer system is increasing steadily, but domestic research is not sufficient to the expectation. In this paper, a digital dimmer equipment is developed and resented to compose a system. Digital dimmer system compose console and dimmer rack. Console controls of user interface and a total system, and dimmer rack controls brightness of lighting equipment by a way of phase angle control with each illumination level to get from console.

  • Generally, the phase control dimmer has been widely used due to simple interface and easy handling. However, the electrical characteristics are not good for the method in which the phase control dimmer cuts the input voltage. This paper has researched about DALI(Digital Addressable Lighting Interface) controller, that is the digital lighting control method, and implemented DALI protocol satisfied with the IEC-62386 standard. In addition, the existing phase control dimmer was used as the controller of DALI and not only individual control but also group control was possible. And the performance was proved to be good by applying our theory to 30[W] LED lighting control system.
