In proportion to the development of various cultural contents industry. although the lighting tools with advanced control system are needed. the fields of the lighting tools are not competitive in techniques because they are limited in small businesses and have been lost their markets to foreign companies in the high value added industry. Accordingly, the technique that is better than current lighting tools is needed urgently. So, for the new lighting tools, this paper presents a new dimming method using IGBT(Insulated Gate Bipolar Transistor) devices. There are three procedures in this study. For the first, the author verify superiority of IGBT Dimmer with simulation using EMTDC former step for development of IGBT Dimmer. Secondly, the author made IGBT Dimmer directly with the basis of simulation results. For the last, efficiency, THD(Total Harmonic Distortion) current, temperature characteristic, noise characteristic, voltage drop, heat losses between the IGBT Dimmer and the Thyristor Dimmer that is being used popularly in the stages and the theaters were tested and compared.
