DIMMER AND LIGHTING SYSTEM

To provide a dimmer 1 which has a size suitable for an application of dimming a luminaire 200 for a household, and capable of separately controlling a dimming level for the luminaire 200 of two systems, and controlling the luminaire 200 of each system 200A and 200B to the same dimming level by an extremely easy operation.SOLUTION: A dimmer includes: a first dimming control circuit which generates a dimming control signal for controlling a dimming level of a luminaire 200 in accordance with an operation of a first dimming operation means; and a second dimming control circuit which generates a dimming control signal for controlling a dimming level of the luminaire 200 in accordance with an operation of a second dimming operation means. The first and second dimming operation means are each configured from a biaxial and twin variable resistor 50, and first and second operation knobs 70,80 each mounted on two rotation shafts included in the variable resistor.SELECTED DRAWING: Figure 2 【課題】 家庭用の照明器具２００を調光する用途にも好適な大きさであって、２系統の照明器具２００に対して調光レベルを別々に制御することができ、しかも各系統２００Ａ，２００Ｂの照明器具２００を極めて容易な操作で同じ調光レベルに制御することもできる調光器１を提供する。【解決手段】 第１の調光操作手段の操作に応じて照明器具２００の調光レベルを制御する調光制御信号を発生させる第１の調光制御回路と、第２の調光操作手段の操作に応じて照明器具２００の調光レベルを制御する調光制御信号を発生させる第２の調光制御回路とを備える。第１，第２の各調光操作手段は、２軸２連型可変抵抗器５０と、この可変抵抗器が備える２本の回転軸にそれぞれ装着した第１，第２の各操作つまみ７０，８０で構成してある。【選択図】 図２
