PROBLEM TO BE SOLVED: To provide a vehicle interior lighting device capable of preventing an occupant from perceiving a difference in brightness among light source parts symmetrically arranged in a cabin.SOLUTION: Provided is a vehicle interior lighting device 5, in which a red LED 31r, a blue LED 31b and a green LED 31g in an illumination 31 and a red LED 33r, a blue LED33b and a green LED 33g in an illumination 33, symmetrically arranged in a cabin 4, are driven at the same current amount by FET 53, FET 54 and FET 55 in an output part 24, respectively. No change in color due to color illumination occurs in the horizontal direction of the cabin 4. Similarly, an illumination 41 and an illumination 43 symmetrically arranged in the cabin 4 are also driven at the same current amount by FET 56, FET 57 and FET 58 in the output part 24.SELECTED DRAWING: Figure 3

    【課題】車室内において対称に配置された光源部の輝度の差が搭乗者によって知覚されることを防止できる車室内照明装置を提供する。【解決手段】車室内照明装置5では、車室4内において左右方向に対称に配置された、イルミネーション31内の赤色のLED31r、青色のLED31b、緑色のLED31gと、イルミネーション33内の赤色のLED33r、青色のLED33b、緑色のLED33gとは、それぞれ出力部24内のFET53、54、55によって同一の電流量で駆動される。車室4の左右方向においては、カラー照明による色の変化が無くなる。同様に、車室4内において左右対称に配置されたイルミネーション41とイルミネーション43も、出力部24内のFET56、57、58によって同一の電流量で駆動される。【選択図】図3
