PROBLEM TO BE SOLVED: To provide a vehicle interior light device capable of alleviating potential stress caused to an occupant of a vehicle.SOLUTION: A vehicle interior light device includes an interior light (sub interior light) 2 for indirectly illuminating the vehicle interior by illuminating the vehicle interior, e.g., a ceiling panel UP, in a state in which illumination is not irradiated to a driver, and lighting control means (ECU:5) for controlling the lighting of the interior light 2. The lighting control means (ECU:5) detects stress applied to an occupant of the vehicle. For example, seat-load time, frequency and the number of times of swinging of the vehicle, temperature, humidity, etc. that are stress-causing factors are detected, and, light control is performed for changing illumination intensity, a light color, an illumination form, etc. of the illumination light of the interior light 2 based on the detected stress.
【課題】車両の乗員に生じる潜在的なストレスを緩和することが可能な車両用室内灯装置を提供する。【解決手段】運転者に対しては照明光を照射しない状態で車両の車室内、例えば天井パネルUPを照明して車室内を間接照明する室内灯(サブ室内灯)2と、当該室内灯2の点灯を制御する点灯制御手段(ECU:5)を備える。点灯制御手段(ECU:5)は車両の乗員に加わるストレスを検出する。例えば、ストレスを生じさせる要因となる乗車時間、車両の揺れ頻度や回数、温度や湿度等を検出し、検出したストレスに基づいて室内灯2の照明光の照度、光色、照明形態等を変化する調光を行う構成とする【選択図】 図2
