To provide a room lamp for vehicles effective in preventing an occupant from getting motion sickness due to reading or the like.SOLUTION: A room lamp system has a control unit 2 (lamp ECU) including vibration detection means 4 that detects a vibration occurring in a vehicle, and lighting control means 5 that controls lighting of a room lamp 1 according to a degree of the detected vibration. When there is a fear that the detected vibration may cause motion sickness, the control unit 2 decreases the luminous intensity of the room lamp 1. When the vibration of the vehicle becomes remarkable, the luminous intensity of the room lamp 1 is decreased. This disables an occupant from looking at a book or the like. Accordingly, the occupant is prevented from getting motion sickness.SELECTED DRAWING: Figure 1
【課題】読書等による乗員の乗り物酔いを防止するのに有効な車両用室内灯を提供する。【解決手段】車両に生じる振動を検出する振動検出手段4と、検出した振動の程度に応じて室内灯1の点灯を制御する点灯制御手段5を備えた制御ユニット2(ランプECU)を含む。制御ユニット2は、検出した振動が乗り物酔いを生じるおれそがあるときに室内灯1の光度を低下させる。車両の振動が顕著になると室内灯1の光度が低下されて乗員が書物等を視認できなくなり、乗り物酔いが防止される。【選択図】 図1
