PROBLEM TO BE SOLVED: To provide a vehicular lamp driving device and a vehicular lamp lighting system that can turn on an LED in a low rotation range of an engine without making a power generator large-sized.SOLUTION: The present invention relates to a vehicular lamp driving device that turns on vehicular lamps with an AC voltage of a power generator generating electricity through rotation of an engine, the vehicular lamp driving device comprising a boosting part which performs boosting operation to raise the AC voltage output to the lamps, a monitor part which determines whether the engine is in a low rotation state, and a boosting control part which controls the boosting operation based upon a determination result of the monitor part. The boosting control part performs control to let the boosting part performs the boosting operation when it is determined that the engine is in the low rotation state.SELECTED DRAWING: Figure 1
【課題】発電機を大型化せずにエンジンの低回転域においてLEDを点灯させることができる車両用ランプ駆動装置及び車両用ランプ点灯システムを提供する。【解決手段】エンジンの回転により発電する発電機の交流電圧により車両用のランプを点灯させる車両用ランプ駆動装置であって、前記ランプに出力される前記交流電圧を昇圧する昇圧動作を実行する昇圧部と、前記エンジンの回転状態が低回転状態であるか否かを判定する監視部と、前記監視部の判定結果に基づいて、前記昇圧動作を制御する昇圧制御部と、を備え、前記昇圧制御部は、前記エンジンの回転状態が低回転状態であると判定された場合には、前記昇圧部に対して前記昇圧動作を実行させるように制御する。【選択図】図1
