To provide a technology which enhances an impression of a direction indication by movement of light in operating a sequential turn indicator by sequentially turning off.SOLUTION: A control device for lighting control of a vehicle lamp performs control of repeating a lighting cycle, wherein a plurality of light emitting parts are turned on from turned-off states and maintain lighting states, then the respective light emitting parts are turned off sequentially in a predetermined direction with a time difference and maintain turned-off states in one lighting cycle. The control device controls so that a rising time in turning on the respective turned-off light emitting parts becomes longer than a falling time in turning off the respective turned-on light emitting parts in controlling.SELECTED DRAWING: Figure 4
【課題】順次消灯によるシーケンシャルウインカーを行う際における光の移動による方向指示の印象をより強める技術を提供する。【解決手段】車両用灯具の点灯制御を行うための制御装置であって、複数の発光部を消灯から点灯にして点灯を維持した後に当該各発光部を時間差で所定方向へ順次消灯して当該消灯を維持することを1つの点灯周期として当該点灯周期を繰り返す制御を行い、制御の際に各前記発光部を消灯から点灯にする際の立ち上がり時間が各前記発光部を点灯から消灯にする際の立ち下がり時間よりも長くなるように制御する。【選択図】図4
