Abstract
【解決手段】実施形態によれば、標識灯は、複数の設定電流値を切り替えて電流を出力可能な交流定電流電源に対してトランスを介して結合される。前記標識灯は、前記交流定電流電源から電力を受けて点灯する光源と、前記交流定電流電源の出力電流の前記設定電流値に応じた明るさで前記光源が点灯するように前記光源を調光制御する制御装置と、を備えている。前記制御装置は、前記設定電流値が切り替わると、前記光源に対する調光比を連続的に変動させる。
【選択図】図2
Description
図3(b)において横軸は標識灯11への入力電流(A)を、縦軸は調光比(%)を表す。
図3(a)において横軸は標識灯11への入力電流(A)を、縦軸は調光比(%)を表す。
図4において横軸は標識灯11への入力電流を、縦軸は調光比を表す。
Claims (4)
- 複数の設定電流値を切り替えて電流を出力可能な交流定電流電源に対してトランスを介して結合される標識灯であって、
前記交流定電流電源から電力を受けて点灯する光源と、
前記交流定電流電源の出力電流の前記設定電流値に応じた明るさで前記光源が点灯するように前記光源を調光制御する制御装置であって、前記設定電流値が切り替わると、前記光源に対する調光比を連続的に変動させる制御装置と、
を備えた標識灯。 - 前記光源に対する電力供給をオンオフする負荷調整回路をさらに備え、
前記設定電流値の増加を検出してから前記負荷調整回路の動作を切り替えるまでの時間を、前記設定電流値の減少を検出してから前記負荷制御回路の動作を切り替えるまでの時間よりも短くした請求項1記載の標識灯。 - 前記設定電流値が切り替わると、前記調光比は直線的に変動する請求項1記載の標識灯。
- 前記調光比が1段階変化する区間において、前記調光比が一定の領域に対する、前記調光比が直線的に変動している領域の割合は、50%以下である請求項3記載の標識灯。
