- 光源と、前記光源を点灯させる点灯回路と、所定の検知範囲における人の存在を検知して検知信号を出力する人感センサと、前記点灯回路を制御する制御部と、を備えた照明システムにおいて、
前記人感センサは、複数設けられ、
前記人感センサの各々は、共通の検知箇所を互いに異なる角度又は位置から検知し、
前記制御部は、
前記人感センサが検知信号を出力している検知時間を計測する検知時間計測手段と、
前記検知時間と前記光源を点灯保持させる点灯保持時間とを関連付ける情報を記憶した記憶手段とを備え、
前記制御部は、前記記憶手段を参照して前記検知時間計測手段が計測した検知時間に応じた点灯保持時間、前記光源を点灯保持させ、
前記点灯保持時間[s]は、人が前記人感センサの検知範囲に入る地点から前記光源の照射範囲を出る地点までの距離[m]を人の移動速度v[m/s]で割って算出した時間に基づいて決定される、ことを特徴とする照明システム。 - 前記人感センサの検知状態から非検知になって再度検知状態になるまでの時間間隔について設定された閾値を有し、
前記制御部は、前記時間間隔が前記閾値以下のとき、前記時間間隔とその前後の検知時間とを合算した時間を検知時間とみなすことを特徴とする請求項1に記載の照明システム。
