Description

【0001】
【発明の属する技術分野】
本発明は、照度センサ部や人感センサ部を用いて照明負荷の様々な動作を制御する照明装置に関するものである。
【0002】
【従来の技術】
この種の照明装置としては、図9に示すように、設置場所付近の照度を検知する照度センサ部13と、所定の検知エリア内において人の存否を検知する人感センサ部10と、照度センサ部13及び人感センサ部10の検知結果に基づいて照明負荷部16を点灯制御する器具制御部11とから構成されるものがあり、この照明装置は商用交流電源18’から電源供給されていた。
【0003】
この照明装置の動作を図10のタイムチャートにより説明する。人感センサ部10は人を検知すると、例えば論理”1”の検知信号S1 を出力し、人感センサ部10は人を検知しなければ、例えば論理”0”の検知信号S1 を出力する。一方、照度センサ部13の照度検知信号S4 が第1のしきい値たるしきい値L1 よりも暗ければ、照度センサ部13は低照度信号(例えば、論理”1”)を出力する。そして、器具制御部11は人感センサ部10から論理”1”の信号が入力されると、照度センサ部13の照度検知信号S4 を読み込み、照度センサ部13の照度検知信号S4 と人感センサ部10の検知信号S1 との論理積を求め、論理積の演算結果が論理”1”であれば、即ち、照度センサ部13が低照度信号を出力していれば、器具制御部11は照明負荷部16を点灯させていた。ここで、器具制御部11が照明負荷部16を点灯させると、照明装置に設けられた点灯保持タイマ(図示せず)が所定の点灯保持時間の限時動作を開始し、この点灯保持タイマが限時動作を終了するまでの間、器具制御部11は、照明負荷部16の点灯状態を維持するとともに、照度センサ部13の照度検知信号S4 を入力禁止とする。
【0004】
一方、照度センサ部13の照度検知信号S4 がしきい値L1 よりも明るければ、照度センサ部13は高照度信号(論理”0”)を出力するので、器具制御部11が照度センサ部13の照度検知信号S4 と人感センサ部10の検知信号S1 との論理積を求めると、論理積の演算結果は”0”となり、人感センサ部10が人を検知したとしても、器具制御部11が照明負荷部16を点灯させることはない。
【0005】
上述のように、この照明装置は照明器具本体に人感センサ部10を設けているので、人感センサ部10の検出信号は器具制御部11にリアルタイムで入力されており、器具制御部11は人感センサ部10の検知信号と照度センサ部13の検知信号との論理積をとり、その演算結果に基づいて照明負荷部を制御していた(特開平5−114489号参照)。
【0006】
また、図11に示すように、照明負荷部16を備えた照明器具本体1と、照明器具本体1にワイヤレス信号にて点灯信号を送信し、照明負荷部16の点灯状態を切り替えるリモコン送信器2とから構成される照明装置もあった。
照明器具本体1は、外部からワイヤレス信号で送信された点灯信号を受信する信号受信部12と、設置場所付近の照度を検知する照度センサ部13と、信号受信部12を介して受信した点灯信号及び照度センサ部13の照度検知信号S4 に基づいて照明負荷部16の点灯状態を制御する器具制御部11とから構成され、商用交流電源18’により各部の動作電源が供給されていた。
【0007】
また、リモコン送信器2は、所定の検知エリア内において人の存否を検知する人感センサ部22と、人感センサ部22の検知信号に基づいて照明負荷部16の点灯信号を発生するリモコン制御部21と、リモコン制御部21の点灯信号をワイヤレス信号で照明器具本体1へ送信する信号送信部23と、各種の操作を行うためのリモコン操作部24と、各部に動作電源を供給する電池部25’とから構成される。
【0008】
この照明装置では、照明器具本体1側に照度センサ部13を設けるとともに、リモコン送信器2側に人感センサ部22を設けており、リモコン送信器2に設けられた人感センサ部22が人を検知すると、リモコン制御部21は、人感センサ部22の検知信号に基づいて、照明負荷部16を点灯させる点灯信号を、信号送信部23から照明器具本体1へ送信させる。そして、照明器具本体1では、信号受信部12がリモコン送信器2から送信された点灯信号を受信し、器具制御部11がこの点灯信号に基づいて照明負荷部16を一定時間だけ点灯させる。
【0009】
この照明装置の動作を図12に示すタイムチャートを参照して説明する。この照明装置も、上述した図9の照明装置と同様に、人感センサ部22の検知エリア内に人が入ると、人感センサ部22がリアルタイムで人を検知し、リモコン制御部21は人感センサ部22の検知信号S1 に基づいて、送信信号S2 を信号送信部23から照明器具本体1へ送信させている。
【0010】
ところで、リモコン送信器2の動作電源は電池部25’から供給されているが、電池部25’の電池容量には限りがある。また、信号送信部23から照明器具本体1へ信号を送信する際に最も大きな電力を消費するので、図9の照明装置と同様に、人感センサ部22が人を検知する度に、毎回信号送信部23から照明器具本体1へ点灯信号を送信すると、信号送信部23の信号送信回数が膨大な回数になり、電池部25’の寿命が極端に短くなり、実用的でないという問題があった。
【0011】
そこでリモコン送信器2では、図12に示すように、時刻t29で人感センサ部22が初めて人を検知すると、リモコン制御部21が人感センサ部22の検知信号S1 に基づいて信号送信部23に送信信号(点灯信号)S2 を送信させるとともに、リトリガタイマ(図示せず)の限時動作を開始させる。ここに、リトリガタイマは所定の限時時間T1 を限時するタイマである。このリトリガタイマの限時動作中に人感センサ部22が人を検知しても、リモコン制御部21は、人感センサ部22が検知信号S1 を発生した履歴を記憶するのみで、信号送信部23に送信信号S2 を送信させることはない。その後、時刻t31でリトリガタイマが限時動作を終了すると、リモコン制御部21は人感センサ部22の履歴を確認し、リトリガタイマの限時動作中に人感センサ部22が人を検知していれば、時刻t31で信号送信部23から照明器具本体1へ再び送信信号S2 を送信させる。また、リトリガタイマの限時動作中に人感センサ部22が人を検知していなければ、リモコン制御部21は信号送信部23から照明器具本体1へ送信信号S2 を送信させない。
【0012】
照明器具本体1では、リモコン送信器2の送信信号S2 が信号受信部12を介して器具制御部11に入力されると、器具制御部11はその時点における照度センサ部13の照度検知信号S4 を読み込む。照度センサ部13には予め照度のしきい値L1 が設定されており、照度センサ部13が検知した照度がしきい値L1 よりも暗ければ、照度センサ部13は低照度信号を出力し、周囲の照度がしきい値L1 よりも明るければ、照度センサ部13は高照度信号を出力する。そして、器具制御部11は、照度センサ部13が低照度信号を出力していれば、照明負荷部16を点灯させるとともに、点灯保持タイマ(図示せず)に所定の点灯保持時間の限時動作を開始させ、点灯保持タイマの限時動作が終了するまでの間、照明負荷部16の点灯状態を維持するとともに、照度センサ部13の信号を入力禁止とする。
【0013】
このリモコン送信器2では、リトリガタイマの限時動作中に人感センサ部22が人を検知しても、信号送信部23は送信信号S2 を送信しないので、信号送信部23が送信信号S2 を送信する回数を減らすことにより、電池部28’の消耗を減らして、電池部28’の長寿命化を図っている。
【0014】
【発明が解決しようとする課題】
上述した図11に示す照明装置では、人感センサ部22が時刻t29で初めて人を検知すると、リモコン制御部21が信号送信部23を介して照明器具本体1に送信信号S2 を送信させるとともに、リトリガタイマが一定時間の限時動作を開始する。一方、照明器具本体1では、器具制御部11に信号受信部12を介して送信信号S2 が入力されると、器具制御部11はこの時点における照度センサ部13の照度検知信号S4 を読み込む。この時、周囲の照度がしきい値L1 よりも明るく、照度センサ部13が高照度信号を出力しているので、器具制御部11は照明負荷部16を点灯させていなかった。
【0015】
その後、リトリガタイマが限時動作中の時刻t30において、周囲の照度がしきい値L1 よりも暗くなると、照度センサ部13が低照度信号を出力するが、この時点ではリトリガタイマが依然として限時動作を行っているので、人感センサ部22が検知信号S1 を発生しても、リモコン制御部21が信号送信部23に送信信号S2 を送信させることはない。
【0016】
このように、リトリガタイマの限時動作中に、照明器具本体1の設置場所付近の照度がしきい値L1 より暗くなっても、リトリガタイマの限時動作が終了するまでの間、リモコン送信器2は照明器具本体1へ送信信号S2 を出力することができず、器具制御部11は照明負荷部16を点灯させることができないという問題があった。また、電池部25’の電池容量とこの種の照明装置の使用状況から見て、リトリガタイマの限時時間はかなり長い時間に設定されることが多く、リトリガタイマの限時時間が長いほど、照明負荷部16が点灯されない時間が長くなり、付近が暗くなって照明を必要とする時に、照明負荷部16を点灯させることができなかった。
【0017】
本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、周囲の照度変化に応じて照明負荷部を点灯させることができる照明装置を提供することにある。
【0018】
【課題を解決するための手段】
請求項1の発明では、上記目的を達成するために、周囲の照度を検知する照度センサ部と、照度のしきい値を設定する照度センサ制御部と、照明負荷部の点灯制御に関する信号を発生する信号入力手段と、信号入力手段が信号を発生した時点より一定時間を限時する第1のタイマ部と、照度センサ部の検知した照度が前記しきい値よりも暗い状態で信号入力手段から信号が入力されると、第1のタイマ部が一定時間の限時動作を終了するまでの間、照明負荷部を点灯させる器具制御部とを備え、器具制御部は、第1のタイマ部が一定時間を限時中に、照度センサ部の検知した照度が前記しきい値よりも暗くなると、第1のタイマ部の限時動作が終了するまで照明負荷部を点灯させるとともに、照明負荷部の点灯中に第1のタイマ部が計時した時間の経過に応じて、前記しきい値を消灯時の値よりも明るい所定値から徐々に暗い値に変化させることを特徴とする。
【0019】
請求項2の発明では、請求項1の発明において、第1のタイマ部の限時動作中に、照度センサ部の検知した照度が第1のしきい値よりも暗くなると、第1のタイマ部がリセットされ、再び一定時間の限時動作を開始するとともに、第1のタイマ部の限時動作が終了するまで、器具制御部が照明負荷部を点灯させることを特徴とする。
【0021】
請求項の発明では、請求項1の発明において、信号入力手段が人の存否を検知する人感センサ部からなり、請求項の発明では、信号入力手段が予め設定された時間にタイマ信号を発生する第2のタイマ部からなり、請求項の発明では、信号入力手段がワイヤレス信号で送信される点灯信号を受信する信号受信部からなり、請求項の発明では、信号入力手段が照明負荷部の点灯操作を行う操作部からなり、請求項の発明では、信号入力手段が各部に動作電源を供給する電源部からなり、器具制御部が電源部の電源投入信号と照度センサ部の照度検知信号に基づいて、照明負荷部を制御することを特徴とし、請求項の発明では、信号入力手段が、人の存否を検知する人感センサ部、予め設定された時間にタイマ信号を発生する第2のタイマ部、ワイヤレス信号で送信される点灯信号を受信する信号受信部、照明負荷部を点灯操作する操作部、及び、各部に動作電源を供給する電源部の内の複数の組み合わせからなることを特徴とする。
【0022】
【発明の実施の形態】
本発明の実施の形態を図面を参照して説明する。
基本構成1)
本発明に係る照明装置の基本構成を示すブロック図を図1に示し、その動作を説明するタイムチャートを図2に示す。
【0023】
照明器具本体1は、後述する各部の動作を制御する器具制御部11と、外部より赤外線光等の光信号からなるワイヤレス信号で送信された点灯信号を受信する信号入力手段たる信号受信部12と、照明器具本体1の設置場所付近の照度を検知する照度センサ部13と、照度のしきい値の設定など照度センサ部の様々な制御を行う照度センサ制御部14と、動作プログラムや設定値などを記憶するROM及びデータを記憶するRAMなどからなるメモリ部15と、器具制御部11によって点灯制御される照明負荷部16と、照明負荷部16の点灯/消灯などの操作や各種の設定を行うための操作部たる設定操作部17と、照明器具本体1の各部に動作電源を供給する電源部18と、照明負荷部16の点灯保持時間を計時する第1のタイマ部たる点灯保持タイマ19aとから構成される。
【0024】
リモコン送信器2は、後述する各部の動作を制御するリモコン制御部21と、人の存否を検知する人感センサ部22と、照明器具本体1へ赤外線光等の光信号からなるワイヤレス信号で点灯信号を送信する信号送信部23と、照明器具本体1の点灯/消灯などの遠隔操作や設定を行うためのリモコン操作部24と、リモコン送信器2の各部に動作電源を供給する電源部25と、信号送信部23が制御信号を送信してから一定時間を限時するリトリガタイマ26とから構成される。
【0025】
この照明装置の動作を図2のタイムチャートに従って説明する。時刻t1 でリモコン送信器2に設けられた人感センサ部22が初めて人を検知すると、リモコン制御部21は、人感センサ部22の検知信号S1 に基づいて、信号送信部23から照明器具本体1へ送信信号S2 (オン信号)を送信させるとともに、リトリガタイマ26に一定時間の限時動作を開始させる。
【0026】
照明器具本体1では、信号受信部12がリモコン送信器2から送信された送信信号S2 を受信し、器具制御部11に信号受信部12の受信信号S3 が入力されると、器具制御部11は照度センサ部13の照度検知信号S4 を読み込むとともに、照度検知信号S4 の明暗と無関係に点灯保持タイマ19aに所定の点灯保持時間の限時動作を開始させる。
【0027】
時刻t1 では、照度センサ部13の照度検知信号S4 が所定のしきい値L1 よりも明るく高照度信号を出力しているので、器具制御部11は、点灯保持タイマ19aが点灯保持時間の限時動作中であっても、照明負荷部16を点灯させることなく、消灯させる。その後、点灯保持タイマ19aが限時動作を継続している間、器具制御部11は照度センサ部13の照度検知信号S4 を逐次読み込み、時刻t2 において、照度センサ部13の照度検知信号S4 がしきい値L1 よりも暗くなり、低照度信号を出力すると、時刻t1 から点灯保持タイマ19aが限時動作を終了するまでの間、器具制御部11が照明負荷部16を点灯させる。
【0028】
ところで、時刻t1 で人感センサ部22が検知信号S1 を発生すると、リモコン制御部21がリトリガタイマ26の限時動作を開始させており、時刻t1 からリトリガタイマ26の限時動作が終了する時刻t3 までの間に、人感センサ部22が検知信号S1 を発生しても、リモコン制御部21は信号送信部23に送信信号S2 を送信させることなく、人感センサ部22が発生した検知信号S1 の履歴を記憶する。そして、時刻t1 から時刻t3 までの間に人感センサ部22が検知信号S1 を発生していれば、時刻t3 で、リモコン制御部21は信号送信部23から照明器具本体1へ送信信号S2 を送信させるとともに、リトリガタイマ26に再び一定時間の限時動作を開始させる。
【0029】
時刻t3 でリモコン送信器2が照明器具本体1へ送信信号S2 を送信すると、信号受信部12が送信信号S2 を受信する。信号受信部12から器具制御部11に受信信号S3 が入力されると、器具制御部11は点灯保持タイマ19aをリセットし、時刻t3 から点灯保持時間の限時動作を再開させるとともに、点灯保持タイマ19aの限時動作が終了するまでの間、照明負荷部16を点灯させる。ここで、点灯保持タイマ19aの限時時間は、リトリガタイマ26の限時時間よりも長い時間に設定されている。
【0030】
同様にして、時刻t3 から時刻t5 まで器具制御部11が照明負荷部16を点灯させた後、時刻t5 でリトリガタイマ26が限時動作を開始してから、時刻t6 でリトリガタイマ26が限時動作を終了するまでの間、人感センサ部22が検知信号S1 を発生しなかった場合、時刻t6 でリモコン制御部21は信号送信部23から照明器具本体1へ送信信号S2 を送信させない。したがって、照明器具本体1では、時刻t5 以降、信号受信部12がリモコン送信器2からの送信信号S2 を受信することができないので、点灯保持タイマ19aが点灯保持時間の限時動作を終了した時刻t7 で、器具制御部11は照明負荷部16を消灯させる。
【0031】
このように照明器具本体1では、信号受信部12がリモコン送信器1からの送信信号S2 を受信すると、先ず器具制御部11が、信号受信部12の受信信号S3 と、照度センサ部13の照度検知信号S4 との論理積を求める。ここで、受信信号S3 はオン信号ならば論理(1) 、オン信号以外ならば論理(0) とし、照度検知信号S4 は低照度信号ならば論理(1) 、高照度信号ならば論理(0) とする。そして、この論理積の演算結果が論理(1) の場合、器具制御部11は、点灯保持タイマ19aの限時動作を開始させるとともに、点灯保持タイマ19aの限時動作が終了するまで、照明負荷部16を点灯させる。一方、論理積の演算結果が論理(0) の場合、器具制御部11は、照明負荷部16を点灯させず、点灯保持タイマ19aの限時動作を開始させ、点灯保持タイマ19aの動作状態と照度検知信号S4 との論理積を逐次求める。尚、点灯保持タイマ19aが限時動作中であれば論理(1) 、点灯保持タイマ19aが限時動作を終了すれば論理(0) とする。そして、この論理積の演算結果が論理(1) になれば、その時点から点灯保持タイマ19aが限時動作を終了するまでの間、器具制御部11が照明負荷部16を点灯させ、論理積の演算結果が論理(0) になれば、器具制御部11が照明負荷部16を消灯させる。
【0032】
したがって、リモコン送信器2では、リトリガタイマ26の限時動作中に、人感センサ部22が検知信号S1 を発生しても、送信信号S2 を送信しないので、送信信号S2 の送信回数を減らすことができ、電源部25の消耗を少なくして、長寿命化を図ることができる。また、照明器具本体1はリモコン送信器2から送信信号S2 を受信しても、その時点における周囲の照度がしきい値L1 よりも明るければ、器具制御部11は照明負荷部16を点灯させることなく消灯させ、点灯保持タイマ19aの限時動作を開始させる。そして、点灯保持タイマ19aの限時動作中に周囲の照度がしきい値L1 よりも暗くなれば、器具制御部11は照明負荷部16を点灯させているので、周囲が暗くなり照明を必要とする時には、直ぐに器具制御部11が照明負荷部16を点灯させることができる。
【0033】
尚、この照明装置では、信号入力手段としてリモコン送信器2の送信信号を受信する信号受信部12を用いているが、図3に示すように、信号受信部12の代わりに、例えば人感センサ部からなる信号入力手段12’を設け、器具制御部11が、信号入力手段12’から入力さる信号と照度センサ部13の照度検知信号Sとの論理積を演算するようにしても良いし、信号入力手段として電源部18を用い、器具制御部11が、電源部18の電源投入信号と照度センサ部13の照度検知信号11とに基づいて、照明負荷部16の点灯制御を行ってもよい。
【0034】
また、この照明装置では、照明器具本体1がリモコン送信器2から送信信号Sを受信した時点で、照度センサ部13の照度検知信号Sがしきい値Lよりも明るい場合、器具制御部11は照明負荷部16を消灯させる。その後、点灯保持タイマ19aの限時動作中、器具制御部11は照度センサ部13の照度検知信号Sを逐次読み込み、照度検知信号Sがしきい値Lよりも暗くなると、その時点から点灯保持タイマ19aの限時動作が終了するまでの間、器具制御部11が照明負荷部16を点灯させているが、図4に示すように、照度センサ部13の照度検知信号Sがしきい値Lよりも暗くなった時刻tで、点灯保持タイマ19aの限時動作をリセットし、時刻tから所定の点灯保持時間の限時動作を再開させ、時刻tから点灯保持タイマ19aの限時動作が終了する時刻t10までの間、器具制御部11が照明負荷部16を点灯させるようにしてもよい。
【0035】
基本構成2)
ところで、一般に照度センサ部13を備えた照明装置において、照明負荷部16の点灯後も、器具制御部11が照度センサ部13の照度検知信号Sに基づいて照明負荷部16を点灯制御していると、照明負荷部16の点灯によって照度センサ部13の照度検知信号Sが所定のしきい値Lを大きく上回って、器具制御部11が照明負荷部16を消灯させるため、照明装置が自己点滅を繰り返すというトラブルが発生する恐れがある。
【0036】
そこで以下に説明する照明装置では、基本構成1で説明した照明装置において、照明負荷部16が点灯してから消灯するまでの間、器具制御部11が照度センサ部16の照度検知信号Sを入力禁止にしている。尚、照明装置の構成は基本構成1で説明した照明装置と同様であるので、その説明は省略する。
図5に示すように、時刻tにおいて照度センサ部13の照度検知信号Sがしきい値Lよりも暗くなると、器具制御部11は照明負荷部16を点灯させる。この時、照明負荷部16の点灯によって、照度センサ部13の照度検知信号Sは照度のしきい値Lを遙かに上回り、高照度信号を出力する。ここで、照明負荷部16が点灯中(時刻tから時刻tまで)は、器具制御部11が照度センサ部13の照度検知信号Sを入力禁止としているので、照度センサ部13が高照度信号を出力しても、器具制御部11は照度センサ部13の照度検知信号Sを無視して、点灯保持タイマ19aの限時動作が終了するまでの間、照明負荷部16を継続して点灯させることができ、照明負荷部16が自己点滅するというトラブルを防止することができる。
【0037】
ところで、この照明装置では、照明負荷部16の点灯中に、器具制御部11が照度センサ部13の照度検知信号Sを入力禁止にしているが、照明負荷部16の点灯中に、照度センサ部13の動作を停止させても良い。
尚、照明負荷部16の点灯中に照度センサ部13の照度検知信号Sを入力禁止とする点以外は、図2に示す基本構成1の照明装置の動作と同様であるので、その説明は省略する。
【0038】
(実施形態
本実施形態の照明装置の動作を図6のタイムチャートを参照して説明する。尚、照明装置の構成は基本構成1で説明した照明装置と同様であるので、その説明は省略する。時刻t11で、人感センサ部22が検知信号Sを発生し、リモコン送信器2が照明器具本体1へ送信信号Sを送信すると、照明器具本体1の信号受信部12がリモコン送信器2からの送信信号Sを受信する。器具制御部11に信号受信部12から受信信号Sが入力されると、器具制御部11は、照度センサ部13の照度検知信号Sを読み込むとともに、点灯保持タイマ19aに所定の点灯保持時間の限時動作を開始させる。ここで、時刻t11では、照度センサ部13の照度検知信号Sが第1のしきい値Lよりも明るく、高照度信号を出力しているので、器具制御部11は照明負荷部16を点灯させず、消灯させている。
【0039】
その後、時刻t12で照度センサ部13の照度検知信号S4 が第1のしきい値L2 よりも暗くなると、時刻t12から点灯保持タイマ19aの限時動作が終了するまでの間、器具制御部11が照明負荷部16を点灯させる。ここで、照明負荷部16の点灯中は、照度センサ制御部14が、照度のしきい値を第1のしきい値L2 よりも明るい第2のしきい値L3 に切り替えている。
【0040】
このように、照明負荷部16が点灯している間、照度センサ制御部14が照度のしきい値を第2のしきい値L3 に切り替えているので、照明負荷部16が点灯しても、照度センサ部13の照度検知信号S4 が第2のしきい値L3 よりも暗くなり、照度センサ部13が低照度信号を出力するので、器具制御部11は照明負荷部16の点灯状態を維持する。
【0041】
ところで、器具制御部11が照明負荷部16を点灯させた後も、器具制御部11は照度センサ部13の照度検知信号S4 を逐次読み込んでおり、時刻t14で、例えば窓から太陽光線などの外光が入射し、照度センサ部13の照度検知信号S4 が第2のしきい値L3 よりも明るくなり、高照度信号を出力すると、器具制御部11は照明負荷部16を消灯させる。尚、器具制御部11が照明負荷部16を消灯させると、照度センサ制御部14は照度のしきい値を第2のしきい値L3 から第1のしきい値L2 に戻している。
【0042】
このように、照明負荷部16の点灯後も、器具制御部11が、照度センサ部13の照度検知信号S4 に基づいて、照明負荷部16の点灯制御を行っているので、照明負荷部16の点灯後に外光等が入射して異常に明るくなった場合に、器具制御部11が照明負荷部16を消灯させて、照明負荷部16が無駄に点灯するのを防止することができる。
【0043】
尚、本実施形態では、照度センサ部13の照度検知信号S4 のしきい値として、照度センサ制御部14が第1及び第2のしきい値L2 ,L3 (照明負荷部16の点灯時と消灯時)の2種類のしきい値を設けたが、照度のしきい値を可変とし、照明負荷部16を点灯した後の周囲の照度に応じて、照度センサ制御部14が照度のしきい値を複数段設定しても良いし、例えば点灯保持タイマ19aの計時時間の経過とともに、照度のしきい値を除々に暗くしても良いし、照度のしきい値を連続的に設定しても良い。
【0044】
(実施形態
実施形態1および基本構成1、2の照明装置では、信号入力手段として、リモコン送信器2からの送信信号Sを受信する信号受信部12や、人の存否を検知する人感センサ部を用いているが、本実施形態の照明装置では、図7に示すように、信号入力手段として所定の時刻にタイマ信号を発生する第2のタイマ部たるタイマ19bを用いている。
【0045】
例えば、リモコン送信器2のリモコン操作部24で照明負荷部16の点灯/消灯操作を行ったり、リモコン送信器2に設けられた人感センサ部22が人を検知したりすると、器具制御部11が照明負荷部16を点灯させるような照明装置では、人感センサ部22が人を検知した場合に器具制御部11が照明負荷部16を点灯制御する制御内容について、複数の点灯モードが器具制御部11に設定されている。例えばタイマ19bに各点灯モードの時間帯が予め設定されており、タイマ19bのタイマ信号に応じて点灯モードが順次切り替わって行く。
【0046】
図8に示すように、器具制御部11の点灯モードMDとして、通常の”アクティブモード”と、”お出迎えモード”の二つの点灯モードがある場合について説明する。ここで、器具制御部11の点灯モードMDは、予め設定されたタイマによって、時刻t21(例えば午後6時)で”アクティブモード”から”お出迎えモード”に切り替わっている。
【0047】
まず、”アクティブモード”では、基本構成1で説明した照明装置と同様に、リモコン送信器2に設けた人感センサ部22の検知信号と、照明器具本体1に設けた照度センサ部13の照度検知信号Sに基づいて、器具制御部11が照明負荷部16を点灯制御している。例えば時刻t19で、リモコン送信器2の人感センサ部22が人を検知し、器具制御部11に信号受信部12の受信信号Sが入力されると、器具制御部11は照度センサ部13の照度検知信号Sを読み込むとともに、点灯保持タイマ19aに所定の点灯保持時間の限時動作を開始させる。この時、照度センサ部13の照度検知信号Sはしきい値Lよりも暗く、低照度信号を出力しているので、点灯保持タイマ19aが限時動作を終了するまでの間、器具制御部11が照明負荷部16を全点灯(例えば、100%の調光レベル)させる。その後、点灯保持タイマ19aの限時動作が終了するまでに、信号受信部12がリモコン送信器2の送信信号を受信しなければ、点灯保持タイマ19aの限時動作が終了する時刻t20で、器具制御部11が照明負荷部16を消灯させる。
【0048】
一方、”お出迎えモード”では、人感センサ部22が人を検知していなくても、器具制御部11が照明負荷部16をある一定の調光レベル(例えば、30%の調光レベル)で調光点灯し、人感センサ部22が人を検知して、器具制御部11に信号受信部12の受信信号S3 が入力されると、器具制御部11が照明負荷部16を所定の点灯保持時間だけ全点灯させる。
【0049】
ここで、時刻t21で器具制御部11へタイマ19bのタイマ信号が入力されると、器具制御部11の点灯モードMDが”アクティブモード”から”お出迎えモード”に切り替わり、器具制御部11が、お出迎えモードの設定時間を限時するお出迎えタイマ19cが限時動作を開始させるとともに、照度センサ部13の照度検知信号S4 及びお出迎えタイマ19cの動作状態とを読み込む。そして、器具制御部11は、照度センサ部13の照度検知信号S4 と、お出迎えタイマ19cの動作状態との論理積を求め、論理積の演算結果が論理(1) であれば、器具制御部11が照明負荷部16を調光点灯させ、論理積の演算結果が論理(0) であれば、器具制御部11が照明負荷部16を消灯させる。尚、照度センサ部13の照度検知信号S4 はしきい値L1 よりも暗ければ論理(1) 、しきい値L1 よりも明るければ論理(0) とし、お出迎えタイマ19cの動作状態は限時動作中であれば論理(1) 、限時動作を終了していれば論理(0) とする。
【0050】
ところで、時刻t21では、照度センサ部13の照度検知信号S4 はしきい値L4 よりも明るく、高照度信号を出力しており〔論理(0) 〕、器具制御部11が照度センサ部13の照度検知信号S4 とお出迎えタイマ19cの動作状態との論理積を求めると、論理積の演算結果が論理(0) となるので、器具制御部11は照明負荷部16を点灯させることなく、消灯させる。その後も、お出迎えタイマ19cの限時動作中に器具制御部11が照度センサ部13の照度検知信号S4 を逐次読み込み、照度検知信号S4 とお出迎えタイマ19cの動作状態との論理積を演算しており、時刻t22で、照度センサ部13の照度検知信号S4 がしきい値L1 よりも暗く、低照度信号になると〔論理(1) 〕、論理積の演算結果が論理(1) となり、器具制御部11は照明負荷部16を調光点灯させる。
【0051】
その後、時刻t23で信号受信部12がリモコン送信器1からの送信信号を受信すると、器具制御部11は、信号受信部12の受信信号S3 に基づいて、点灯保持タイマ19aの限時動作が終了する時刻t24までの間、照明負荷部16を全点灯させる。
また時刻t25で信号受信部12がリモコン送信器1からの送信信号を受信すると、器具制御部11は信号受信部12の受信信号S3 に基づいて点灯保持タイマ19aの限時動作を開始させるとともに、照明負荷部16を全点灯させる。その後、点灯保持タイマ19aの限時動作が終了するまでに、時刻t26,t27で信号受信部12が受信信号S3 を受信すると、その都度点灯保持タイマ19aがリセットされ、その時点から再び点灯保持時間の限時動作を開始するので、信号受信部12が受信信号S3 を最後に受信した時刻t27から、点灯保持タイマ19aが点灯保持時間の限時動作を終了した時刻t28まで、器具制御部11は照明負荷部16を全点灯させる。
【0052】
尚、上述の実施形態では、信号入力手段として、リモコン送信器2からの信号を受信する信号受信部12や、人の存否を検知する人感センサ部や、所定の時刻にタイマ信号を発生するタイマ19bを用いているが、信号入力手段として、設定操作部17、或いは、電源部18を用い、器具制御部11が、設定操作部17の操作信号、或いは、電源部18の電源投入信号と、照度センサ部13の照度検知信号とに基づいて、照明負荷部を点灯制御しても良い。また、信号入力手段を、信号受信部12、人感センサ部、タイマ部19b、設定操作部17及び電源部18の内の複数の組み合わせとしても良い。

BACKGROUND OF THE INVENTION
The present invention relates to a lighting device that controls various operations of a lighting load using an illuminance sensor unit and a human sensor unit.
[0002]
[Prior art]
As this type of lighting device, as shown in FIG. 9, an illuminance sensor unit 13 that detects illuminance near the installation location, a human sensor unit 10 that detects presence or absence of a person in a predetermined detection area, and an illuminance sensor And the appliance control unit 11 that controls lighting of the illumination load unit 16 based on the detection results of the unit 13 and the human sensor unit 10, and this illumination device is supplied with power from a commercial AC power supply 18 '. .
[0003]
The operation of this lighting device will be described with reference to the time chart of FIG. When the human sensor 10 detects a person, for example, a detection signal S of logic “1” is detected.1If the human sensor 10 does not detect a person, for example, a detection signal S of logic “0” is output.1Is output. On the other hand, the illuminance detection signal S of the illuminance sensor unit 13FourIs the first threshold value L1If it is darker, the illuminance sensor unit 13 outputs a low illuminance signal (for example, logic “1”). When the appliance control unit 11 receives a logic “1” signal from the human sensor unit 10, the illuminance detection signal S of the illuminance sensor unit 13 is input.FourIlluminance detection signal S of the illuminance sensor unit 13FourAnd the detection signal S of the human sensor unit 101If the logical product is “1”, that is, if the illuminance sensor unit 13 outputs a low illuminance signal, the appliance control unit 11 turns on the illumination load unit 16. It was. Here, when the fixture control unit 11 turns on the lighting load unit 16, a lighting holding timer (not shown) provided in the lighting device starts a timed operation for a predetermined lighting holding time, and this lighting holding timer is timed. Until the operation ends, the appliance control unit 11 maintains the lighting state of the illumination load unit 16 and the illuminance detection signal S of the illuminance sensor unit 13.FourIs prohibited.
[0004]
On the other hand, the illuminance detection signal S of the illuminance sensor unit 13FourIs the threshold L1If it is brighter, the illuminance sensor unit 13 outputs a high illuminance signal (logic “0”), so that the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.FourAnd the detection signal S of the human sensor unit 101The logical product operation result is “0”, and the appliance control unit 11 does not light the lighting load unit 16 even if the human sensor unit 10 detects a person.
[0005]
As described above, since this lighting device is provided with the human sensor unit 10 in the lighting fixture main body, the detection signal of the human sensor unit 10 is input to the appliance controller 11 in real time. A logical product of the detection signal of the human sensor unit 10 and the detection signal of the illuminance sensor unit 13 is obtained, and the illumination load unit is controlled based on the calculation result (see Japanese Patent Application Laid-Open No. 5-114489).
[0006]
Moreover, as shown in FIG. 11, the lighting fixture main body 1 provided with the lighting load part 16, and the remote control transmitter 2 which transmits a lighting signal with a wireless signal to the lighting fixture main body 1, and switches the lighting state of the lighting load part 16. There was also a lighting device composed of
The luminaire main body 1 includes a signal receiving unit 12 that receives a lighting signal transmitted as a wireless signal from the outside, an illuminance sensor unit 13 that detects illuminance near the installation location, and a lighting signal received via the signal receiving unit 12. And the illuminance detection signal S of the illuminance sensor unit 13FourAnd an appliance control unit 11 for controlling the lighting state of the illumination load unit 16, and operating power for each unit is supplied by a commercial AC power supply 18 ′.
[0007]
The remote control transmitter 2 also includes a human sensor 22 that detects the presence or absence of a person in a predetermined detection area, and a remote control that generates a lighting signal for the illumination load unit 16 based on a detection signal from the human sensor 22. Unit 21, a signal transmission unit 23 that transmits a lighting signal of the remote control unit 21 to the luminaire main body 1 by a wireless signal, a remote control operation unit 24 for performing various operations, and a battery unit that supplies operation power to each unit 25 '.
[0008]
In this lighting device, an illuminance sensor unit 13 is provided on the luminaire main body 1 side, and a human sensor unit 22 is provided on the remote control transmitter 2 side. The human sensor unit 22 provided on the remote control transmitter 2 is a human sensor. Is detected, the remote control control unit 21 transmits a lighting signal for lighting the lighting load unit 16 from the signal transmission unit 23 to the lighting fixture body 1 based on the detection signal of the human sensor unit 22. And in the lighting fixture main body 1, the signal receiving part 12 receives the lighting signal transmitted from the remote control transmitter 2, and the appliance control part 11 lights the lighting load part 16 only for a fixed time based on this lighting signal.
[0009]
The operation of this lighting device will be described with reference to the time chart shown in FIG. Similarly to the lighting device of FIG. 9 described above, when the person enters the detection area of the human sensor unit 22, the human sensor unit 22 detects the person in real time, and the remote control unit 21 Detection signal S of the sensation sensor unit 221Based on the transmitted signal S2Is transmitted from the signal transmission unit 23 to the luminaire main body 1.
[0010]
By the way, although the operation power supply of the remote control transmitter 2 is supplied from the battery unit 25 ′, the battery capacity of the battery unit 25 ′ is limited. Further, since the largest amount of power is consumed when transmitting a signal from the signal transmission unit 23 to the lighting fixture body 1, every time the human sensor unit 22 detects a person, as in the lighting device of FIG. When a lighting signal is transmitted from the transmission unit 23 to the luminaire main body 1, the signal transmission number of the signal transmission unit 23 becomes enormous, and the life of the battery unit 25 ′ becomes extremely short, which is not practical. .
[0011]
Therefore, in the remote control transmitter 2, as shown in FIG.29When the human sensor 22 detects a person for the first time, the remote control controller 21 detects the detection signal S of the human sensor 22.1Based on the transmission signal (lighting signal) S to the signal transmission unit 232And a time limit operation of a retrigger timer (not shown) is started. Here, the retrigger timer has a predetermined time limit T1It is a timer that limits time. Even if the human sensor 22 detects a person during the time limit operation of the retrigger timer, the remote controller 21 will detect that the human sensor 22 has a detection signal S.1The transmission signal S is sent to the signal transmission unit 23 only by storing the history of occurrence of2Will not be sent. Then time t31When the retrigger timer ends the time limit operation, the remote controller control unit 21 confirms the history of the human sensor unit 22, and if the human sensor unit 22 detects a person during the time limit operation of the retrigger timer, the time t31The transmission signal S from the signal transmission unit 23 to the luminaire body 1 again2To send. Further, if the human sensor 22 does not detect a person during the time limit operation of the retrigger timer, the remote control controller 21 transmits a transmission signal S from the signal transmitter 23 to the luminaire body 1.2Will not be sent.
[0012]
In the luminaire main body 1, the transmission signal S of the remote control transmitter 22Is input to the appliance control unit 11 via the signal receiving unit 12, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13 at that time.FourIs read. The illuminance sensor unit 13 has an illuminance threshold value L in advance.1Is set, and the illuminance detected by the illuminance sensor unit 13 is the threshold value L.1If it is darker, the illuminance sensor unit 13 outputs a low illuminance signal, and the ambient illuminance is the threshold value L.1If it is brighter, the illuminance sensor unit 13 outputs a high illuminance signal. Then, if the illuminance sensor unit 13 outputs a low illuminance signal, the appliance control unit 11 turns on the lighting load unit 16 and causes a lighting holding timer (not shown) to perform a timed operation for a predetermined lighting holding time. The lighting load unit 16 is kept in the lighting state and the signal from the illuminance sensor unit 13 is prohibited from being input until the time limit operation of the lighting holding timer ends.
[0013]
In this remote control transmitter 2, even if the human sensor unit 22 detects a person during the time limit operation of the retrigger timer, the signal transmission unit 23 transmits the transmission signal S.2Is not transmitted, the signal transmission unit 23 transmits the transmission signal S.2By reducing the number of times of transmission, the consumption of the battery unit 28 ′ is reduced and the life of the battery unit 28 ′ is extended.
[0014]
[Problems to be solved by the invention]
In the illumination device shown in FIG. 11 described above, the human sensor unit 22 is at time t.29When the person is detected for the first time, the remote controller control unit 21 transmits the transmission signal S to the luminaire main body 1 via the signal transmission unit 23.2And the retrigger timer starts a timed operation for a fixed time. On the other hand, in the lighting fixture body 1, the transmission signal S is sent to the fixture control unit 11 via the signal receiving unit 12.2Is input, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13 at this time.FourIs read. At this time, the ambient illuminance is the threshold value L1Since the illuminance sensor unit 13 outputs a high illuminance signal, the appliance control unit 11 did not light the illumination load unit 16.
[0015]
After that, the time t when the retrigger timer is operating for a time limit30, The ambient illuminance is the threshold value L1When it becomes darker, the illuminance sensor unit 13 outputs a low illuminance signal. At this time, the retrigger timer is still operating for a limited time, so the human sensor unit 22 detects the detection signal S.1Even when the remote control unit 21 generates a transmission signal S to the signal transmission unit 23.2Will not be sent.
[0016]
Thus, during the time limit operation of the retrigger timer, the illuminance near the installation location of the luminaire body 1 is the threshold value L.1Even if it becomes darker, the remote control transmitter 2 transmits the transmission signal S to the luminaire main body 1 until the time limit operation of the retrigger timer ends.2Cannot be output, and the appliance control unit 11 cannot illuminate the illumination load unit 16. Further, in view of the battery capacity of the battery unit 25 ′ and the usage status of this type of lighting device, the time limit of the retrigger timer is often set to a considerably long time, and the longer the time limit of the retrigger timer is, the longer the lighting load unit 16 The lighting load unit 16 could not be lit when the time during which the light is not turned on becomes longer and the vicinity becomes dark and illumination is required.
[0017]
The present invention has been made in view of the above problems, and an object of the present invention is to provide an illuminating device capable of lighting an illumination load unit according to a change in ambient illuminance.

Time t1When the human sensor unit 22 provided in the remote control transmitter 2 detects a person for the first time, the remote controller control unit 21 detects the detection signal S of the human sensor unit 22.1Based on the transmission signal S from the signal transmission unit 23 to the luminaire main body 1.2(ON signal) is transmitted, and the retrigger timer 26 is started to operate for a fixed time.
[0026]
In the luminaire main body 1, the signal reception unit 12 transmits the transmission signal S transmitted from the remote control transmitter 2.2And the received signal S of the signal receiver 12 is sent to the appliance controller 11.ThreeIs input, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.FourIlluminance detection signal SFourRegardless of the brightness, the lighting holding timer 19a starts a time-limited operation for a predetermined lighting holding time.
[0027]
Time t1Then, the illuminance detection signal S of the illuminance sensor unit 13FourIs a predetermined threshold L1Since the brighter and higher illuminance signal is output, the appliance control unit 11 turns off the lighting load unit 16 without turning it on even when the lighting holding timer 19a is operating for a limited time of the lighting holding time. Thereafter, while the lighting holding timer 19a continues the time limit operation, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.FourAre sequentially read and time t2, The illuminance detection signal S of the illuminance sensor unit 13FourIs the threshold L1When it becomes darker and a low illumination signal is output, the time t1Until the lighting holding timer 19a ends the time limit operation, the appliance control unit 11 lights the lighting load unit 16.
[0028]
By the way, time t1The human sensor unit 22 detects the detection signal S.1Is generated, the remote controller control unit 21 starts the time limit operation of the retrigger timer 26, and the time t1To the time t at which the time limit operation of the retrigger timer 26 endsThreeUntil the human sensor 22 detects the detection signal S1Even when the remote control unit 21 generates the transmission signal S,2The detection signal S generated by the human sensor 22 without transmitting1Remember the history. And time t1To time tThreeUntil the human sensor 22 detects the detection signal S1Is generated, the time tThreeThen, the remote control unit 21 transmits the transmission signal S from the signal transmission unit 23 to the lighting fixture body 1.2And the retrigger timer 26 again starts a time-limited operation for a fixed time.
[0029]
Time tThreeThe remote control transmitter 2 sends a transmission signal S to the lighting fixture body 1.2, The signal receiving unit 12 transmits the transmission signal S.2Receive. Receive signal S from signal receiver 12 to instrument controller 11ThreeIs input, the appliance control unit 11 resets the lighting holding timer 19a, and the time tThreeThe lighting load unit 16 is turned on until the timed operation of the lighting holding time is resumed and the timed operation of the lighting holding timer 19a ends. Here, the time limit of the lighting hold timer 19a is set to be longer than the time limit of the retrigger timer 26.
[0030]
Similarly, time tThreeTo time tFiveUntil the fixture control unit 11 turns on the illumination load unit 16 until time tFiveAt time t after the retrigger timer 26 starts the time limit operation.6Until the retrigger timer 26 finishes the time limit operation, the human sensor unit 22 detects the detection signal S.1T does not occur, the time t6Then, the remote control control unit 21 transmits the transmission signal S from the signal transmission unit 23 to the lighting fixture body 1.2Will not be sent. Therefore, in the lighting fixture body 1, the time tFiveThereafter, the signal receiving unit 12 transmits the transmission signal S from the remote control transmitter 2.2Since the lighting hold timer 19a has finished the time-limited operation of the lighting holding time, the time t7Thus, the appliance control unit 11 turns off the illumination load unit 16.
[0031]
As described above, in the luminaire main body 1, the signal receiving unit 12 transmits the transmission signal S from the remote control transmitter 1.2First, the instrument control unit 11 receives the received signal S from the signal receiving unit 12.ThreeAnd the illuminance detection signal S of the illuminance sensor unit 13FourFind the logical product of Here, the received signal SThreeIs logic (1) if the signal is on, and logic (0) if it is not an on signal.FourIs logic (1) for low illuminance signals and logic (0) for high illuminance signals. When the logical product operation result is logic (1), the appliance control unit 11 starts the time limit operation of the lighting hold timer 19a and the lighting load unit 16 until the time limit operation of the light holding timer 19a ends. Lights up. On the other hand, when the operation result of the logical product is logic (0), the appliance control unit 11 does not turn on the lighting load unit 16 and starts the time limit operation of the lighting holding timer 19a, and the operating state and illuminance of the lighting holding timer 19a. Detection signal SFourIs obtained sequentially. It should be noted that the logic (1) is set when the lighting holding timer 19a is in a time limit operation, and the logic (0) is set when the lighting holding timer 19a finishes the time limit operation. When the logical product operation result is logical (1), the appliance control unit 11 lights the lighting load unit 16 from that time until the lighting hold timer 19a finishes the time limit operation. When the calculation result becomes logic (0), the appliance control unit 11 turns off the illumination load unit 16.
[0032]
Therefore, in the remote control transmitter 2, during the time limit operation of the retrigger timer 26, the human sensor unit 22 detects the detection signal S.1Is generated, the transmission signal S2Is not transmitted, so the transmission signal S2The number of transmissions can be reduced, consumption of the power supply unit 25 can be reduced, and the life can be extended. Further, the luminaire body 1 receives a transmission signal S from the remote control transmitter 2.2, The ambient illuminance at that time is the threshold value L1If it is brighter, the appliance control unit 11 turns off the lighting load unit 16 without turning it on, and starts the time limit operation of the lighting holding timer 19a. Then, during the time limit operation of the lighting hold timer 19a, the ambient illuminance is the threshold value L1If it becomes darker than that, the appliance control unit 11 lights the illumination load unit 16, so that the appliance control unit 11 can immediately turn on the illumination load unit 16 when the surroundings become dark and illumination is required.
[0033]
  still,This lighting deviceIn FIG. 3, the signal receiving unit 12 that receives the transmission signal of the remote control transmitter 2 is used as the signal input means. However, as shown in FIG. Means 12 ′ is provided, and the appliance control unit 11 receives a signal input from the signal input means 12 ′ and the illuminance detection signal S of the illuminance sensor unit 13.4The power supply unit 18 is used as a signal input unit, and the appliance control unit 11 is based on the power-on signal of the power supply unit 18 and the illuminance detection signal 11 of the illuminance sensor unit 13. Then, the lighting control of the illumination load unit 16 may be performed.
[0034]
  Also,This lighting deviceThen, the luminaire main body 1 transmits the transmission signal S from the remote control transmitter 2.2Is received, the illuminance detection signal S of the illuminance sensor unit 13 is received.4Is the threshold L1If it is brighter, the appliance control unit 11 turns off the illumination load unit 16. Thereafter, during the time limit operation of the lighting hold timer 19a, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.4Are read sequentially, and the illuminance detection signal S4Is the threshold L1When it becomes darker, the appliance control unit 11 lights the illumination load unit 16 from that time until the time limit operation of the lighting hold timer 19a ends, but as shown in FIG. Illuminance detection signal S4Is the threshold L1Time t darker than9The reset operation of the lighting hold timer 19a is reset at time t9The time-limited operation for a predetermined lighting holding time is restarted from time t9To the time t at which the timed operation of the lighting hold timer 19a ends.10Until then, the appliance control unit 11 may light the illumination load unit 16.
[0035]
  (Basic configuration2)
  By the way, generally in the illuminating device provided with the illuminance sensor unit 13, even after the illumination load unit 16 is turned on, the appliance control unit 11 performs the illuminance detection signal S of the illuminance sensor unit 13.4If the lighting load unit 16 is controlled to be lit based on the illuminance load unit 16, the illuminance detection signal S of the illuminance sensor unit 13 is turned on by the lighting of the lighting load unit 16.4Is a predetermined threshold L1Since the appliance control unit 11 turns off the lighting load unit 16, the lighting device may repeat a self-flashing problem.
[0036]
  ThereforeIn the lighting device described below, the basic configuration 1 has been described.In the illuminating device, the illuminance detection signal S of the illuminance sensor unit 16 is received by the appliance control unit 11 from when the illumination load unit 16 is lit until it is extinguished.4Is prohibited. The configuration of the lighting device isDescribed in Basic Configuration 1Since it is the same as that of the illumination device, its description is omitted.
  As shown in FIG.2Illuminance detection signal S of the illuminance sensor unit 13 in FIG.4Is the threshold L1When it becomes darker than that, the appliance control unit 11 turns on the illumination load unit 16. At this time, the illuminance detection signal S of the illuminance sensor unit 13 is generated by lighting of the illumination load unit 16.4Is the illuminance threshold L1It is far above and outputs a high illuminance signal. Here, the illumination load unit 16 is lit (time t2To time t7Until the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.4Therefore, even if the illuminance sensor unit 13 outputs a high illuminance signal, the appliance control unit 11 does not detect the illuminance detection signal S of the illuminance sensor unit 13.4And the lighting load unit 16 can be lit continuously until the time limit operation of the lighting holding timer 19a ends, and the trouble that the lighting load unit 16 flashes on itself can be prevented.
[0037]
  by the way,This lighting deviceThen, while the illumination load unit 16 is lit, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.4However, the operation of the illuminance sensor unit 13 may be stopped while the illumination load unit 16 is lit.
  Note that the illuminance detection signal S of the illuminance sensor unit 13 while the illumination load unit 16 is lit.42 except that input is prohibitedBasic configuration 1Since the operation is the same as that of the lighting device, description thereof is omitted.
[0038]
  (Embodiment1)
  The operation of the illumination device of this embodiment will be described with reference to the time chart of FIG. The configuration of the lighting device isLighting device described in Basic Configuration 1Since this is the same, the description thereof is omitted. Time t11Therefore, the human sensor 22 detects the detection signal S.1And the remote control transmitter 2 sends a transmission signal S to the lighting fixture body 1.2, The signal receiver 12 of the luminaire body 1 transmits the transmission signal S from the remote control transmitter 2.2Receive. The appliance control unit 11 receives the reception signal S from the signal reception unit 12.3Is input, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.4And the lighting holding timer 19a starts a time-limited operation for a predetermined lighting holding time. Where time t11Then, the illuminance detection signal S of the illuminance sensor unit 134Is the first threshold L2Since it is brighter and outputs a high illuminance signal, the appliance control unit 11 turns off the illumination load unit 16 without turning it on.
[0039]
Then time t12Illuminance detection signal S of the illuminance sensor unit 13FourIs the first threshold L2When it becomes darker, time t12Until the time limit operation of the lighting hold timer 19a ends, the appliance control unit 11 lights the lighting load unit 16. Here, while the illumination load unit 16 is lit, the illuminance sensor control unit 14 sets the illuminance threshold value to the first threshold value L.2Brighter second threshold LThreeIt has been switched to.
[0040]
Thus, while the illumination load unit 16 is lit, the illuminance sensor control unit 14 sets the illuminance threshold value to the second threshold value L.ThreeSince the illumination load unit 16 is lit, the illuminance detection signal S of the illuminance sensor unit 13 is switched toFourIs the second threshold LThreeSince it becomes darker and the illuminance sensor unit 13 outputs a low illuminance signal, the appliance control unit 11 maintains the lighting state of the illumination load unit 16.
[0041]
By the way, even after the appliance control unit 11 turns on the illumination load unit 16, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.FourAre read sequentially and time t14Thus, for example, external light such as sunlight enters from the window, and the illuminance detection signal S of the illuminance sensor unit 13FourIs the second threshold LThreeIf it becomes brighter and outputs a high illuminance signal, the appliance control unit 11 turns off the illumination load unit 16. When the appliance control unit 11 turns off the illumination load unit 16, the illuminance sensor control unit 14 sets the illuminance threshold value to the second threshold value L.ThreeTo the first threshold L2It has returned to.
[0042]
Thus, even after the lighting load unit 16 is turned on, the appliance control unit 11 performs the illuminance detection signal S of the illuminance sensor unit 13.FourSince the lighting control of the lighting load unit 16 is performed based on the lighting load unit 16, the fixture control unit 11 turns off the lighting load unit 16 when external light or the like is incident after the lighting load unit 16 is turned on and becomes abnormally bright. Thus, it is possible to prevent the illumination load unit 16 from being turned on unnecessarily.
[0043]
In the present embodiment, the illuminance detection signal S of the illuminance sensor unit 13 is used.FourThe illuminance sensor control unit 14 uses the first and second threshold values L as2, LThreeTwo types of threshold values (when the illumination load unit 16 is turned on and when the illumination load unit 16 is turned off) are provided, but the illuminance threshold value is variable, and the illuminance depends on the ambient illumination after the illumination load unit 16 is turned on The sensor control unit 14 may set a plurality of illuminance threshold values. For example, the illuminance threshold value may be gradually reduced with the passage of time of the lighting hold timer 19a. The threshold value may be set continuously.
[0044]
  (Embodiment2)
  Embodiment1 and basic configuration 1, 2In the illuminating device, the transmission signal S from the remote control transmitter 2 is used as signal input means.1However, in the illumination device of this embodiment, as shown in FIG. 7, a timer signal is used as a signal input means at a predetermined time. The timer 19b, which is the second timer unit that generates the above, is used.
[0045]
For example, when the lighting load unit 16 is turned on / off by the remote control operation unit 24 of the remote control transmitter 2 or the human sensor unit 22 provided in the remote control transmitter 2 detects a person, the appliance control unit 11 In the lighting device that turns on the lighting load unit 16, the lighting control unit 11 controls lighting of the lighting load unit 16 when the human sensor unit 22 detects a person. Part 11 is set. For example, the time zone of each lighting mode is set in advance in the timer 19b, and the lighting mode is sequentially switched according to the timer signal of the timer 19b.
[0046]
As shown in FIG. 8, the case where there are two lighting modes of the normal “active mode” and the “greeting mode” as the lighting mode MD of the appliance control unit 11 will be described. Here, the lighting mode MD of the appliance control unit 11 is set to a time t by a preset timer.twenty one(For example, at 6 pm) the mode is switched from “active mode” to “greeting mode”.
[0047]
  First, in “active mode”Described in Basic Configuration 1Similar to the lighting device, the detection signal of the human sensor unit 22 provided in the remote control transmitter 2 and the illuminance detection signal S of the illuminance sensor unit 13 provided in the luminaire main body 1.4Based on the above, the appliance control unit 11 controls lighting of the illumination load unit 16. For example, time t19Thus, the human sensor 22 of the remote control transmitter 2 detects a person and the appliance controller 11 receives the received signal S of the signal receiver 12.3Is input, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.4And the lighting holding timer 19a starts a time-limited operation for a predetermined lighting holding time. At this time, the illuminance detection signal S of the illuminance sensor unit 134Is the threshold L1Since it is darker and outputs a low illuminance signal, the appliance control unit 11 fully lights up the lighting load unit 16 (for example, a dimming level of 100%) until the lighting holding timer 19a finishes the time limit operation. Let After that, if the signal receiver 12 does not receive the transmission signal of the remote control transmitter 2 by the end of the time limit operation of the lighting hold timer 19a, the time t when the time limit operation of the light holding timer 19a ends.20Thus, the appliance control unit 11 turns off the illumination load unit 16.
[0048]
On the other hand, in the “greeting mode”, the appliance control unit 11 controls the lighting load unit 16 at a certain dimming level (for example, a dimming level of 30%) even if the human sensor 22 does not detect a person. And the human sensor 22 detects the person, and the appliance controller 11 receives the signal S received from the signal receiver 12.ThreeIs input, the appliance control unit 11 turns on the lighting load unit 16 for a predetermined lighting holding time.
[0049]
Where time ttwenty oneWhen the timer signal of the timer 19b is input to the appliance control unit 11, the lighting mode MD of the appliance control unit 11 is switched from “active mode” to “greeting mode”, and the appliance control unit 11 sets the welcome mode. The welcome timer 19c, which limits the time, starts the time limit operation and the illuminance detection signal S of the illuminance sensor unit 13.FourAnd the operating state of the welcome timer 19c is read. And the appliance control part 11 is the illumination intensity detection signal S of the illumination intensity sensor part 13.FourAnd the operation state of the welcome timer 19c, and if the logical operation result is logical (1), the appliance control unit 11 dims the lighting load unit 16 and the logical operation result Is logic (0), the appliance control unit 11 turns off the illumination load unit 16. The illuminance detection signal S of the illuminance sensor unit 13FourIs the threshold L1If darker than logic (1), threshold L1If it is brighter, the logic is set to logic (0), the operation state of the welcome timer 19c is set to logic (1) if the time limit operation is in progress, and is set to logic (0) if the time limit operation has ended.
[0050]
By the way, time ttwenty oneThen, the illuminance detection signal S of the illuminance sensor unit 13FourIs the threshold LFourThe illuminance detection signal S of the illuminance sensor unit 13 is output by the appliance control unit 11.FourWhen the logical product with the operating state of the welcome timer 19c is obtained, the result of the logical product is logical (0), so the appliance control unit 11 turns off the lighting load unit 16 without turning it on. Thereafter, during the time limit operation of the welcome timer 19c, the appliance control unit 11 detects the illuminance detection signal S of the illuminance sensor unit 13.FourAre read sequentially, and the illuminance detection signal SFourAnd the operation state of the welcome timer 19c are calculated, and the time ttwenty twoThe illuminance detection signal S of the illuminance sensor unit 13FourIs the threshold L1When the signal becomes darker than the low illumination signal [logic (1)], the operation result of the logical product becomes logic (1), and the appliance control unit 11 makes the lighting load unit 16 dimmed.
[0051]
Then time ttwenty threeWhen the signal receiving unit 12 receives the transmission signal from the remote control transmitter 1, the appliance control unit 11 receives the received signal S of the signal receiving unit 12.ThreeBased on the time t at which the time limit operation of the lighting hold timer 19a ends.twenty fourUntil the lighting load unit 16 is turned on.
Time ttwenty fiveWhen the signal receiving unit 12 receives the transmission signal from the remote control transmitter 1, the instrument control unit 11 receives the received signal S of the signal receiving unit 12.ThreeThe lighting holding timer 19a is started based on the time limit, and the lighting load unit 16 is fully lit. Thereafter, until the time limit operation of the lighting hold timer 19a ends, the time t26, T27The signal receiver 12 receives the received signal S.ThreeEach time, the lighting holding timer 19a is reset, and the timing holding operation of the lighting holding time is started again from that time, so that the signal receiving unit 12 receives the received signal S.ThreeLast received time t27From the time t when the lighting holding timer 19a finishes the timed operation of the lighting holding time28Until this time, the appliance control unit 11 turns on the illumination load unit 16 completely.
[0052]
In the above-described embodiment, as a signal input means, a signal receiving unit 12 that receives a signal from the remote control transmitter 2, a human sensor unit that detects the presence or absence of a person, or a timer signal is generated at a predetermined time. Although the timer 19b is used, the setting operation unit 17 or the power supply unit 18 is used as a signal input means, and the appliance control unit 11 receives an operation signal from the setting operation unit 17 or a power-on signal from the power supply unit 18. Based on the illuminance detection signal of the illuminance sensor unit 13, the lighting load unit may be controlled to be lit. The signal input means may be a plurality of combinations among the signal receiving unit 12, the human sensor unit, the timer unit 19b, the setting operation unit 17, and the power supply unit 18.
