Description

【０００１】
【発明の属する技術分野】本発明は、制御対象の制御状態をリモコン操作により切り替えるリモコン送信器及び照明器具に関する。
【０００２】
【従来の技術】制御対象である照明器具の点灯状態の切り替えは、壁スイッチやプルスイッチを用いるものが多いが、リモコン送信器を用いてリモコン操作により点灯状態を切り替えるものも増えている。
【０００３】
リモコン送信器は、例えば、リモコン信号をＬＥＤ（Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）により光信号で出射し、その光信号を照明器具のリモコン信号受信部に受光させることにより照明器具の点灯状態の切り替えを行なうものである。
【０００４】
このようなリモコン送信器としては、特開平１１−２８８７８７号公報に、リモコンの本体ケースの前端部に前方向に指向された第一のＬＥＤと斜め方向に指向された第二のＬＥＤとを設けたリモコン送信器が提案されている。これにより、リモコン送信器を手に持って使用するときには、リモコン送信器の前端部を天井に設置された照明器具に対して向けることにより第一のＬＥＤが有効となり、リモコン送信器を壁に掛けて使用する場合には、第二のＬＥＤが有効となるとされている。
【０００５】
また、リモコン送信器の別の従来例としては、リモコン送信器の前端部と、操作ボタンが設けられたリモコン送信器の側面部とにそれぞれ一つのＬＥＤを設けているものがある。これにより、リモコン送信器が出射する光信号の届く範囲を広げている。
【０００６】
また、近年では、点灯予約や消灯予約などの予約機能が付与されているリモコン送信器が登場している。これらの機能は、リモコン送信器で予め設定した時間が経過した場合や予め設定した時刻になると、リモコン送信器が自動的に点灯や消灯の光信号を射出するものである。
【０００７】
【発明が解決しようとする課題】リモコン送信器は、屋内の不特定な場所に置かれた状態であっても光信号によって照明器具の制御を行ないやすいことが好ましいが、上述した従来のリモコン送信器では達成されていない。また、予約機能が付与されたリモコン送信器は、必ずしも手に把持されて使用されるということではなく、照明器具が設置されている屋内の不特定な場所に置かれた状態で使用されることもあるので、予約機能を有効に機能させるためにもリモコン送信器の光信号の届く範囲をさらに拡大することが望まれている。
【０００８】
本発明の目的は、リモコン送信器の光信号の届く範囲を拡大することである。
【０００９】
【課題を解決するための手段】請求項１記載の発明のリモコン送信器は、筐体形状の本体ケースと；前記本体ケースの内部に設けられ、リモコン信号を発生させるリモコン信号発生部と；前記本体ケースの外周部に設けられ、前記リモコン信号を発生させるために操作される操作部と；前記本体ケースの外周部の一面側に設けられ前記リモコン信号を光信号で出射する第一の光源と；前記本体ケースの外周部の他面側に設けられ前記リモコン信号を光信号で出射する第二の光源と；前記本体ケースの外周部の前記他面側に取り付けられ前記リモコン信号を前記第二の光源の光軸とは異なる向きの光軸の光信号で出射する第三の光源と；を備える。
【００１０】
ここで、第二の光源と第三の光源とは、第一の光源が設けられる本体ケースの外周部の一面側と異なる複数の他面側に設けられていてもよい。
【００１１】
したがって、リモコン信号である光信号が、第一の光源によって本体ケースの一面側から出射されるとともに、第二の光源と第三の光源とによって本体ケースの他面側から出射され、このとき、第二の光源と第三の光源とから出射される光信号の光軸が互いに異なる角度であるので、広い範囲に光信号が出射される。
【００１２】
ここで、本体ケースの外周部の第一の光源が設けられている一面側に、リモコン信号を第一の光源の光軸とは異なる向きの光軸の光信号で出射する光源をさらに設けてもよい。これにより、さらに、広い範囲に光信号を出射することが可能となる。
【００１３】
また、第一の光源、第二の光源及び第三の光源を、それぞれ複数設けることにより、同一方向に出射される光信号の光強度が強くなり、光信号をリモコン信号受信部に確実に届けることが可能となる。
【００１４】
請求項２記載の発明は、請求項１記載のリモコン送信器において、前記第二の光源と前記第三の光源とは、互いに異なる放射角度の光を出射する。
【００１５】
したがって、第二の光源と第三の光源とのそれぞれの光の放射角度をそれぞれ光軸の向きによって設定することにより、光信号の届く範囲をリモコン信号受信部に対して最適な範囲とすることが可能となる。
【００１６】
請求項３記載の発明の照明器具は、請求項１又は２記載のリモコン送信器と；前記リモコン送信器から送信された前記光信号を受信するリモコン信号受信部と受信した光信号に応じて点灯状態を切り替えられる照明手段とを有する照明器具本体と；を備える。

【００２４】
３個の第一のＬＥＤ１１は、本体ケース７の外周部の前面７ｂ側において、左右方向に配列されている。第一のＬＥＤ１１は、それらの光軸が本体ケース７の前後方向と平行になるように設けられ、第一のＬＥＤ１１は、本体ケース７の前面７ｂ側から本体ケース７の外に向けて赤外線信号を出射する。
【００２５】
２個の第二のＬＥＤ１２は、本体ケース７の外周部の表面７ａ側の前端部において左右方向に配列され、その内側に２個の第三のＬＥＤ１３が左右方向に配列されている。第二のＬＥＤ１２は、それらの光軸が本体ケース７の表裏方向（本体ケース７の前後方向に垂直な方向）から前方に所定角度α１傾くように設けられ、本体ケース７の表面７ａ側から本体ケース７の外に向けて赤外線信号を出射する。なお、本実施の形態ではα１＝１５度に設定されている。これらの第二のＬＥＤ１２は、光の放射角度が広角に設定されているいわゆる広角タイプであり、本実施の形態では、光の放射角度は約３５度に設定されている。
【００２６】
第三のＬＥＤ１３は、本体ケース７の外周部の表面７ａにおいて、それらの光軸が本体ケース７の表裏方向から前方に所定角度α２傾くように設けられ、本体ケース７の表面７ａ側から本体ケース７の外へ向けて赤外線信号を出射する。なお、本実施の形態ではα２＝３０度に設定されている。これらの第三のＬＥＤ１３は、光の放射角度が狭角に設定されているいわゆる狭角タイプであり、本実施の形態では、光の放射角度が約２０度に設定されている。
【００２７】
リモコン用スタンド４は、図４に示すように、リモコン送信器３を立てた状態、具体的にはリモコン用スタンド４の設置面１４の垂直方向に対してリモコン送信器３の前端を所定角度α３傾けた状態でリモコン送信器３を保持する。なお、本実施の形態ではα３＝１０度に設定されている。
【００２８】
このような構成において、リモコン送信器３の操作ボタン８を操作することにより、その操作ボタン８に応じたリモコン信号が、第一のＬＥＤ１１、第二のＬＥＤ１２及び第三のＬＥＤ１３により、赤外線信号で出射（送信）される。操作された操作ボタン８が点灯予約や消灯予約のボタンであるときには、リモコン送信器３で予め設定した時間が経過した場合や予め設定した時刻になると、リモコン送信器３が自動的に点灯や消灯の赤外線信号を出射する。そして、リモコン送信器３から出射された赤外線信号を照明器具のリモコン信号受信部６が受光（受信）することにより、その赤外線信号に応じて蛍光灯５の点灯状態が切り替えられる。
【００２９】
ここで、リモコン用スタンド４に保持されたリモコン送信器３が出射する赤外線信号が届く範囲について、図１、図５、図６、図７及び図８に基づいて説明する。
【００３０】
リモコン送信器３を、その表面７ａ側が照明器具に向けられた状態でリモコン用スタンド４に保持された状態で、第一の設置位置ａ〜第五の設置位置ｅに設置する。ここで、設置位置ａは、照明器具の直下の位置、第二の設置位置ｂ〜第五の設置位置ｅは、第二の設置位置ｂから第五の設置位置ｅに向かうに従い照明器具の直下から徐々に離れる位置である。
【００３１】
第一の設置位置ａでは、図１に示すように、第一のＬＥＤ１１が出射する赤外線信号が届く範囲１５の内側に照明器具本体２のリモコン信号受信部６が位置することになり、第一のＬＥＤ１１が出射する赤外線信号が有効となる。
【００３２】
第二の設置位置ｂでは、図５に示すように、第二のＬＥＤ１２が出射する赤外線信号が届く範囲１６の内側に照明器具本体２のリモコン信号受信部６が位置することになり、第二のＬＥＤ１２が出射する赤外線信号が有効となる。第三の設置位置ｃでは、図６に示すように、第二のＬＥＤ１２が出射する赤外線信号が届く範囲１６の内側に照明器具本体２のリモコン信号受信部６が位置することになり、第二のＬＥＤ１２が出射する赤外線信号が有効となる。
【００３３】
第四の設置位置ｄでは、図７に示すように、第三のＬＥＤ１３が出射する赤外線信号が届く範囲１７の内側に照明器具本体２のリモコン信号受信部６が位置することになり、第三のＬＥＤ１３が出射する赤外線信号が有効となる。第五の設置位置ｅでは、図８に示すように、第三のＬＥＤ１３が出射する赤外線信号が届く範囲１７の内側に照明器具本体２のリモコン信号受信部６が位置することになり、第三のＬＥＤ１３が出射する赤外線信号が有効となる。
【００３４】
このように、本実施の形態では、リモコン信号である赤外線信号が、第一のＬＥＤ１１によって本体ケース７の前面７ｂ側から出射されるとともに、第二のＬＥＤ１２と第三のＬＥＤ１３とによって本体ケース７の表面７ａ側から出射され、このとき、第二のＬＥＤ１２と第三のＬＥＤ１３から出射される光信号の光軸が互いに異なる角度であるので、広い範囲に光信号を出射することができる。
【００３５】
また、第二のＬＥＤ１２と第三のＬＥＤ１３とが互いに異なる放射角度の光を出射するので、第二のＬＥＤ１２と第三のＬＥＤ１３とのそれぞれの光の放射角度をそれぞれの光軸の向きを考慮して設定することにより、光信号の届く範囲をリモコン信号受信部６に対して最適な範囲とすることができる。
【００３６】
また、本実施の形態では、第一のＬＥＤ１１、第二のＬＥＤ１２及び第三のＬＥＤ１３がそれぞれ複数設けられているので、同一方向に出射される光信号の光強度が強くなり、照明器具から赤外線が放出されている状態においても、赤外線光信号を照明器具のリモコン信号受信部６に確実に届けることができる。
