図7に示すように、表示面50の裏側に冷陰極ランプを用いた光源51を持つ内照式誘導灯であって、光源51の全長が表示面50の一辺例えば200mm以上400mm未満に対してほぼ同じ長さになっている。
【0003】
光源51は、表示面50の中央近傍に位置し、消防法に定められた光学特性を満足する。
【0004】
【発明が解決しようとする課題】
内照式誘導灯は、表示面50の一辺が従来200mmの誘導灯の2倍以上になる場合でも、一辺が200mmの誘導灯と同等以上の光学性能を満足するようにランプを設定する必要がある。

しかし、光源51の長さをより長くすると、取扱い時にランプが割れるおそれがあり、ランプメンテナンスを工事業者に依存するので、施工性を考慮すると現行の長さが限度である。
【0006】
一方、誘導灯の表示面には複数の絵柄があり、印刷部(緑色部)では光出力をロスしてしまう。
【0007】
したがって、この発明の目的は、一辺が400mm以上の大きさの表示面を有する誘導灯でも、一辺が200mm以上400mm未満の表示面を有する誘導灯に使用する光源を用いて、一辺が200mm以上400mm未満の表示面を有する誘導灯と同等以上の光学特性を満足することができる内照式誘導灯を提供することである。

【0022】
【発明の実施の形態】
この発明の第1の実施の形態を図1および図2により説明する。すなわち、この内照式誘導灯は、器具本体1と、点灯装置2、3と、光源4と、非常点灯用電池5と、透光性の表示板の表面に形成した表示面6とを有する。
【0023】
器具本体1は、横辺7と縦辺8の寸法比L、Hが略1対1である。実施の形態では一辺が400mmの正方形に形成し、表面に表示面6を設け、反射板は設けていない。
【0024】
四角形の表示面6は、図2に示すように、明色の透光部10と暗色の図柄部11とからなる図柄を備える。表示面6の一辺の長さは400mm以上であるが、最大の大きさは表示面として可能であり明るさも得られること等を考慮して決定される。実施の形態では表示面6の正方形の一辺の長さを略400mmとし、暗色は例えば緑色としている。
【0025】
光源4は、略直管状であり表示面6の裏側に配置され、器具本体1に取付けられている。光源4として、表示面6の横辺と縦辺の比が略1対1であり、かつ一辺の長さが200mm以上400mm未満の誘導灯に用いられる光源を複数用いている。さらに詳しくは光源4が表示面6の一辺の長さが略200mmの誘導灯に一灯用いられる例えば長さ220mmの冷陰極ランプを適用している。
【0026】
この略直管状の光源4の器具本体1の内部すなわち表示面6の裏側における配置は略鼓状をなし、表示面6の中心寄りに2灯のランプ4b、4cを互いに間隔をやや開けて略縦配置するとともに、これら2灯のランプ4b、4cを間にはさんで上下にそれぞれ1灯のランプ4a、4dを横配置している。すなわち、冷陰極ランプを水平方向に上下2本、その間に直角方向すなわち縦方向に左右2本と鼓状に配置する。これらの光源4の4灯の配置は略左右対称である。さらに光源4の縦配置したランプ4b、4cは表示面6を略3等分する位置にそれぞれ配置するとともに、横配置したランプ4a、4dは縦配置したランプ4a、4dに近接して配置している。実施の形態では一対のランプソケットを保持するソケット台9を互いにランプ4a〜4dの直交部分の一対の電極について共用し、全部で4個のソケット台9を器具本体1に取付けている。水平方向の上下2本のランプ4a、4dは外側の緑色の図柄部11よりも内側の白色の透光部10に多くかかるように配置し、図2に示すように、その上端からの距離L1 は100mm>L1 ≧80mm、表示面6の下端からの距離L2 は80mm>L2 ≧60mmとする。さらにその内側の緑色の図柄部11aにはランプ4a、4dが半分以上かからないように配置する。また直角方向の左右2本のランプ4b,4cは同じく外側の緑色の図柄部11よりも内側の白色の透光部10にかかるように、さらにその内側の緑色の図柄部11aにはランプが半分以上かからないように配置し、そのランプ4b,4c間距離Pを140mm≧P≧60mmとしている。
【0027】
点灯装置2、3は、光源4を点灯制御するもので、表示面6の左右側部に対応する位置の器具本体1の側部にそれぞれ設けている。これらの点灯装置2、3は2灯用点灯装置であり、光源4の縦配置と横配置の各1灯を配線し、各点灯装置2、3に接続される。
【0028】
非常灯用電池5は、商用電源の停電時に電力を供給するためのものであり、表示面6の下端部に相当する器具本体1の下端部に設けている。
【0029】
12は電源端子台、13は各配線である。
【0030】
この実施の形態によれば、一辺が200mm以上400mm未満の表示面を有する誘導灯に使用する光源4を複数用いることにより、200mm以上400mm未満の表示面を有する誘導灯と同等以上の光学特性を満足することができる誘導灯を、一辺が400mm以上の大きさの表示面6を有する誘導灯に適用することができる。
【0031】
光源4の略鼓形の配置により、誘導灯と同等以上の光学性能を満足する最小の本数と最適配置とを設定することができ、この配置によりランプの光出力を有効に使用でき、本数が最低数の4本となり、器具コストが抑えられる。ランプ本数が少ないため、ランプ交換時の手間が少なくてすみ、施工容易になる。
【0032】
この発明の第2の実施の形態を図3に示す。すなわち、第1の実施の形態において、反射板がある場合でありかつ、光源4のそれぞれ両端部の電極のうち互いに近接する部位の電極4a1 、4b1 、4c1 、4d1 を点灯装置2、3の電圧側として電圧2、3側の電極4a1 、4b1 、4c1 、4d1 に近接する点灯装置2、3と配線接続している。
【0033】
このため、図3(b)に示すようにランプ線の電圧線(高圧側)13aが短く接地線(低圧側)13bが長くなり、両者を分離できるので、高圧線13aと低圧線13bの接触による漏れ電流でのランプのちらつきや不点を防止できる。
【0034】
その他は第1の実施の形態と同様である。
【0035】
図4から図6は、表示面6の図柄の各種態様と、第1の実施の形態による光源4の配置を示す。第1の実施の形態の表示面6を光源4に対して、絵柄の中で最も緑色等の図柄部の面積が多いため、光が出にくくロスが多い絵柄を基準にしているので、図4から図6の明るさが悪くなることはない。
【0036】
【発明の効果】
請求項1記載の誘導灯によれば、一辺が200mm以上400mm未満の表示面を有する誘導灯に使用する光源を複数用いることにより、200mm以上400mm未満の表示面を有する誘導灯と同等以上の光学特性を満足することができる誘導灯を、一辺が400mm以上の大きさの表示面を有する誘導灯に適用することができる。
【0037】
