【0026】
【発明の実施の形態】
以下、本発明にかかる発光装置付き建材の実施の一形態について、図面(図1乃至図5)を参酌しながら説明する。この実施例では、発光装置付き手摺りについて説明するが、発光装置を組み込む建材は手摺りに限定されるものではなく、手摺り以外に屋内又は屋外に設置される棒状の建材についても同様の発光装置を採用することが可能である。
【0027】
図1は、発光装置付き手摺りの一例を示す正面図である。また、図2は、発光装置付き手摺りの一例を示す断面図である。
【0028】
図1に示すように、10は手摺り本体、11a・11bは手摺り端部、20a・20bはLED、22はアクリル樹脂製導光体、23は光拡散部である。手摺り本体10は、その背面の側面部に配した取り付け部13により壁等に固定させて取り付けられる。
【0029】
手摺り本体10には、図1及び図2に示すように、アクリル樹脂製導光体22が長手方向の正面の側面部に形成された溝に挿着されている。また、手摺り本体10の両端には、手摺り端部11a・11bが取り付けられ、その手摺り端部11a・11bには、それぞれLED20a・20bが内設されている。LED20a・20bは、図1に示すように、アクリル樹脂製導光体22の両端に臨ませて取り付けられる。
【0030】
光拡散部23は、図1に示すように、アクリル樹脂製導光体22の外側面の上部又は底部に所定の間隔をおいて形成された溝又は凹部から構成される。このような光拡散部23を設けることにより、アクリル樹脂製導光体22の内部にLED20a・20bの光を透過させたとき、光拡散部23により透過光が拡散されるため、光拡散部23の周辺の輝度を高める効果がある。
【0031】
図3は、発光装置付き手摺りの光拡散部の一例を示す正面図である。
【0032】
光拡散部23の形状は、図1に示すような直線状の溝又は凹部に限定されず、格子状の溝又は凹部(図3(a)参照)、円形状の溝又は凹部(図3(b)参照)、菱形状の溝又は凹部(図3(c)参照)を適宜選択することができる。
【0033】
図4は、発光装置を作動させる構成の一例を示すブロック図である。
【0034】
図4に示すように、20は手摺り端部11に内設されるLED、30は光検知センサー、31は人検知センサー、32は制御回路、33は太陽電池、34はバッテリー、35はAC電源、36は変換機、37は通電センサーである。
【0035】
先ず、発光装置の基本的な作動手順について説明する。
【0036】
光検知センサー30は、屋内又は屋外の所定個所に設置されており、光検知センサー30の周囲の明暗を検知して光検知信号を制御回路32に送信する。制御回路32において、周囲が暗いとの検知信号を受信した場合、発光装置を作動可能な状態になるように自動的に切り替えられる。これにより、光検知センサー30の周囲が暗い場合において人検知センサー31が人物を検知すると、制御回路32からの指示によりLED20が点灯する。このLED20の点灯時間は、適宜調整することが可能である。
【0037】
なお、光検知センサー30は、本発明にかかる発光装置の作動に関して必須の構成ではなく、周囲が明るい場合において作動しても問題がないと考えられるため、省略することが可能である。
【0038】
次に、発光装置を作動させる電源について説明する。
【0039】
図4に示すように、発光装置を作動させる電源として、太陽電池33とAC電源35を併用した蓄電方式を採用することができる。
【0040】
太陽電池33は小型のソーラーパネル等の発電装置からなり、太陽電池33により発電された電力は、バッテリー34に充電される。なお、バッテリー34には、充電残量を表示するランプを設けておくことが好ましい。
【0041】
また、AC電源35を使用する場合には、電力が変換機36を介してバッテリー34に充電される。バッテリー34の充電残量が十分にある場合は、バッテリー34から制御回路32、光検知センサー30、人検知センサー31、発光装置に対して電気が供給されるが、バッテリー34の充電残量が少ない場合には、AC電源35から変換機36を介して制御回路32、光検知センサー30、人検知センサー31、発光装置に対して電気が直接供給されるようにしておく。
【0042】
さらに、AC電源35を主電源として使用する場合には、図4に示すように、AC電源35の通電状態(ON/OFF)を検知する通電センサー37を設けるとともに、災害等の非常事態においてAC電源35からの通電がOFFになった時に通電がONになるまでの間にLED20を点滅させる作動回路(図示省略)を制御回路32に設けることができる。この場合、災害等の非常事態において停電になったとき、太陽電池33により発電された電力を充電したバッテリー34から電気が供給されてLED20を点滅させることにより、発光装置を組み込んだ手摺り等の建材及びその周辺の視認性を高めて安全性を確保することができる。
【0043】
最後に、発光装置付き手摺りの使用方法について説明する。
【0044】
図5は、発光装置付き手摺りを階段に取り付けて使用する状態を示す説明図である。
【0045】
図5に示すように、Aは屋外又は屋内の階段であり、手摺り本体10は階段Aの壁等に設置される。光検知センサー30a・30b及び人検知センサー31a・31bは、階段の上部付近と下部付近にそれぞれ設置される。
【0046】
光検知センサー30a・30bは周囲の明暗を検知し、周囲が暗い場合には、発光装置が作動可能な状態になり、人検知センサー31a・31bが人物を検知すると、上述したように制御回路32からの指示により手摺り端部11a・11bに内設されたLED20a・20bが点灯する。このとき、アクリル樹脂製導光体22の内部にLED20a・20bの光が透過するとともに、光拡散部23により透過光が拡散されて、当該光拡散部23の周辺の輝度が高められる。
【0047】
次に、本発明にかかる住宅設備用発光装置の実施の一形態について、図面(図6乃至図12)を参酌しながら説明する。
【0048】
図6は、住宅設備用発光装置の一例を示す分解斜視図である。
【0049】
図6に示すように、50は階段周辺などの住宅設備に取り付ける住宅設備用発光装置、51は透明アクリル樹脂製のT字型導光棒、54は乳白色半透明アクリル樹脂製のコ字型反射枠、60a・60bはLED、62a・62bは乳白色半透明アクリル樹脂製の蓋である。
【0050】
T字型導光棒51は、その下部両側面及び底面がコ字型反射枠54の内側面に嵌め合わせて取り付けられるように成形されている。また、T字型導光棒51がコ字型反射枠54から容易に外れないようにするため、T字型導光棒51の下部側面のいずれか一方に凸部52を形成し、それに対向するコ字型反射枠54の内側面に凹部56を形成しておくことが好ましい(図8乃至図11参照)。
【0051】
また、T字型導光棒51の底面には、図7に示すように、溝又は凹部から構成される光拡散部53a〜fが形成されている。このような光拡散部53a〜fを設けることにより、T字型導光棒51の内部にLED60a・60bの光を透過させたとき、光拡散部53a〜fにより透過光が拡散されるため、光拡散部53の周辺の輝度を高める効果がある。この光拡散部53は、T字型導光棒51の少なくとも底面中央部(53c及び53d)に設けておくことにより、特に階段に取り付けた場合、中央部の位置関係が明確となり、階段昇降時の危険性を回避できる。
【0052】
また、T字型導光棒51の上面形状は、図8及び図10に示すように、住宅設備用発光装置50を階段などに取り付けた際に、その取付表面がフラットになるように形成されているもの以外に、図9及び図11に示すように、円弧状に形成したものを採用することができる。このように、T字型導光棒51の上面形状を円弧状に形成したものを採用すると、円弧状の表面が周囲よりも突出するため、夜間における視認性を高める効果がある。
【0053】
コ字型反射枠54は、図6に示すように、T字型導光棒51よりも若干長く形成されており、コ字型反射枠54の両端部にLED60a・60bが取り付けられる。また、コ字型反射枠54の両端部のLED60a・60bが取り付けられる位置に対向して、配線61a・61bを挿通する一対の孔55a・55bが設けられている。また、コ字型反射枠54の両端部の上面開口部を閉鎖する半透明アクリル樹脂製の蓋62a・62bが設けられている。
【0054】
また、コ字型反射枠54に、LED60a・60bの同電極を接続する配線57a・57bをコ字型反射枠54と一体に成形することができる(図10及び図11参照)。この場合、LED60a・60bと電源との接続を1箇所にまとめることができるので、配線61a又は61bのいずれか一方を省略することができる。
【0055】
ここで、住宅設備用発光装置50の組み立て手順の一例を説明する。
【0056】
図6に示す各部材を準備した後、T字型導光棒51をコ字型反射枠54に嵌め込んで取付け、そのコ字型反射枠54の両端部にLED60a・60bを載置しT字型導光棒51の両端部に臨ませて接着剤等により固定する。その後、LED60a・60bの電極と電源に接続された配線61a・61bとを接続し、蓋62a・62bをコ字型反射枠54の両端部の上面開口部に取り付け、この状態の下で、シリコンをLED60a・60bの周囲に充填する。このように、シリコンを充填することにより、防水及び絶縁の効果が得られる。
【0057】
また、住宅設備用発光装置の基本的な作動手順及び作動させる電源については、上述した発光装置付き建材の実施例と同様である。
【0058】
最後に、住宅設備用発光装置の使用方法について説明する。
【0059】
図12は、住宅設備用発光装置を階段に取り付けて使用する状態を示す説明図である。
【0060】
図12に示すように、Aは階段であり、住宅設備用発光装置50は階段Aの各踏み板の先端部分に取り付けられる。人検知センサー(図示省略)は、階段の上部付近と下部付近と天井にそれぞれ設置されている。この実施例では、住宅設備用発光装置50を階段Aに取り付けた場合について説明するが、住宅設備用発光装置50を取り付ける箇所は階段の踏み板に限定されるものではなく、階段周囲の側壁、玄関や室内の床面又は側壁などにも取り付けることができる。
【0061】
人検知センサーが人物を検知すると、上述したように制御回路32からの指示によりLED60a・60bが点灯する。このとき、住宅設備用発光装置50の両端部が明るく光るとともに、T字型導光棒51の内部にLED60a・60bの光が透過してコ字型反射枠54により光が反射されることも相俟って住宅設備用発光装置50の両端部から中央部にかけても全体が光る。更には、光拡散部53により透過光が拡散されて、当該光拡散部53の周辺の輝度が高められる。
【0062】
【発明の効果】
以上のように、本発明にかかる発光装置付き建材によれば、棒状の建材に組み込むことができる発光装置をLEDとアクリル樹脂製導光体により構成したので、屋内又は屋内における夜間等の安全性を高めることができ、部品コスト・製造コストの低減を図り、かつ、配線工事等の作業の手間を省くことが可能となる。
【0063】
また、本発明にかかる住宅設備用発光装置によれば、階段周辺などの住宅設備に取り付ける発光装置をLEDとアクリル樹脂製導光体により構成したので、住宅設備について夜間等の安全性を高めることができ、部品コスト・製造コストの低減を図り、かつ、配線工事等の作業の手間を省くことが可能となる。
【0064】
また、発光装置を作動させる各センサーを備えることにより、必要時にのみLEDを点灯させることができるばかりでなく、発光装置及び各センサーを作動させる電源として、太陽電池とAC電源を併用した蓄電方式を採用したことにより、省エネルギー化を図ることが可能となる。

Further, when the AC power supply 35 is used as a main power supply, as shown in FIG. 4, a power supply sensor 37 for detecting the power supply state (ON / OFF) of the AC power supply 35 is provided, and the AC power supply 35 is used in an emergency such as a disaster. When the power supply from the power supply 35 is turned off, the control circuit 32 may be provided with an operation circuit (not shown) for blinking the LED 20 until the power supply is turned on. In this case, when a power failure occurs in an emergency such as a disaster, electricity is supplied from the battery 34 charged with the power generated by the solar cell 33 to blink the LED 20, so that a handrail or the like incorporating a light emitting device can be used. Visibility of the building material and its surroundings can be enhanced to ensure safety.
