Abstract
Description
(LED灯具の保持状態及び半保持状態)
本実施の形態に係るLED照明器具は、LED素子を用いたLED灯具では、従来の蛍光管に比べて電源接続用プラグを備える位置の制約が少ない点に着目してなされたものであって、一方の端部に電源接続用プラグ兼保持箇所を備えるとともに他方の端部に保持箇所を備え、半保持状態を実現するLED灯具を備えたLED照明器具を提供する。
LED灯具140の左端部150(端部)を保持する左保持部120は、図1に示すように、J字状形状の左保持体120j、及びJ字状形状の開口を閉じるように配置された左保持留め具121、122で構成されており、左保持留め具121は左保持留め具122を支点にしてバネの力により左保持体120jに圧着されている。LED灯具140の着脱時には、左保持留め具121を押し込んで左保持体120jと左保持留め具122の間に開口を作り、保持箇所(端部)である左端部150をはずす。左端部150は図2に示すようにループ状になっている。
図3Bは、LED照明器具100の保持状態における右側面図であって、LED灯具140の右端部(端部)の保持箇所であるプラグ160の保持状態を示している。保持具天板111に連結された右保持部130は下(床面側)からプラグ160が挿入できるようプラグ挿入口136が設けられており、またその内部にはスプリング機構があって挿入されたプラグ160を強く圧着・保持する。
図4Aは、LED灯具140を保持具110から取り外す作業を示す正面図である。図5は、LED灯具140の取り外しを行うときの作業棒181とLED灯具140との相関関係を模式的に示す右側面図である。
LED灯具140は、図1および図2に示したように、ベース部146に複数のLED素子145が取り付けられたものである。LED素子145は、LED素子145を保護し、必要に応じて配光を制御するため、透明又は半透明のカバー148で覆われている。カバー148はレンズまたはプリズムの機能を兼ねるものであってもよい。ベース部146の両端につながる左補強部141、右補強部142は、補強強度を向上させ、カバー148の保持を容易にするため、円柱状になっている。
LED素子145としては、青色LEDチップが1つのパッケージに1個または数個配置され、青色LEDチップが発する光によって励起されて緑色、赤色の光を発する蛍光体を混ぜた樹脂によって樹脂封止されたものを用いた。LED素子145として、青色LED、緑色LED,赤色LEDチップが組み合わさったもの(マルチカラーLED)を用いることもでき、その場合には、照明色を変化させることもできるため高付加価値のLED照明器具になる。
図6Aは、LED灯具140よりも幅広のLED灯具140Bを用いた場合の下面図である。図6Bは、右側面図である。基本的な構成は、図1、図2に示したLED照明器具100、LED灯具140と同様であり、概略を示す。
実施の形態2のLED照明器具200を、図7から図11に基づいて説明する。図中の200番台の部材は特に説明がない場合は下二桁が同じ100番台の部材に対応している。
実施の形態3のLED照明器具300を、図12から図16に基づいて説明する。図中の300番台の部材は特に説明がない場合は下二桁が同じ100番台の部材に対応している。
実施の形態4のLED照明器具400を、図17から図19に基づいて説明する。図中の400番台の部材は特に説明がない場合は下二桁が同じ100番台の部材に対応している。
実施の形態5のLED照明器具500を、図20および図21に基づいて説明する。図中の500番台の部材は特に説明がない場合は下二桁が同じ100番台の部材に対応している。
実施の形態6のLED照明器具600を、図22から図25に基づいて説明する。図中の600番台の部材は特に説明がない場合は下二桁が同じ100番台の部材に対応している。
保持具610の左保持部620は、ループ状になっており、LED灯具640のフック状の左端部650が掛かるようになっている。従って、左端部650だけを掛けた状態で、半保持状態となる。
右保持部630は、保持具天板611からLED灯具640側に突出せずに、天井側に配置されるように保持具天板611の上面側に突出している。プラグ660は保持箇所を兼ねており、プラグ660をプラグ挿入口636(図23参照)へ差し込むことにより、LED灯具640が保持される。
保持具天板611は、例えば鉄を主成分とする磁性体で構成されており、LED灯具640に配置された磁石649が保持具天板611に吸着する。そのため、磁石649に吸着する保持具天板611自体が保持部610の主要な機能を備えている。
図25は、保持具610に、LED灯具640よりも幅狭なLED灯具640Bを3個取り付けた例である。この場合には、図24で使われなかった右保持部630B、630Cが用いられる。この保持具610を用いれば、幅狭なLED灯具640Bを1個、2個、3個取り付ける場合と幅広なLED灯具640を取り付ける場合などの使い分けが実現でき、必要な照度に対して柔軟な組合せが可能となる。
各実施の形態において端部とは中央よりも相対的に端に近い部分であって、LED灯具を保持する部分の近傍を指しており、LED灯具の最も端の部分という意味ではない。
