Abstract
Description
本発明の一実施形態に係る照明装置について、図1乃至6を参照して説明する。図1乃至6に示すように、本実施形態の照明装置1は、有機EL素子を用いた平面状の発光パネル5を収容するケース20を有する光源部2と、発光パネル5を点灯制御するための(プリント)回路基板8を収容するハウジング30を有する装着部3と、を備える。図1の例では、ハウジング30はプレート枠であり、回路基板8はプレート枠30内に保持されている。光源部2のケース20には、発光パネル5と共に、(プリント)配線基板6が収容されている。また、光源部2は、装着部3と対向する面(背面)に、装着部3と係合するための複数(2つ)の爪部21と、配線基板6と装着部3の回路基板8とを電気的に接続するための複数(2つ)の端子部4と、を備える。端子部4は、光源部2の回路基板8から突設され、ケース20に形成された複数(2つ)の溝部23を通して、装着部3側に露出している。また、装着部3は、光源部2の爪部21と係合するように形成される複数(2つ)の保持部31を備え、この保持部31によって光源部2を着脱自在とすることができる。
ところで、上記文献2に記載の照明装置においては、凹部が、発光パネルの発光面側の一部に被るので、発光面側に非発光領域(発光しない領域)が生じてしまう。そのため、例えば、複数の発光パネルを並設する場合、凹部の箇所が非発光となり、発光面の大きな照明装置を組むことができない。また、上記文献3に記載の照明器具おいても、筐体の一部が発光パネルの発光面側の一部に被るので、非発光領域が生じてしまう。更に、この種の照明装置において、発光パネルの装着を容易にすれば、発光パネルの保持が不安定になり、逆に、発光パネルの保持を強固にすれば、脱着が困難になることがあった。
次に、本発明の第3実施形態に係る照明装置について、図13A及び13Bを参照して説明する。本実施形態の照明装置1は、光源部2の係合部21aが、U字形状のフック部材として形成され、装着部3の被係合部31aが軸部材として形成されているものである。つまり、U字形状の係合部21aが、軸状の被係合部31aに引っ掛かることにより、被係合部31aを回動軸として、光源部2が装着部3に対して回動自在とされる。本例において、係合部21a及び被係合部31aは、光源部2及び装着部3の各一辺の両端部に、夫々2箇所設けられている。また、係合部21a及び被係合部31aが設けられた辺と対峙する辺には、保持部21b及び被保持部31bが設けられる。本例では、光源部2及び装着部3における上記辺の中央部に、夫々1箇所設けられている。
