Abstract
Description
(照明器具100)
図1を参照して、本実施の形態における照明器具100について説明する。図1は、照明器具100を示す斜視図(照明パネル10A~10Dの各々の発光面とは反対の裏面側から照明器具100を見た図)である。照明器具100は、照明パネル10A~10D、保持部材21,22、および、取付具31,32を備える。
以下、図2および図3を参照して、照明パネル10Aについて説明する。照明パネル10B~10Dは、照明パネル10Aと同様に構成される。照明パネル10B~10Dについては、その説明を繰り返さないものとする。
上述のとおり、取付具31,32は、筐体17の上面(照明パネル10Aとしての裏面10T)上において互いに間隔を空けて並んで設けられる。本実施の形態における取付具31,32は、互いに同様に構成される。以下、取付具32のみについて説明する。
図3においては、照明パネル10Aの発光面16と、照明パネル10B~10D(図1参照)の発光面16とが、同一平面上に位置している際の照明パネル10Aが図示される。照明パネル10Aのこの姿勢は、本発明における第1姿勢S1である。照明パネル10Aは、第1姿勢S1を形成している状態で、駆動回路40(図2参照)に駆動されることによって発光する。
照明パネル10Aは、外周部付近を押圧されることによって、第1姿勢S1から第2姿勢S2に容易に遷移する。照明パネル10Aは、第1姿勢S1を形成している状態においては、他の照明パネル10B,10D等によって囲まれており、照明パネル10B~10Dと同様に発光することができる。したがって照明器具100は、隙間なく密着するように配置された複数の照明パネル10A~10Dによって、効率よく均等に照明することができる。
図6に示すように、本実施の形態においては、照明パネル10A~10Cおよび他の複数の照明パネル(図示せず)が隣接するように配置される。照明パネル10A~10Cが保持部材21に取り付けられる際、各々の取付具31,32が、保持部材21に取り付けられる(矢印AR3参照)。保持部材21の表面には、複数の配線パターン24(電気接点)が互いに間隔を空けて設けられる。複数のうち両端に位置する配線パターン24は、駆動回路40に接続される。
図8に示すように、照明パネル10Aの裏面10T側の外周には、ストッパー部17Tが設けられていてもよい。ストッパー部17Tは、たとえば直方体状に形成され、照明パネル10Aの裏面10T上から外方に向かって膨出するように設けられる。
図10に示すように、本実施の形態における取付具31,32は、照明パネル10Aの裏面10Tのうちの、照明パネル10Aの保持部材21に対する回動の中心軸CCを挟んだ一方側17Mと他方側17Nとが互いに非対称となるように配置される。取付具31,32は、照明パネル10Aの回動の中心軸CCが照明パネル10Aの裏面10T上の側面近傍に偏るように配置される。
図11および図12に示すように、本実施の形態における取付具32は、受入れ部32Sが設けられた把持部33と、把持部33を支持する台座部34とから構成される。把持部33は、所定の剛性を有している。把持部33は、略C字状に形成され、受入れ部32Sを挟んで左右対称に形成される。本実施の形態における保持部材21には、受入れ部32Sの幅寸法に対応する、1対の切り欠き面23が設けられる。
図14に示すように、本実施の形態における取付具32は、全体としてT字状に構成される。取付具32は、棒状に形成された支持部35と、支持部35の先端部に取り付けられた棒状の差込部36とから構成される。支持部35の後端部に、照明パネル(図示せず)が取り付けられる。
