Description
前記入射部に対する光源側と異なる側に配されて、前記導光体から生じる光を拡散させる拡散カバーとを有しており、
前記拡散カバーは、前記導光体における前記入射部側を覆う板状基部と、外周部を前記板状基部に一体化させて前記導光体のその余の箇所を覆う環状部とを備えてなるものとした。
この場合さらに、前記導光体を、仮想の円の円弧に沿った弧状部と、前記仮想の円の外側においてこの仮想の円の中心を通る仮想の直線に平行をなす真直部と、両者間に位置されるコーナー部とを備えたものとすると共に、前記拡散カバーの仕切り部が、前記コーナー部に整合した形状の屈曲部を備えたものとしておくことが、この発明の好ましい態様の一つである。
すなわち、この実施の形態にあっては、前記導光体1は、前記弧状部11と、前記真直部12との間にコーナー部18を備えたものとなっている(図1)。
図13は、板状基部20の裏面20dに設けられた仕切り部20eが、板状基部20の真直辺20bに平行をなすリブ状をなす部分と、前記導光体1のコーナー部18に整合した形状を持った屈曲部20rとを備えるようにし、この仕切り部20eを導光体1の真直部12の内面及びコーナー部18の内面に接しさせるようにした拡散カバー2の第四例を示している。前記コーナー部18は入射部10より導光体1内に入射される光が集中し輝度が高くなるが、このコーナー部18を覆う屈曲部20rによってこのコーナー部18の光を効果的に拡散させることが可能となる。
なお、図16に示されるように、導光体1を弧状部11と、真直部12と、この真直部12の外側においてこの真直部12との間に空間sを開けてこの真直部12と平行をなすように配される外側真直部12’と、真直部12と外側真直部12’とをつなぐ外側腕部13’とを備えた態様とすると共に、外側真直部12’に入射部10を備えさせるようにした場合、導光体1の裏面15であって外側腕部12’と真直部12との間のコーナー部19にこのコーナー部19における前記空間s側の縁部を縁取るようにリブ19aを設けておくことが好ましい。このようにした場合、かかるリブ19aによって入射部10より導光体1内に入射される光を真直部12に効果的に回り込ませることが可能となる。
なお、2013年9月18日に出願された日本国特願2013−193367号の明細書、特許請求の範囲、図面及び要約書の全内容をここに引用し、本発明の明細書の開示として、取り入れるものである。
