Claims (8)
- 光源の入射光を入射端面に供給して導光する合成樹脂製の導光板と、該導光板の裏面に配置したベース板と、導光板の入射端面とベース板の裏面端部に亘るように該ベース板を挟んで配置した光源ホルダーを備え、該光源ホルダーを、入射端面側に光透過口を有する光源収納部と、該光源収納部からベース板の裏面に向けて起立した起立板を具備して断面L字状に一体に形成し、該光源ホルダーの上記光源収納部に光源を収納して光透過口から入射端面に入射光を供給自在とし且つ上記ベース板を挟んだ導光板と起立板を該ベース板に対して可動として上記起立板を導光板に固定することによって、該光源ホルダーを導光板の熱膨張収縮に対して独立して移動自在としてなることを特徴とするディスプレー、サイン、面照明体等の導光パネル。
- 上記導光板に対する起立板の固定を、起立板側から導光板に対する金具固定によって行なうとともに該金具固定をベース板に配置した導光板の熱膨張方向に該金具を可動とする貫通孔乃至貫通溝を介して行なってなることを特徴とする請求項1に記載のディスプレー、サイン、面照明体等の導光パネル。
- 上記起立板の固定位置を、導光板のコーナー近傍位置とするとともに該起立板を該コーナー近傍位置から斜め方向に可動とすることによって、光源ホルダーを導光板のコーナー近傍位置の熱膨張収縮に対して上記独立した移動を自在としてなることを特徴とする請求項1又は2に記載のディスプレー、サイン、面照明体等の導光パネル。
- 上記導光板コーナー近傍位置の起立板の一体的固定を、起立板に斜め方向に向けた長孔を配置し、該長孔から導光板に対する金具固定によって行ってなることを特徴とする請求項3に記載のディスプレー、サイン、面照明体等の導光パネル。
- 上記金具固定を、導光板に埋込設置したインサートナットに起立板側からのボルトを螺入して行なってなることを特徴とする請求項1、2、3又は4に記載の電食看板、サイン、面照明体等の導光パネル。
- 上記光源ホルダーを、入射端面側において端部を被覆するように表面に向けて起立した装飾板を備えた断面U字状とすることによって額縁兼用のものとしてなることを特徴とする請求項1、2、3、4又は5に記載のディスプレー、サイン、面照明体等の導光パネル。
- 上記光源ホルダーの外側に、導光パネルの入射端面側の端部を被覆する断面U字状の額縁を備え、該額縁裏面の裏面起立板を上記光源ホルダーの起立板と同時に導光板に金具固定することによって光源ホルダーとともに該額縁を導光板の熱膨張収縮に対して上記独立した移動を自在としてなることを特徴とする請求項1、2、3、4、5又は6に記載のディスプレー、サイン、面照明等の導光パネル。
- 上記光源を、LEDチップを基板長手方向に直列に配置したLEDユニットとし、上記光源ホルダーの光源収納部を、光透過口を開口溝とする断面C字状に形成し、該開口溝両端の対向突条に導光板端部を対接自在とするとともに上記LEDチップ間の基板上に該対向突条間に亘るように配置して該基板と対向突条間にスペーサーを保持することによって光源ホルダーの光源収納部に該LEDユニットを収納配置してなることを特徴とする請求項1、2、3、4、5、6又は7に記載のディスプレー、サイン、面照明体等の導光パネル。
