Abstract
【解決手段】 面状光源1と、それぞれ光が面状光源1を通じて出射される複数個の点状光源2とを備える。面状光源1の輝度が低い位置の点状光源2ほど、高い輝度で点灯される。これにより、面状光源1の輝度むらが点状光源2の光によって低減される。

Claims (2)
- 厚さ方向に通電されて発光する発光層と発光層を挟む透明な電極層とを有し厚さ方向に透光性を有する面状光源と、
面状光源を点灯させる第1点灯部と、
複数個の点状光源と、
各点状光源をそれぞれ点灯させる第2点灯部と、
点状光源の光を出射させる窓部を有し、点状光源と第1点灯部と第2点灯部とをそれぞれ収納するとともに、面状光源によって窓部が閉塞される形で面状光源を保持した器体とを備え、
第2点灯部は、面状光源の厚さ方向であって窓部の外側から見て面状光源の輝度が低い位置にある点状光源ほど高い輝度で点灯させることを特徴とする照明器具。 - 点状光源のうち少なくとも2個は、それぞれ面状光源の厚さ方向であって窓部の外側から見て面状光源の輝度が互いに同じとなる位置に配置されていることを特徴とする請求項1記載の照明器具。
