PROBLEM TO BE SOLVED: To complement luminosity shortage, luminosity irregularity or the like caused by a weakly-lighting light source, in luminaire including a light source module containing a plurality of light sources.SOLUTION: Luminaire 2 includes a light source module 22 formed by mounting matrically a plurality of light sources on a substrate, a driving circuit 30 for supplying power individually to each light source, and a control part 6 for controlling the lighting state of each light source respectively through the driving circuit 30. The control part 6 includes a detection part 6a for detecting a weakly-lighting light source having lower luminosity than other light sources from among the plurality of light sources, and an adjustment part 6b for allowing a light source adjacent to the weakly-lighting light source to emit light with higher luminosity than other light sources.SELECTED DRAWING: Figure 4
【課題】複数の光源を含む光源モジュールを備えた照明装置において、弱点灯光源に起因する光度不足、光度むら等を補完する。【解決手段】照明装置2は、基板上に複数の光源が行列状に実装されてなる光源モジュール22と、各光源に個別に電力供給する駆動回路30と、駆動回路30を介して各光源の点灯状態をそれぞれ制御する制御部6とを備える。制御部6は、複数の光源のうちの他の光源よりも光度が低い弱点灯光源を検出する検出部6aと、弱点灯光源に隣接する光源を他の光源よりも高光度で発光させる調整部6bとを含む。【選択図】図4
