LUMINAIRE

To sufficiently secure a fire spread distance and an insulation distance.SOLUTION: A luminaire 1 comprises: an appliance body 10; a board 110 being placed on the appliance body 10, and comprising an outer peripheral region 140 and an inner peripheral region 150 different from each other in a planar view; a plurality of light emitting elements 120 provided in the outer peripheral region 140; a plurality of circuit components 161 being provided in the inner peripheral region 150, and for causing the plurality of light emitting elements 120 to emit light; and a metallic circuit cover 30 covering the inner peripheral region 150. The inner peripheral region 150 includes a high-voltage region 151, a low-voltage region 152, and a boundary region 153 located between the high-voltage region 151 and the low-voltage region 152. A through hole 118 penetrating the board 110 is provided in the boundary region 153.SELECTED DRAWING: Figure 6 【課題】十分な延焼距離及び絶縁距離を確保する。【解決手段】照明器具１は、器具本体１０と、器具本体１０に載置され、平面視において互いに異なる外周領域１４０及び内周領域１５０を有する基板１１０と、外周領域１４０に設けられた複数の発光素子１２０と、内周領域１５０に設けられ、複数の発光素子１２０を発光させるための複数の回路部品１６１と、内周領域１５０を覆う金属製の回路カバー３０とを備える。内周領域１５０は、高電圧領域１５１と、低電圧領域１５２と、高電圧領域１５１と低電圧領域１５２との間に位置する境界領域１５３とを含む。境界領域１５３には、基板１１０を貫通する貫通孔１１８が設けられている。【選択図】図６
