LIGHTING DEVICE AND ILLUMINATING APPARATUS

PROBLEM TO BE SOLVED: To provide a lighting device and an illuminating apparatus that are downsized.SOLUTION: A lighting device 1 includes a circuit board 150 whose planar shape is rectangular. The circuit board 150 has at least a plurality of light source modules 21, 22, and 23, a plurality of power storage elements 41, 42, and 43, and a light detection sensor 50 mounted on the same mount plane 154. LEDs 211, 221, and 231 of the plurality of light source modules 21, 22, and 23 are disposed on the circuit board 150 along one side of the circuit board 150. In the circuit board 150, the plurality of power storage elements 41, 42, and 43 is disposed between the mount positions of the LEDs 211, 221, and 231 and the mount position of the light detection sensor 50.SELECTED DRAWING: Figure 3 【課題】小型化が図られた点灯装置及び照明器具を提供する。【解決手段】点灯装置１は、平面形状が長方形の回路基板１５０を備える。回路基板１５０には、同一の実装面１５４に、複数の光源モジュール２１，２２，２３と、複数の蓄電素子４１，４２，４３と、光検出センサ５０とが少なくとも実装される。複数の光源モジュール２１，２２，２３の各々が有するＬＥＤ２１１，２２１，２３１は、回路基板１５０の一辺に沿って並ぶように回路基板１５０に配置される。回路基板１５０においてＬＥＤ２１１，２２１，２３１の実装位置と光検出センサ５０の実装位置との間には複数の蓄電素子４１，４２，４３が配置されている。【選択図】図３
