Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a light source module inhibiting a temperature of a solid light source from excessively rising: and to provide a lighting fixture.SOLUTION: At least two solid light sources 9 of a plurality of solid light sources 9 belong to each of a plurality of light source systems. At least two solid light sources 9 are electrically connected in series, in parallel or in series-parallel. At least two solid light sources 9 are subjected to constant current control. In a first light source system out of the plurality of light source systems, an electrical parallel number of at least two solid light sources 9 is smaller than that of a second light source system out of the plurality of light source systems. The first light source system is arranged so as to be nearer to the center of an area 34 provided with the plurality of solid light sources 9 in one direction (first direction D1), than the second light source system.SELECTED DRAWING: Figure 1
【課題】固体光源が過度に温度上昇することを抑制することができる光源モジュール及び照明器具を提供する。【解決手段】複数の光源系の各々には、複数の固体光源9のうち2以上の固体光源9が属する。2以上の固体光源9は、電気的に直列、並列又は直並列に接続されている。2以上の固体光源9は、定電流制御される。複数の光源系のうちの第一光源系は、複数の光源系のうちの第二光源系よりも、2以上の固体光源9の電気的な並列数が小さい。第一光源系は、第二光源系よりも、一の方向(第一方向D1)において、複数の固体光源9が設けられている領域34の中心により近く配置されている。【選択図】図1 |
