ILLUMINATING SYSTEM

To provide an illuminating system having a constitution in which a substrate cover can be temporarily placed on a housing stably, and the occurrence of improper attachment of the substrate cover to the housing can be suppressed even when the illuminating system is automatically assembled using a robot.SOLUTION: An illuminating system 1 is provided, comprising: a substrate cover 10 which has a bottom wall 11, and a first side wall 12 continuous with the bottom wall 11 and having a fitting hole 13; a housing 20 having a second side wall 21 having a claw 22 which protrudes outward and fits into the fitting hole 13; a substrate 30 which is sandwiched between the bottom wall 11 of the substrate cover 10 and the housing 20 and is fixed by fitting the claw 22 into the fitting hole 13, wherein a light-emitting element 32 and a switch 33 switching operation of the light-emitting element 32 are mounted on a wiring plate 31; and a lens 50 mounted on the housing 20 and acting as a light-emitting surface, wherein the claw 22 is arranged away from a tip 21b of the second side wall 21.SELECTED DRAWING: Figure 3 【課題】基板カバーをハウジング上に安定して仮置きすることができ、ロボットによる自動組立を行う場合であっても、基板カバーのハウジングへの取り付け不良の発生が抑えられる構造を有する照明装置を提供する。【解決手段】底壁１１、及び底壁１１に連続した、嵌合孔１３を有する第１の側壁１２を有する、基板カバー１０と、嵌合孔１３に嵌合する外側に突出した爪２２を有する第２の側壁２１を有するハウジング２０と、爪２２を嵌合孔１３に嵌合させることにより、基板カバー１０の底壁１１とハウジング２０とに挟まれて固定される、発光素子３２及び発光素子３２の動作を切り替えるスイッチ３３が配線板３１に実装された基板３０と、ハウジング２０に取り付けられた、発光面となるレンズ５０と、を備え、爪２２が、第２の側壁２１の先端２１ｂから離れて設けられた、照明装置１を提供する。【選択図】図３
