To provide duct structure which includes air duct, a light source disposed in the air duct, and a substrate and enables increase of flexibility of the irradiation direction of a light source disposed in the air duct, and enables a wire to be easily wired while increasing the cooling effect of the substrate.SOLUTION: Duct structure comprises: a duct body 40 as a main body forming an air flow passage; a first light source 60 and a second light source 62 disposed inside the duct body 40; and a substrate 64 on which the duct body and the first and second light sources are mounted. The substrate 64 has a plurality of substrate portions 65, 66, 67 each of which is extended in a direction intersecting with the duct body 40 and the adjacent plate surfaces of which are intersected with one another. The substrate portions include the first substrate portion 66 on which at least the first light source 60 is mounted, and the second substrate 67 on which the second light source 62 is mounted. A traverse passage 70 traversing the air flow passage on the inside surrounded by the plurality of substrate portions 65, 66, 67, and two substrates 65, 66 intersect with each other on the upstream side of the air passage with their distal end thin on the upstream side of the air flow passage.SELECTED DRAWING: Figure 5
【課題】エアダクト内に配置する光源の照射方向の自由度を高めるとともに、基板の冷却効果を高めつつ、配線を容易に配策可能なダクト構造を提供する。【解決手段】空気流路を形成する主体となるダクト本体40と、ダクト本体40の内部に配される第1光源60および第2光源62と、それらが実装される基板64と、を備え、その基板64が、それぞれがダクト本体40に対して空気流路と交差する方向に延設され、隣り合うものの板面が互いに交差する複数の基板部65,66,67を有し、その基板部が、少なくとも第1光源60が実装された第1基板部66と第2光源62が実装された第2基板部67とを含み、複数の基板部65,66,67で囲まれた内側に、空気流路を横断する横断路70を形成するとともに、2つの基板部65,66が、空気流路の上流側に先細りとなるよう交差する構造とする。【選択図】図5
