A heat sink having heat dissipation fins; and a main body frame fixed to the heat sink . The heat dissipation plate has a first edge portion to which the main body frame is fixed, and the main body frame to be fixed. The main frame has a plate-shaped top surface portion that is provided on the second surface of the heat dissipation plate with a gap, and a second edge portion that is opposite to the edge portion of the top surface portion and one end portion of the top surface portion. 1 has a plate-shaped first side surface portion extending to the edge portion of 1 and a plate-shaped second side surface portion extending from the other end portion of the top surface portion to the second edge portion, and the first side surface portion is , Radiating heat to the end on the side of the heat dissipation plate that extends in parallel to the first edge and is in contact with the first edge, and to the end in the direction parallel to the first surface. A bent portion provided so as to protrude toward the fin side, an end portion in a direction parallel to the first surface, and a protruding portion provided at the bent portion so as to protrude below the first fixed end portion, the second side surface portion, extends parallel to the second edge at the end portion of the radiator plate side, and a second fixed end is in contact with the second edge, parallel to the first surface A bent portion projecting toward the radiation fin side at the end in the direction, and a projecting portion projecting below the first fixed end at the end in the direction parallel to the first surface and the bent portion. And the projecting portions of the first side surface portion and the second side surface portion are located along the four corners of the heat dissipation plate.
本発明によれば、樹脂部品を第１の側面部と第２の側面部との間であって天面部と放熱板との間に配置することにより、照明器具は、樹脂部品が環境要因によって劣化してしまうことを抑制できる構造である。また、本体フレームの突出部が放熱板の４つの角部に沿って位置する構成により、放熱板の本体フレームとの相対移動が制限され、照明器具は、強度及び剛性を確保しつつ軽量化が図れるため取付性も向上する。 According to the present invention, by disposing the resin component between the first side surface portion and the second side surface portion and between the top surface portion and the heat dissipation plate, the luminaire has it is a structure that can be curbing that deteriorated. In addition, since the projecting portions of the main body frame are located along the four corners of the heat dissipation plate , the relative movement of the heat dissipation plate with respect to the main body frame is limited, and the lighting fixture can be made lightweight while ensuring strength and rigidity. Since it can be achieved, the mountability is improved.
