The lighting fixture 10 is, for example, a direct-installation-type lighting fixture 10 attached to a ceiling surface, and a main body chassis 12 and a reflector 13 attached to the main body chassis 12. , The end plate 14 and the lighting device 15, two lamp sockets 16 attached to the reflector 13, a fluorescent lamp 18 attached to the lamp socket 16, and the like. Hereinafter, directions such as up and down and both sides will be described with reference to a state in which the lighting fixture 10 is attached to the ceiling surface.

  The main body chassis 12 is integrally formed in a substantially U-shaped cross-section by extrusion molding of aluminum, and extends downward from both side portions along the longitudinal direction of the substrate portion 21. Side plate portions 22 and main body side flange portions 23 projecting in a plate shape by a predetermined dimension in the direction of approaching each other, from the front end portions, that is, lower end portions of these side plate portions 22, except for parts that are processed separately The same cross-sectional shape is formed over the entire length. Further, reinforcing rib portions 25 projecting thickly outward are formed along the upper and lower end portions of the side plate portion 22 in the vicinity of the four corners of the main body chassis 12, and these rib portions 25 are formed. At the end in the longitudinal direction, a mounting portion 28 to which a mounting tool 27 such as a screw is fixed is formed in a dovetail shape by extrusion molding or by a separate process from extrusion molding. Further, the tip of each rib portion 25 is formed in a semicircular shape. Furthermore, although not shown in the figure, the board portion 21 of the main body chassis 12 is formed with a mounting hole into which a mounting bolt is inserted, a wire introduction port into which a power line is inserted, and the like by a process different from extrusion molding. .

  In addition, a portion surrounded by the substrate portion 21 and the side plate portion 22 of the main body chassis 12 becomes a space portion 30 which is a component storage space. In the space portion 30, a lighting device 15 such as a ballast or a terminal block (not shown) Etc. are arranged and fixed to the board portion 21 by screws or the like.

  In addition, the reflector 13 is integrally formed by extrusion molding of aluminum, and has a reflector base portion 31 having an elongated rectangular shape, and a reflection extending in a curved downward direction from both side portions along the longitudinal direction of the reflector base portion 31. The cap portion 32 is provided, and is formed in the same cross-sectional shape over the entire length except for another processed portion. Further, reflector-side flange portions 33 are formed on both side portions of the reflector base portion 31 along the longitudinal direction. These reflector-side flange portions 33 include a short vertical wall portion 34 that faces upward, and a horizontal wall portion 35 that faces outward from the upper end portion of the vertical wall portion 34, together with a part of the reflector base portion 31, outward. It is configured as an engaging portion having an approximately U-shaped cross section. Furthermore, an edge portion 37 is provided at the front end portion of each reflective shade portion 32 so as to extend upward and outward. In addition, in the vicinity of both end portions of the reflector base 31, socket mounting portions 38 are formed by processing different from extrusion molding.

  Further, the end plate 14 is a flat plate made of metal such as a flat square metal, and mounting holes 41 into which the fixtures 27 are inserted are formed in the vicinity of the four corners. It is formed in a curved shape according to the shape.

  The two lamp sockets 16 are attached to the socket attaching portions 38 in a state of facing each other, and are connected to the lighting device 15 and the like by wires 43, respectively.

  Further, the fluorescent lamp 18 is a straight tube type fluorescent lamp 18 provided with caps at both ends, and is mounted between the lamp sockets 16 so that the longitudinal direction of the main body chassis 12 and the reflector 13, that is, the longitudinal direction of the lighting fixture 10. It will be in the state arrange | positioned facing the reflector base 31 and the reflective shade part 32 along a direction.

  Next, an assembly process of the lighting fixture 10 will be described.

  First, from one end in the longitudinal direction of the main body chassis 12 assembled with the lighting device 15 in advance, the reflector side flange portion 33 of the reflector 13 is fitted to the main body side flange portion 23, and the reflector 13 is inserted while sliding, The main body side flange portion 23 and the reflector side flange portion 33 are engaged with each other over the entire length, and the reflector 13 is attached to the main body chassis 12.

  Further, before or after the reflector 13 is attached to the main body chassis 12, the lamp socket 16 is attached to each socket attaching portion 38 of the reflector 13, and each lamp socket 16 is connected to the lighting device 15 or the like by the wiring 43.

  Then, both end portions of the main body chassis 12 are fitted by fitting the end plates 14 to the both end portions of the main body chassis 12 and tightening the fittings 27 inserted into the mounting holes 41 to the mounting portions 28 by screwing or self-tapping. The end plate 14 is screwed to the end.

  In this state, the lower side of the space 30 of the main chassis 12 is closed by the reflector base 31 of the reflector 13, both ends are closed by the end plate 14, and the space 30 is sealed, for example, approximately liquid-tightly. At the same time, the movement of the reflector 13 is prevented by the end plate 14 and is securely fixed, and the lighting fixture 10 is configured.

  Thus, according to the present embodiment, the main body chassis 12 and the reflector 13 are formed by extrusion molding of aluminum, and at least the main body side flange portion 23 and the reflector side flange portion 33 are formed on the main body chassis 12 and the reflector 13. Since the same cross-sectional shape is formed over the entire length, the reflector 13 can be easily and firmly attached to the main body chassis 12 by sliding and engaging the flange portions 23 and 33 with each other.

  Then, by attaching the end plates 14 to both ends of the main body chassis 12, the space 30 can be closed and the reflector 13 can be prevented from coming off and fixed securely, thereby simplifying the structure and reducing the manufacturing cost.

  Furthermore, because the body chassis 12 and the reflector 13 are formed by extrusion molding of aluminum, for example, the installation space of the molding apparatus can be reduced and the change in shape can also be compared as compared with roll former molding that processes thin sheet metal. The manufacturing cost can be reduced.

  For example, in the above embodiment, the reflector 13 is a so-called reflector with a shade that extends the reflector shade 32 from both sides of the reflector base 31, but is not limited to this configuration. For example, FIG. As shown in FIG. 5, it is possible to provide a reflector with one side of the reflector base 31 extending from one side of the reflector base 31. Further, as shown in FIG. It is possible to improve the versatility by using a shadeless reflector without the shade portion 32 and using it in combination with the common main body chassis 12. In addition, the reflection plate with a cap or the reflection plate without a cap can be formed by changing a mold of extrusion molding, or can be formed by cutting a part of the reflection plate with a cap.

  Moreover, since the main body chassis 12 and the reflector 13 are formed by extrusion molding of aluminum, the elongated member is cut into an arbitrary length dimension to form the main body chassis 12 and the reflector 13 having an arbitrary longitudinal dimension. You can also. Therefore, for example, it is possible to easily cope with a change in the longitudinal dimension such as downsizing of the lighting fixture 10 corresponding to the downsizing of the ballast or the lamp, or so-called line illumination for two or three lamps having a large longitudinal dimension. Therefore, compared to a configuration using roll former molding, it is possible to easily cope with so-called model change of the lighting fixture 10 while reducing manufacturing costs such as capital investment.

  For example, as shown in FIG. 6, a main body chassis 12 and a reflector 13 having large longitudinal dimensions are formed, and other end plates 14 and the like are made of a linear light source using a common member with the lighting fixture 10 for one lamp. Line lighting for three lamps in which three straight fluorescent lamps 18 are arranged in a straight line can be easily realized. In the line lighting for three lamps, the main body chassis 12 and the reflector 13 of the lighting fixture 10 are seamless, and the appearance and the sealing performance can be easily improved.

  In each of the above embodiments, the straight tube fluorescent lamp 18 having the bases at both ends is used as the light source. However, the present invention is not limited to this configuration. For example, the single-sided lamp having the base at one end in the longitudinal direction is used. An appropriate linear light source such as a mold fluorescent lamp can be used.

  The present invention relates to a lighting fixture that lights, for example, a straight tube fluorescent lamp.
