JP 2002-109944 A (paragraphs 0022-0024, 0036-0041, FIG. 1, FIG. 2, FIG. 10, FIG. 11)

  In the conventional technology in which the glove is an integrally molded product of synthetic resin, it is difficult in terms of molding technology to reduce the thickness of each part of the glove to a certain extent, so the glove has to be relatively heavy. Lightening the glove that covers the lamp not only reduces the weight of the fixture, but is also a lighting fixture installed on the ceiling of a vehicle lighting fixture or the like. This is preferable in that the workability when opening and closing can be improved. However, such a request for weight reduction cannot be satisfied by the technique of Patent Document 1.

  An object of the present invention is to provide a lighting fixture that can reduce the weight of a light control body that covers a lamp, and can support the light control body in a predetermined shape regardless of the weight reduction.

  The invention according to claim 1 is an instrument main body which is rectangular in plan view and opened downward; a lamp supported by the instrument main body; a pair of frame members extending in the longitudinal direction of the instrument main body and ends of the frame members A light control body holder that is formed in a rectangular frame shape with an end frame member disposed between, and is attached to the instrument body so as to be openable and closable and is disposed around the lower outer periphery of the instrument body, A light control body holder in which the frame member has an inward projecting portion projecting toward the lamp side and a support edge projecting toward the lamp side located near the lower side of the inward projecting portion; A light control body having an overhanging edge that is open upward and is bent outward, and a light control that is adhered to the light control body and is disposed with the longitudinal end of the light control body closed. A body end plate, and the light-extinguishing edge is hooked on the supporting edge A light control body supported by a holder and covering the lamp from below; and a presser edge that clamps the overhang edge between the support edge over substantially the entire length in the longitudinal direction thereof, and a pair of the frame members, respectively. And a fixed light-controlling body presser.

  According to the first aspect of the present invention, the light control body has a predetermined shape by adhering a light control body end plate that closes the longitudinal end of the light control body to the longitudinal end of the light control body. Assembled. Therefore, there is no thickness restriction as in the case where the light control material forming the light control body and the light control body end plate is integrally formed, and a thin material such as thin paper can be used for the light control material. Therefore, it can be set as the lighting fixture using a lightweight light control body.

  By the way, the light control body which became light weight by thinning is easy to deform | transform the upper end part of the light control body main body extended in the longitudinal direction. Along with this, when a plurality of light control body pressers that sandwich the extension edge of the light control body main body with the support edge of the frame body are used as in the prior art, these are arranged at intervals in the longitudinal direction of the extension edge. A portion that is not pressed by the light control body presser may be easily deformed, and the upper end portion of the light control body may be deformed so as to wave.

  As a countermeasure against this, the invention according to claim 1 uses a light control body presser having a presser edge that holds the overhanging edge of the light control body main body between the support edge of the frame member over the entire length in the longitudinal direction. The upper end portion of the light control body is prevented from being deformed so as to wave, and the light control body can be held in a predetermined shape and supported by the light control body holder. In addition, since the overhang edge is sandwiched from above and below over the entire length in the longitudinal direction, the longitudinal intermediate portion of the overhang edge is disengaged from the support edge even when the longitudinal intermediate portion of the light control body is pushed from the side. This can be suppressed.

  According to a second aspect of the present invention, in the first aspect of the invention, the end frame member of the light control body holder is provided continuously on the lower surface of the inward projecting portion, and the light control body is An end member bonded along the inner surface of both longitudinal ends of the light control body is provided, and the end member is formed to have a portion provided straight across both ends in the width direction of the light control body. And this portion is arranged in the vicinity of the lower side of the end frame member so as to be flush with the upper surfaces of the pair of overhang edges, and the end frame member, the portion, and the overhang edge continuous therewith. It is characterized by sandwiching insect-proof packing between them.

  In the invention of claim 2, since the insect-proof packing is elastically deformed and sandwiched between the longitudinal end of the light control holder and the longitudinal end of the light control body, an insect-proof lighting device can be obtained. . In addition, the force that the elastically deformed insect-proof packing tries to return can be received by the second portion of the end member so that the force does not act on the thin light-control body end plate. Thereby, the side which contacted the waterproof packing of the light control body end plate is prevented from being deformed so as to wave, and the light control body can be held in a predetermined shape.

  According to the lighting apparatus of the first aspect of the present invention, since the light control body that is formed without integral molding and covers the lamp is used, the light control body can be reduced in weight, and regardless of the weight reduction. The overhanging edge side of the light control body provided in the light control body can be prevented from wavy and the light control body can be held in a predetermined shape.

  According to the lighting fixture of the invention according to claim 2, in addition to being able to be an insect-proof lighting fixture, it is possible to prevent the insect-proof packing side of the light control body end plate provided in the light control body from undulating due to the insect-proof packing. The light control body can be held in a predetermined shape.

  A lighting apparatus according to an embodiment of the present invention used as a train interior light will be described with reference to FIGS.

  As shown in FIG. 1 and FIG. 2, the lighting fixture 1 includes a fixture body 2, a lighting device 5, a lamp socket 6, a lamp such as a straight tube type fluorescent lamp 7, and a light control holder such as a glove holder ( (Hereinafter abbreviated as a holder) 11, a glove 21 as a light control body, and a glove presser 31 and the like as a light control body press. In the present invention, the lamp, that is, the light source is not limited to a fluorescent lamp, and a lamp using a semiconductor light emitting element such as a light emitting diode as a light source, or a lamp using an organic EL (electroluminescence) element as a light source is also used. can do.

  The instrument body 2 has a rectangular shape in plan view and is open downward. The instrument main body 2 is formed of a main body main portion 3 and a pair of main body end plates 4 (only one is shown in FIGS. 1 and 2). The main body end plate 4 is attached to both ends in the longitudinal direction of the main body main portion 3 with the opening of the end closed.

  The main body 3 includes a horizontal central wall portion 3a, a pair of slanted wall portions 3b, a horizontal pair of overhanging wall portions 3c, and a pair of side wall portions 3d. The pair of oblique wall portions 3b are bent obliquely downward from both sides of the central wall portion 3a, and are inclined in opposite directions to be provided in a C shape. The pair of overhanging wall portions 3c are bent outward from the lower edge of the inclined wall portion 3b in opposite directions. The pair of side wall portions 3d are bent vertically downward from the overhanging wall portion.

  The appliance main body 2 has a pair of overhanging wall portions 3c abutting against a ceiling surface (not shown) of a train, and a pair of slanted wall portions 3b and a central wall portion 3a are embedded in the ceiling holes. Inserted into the ceiling surface. This installation is performed by screwing a screw passing upward through the overhanging wall portion 3c into the ceiling surface.

  The main body main part 3 and the main body end plate 4 are both made of a steel plate, for example, a white pre-coated steel plate. The coated surface of the steel sheet is composed of a paint layer containing a white pigment and a resin layer as a protective layer covering this layer. This coated surface is disposed facing the inner space of the instrument body 2 so that the entire inner surface of the instrument body 2 functions as a reflective surface.

  The reflectance at the coating layer increases as the film thickness increases, but the bending workability of the main body 3 decreases as the film thickness increases. Therefore, the maximum thickness is preferably set within a range not impairing the workability. Furthermore, the reflectance of the resin layer depends on the size and content of titanium oxide particles that are resin pigments contained therein. For this reason, it is preferable to increase the reflectance of the resin layer by increasing the selection and content of titanium oxide particles. In this embodiment, by taking these measures and using a high-reflectance white pre-coated steel sheet in which the reflectance of the instrument body 2 is improved to 92% compared to the conventional 83%, the instrument luminous flux is improved by 12%. However, since the power consumption of the appliance was reduced by 12%, the inherent energy consumption efficiency of the appliance was improved by 27%.

  The lighting device 5 is composed of, for example, a discharge lamp ballast. The lighting device 5 is screwed to the upper surface of the central portion in the longitudinal direction of the central wall 3a. Lamp sockets 6 (only one is shown in FIG. 2) are attached to the lower surfaces of both ends in the longitudinal direction of the central wall 3a. A fluorescent lamp 7 is detachably supported between the pair of lamp sockets 6. The fluorescent lamp 7 may be a lamp that emits white light. For example, a lamp that emits white light by mixing three wavelengths can be suitably used.

  As shown in FIG. 1, the holder 11 connects a pair of frame members 12 and a pair of end frame members 16, and is formed in a long rectangular frame shape that is slightly larger than the instrument body 2, as shown in FIG. 2. Is disposed so as to surround the outer periphery of the lower part of the instrument body 2. The pair of frame members 12 are made of an extruded product of an aluminum alloy, are arranged in parallel to each other, and extend in the longitudinal direction of the instrument body 2. The pair of end frame members 16 are made of a steel plate and have a pair of bent connection pieces (only one is shown in FIG. 5) 16a. By screwing these connecting pieces 16 a to the longitudinal ends of the frame member 12, the end frame member 16 is attached across the longitudinal ends of the pair of frame members 12.

  As representatively shown in FIG. 3, each frame member 12 has a support edge 13 that protrudes inwardly at the lower end, that is, bent toward the fluorescent lamp 7 side. Further, each frame member 12 has an inward protruding portion 14 that protrudes inward from the inner surface thereof, that is, integrally with the fluorescent lamp 7 side. The support edge 13 is shorter than the inward projecting portion 14 and is provided near the lower side of the inward projecting portion 14, and a gap is formed between the support edge 13 and the inward projecting portion 14.

  The inward projecting portion 14 includes a root portion 14a that is opposed to the support edge 13 that is horizontally projected from the inner surface of the frame member 12, a rising portion 14b that is bent upward from the root portion 14a, and an inner surface of the frame member 12. The packing receiving portion 14c is bent from the upper end of the rising portion 14b in a direction away from the rising portion 14b. As shown in FIGS. 3 and 5, an insecticidal packing 20 a that can be elastically deformed is bonded to the upper surface of the packing receiving portion 14 c.

  The pair of end frame members 16 are made of a steel plate and have a pair of bent connection pieces (only one is shown in FIG. 5) 16a. By screwing these connecting pieces 16 a to the rising portion 14 b at the longitudinal end of the frame member 12, the end frame member 16 is attached between the longitudinal ends of the pair of frame members 12. By this attachment, the end frame member 16 is provided so as to be flush with the lower surface of the root portion 14 a of the inward projecting portion 14, and the both ends in the longitudinal direction of the end frame member 16 are in contact with the inner surface of the frame member 12. It has been.

  As shown in FIGS. 4 and 5, the end frame member 16 has a packing receiving portion 16b that is continuous to the packing receiving portion 14c at a right angle, and an insecticidal packing 20b that can be elastically deformed is bonded to the upper surface thereof. . The insect-proof packings 20a and 20b are continuous at a right angle.

  One frame member 12 of the holder 11 having the above configuration is rotatably connected to one side wall portion 3d of the instrument body 2 by hinges (only one is shown in FIG. 2) 18 at a plurality of positions in the longitudinal direction. Latch fittings 19 (only one is shown in FIG. 2) 19 are attached to a plurality of positions in the longitudinal direction of the other frame member 12 of the holder 11.

  The holder 11 is opened and closed with respect to the instrument body 2 by rotating around the hinge 18 as a fulcrum. This opening and closing is performed at the time of lamp replacement or the like. The latch fitting 19 can be engaged with and disengaged from the latch engaging portion 3e provided on the other side wall portion 3d, and the latch fitting 19 is hooked on the latch engaging portion 3e as shown in FIG. The holder 11 is held in the closed position (this holding state is shown in FIG. 2). In the state where the holder 11 is disposed at the closed position, the insect-proof packings 20a and 20b are brought into close contact with the lower surface of the overhanging wall portion 3c of the fixture body 2 with elastic deformation as shown in FIG. Insect protection is being planned. The pushing portion 19a (see FIG. 3) included in the latch metal fitting 19 is manually pushed from the outside of the holder 11 when removed from the latch engaging portion 3e.

  As shown in FIG. 6 and FIG. 7 (where the cross-sectional portion in FIG. 7 is drawn with a thick line instead of hatching), the translucent globe 21 as the light control body is a single light control body. A main body such as a globe body 22, a pair of end members 23 (only one shown), and a pair of light control end plates such as a globe end plate 24 (only one shown) are formed.

  The globe 21 is substantially the same length as the frame member 12, is open upward, and has a protruding edge 22 a that is bent outward from its upper end to form a groove shape. The groove shape of the globe 21, that is, the cross-sectional shape in the direction orthogonal to the longitudinal direction of the globe 21 is substantially trapezoidal in the illustrated example, but this groove shape can be arbitrarily designed, for example, substantially arc-shaped It doesn't matter.

  The end member 23 has a strength that does not easily deform, and is made of the same color as the globe body 22 and the globe end plate 24, for example, a white synthetic resin material. The end member 23 is formed in a ring shape from the first portion 23a and the second portion 23b.

  The first portion 23 a has a shape along a cross-sectional shape in a direction orthogonal to the longitudinal direction of the globe 21. The second part 23b is provided straight across both ends of the first part 23a. These end members 23 are respectively disposed on the inner surfaces of both ends of the globe 21 in the longitudinal direction using an adhesive. In FIG. 6, reference numeral S <b> 1 indicates a bonding region planned on the inner surface of the end of the globe 21. The flat upper surface of the second portion 23b of the bonded end member 23 is flush with the pair of overhanging edges 22a.

  The pair of globe end plates 24 are respectively bonded to the end members 23 to close the longitudinal ends of the globe body 22. In FIG. 6, reference numeral S <b> 2 indicates an adhesion region planned on the inner surface of the peripheral portion of the globe end plate 24. The globe end plate 24 has an end plate protruding edge 24a bent from the upper end thereof. The end plate overhanging edge 24a is continuously flush with the upper surface of the second portion 23b and protrudes in a direction away from the second portion 23b.

  The globe body 22 and the globe end plate 24 are made of the same kind of light control material having translucency. The globe body 22 is preferably made of the following light control material, but the globe end plate 24 may be formed of a different light control material.

  As the light control material for forming the globe body 22 and the like, a thin material formed by laminating a heat resistant layer 26 on the surface of the incombustible layer 25 and laminating an adhesive layer 27 on the back surface of the incombustible layer 25 as shown in FIG. Can be used. The film thickness of this light control material is, for example, 0.5 ± 0.1 mm. Therefore, the glove 21 formed with the glove body 22 and the glove end plate 24 occupying most of the parts is much lighter than the glove of the resin molded product.

  The incombustible layer 25 is made by stacking incombustible materials in multiple layers. As a layer which consists of nonflammable materials, the layer which uses glass fiber as a main material (base material) can be mentioned, for example. The glass fiber layer has a very high melting point, and the non-combustible layer 25 formed by laminating this layer can impart non-combustibility to the light control material having this as a core. For this reason, even if a flame acts, the glove body 22 and the glove end plate 24 do not rarely burn like a flame-retardant synthetic resin such as an acrylic resin or a polycarbonate resin.

  The heat-resistant layer 26 is made of a heat-resistant single layer or a plurality of layers. An example of the heat resistant material is ethylene tetrafluoride. Since the tetrafluoroethylene layer has high heat resistance, it does not melt with high heat when a flame acts on the light control material from the surface side. Further, since the structure of the heat-resistant layer 26 of ethylene tetrafluoride is extremely dense, the surface roughness is extremely small, and it is difficult for dust to adhere to the surface of the heat-resistant layer, and the attached dust can be easily removed.

  The adhesive layer 27 is made of a single layer or a plurality of layers for adhering the glove body 22 and the glove end plate 24 to the end member 23 using an adhesive, and examples of the adhesive material include flame retardant polycarbonate resin. Can be mentioned. The adhesive layer 27 has a melting point lower than that of the material for forming the heat-resistant layer 26, and has much better adhesion performance than the heat-resistant layer 26.

  The globe 21 has a pair of overhanging edges 22 a inserted from one end in the longitudinal direction of the frame member 12 into a gap formed between the support edge 13 and the inward projecting portion 14 and extending in the longitudinal direction of the main body 3. The main body 3 is supported by being hooked on the support edge 13 of the frame member 12. In this case, the second portion 23b of the end member 23 is disposed to face the lower vicinity of the end frame member 16 of the main body 3 in a state where the globe 21 is disposed at an appropriate position. Yes.

  An insect-proof packing 29 made of a material that can be elastically deformed is sandwiched between the overhanging edge 22a and the second portion 23b that are continuous with each other and the end frame member 16. The insect-proof packing 29 is also in contact with the end plate overhanging edge 24a. The insect-proof packing 29 is sandwiched as described above with elastic deformation by being pushed toward the longitudinal center of the main body 3 along the longitudinal direction of the main body 3. I'm trying to prevent insects.

  As shown in FIG. 4 and the like, the globe presser 31 is made of an elongated metal plate having substantially the same length as the frame member 12, and includes a base portion 31a, a positioning edge 31b, a presser edge 31c, and a plurality of plate nuts 32. ing.

  The base portion 31 a is a portion that overlaps the lower surface of the root portion 14 a of the frame member 12. The positioning edge 31b is formed by being bent vertically upward from one end in the width direction of the base portion 31a and overlapping the inner surface of the rising portion 14b of the frame member 12. The presser edge 31 c is formed by bending obliquely from the other end in the width direction of the base portion 31 a, and is a part that sandwiches the overhang edge 22 a between the support edge 13. The plate nut 32 is welded at predetermined intervals along the longitudinal direction of the base portion 31a. The base portion 31a has a through hole (not shown) that communicates with the screw hole 32a of the plate nut 32. The same highly reflective coating as that applied to the inner surface of the instrument body 2 is applied to the surface of the globe presser 31, that is, the surface that does not face the inward protruding portion 14.

  The glove retainer 31 has a screw 33 attached to the frame member 12 before the holder 11 is attached to the instrument body 2 and in a state where the globe 21 and the insect-proof packing 29 are attached to the holder 11 according to the procedure described above. Fixed using. This fixing procedure is as follows.

  First, while the presser edge 31c is inserted into the gap between the support edge 13 and the root part 14a with its elastic deformation, the angle formed by the base part 31a and the positioning edge 31b is set to the root part 14a of the inward projecting part 14. And the angle formed by the rising portion 14b. Accordingly, the globe presser 31 is disposed along substantially the entire length in the longitudinal direction of the frame member 12, and the presser edge 31 c elastically holds the protruding edge 22 a between the support edge 13. This clamping is performed for substantially the entire length in the longitudinal direction of the overhanging edge 22a because the globe presser 31 has substantially the same length as the frame member 12.

  Next, after finely adjusting the position in the longitudinal direction of the glove presser 31, the screw 33 from above is inserted into the screw hole 32a of the plate nut 32 and the screw through hole 34 (see FIGS. 3 and 4) formed in the root portion 14a. The screw 33 is screwed into the plate nut 32 and tightened. As a result, the globe presser 31 is fixed to the frame member 12, and the protruding edge 22a of the globe 21 is sandwiched between the presser edge 31c and the support edge 13 over substantially the entire length.

  The globe 21 provided in the insect-proof illuminating device 1 having the above-described configuration is configured such that the inner surface of the end of the globe body 22 in the longitudinal direction is bonded to the end members 23 arranged at both ends in the longitudinal direction, and the length of the globe body 22 is long. A glove end plate 24 that closes the end in the direction is bonded to obtain a predetermined shape defined by the shape of the end member 23 and assembled.

  For this reason, unlike the case where the globe 21 is integrally molded with a synthetic resin, there is no restriction on the thickness when integrally forming the light-damping material forming the globe body 22 and the globe end plate 24. Thin-walled material such as thin paper can be used. Therefore, the globe 21 is reduced in weight, and the luminaire 1 can be reduced in weight accordingly.

  As described above, the glove 21, which has been thinned for weight reduction, easily deforms the upper end portion of the glove body 22 extending in the longitudinal direction.

  However, a glove presser 31 having substantially the same length as that of the frame member 12 is used, and the overhang edge 22a of the glove body 22 is sandwiched between the presser edge 31c and the support edge 13 of the frame member 12 over the entire length in the longitudinal direction. ing. For this reason, it is prevented that the upper end part of the glove body 22 supported by the holder 11 is deformed so as to wave. Moreover, in this insect-proof type lighting fixture 1, the force that the elastically-transformed insect-proof packing 29 tries to return to the free state is received by the second portion 23b of the end member 23. Accordingly, the force can be prevented from acting on the upper edge portion of the thin glove end plate 24 as in the case of the glove body 22, so that the upper edge portion of the glove end plate 24 can be prevented from being deformed so as to wave.

  Therefore, since the globe 21 can be held in a predetermined shape, it is possible to prevent the appearance of the lighting fixture 1 from deteriorating as the globe 21 is reduced in weight. Further, since the glove 21 has been reduced in weight, it is possible to improve workability when the glove 21 is opened and closed during cleaning work or lamp replacement.

  Further, as described above, the overhang edge 22a is sandwiched from above and below over the entire length in the longitudinal direction, so that even when the intermediate portion in the longitudinal direction of the glove body 22 is pushed from the side, the intermediate portion in the longitudinal direction of the overhang edge 22a. It is possible to prevent the glove 21 from being easily removed from the holder 11 by preventing the portion from being detached from the support edge 13.

  In addition, the globe 21 includes the non-combustible layer 25 made of glass fiber as described above, and has a structure in which the heat-resistant layer 26 is laminated on the surface thereof. Has been. For this reason, unlike a flame-retardant glove, when a flame is applied from outside the appliance body 2 to hold a fire in a vehicle, the glove 21 does not burn, and even if the glove 21 is thin, excellent fire resistance Can be demonstrated.

  In the lighting state of the lighting fixture 1, the light emitted from the fluorescent lamp 7 is irradiated through the globe body 22 and the globe end plate 24 of the globe 21. By the way, as described above, the non-flammable globe 21 has a light transmittance lower than that of a globe integrally formed of a flame-retardant synthetic resin such as polycarbonate resin because of its material. However, in response to this, since the high reflection performance is imparted by the paint layer applied to the inner surface of the instrument body 2 as described above, the brightness of the irradiation field can be improved.

  Further, as a result of trial production by the present inventor, when a fluorescent lamp having a white emission color is used and this lamp is viewed through the non-combustible globe 21 having the multilayer structure, the lamp image displayed on the globe body 22 is yellowish. It became clear that there was a strong sense of incongruity. However, by using the fluorescent lamp 7 that emits a mixed white light of three wavelengths as in the present embodiment, the lamp image reflected on the globe body 22 becomes whitish, and the container specific processing can be made preferable.

  The brightness of the globe body 22 in the lighting state of the luminaire 1 is brightest immediately below the fluorescent lamp 7, and the brightness decreases as it approaches the overhanging edge 22a. However, as described above, the surface of the long globe presser 31 used for pressing the overhanging edge 22a is coated with a highly reflective paint. Thereby, the light reflected by the inner surface of the glove body 22 and incident on the glove holder 31 is reflected below the glove holder 31. Therefore, the distribution of brightness along the width direction of the glove body 22 is improved, and in this respect, the container can be made preferable.
