Description

The present invention relates to a lighting fixture mounting member to be attached to a lighting fixture, and more particularly to a lighting fixture mounting member to be attached to a ceiling lighting device having an existing linear light source.

In stores, offices, factories and the like, lighting fixtures in which two straight tube fluorescent lamps are arranged side by side are often used. In recent years, for only one of the two fluorescent lamps, a reflector is retrofitted between the reflecting surface of the lighting fixture and the fluorescent lamp to improve the reflection efficiency of the fluorescent lamp light, and the other one is removed. Thus, power costs are reduced (for example, Patent Document 1). In this case, there may be used a lighting fixture mounting member in which a cover member that covers the lighting fixture is made of the same material as the reflector that is attached to the periphery of the fluorescent lamp in order to hide an unnecessary fluorescent lamp portion.

By the way, it is known to use a thermoplastic resin sheet having fine bubbles or pores inside as the reflecting plate (for example, Patent Document 2). This thermoplastic resin sheet has a high reflectance, but its flame retardancy is inferior to that of a metal reflector. Therefore, a reflection plate in which a thin metal plate is bonded to a thermoplastic resin sheet having fine bubbles or pores inside may be used.

However, when the cover member that covers the luminaire is formed integrally with the reflector, the boundary between the portion that reflects the light from the light source and the portion that becomes the cover member must be folded. What stuck the board had the problem that a process was difficult. Moreover, since the thing which bonded the metal plate to the thermoplastic resin sheet will be used also for the part used as a cover member, since weight becomes heavy, the danger that a product will fall after attachment will also become high.

Therefore, the present invention includes a reflector for reflecting light from a linear light source and a cover member that covers the luminaire, and is an attachment member for a luminaire that is attached to the luminaire, and includes a reflector near the linear light source. It aims at providing the attachment member for lighting fixtures which is easy to manufacture and lightweight while ensuring a flame retardance.

In order to achieve the above-described object, a mounting member for a lighting fixture according to the present invention is a mounting member for a lighting fixture that is attached to a lighting fixture having a linear light source, covers the linear light source, and And a cover member that covers the lighting fixture. The reflector is laminated on the thermoplastic resin sheet having fine bubbles or pores inside, and on the back surface of the thermoplastic resin sheet. The cover member has an opening at a position corresponding to the linear light source, and the reflection plate is attached to the opening.

In the above-described lighting fixture mounting member, the cover member may be formed of a thermoplastic resin sheet having fine bubbles or pores therein.

Moreover, in the above-described lighting fixture mounting member, the cover member is provided with a bent portion in which an end portion of the opening portion is bent along the longitudinal direction of the linear light source, and the bent portion and the reflecting plate are provided.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 4.

The mounting member 1 for lighting fixtures according to the present embodiment is to be attached to a lighting fixture having a linear light source such as an existing straight tube fluorescent lamp. The luminaire A has, for example, a housing A1 embedded in the ceiling and opened on one surface, and two linear light sources are accommodated in the housing A1. In addition, the lighting fixture A attaches the fixture for lighting fixtures which concerns on this Embodiment,
Energy saving can be achieved by removing one linear light source and attaching a simulation tube A2 (so-called dummy tube) for energization instead or changing the inverter to one lamp.

The lighting fixture mounting member 1 includes a reflecting plate 2 that covers the linear light source A3 and reflects light from the linear light source A3, and a cover member 3 that covers the lighting fixture A.

The reflection plate 2 has a thermoplastic resin sheet 4, and the thermoplastic resin sheet 4 has fine bubbles or pores having an average cell diameter of 50 nm or more and 50 μm or less inside. The bubbles or pores do not have to be circular, and may be flat or needle-like. As such a thermoplastic resin sheet 4, for example, an extruded sheet of polyethylene terephthalate is impregnated with carbon dioxide under high pressure and then heated and foamed. The foamed plastic sheet has an internal cell diameter of 50 μm or less. There is a light reflection sheet (for example, MCPET manufactured by Furukawa Electric Co.
Registered trademark)). Further, another preferred example of the thermoplastic resin sheet 4 is a thermoplastic resin sheet containing a filler, in which a large number of voids are formed with the filler as a core. In this case, the thermoplastic resin sheet containing the filler is formed of an unstretched sheet containing the filler, and the unstretched stretched sheet is stretched to form a porous stretched sheet in which a large number of voids are formed using the filler as a core. It is preferable that As the material of the thermoplastic resin sheet 4, various materials can be exemplified, but polyester, polyphenylene sulfide, polypropylene, and cyclopolyolefin are preferable because of good heat resistance and impact resistance. In the resin used for the thermoplastic resin sheet 4, additives such as an antioxidant, an ultraviolet ray inhibitor, a lubricant, a pigment, and a reinforcing agent can be appropriately added. Moreover, you may shape | mold the coating layer containing these additives on the thermoplastic resin sheet 4. FIG. In particular, when the linear light source A3 is a cold cathode tube, it is necessary to add or coat an ultraviolet ray preventing agent. The thickness of the thermoplastic resin sheet 4 is an appropriate design matter, but 0.5 m
It is preferable that it is m-3.0mm. If it is too thick, the weight increases, and if it is too thin, it is easy to bend and impairs practicality in terms of shape retention.

A metal layer 5 is laminated on the back surface of the thermoplastic resin sheet 4 which is opposite to the surface serving as the reflection surface. Although the formation method of the metal layer 5 is not specifically limited, Preferably, it is good to make it laminate | stack on the thermoplastic resin sheet 4 by bonding a metal thin plate. Although a metal thin plate is not specifically limited, For example, an aluminum plate, a steel plate, a copper plate etc. are mentioned, Since it is lightweight and cost is also comparatively cheap, it is preferable to use an aluminum thin plate. The bonding of the thin metal plate to the thermoplastic resin sheet 4 may be performed by bonding with an adhesive, or may be heat-sealed without using an adhesive. As the adhesive, an epoxy compound-based or urethane compound (isocyanate) -based adhesive or the like can be used, but is not limited thereto. The thickness of the metal layer 5 is an appropriate design matter, but is preferably 0.08 to 1.5 mm.
If the thickness is too thick, the weight increases, and the work at the time of attachment becomes complicated. If the thickness is too thin, the effect of flame retardancy is not sufficient.

The reflection plate 2 is formed by forming an arch shape of a thermoplastic resin sheet 4 on which rectangular metal layers 5 are laminated, and the concave surface is a reflection surface. There is no limitation in this molding method, for example, press molding,
It can be formed by bending or the like. More specifically, for example, as shown in FIG. 2, the metal layer 5 is laminated along a folding line 10 formed in parallel with both longitudinal sides of the thermoplastic resin sheet 4 on which the metal layer 5 is laminated. The thermoplastic resin sheet 4 can be bent into an arch shape. In addition, when the concave curve 10 is provided in the reflective surface or back surface of the reflecting plate 2, the bending workability is good. The intervals of the folding lines 10 may be equal intervals or different intervals as appropriate. The number of folding lines 10 is not particularly limited.

1 and 3, the cover member 3 is made of, for example, a rectangular thermoplastic resin sheet, and an opening 6 is provided at a position corresponding to the linear light source A3 of the thermoplastic resin sheet. Yes. The material of the cover member 3 is not limited to the thermoplastic resin sheet, but the weight is reduced by using the same material as the thermoplastic resin sheet 4 having fine bubbles or pores inside the reflector 2. In addition, when attached to the ceiling, when viewed from below, there is continuity with the reflecting surface of the reflecting plate 2 and the appearance is good. The opening 6 is a linear light source A3.
The reflected light obtained by reflecting the light from the light source and the light from the linear light source A3 by the reflecting plate 2 may be opened to such an extent that the light is sufficiently emitted toward the room.

At the position corresponding to the simulated tube A2 of the cover member 3, a blindfold 7 is provided adjacent to the opening 6 so as to cover the simulated tube A2 and make it invisible. The blindfold 7 is formed by providing a predetermined area in the thermoplastic resin sheet 4 where the opening 6 is not provided.

The cover member 3 has a bent portion 8 formed by bending the end of the opening 6 on the longitudinal direction side along the longitudinal direction. The bent portion 8 is provided with a notch 9 for turning back the bent portion 8 on the extension line of the side on the direction orthogonal to the longitudinal direction of the opening 6, and a folding line 11 is provided at a place where the bent portion 8 is to be turned. By bending along the folding line 11, it can be easily molded.

As shown in FIG. 4, the lighting fixture attachment member 1 is configured by attaching the end portion on the longitudinal direction side of the reflection plate 2 to the bent portion 8 of the cover member 3. Although there is no limitation in the method of attaching the edge part of the reflecting plate 2 to the bending part 8, it is good to make it adhere using a double-sided adhesive tape. You may attach the edge part of the reflecting plate 2 to the bending part 8 with an adhesive agent, an adhesive, an adhesive tape, a mechanical fastener, a magnet etc. besides a double-sided adhesive tape.

1 shows an example in which the reflecting surface side of the end of the reflecting plate 2 is attached so as to be in contact with the bent portion 8 of the cover member 3, but the reverse side, that is, the metal layer 5 side is in contact with the bent portion 8. You may attach as follows. The one attached so that the reflecting surface side is in contact with the bent portion 8 of the cover member 3,
When it is attached to the luminaire A, it is preferable because the reflecting plate 2 is firmly supported from below by the cover member 3. However, even if the reflecting plate 2 is attached so that the back side is in contact with the bent portion 8, the reflecting plate 2 is Since it tries to bend back in the direction in which the arch shape opens, and the bent portion 8 tries to bend back in the direction opposite to the folded direction, the reflector 2 and the bent portion 8 are pressed against each other, so that they are firmly fixed. Is done.

The attachment member 1 for lighting fixtures is attached to the lighting fixture A by the peripheral part of the cover member 3 being fixed to the housing A1 of the lighting fixture A. There is no limitation on the method of fixing the cover member 3 to the housing A1 of the lighting device A. For example, the cover member 3 may be screwed, or a claw-like locking piece attached to the cover member 3 may be used. The magnetic sheet may be locked to the cover member 3 with an adhesive tape and fixed to the housing of the lighting apparatus by magnetic force.

In the present embodiment, the lighting fixture mounting member attached to the lighting fixture A in which two linear light sources are arranged side by side has been described. However, the present invention is not limited to this, and three linear light sources are provided as shown in FIG.

In this case, openings 26 are provided at two positions on both ends of the cover member 23 corresponding to the linear light source B 3, and a middle region sandwiched between the openings 26 is a blindfold 27. The opening 26 is provided with a bent portion 28 in the same manner as described above, and the reflector 2 similar to that described above is attached to the bent portion 28. Of the three linear light sources, one positioned at one end may be replaced with a simulated tube, or two positioned at both ends may be replaced with a simulated tube. In this case, an opening may be provided in a portion corresponding to the position where the linear light source of the cover member is disposed, and a reflection plate may be attached to this opening.

Moreover, although this Embodiment demonstrated the attachment member for lighting fixtures applied to the lighting fixture embedded in the ceiling, it is applicable also to the lighting fixture projected from the ceiling. In this case, as shown in FIG. 6, the cover member 33 is formed in a box shape having a surface located on the ceiling side when the lighting fixture is mounted, and a linear light source C3 on the surface facing the opening surface. It is preferable to provide the opening 36 at a position corresponding to. In addition, the locking member 39 is formed by bending the peripheral edge of the cover member 33 on the opening surface side inward, and is inserted between the base (not shown) of the lighting fixture and the ceiling to be locked to the base.
