Description

  The present invention relates to a lighting device in a passenger room using a sheet-like organic EL (organic electroluminescence) of a railway vehicle, particularly a railway vehicle, as a lighting tool.

  Conventionally, in-vehicle lighting of a railway vehicle is generally indirect lighting in which a fluorescent lamp is attached to a ceiling surface of a passenger cabin as a lighting fixture via a receiver and the fluorescent lamp is covered with a cover.

  In such a fluorescent lamp illumination, since the illumination unit including the fluorescent lamp is heavy, it is necessary to increase the rigidity of the mounting portion of the illumination unit by providing a reinforcing member. Furthermore, it is necessary to provide a receiver for attaching the fluorescent lamp, which causes an increase in the vehicle weight.

  The mainstream is to install the air conditioner in parallel with the air blower line, but it is necessary to install the lighting fixture in consideration of the balance with other ceiling equipment. It takes time to adjust the time, which increases man-hours.

  Furthermore, when the fluorescent lamp is mounted in an exposed state, it may be broken and scattered by dropping.

  Incidentally, in recent years, from the viewpoint of energy saving and CO2 reduction, it has been proposed to use a cold cathode (CCFL) fluorescent tube as an illuminator replacing the fluorescent lamp (see, for example, Patent Document 1).

  The cold cathode fluorescent tube is a light emitting tube that is a thin fluorescent tube, and is a fluorescent light emitter by the same discharge as a normal fluorescent lamp, but since it does not use a filament, it generates less heat and flickers with high-frequency lighting. Although it has the merit of being kind to eyes, since it is a light-emitting tube, it has the same problem as the ordinary fluorescent lamp as described above.

  Moreover, what has arrange | positioned the planar illumination part using several LED for illumination on the lower surface of a cargo rack main body is proposed (for example, refer patent document 2).

JP 2001-327836 A JP 2005-324694 A

  In the thing of patent document 2, since several LED for illumination is used, it is expensive, and since a reflective diffuser plate and a diffused illumination plate are used, a structure is complicated and it is disadvantageous also in terms of weight. Due to the restrictions, the degree of freedom of layout is low.

  The present invention provides a railroad vehicle that can reduce the weight of a lighting fixture and increase the degree of freedom of layout by using cabin lighting that uses an organic EL lighting fixture that can be used as a surface light source (diffuse light source) that shines as a whole. The purpose is to provide.

  The invention of claim 1 is a railway vehicle in which a lighting device is provided on a ceiling surface of a guest room, and the lighting device is a sheet-like organic electroluminescence type lighting device, and is arranged along the surface of the ceiling surface. It is attached to a ceiling surface, The surface of the said lighting fixture is covered with the protective layer in the attachment state, It is characterized by the above-mentioned. In addition, attachment to the ceiling surface of a lighting fixture is performed using well-known attachment means, such as adhesion | attachment and screwing.

  In this case, since the organic EL that can be used as a surface light source (diffusion light source) is used as the illuminating device, the weight of the illuminating device is reduced as compared with the case of using the lighting LED as well as the fluorescent lamp. In addition, since it is not necessary to provide a reinforcing member or a catch for mounting, it is possible to reduce the weight of the lighting fixture and simplify the mounting, which is advantageous in reducing the weight of the vehicle.

  And since it is only attached to the ceiling surface along the ceiling surface of the guest room, it is not necessary to install it in consideration of the positional relationship with other ceiling equipment, the burden on the operator at the time of installation is reduced, and the layout The degree of freedom increases.

  In this case, as described in claim 2, the lighting device is configured such that a sheet-like organic electroluminescence is bonded to a mounting plate, and the mounting plate is attached to a ceiling surface. Preferably, as described in claim 3, the lighting device or the mounting plate is mounted in a recess formed in the ceiling surface, and the entire lighting device is provided in the recess. Good.

  As described above, the present invention uses an organic EL lighting fixture instead of a fluorescent lamp as a lighting fixture on the ceiling surface in the cabin. Can do. In addition, since there is no need to reinforce or attach the attachment portion, this is also advantageous in terms of weight reduction. In addition, since the OLED lighting fixtures are simply installed along the ceiling surface of the guest room, there is no need to adjust the balance with other ceiling equipment, reducing the installation man-hours and the freedom of layout. Also gets higher.

It is sectional drawing of the roof part of the rail vehicle which concerns on this invention. It is an A direction arrow directional view of FIG. It is a schematic sectional drawing which shows the lighting fixture attachment structure in the rail vehicle which concerns on this invention. It is a schematic sectional drawing which shows another embodiment of the said lighting fixture attachment structure. It is a schematic sectional drawing which shows another embodiment of the said lighting fixture attachment structure.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the air-conditioning duct 2 disposed in the roof structure 1 of the railway vehicle is provided on both the left and right sides of the cross-flow fan 4 for stirring the air in the passenger compartment section S1, and this cross-flow fan. 4 is supplied from the blow-out window portion 5 into the cabin space S1 through the air conditioning plate 6a which is a part of the ceiling plate 6.

  On the outside in the left-right direction of the air conditioning duct 2, organic electroluminescence (organic EL) is provided as a lighting fixture 7 for cabin lighting. This organic EL lighting device 7 is a rectangular sheet having flexibility, and has a thickness of about 2 to 3 mm.

  Specifically, the lighting fixture 7 is attached to the lower surface (ceiling surface) by bonding via an adhesive layer 9 so as to be along the lower surface (the surface to be the ceiling surface) of the ceiling plate 8, and the lighting fixture is in the attached state. The surface of 7 is covered with a protective layer 10. Through the small hole 8a formed in the ceiling plate 8, the connecting projection 7a of the illuminator 7 is inserted into the ceiling space S2 above the ceiling plate 8, from which various lighting control devices and power supplies (not shown) are connected. The wiring 12 for connection to the terminal extends in the ceiling space S2.

  The protective layer 10 is made of a transparent or translucent coating material such as glass or polycarbonate, and is provided to prevent contamination and contamination. Moreover, the sealing agent 13 is arrange | positioned around the lighting fixture 7, and the waterproof performance is ensured.

  By adopting the illumination fixture 7 having such a structure for illumination in the passenger cabin space S1 of the railway vehicle, the weight can be reduced as compared with the case where a conventional illumination fixture such as a fluorescent lamp is used. Moreover, since the lighting fixture 7 is made of organic EL, a mounting portion for reinforcing the lighting fixture 7 or a receiving fixture for mounting the lighting fixture is not necessary. It is advantageous for weight reduction.

  Further, since only the lighting fixture 7 is provided along the ceiling surface of the guest room space S1, there is no need to adjust the balance such as the positional relationship with other ceiling devices, the number of mounting steps can be reduced, and the degree of freedom in layout. Also gets higher.

  In addition, the lighting fixture 7 can be attached simply by providing the small hole 8a without providing a large opening in the ceiling plate 8. Therefore, it is necessary to reinforce the periphery of the opening as in the case of providing a lighting fixture such as a conventional fluorescent lamp. In addition, since it is not necessary to consider the decrease in rigidity due to the provision of the opening, it can be attached by bonding as described above without being greatly restricted with respect to the installation location.

  That is, since the illuminating device 7 can be directly installed even on the portion of the ceiling plate 8 that could not be provided from the viewpoint of lowering the rigidity, the installation position of the illuminating device 7 for the ceiling is determined. , Layout flexibility is increased. In addition, the structure can be simplified, which is advantageous in terms of cost and work.

  Moreover, since the lighting fixture 7 is composed of an organic EL, the color and display information can be easily changed by control signals from various lighting control devices (not shown), and between the roof structure 1 and the ceiling plate 8. Since the various lighting control devices for the lighting fixture 7 housed in the ceiling space S2 can be configured to be small, the height of the cabin space S1 can be made higher than when a conventional fluorescent lamp or the like is used. This can be increased, which is advantageous for expanding the cabin space S1.

  As described above, instead of being directly attached to the ceiling plate 8 via the adhesive layer 9, as shown in FIG. 3, it is also possible to screw using a mounting plate.

  In that case, the lighting fixture 7 is attached to a mounting plate 21 having a size corresponding to the size of the lighting fixture 7 by bonding or the like, and the peripheral portion of the mounting plate 21 is attached to the ceiling plate 8 with a plurality of screws 22. The lighting fixture 7 can be attached to the ceiling board 8 by screwing. A mounting screw seat 23 is provided on the inner surface side of the screwed portion of the ceiling plate 8. In addition, the mounting plate 21 is also formed with through holes 12a through which the connecting projections 7a of the lighting fixture 7 pass, corresponding to the small holes 8a, like the small holes 8a of the ceiling plate 8. Other configurations are the same as those shown in FIG.

  Further, as shown in FIG. 4, a recess 8A having a size corresponding to the mounting plate 21 is formed in the ceiling plate 8, and the lighting fixture 7 is attached in the concave portion 8 </ b> A, whereby the ceiling plate by the lighting fixture 7 is provided. It is also possible that no protruding portion from the outer surface of 1 is formed. Other configurations are the same as those shown in FIG. When the lighting fixture 7 is directly bonded, the recess formed in the ceiling plate 8 may be sized corresponding to the lighting fixture 7 and can be screwed without providing the recess 8A. Of course.

  In this case, a recess structure member having a recess 31A in the center so as to form an opening 8B in the ceiling plate 8 and close the opening 8B, as shown in FIG. It is also possible to join the peripheral flange portion 31 </ b> B of 31 to the upper side surface of the ceiling plate 8 and attach the lighting fixture 7 and the mounting plate 11 in the recess 31 </ b> A of the recess structure member 31. A mounting screw seat 23 is provided at a predetermined position on the upper surface side of the recess 31 </ b> A of the recess structure member 31.

  The present invention is not limited to the embodiment described above, and can be implemented with the following modifications.

  (i) The organic EL type lighting device or the mounting plate can be attached by using a suction means using a suction force of a magnet (for example, a plate magnet).

  (ii) Not only existing railroad vehicles and new railcars, but also the same type of railcars can be manufactured with a simple design change when repeatedly manufacturing some of the specifications. That is, since it is not necessary to provide an opening for attachment in the ceiling plate 8, it can be handled with the same wiring route as that of the same type of railway vehicle manufactured previously, and there is no need to change the wiring route.
