Hereinafter, various embodiments representing the present invention will be described with reference to the drawings.
1 to 9 show a first embodiment of the present invention.
As shown in FIG. 1, the lighting device 10 includes a casing 11 that is attached to the ceiling side and that opens downward and has an inner opening. Direct light from the light source 20 assembled in the casing 11 is reflected on the inner side of the casing 11. The lower part of the casing 11 is indirectly illuminated by the reflected indirect light. Such an illuminating device 10 is disposed on the ceiling 3 in the passenger cabin 2 of the vehicle. Hereinafter, an example applied to the railway vehicle 1 will be described.

  As shown in FIG. 9, the lighting device 10 is installed on the ceiling portion 3 in the passenger cabin 2 of the railway vehicle 1, and is installed so as to extend in the front-rear direction along the ceiling portion 3. The lighting device 10 is sequentially connected so that a plurality of units extending in the longitudinal direction are arranged in a line. The casing 11 constituting the main part of the unit is installed on the ceiling 3 with its opening side facing downward. A pair of concave grooves 3a and 3a are formed in the ceiling portion 3 so as to be symmetrical with respect to a center line extending in the front-rear direction, and the casing 11 is embedded in each concave groove 3a.

  As shown in FIGS. 1 to 5, an extending portion 14 that integrally extends downward is formed along a central portion 12 that is a predetermined location inside the casing 11. The extending portion 14 is a part that blocks the light source 20 in a predetermined light distribution direction and blocks a part of an irradiation range of the direct light from the light source 20 that goes downward. Such a casing 11 has a shape that can be easily extruded using a metal such as aluminum, a nonflammable resin, or the like.

  More specifically, the casing 11 has a shape of the same cross section extending in a long shape, and both side portions 13 and 13 extending in both sides from the central portion 12 extending in the longitudinal direction and extending in parallel with each other are gradually curved downward. An arc-shaped cross section is formed, and the inner side of the arc-shaped cross section is a reflecting surface 13a. As described above, the casing 11 includes a pair of left and right reflecting surfaces 13a in the cross-sectional shape. Each reflecting surface 13a is subjected to a surface treatment that increases light reflection efficiency. Specifically, for example, a white paint may be applied or mirrored.

  The extending portion 14 that hangs down from the central portion 12 of the casing 11 has the same cross-sectional shape extending in the longitudinal direction of the casing 11 and is integrally formed with the casing 11. The extending portion 14 has an attachment space 17 in which accessories other than the light source 20 can be attached, in addition to a portion where the light source 20 described later is assembled. Specifically, the extended portion 14 hangs from the central portion 12 so that the pair of side wall ribs 15 and 15 are symmetrically downward and spaced apart from each other at an angle upward from the vertical, and is curved upward at each lower end. The bottom wall ribs 16, 16 having a circular arc cross section are connected.

  A gap between the opposing edges of the pair of bottom wall ribs 16, 16 in the extended portion 14 becomes an opening groove 17 a of the mounting space 17, and the pair of side wall ribs 15, 15 and the pair of bottom wall ribs 16. , 16 is an inner space 17b of the mounting space 17. As described above, the mounting space 17 of the extending portion 14 includes the opening groove 17a facing downward and the internal space 17b extending inside the opening groove 17a, and a part of the accessories other than the light source 20 is stored in the internal space 17b. It is possible to expose the other part of the accessory below the opening groove 17a. The hanging advertisement 30 as an example of the accessory will be described later.

  Moreover, the lower end edge of both the side parts 13 and 13 of the casing 11 and the upper end edge of both bottom wall ribs 16 and 16 of the extension part 14 can irradiate the direct light from the light source 20 described below from the side. They are arranged in a positional relationship (see FIG. 8). Here, a space between the central portion 12 of the casing 11 and the bottom wall rib 16 of the extending portion 14 is a storage space for the light source 20, and the light source 20 extends in the longitudinal direction along the outer surfaces of the pair of side wall ribs 15, 15. It is assembled to line up. In addition, although the kind of light source 20 is not specifically limited, It is preferable that it is LED. LEDs have the advantages of small size, low power consumption, and long life.

  The light source 20 in the present embodiment is obtained by fixing a plurality of surface-mounted LED chips 22 arranged at equal intervals on a substrate 21 extending in a narrow width. Here, the LED chip 22 is general and will not be described in detail, but a type that emits light within a radiation range of a predetermined angle around an optical axis orthogonal to the substrate 21 is used. The emission color of the LED chip 22 can be arbitrarily selected. One surface of the substrate 21 is a mounting surface, and a wiring circuit to which the LED chip 22 is electrically connected is formed on the mounting surface. A phosphor layer may be laminated on the mounting surface of the substrate 21 so as to cover the LED chip 22.

  As shown in FIG. 1, the substrate 21 of the light source 20 is assembled along the outer surface of each side wall rib 15 so as to face sideways at an upward angle. More specifically, a pair of rail grooves 18a, 18a facing vertically are formed on both sides of the central portion 12 where the upper ends of the side wall ribs 15 are continuous and inside the bottom wall ribs 16 where the lower ends of the side wall ribs 15 are continuous. The both side edges of the substrate 21 are slidably fitted between the rail grooves 18a.

  A protective cover 23 is attached in front of the light source 20. The protective cover 23 is formed in a flat plate shape having the same shape as the substrate 21 and extending in a narrow width. The material of the protective cover 23 is not particularly limited as long as it is a light transmissive material such as an acrylic resin or a PC resin. However, it is preferably a synthetic resin instead of glass for reasons such as ease of processing. The protective cover 23 may be colorless and transparent, or may be colored and transparent, or the protective cover 23 may contain a light diffusing agent to actively diffuse light within the protective cover 23.

  As shown in FIG. 1, the protective cover 23 is mounted between the central portion 12 of the casing 11 and the inside of each bottom wall rib 16 so as to surround the substrate 21 of the light source 20 from the outside. More specifically, a pair of rail grooves 18b, 18b that are vertically opposed to each other are provided below the both ends of the central portion 12 and near the upper edge of each bottom wall rib 16, and between each rail groove 18b. The both side edges of the protective cover 23 are slidably fitted. Here, the protective cover 23 is located inside the upper edge of each bottom wall rib 16.

  As described above, the bottom wall rib 16 of the extending portion 14 extends at least to a position that overlaps the entire area of the protective cover 23 in the vertical direction. (Including objects). Here, since the protective cover 23 forms a vertical plane with respect to the horizontal plane, it has a structure in which a passenger's baggage or the like is difficult to directly contact from below. The debris will go inward and will be received on the bottom wall rib 16.

  In the mounting space 17 in the present embodiment, a hanging advertisement 30 is separately attached as an accessory other than the light source 20 (including the protective cover 23). Here, the hanging advertisement 30 is an advertisement using horizontally long rectangular paper suspended from the ceiling side, and the contents of the advertisement are described on one side or both sides thereof. Generally, the upper end side of the hanging advertisement 30 is held by the holding means, but the holding means is attached in a state of being accommodated in the internal space 17b of the mounting space 17, and is lower than the upper end side of the hanging advertisement 30. Is in a state where it hangs downward from the opening groove 17 a of the mounting space 17.

  Note that the hanging advertisement 30 does not need to have a length over the entire length of the lighting device 10, and uses a plurality of advertisements (see FIG. 2) divided into appropriate lengths, or covers the entire length of the lighting device 10. One advertisement with a length (see FIG. 7) may be used. The content of the advertisement is not particularly limited. For example, advertisements of the railway company itself or its affiliates, advertisements of stores (department stores, specialty stores, etc.) along the railway, or magazines (monthly magazines, weekly magazines, etc.) It is a wide variety.

  The holding means for the hanging advertisement 30 in the present embodiment includes a stopper 31 that clamps the upper end of the sheet. As shown in FIG. 6, the stopper 31 is formed by connecting an angle member having an L-shaped cross section through a shaft 32 so as to be openable and closable, and at least one inner surface of a pair of sandwiching pieces 33 and 33 to be opened and closed has a paper surface. A protrusion 33a for stopping is provided. Such a stopper 31 is not provided with a means for urging in a closed state in which the respective holding pieces 33 are combined, and a pair of upper end pieces 34, 34 that are horizontally connected to each other in the closed state are provided in the state. The space 17 is held by being housed in the internal space 17b.

  Specifically, as shown in FIG. 1, a pair of rail grooves 18c and 18c facing left and right are provided inside the bottom wall ribs 16 where the lower ends of the side wall ribs 15 of the extending portion 14 are continuous. If each side edge of a pair of upper end pieces 34, 34 that are horizontally connected to each other between the rail grooves 18c and that are closed with the hanging advertisement 30 interposed therebetween is slidably fitted, The closed state is maintained. Note that the length of the stopper 31 does not need to be matched to the entire length of the lighting device 10 as in the advertisement, and those divided in correspondence with a plurality of advertisements (see FIG. 2) may be connected to each other in the longitudinal direction. .

  In the illuminating device 10 as described above, as shown in FIG. 8, the direct light irradiated in the left and right directions from the light source 20 is reflected by the reflecting surface 13 a of the side portion 13 of the casing 11 on the side facing the light source 20. It is reflected and set so as to be directed to the interior 2 in the lower room. However, a part of the indirect light reflected by each reflecting surface 13a is blocked from being irradiated downward along with the direct light from the light source 20 by the extending portion 14.

  Of the direct light from the light source 20, the direct light directed laterally from between the lower end edge of the both side portions 13 of the casing 11 and the upper end edge of the bottom wall rib 16 of the extending portion 14 is generated in the cabin 2. It is set so as to reach the vicinity of the boundary between the ceiling portion 3 and the side wall surface portion 4. A face advertisement 6 is developed along the boundary between the ceiling part 3 and the side wall part 4, and the direct light emitted laterally from the gap of the casing 11 reaches the entire surface of the face advertisement 6.

Next, the effect | action of the illuminating device 10 which concerns on 1st Embodiment is demonstrated.
As shown in FIG. 9, the present lighting device 10 embeds a casing 11 in a concave groove 3 a in a ceiling portion 3 in a passenger cabin 2 of a railway vehicle 1 with its opening side facing downward. The illuminating device 10 is attached to the concave groove 3a on the upper end surface of the central portion 12 of the casing 11 through fixing means such as a mounting bracket or a screw. Here, by connecting a plurality of casings 11 forming a unit of the lighting device 10, the casing 11 can be appropriately extended to a desired length.

  In the present embodiment, the lower end edges of the side portions 13 of the casing 11 are at the same height as the reference surface of the ceiling portion 3, so that a sense of unity between the lighting device 10 and the ceiling portion 3 is enhanced. In addition, since the pair of lighting devices 10 are installed so as to be symmetrically arranged with the center line of the ceiling 3 as the axis of symmetry, the cabin 2 can be illuminated in a wide range from both the left and right sides with a good balance. Note that the left and right illumination devices 10 may be individually controlled to be lit.

  Moreover, in the present lighting device 10, by using the LED chip 22 as the light source 20, desired brightness can be obtained with low power consumption. Further, the entire apparatus can be reduced in size as compared with a fluorescent lamp or the like, the feeling of pressure on passengers is less, and the shape can be freely designed in accordance with the cabin 2. Moreover, the casing 11 which forms the main part of the unit has a shape that can be easily extruded by a metal such as aluminum, and the manufacturing cost can be reduced.

  As shown in FIG. 8, the light source 20 is assembled to the extending portion 14 of the casing 11 mainly in a light distribution direction in which light is emitted sideways. Of the direct light from the light source 20, the light upward from the horizontal plane is reflected downward by the reflecting surface 13 a inside the both side portions 13, 13 of the casing 11. The cabin 2 is illuminated by the reflected indirect light. In addition, part of the irradiation range of the direct light from the light source 20 that goes downward from the opening of the casing 11 is blocked by the extending portion 14.

  Thereby, the direct light from the light source 20 does not reach the cabin 2 (particularly the region where the seat 5 is located), and the cabin 2 is illuminated by the indirect light reflected and diffused by the reflecting surface 13a as described above. Therefore, the glare in the passenger compartment 2 can be reduced and the entire room can be softly illuminated, and a calm atmosphere is created. Here, by devising the shapes of the extending portion 14 and the reflecting surface 13a, various light distribution controls according to the purpose and application in the cabin 2 are possible. As specific light distribution control, it is conceivable to uniformly irradiate the cabin 2 or to brighten specific portions such as the passage 2 and the seat 5 in the cabin 2.

  Moreover, the extending portion 14 is not only a part for assembling the light source 20 or a part for controlling light distribution for blocking direct light or indirect light, but it is possible to attach accessories other than the light source 20. A mounting space 17 is provided. This mounting space 17 can be effectively used for a purpose for mounting various accessories as a vacant space secured in advance. In particular, in the casing 11 according to the present embodiment, a dead space is inevitably generated between the pair of side wall ribs 15, 15 to which the light source 20 is attached because of the design of the light distribution direction of the light source 20. The mounting space 17 can be utilized.

  As shown in FIG. 1, the mounting space 17 includes an opening groove 17 a facing downward and an internal gap 17 b that expands inside the opening groove 17 a. Thereby, while attaching a part of accessory to the state accommodated in the internal space | gap 17b, the attachment aspect which exposes the other part of an accessory below the opening groove | channel 17a is attained. Here, specifically, for example, the hanging advertisement 30 is suitable as an accessory. In the present embodiment, the clasp 31 that is the holding means on the upper end side of the suspended advertisement 30 is attached in a state of being accommodated in the internal space 17b of the mounting space 17, and the paper surface below the upper end side of the suspended advertisement 30 is attached. Is suspended downward from the opening groove 17a.

  As shown in FIG. 6, the stopper 31 is formed by connecting an angle member having an L-shaped cross section via a shaft 32 so as to be openable and closable, and an upper end edge of the hanging advertisement 30 is interposed between a pair of sandwiching pieces 33 and 33. Close to pinch. In this closed state, if the both side edges of the pair of upper end pieces 34, 34 that are horizontally connected are inserted between the rail grooves 18 c in the mounting space 17 from one end side of the casing 11, the extending portion 14 can be easily formed. The hanging advertisement 30 can be attached to the door. When the suspended advertisement 30 is removed from the extended portion 14, it is only necessary to remove the stopper 31 from one end of the casing 11, and it is possible to easily replace the suspended advertisement 30 with other suspended advertisements 30 on a regular basis. .

  Thereby, the illuminating device 10 can be utilized also as an advertising medium, and the advertisement can be brightly illuminated by the nearby illumination. That is, the indirect light reflected by the reflecting surfaces 13a on the both side portions 13 and 13 of the casing 11 intersects at a position below the extending portion 14, but is blocked by the hanging advertisement 30 and Both sides can be illuminated brightly (see FIG. 8). As described above, by adding the added value of an advertising medium to the lighting device 10, it is possible to increase the commercial value of the lighting device 10 itself and to obtain advertising revenue.

Between the ceiling portion 3 and the side wall surface portion 4 of the cabin 2 as direct light. Therefore, the lighting device 10 not only irradiates the area where the seat 5 is located in the cabin 2 as in the conventional case, but particularly in the vicinity of the boundary between the ceiling portion 3 and the side wall surface portion 4 in the cabin 2, that is, generally an advertisement on a window. The space can be directly irradiated with light.

  As a result, as shown in FIG. 9, along the boundary between the ceiling portion 3 and the side wall surface portion 4, the entire face advertisement 6, particularly the ceiling surface, developed so as to bend from the reference surface of the ceiling portion 3 to the side wall surface portion 4. The part along the line can also be highlighted by direct light. Moreover, it becomes possible to make it light distribution which irradiates the whole surface of the face value advertisement 6 by one lighting device 10, and it becomes easier to see the face value advertisement 6 from the passengers without causing a group, a shadow, a line or the like in the face value advertisement 6. .

  Further, the casing 11 is provided with a protective cover 23 that covers the light source 20 from the outside. Therefore, the light emitted from the light source 20 is transmitted through the protective cover 23, whereby the luminance of the light source 20 is reduced and excessive strong light irradiation can be prevented. In addition, it is possible to protect the light source 20 by preventing contact with other objects that may cause a failure of the light source 20. Here, the protective cover 23 is attached in a state perpendicular to the horizontal plane, and an object from below may be touched, but it is unlikely that an impact is strongly applied to the protective cover 23 from the vertical direction. . Further, dust does not collect on the vertical surface of the protective cover 23.

  If the protective cover 23 is made of a synthetic resin, it will not be easily damaged like a fluorescent tube even if a passenger's baggage hits it. However, if the protective cover 23 is unexpectedly removed or damaged, The debris is received by the bottom wall rib 16 of the extending portion 14 and does not fall into the cabin 2. The extension part 14 is integrally formed with the casing 11 and there is no possibility that the extension part 14 will come off like a separate member that is detachable. The bottom wall rib 16 of the extending portion 14 extends at least to a position that overlaps the entire area of the protective cover 23 in the vertical direction. When the protective cover 23 is damaged, it is formed in a shape that receives the fragments. ing.
