After mounting each lighting fixture on a ceiling support bar, a fall prevention fitting is attached to an end of the lighting fixture. An option such as a lighting cover can be attached via For this reason, when many luminaires are connected in series, a lot of labor is required for mounting the luminaires and mounting options such as a fall prevention fitting and a lighting cover.

  On the other hand, the continuous fluorescent lamp system described in Patent Document 2 is a hanging bracket configured by a pair of left and right holding pieces and a locking portion formed by bending the lower end portion of each holding piece toward the inside of the lighting fixture. In this system, a wiring duct is suspended and a lighting fixture is attached to the wiring duct. This system has made it possible to mount the lighting fixtures very efficiently when connecting a large number of lighting fixtures.

  However, the portion supported by the hanging metal fitting is in a state in which the holding piece or the engaging portion of the hanging metal fitting overlaps the opening side of the wiring duct. For this reason, in order to attach a member such as a reflector to the opening portion of the wiring duct, it is necessary to attach it in consideration of the thickness and position of the locking portion of the hanging bracket.

Therefore, the continuous fluorescent lamp system described in Patent Document 3 is a system that can be mounted without considering the thickness and position of the locking portion of the hanging bracket. In this system, a connecting rail for connecting the hanging bracket is provided on the upper surface of the wiring duct, and the connecting rail provided at the lower end of the hanging bracket is locked to the connecting rail to suspend the wiring duct. Adopted. As a result,
It is no longer necessary to consider the thickness and position of the latching portion of the hanging metal fitting, and it is possible to attach or detach any member over the entire opening of the wiring duct. However, since a wiring duct having a special structure having a connecting rail provided on the upper surface and a connecting metal fitting having a special structure adapted to the wiring duct are used, there is a disadvantage that the manufacturing cost increases.

  According to the present invention, in the case where straight pipe luminaires are connected continuously using a hanging bracket, the original purpose such as that a lighting cover can be reasonably continuously mounted without hindering the hanging bracket. Achieved.

  Examples of the present invention will be described below. The basic configuration of the illumination device of the present invention is composed of a lighting case 10, a reflector 20, a clip body 30, and a height adjuster 40 (see FIG. 1).

  The writing case 10 is a member having a hook shape with a bottom surface opened and bent inward along the side edge of the opening. Then, the reflector 20 is attached to the opening of the lighting case 10 that is suspended by the suspension bolt Q fixed to the ceiling or the like and directed downward (see FIG. 1). That is, after the lighting case 10 is continuously provided in the longitudinal direction, the reflector 20 is sequentially attached (see FIG. 10).

  The suspension fitting P used in the present invention is a fitting provided with a pair of left and right holding pieces P1 suspended by a suspension bolt Q, and a locking portion P2 in which the lower end of the holding piece is bent inward. Yes (see FIG. 1). And the bending piece 11 of the writing case 10 is latched by this latching | locking part P2. In the illustrated hanging bracket P, a holding claw P3 for holding the bent piece 11 is provided in the locking portion P2. The holding claw P3 is provided at the longitudinal end of the locking portion P2, and in particular, is formed at the opposite end at an oblique position of the opposite end of the locking portion P2 (see FIG. 1). And it is provided so that the bending piece 11 may be hold | maintained toward the inner side of the lighting case 10 (refer FIG. 7).

  The hanging metal fitting P is separated into right and left, and is connected by a bolt S penetrating the side surface of each holding piece P1 (see FIG. 1). Then, the suspension bolts Q are inserted through the portions where the upper end portions of the respective holding pieces P1 overlap, and are locked by the suspension nuts Q1. The suspension nut Q1 is inserted into the suspension fitting P from a substantially cross-shaped insertion port P4 formed on the upper side surface of one holding piece P1, and is formed on the upper end of the other holding piece P1. The suspension bolt Q is inserted into the portion P5, and the portion where the upper end portions of the respective locking portions P2 overlap is locked.

  At this time, the sealing body P6 which seals the insertion port P4 is provided, and it fixes to the latching | locking part P2 with the connection volt | bolt S (refer FIG. 1). By configuring the hanging bracket P in this way, the connection work is easy, and the fall can be prevented even by shaking such as an earthquake.

  The reflection plate 20 is a member disposed in the opening of the lighting case 10. A socket 50, a connector 60, and a mount base 70 are attached to the reflecting plate 20 (see FIG. 1). And the straight tube | pipe lamp R is installed in the lower surface of the reflecting plate 20 (refer FIG. 3).

  The clip body 30 is a member fixed to a rotating bolt 31 penetrating from the lower surface of the reflecting plate 20 to the upper surface, and is rotatably mounted together with the rotating bolt 31 on the upper surface of the reflecting plate 20 (see FIG. 3). The rotating bolt 31 is a bolt member that uses a square root bolt penetrating from the lower surface to the upper surface of the reflecting plate 20 and rotates the clip body 30 at the square root portion (see FIG. 1). Moreover, the latching | locking part 32 latched on the bending piece 11 upper surface of the lighting case 10 is provided in the longitudinal both ends of the clip body 30 (refer FIG. 2). The illustrated clip body 30 is formed with a dish-like base 34 through which the rotating bolt 31 passes, and locking portions 32 are provided at both ends of the base 34 (see FIG. 3). An insertion hole 33 is formed in the base 34 (see FIG. 2), and the base 34 is supported on the top of a projection 43 of a height adjuster 40 described later (see FIGS. 3 and 4). , The projection 43 is inserted into the insertion hole 33 (see FIG. 6).

  The height adjuster 40 is a member that supports the clip body 30 while adjusting the height of the clip body 30 when the clip body 30 rotates (see FIG. 3). In the height adjuster 40, when the reflector 20 is attached to the opening of the lighting case 10, the protrusion 43 is rotatably supported in a state where the clip body 30 is pushed up above the position of the bent piece 11. On the other hand, when the locking portion 32 of the clip body 30 rotates to above the bent piece 11 of the writing case 10, the crimping plate 41 pushes down the clip body 30 so that the locking portion 32 is locked to the bent piece 11. (See FIG. 6).

  The illustrated height adjuster 40 includes a support plate 42 that allows the rotating bolt 31 to pass therethrough, a protrusion 43 that projects from the support plate 42, and a force that constantly presses the clip body 30 downward from above the clip body 30. And a crimping plate 41 to be used (see FIG. 3).

  The support plate 42 is a member provided on the lower surface of the clip body 30 and provided with a protrusion 43 that rotatably supports the clip body 30 at a high position (see FIG. 4). Then, the insertion hole 33 into which the protrusion 43 is inserted is formed in the clip body 30 (see FIG. 2), and when the clip body 30 rotates and the locking portion 32 moves to above the bent piece 11, The protrusion 43 is configured to be inserted into the insertion hole 33 by the urging force of the pressure plate 41 (see FIG. 6).

  The crimping plate 41 uses a wave washer and is mounted between a fixing nut 44 screwed to the upper part of the rotating bolt 31 and the base 34 (see FIGS. 6 and 7). And when rotating the base | substrate 34 with the square root part of the rotation bolt 31, the crimping | compression-bonding board 41 always presses and urges | biases the base | substrate 34 downward.

  That is, when attaching the reflecting plate 20 to the opening of the storage body 10, the engaging portion 32 of the clip body 30 is set along the longitudinal direction of the reflecting plate 20 (see FIG. 2). At this time, the clip body 30 is in a state of rotating on the protrusion 43 of the support plate 42 (see FIG. 4). And after attaching the reflecting plate 20 to the opening part of the storage body 10, the clip body 30 is rotated with the rotating volt | bolt 31, and the latching | locking part 32 rotationally moves above the bending piece 11. FIG. At this time, the clip body 30 is pressed and urged downward by the elastic force of the crimping plate 41, the projection 43 of the support plate 42 is fitted into the fitting hole 33, and the locking portion 32 is locked on the bent piece 11. (See FIG. 6). In the figure, reference numeral 23 denotes an elastic plate such as a rubber plate, which is a member for increasing the fixing force of the reflecting plate 20.

  When the reflecting plate 20 is attached to a portion where the locking portion P2 of the hanging bracket P locks the bent piece 11 of the writing case 10, the thickness from the reflecting plate 20 to the bent piece 11 is equal to the thickness of the locking portion P2. The height increases (see FIG. 7). In this case, the clip body 30 supported by the protrusion 43 can be rotated to the top of the bent piece 11 by peeling off the elastic plate attached with the adhesive tape. And if it rotates to the position of the insertion hole 33, the latching | locking part 32 will be latched on the bending piece 11 in a high position with the urging | biasing force of the crimping | compression-bonding board 41. FIG. Therefore, the height adjusting tool 40 can always obtain a stable locking force regardless of the presence or absence of the locking portion P2 of the hanging metal fitting P.

  The clip body 30 is configured so that the reflector 20 can be mounted in the same manner as the portion without the hanging bracket P even when the locking portion 32 rotated to the top of the bent piece 11 interferes with the holding claw portion P3 of the hanging bracket P. (See FIGS. 8 and 9).

  Moreover, when the latching | locking part 32 is rotated on the latching | locking part P2, the holding nail | claw part P3 may become obstructed and it may become unable to rotate (refer FIG. 8). Therefore, a slit 31B is formed on the head 31A of the rotating bolt 31 so that the engagement / disengagement state of the locking portion 32 can be confirmed at a glance (see FIG. 5). The slit 31B is formed on the head 31A of the rotating bolt 31 so as to indicate the direction of the clip body 30, and the direction of the slit 31B is set to the direction of the engaging portion 32 of the clip body 30 to which the rotating bolt 31 is fixed. By matching, the direction of the locking portion 32 can be confirmed via the rotating bolt 31. Accordingly, when the rotating bolt 31 is rotated at the position of the hanging bracket P, if the locking portion 32 cannot be rotated to the position indicating the locked state, it is turned in the opposite direction while checking the direction of the slot 31B. Thus, it can be rotated to the locked position.

  On the other hand, the clip body 30 can be rotated in any direction on the bent piece 11 to which the hanging bracket P is not locked. Further, when the hanging bracket P is nearby, the holding claw P3 of the locking portion P2 may hinder rotation (see FIG. 9). Also in this case, since the locking portion 32 rotates only in one direction, the clip body 30 is operated while confirming the direction of the slit 31B.

  Furthermore, the display unit 21 on which a pattern, characters, designs, etc. indicating the locking state of the locking portion 32 of the clip body 30 are provided at a position surrounding the head 31A of the rotating bolt 31 on the lower surface of the reflecting plate 20 is provided. Thus, the confirmation of the locked state by the locking portion 32 can also be visually confirmed (see FIG. 5). In the illustrated example, when the slot 31B is directed in the direction of the bent piece 11, the lock key 21A indicating the locked state of the locking portion 32 is displayed, and when the slot 31B is directed in the longitudinal direction of the storage body 10. An unlock key 21B indicating the release state of the locking portion 32 is displayed.

  In the reflector 20 used in the present invention, power is supplied to the socket 50 for the straight tube lamp R located at both longitudinal ends of the reflector 20 and the socket 50 and the socket 50 for the straight tube lamp R adjacent thereto. A connector 60 to be supplied and a mount base 70 to which the socket 50 and the connector 60 are attached are attached (see FIG. 10). The socket base 71 of the mount base 70 is used as the support plate 42 of the height adjuster 40.

  The connector 60 is a member that supplies power to the socket 50 and the adjacent continuous socket 50, and is continuously provided along the inside of the lighting case 10. The mount base 70 is a member on which the socket 50 and the connector 60 are mounted, and includes a socket base 71 and a connector base 72 (see FIG. 10). In the illustrated example, a belt-like metal plate is bent into a substantially U-shaped side surface. Then, the socket base 71 is disposed on the reflecting plate 20 side, and the socket 50 is attached to the socket base 71 (see FIG. 1). At this time, the clip body 30 is provided with the socket base 71 on the upper surface of the reflecting plate 21 as the support plate 42, and the clip body 30 is disposed on the socket base 71 (see FIG. 10). Further, a connector base 72 is arranged on the writing case 10 side, and the connector 60 is detachably mounted.

  In addition, the mount base 70 is configured to connect not only a straight tube type fluorescent lamp but also a straight tube type LED lamp as a straight tube type lamp R by mounting members such as a socket 50 and a connector 60 up and down with a gap therebetween. It is also possible to do. That is, there are types that use an LED driver and types that do not use an LED driver, depending on the type of straight tube LED lamp. In addition, even in the same type, there are a double-sided feeding method and a one-sided feeding method. Regardless of which type or power feeding type straight tube LED lamp is selected, it can be easily connected by using the mount base 70 constituted by the socket base 71 and the connector base 72.

  The lighting device of the present invention has been described as being effective mainly when connecting a plurality of straight tube lamps, but it can also be used when a straight tube lamp is used alone, It can also be used for lighting fixtures of the type that are suspended by a hanging bracket, other devices, and the like. Further, the shape and dimensions of the lighting case 10, the reflector 20, the clip body 30, the height adjuster 40, and the like of the present invention, the structure of the hanging metal fitting P, and the like are not limited to the illustrated examples, and the gist of the present invention.
