Description

  The present invention relates to a luminaire, and more particularly to a luminaire that can be installed at the fitting pitch of a conventional luminaire as a retrofit application.

  In the field of lighting, recently, luminaires using LEDs have become widespread, but in the past, lighting using incandescent lamps and discharge lamps was mainstream. For example, in tunnel lighting, lighting using a low pressure sodium lamp has been widely used because of its high efficiency and long life.

  At present, as lighting fixtures using low-pressure sodium lamps become obsolete, LED lighting fixtures are increasingly being replaced. In particular, in tunnel lighting, since it is necessary to carry out a lighting fixture replacement work while traffic regulation is performed, it is preferable that the number of works such as newly embedding anchor bolts for lighting fixture installation be small. That is, the mounting pitch of the new luminaire needs to be the same as the mounting pitch of the conventional luminaire.

  In luminaires using traditional low-pressure sodium lamps, lamps with 35 W, 55 W and 90 W lamps were mainly used. In the current LED lighting apparatus, the efficiency and irradiation technology of the LED elements are improved, so even a lighting apparatus equivalent to a 90 W low-pressure sodium lamp can be made smaller than conventional products. Therefore, considering the manufacturing cost of the LED lighting apparatus, it is more advantageous to unify the housing of the lighting apparatus that houses the light source module into one type.

  However, in the case of a luminaire using a conventional low-pressure sodium lamp, the housing is different for each lamp output, and the mounting pitch for mounting to a structure such as a tunnel has two types even if it is limited to many used types. In particular, in the case of a luminaire in which the anchor bolt is directly driven into the inner wall of the tunnel and the bolt is attached to the mounting hole of the luminaire, the mounting pitch of the new luminaire needs to be the same as the mounting pitch of the old luminaire. Therefore, even if the housing of the LED lighting apparatus is unified into one type, it is necessary to correspond to two types of mounting pitches.

  In examining the prior art, there have been the following methods as techniques for making the instruments correspond to a plurality of mounting pitches of the structure. First, an adapter (pedestal) is provided between the structure and the instrument body, a plurality of mounting holes and slots are provided in this adapter, and an adjustment member is further combined to match the mounting pitch of the structure. There is a method of fixing (see Patent Document 1). Further, there is a method of preparing a plurality of attachment members in accordance with a plurality of types of structure attachment pitches (see Patent Document 2).

  If it is attempted to adopt the technology of Patent Document 1 for lighting equipment such as tunnel lighting, the structure of the adapter becomes quite complicated. Although the manufacturing cost of the adapter is low compared to the lighting equipment, the cost of the adapter can not be ignored because many are installed in one tunnel. Moreover, when it is going to adopt the technique of patent document 2 to lighting fixtures, such as tunnel lighting, it is necessary to prepare many mounting brackets, and since it is necessary to bring back other than one type of bracket used in the field, it is useless. There are many.

In order to solve the above-mentioned subject, the lighting fixture of the present invention has a pair of attachment members for attaching the above-mentioned case to the above- mentioned structure outside the left-right direction of a case, and a pair of above-mentioned attachment members has a mounting portion and a structure attachment section, the structure mounting portion, in the left-right direction outer side and the vertical direction outside of the position of the housing mounting portion and the in front view from the housing, in the direction of visible openings in the front view It is a lighting fixture which has a structure attachment hole and can replace | exchange the housing attachment position of said pair of attachment members mutually.

  The lighting fixture described in claim 2 of the present invention has a pair of mounting members for mounting the housing to the structure in the lateral direction of the housing, and the pair of mounting members includes the housing mounting portion and the housing mounting portion. It has a structure attachment portion, and the housing attachment portion is attached to a lateral side surface of the housing, and the structure attachment portion is parallel to the rear surface of the housing from the housing attachment portion and is laterally outside. And a structure mounting hole at a position provided on the outer side in the vertical direction of the housing in a front view, and the housing mounting positions of the pair of mounting members can be interchanged with each other.

  FIG. 1 is a view showing an installed state of the tunnel lighting device 1. As shown in FIG. 1, the tunnel lighting fixtures 1 are installed at predetermined intervals along the road 11 on the wall surface or ceiling surface (the ceiling surface in the present embodiment) of the tunnel 10 where the road 11 extends. In the road 11, the road surface 12 is divided by two roadway outside lines 12A and 12B extending in parallel. In the present embodiment, the tunnel lighting device 1 is a roadway on the far side (the opposite side to the near side) at the position where the lamp direct axis K has entered the road surface 12 by the width L1 from the roadway outside line 12A on the near side (front side). It is installed on the ceiling surface of the tunnel 10 in a posture located on the near side by a width L2 from the outer side line 12B. In the present specification, the direction in which the road 11 extends (the direction in which the vehicle travels) is defined as the longitudinal direction J, and the direction orthogonal to the longitudinal direction J is defined as the transverse direction M. In addition, when the lighting fixture 1 is arrange | positioned only on one side of the tunnel 10 like this example, this lighting fixture 1 has a light distribution which can be illuminated over the cross direction of the road 11 whole.

  An example of the lighting fixture of this invention is shown to FIGS. 2-4. FIG. 2 is a front view, (A) shows a configuration in the case of being assembled corresponding to a long mounting pitch, and (B) shows a case of short length correspondence. FIG. 3 is a view of the same luminaire as viewed from the bottom in FIG. 2, and as in FIG. 2, (A) shows a configuration when assembled corresponding to a long mounting pitch, (B) corresponds to a short length Shows the case. FIG. 4 is a view of the same luminaire as viewed from the left side in FIG.

  As described in FIG. 2, the directions of the top, bottom, left, and right when viewing the lighting apparatus 1 from the front are referred to as “upper”, “lower”, “left”, and “right” in the present specification. The luminaire 1 of this embodiment is installed in a structure such as a tunnel 10 so that the left-right direction coincides with the longitudinal direction J in FIG. Also, as described in FIG. 3, in the present specification, the upper side of the lighting device 1 is referred to as “front” when viewed from below, and the lower side is referred to as “rear”.

  In FIG. 2, reference numeral 2 denotes a housing which is a main body of the lighting fixture 1, and reference numeral 3 denotes an irradiation port for emitting light emitted from a light source (not shown) attached to the inside of the housing 2 to the outside. . Reference numerals 2a to 2d denote an upper surface, a lower surface, a left side surface, and a right side surface of the housing 2, respectively. Further, as shown in FIG. 3, 2f is a front surface of the housing having the irradiation port 3 (see FIG. 2), and 2r is a rear surface of the housing. 4L4R is a pair of left and right mounting members, each mounting member is a housing mounting portion 5 for fixing to the side surface of the housing 2 using a bolt or the like, and the lighting fixture 1 is a structure such as a tunnel 10 It has a structure mounting portion 6 and a structure mounting hole 7 for fixing. In FIG. 4, only the housing 2 and one mounting member 4L are visible, and the other mounting member 4R is not visible because it is behind the mounting member 4L.

  In the present embodiment, the pair of left and right mounting members are shaped so as to be line symmetrical with respect to the vertical line. That is, in FIG. 2, when the attachment surfaces of the case attachment parts 5 of the pair of left and right attachment members 4L 4R are brought into contact with each other except the case 2, the shape becomes symmetrical. In FIG. 2A, the mounting member 4L is mounted on the left of the housing 2 and the mounting member 4R is mounted on the right of the housing 2, and the distance between the left and right structure mounting holes is wide. With this configuration, the lighting fixture can be mounted at a place where a conventional lighting fixture with a relatively long mounting pitch (for example, for a low pressure sodium lamp with a mounting pitch of 400 mm) has been installed. Also, if the mounting member 4L is mounted on the right of the housing 2 and the mounting member 4R is mounted on the left of the housing 2 as shown in FIG. 2B, a conventional lighting fixture with a relatively short mounting pitch (for example, mounting pitch 300 mm) The luminaire can be installed where the low pressure sodium lamp of Thus, the lighting fixture according to the present invention can cope with two types of structure mounting pitches by mutually replacing the housing mounting positions of the pair of mounting members 4L4R.

  Further, the position of the structure attachment hole 7 is provided below the lower end of the housing 2, that is, the lower surface 2 b of the housing 2. For this reason, as shown in FIG. 2 (B), the structure mounting hole 7 can be seen from the front, and it is fitted to the anchor bolt of the structure where the old lighting fixture with a relatively short mounting pitch was installed. The lamp can be attached.

  The shape of the luminaire of this embodiment as viewed from below is as shown in FIG. 3, and the structure attachment portion 6 of the attachment member 4L4R is on the further rear side than the rear surface 2r of the housing 2 Is configured. Therefore, the pair of left and right mounting members 4L4R are configured such that a space is provided between the structure mounting surface of the structure mounting portion 6 and the rear surface 2r of the housing 2 in a state of being fixed to the housing 2. . With such a structure, even when the rear surface 2r of the housing 2 is not flat or when any member is fixed to the rear surface, they do not contact the structure such as the tunnel 10. In addition, installation is facilitated when the lighting fixture is attached with a hexagonal nut or the like to the place where the old lighting fixture with a relatively short mounting pitch was installed. Conversely, when the difference in level between the structure attachment surface of the structure attachment portion 6 and the rear surface 2r of the housing 2 is small and almost no space is provided between the two, the position of the structure attachment hole 7 is set to the housing 2 In addition to the dimensions in which the hexagonal nut and the washer are inserted, it is necessary to secure the interval for moving the tool by providing the lower side 2b sufficiently lower than the lower surface 2b.

  As shown in FIG. 4, when the mounting member according to the present invention is viewed from the side of the housing, the housing mounting portion 5 has a housing mounting hole 5a 5b. The housing mounting hole 5a is a round hole, and the other housing mounting hole 5b is an arc shaped long hole centered on the center point of the housing mounting hole 5a. With such a configuration, when installed in a structure, the attachment angle of the housing 2 can be changed and adjusted after the fixing between the housing 2 and the mounting member 4L4R is slightly loosened. Therefore, when installing the luminaire, it is possible to accurately align the axis K directly under the lamp in FIG. 1 with a desired position. Although one attachment member 4L is illustrated in FIG. 4, the other attachment member 4R has a similar structure.

  As described above, in the present embodiment, the luminaire has a rectangular housing in a front view, but the shape of the housing is not limited to this, and parallel portions are provided at both ends of a circle in square in front view. It may be a housing.

  In the present embodiment, the structure mounting hole of this embodiment is constituted by one long hole per mounting member, but a plurality of round holes may be used. Moreover, you may be comprised by several long holes.
