Description

  The present invention relates to a lighting fixture in which a plurality of fixture main bodies are connected to each other and a light distribution control member such as a louver is provided.

In a conventional lighting fixture of this type (see, for example, Patent Document 1), a louver is disposed on the front surface of each of a pair of fixture main bodies to be coupled to each other, and a lamp is arranged between the fixture main body and the louver. The pair of louvers are respectively attached to the pair of instrument bodies by attachment members.

  However, when a pair of instrument main bodies are connected to each other, there is a problem in that the louvers do not line up continuously and a step is generated between the louvers, which may deteriorate the appearance.

  Therefore, in the first conventional example, as shown in FIG. 5 (a), each louver 50 is provided with a frame 50a, the frame 50a is provided with a mounting structure to the instrument body 51, and the inclination of each connected louver 50 is inconspicuous. It is what I did. However, since the frame 50a is also provided at the adjacent end of the louver 50, it is impossible to realize a highly continuous appearance.

  In the second conventional example, as shown in FIG. 5 (b), a seamless connection is realized by using a louver 53 having an attachment plate 52 at one end. There is a problem that it is necessary to divide the structure for the left side, the left side, and the single side, and the cost is increased and the number management at the time of manufacturing and construction is complicated.

  In the third conventional example, as shown in FIG. 5C, a louver 54 that can be attached to both a single attachment and a connection attachment is directly abutted and connected, but the inclination of the louver 54 in the width direction is corrected. Since there is no mechanism and a step is generated between adjacent ends of the louvers, the fixture width is limited to only a very narrow lighting fixture.

  As a result, there is no unique structure that appears on the appearance of the frame 50a or the like at the adjacent end of the louver 50, the louver has no directionality, and can be used either as a single unit or connected. It was desired to meet the challenge of being easy and reliable.

  Therefore, the objective of this invention is providing the lighting fixture which can satisfy | fill the said request simultaneously and can make light distribution control members, such as a louver, continue without a level | step difference.

  In the lighting fixture of the present invention, each of the pair of fixture main bodies has a connection end. A pair of light distribution control members are disposed on the front surfaces of the pair of instrument bodies. A lamp is disposed between the pair of appliance main bodies and the pair of light distribution control members. The elastic mounting member detachably holds the pair of light distribution control members on the pair of instrument main bodies in a state of pulling the pair of light distribution control members to the pair of instrument main bodies. The connecting member has an abutting portion where adjacent ends of the pair of light distribution control members abut against each other by the pulling force of the elastic mounting member, and connects the connecting ends of the pair of instrument main bodies.

  The said structure WHEREIN: The said connection member makes the part visible from the clearance gap between the said adjacent edge parts of the said light distribution control member the color of the same color system as the said light distribution control member.

  According to the lighting fixture of the present invention, the adjacent end portions of the light distribution control member can be continued without a step by the connecting member. For this reason, it is possible to easily realize a continuous connection of lighting fixtures even with a light distribution control member that does not have a unique structure that appears on the appearance of a frame or the like at an adjacent end of the light distribution control member. In addition, since the light distribution control member has no directionality and can be used for both a single unit and a connection, it is possible to make the member common and reduce the cost. Further, even with a light distribution control member having a wide instrument width, the inclination can be easily and reliably corrected. Further, since the position of the light distribution control member is regulated by the elasticity of the elastic mounting member only by the operation of attaching the light distribution control member, the subsequent adjustment work is unnecessary and the workability is good.

  Since the connecting member and the light distribution control member have the same color, the appearance does not deteriorate.

  The lighting fixture of the 1st Embodiment of this invention is shown in FIG. 1 and FIG. The connecting ends 1 a and 2 a of the pair of instrument bodies 1 and 2 for a straight tube fluorescent lamp are connected to each other by a connecting member 7. One instrument body 1 has a connecting end 1 a having no end wall at one end and a terminal end 1 b having an end wall 3 at the other end. The other instrument body 2 has a connecting end 2a having one end and no end wall, and the other end has an end wall or no end wall. When there is an end wall at the other end of the fixture body 2, the lighting fixture is composed of a pair of fixture bodies 1 and 2. When there is no end wall at the other end of the instrument main body 2, another instrument main body having the same structure as the instrument main body 1 or the same structure as the instrument main body 2 is connected to the other end by the connecting member 7. In the case of the same structure as the instrument main body 2, the instrument main body can be further continuously connected.

  Each of the instrument bodies 1 and 2 is provided with an elastic mounting member 4. The elastic mounting member 4 is formed, for example, in a substantially inverted U-shape with a metal plate, bends overhanging portions 4a projecting outward from each other at both ends, and inclines the ends of the overhanging portions 4a closer to each other. Thus, the drawing portion 4b is provided. By this drawing portion 4b, a pair of louvers 5, 6 described later are detachably held in the drawn state. The elastic mounting members 4 are provided at a plurality of locations in the longitudinal direction of the instrument bodies 1 and 2, but are disposed at a position within a predetermined distance D from both ends of the instrument bodies 1 and 2.

  Each of the instrument bodies 1 and 2 further has a lamp socket (not shown), to which a lamp (not shown) is attached. The lamp is disposed between the pair of instrument bodies 1 and 2 and the pair of louvers 5 and 6, but depending on the length, the lamp is separately disposed on each of the pair of instrument bodies 1 and 2. In some cases, the lamp is arranged so as to straddle the pair of instrument bodies 1 and 2.

  The pair of louvers 5 and 6 that are light distribution control members are disposed on the front surfaces of the pair of instrument bodies 1 and 2. Each of the louvers 5 and 6 includes three vertical louver pieces 10 and 11 and a large number of horizontal louver pieces 12 that bridge the vertical louver pieces 10 and 11. As shown in FIGS. 2A and 2B, the central vertical louver piece 10 has a V-shaped cross section, and the vertical louver pieces 11 on both sides have their lower ends folded outward to form a side frame. The louvers 5 and 6 are attached by opening the pulling portions 4b at both ends of the elastic attachment member 4 and inserting the vertical louver pieces 10 therein. Thereby, the vertical louver piece 10 is pulled toward the instrument main bodies 1 and 2 by the clamping force of the pulling portion 4b.

  As described above, the connecting member 7 connects the connecting ends 1a and 2a of the instrument bodies 1 and 2 to each other, but the metal plate is substantially inverted U-shaped along the inner surface of the instrument bodies 1 and 2. And a pair of abutting pieces 8 that abut against the upper surface of the vertical louver piece 11 at both ends. In this case, as shown in FIGS. 2A and 2B, the elastic attachment member 4 uses the elasticity of the louvers 5 and 6 that are light distribution control members, so that the connecting member 7 contacts the louvers 5 and 6. The louvers 5 and 6 are drawn closer to the instrument main bodies 1 and 2 than the contact position P1. In other words, the tool body has a drawing position P2 in which the louvers 5 and 6 are pulled closer to the tool bodies 1 and 2 by the elastic mounting member 4 than the contact position P1 at which the louvers 5 and 6 contact the connecting member 7. 1 and 2 are set. This dimensional difference d is absorbed by the elasticity of the louvers 5 and 6 by disposing the elastic mounting member 4 inward by a predetermined distance D from the ends of the instrument bodies 1 and 2. Thereby, the vertical louver piece 11 can be elastically contacted with the contact piece 8 by the pulling force of the elastic mounting member 4, and the adjacent ends of the louvers 5 and 6 can be reliably supported without any step.

  The connecting member 7 has the same color as that of the louvers 5 and 6 so that the portion seen from the gap between adjacent ends of the louvers 5 and 6 looks the same as the louvers 5 and 6.

  According to the present embodiment, as shown in FIG. 1, the connecting member 7 corrects the deviation of each instrument body 1, 2 when connecting the instrument bodies 1, 2. In addition, since the elastic mounting member 4 is arranged at an appropriate distance D from both ends of the instrument bodies 1 and 2, the louvers 5 and 6 are bent in the instrument bodies 1 and 2 due to the elasticity of the vertical louver piece 10. The louvers 5 and 6 can be attached by absorbing the step d.

  Further, by attaching the louvers 5 and 6 to the elastic attachment member 4, the louvers 5 and 6 are pulled up to the inside of the instrument main bodies 1 and 2, but at the same time, in the vicinity of the connection ends 1a and 2a, the connection member is caused by the dimensional difference d shown in FIG. 7, the position of the louver 5 at the connecting ends 1a, 2a is restricted. At this time, since the other louver 6 is similarly regulated, the inclination in the width direction of each of the louvers 5 and 6 is equally corrected, and a continuous appearance can be realized only by the mounting operation. Further, in these structures, since it is not necessary to give the louvers 5 and 6 a unique function as in the prior art, a louver having the same shape can be attached to any instrument body. Further, since the connecting member 7 is coated in the same color system as the louvers 5 and 6, a good appearance is maintained even when viewed from the gap between the louvers 5 and 6.

  A second embodiment of the present invention will be described with reference to FIGS. That is, in the first embodiment, there is no vertical louver piece 11 on both sides of the louvers 5, 6, and the connecting member 7 is also substantially fitted to the upper side of the central vertical louver piece 10 having a V shape. It is formed in a V shape, and both ends thereof are extended outward to form attachment pieces 7a, and the instrument bodies 1 and 2 are connected by the attachment pieces 7a.

  In this embodiment, since the feed wiring between the instrument bodies 1 and 2 passes through the internal space of the connecting member 7 and the feed wiring is hidden by the connecting member 7, the appearance is good. Others are the same as in the first embodiment.

  In each embodiment, the case where two instrument bodies are connected is shown, but three or more connections are possible. In addition to the louver, the light distribution control member includes a cover. The elastic attachment member 4 may be a V-shaped spring, or may be attached to the light distribution control member side to hold the instrument body.
