Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling-embedded luminaire having a baffle on the lower surface, and more particularly to a baffle in which a plurality of luminaires are connected in the longitudinal direction. Lighting equipment.

2. Description of the Related Art A conventional first example in which ceiling-embedded luminaires are continuously arranged in the longitudinal direction will be described with reference to FIG. In this conventional example, two lighting fixtures 4 each having a plurality of baffle blades 3 arranged at equal intervals are connected to each other by a connecting fitting 5 on a lower surface of a main body 2 of an opening of a lower surface which holds a straight tube fluorescent lamp 1. is there. In this case, the frame portion 7 projecting outward of the end plate 6 of the instrument body 2 is arranged in contact with or close to it.

Therefore, there is a problem that a shadow is generated by the frame portion 7 of the end plate 6 at the abutting portion of the two lighting fixtures 4 and the appearance is poor. In addition, lighting equipment 4 completed for each one
Since two units are used, there is a problem in that there is no sense of unity in appearance.

In order to solve such a problem, a structure as shown in FIG. 10 is adopted. That is, each lighting fixture 4
The end plate 6 of the butting portion is eliminated, and the connecting portion 8 to which the instrument main body 2 is directly connected is provided. This gives a sense of unity when the two units are connected.

Problems to be Solved by the Invention In what is shown in FIG. 10, the baffle vane 3 cannot be attached to the connecting portion 8 where the two instrument bodies 4 are butted, and in FIG. The baffle blade 3a and the baffle blade 3b, which are close to each other, are greatly opened. Therefore, the mounting pitch of the baffle blades 3 in this portion is greatly changed from that in the other portions, and the appearance is impaired.

In addition, the fact that the mounting pitch of the baffle blades 3 at the connecting portion 8 is large means that the function of the baffle blades 3 itself that prevents glare in the longitudinal direction of the lamp from exceeding a certain angle is not partially satisfied. The fact that glare occurs even in a part means that the function as an instrument is unsatisfactory.

Means for Solving the Problems A V-shaped reflector is attached to an instrument body having a bottom opening for holding a straight tube fluorescent lamp, and a plurality of slit grooves orthogonal to the longitudinal direction are formed in the V-shaped reflector. In a lighting fixture having a baffle blade attached to a slit groove, a connecting portion for directly connecting the ends of the main body of the fixture and the V-shaped reflector along the longitudinal direction is formed, and the end of the connecting portion is formed. A notch was formed in which the baffle blade was inserted.

Action Even if a plurality of lighting fixtures are connected and arranged, the baffle blades are attached to those connecting parts, so there is no change in the mounting pitch of the baffle blades overall, which results in an aesthetic appearance. Can be improved, and the baffle blades can be evenly arranged, so that the function of the baffle blade itself, which prevents glare in the longitudinal direction of the lamp from exceeding a certain angle, can be sufficiently achieved. It is configured as follows.

Embodiment A first embodiment of the present invention will be described with reference to FIGS. 1 to 7. In this embodiment, as shown in FIGS. 9 and 10, two lighting fixtures 4 are connected in series.
The same parts as those described with reference to FIG. First, at the end of the instrument body 2 with the lower surface opening,
A socket base 9 is attached, and a socket 10 for holding the straight tube fluorescent lamp 1 is attached to the socket base 9.
Further, the reflection plate 11 opening downward is attached by a reflection plate attachment screw (not shown). Further, a reflection plate attachment frame 12 is fixed to the socket base 9, and a V-shaped reflection plate 13 is attached to these reflection plate attachment frames 12 with attachment screws 14. Slit grooves 15 are attached to the V-shaped reflection plate 13 at a constant pitch.
Baffle blades 3 orthogonal to the longitudinal direction of the V-shaped reflector 13 are attached. These baffle blades 3 have two projecting pieces 16 inclined outward at the upper edge thereof, and these projecting pieces 16 are engaged with the inner surface of the V-shaped reflection plate 13 so as not to drop downward. It is what is being prevented.

Thus, the instrument body 2, the reflector 11 and the V-shaped reflector 13 have a connecting portion 8 that is directly connected to each other. A notch 17 having a width corresponding to the thickness of the baffle blade 3 is formed below the edge of one V-shaped reflector 13. Then, on the inner surface of the end portion of the V-shaped reflection plate 13, there is formed a connecting surface which coincides with the inner surface and leaves the slit groove 15.
A connection support plate 19 having 18 is fixed. for that reason,
The other V-shaped reflection plate 13 is fitted into the connection auxiliary plate 19 so that each V-shaped reflection plate 13 is connected. The connecting portion 8 of the V-shaped reflecting plate 13 thus connected has a notch portion 15, and the baffle blade 3 is attached to the notch portion 15. Therefore, the baffle blades 3 are arranged at a constant pitch in a state where the two lighting fixtures 2 are connected.

In such a configuration, the two lighting fixtures 2 are arranged on the ceiling surface. In this case, it goes without saying that the baffle blades 3 are connected to the V-shaped reflector 13 at a predetermined pitch. Since one baffle blade 3 is also attached to the connecting portion 8 of the V-shaped reflector 13, the baffle blades 3 are arranged at a constant pitch over the entire state in which the two lighting fixtures 2 are connected. It will be. Therefore, the appearance is improved and, in particular, the straight tube fluorescent lamp 1
The function of the baffle blade 3 itself, which prevents glare in the longitudinal direction from above a certain angle, can be achieved as a whole.

Next, a second embodiment of the present invention will be described with reference to FIG. In this embodiment, a notch 17 having a thickness half that of the baffle blade 3 is formed in each of the facing portions of the V-shaped reflectors 13 facing each other. The notch 15 is formed so that the baffle blade 3 is located. Further, in that one of the V-shaped reflectors 13 is provided with the connection auxiliary plate 19,
Similar to the above-described embodiment, the connection auxiliary plate 19 is also formed with a notch into which the baffle blade 3 is inserted.

In such a configuration, in the above-described embodiment, the position of the baffle blade 3 attached to the connecting portion 8 is strictly displaced by half the thickness of the baffle blade 3, but According to the embodiment, the baffle blade 3 is located at the center of the connecting portion 8.

In each of the above embodiments, the V-shaped reflector 13 has a cutout portion.
In the embodiment, the V-shaped reflection plate 13 is positioned such that a gap is formed between the opposite ends of the V-shaped reflection plate 13, and the V-shaped reflection plate 13 is arranged. However, the baffle blade 3 may be attached by forming a slit in the connection assisting plate 19.

EFFECTS OF THE INVENTION As described above, the present invention attaches a V-shaped reflector to an instrument body having a lower opening for holding a straight tube fluorescent lamp, and forms a plurality of slit grooves perpendicular to the longitudinal direction on the V-shaped reflector. Then
In a lighting fixture in which baffle blades are attached to these slit grooves, a connecting portion for directly connecting the ends of the main body of the apparatus and the V-shaped reflector along the longitudinal direction is formed. Since the notch for inserting the baffle blade is formed at the end, even if a plurality of lighting fixtures are connected and arranged, the baffle blade is attached to these connecting portions, so the baffle blade is entirely Since there is no change in the mounting pitch of the lamp, it is possible to improve the aesthetic appearance and evenly arrange the baffle blades, so that it is possible to prevent glare in the longitudinal direction of the lamp above a certain angle. This has an effect that the function of the so-called baffle blade itself can be sufficiently achieved.
