Description

[Detailed explanation of the idea] This invention relates to a multi-lamp type lighting fixture.

Conventionally, as shown in FIGS. 1 to 3, a plurality of straight tube lamps 2 are arranged in parallel and attached to a trapezoidal reflector 1, and a V-shaped reflector is positioned between the lamps 2. 3 and a louver 4 fixed to the reflector 3 and perpendicular to the longitudinal direction of the lamp 2 are removably fixed to the reflector 1°, thereby cutting glare when projecting light. exists.

However, in such a device, the ceiling surface of the reflector 1 is wide and flat, so the ceiling surface is easily deformed in the vertical direction, and this deformation causes the V-shaped reflector 3 and the louvers 4 to be attached to the mounting surface of the reflector 1. When installing, a positional shift occurs between the mounting surfaces of the reflector 1 and the V-shaped reflector 3, making it impossible to install them in the correct position.

In particular, in the case shown in FIG.
However, in this mounting form, the deformation of the reflector plate 1 is even greater.

This idea was developed in view of these points, and is designed to increase the rigidity of the reflector to prevent deformation, thereby uniformly cutting glare and enhancing the appearance.

A reflecting plate is provided, which is integrally formed by bending a flat surface covering the upper parts of at least four straight tube lamps installed in parallel and a V-shaped reflecting surface located between the lamps, and A separate V-shaped reflector is attached between at least two of the lamps.

Therefore, the rigidity of the reflector is increased so that when other V-shaped reflectors or louvers located between the lamps are attached to this reflector, they can be attached in the specified normal state, thereby uniformly cutting glare. The appearance is also improved, and by forming a V-shaped reflective surface on the reflector plate, the number of other V-shaped reflector plates placed between the lamps can be reduced, making production easier. It is designed to be transparent.

A first embodiment of this invention will be explained based on FIGS. 4 to 8.

Reference numeral 7 denotes a reflector plate that is directly attached to the ceiling, and this reflector plate 7 has a cross-sectional shape in which a V-shaped reflective surface 8 that expands upward is formed in the center and bent pieces 9 are formed on both side edges. ing.

Two straight tube lamps 10 are held on each side of the reflecting surface 8 on the ceiling surface of the reflecting plate 7.

Further, adjacent lamps 10 are provided on both sides of the reflective surface 8.
Another V-shaped reflecting plate 11 located between the two is fixed.

A plurality of louvers 12 are connected to these reflecting plates 11 in a direction perpendicular to the longitudinal direction of the lamp 10 .

Further, end plates 13 are fixed to both ends of the reflector plate 7 to close the opening surfaces thereof.

These end plates 13 have cut and raised pieces 14 that are joined to the back surface of the reflective surface 8 .

Thus, the cable rack 15, which is a support member having a U-shaped cross section, is fixed with both ends thereof in contact with the back surface of the reflective surface 8.

A through hole 16 is formed on the back surface of the reflective surface 8, through which an electric wire (not shown) inserted into the cable rack 15 is passed.

In such a configuration, a ■-shaped reflecting surface 8 is formed on the ceiling surface of the reflecting plate 7, and since the inclination angle of this reflecting surface 8 is determined by the cable rack 15, the rigidity of the reflecting plate 7 is increased. It becomes difficult to deform.

As a result, the other V-shaped reflectors 11 and louvers 12 can be attached to the mounting surface of the reflector 7 without any displacement, and glare can be uniformly cut in all parts, improving the appearance.

Further, although a V-shaped reflecting plate 11 is required between the lamps 10, by forming a ■-shaped reflecting surface 8 on the reflecting plate 7,
It is also possible to reduce the number of letter-shaped reflecting plates 11, and manufacturing is easy.

The cut and raised piece 14 bonded to the back surface of the reflective surface 8 can also prevent the angle of the reflective surface 8 from being misaligned.

In addition, as shown in FIGS. 9 and 10, a connecting plate 17 extending in the left-right direction is provided on the upper surface of the cable rack 15,
By fixing these connecting plates 17 together with the end plates 13 to the upper surface of the reflecting plate 7, it is possible to further strengthen the rigidity of the reflecting plate 7.

Next, a second embodiment of this invention is shown in FIGS. 11 and 12.
This will be explained based on the diagram.

The same parts as in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, a reflecting plate 7 is suspended by hanging bolts 5 while its peripheral edge is joined to a ceiling 6.

That is, two plates 18, which are supporting members orthogonal to the reflecting surface 8, are fixed to the upper surface of the reflecting plate 7.

In the center of these plates 18, two arc-shaped slit holes 19, which are approximately semicircular, are formed on the same circumference.

Therefore, by poking between the two slit holes 19 with a screwdriver or the like, a circular hole is formed, and the hanging bolt 5 is fixed to this circular hole with the nut 20.

The plate 18 holding the hanging bolt 5 can further increase the strength of the reflecting plate 7.

As described above, this invention includes a reflecting plate formed by bending a flat surface covering the upper part of a plurality of straight tube lamps installed in parallel and a ■-shaped reflecting surface located between the lamps, and By attaching another V-shaped reflector plate between the lamps located on a flat surface, the rigidity of the reflector plate can be increased and deformation can be prevented. Since the shape of the reflector and louver are attached, the installation can be done without any misalignment on the mounting surface.Therefore, it is possible to cut glare uniformly from each part and improve the appearance. This has the advantage that manufacturing can be facilitated by reducing the number of other V-shaped reflective plates used for partitioning.
