Abstract

PURPOSE:To reduce a local lumination unevenness by disposing each straight tube type fluorescent lamp equally in parallel or in vertical to each line connecting each middle point of each side of each square module block on a ceiling face with each middle point of the both sides adjacent to each side, with the middle point of said each line as the center. CONSTITUTION:The line connecting each middle point A, B, C, D of each side of each square module block 2 with each middle point of the both sides adjacent to each side generates a square of an area 1/2 the original square which is inclined at 45 deg.. When each line is drawn for each module of the ceiling having an aggregate of a plurality of square modules, a grating network having meshes of an area 1/2 each module area at regular intervals is obtained. The center of a straight tube type fluorescent lighting equipment 1 is positioned in the middle point P, Q, R, S of each mesh, and the lamp 6 of each lighting equipment is disposed equally in parallel or in vertical to the line on which the center of the lighting equipment is positioned. Hence, the center of each module 2 and the border part 5 of four modules can be placed in an uniform luminous condition, resulting in a reduction in local lumination unevenness.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ceiling equipment device in which lighting fixtures and the like are arranged indoors of a building such as an office building.

[Conventional technology]

On the general floors of this divinely large office building, in order to increase the flexibility of partitions, a collection of unit compartments called "modules" equipped with the minimum necessary functions for indoor equipment such as lighting and air conditioning are used to increase the flexibility of room partitions. The idea of configuring this module has become common.Recently, the ceiling equipment installed in this module has been studied, for example, in Japanese Patent Application Laid-Open No. 62-7833.
An example of a broken ceiling plan view is shown in FIG. 3 disclosed in Publication No. 8. An example of this disclosure is
As lighting equipment, four lighting equipment 1 consisting of straight tube fluorescent lamps (lamps) 6 are arranged in the center of each square module and parallel to each side of the module section 2 to form an annular square. A sensor, a broadcast speaker, etc. are arranged at each corner 3. In such an arrangement,
It is disclosed that since the lighting fixtures l are arranged in all directions, a good lighting effect can be obtained without creating any shadows.

(Problem to be solved by the invention) However, when each lighting fixture is arranged in the above arrangement, if the room is partitioned by multiple modules,
There is a bias in the placement distribution of each 111 bright fixtures, and the illuminated surface has high illuminance on the inside 4 of the annular square with the lighting fixtures as four sides. The illumination of the boundary part 5 is likely to cause uneven illumination, such as locally low illuminance, and the spacing of the equipment lines, which are treated as an extension of the previous system ceiling system in which the equipment lines are configured through the main frame, is difficult. There were problems in that it was uneven and unsightly, and the structure was complicated and expensive, as lighting equipment with a special structure was required to avoid stiffness.

As described above, this invention not only provides a good lighting effect without causing local shadows for each module, but also provides a distribution distribution of each lighting fixture even when partitioned into multiple modules. One of our objectives is to provide a ceiling equipment device at a low cost that has less unevenness in local illuminance and is less uneven in illuminance.

(Means for solving the problem) Therefore, in the ceiling equipment device of the present invention,
The straight tube fluorescent lighting fixture is centered at the midpoint of each line segment that gently connects the midpoint of each side of the square valley module section on the ceiling and the midpoints of both adjacent sides of each side. The above objective is achieved by arranging the straight tube fluorescent lamps in seven rows or vertically in line with each line segment.

[Effect]

With the above configuration, the line segment connecting each midpoint of each side of each square module section and the midpoint of both adjacent sides of each side is
In the end, we will draw a square that is 1/2 the area of the original square and tilted 45 degrees. When each of the line segments is drawn for each module of a ceiling having an aggregate of a plurality of square modules, a lattice network having an area of 1/2 of the area of each module and equally spaced grids is created. The center of the straight tube fluorescent lighting fixture is located at the midpoint of j, and the lamp of each lighting fixture is parallel to or overlaps the line segment where the center of the lighting fixture is located. By directly arranging the modules, the center of each module and the portion 5 that forms the boundary between the four modules are provided with uniform illumination conditions, and local unevenness in illuminance can be reduced.

〔Example〕

The present invention will be explained below based on examples. FIG. 1 is a cutaway ceiling plan view showing an embodiment of the ceiling equipment according to the present invention, and the same (or equivalent) components as in FIG. 3 of the conventional example are designated by the same reference numerals.

(Structure) Squares divided by dashed lines indicate each module section 2. The midpoints of each side of the module section 2 are tNA, B, C, and D, and the midpoint of line segment AB is P, line segment B
The midpoint of C is Q, the midpoint of the line segment plane is R1, the midpoint of line segment DA is S
Then, there are four straight tube fluorescent lighting fixtures 1, each centered at P and Q.

R and S, and each lamp 6 is arranged parallel to each line segment.

Therefore, as is clear from the figure, the bowl lighting fixtures 1 are evenly arranged as a module assembly, and local unevenness in illumination unlike the conventional example does not occur.

In addition, in order to facilitate the installation of such lighting equipment, the ceiling should be lined with one line passing through the main frame in the direction of lines 7 and -10,000, and lines AB and DC should be crossed. 4. A typical system ceiling system with a frame passing structure and an equal spacing between equipment lines.
Since it can be considered as an extension of the 5° tilted configuration, the lighting fixture itself can also be a conventional system ceiling type straight tube fluorescent lighting fixture.

In addition, 7 is an equipment plate for the main frame, and 8 is an equipment plate for the cross frame. You can get enough margin by comparing.

(Other Embodiments) FIG. 2 shows a second embodiment of the ceiling equipment device, which is a modification of the actual Mi example shown in FIG. 1. As is clear from the comparison between the two figures, in the first embodiment, each lamp 6 is connected to each line segment 7;
, εD, and DA are arranged parallel to each other at a fidget rate, whereas this second example h6 is arranged perpendicularly to each of the above-mentioned line segments, and the first Of course, the same effect as in the actual example can be obtained.

〔Effect of the invention〕

As explained below, according to the present invention, four straight tube fluorescent lamps are arranged in each module section;
1t, which can reduce local illumination unevenness, and can also be used as a ceiling configuration or as an extension of the general system Tenno 1 method.
It has the advantage that it can be provided at low cost.
