JPH0343907A - Disposition and holding structure for line type lighting apparatus on ceiling - Google Patents

Abstract

PURPOSE:To be able to flexibly meet the requirement for changing the arrangement of line type lighting apparatuses hung from a ceiling by making the direction of multiple line type lighting apparatuses changed able as required. CONSTITUTION:A central part of each line type lighting apparatus 2 is hung- supported via a revolving support member 3 from a ceiling so that each lighting apparatus 2 may be turned to any direction about the revolving support member 3. The line type lighting apparatuses neighboring each other in both lateral and longitudinal directions are spaced so that they do not interfere with each other when they are revolved for changing their directions. The lighting apparatuses near to partition walls 5 and concrete walls are also disposed with spacings for avoiding the interference. This arrangement enables the arrangement of the line type lighting apparatuses 2 on the ceiling to be changed by revolving each lighting apparatus 2 about the revolving support member 3 in any required direction.

Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a method for arranging a large number of line-type lighting fixtures on the ceiling of an office or retail store, and a holding structure for the lighting fixtures.
In particular, the orientation of each line type lighting fixture on the ceiling can be easily changed.

"Prior Art" Conventionally, no particular way of thinking has been established regarding the arrangement of lighting fixtures on wide ceilings in offices, retail stores, and the like.

Additionally, lighting fixtures arranged on the ceiling usually have to be installed before the office fixtures and fittings and store product plans have been decided. In particular, when the occupant is a tenant, the layout plan cannot be predicted at all, and therefore the lighting fixtures are arranged based on subjective judgment on the part of the builder.

``Problem to be solved by the invention'' The work of arranging a large number of lighting fixtures on a wide ceiling is carried out before the equipment layout plan for offices and product plans for retail stores, etc., have yet to be determined. Problems with lighting effects arise when determining product placement. In other words, lighting effects in offices, stores, etc. are an important means of proactively appealing to customers about work efficiency or product value, and cannot be ignored, and the lighting has to be changed many times. Particularly when the lighting fixture is a line type, the lighting effect tends to be directional, which tends to cause problems.

The present invention aims to provide a method for arranging a line-type lighting device and a holding structure for solving this problem in a simple manner.

``Means for Solving the Problems'' The present invention is designed to flexibly respond to changes in the arrangement of line-type lighting fixtures suspended from the ceiling due to changes in partition walls or changes in the arrangement of desks, etc. This paper describes a ceiling arrangement method and a holding structure for a line-type lighting fixture.

To make it possible to change the direction of line-type lighting equipment,
The lighting fixture can be held on the ceiling by providing an engagement hole in the center of the top surface of the line-type lighting fixture and allowing the engagement hole on the lighting fixture side to pivot freely and engage the pivot support member arranged on the ceiling side. It has become. In addition, many line-type lighting fixtures,
They are arranged at intervals so that they do not come into contact with adjacent ones when changing direction, and those at corners are arranged at intervals so that they do not come into contact with the partition wall.

``Effect'' By changing the position of partition walls or changing the arrangement of desks, etc.
When it is desired to change the arrangement direction of the line-type lighting fixtures on the ceiling surface, each line-type lighting fixture can be swiveled around the swing support member to face in an appropriate direction. Therefore, the direction of the line type lighting equipment can be easily changed, and the lighting effect can always be adjusted to be good even when the arrangement is changed in an office or store.

"Example" Embodiments of the present invention will be described with reference to FIGS. 1 to 4.

A large number of line-type lighting fixtures 2 are arranged on a ceiling surface l at equal intervals in both the vertical and horizontal directions, as shown in FIG.

The center portion of each line type lighting fixture 2 is suspended from the ceiling via a swing support member 3, and each line type lighting fixture 2 can be rotated in any direction around the swing support member 3. . The swing support member 3 is fixed to the ceiling base 1b with screws or the like, and air outlets 4 are provided at appropriate intervals on the ceiling surface. Note that line-type lighting equipment uses rod-shaped fluorescent lamps.

The line-type lighting fixtures 2 that are adjacent to each other vertically and horizontally are spaced apart so that they do not come into contact with each other even when they turn to change their directions. In addition, the line type lighting fixtures 2 located close to the partition wall 5 or the concrete wall are arranged at such intervals that they do not come into contact with the partition wall 5 etc. when turning to change direction. If the distance between adjacent line-type lighting fixtures 2 and the distance between the partition walls is minimized, an arrangement with good appearance can be obtained.

The embodiment shown in FIG. 2 is applied to the ceiling of a room partitioned by a partition wall 5 to accommodate a change in purpose, and the line-type lighting fixtures 2 are arranged in a mixed manner both vertically and horizontally. Furthermore, a rack 6 is provided near the wall to improve usability.

Each line type lighting fixture 2 is provided with an engagement hole 7 in the center of the base side that contacts the ceiling surface l, and the engagement hole 7 is engaged with the swing support member 3 fixed to the ceiling. A line type lighting fixture 2 is rotatably held on a ceiling surface. Note that four locking pieces 3a are protruded from the lower end of the swing support member 3, and a groove 7a corresponding to the locking pieces 3a is also provided in the engagement hole 7 of the line type lighting fixture 2, so that the locking pieces 3a are It is adapted to be locked around the engagement hole 7.

Further, the electric wire 8 that supplies power to each line type lighting fixture 2 is connected to a power source through a through hole in the ceiling finishing material 1a and the ceiling base 1b.

With the above configuration, when changing the longitudinal direction of each line-type lighting fixture 2, each line-type lighting fixture 2 is rotated around the swing support member 3, and for example, the line-type lighting fixture 2 shown in the solid line state in FIG. The lighting fixture 2 can be changed to the state shown by the dashed-dotted line in FIG. Therefore, even if the arrangement of fixtures, desks, etc. in an office or store is changed, the orientation of the line type lighting fixture 2 can be easily changed to obtain a good lighting effect.

``Effects of the Invention'' According to the present invention, the installation (=I direction) of line-type lighting equipment can be changed freely in a simple manner, and when redecorating an office or retail store, etc., the installation of the lighting equipment can be done without removing it. There is no need for labor, and there is no worry about equipment damage or the need for specialized workers.

Furthermore, if the spacing between line-type lighting fixtures is kept to a minimum, there is an aesthetic effect in that both vertical and horizontal arrangements look good.
