Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of selecting a lighting device to be installed in a room or the like according to a required illuminance.

[0002]

2. Description of the Related Art A luminaire may be replaced with a new one desired by the owner when the building is constructed or reconstructed. Further, in order to obtain the illuminance desired by the owner, the illuminance of the luminaire may be calculated and the luminaire may be selected. The mounting position of the lighting fixture selected in this way is CAD (Co
It may be shown in the drawing in advance by using a computer aided design) or the like. Such a technique is disclosed in Japanese Patent Application Laid-Open No. 3-103974.

[0003]

By the way, when the luminaire is attached to a predetermined position such as a ceiling based on a drawing of a room or the like, the brightness of the luminaire is not sufficient and the illuminance may be insufficient. is there.

As described above, if the luminaire is selected incorrectly, it is necessary to add or replace the luminaire.
Cost loss occurs.

An object of the present invention is to eliminate the above drawbacks and to provide a method of selecting a lighting fixture that selects the type of lighting fixture that satisfies the required illuminance.

[0006]

In order to achieve the object of the present invention, the data of the types of luminaires and the brightness of these luminaires are held as a database, and the illuminance required for a room is given. , The illuminance of the room is calculated from the illuminance data, the data indicating the state of the room extracted from the room equipment layout diagram, and the brightness data of the luminaire held in the database, and the luminaire that gives the calculated illuminance Select the type of from the database.

[0007]

According to the present invention, the data of the types of lighting equipment and the brightness of these lighting equipment are held in advance as a database. Further, the present invention uses a room facility layout diagram in which data of rooms is created.

Then, according to the present invention, the following processing is carried out by using these database and the room equipment layout drawing which is made into data.

When the illuminance required for the room is given, the illuminance of the room is extracted from the data of the illuminance, the data indicating the condition of the room extracted from the room equipment layout diagram, and the data of the brightness of the luminaire held in the database. Calculate the illuminance. Next, the type of lighting equipment that gives the calculated illuminance is selected from the database, and the type of lighting equipment that gives the illuminance required for the room is selected.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a schematic view showing an example of a processing apparatus and the like for carrying out the present invention.

A drawing prepared by CAD is used for this processing apparatus and the like. CAD creates a drawing of a building, a room, or the like, and a room facility layout drawing (hereinafter, referred to as an electric diagram) in which a mounting position of a lighting fixture is added to the drawing.
An example of this electrical diagram is shown in FIG. In FIG. 3, the lighting fixture 31 is arranged in the approximate center of the kitchen.

The CAD records the created electric diagram data on the magnetic disk 1 or the like. The electric diagram data recorded on the magnetic disk 1 includes, in addition to the room drawing shown in FIG. 3, room size, height, shape data, ceiling and wall finish material reflectance data, There is also data on the mounting position of lighting equipment.

On the other hand, the processing device 2 holds the data of the types of lighting equipment and the data of the brightness of each type of lighting equipment as a database. Using this database, the processing device 2 uses the data from the magnetic disk 1 to perform the processing according to the processing procedure shown in FIG.

First, the processing device 2 reads the electric diagram recorded on the magnetic disk 1 (step S11). Next, the illuminance required for the room of FIG. 3 is input from the keyboard 3 of the processing device 2 (step S12).

After step S12, the processing device 2 selects one lighting fixture (step S13). Then, the processing device 2 uses the data of the electric diagram read in step S11, the data of the size, height, and shape of the room of FIG. 3, the data of the reflectance of the finishing material of the ceiling or the wall, and the lighting fixtures. The illuminance of this room is calculated from the data of the mounting position and the data of the brightness of the lighting fixture selected in step S13 (step S14).

When the illuminance calculated in step S14 does not reach the illuminance input in step S12, the process returns to step S13. That is, another luminaire is selected in step S13, and the illuminance when this luminaire is used is calculated from the brightness data of this luminaire and the data of the room in step S14.

Steps S13 and S14 are repeated, and the type of lighting equipment that satisfies the illuminance input in step S12 is selected. Then, an electric diagram in which the type of the selected lighting fixture is added to the electric diagram of FIG. 3, that is, the electric diagram shown in FIG. 4 is drawn (step S15), and this electric diagram is output to the display screen 4 and the printer 5 ( Step S16).
Note that, in FIG. 4, the type of the lighting fixture selected by “XX lighting manufactured by XX” is shown.

As described above, in this embodiment, data on the size, height, and shape of the room, data on the reflectance of the finishing material for the ceiling and walls, and lighting equipment recorded in the electric diagram created by CAD are used. Since the illuminance of the room is calculated using the data of the mounting position and the luminaire that matches this illuminance is selected from the database, it is possible to select according to the user's request.

The embodiment has been described above with reference to the drawings. However, the specific structure is not limited to this embodiment, and the present invention is applicable even if there are design changes and the like within the scope not departing from the gist of the invention. Of course, it is included in.

For example, in the embodiment of the present invention, the illumination of the room of the building has been described. However, the present invention can be applied to, for example, selection of a lighting fixture attached to a vehicle created by using CAD, for example. ..

In this embodiment, the electrogram data is transferred to the processing device 2 using the magnetic disk 1. However, the data transfer is not limited to this, and for example, C
If the AD and the processing device 2 are separated, it is possible to move the data using a telephone line.

Further, instead of the lighting equipment as the database, the data of the air conditioner is held, and from the positions of windows and doors shown in the drawing of the room created by CAD,
It is also possible to design the optimum air conditioning by calculating the heat loss and determining the optimum air conditioner.

[0024]

As described above, according to the present invention, the illuminance is calculated using the data-based room equipment layout diagram, and the type of the luminaire that matches this illuminance is selected from the database. The illuminance can be surely satisfied.

Since the illuminance is calculated using the data of the room equipment layout and the database of the types of luminaires, the illuminance calculation can be automated.
