Abstract

PURPOSE:To make a lighting plan suitable by computing an indoor shadow part to be less than necessary illuminance by the influence of a planning object and outputting this part as a picture to a display device visually distinguishably from the other part. CONSTITUTION:The inside of a room, for which a tank 7 and a duct 9 are set, is surrounded by a building body wall 10, a ceiling 12 and a floor 13. Then, when it is planned to provide lighting facilities and equipments 8, the illuminance in the inside of the room is computed and the illuminance on the surface of the planning object in the inside of the room is computed. In the case of an example, in which the duct 9 is provided on the left upper part of the tank 7, to be shown in a figure, a light from a light source provided on the ceiling 12 is shaded in the upper part and a shadow part 11 is generated in the side of the tank 7. When the illumination of such a shadow part 11 is lower than a standard by being collated to a construction standards regulations, the picture display of the shadow part is specially colored and recognized to a lighting facility planner. Thus, the lighting facility plan can be made suitable.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the installation of lighting equipment in buildings and plants in construction plans, where shadow areas occur due to the installation of other equipment, piping, etc. This invention relates to an in-building lighting equipment planning support device that allows lighting equipment to be planned effectively by determining the area in advance through computer simulation.

[Prior Art] Conventionally, CAD devices have generally converted the data of the design object into image data and displayed it on a display, which can be visually checked to confirm the design of the design object. It looks like this.

[Problem to be solved by the invention] With conventional CAD equipment, when planning lighting equipment in a building,
There is nothing that realistically displays the illuminance level and illuminance distribution of arbitrary areas of various planned objects arranged three-dimensionally.

When installing lighting equipment in a building, there may be cases where the required illuminance in the work area cannot be secured due to shadows caused by the installation of equipment, piping, ducts, etc. inside the building. Conventionally, the lighting equipment was planned using methods such as calculating the illuminance from the positional relationship between the planned object and the lighting equipment and studying it on a desk. For this reason, it is sometimes necessary to install additional lighting equipment on-site, which causes an increase in costs.

The purpose of the present invention is to solve the above problems.

Plan the basic layout of lighting equipment in any room in the building, determine the illuminance distribution in any area due to the light source, and use computer simulation to display the illuminance on the surface of any planned object. In addition to making it possible to consider whether there will be spaces where the illuminance does not reach the standard level, display information to the planner in a way that allows spaces with illuminance below the standard level to be distinguished, for example by changing the color. To provide a lighting equipment planning support device for buildings.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an input device, a storage device, and performs arithmetic processing on data from the storage device and the input device according to a processing procedure stored in the storage device. It consists of an arithmetic processing unit that executes the processing and a display device that displays the arithmetic processing results of the arithmetic processing unit, and the arithmetic processing unit displays the layout data of the building contents planning object read from the storage device and the lighting equipment planning setting conditions input from the input device. A means for calculating the illuminance distribution on the surface of each planned object in the arrangement of lighting equipment inputted from the input device based on the data and outputting it as an image on a display device, and a means for calculating the illuminance distribution on the surface of each planned object in the arrangement of lighting equipment input from the input device, and a means for outputting this as an image on a display device, and a means for calculating the illuminance distribution on the surface of each planned object in the arrangement of lighting equipment input from the input device The present invention provides an in-building lighting equipment planning support device characterized by having means for calculating a shaded portion and outputting it as an image on a display device so as to be visually distinguishable from other portions.

[Function] The in-building lighting equipment planning support device of the present invention calculates the illuminance of the surface of each planning object according to the intensity of the light source of the lighting equipment scheduled to be installed in the building, and determines the surface brightness. , this can be displayed as a display image. In this case, since the incident angle of the light source can also be calculated depending on the installation position of the lighting equipment,
Since it is possible to check in the displayed image areas where light is blocked by planned objects such as ducts and are in shadows with less than the required illuminance, lighting equipment planning can be made more appropriate.
