Distribution by zone

The "Distribution by zone" option allows you to enter a grid layout of luminaires covering the area selected by the user.

To do this, left-click on one of the zones that have been imported or previously entered into the model. This generates a polygonal layout that fits the zone. The side of the selected zone will determine the orientation of the X-axis of the layout. The program displays luminaire alignments in the X-direction in red and those in the Y-direction in green.

During the process, the program displays the following dockable window for defining the distribution parameters:

• Lighting type
  • Interior
  • Exterior
  • Emergency
• Luminaire
  • Catalogue / Selection
    Reference to the manufacturer’s catalogue and luminaire model selection. Using the “Select a luminaire from the library” wizard, available on the right, the program allows you to select luminaires from “Manufacturer catalogues” or the “Generic elements library”. These types of elements can be created and edited via the “Catalogues” and “Indoor luminaire types”, “Outdoor luminaire types” or “Emergency luminaire types” options, respectively, available within the “Project” section of the main toolbar on the main interface.
• Axis orientation
  Defines the orientation of the luminaires by applying an individual rotation about their Z-axis. To do this, you specify whether the horizontal plane of origin of the photometric curve is aligned with, or oriented at a specific angle to, the reference line:
  • Aligned
  • Rotated by 90°
  • Rotated 180°
  • Facing 270 degrees
  • With user-defined orientation
• Distribution by zone
  Adjusts the lighting layout settings.
  • Position
    Indicates whether the distribution of luminaires is defined by entering their number or a specific distance between luminaires. The program allows you to "Enter only luminaires that are completely within the zones" by ticking the relevant option. This option automatically excludes any luminaires whose geometry lies partially outside the distribution polygon.
    • By quantity
      The luminaires will be distributed evenly according to the specified number.
      For each direction (X / Y), the following is specified:
      • Alignment
        Specifies whether the luminaires are arranged "Symmetrically", aligned along their "Outer edges", or with their centres aligned with the sides of the rectangle ("Centre-to-centre").
      • Number of luminaires
        Enter the number of luminaires per row.
    • By distance
      A fixed spacing is set between luminaires, measured between centres or between edges.
      For each direction (X / Y), the following is specified:
      • Alignment
        Defines how the luminaires are positioned in relation to the boundaries of the distribution. The luminaires can be arranged "Symmetrically", aligned along their "Outer edges", or with their centres coinciding with the sides of the rectangle ("Centre-to-centre").
      • Spacing
        Indicates whether the distance measures the spacing "Between centres" or "Between edges" of luminaires.
      • Distance
        Enter the distance between luminaires.
• Automatic distribution
  Calculates the optimal number of luminaires required to achieve a target illuminance. To do this, once a luminaire model and a zone have been selected, the program automatically adjusts the distribution parameters to approximate an “Average maintained horizontal illuminance”, which must be entered by the user. The “Estimated illuminance” based on the generated parameters is displayed on the panel.

Once you have confirmed, the program generates and positions the luminaires according to the defined settings. If necessary, the position or properties of the luminaires can be edited individually at a later stage.
