Tutorial for Warehouse Lighting Design

Page | 1

Design requirements:

Luminaire: Nikkon AL25400 M0400 6407 c/w EYE IWASAKI MF400X/U lamp

Lux level: 300 lux

Mounting height: 8.5m

Room dimension: 48m (L) x 20m (W) x 13m (H)

Slope of roof: 25°

1. Click on New Interior Project to launch DIALux’s template for indoor design. DIALux will then

direct to screen as shown in Figure 2.

2. Edit the Length, Width and Height according to the values stated in Figure 2 and click on OK

button.

Figure 2

3. The slope of the roof is given at 25° and sloping on both directions (Gable roof). Calculations is

done as following:

Length of roof (in one direction) = 10 m

Slope of roof = 25°

Length of a = 10 (tan 25°), tan = tangent in geometry terms

= 4.663m

Length: 48.000m Width: 20.000m

Height: 13.000m

4. Click on Object tab in Project Manager, then select Room elements � Sloped ceiling. From the

previous calculation, we have determined then length (10m), width (length of the room = 48m)

and height (length of a) of the sloped ceiling. Insert the values as shown in Figure 3 and click on

Paste.

5. As gable roof is symmetrical, right-click on the Sloped Ceiling and select Copy along a line.

7. As the roof is mirrored, the angle of rotation of the generated Sloped Ceiling has to be changed.

Click on the Sloped Ceiling and edit the values as shown in Figure 6.

9. Click on Luminaire selection tab at the bottom of Project Manager, as shown in the red circle in

Figure 8. Select NIKKON from the databse and double click with mouse, Nikkon’s catalogue will

pop up in a new window with the range of luminaire to be chosen from (Figure 9).

12. Go back to the Floor Plan view by clicking on the Floor Plan icon. Draw a help line accross the

centre of the room by clicking on the help line icon and draw a line at the center of the room as

shown in Figure 13.

13. Click on Field Arrangement icon and go to Arrangement tab and click on Symmetrical Within in

Arrangement column.

14. Conduct some simple calculation to determine the number of luminaires to be used.

Size of the room: 48m (L) x 20m (W)


To start, assume the spacing between luminaires to be the same as mounting height.

In the x-direction, we will have 48m of space. Dividing 48 by 8.5, we will have 5.65. Round it up

to 5 numbers of 8.5m of spacing gives of 6 luminaires in the x-direction.

In the y-direction, divide 20 by 8.5 will give us 2.35. This will mean 3 numbers of luminaires in

the y-direction.

15. Click on the Mounting tab and put in the values as shown in Figure 15.

17. Click on Paste button to see the arrangement. Note that the arrangement is too near to the

walls of the room in the y-direction.

18. Click on the Positions tab and edit the values as shown in Figure 18. Note that the distance in the

y-direction has been reduced from 8.5m to 7.5m.

19. Drag the arrow head towards the intersection point as shown in Figure 19. Click on the Start

Calculation icon to conduct the calculation.

20. Start Calculation window will then appear on the screen. Make sure all the fields are checked

and click on OK to start the lux calculation. Calculation will be done automatically and the

resulting lighting scene from the simulation will be shown (Figure 21).

21. You could also click on False Color Display icon for a clearer indication of the lighting output

from the luminaire on the roadway. The numbers can be edited to show a clearer picture of the

lighting level on road surface.

Figure 22

22. To view the lighting level in numbers, click on the Output tab in Project Manager. Click on the

“+” sign beside Room 1, followed by Room Surfaces, Floor and Value Chart (E).

23. The numbers in the box shown in Figure 24 indicates the lux level on that particular spot of the

roadway. The abbreviation on the sheet is as follow:

Eav - Average lux level

Emin - Minimum lux level

Emax - Maximum lux level

u0 - Uniformity

Figure 24

24. Finally, the results can be generated as a PDF document or printed out. You can select the

results to be generated/printed by checking the box next to the options (Figure 24).

25. You can then create a custom project cover page by clicking on the Project tab under Project

Manager. Then click on Project 1. Under the Project tab, edit the Name and Description for the

Project. Name will be the project’s name and Description will consist of the luminaire being

chosen to use for this particular project and its revision (eg. Rev 00 for a new project, Rev 01 for

the first revision).
