DIALux Tutorial 3 Creating different RGB Color Changing Scenes
DIALux Tutorial 3 Creating different RGB Color Changing Scenes
This third tutorial explains the following:
1. Creating control group
2. Creating light Scenes
3. Put the right value for the RGB
4. Saving and restoring camera view.
5. changing the light scene in cad
To start this tutorial you have to make an RGBW wall washer line arrangement as explained in the second tutorial where it could be found under the following link
http://ezzatbaroudi.blogspot.com/2011/01/dialux-tutorial2-how-to-make-offset-and.html
The wall washer for this tutorial is ERCO 37838, but you also can use any other RGB or RGBW (RGB with white light).
After you place ERCO 37838 for one of the wall as explained in tutorial 2, select this arrangement (all the luminaries )in the project manager left side and right click the mouse to open the context menu and then select add to control group then new control group as could be seen form next image
You can change the name of the control group by selecting it in the project manager (left side of the software) and then changing the name form the property window (The Inspector) as shown below.
Select the control group and right click the mouse and select add to light scene then new light scene.
Select the new light scene form the project manager and rename it to red scene form the property window
Then expand the scene list by the clicking on the + sign near the red scene in the project manager
And select wallwasher group inside this list as could be seen form next image
After that put the dimming values shown in the property window zero for all luminous emittance except for the red luminous remittance as could be seen form next image.
The red luminous emittance for this luminaire is the second one, this luminous emittance should remain 100 % the other should be 0%
You can know the color of luminous emittance of an RGB or RGBW luminaire simply by selecting the luminaire second property which shown after you expand the arrangement by clicking on the + sign and selecting the lower row as could be seen in the next image.
Then from the first tab technical data tab you can select the sub-tab luminous emittance form the first to last sub-tab as you can see form next image.
For ERCO 37838 you can read the following information
The first sub tab the color is warm white with 870 and 15 watt
The second sub tab is red with 100 lumen and 3 Watt
The third sub tab is Green with 269 and 5 watt
The fourth sub-tab is Blue with 101 and 5 watt
Also you can open the second tab which is the light colour and see the color of the luminous emittance
Now select the wallwasher control group and add it to a new light Scene and rename the new Scene to Blue Scene
And put the dimming values for all luminous emittance in this scene zero except the blue one as shown below
You can add as many scene as you wish and change the color to the desired color e.g. you can put 5% white, 70% red , 25% green in one scene.
Now let’s try one more new scene for this tutorial.
Add new scene and rename it to cyan and put the following dimming values
Now show the 3D view form the tool bar
And rotate, zoom, move and roam form the tool bar
Until you have a good view of the wall that is being washed by the wall washer like the one below
Now save this view so you can see it any time by clicking ctrl key and any number between 1-9, alternately by going to cad menu and then save camera view and then choose save position 1
You can save up to 10 different positions and to restore that position simply press alt key and the number of the poison or form the CAD menu and select the position form redo camera view.
Form the color tab, apply the white color to walls by drag and drop option of the mouse so you can see the reflection of the RGBW colours in a better way.
Now start the calculation
You can change scenes by the tool bar buttons and also you can see the dimming values as you can see in the next image.
Also you can change the scene in the project manager by selecting the required scene and then right click the mouse and select the required scene
Use light scene for CAD as shown in the next image.

Dialux Tutorial_How to create a cove for cove lighting in DIALux
How to create a cove for cove lighting in DIALux
This DIALux Tutorial not only to explain how to make a cove for indirect lighting but also explain how to
1- Use extrusion volume in different way.
2- How to use subtract and combine command.
3- How to use help line with offset for parallel lines.
4- How to center any object inside a space by one command.
5- How to use the Align aids tool that make the work much faster.
6- How to show the align in the tool bar.
7- How to utilize the 3D light distribution display.
8- How to find the Iluminace and luminance values from the 3d view.
In this tutorial you will learn how to make a cove similar to the one in the following image
The cove dimension will be 4 meter by 5 meter and the other dimension will be as follows:
First make a room with dimension of 5×6 and height of 3 meter and don’t forget to click on OK, otherwise you can’t move to the next step.
The cove will be divided to two parts as illustrated in the following image:
- The upper part
- the Base
First you will learn how to make the base then how to make the upper part and combine them together.
The Base
1-First select the object tab
2-selsct standard elements if not selected.
3- Select the Extrusion volume.
4- put the following dimension
X=5, y=4, H=0.1
5- Click on paste and then Ok.
Don’t forget to click on Ok, otherwise you cannot make any further operation.
After that ensure that the extrusion volume is still selected. And then while selecting the extrusion volume right click the mouse and select align and distribute menu and choose the command centered in place.
This command will ensure that the extrusion volume is placed in the middle of the room
You can see the 3D view by clicking on the relative button as shown on next illustration
Put the color white from the color tab on the object by drag and drop option, just pull the color by the mouse and drop it on the object.
Place another extrusion volume with the following dimension.
4.974×3.974 meter and height of 0.087 meter
This is because the edge of the cove is 13 mm and the we have two edges at each side
2×13=26 mm
After placing the new extrusion volume don’t forget to click on paste then OK.
Select the new extrusion volume form the corner as illustrated in the red square to the other corner of the first extrusion volume.
Select both extrusion volume by the mouse while holding shift key down.
You can also select both of them form the project manager on the right side under the object folder, just make sure you are on the project tab not on any other tab as illustrated by the red square on next image.
While selecting both objects (extrusion volumes) right click on mouse and select form align and distribute menu the command
Align centrally in x
Then repeat this step again and select in this time.
Align centrally in y
In this step we placed the second object in the meddle of the first one by the help of align command.
By the way you can show the Align menu in the tool bar by mouse right click and select the align as illustrated in the next image
Select both objects and then click on the align to top button in the tool bar as shown in the next image
Name the first object as 01 and the second one as 02 by selecting the object in the project manager and putting the name in the name field as shown in the illustration.
Select both objects 01 and 02 on the project manager with holding shift key and then open the context menu by right click the mouse and then select subtract as shown on the next image.
Make sure that 01 appears in the object form which should be subtracted, if not 01 then select 01 form the drop down menu. After that click on subtract button as shown in the red box in the illustration
After the subtraction put the white color for the object as done earlier form the color tab.
THE UPPER PART
You will use the help line to make an offset line form the base to create the upper part.
Select draw help line form the tool bar.
The icon will be as shown in the red box shown in the next image.
After selecting the draw help line
Draw it to the upper line of the base as shown in the illustration (red line).
After you draw the line put in the box of parallels spaced apart box a value of 0.2 meter.
This box is in the left side.
If the line is placed outside of the base then make the value -0.2 by putting – minus sign before 0.2 to make the offset inside the base
You have put the value of the offset 0.2 based on the diminution as shown in the next image.
The distance between the base and the upper part.
Repeat the help line so you have 4 help lines with an offset of 0.2 meter at four sides as in the illustration.
Remember the offset have to be inside the base if not then you have to change the sign to minus sign(-0.2)
From the object select the extrusion volume and drag it inside the room or click on past
then right click and select form the context menu draw polygon(this step has to be done before clicking on the OK button, otherwise you have to select the object and right click the mouse and select EDIT command )
After that place the line set at the four corners of the offset lines as shown in the illustration
once the four points are done,then right click again and choose close to close the polygon as you can see form next illustration
On the height form the project manager on the left side put 0.3 meter which is the height of the upper part
Put the same color white as done earlier form the color tab
Select the base and the upper part by holding down the shift key and right click and select form the context menu the combine command as shown in the side image.
Select the front view form the tool bar.
Move the cove to the ceiling by selection one of the upper dot “corner”
In the plan view select the cove and right click the mouse
Form the context menu select centered in space form the align and distribute menu
Put the white color on the ceiling so you can have the same color of the cove and ceiling.
After completing the cove now is the time to place a luminaire for the cove lighting, you can select form any catalogue any fluorescent batten luminaire, LED or any other source for indirect lighting.
In this exercise, the selection was made form Osram catalogue by selecting 1×35 W and 1×14 W T5 batten luminaire.
After the selection of the luminaire place a line arrangement form the relative icon in the tool bar as shown in the next image
Ensure you are selecting the line arrangement so you can see the property window on the left “in the project manager”
open the general tab
put the following values
in Quantity box 3
in Distance box 1.5 meter
While you are still selecting the line arrangement.
Open Rotations tab
And put rotate the line 180 in Y of the individual luminaire,
In this step you rotated each luminaire to be upside down to illuminate the ceiling not the floor.
You can see the light destruction in the front view or side view to ensure that the light distribution to the ceiling side not to the floor side by activating the 3D light distribution display button in the tool bar
Move the line in to be placed inside the cove in floor plan view.
Also move the line to be inside the cove in the front view
Copy the line arrangement to the other sides of the cove, so you have line arrangements at for sides
You can increase or decrease the number of luminaire at each arrangement by selecting the arrangement and changing the quantity as explained earlier
After putting all the luminaire you can run the calculation by clicking the start calculation button in the tool bar
After the calculation is done you can move the cursor of the mouse and looking at the lower left part of the software where the value of Iluminace and luminance is shown
The location of Iluminace and luminance values are illustrated by the red boxes
