Illuminated Signage in DIALux evo
This Tutorial for advanced users if you are not familiar with DIALux evo then start with other tutorials
the current version of DIALux evo doesn’t support self luminance , this tutorial help you create an illuminated signage by using some tricks and tips
Create a text or shape by using any software the easiest way by windows Paint
the text/Shape should be whiten with black background
Create a frame of the signage
in this DLX-T I subtracted two cubes
Subtract 4 x0.8×0.15 cube from 4.1 x0.9×0.15
Place a 3rd cube with 4 x0.85×0.05 and align it to be mid of X ,Y,X of the frame
Then Subtract cube 3 from the frame to get a niche where you can put later a strip light inside
go to material and select black color with 0% reflection value and apply it to the inside surfaces of the frame
insert strip light inside the two niches, if you dont have a source for strip light then you can go to lumsearch.com
search for 5050 red and select the first search and insert the phototropic file inside DIALux by click on the Dx icon
if the Dx icon is not active then the manufacturer doesn’t support this function in the lumsearch then select another
insert the red strip in the bottom niche and search for 5050 blue then inset this blue strip in the top niche
by default most strip light distribution will be downward so make sure to activate the Show light distribution curve and rotate the bottom strip light upward to illuminate inside the frame
the top strip however should be downward.
insert multiple strip length to cover the 4 meter , I have used 4 strips each one has 1 meter length at bottom and 4 strips at top.
insert cube 4 with the following size 4.05 x0.1×0.85 then align it back of the frame Y
center in Z,X
create texture material with the create text with size of 4.05×0.85 and reflection value of 5%
then calculate and render to get the illuminated signage!
however there will be spill of the strip light in the space to avoid this follow next step
to avoid the spill light copy cube 4 and change the back color of it to black 0 Reflection value and the front side of it make it Transparent with 10% transparency and reflection factor to 1 or 0
after applying new texture values then align this cube to be centered front with the frame
you can push it slightly back to create a gap but should be ahead of the strip light.
after you put this then you can calculate and see the results without spill light!
since the strip light is used for creating an effect and we are using low transparency values then you can go to the lamp properties in DIALux and increase the lumen value by many times, i used 2000 lumen for blue and 3000 lumen for red for each Strip.
you can use different background and create different effect with other values of reflection and transparency but the white text/shape with black background seems to have the maximum effect. while using lighter background will minimize the effect
of course you can add logo or any shape to the text
