Continuing the discussion from Cotty's gallery images:
To start with, these points are very important:
- model as accurate as possible (to scale, with all relevant details like active emitting areas, lenses, …)
- use adequate materials
- instead of modeling the LED, you can try to create a IES light with the desired lightning pattern
Since V-Ray is a physically based raytracer, it is possible to get very realistic results with the right setup.
Do you have an example of the current result and the ideal goal?
I imported the profile and cover (2D) from dwg
Made the 3D model in SU.
Made a mesh light with the help of V-ray.
I calculated the lumenoutput we have with the LED strip we would use with the specific length and used this to set the settings for the light source in V-ray.
I used the materials available in V-ray.
I only have basic knowledge of creating my own materials. Still learning.
If you know a course I could take… Or follow that would be great.
That reminded me of this old SketchUcation thread: Render this: L.E.D lighting • sketchUcation • 2
Most is probably outdated by now.
(And I asked similar question in 2008 on the old ASGVis forums, which never got an reply (How do you model an LED light? - Chaos Forums). Maybe I’ll finally learn this myself! )
some old examples from me with optical elements …
and a simple rectangle with an IES profile assigned:
Did you figure out how to get the right result?
