Control Panel Lighting Simulation - Ansys Speos Demo
In this tutorial, we will create a lighting panel simulation for spells using Ansys Speos. We will utilize a CAT file that was previously created. Let's begin by opening the CAT data file.
Step 1: Setting Up Material Properties
First, we need to describe the material properties for our backlight lighting system. Ensure you save your file to avoid data loss.
- Material Properties for LEDs:
- Rename the material for LEDs.
- Select the LEDs by holding the control button and clicking on them.
- Describe the properties of the LEDs.
- Material Properties for the Panel:
- Display the panel, which is a plexi panel covered by a reflective coating.
- Rename the system name to PMMA and set the refractive index to 1.49.
- Indicator Text and Arrow:
- Zoom in to work on the indicator text and arrow.
- Describe the surface roughness by changing from volume to face properties.
- Select the appropriate surface roughness from the library.
- Back Surfaces:
- Describe the back surfaces to allow ray injection inside the panel.
- Select a different roughness level for these surfaces.
Step 2: Creating the Source
With several LEDs behind the plexi panel, we need to describe the source properties:
- Select the LED dies as the light-emitting surface.
- Set the lumen output to 850 lumens with a viewing angle of 110 degrees.
- Change the spectrum from green to red to observe color changes.
Step 3: Creating the Detector
We will use a radiance detector for this example:
- Modify the radiance detector to focus on the indicator arrow and text.
- Adjust the resolution by changing the sampling rate to 1800 for better clarity.
Step 4: Running the Simulation
Finally, we will run the simulation:
- Go to the light simulation tab and select direct simulation.
- Select the main object, sources, and detector for the simulation.
- Run the simulation and observe the results in the viewer.
In the viewer, you can observe the radiance map, including the on/off states and arrow indicators. Adjust the luminance to see changes in candela per meter square at different points.
Conclusion
This demonstration shows how Ozen Engineering, Inc.'s Ansys Speos can effectively simulate lighting panels. We hope this example is helpful for your projects. Thank you for watching!
Today we are going to make a lighting panel simulation for spells, and we plan to use an Ansys Speos demo. We will start by opening a .cat file that was created before.
In Speos, we will describe the material properties, surface properties, then create source properties, a detector, and finally make the optical simulation. First, we will create material properties for our backlight lighting system. We will start by saving our file without losing any data.
Here are the material properties we can describe: 1. LEDs: We will rename it and select the panel. The rest of them are LEDs. We will select all of them, then click to create the LEDs. 2. P.M.M.A.: We will select the material and click it. This is the material property we have. P.M.M.A.
has a refractive index of 1.49, which we will change. 3. Indicator text and arrow: We will zoom in and create a surface property for the face. We will change the type from volume to face properties and select a mirror or optically polished surface.
We will then select the surface roughness level from the library. 4. Back surfaces: We will describe surface properties again with a different roughness level for the entrance point for LEDs.
We will select face properties and go to the library to select surface roughness 2. Now we will describe the source. We have several LEDs behind the plexi panel. We will select the surface and the LED dies as the light emitting surface.
We will describe the properties of these LEDs, such as the lumen output, intensity type, total angle, and spectrum. Next, we will create the detector. We will use a radiance director for this example. We will modify it to observe only the indicators, arrow, and text.
Finally, we will go to the light simulation tab and select the object, sources, and detector to include in the simulation. We will then click to simulate, and once it is finished, we will open the window to observe the detector. We can then go to the viewer and observe the radiance map.
We can see the on and off states and the arrow indicator. We can also observe the candela per meter square in that point. Thank you for listening. We hope this example is helpful for simulating lighting panels using Ansys Speos.
