Ansys Speos: Light Guide Demo
Hi, today we are going to make an optical simulation demo for designing a light guide. Light guides are generally used in the automotive industry and consumer electronics, but they also have applications in various other fields. Today, I will explain step by step how to create a light guide in SPHERES.
Creating a Light Guide
- Go to the Sketch tab and create an arc with a distance of 60 millimeters.
- In the Design tab, navigate to Optical Part Design and select Light Guide Segment.
- Save the file to prevent data loss.
- Describe the curve for the light guide and select the direction.
- Choose the body type: circular shape, constant profile, or prism option.
- Adjust the profile diameter and create gaps of 1 millimeter at the start and end points.
- Modify prism geometries and radii as needed.
Adding a Light Source
- Insert an LED at the starting point of the light guide.
- Describe the light-emitting surface properties in the Light Simulation tab.
- Set the luminous flux to 850 lumens and use the Lombergin intensity type.
- Adjust the spectrum to 540 nanometers.
Defining Material Properties
- Click on Material Properties and rename it to PMMA (acrylic).
- Select the LED material as aluminum and set it to opaque.
Setting Up Sensors
Sensors are crucial for this example. We will use a radiance director to focus on the exit surface of the light guide. Adjust the size and position of the director as needed.
Running Simulations
- Direct Simulation: Observe the radiance map at the exit surface. Include relevant objects in the simulation.
- Interactive Simulation: Observe ray behavior inside the light guide. Adjust display settings for better visibility.
Conclusion
Today, we described a light guide and performed simulations for ray tracing and observing the radiance map. We also observed how rays behave inside the light guide geometry. Thank you for listening to this tutorial. I hope to see you in another optical simulation demo by ANSYS Speos.

Hi, today we are going to make an optical simulation demo for designing a light guide. Light guides are generally in use in the automotive industry and consumer electronics, but they can also be found in various other fields.
In this talk, I will explain step by step how to create a light guide in SPHERES. We will start by going to the sketch tab and creating an arc with a distance of 60 millimeters. In SPHERES, we can find the design tab, which contains the optical part design.
Inside this, we can find the light guide segment. Before we create the light guide, we should save the file to prevent any loss of data. Next, we will create a light guide by clicking on the light guide segment and selecting the desired curve.
We can modify the general body type as a circular shape or a constant profile. We can also use only the prism option and adjust the profile diameter accordingly. After creating the light guide geometry, we need to add a light source.
For this, we will add an LED at the starting point of the light guide. We will then describe the light source properties, such as the light emitting surface and the luminous flux. Next, we will describe the material properties of the light guide.
We will use PMMA or acrylic for the light guide and a kind of aluminum material for the LED. We will then describe sensors for our system. For this example, we will use a radiance director to focus on the exit surface of the light guide. Finally, we will perform two different simulations.
The first one is a direct simulation, where we observe the radiance map of the light guide at the exit surface. The second one is an interactive simulation, where we observe the rays and how they behave inside the light guide. This is the way how we can create a light guide in ANSYS Speos.
Thank you for listening, and I hope you have learned something new. In the next tutorial, we will cover the topic of Bacillus infrared vu discharge, early preparatory emergencyzać. We will do it in the setting to bug our device.
It's very important to have a backup signal in our device for the geometry inside the system. As a summary, today we have described a light guide and made a simulation for ray tracing and observing the radiance map in the director.
We have also observed the rays and how they behave inside the light guide geometry. Thank you for listening, and I hope to see you in another optical simulation demo by ANSYS Speos.
