“This video shows how to use the Light Expert tool. This option show rays in the 3D view to identify specific light paths going in a specific target area. With Light Expert, you can identify a particular light path reaching a sensor area. With Light Expert, you can verify that the lens of your luminaire does collimate the light from the LED. You’ll see how to make, on the other side of the case, a reflector, that will reflect the light from the TIR lens onto the ground, using Optical Surface.
The next video in this series shows how to pattern the light module.”
