its most likely photoshopped, cos 1, the light intersect will have 2 strong light source from sides, so each line will have 1 side stronger than the other side to show the light coming from which side. in this case, all sides get weaker, means light source from middle. which is not intersection, should be source.
then the source itself is rounded arc edge, no lightsource in intersetion will give a smoothen arc. It can have a circular outburst but not an internal arc. in this case, it will not give a star shape burst cos the aperture is wide open as seen from the image.
Sometimes this is call... shooting something out of nothing. A kind of brainstorming exercise.
It could be a useful reference for future work/ assignment/ project etc. just like an artist sketch book.
