This process really reminds me of the way that you calculate electric fields. Specifically the idea of finding the contribution of a differential amount of charge, then integrating across some object carrying that charge. It feels like generating light from a long fluorescent light bulb would be a similar calculation to finding the electric field generated by a bar of uniform charge
