Yes, there are other physically based lighting concepts. You can have a look at image based lighting and Area Lights (such as Sphere or Tube lights).
If you have access, have look into Physically Based Rendering, if i recall correctly, that has a chapter or two about non-point lights.
Free on the internet is for example Real Shading in Unreal Engine 4. Furthermore, there is the Physically Based Lighting at Pixar paper, although I am not sure how real-time suitable this is.
This should give you a starting point into the topic. You should read up on it and then perhaps come back, if you have more detailed questions.
