Designing a Lighting System for a Structure

  1. Mar 6, 2009 #1
    I wish to mathematically represent point light sources inside a structure, and figure out how much like is scattered throughout the structure.

    Specifically, I have lighting values of a certain amount of lux, and I need to ensure that the structure has a minimum of (certain value) lux touching all surfaces (maybe excluding things like shadows under tables). I don't want to go overboard on power consumption, though.

    How, mathematically, should I go about figuring out how to do this? I'm thinking of simplifying the structure to something like a rectangular prism, or even just a hollow sphere of equal surface area.

    I'm very confused at this point and I don't really know where to start.

    Would it help to model the interior of the structure in a ray-tracing programme?

    The only program I know about that is capable of giving actual lighting values on different surfaces is Radiance, and I don't have AutoCAD to interface it with.

    At this point, I just want some real basic estimates that I can calculate by hand. I'm talking about big simplifications, because this is just a preliminary design for the lighting system. Extremely rough estimates that are only good for about an order of magnitude approximation.

    I don't want to simply take the light intensity in lumens and divide by the interior surface area of the structure. I want to do something a little bit more detailed than that.

    I would know the albedos of the different components of the interior walls/floor/ceiling.
