There are several rules of thumb to keep in mind when integrating light pipes in product design. First, the light pipe has to be designed in such a way that it captures the maximum possible amount of light from the LED and minimizes the amount of light that is reflected away. Once the light has been correctly captured, the design must focus on having the light leave the light pipe in the right location. Light travels on a direct course within straight light pipes. More consideration needs to be given to effectively route light inside angled light pipes. There are a variety of options available for working around objects. Advanced ray tracing/prototyping of the design geometry to provide a high rate of light transmission through the exit surface with minimal loss is desirable.
