I am working on a project to bring light into a bunker. The bunker is 3-4 meters below the ground.
I am looking into bringing natural light into the space, instead of using electricity. The space is difficult to access and light must therefore be transported by flexible cable for about 20 meters from the surface to the areas I want to light up. I am thinking of pipe around 1 cm diameter maximum.
I am looking into a cheap solution to create an optical pipe that is effective at transporting light.
- I am wondering what techniques are typically used.
- What kind of pipes would you use ?
- Is it possible to fill the pipe with other materials to increase its effectiveness ?
