How does interior lighting using fiber optics work?
Posted by CharlesC on Aug-28-2010
Just interested in how this works….
Well hopefully I don’t miss this question completely. I’ve never really seen fiber optic interior lighting… But the principle of fiber optics is based on total internal reflectance. It’s a phenomena observed when light is passing in something of a high refractive index and attempts to leave into something of a lower refractive index but it is less than a certain "critical" angle.
Basically this means you can trap light in plastic/glass tubes if you keep the angles gradual enough. So if you point these tubes at something, voila, lighting.
