There are two basic types of LED light pipes – rigid and flexible. A rigid light pipe is produced with a hard plastic material and will have either a vertical or a right-angle construction; it is capable of redirecting the LED’s light output to the desired location with minimal loss of intensity. Rigid light pipes are ideal if the LED is mounted on a board immediately behind a front panel. Flexible light pipes are constructed with an optical grade plastic material that provides less rigidity, allowing them to transport light from a board at custom, user-specified subtle angles ensuring easy integration around existing components. Both rigid and flexible light pipes can come in single or multi-unit configurations. A quality multi-unit light pipe will be designed to ensure there is no color bleed between adjacent light pipes.
