Light Pipe Design

Light pipes or light guides are commonly used in consumer electronics, avionics, instrument panels, switches, indicators, and display devices.

Typically, light pipes are clear plastic optical devices molded from a single piece of material, and are used to guide light to where it is needed. Gentle curves are used to steer light by Total Internal Reflection (TIR) combined with sharp edge corners that serve as mirrors. Hollow light tubes are also used in daylighting applications for buildings, tunnels, and other structures.

Example TracePro applications for light pipe design are:

  • Automotive instruments and dashboards
  • Aviation light panels, avionics, switches, and indicators
  • Displays, light panels, mobile devices, HDTVs, and digital signage
  • Consumer electronic displays, knobs, and switches
