Light guides, are customized plastic injection parts, based on their shape, as well as material and surface texture transmit, distribute or bundle light.
Additional printing or applying of reflective films, combined with diffusion films can enhance the optical properties and also reduce light loss.
For example, classical application areas for light guides are:
- Diffusing panel at Side-LED-Backlights. They sprinkle the selectively lateral irradiated light and allow a homogeneous illumination over the entire surface.
- Diffusor panel in Bottom-LED-Backlights. They spread the light output from a LEDs assembled printed circuit board, and allow a uniform illumination over the entire surface.
Light guide for illumination of individual areas or symbols by distant light sources. The light from one or more LEDs, can be directed via a light guide to the point to be illuminated.
