Light guides from Printec-DS
The use of light guides for key lighting ensures the optical wow effect in many keyboards and customer-specific input solutions. The key factor here is how light guides are used. Because the controlled passage of light through a plastic conductor requires a lot of know-how and development work. The effort is worthwhile, however, since an optimally adapted light guide provides a means of homogeneously backlighting larger areas through the light of a single or fewer LEDs. In the long term, the development of a light guide can be worthwhile, since the reduction in the LEDs installed on the circuit board and the inexpensive reproduction of the light guide save manufacturing costs.
3D modeling
As a rule, a light guide must be integrated into an existing concept. The arrangement of the buttons should not change and the space available is usually very small. Nevertheless, we always succeed in finding a suitable solution that does not restrict the functionality or the design of the planned product. Combining these requirements in a small plastic light guide is the highest level of development and is realized by our construction with the help of modern applications in the form of a 3D model. Based on this model, a light guide calculation can be carried out and the later component can be produced.
