Light Guide Films: How they work.

Our Light Guide Films (LGFs) are designed for effective use of LED edge light sources.   Light from the LED sources is internally reflected down the length of LGF to the various viewing areas.  The Localized Micro-Lens Arrays  redirect light out of the film to the viewer only where it is needed (to each logo, image, key or button) by layout design.   This new technology patterning allows light to be efficiently and uniformly directed where light is desired in a very low profile film. 

Light Guide Film Examples

• Very efficient use of light only to areas to be illuminated.   Patterns of MicroLenses areas designed by Customer software such as CAD or other standard design software.  
• More Efficient use (and reduced numbers) of LED sources
• Very Thin Form Factor.
• Roll to Roll Film Manufacturing for Low Cost
• Software Designed Patterns for Precise Light Control.
