Light emitting panel assemblies |
July 29, 2008 |
| Light emitting panel assemblies include a light guide having a pattern of individual deformities of well defined shape that are projections or depressions on or in at least one side of the light guide. At least some of the deformities are quite small in relation to the width and length o |

Light redirecting films pattern of variable optical elements |
April 29, 2008 |
| Light redirecting films and film systems include a thin optically transparent substrate having a pattern of individual optical elements of well defined shape on or in the substrate. At least some of the optical elements may vary at different locations on the substrate to redistribute |

Method of selecting a light redirecting film |
August 15, 2006 |
| The method of selecting a light redirecting film or optical panel includes the steps of providing a length of film or substrate having a pattern of optical elements that varies, then selecting an area of the film or substrate that has a pattern of the optical elements that best suits a |
