High color saturation light controller and lighting device therefor

摘要

A highly color saturated light modulator includes a transparent substrate, printed image layer and a protection layer on the printed surface. The degree of color saturation of images on the modulator is greater than 40% and overall transmission between 15% and 95%. Lighting devices with the light modulator can be designed to meet desired light emitting intensity and direction by integrating micro-structures to the transparent substrate.

主权项

1. A printed surface patterned light diffuser, comprising:
a transparent substrate, a printed image layer on the substrate, and a protection layer on the printed surface, wherein the printed image layer of the printed surface patterned light diffuser substantially consists of an inkjet-printed image and wherein the printed image layer has greater than about 40% color saturation and overall light transmission is between about 15% and about 95%; further, the transparent substrate comprises an optical microstructure on at least one surface where, at least partially, the microstructures manage the direction of transmitted light in order to diffuse the intensity of transmitted light.
