Illumination control

摘要

The methods, devices, and/or compositions described herein can be used to reduce variations, such as spatial and temporal variations, in luminance intensity. Luminance variation is reduced by varying some aspect of transmittance with respect to the intensity of light.

主权项

1. A diffusion lens for a light source, the lens comprising an adjustable light diffusing layer, wherein the adjustable light diffusing layer is configured so that transmittance properties of the adjustable light diffusing layer can be variably adjusted during operation of a viewable device, such that transmittance through the adjustable light diffusing layer varies inversely with respect to an intensity of light impacting the adjustable light diffusing layer so that luminance variation is reduced over the surface of the lens.
