Light control device

Abstract

Abstract A decorative light control panel for use in conjunction with a light source for simultaneous reduction of glare, masking of the light source and delivery of a light output of a uniform brightness, comprising a transparent sheet having a first surface to receive the incident light from a light source and a second surface opposite to said first surface to emit the light received; said first surface composed of a plurality of spaced light diffusing areas having means to diffuse light incident upon them from the said light source and a plurality of alternating clear light transmitting areas permitting the remaining portions of the incident light to pass through said transparent sheet unimpeded; the light diffusing and light transmitting areas of the said first surface being arranged in decorative patterns; said second surface provided with arrays of light refractive means; the two opposite said surfaces forming with said transparent sheet an integral unit. The means to diffuse and the means to transmit directly, of the first surface preferably, but not necessarily, are arranged in symmetrical alternating configurations of parallel lines, dots and/or patterns. The refractive means of the second surface preferably are arrays of lenses, prisms and their combinations and are not necessarily correlated in their patterns with the patterns of the areas of the first surface.
