The light guiding prismatic sheet LGP de-couples light, which is fed into the sheet from
the small end, across the wide surface area by the means of integrated prismatic
optics. Light sources may be used as CCFL, linear LED lines or even T5 tubes. The
primary light emitting area has usually a plane surface while the rear surface carries
the micro prism structure. The micro prism structure is not acting as a diffusor, but
uses reflection (direct portion of light ~ 60%) and refraction (indirect portion of light ~
40%) with prism structures. The direct portion of light is usually also de-glared.
Without light fed in from the edges, the LGP plate appears almost transparent.
