Light Guide Panel (LGP) is new backlit unit technology. A backlight used in a liquid crystal display or lighting panel includes light source for emitting light. The secret to the slim profile of edge light signs is the location of the light source and the innovation design of the optical light plate. The LED or fluorescent tubes are mounted on the edge of the light plate, rather than behind as in conventional signs, which significantly reduced the thickness of the signs. The light travels through the sign with the help of the laser-dotting pattern, v-cutting pattern or digital printed dot screen.

The size and density of the dots on the plate vary according to their distance to the fluorescent tubes. This pattern brings out a very bright and even distribution of light across the entire plate.

LGP is made of light-transmittable acrylic resin, and the light source is located on edges of the LGP. The LGP guide light and scatter the light emitted from the light source through optical path with the help of a designed pattern.

Comply with the criterion of brightness and evenness of the advertisement light box totally. The brightness and evenness of each dimension of the light panel is ensured, even the evenness of the panel width of 1.2 meter is not lower than 70%. And the average luminosity of 35 watt T4 strip lamp will reach minimum 1200LUX.
