The commonly used in a number of internal and external applications.It worth noting that these products are thinner and have the ability to illuminate a larger surface area.Moreover is efficient, since they reduce the costs of installing and running costs.In fact, the progress of LGP technology, sign boards which are as large as 1.5m to 2.3m can be illuminated conveniently.

To improve their effectiveness, it is also equipped with sign boards for sale.This implies basically that whenever the light emitted by the source travels through the panel in a controlled manner into the interior of LGP.
