This article presents the innovative 3G technology used in the VMS (variable message signs). The 3G optics is an advanced lenticular solution that allows an effective mixing of three colours (RBG) without the effect of the colour change depending on the viewing angle. This technology is in opposition to the previously used systems with the separated light beam distribution for the red, green and blue colour. The work describes in detail the functional and technical performance of the new VMS technology and summarizes the characteristics of the parameters obtained from the previously used light beam distribution technology. An important element of the study is to present a measures of performance and efficiency associated with the power consumption, light output, light distribution, visibility, legibility, reliability and durability. Particular attention was paid to the evaluation of the VMS optical performance efficiency. In addition, in the presented work were shown examples of the installed 3G VMS, as well as examples of graphic and text messages displayed on 3G signs.
