Optical technology

VMS has been designing LED-based signage for over 20 years and in this time we have gained a very high level of expertise in the application of light emitting display technologies.

The CIE 1931 Colour Chart showing traffic singnal colour areas.

Two key factors in the selection of the right product for each application are Colour and Resolution. The colour standards for road signals are defined as areas on the CIE 1931 Colour Chart - as defined in EN 12966.

Sign matrix resolution is governed by international standards which are based on experience gathered over years of deploying variable message signs and many viewing trials.

It is vital to match the correct colour specification and matrix resolution to meet the specific requirements of the sign application. We have made available two presentations which can be downloaded from this page explaining the significance of both these factors.

Optical design is absolutely key to our products and VMS have always ensured it is at the heart of everything we do.

VMS has its own in-house UKAS accredited optical laboratory - the only manufacturer to have such a facility.
