A Brief of Sansi Variable Message Sign Products

Back

2021/08/25

Any VMS (variable message sign) products will be exposed to harsh outdoor environments once installed such as rain, snow, wind and sandstorms, etc. This requires the products to have high visual penetrability, effective brightness, optimal contrast ratio and durable IP Level. Display screens need to have a reliable performance to stand various weather conditions.

SANSI has been leading the standards in VMS product research and development since 1993. SANSI Highway information screens have much higher reliability than regular products, with L3 brightness, R3 contrast ratio & higher IP levels. They are energy efficient by reducing power consumption, heat dissipation significantly improved. SANSI VMS products could be adopted in any ITS applications and offer industrial-level of reliability, legibility, and credibility.

To guarantee the best quality of products, Sansi applies strict quality control measures in all aspects of the manufacturing process, all those make it a versatile solution for modern smart traffic.

 

EN12966 Certified


SANSI LED information screens offer a highly configurable, adaptable and flexible solution for a wide range of application scenarios. Featuring the latest technology and EN12966 certified by meeting the following criteria through all round tests: visual performance, physical performance, structural performance, electrical requirements, electromagnetic compatibility; which is of great benefit to improve the access standards and to ensure the quality of traffic information screens.

Outstanding Optical Performance


SANSI LED screen optical lens is a patented product. SANSI optical lenses increase visual accessibility and produce uniform light distribution. The unique structure strictly keeps the light within the angle of 0°~-15°, which avoids any light interference into the driver’s viewing angle.

In general, traditional lenses will have the similar luminance as in the left image, symmetrical distribution, low efficiency and heavy light pollution. The right image shows how the SANSI lens has polarized distribution, higher efficiency and no light pollution.

The unique surface structure of SANSI lens absorbs a significant amount of sunlight, which eliminates the interference of sunlight while sustaining the performance of the LED screens

Compared with traditional lenses, the smooth surface of SANSI lens enables a better color mix of the LED, almost without the chromatic aberration of white light.

SANSI LED screen module consists of multiple layers, which avoids interference of light from different LED chips and thus it ensures a better visual performance.

Superior Cabinet Structure


VMS Cabinet front cover has a spraying treatment with a special coating and technical design of the surface texture. The cabinet surface has a unique matte treatment to reduce sunlight reflection and to increase the contrast ratio, which ensures better display performance.The edge-free design keeps the module from being easily covered by snow or dust, avoiding light loss from potential snow cover; and keeps the cabinet surface safe from erosion.
