LED Full Matrix VMS

LED Full Matrix VMS

applications: dynamic traffic management on highways, traffic guidance in urban areas, warning ahead of work zones, lane control ahead of tunnels and lane assignment inside tunnels, parking lot uidance, traffic calming, etc. Especially, a combination of different colors and sizes make these signs extremely versatile.

Dianming's variable message sign is certified by the Italian Lab (EU Notified Body) - ISTITUTO GIORDANO, according to the EN12966 standards. All displays provide brilliant legibility, high energy efficiency and outstanding LED luminosity. The patented design of optical lens maximize the effective luminance of LED with best beam angle. A wide range of variable message signs can be customized according to different project requirements.

Secondary Optical Lens De sign


The design of Dianming's optical lens is able to focus the light which comes from wide angle (120 degree) of LEDs into narrow angle to be easily read by road users, meanwhile the luminous efficacy got improved and the electric current for LEDs is reduced. As a result, it extends the life span of the VMS as well as energy-saving.
Modular optical lens design means convenient for assembly, maintenance and waterproof. High quality material of optical lens contribute UV-resistance and high light transmittance. The design in honeycomb bead surface is helpful to reduce the glare from sunshine and street light.

Low Reflection Design


The surface of Dianming's VMS applies the unique matte abrasive structure which will create a diffuse reflection to the sunlight; thus the brightnessreflection from front surface of the VMS is reduced.

The optical lens of Dianming's VMS applies the internal light absorption design which will decrease the external light reflection on the lens, so the brightness reflection of the VMS is ulteriorly reduced.

With the matte abrasive surface and the internal light absorption design on lens, the contrast ratio of Dianming's VMS can reach as high as 20:1 in white color, under the external illumination at 40000 lux.

 

 

Smooth Surface Design


Besides traditional VMS structures which use visor design on the surface to increase the contrast ratio, Dianming also produce European style VMS, which its surface with optical lens is more smooth, thus no dust or snow will stay on the VMS surface. The display content on the VMS will be clear and complete all the time.

Font Infinite Zooming


Compare with matrix font, normal matrix font only can display fixed size font, i.e. 16×16, 24×24, 32×32, 48×48, but since we use windows vector font, font can be continuously variable among 1-72, in which we call font infinite zooming. Additionally, some special size fonts are also available without customization.(MULTI-LANGUAGES, various sizes fonts)

Waterproof performance
1. The cabinet seams are
continuous welded.
2. Automotive grade gasket on cabinet doors to prevent leakage.


 

The whole VMS cabinet is made with thick aluminium plate. With overall welding technique, the cabinet is strong and smooth. The surface of the VMS can be self-cleaned through the rain while no visor is necessary on the front of the VMS.
