Energy Saving P12mm LED VMS Signs City Road Gantry Information
Variable Message Board Gantry Information Signboard City Road Energy-Saving LED VMS Sign
Dynamic content: These signs can display dynamic content, such as real-time traffic updates, weather alerts, and emergency messages.
Energy efficient: LED technology used in these signs is energy efficient, which reduces operating costs and is more environmentally friendly.
Better contrast ratio
The surface of each optical len is designed with carved strips that could tremendously reduce light reflection.
High stability
Less manual production and component processes, less potential failure rate, bringing the new module up to a new level of stability.
High colour consistency
With a much improved flatness, diode spectrum and brightness are able to remain the same, making the colour more consistent and
content more readble.
Smart monitor
Yaham VMS can activate self-diagnosis and report health status, monitor can identify equipment health status, current message ID,
current operating mode temperature, humidity, etc
Energy-efficient
Industry-leading dual-voltage technology, it can tremendously improve energy efficiency and maximumly lower light
pollution.Technology
--Sleep mode:
YHT-VMS product,in the blank area, only a 10uA current will flow in each channel under sleep mode. A sample calculation for energy
saving is showingas follows. YHT-VMS product will save around 800 times for every single IC driver than general VMS!
--Dual Voltage
Due to lighting chip difference inside, Red/Amber LED has lower threshold voltage to light up than Green/Blue LED. So, we applied
dual voltage channel to drive two types of LEDs. Surplus energy is saved by this technology. Using separate voltage driving board to
achieve energy-saving purpose:specific voltages are applied to different lamps.
Multiple language support: LED VMS signs can display messages in multiple languages, making them useful in areas with diverse populations or for international events.
