Digital EN12966 Outdoor LED Message Boards Variable Road Signs
variable message sign single color module traffic safety digital outdoor LED display
LED guidance screen is the product of the combination of intelligent transportation system and LED display technology. Its main role is to make real-time or delayed information transmission and road guidance for incoming traffic flow, and to intervene and manage traffic flow through advance information sharing. LED guidance screen has LED display of intelligence and operability, with the intelligent system of traffic guidance screen, can timely put forward early warning, road guidance and notification notification, etc.
Product Features
1, Use of sophisticated large-scale integrated chip high-speed serial transmission network alternative to discrete parallel transmission chip, reducing the complexity ofthe transmission display, reducing the complexity of the control system to improve the stability of the product.
2, Using the network cable to transmit data to reduce the screen body inside the transmission cable, greatly improve the stability of the display.
3, Using a common network data transmission technology, improve gradation display variable message signs, information boards enable a better display.
4, Using a common network data transmission technology, in favor of compatibility and product upgrading. Help to improve the response speed of the system variable message signs.
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.
