1. The whole has four parts, respectively for the reflective film marking plate, light source system, control system, power supply system. Full assurance marks long-term stable work. 2. The light source uses nanometer alloy light guide plate technology, the overall luminous part of the brightness is uniform. 3. Back light source/side light source technology, photoelectric conversion efficiency is high, low power consumption.Full penetration mark power consumption is 20W/m. 4. Based on reflective film technology, photoelectric technology, intelligent control technology, sensor technology.By marking the main information surface light source luminous way, to road users all weather, wisdom The road traffic sign which can transfer information is the future road traffic information Intelligent carrier。 5.Full penetration sign has long visual distance, soft light, and clear and accurate information transmission.Transfer function, while matching city beautification, lighting.
