Solar Synchronous Contour Specificatio On the highway night vision is poor, the road profile is not clear enough. Driving speed is too fast, in order to avoid or reduce the occurrence of traffic accidents. Our company has developed many years of experience to develop synchrotron LED lamp outline standard, which is characterized by: luminous intensity, visual distance, through the GPS technology to achieve solar contours at night synchronized flashing light, no distance limit, as long as the GPS satellite can receive The signal can be synchronized, better outline the outline of the road, the simple installation of the construction.         Technical indicators: 1, a variety of energy storage components: 3.6V nickel-metal hydride batteries 800mA, 3.7V lithium particles 800mA, lithium iron phosphate battery 3.2V-800MAH, charge and discharge times> 1000; 2, solar rechargeable batteries: monocrystalline silicon 5V 70MA 3, working time: in the standard li...
