Road traffic signs appearance and electricity interpretation

Road traffic signs profile are usually square, triangular, rectangular, pattern clear, obvious sign; sign lighting for road traffic signs  flash red, green, yellow and so on, the use of solar power, no pollution, dust, rain; flash mark of the aluminum alloy structure, road traffic signs light tube using ultra bright LED light-emitting tube, safe and reliable, the service life is long; each LED luminous tube is provided with a special lens separate, in order to guarantee the Solar Traffic Sign  luminous tube optical achieve optimum performance, waterproof and has excellent; solar panels in the range of 360 degrees can be arbitrarily rotated, high conversion efficiency, cloudy days can also recharge the battery; road traffic signs by using a single crystal silicon solar plate, at the temperature of 40 DEG C, ensure the normal working load, the output voltage is not less than 12V, the output current is not less than 250mA; the battery at the temperature of 40 DEG C, to ensure the normal work, the capacity fading of not more than 30%; the flash frequency is led flashing traffic sign  min; flash mark working voltage is DC 12V; when the illumination intensity is less than 150K when the flash symbol, can automatically start to work.
