The working principle of LED traffic signs

The eye-catching solar logos, daytime solar panels absorb sunlight, converts solar energy into electric energy, led traffic signs  in the energy storage device, in the evening, energy storage devices in the electric energy into light (automatic control through photoelectric switch), to draw the pattern profile of light emitted by LED, communication traffic information.
Early LED traffic signs, is basically a light box, circuit, controller, batteries are arranged in the box body. Its drawbacks: the box is too heavy, the solar panel the solar traffic sign  is too large, is not conducive to the packaging, transport, in the transport process, often causing internal damage; cell and circuit are sealed in a box body, should not be replaced; the box is too large, the seal is difficult to control.
LED traffic signs is based on a single crystal silicon solar cell components for energy, without network support, not subject to geographical constraints, the use is very convenient! It is the use of solar cells to the conversion of sunlight into electricity stored in signs, when night fell, the dim light or rainy weather, the line of sight is not good situation, LED LED traffic signs to automatically start flashing light, especially bright, eye-catching, with strong warning function. Particularly in the led flashing traffic sign field and dangerous areas without power highway, often moving, the active luminescent LED traffic signs reflects the special warning function, the visual distance is a reflective film as 5 times the sign reflective material brand, its dynamic effect is also common sign board which can not be substituted.
