solar powered traffic sign

But when the two semiconductor connected to form a "PN junction" between them. When the current through the wire on the chip, solar powered traffic sign the electronics will be pushed P area, electron hole recombination, and will be issued in the form of photon energy in the P area, this is the principle of single led solar waring light. The wavelength of light determines the color of the light is determined by the decision of the material to form a PN junction.

traffic direction signs

Modern steel lightship is a small boat, equipped with fog number, traffic direction signs radio beacons and navigation in bad weather manipulation to maintain the level of light beam devices. The role of lighthouse signal is emitted recognizable day and night at sea for vessels measuring position and provide hazard warning to ships. led beacon signal includes two fixed signal and the flash signal, the signal is fixed within a certain range directional lights emit red or green light, a sense of direction for the ship; flash signal is used as an identification signal.

Solar panels subjected to rolling wheel wear every day, cardboard traffic signs if the strength is not enough, easy to wear flowers, thereby affecting the efficiency of solar cells.
