<p>The present invention relates to signs using green energy and, more specifically, to the signs which are configured to easily confirm characters by emitting a back surface light source from the back surface of an outer surface plate of signs forming characters. The signs are equipped with a film light emitting body to emit back surface light source from the back surface of characters formed on the signs and signs which are composed of a protective cover, a cover and a base plate being sequentially deposited on the back surface of the film light emitting body. Additionally, a solar cell module and a wind power device can be disposed on the signs, and characters formed on the signs can be more easily and evidently identified using signs deposited with film light emitting body by providing signs which can operate a closed circuit imaging apparatus operated by the power supply. Traffic accidents can be greatly prevented since a film light emitting body can be clearly identified even if the back surface light source is not emitted, so characters on the signs can be preliminarily recognized even if characters on the signs are not ascertained by the light of vehicle headlights or sunlight. By using solar light and wind power for power source to operate a film light emitting body disposed on the signs, thereby incorporating signs using green energy, a hybrid concept without adding additional power supply is realized.</p> |
