As the leading Night Scan Light Tower supplier, we’ll talk about the development history of the light tower.
Construction process
In about 270 B.C., Ptolemy II appointed the Greek architect stratus of videos to build the world's first light tower at the eastern end of Faros Island, which can not only guide the ships entering Alexandria but also become a huge symbol of the prominent reputation of the revived Egyptian monarch. Faro's light tower has thus become one of the seven wonders of the ancient world.
The ancient Romans built a series of light towers, thus creating the earliest light tower network system. The earliest light tower in this system was built in AD 50. The Roman Emperor Claudius ordered the construction of a light tower in the Roman port city of Ostia. The port originally had a waste wooden ship 320 feet long and 65 feet wide. The ship was built with stones and adhesives to form an artificial island. The light tower was built on the island, with a total of four floors. The Ostia light tower remained until the 15th century.
Later, Arabs, Indians, and Chinese also learned this method to ensure the safety of ships at sea and built light towers on their surrounding coasts.
Modern tower lamp
From the end of the 18th century to the 19th century, luminous devices with mirrors, lens light towers, power light towers, and so on appeared one after another.
The first gas flashlight tower was built in 1906. As modern navigation equipment has been very advanced, the number of man-made light towers has been greatly reduced, leaving only 1500 light towers still operating in the world.
The light source of the light tower is called a "lamp" (whether electric or oil fuel), which has been lit by an open fire for a long time, and then replaced by candles.
In 1781, the use of cylindrical bulbs and parabolic reflectors began in Europe.
In the United States, whale oil was used as a solid light source wick. In 1810, Winslow Lewis introduced a cylindrical wick lamp and a parabolic reflector system.
In the early 1850s, Americans began to use rapeseed oil instead of whale oil as fuel. In the mid-1950s, it was replaced by lard.
Since the 1870s, kerosene gradually began to replace lard, and all the replacement was completed by the end of the 1980s.
At the beginning of the 20th century, electricity and calcium carbide acetylene began to replace kerosene, and further developed by Darren light, so that the tower lamp can be automatically lit at dusk and automatically extinguished at dawn.
