A lighting lighthouse is a tall tower shaped building, with lighting equipment installed at the top of the tower. The location should be prominent, and attention should be paid to its specific architectural appearance, making it easy for ships to distinguish and becoming one of the higher points in the port. Due to the curved surface of the Earth, the tower body must have sufficient height so that its brightness can be observed by distant ships. The normal line of sight is 15-25 nautical miles, but the lighting should not be too high to avoid being covered by clouds and mist at high altitudes. According to the size of the lighthouse and the characteristics of its location, lighthouses can be guarded or unguarded, and important lighthouses should be guarded. In the ancient lighting lighthouses of the past, kerosene lamps were used as the light source, and a lens system was manually operated by the lighthouse operator to rotate and concentrate the light. The lens system often floated in water to avoid friction. Modern lighting towers are equipped with electric lights and mainframes that are powered by external sources, as well as diesel driven generators to operate and provide electricity for people's daily lives. Some products are powered by solar energy.
As a symbol of a place, it not only makes people feel majestic and spectacular, but also has many powerful functions that guide us forward. So, what are the components of its structure? Below is an introduction for you.
1. The tower body and lighting lighthouse are composed of lamps and tower body. It can be constructed from various building materials, mainly to adapt to and resist harsh natural conditions such as wind and waves, in order to maintain its stability and durability. The height of the body should meet the requirements of the light range.
2. Luminaires and appliances are composed of two fundamental parts: light emitters and radiators. Modern lighthouses mainly use electricity as their light source. The center of the light emitting machine is located at the focal point of the condenser lens, and the light source emits spherical light that passes through the condenser lens and becomes a parallel beam with a certain diffusion angle. The range of a lighthouse can reach about 30 nautical miles, and its intensity can reach hundreds of millions of candles. It has flashes, fixed lights, and bright and dark lights, with colors including red, white, green, and white. Red and green lights are usually used to indicate obstacles within the light arc.
The significance of lighting a lighthouse is profound. In the past, because it was ignited by flames, it meant hope. In old products, in order to store energy and concentrate light sources, the emitted light was emitted in a horizontal direction, and the line level at the top of the tower remained unchanged. A rotating installation was installed at the top of the tower to ensure that the brilliance could be seen in every direction around.
If we want to enhance brightness, a very large lens is required, which may not even be able to accommodate the weight of the lighting tower. A special type of mirror emerged as a result, whose design greatly reduces the gravity and capacity of the lens while maintaining the focal length spacing. Some tall towers, such as the Cape Wise Lighthouse in Newfoundland and the Macape Tower in Hawaii, use another specially developed Japahadi macro lens by Baos Corporation. In modern automated machines, rotating mirrors distribute very bright light through an omnidirectional system (no longer just collecting more light when the space is large). Among many designs and observation products, people would rather see intermittent but tiny light, so they only briefly emit strong light after the tiny bright spot. These momentary bright lighthouses are arranged as special products that emit distance light.
The above is the introduction about it, hoping it will be helpful to you.
