Amelia Island Light
The Amelia Island Light is the oldest existing lighthouse in the state of Florida in the United States. It is located near the northern end of Amelia Island in the northeastern part of the state. Its light marks St. Marys Entrance, the inlet leading to St. Marys River, the Cumberland Sound and the harbor of Fernandina Beach, Florida along the Amelia River. The white light flashes every ten seconds which turns red from 344° to 360° when covering the shoal water in the vicinity of Nassau Sound. The lighthouse is listed as number 565 in the United States Coast Guard (USCG) light list. History The lighthouse was built in 1838 using materials taken from the former lighthouse (the predecessor of Little Cumberland Island Light) on the southern tip of Cumberland Island in Georgia just north of the inlet, which had been built in 1820. The brick tower was originally tall placed on a hill. In 1881, a lantern was installed on the tower increasing the tower height to with the foca ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The '' catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouses On The National Register Of Historic Places In Florida
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Lighthouses In The United States
This is a list of lighthouses in the United States. The United States has had approximately a thousand lights as well as light towers, range lights, and pier head lights. Michigan has the most lights of any state with over 150 past and present lights. Lighthouses that are in former U.S. territories are not listed here. Most of the lights in the United States have been built and maintained by the Coast Guard (since 1939) and its predecessors, the United States Lighthouse Service (1910–1939) and the United States Lighthouse Board (1852–1910). Before the Lighthouse Board was established, local collectors of customs were responsible for lighthouses under Stephen Pleasonton. As their importance to navigation has declined and as public interest in them has increased, the Coast Guard has been handing over ownership and in some cases responsibility for running them to other parties, the chief of them being the National Park Service under the National Historic Lighthouse Preservatio ...

The first tower was built around 1737. Archival records are inconclusive as to whether the Spanish used the tower as a lighthouse. While it seems likely, not enough has been gathered to place it as a fact. :B. The tower was washed away in 1851. :C. In 1960, the lighthouse was replaced with a skeletal steel tower. The old structure moved multiple times as a private residence before it was returned to St. Joseph Bay in 1979. While the old light remains a private residence, its current owner has restored its former appearance with a rebuilt lantern room.

Brick
A brick is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term ''brick'' denotes a block composed of dried clay, but is now also used informally to denote other chemically cured construction blocks. Bricks can be joined using mortar, adhesives or by interlocking them. Bricks are usually produced at brickworks in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. ''Block'' is a similar term referring to a rectangular building unit composed of similar materials, but is usually larger than a brick. Lightweight bricks (also called lightweight blocks) are made from expanded clay aggregate. Fired bricks are one of the longest-lasting and strongest building materials, sometimes referred to as artificial stone, and have been used since circa 4000 BC. Air-dried bricks, also known as mud-bricks, have a history older than fired bricks, and have an addit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
