Mystic Seaport Light
Mystic Seaport Light is a lighthouse at the south end of Mystic Seaport, upriver from Noank, Connecticut. The light is a two-story white shingled structured topped with a glass-enclosed lantern and is a replica of the 1901 Brant Point Light. The Mystic Seaport Light was designed by William F. Herman Jr. and constructed in 1966. It was formally dedicated on August 31, 1967, but remained unlit due to active navigational regulations imposed by the United States Coast Guard. The Mystic Seaport light is now an active light, but not an official aid to navigation. The structure was used as an example of a lighthouse for Mystic Seaport visitors, but was not part of an exhibit until a 2008 renovation. The interior of the lighthouse was equipped with five LCD televisions to display two short educational films that highlight the history and architectural diversity of American lighthouses.

Lighthouse
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] |
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] |

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 Preservation ...

List Of Lighthouses In Connecticut
The U.S. state of Connecticut has fourteen active lighthouses in the state, two of which are maintained as private aids; six are standing but inactive. Another was destroyed after its deactivation. The earliest lighthouse in the state was erected in 1760, but that tower, the first New London Harbor Light, was replaced in 1801, and its successor is the oldest surviving light in Connecticut, as well as the tallest. The last officially recognized lighthouse in the state, the Avery Point Light, was constructed in 1943, but was not lit until the following year. The Mystic Seaport Light, constructed in 1966, is a functioning replica housed with a historic Fresnel lens; it is classified as an unofficial and non-navigational aid.

LCD TV
Liquid-crystal-display televisions (LCD TVs) are television sets that use liquid-crystal displays to produce images. They are, by far, the most widely produced and sold television display type. LCD TVs are thin and light, but have some disadvantages compared to other display types such as high power consumption, poorer contrast ratio, and inferior color gamut. LCD TVs rose in popularity in the early years of the 21st century, surpassing sales of cathode ray tube televisions worldwide in 2007. Sales of CRT TVs dropped rapidly after that, as did sales of competing technologies such as plasma display panels and rear-projection television. History Early efforts Passive matrix LCDs first became common as portable computer displays in the 1980s, competing for market share with plasma displays. The LCDs had very slow refresh rates that blurred the screen even with scrolling text, but their light weight and low cost were major benefits. Screens using reflective LCDs required no internal ...

Nantucket Lightship Basket
Nantucket Lightship Baskets are a type of basket originating, in the 19th century on Nantucket Island lightships. Lightship baskets are all made from rattan and wood, have an odd number of staves, a solid wooden base, a nailed and lashed rim, a rattan weaver, and are woven over a mould. Oak, pine, and ash are the most traditional type of wood used on baskets, but today many other types are utilized, such as cherry and ebony. Often modern Lightship Baskets incorporate multiple types of wood. History Origin Baskets began being made on Nantucket Island by Native Americans of the Wampanoag Nation; these were generally of the splint type, and bear little resemblance to Nantucket Lightship Baskets. Nevertheless, these early baskets may have inspired later basket makers on Nantucket and aboard the lightships. The earliest form of basket made by white settlers on Nantucket, originated on whaleships in the early 1800s. These baskets were made free form (without a mould) and are thu ...

Nantucket, Massachusetts
Nantucket () is an island about south from Cape Cod. Together with the small islands of Tuckernuck and Muskeget, it constitutes the Town and County of Nantucket, a combined county/town government that is part of the U.S. state of Massachusetts. It is the only such consolidated town-county in Massachusetts. As of the 2020 census, the population was 14,255, making it the least populated county in Massachusetts. Part of the town is designated the Nantucket CDP, or census-designated place. The region of Surfside on Nantucket is the southernmost settlement in Massachusetts. The name "Nantucket" is adapted from similar Algonquian names for the island, but is very similar to the endonym of the native Nehantucket tribe that occupied the region at the time of European settlement. Nantucket is a tourist destination and summer colony. Due to tourists and seasonal residents, the population of the island increases to at least 50,000 during the summer months.
