St Anthony's Lighthouse
St Anthony's Lighthouse ( kw, Golowji Entenin) is the lighthouse at St Anthony Head, on the eastern side of the entrance to Falmouth harbour, Cornwall, UK. The harbour is also known as Carrick Roads and is one of the largest natural harbours in the world. History The lighthouse was designed by James Walker and built in 1835 by Olver of Falmouth, for Trinity House and the original light came from eight Argand oil lamps mounted on a revolving frame. The light was seen to flash once every twenty seconds. In 1865 an additional lamp and reflector were installed 'in the living room of the principal keeper' which shone a fixed light through a square window in the direction of a dangerous cluster of rocks known as The Manacles. (At the time the principal keeper and his family lived in the tower itself, while the assistant lived in the cottage, linked to the lighthouse by a covered way). After 1903 this subsidiary light was instead shown from a separate 'hut' from the tower itself. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

First Order 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 reduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouses Completed In 1835
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 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fraggle Rock
''Fraggle Rock'' (also known as ''Jim Henson's Fraggle Rock'' or ''Fraggle Rock with Jim Henson's Muppets'') is a children's musical fantasy comedy puppet television series about interconnected societies of Muppet creatures, created by Jim Henson. An international co-production of Canada, the United Kingdom and the United States, ''Fraggle Rock'' was co-produced by British television company Television South (TVS), the Canadian Broadcasting Corporation (CBC), U.S. pay television service Home Box Office (HBO), and Henson Associates. Unlike ''Sesame Street'', which had been created for a single market and only later adapted for international markets, ''Fraggle Rock'' was intended from the start to be an international production, and the entire show was constructed with this in mind. At least four different versions of the human "wraparound" segments were produced separately to air in different countries. Following the success of the ''Fraggle Rock: Rock On!'' shorts which aire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fog Horn
A foghorn or fog signal is a device that uses sound to warn vehicles of navigational hazards such as rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used in relation to marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rock outcrops, shoals, headlands, or other dangers to shipping. Description All foghorns use a vibrating column of air to create an audible tone, but the method of setting up this vibration differs. Some horns, such as the Daboll trumpet, used vibrating plates or metal reeds, a similar principle to a modern electric car horn. Others used air forced through holes in a rotating cylinder or disk, in the same manner as a siren. Semi-automatic operation of foghorns was achieved by using a clockwork mechanism (or "coder") to sequentially open the valves admitting air to the horns; each horn was given its own timing characteristics to help mariner ...

Flashing Light
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, " ...

Electric Light
An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting. Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet cap. The three main categories of electric lights are incandescent lamps, which produce light by a filament heated white-hot by electric current, gas-discharge lamps, which produce light by means of an electric arc through a gas, such as fluorescent lamps, and LED lamps, which produce light by a flow of electrons across a band gap in a semiconductor. Before electric lighting became common in the early 20th century, people used candles, gas lights, oil lamps, and fires. Vasily Vladimirovich Petrov developed the first persistent electric arc in 1802, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
