Hellisøy Lighthouse
Hellisøy Lighthouse ( no, Hellisøy fyr) is a coastal lighthouse in Fedje municipality in Vestland county, Norway. The lighthouse lies on the small island of Hellisøy, just off the southwest coast of the larger island of Fedje. History This tower was built in 1855, making it Norway's second-oldest cast iron lighthouse. It is essentially a copy of the Eigerøy Lighthouse built a year earlier on the southwest coast. The lighthouse was automated in 1992. The lighthouse emits a continuous white light with a more intense flash every 30 seconds. The light sits at an elevation of about above sea level. The tall round cast iron tower is painted red with two narrow white horizontal bands. There is a 3rd order Fresnel lens in the lighthouse that has been in use since 1903. The lens puts out a light with an intensity of 960,000 candela which can be seen for up to .

Coastal 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 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fedje
Fedje is an island municipality in the Nordhordland region of Vestland county, Norway. The administrative centre of the municipality is the village of Fedje. The traditional economic activity of the inhabitants is fishing. The municipality is the 354th largest by area out of the 356 municipalities in Norway. Fedje is the 350th most populous municipality in Norway with a population of 502. The municipality's population density is and its population has decreased by 12.8% over the previous 10-year period. The municipality consists of the main island of Fedje which is also surrounded by about 125 smaller islands and rocks mostly north of the main island. The name ''Fedje'' applies both to the main island, the main village, and to all the islands and rocks as a whole municipality. In 2016, the chief of police for Vestlandet formally suggested a reconfiguration of police districts and stations. He proposed that the police station in Fedje be closed.

Vestland
Vestland is a county in Norway established on 1 January 2020. The county is located in Western Norway and it is centred around the city of Bergen, Norway's second largest city. The administrative centre of the county is the city of Bergen, where the executive and political leadership is based, but the County Governor is based in Hermansverk. The county is one of two counties in Norway that have Nynorsk as their official written language form (the others are neutral as to which form people use). Vestland was created in 2020 when the former counties of Hordaland and Sogn og Fjordane (with the exception of Hornindal municipality, which became part of Volda municipality in Møre og Romsdal county) were merged. History Vestland county is a newly created county, but it has been inhabited for centuries. The area was made up of many petty kingdoms under the Gulating during the Middle Ages. The northern part was the known as ''Firdafylke'' (now the Fjordane region; Nordfjord-Sunnfjord), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Eigerøy Lighthouse
Eigerøy Lighthouse ( no, Eigerøy fyr) is a coastal lighthouse located at the small island of Midbrødøya which is located immediately west of the island of Eigerøya in Eigersund municipality in Rogaland county, Norway. It was established in 1854 and automated in 1989. This was Norway's first cast iron lighthouse, and its success encouraged the building of many more on the Norwegian coastline. The light sits at an elevation of above sea level, sitting atop a tall tower. The light emits three white flashes every 30 seconds. The light uses a 1st order Fresnel lens and produces a 3,905,000-candela light. The light can be seen from all directions for up to . The tower is attached to a 2-story service building. The lighthouse is painted red with one white horizontal band. The lighthouse was automated in 1989 and it remains under the control of the Kystverket. There are a limited number of tours available. It is accessible by road and the tower is open for touring on Sunday ... [...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.

Candela
The candela ( or ; symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. The word ''candela'' is Latin for ''candle''. The old name "candle" is still sometimes used, as in ''foot-candle'' and the modern definition of ''candlepower''.

Lighthouses In Norway
The coast of Norway is 100,915 km long and there have been a total of 212 lighthouses along it, but no more than 154 have ever been operational at the same time. The first, Lindesnes Lighthouse, opened in 1655; the newest Lighthouse, Anda, was finished in 1932. The first Lighthouses were private operations, but in 1821 the government made the Channel and Harbor Inspector responsible for Lighthouses in Norway. A dedicated Lighthouse Administration was set up in 1841. The Lighthouses are today mostly automated and since 1974, run by the Norwegian Coastal Administration. Two lightvessels had been operated along the Norwegian coast. "Enigheden" off Ålesund from 1856 vas replaced with Lepsøyrev Lighthouse in 1879, and "Ildjernsflu" moored off Nesodden from 1914 until it was scrapped in 1968. This list, while not complete, is sorted by location along the shipping lane from the border with Sweden in the south to Russia in the northeast. The Norwegian Coastal Administration main ...
