Hellisøy Lighthouse
Hellisøy Lighthouse () 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 The candela (symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), 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 the advent of much cheaper, more sophisticated, and more 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 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 promontory, prom ...

Fedje
Fedje is an island municipality in the Nordhordland region of Vestland county, Norway. The administrative centre of the municipality is the Fedje (village), 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 513. The municipality's population density is and its population has decreased by 9.8% over the previous 10-year period. The municipality consists of the main Fedje (island), 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 Counties of Norway, county in Norway. The county is located in Western Norway, and its administrative centre is Bergen, where the executive and political leadership is based. The County governor (Norway), County Governor is based in Hermansverk. Vestland is one of two counties in Norway that have Nynorsk as their official written language form. Vestland was created on 1 January 2020, when the former counties of Hordaland and Sogn og Fjordane were merged. History Vestland county is a newly created county, but it has been inhabited for millennia. The area was made up of many petty kingdoms under the Gulating during the Middle Ages. The northern part was then known as ''Firdafylke'' (now the Fjordane region; Nordfjord-Sunnfjord), the central area was known as ''Sygnafylke'' (now the Sogn region), and the southern part was known as ''Hordafylke''. In the early 16th century, Norway was divided into four ''len''. The Bergenhus len was headquartered in Bergen and encompa ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: Cast iron#White cast iron, white cast iron has its carbon combined into an iron carbide named cementite, which is very hard, but brittle, as it allows cracks to pass straight through; Grey iron, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and Ductile iron, 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 iron, malleable cast irons. With its relatively low melting point, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eigerøy Lighthouse
Eigerøy Lighthouse () 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 Sundays in July. See ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens (optics), lens which reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections. The simpler Dioptrics, dioptric (purely refraction, refractive) form of the lens was first proposed by Georges-Louis Leclerc, Comte de Buffon, and independently reinvented by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. The Catadioptric system, catadioptric (combining refraction and reflection) form of the lens, entirely invented by Fresnel, has outer Prism (optics), prismatic elements that use total internal reflection as well as refraction to capture more oblique light from the light source and add it to the beam, making it visible at greater distances. 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 ...

Candela
The candela (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 luminous efficiency function, the model of the sensitivity of the human eye to different wavelengths, standardized by the CIE and ISO. 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''. Definition The 26th General C ...

Lighthouses In Norway
The coast of Norway is 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 Lighthouse, 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 was 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 mai ...
