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] |
Rogaland
Rogaland () is a Counties of Norway, county in Western Norway, bordering the North Sea to the west and the counties of Vestland to the north, Telemark to the east and Agder to the east and southeast. As of 1 January 2024, it had a population of 499,417 people. The administrative centre of the county is the Stavanger (city), city of Stavanger, which is the third largest city in Norway. Etymology ''Rogaland'' is the region's Old Norse name, which was revived in modern times. During Denmark–Norway, Denmark's rule of Norway the county was named ''Stavanger amt (subnational entity), amt'', after the large city of Stavanger, and this name continued to be used until 1919. The first element in the name ''Rogaland'' is the plural genitive case of ''rygir'', probably referring to the name of an old Germanic peoples, Germanic tribe (see Rugians). The second element is ''land'' which means "land" or "region". Coat of arms The coat of arms is modern; it was granted on 11 January 1974. ...

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 ...

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 ...

Eigerøya
Eigerøya is an island in Eigersund municipality in Rogaland county, Norway. The island lies just off the mainland coast in the town of Egersund. The highest point on the island is the tall ''Varden''. The U-shaped island is divided into two parts by the ''Lundarviga'' bay. The northwestern (smaller) side of the island is called ''Nordre Eigerøya'' and the larger side on the southeast is called ''Søre Eigerøya''. Eigerøya is separated from the mainland by a narrow long strait. The Eigerøy Bridge crosses the strait and connects Eigerøya to the mainland.

Store Norske Leksikon
The ''Great Norwegian Encyclopedia'' (, abbreviated ''SNL'') is a Norwegian-language online encyclopedia. It has several subdivisions, including the Norsk biografisk leksikon. The online encyclopedia is among the most-read Norwegian published sites, with up to 3.5 million unique visitors per month. Paper editions (1978–2007) The ''SNL'' was created in 1978, when the two publishing houses Aschehoug and Gyldendal merged their encyclopedias and created the company Kunnskapsforlaget. Up until 1978 the two publishing houses of Aschehoug and Gyldendal, Norway's two largest, had published ' and ', respectively. The respective first editions were published in 1906–1913 (Aschehoug) and 1933–1934 (Gyldendal). The slump in sales of paper-based encyclopedias around the turn of the 21st century hit Kunnskapsforlaget hard, but a fourth edition of the paper encyclopedia was secured by a grant of ten million Norwegian kroner from the foundation Fritt Ord in 2003.

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] |

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 ...
