The lighthouse tower is twelve metres tall, the height of the light above the high-water mark is . The light is positioned to give a waypoint for vessels passing along the English Channel coast. Originally the light was illuminated by a Douglass multi-wick mineral oil burner, set within a large (First order Fresnel lens, first order) revolving 14-panel Dioptric lens, dioptric optic by Chance Brothers, Chance Brothers & Co. It was the first example of a significant new desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swanage
Swanage () is a coastal town and civil parish in the south east of Dorset, England. It is at the eastern end of the Isle of Purbeck and one of its two towns, approximately south of Poole and east of Dorchester. In the 2011 census the civil parish had a population of 9,601. Nearby are Ballard Down and Old Harry Rocks, with Studland Bay and Poole Harbour to the north. Within the parish are Durlston Bay and Durlston Country Park to the south of the town. The parish also includes the areas of Herston, just to the west of the town, and Durlston, just to the south. The town, originally a small port and fishing village, flourished in the Victorian era, when it first became a significant quarrying port and later a seaside resort for the rich of the day. Today the town remains a popular tourist resort, this being the town's primary industry, with many thousands of visitors coming to the town during the peak summer season, drawn by the bay's sandy beaches and other attractions.

Reflective Prism
An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are ''not'' prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides. Not all optical prisms are geometric prisms, and not all geometric prisms would count as an optical prism. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, acrylic and fluorite. A dispersive prism can be used to break white light up into its constituent spectral colors (the colors of the rainbow) as described in the following section. Other types of prisms noted below can be used to reflect light, or to split light into components with different polarizations. Types Dispersive ''Dispersive prisms'' are used to break up light into its constituent spectral colors be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourist Attractions In Dorset
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVID-19 ...

Lighthouses Of The English Channel
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] |

LED Lamp
An LED lamp or LED light bulb is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and can be significantly more efficient than most fluorescent lamps. The most efficient commercially available LED lamps have efficiencies of 200 lumen per watt (Lm/W). Commercial LED lamps have a lifespan many times longer than incandescent lamps. LED lamps require an electronic LED driver circuit to operate from mains power lines, and losses from this circuit means that the efficiency of the lamp is lower than the efficiency of the LED chips it uses. The driver circuit may require special features to be compatible with lamp dimmers intended for use on incandescent lamps. Generally the current waveform contains some amount of distortion, depending on the luminaires’ technology. The LED lamp market is projected to grow from US$75.8 billion in 2020 and increasing to US$160 billion in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harwich
Harwich is a town in Essex, England, and one of the Haven ports on the North Sea coast. It is in the Tendring district. Nearby places include Felixstowe to the north-east, Ipswich to the north-west, Colchester to the south-west and Clacton-on-Sea to the south. It is the northernmost coastal town in Essex. Its position on the estuaries of the Stour and Orwell rivers, with its usefulness to mariners as the only safe anchorage between the Thames and the Humber, led to a long period of civil and military maritime significance. The town became a naval base in 1657 and was heavily fortified, with Harwich Redoubt, Beacon Hill Battery, and Bath Side Battery. Harwich is the likely launch point of the ''Mayflower'', which carried English Puritans to North America, and is the presumed birthplace of ''Mayflower'' captain Christopher Jones. Harwich today is contiguous with Dovercourt and the two, along with Parkeston, are often referred to collectively as ''Harwich''. History The tow ...

Tannoy
Tannoy is a British manufacturer of loudspeakers and public address systems. Founded by Guy Fountain in London in 1926 as the Tulsemere Manufacturing Company, today the company is part of the Music Tribe group of brands. History Tannoy Ltd is a British manufacturer of loudspeakers and public address (PA) systems. The company was founded by Guy Fountain in London, England, as Tulsemere Manufacturing Company in 1926, and moved to Coatbridge, Scotland in the 1970s. Tannoy's image is particularly linked to both studio monitors as well as its Prestige range of home speakers. Prestige speakers use Dual Concentric cone speakers and are easily recognisable by their "vintage" design. Tannoy is notable for its 'Dual Concentric' speaker design, which places the tweeter behind the centre of the medium or bass driver. "Dual Concentric" is a trademark although Tannoy is not the only speaker manufacturer to design coaxial speakers. In 2002, Tannoy was acquired by TC Group, and TC Group was s ...
