Headlight
A headlamp is a lamp (electrical component), lamp attached to the front of a vehicle to illuminate the road ahead. Headlamps are also often called headlights, but in the most precise usage (language), usage, ''headlamp'' is the term for the device itself and ''headlight'' is the term for the light beam, beam of light produced and distributed by the device. Headlamp performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities: the US National Highway Traffic Safety Administration states that nearly half of all traffic-related fatalities occur in the dark, despite only 25% of traffic travelling during darkness. Other vehicles, such as trains and aircraft, are required to have headlamps. Bicycle lighting, Bicycle headlamps are often used on bicycles, and are required in some jurisdictions. They can be powered by a battery (electricity), battery or a small generator like a bottle dynamo, bottle o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fog Lamp
The lighting system of a motor vehicle consists of lighting and signalling devices mounted to or integrated into the front, rear, sides, and in some cases the top of a motor vehicle. They illuminate the road ahead for the driver and increase the vehicle's visibility, allowing other drivers and pedestrians to see its presence, position, size, direction of travel, and its driver's intentions. Emergency vehicle, Emergency vehicles usually have Emergency vehicle lighting, distinctive lighting equipment to warn drivers and indicate priority of movement in traffic. History Early road vehicles used Oil lamp, fuelled lamps before the availability of electric lighting. The Ford Model T used carbide lamps for headlights and oil lamps for tail lights. It did not have all-electric lighting as a standard feature until several years after its introduction. Dynamos for automobile headlights were first fitted around 1908 and became commonplace in 1920s automobiles. Silent film star Florence L ...

Citroën DS
The Citroën DS () is a Front-mid-engine, front-wheel-drive layout, front mid-engined, front-wheel drive executive car manufactured and marketed by Citroën from 1955 to 1975, in fastback/sedan, wagon/estate, and convertible body configurations, across three series of one generation. Marketed with a less expensive variant, the Citroën ID, the DS was known for its aerodynamic, futuristic body design; unorthodox, quirky and innovative technology, and it set new standards in ride quality, car handling, handling, and braking — thanks to both being the first mass production car equipped with hydropneumatic suspension, as well as disc brakes. The 1967 series 3 also introduced ''directional headlights'' to a mass-produced car.After this feature was first introduced on the 1948 Tucker 'Torpedo', of which 50 were built. Italian sculptor and industrial designer Flaminio Bertoni and the French aeronautical engineer André Lefèbvre styled and engineered the car, and Paul Magès develop ...

Light Beam
A light beam or beam of light is a directional projection of light energy radiating from a light source. Sunlight forms a light beam (a sunbeam) when filtered through media such as clouds, foliage, or windows. To artificially produce a light beam, a lamp and a parabolic reflector is used in many lighting devices such as spotlights, car headlights, PAR Cans, and LED housings. Light from certain types of laser has the smallest possible beam divergence. Visible light beams From the side, a beam of light is only visible if part of the light is scattered by objects: tiny particles like dust, water droplets (mist, fog, rain), hail, snow, or smoke, or larger objects such as birds. If there are many objects in the light path, then it appears as a continuous beam, but if there are only a few objects, then the light is visible as a few individual bright points. In any case, this scattering of light from a beam, and the resultant visibility of a light beam from the side, is known as t ...

Columbia Automobile Company
Columbia was an American brand of automobiles produced by a group of companies in the United States. They included the Pope Manufacturing Company of Hartford, Connecticut, the Electric Vehicle Company, and an entity of brief existence in 1899, the Columbia Automobile Company. In 1908, the company was renamed the Columbia Motor Car Company and in 1910 was acquired by United States Motor Company. A different Columbia Motors existed from 1917 to 1924. Electric models The 1904 'Columbia Brougham' was equipped with a tonneau. It could seat 4 passengers and sold for . Twin electric motors were situated at the rear of the car. Similar 'Columbia' coupes, 'Columbia Hansom' cabs, or hansoms, were also produced for the same price. They could achieve . A 'Columbia Victoria Phaeton' was priced at , but was based on the same design. The 'Columbia Surrey' and 'Columbia Victoria' were more traditional horseless carriages. Both used the same power system as the larger cars, with tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth Of Nations
The Commonwealth of Nations, simply referred to as the Commonwealth, is a political association of 56 member states, the vast majority of which are former territories of the British Empire. The chief institutions of the organisation are the Commonwealth Secretariat, which focuses on intergovernmental aspects, and the Commonwealth Foundation, which focuses on non-governmental relations amongst member states. Numerous organisations are associated with and operate within the Commonwealth. The Commonwealth dates back to the first half of the 20th century with the decolonisation of the British Empire through increased self-governance of its territories. It was originally created as the British Commonwealth of Nations through the Balfour Declaration at the 1926 Imperial Conference, and formalised by the United Kingdom through the Statute of Westminster in 1931. The current Commonwealth of Nations was formally constituted by the London Declaration in 1949, which modernised the comm ...

Rectangular
In Euclidean geometry, Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle. A rectangle with four sides of equal length is a ''square''. The term "wikt:oblong, oblong" is occasionally used to refer to a non-square rectangle. A rectangle with Vertex (geometry), vertices ''ABCD'' would be denoted as . The word rectangle comes from the Latin ''rectangulus'', which is a combination of ''rectus'' (as an adjective, right, proper) and ''angulus'' (angle). A #Crossed rectangles, crossed rectangle is a crossed (self-intersecting) quadrilateral which consists of two opposite sides of a rectangle along with the two diagonals (therefore only two sides are parallel). It is a special case of an antiparallelogram, and its angles are not right angles and not all equal, though opposite angles ...

Sealed Beam
A parabolic aluminized reflector lamp (PAR lamp or simply PAR) is a type of electric lamp that is widely used in commercial, residential, and transportation illumination. It produces a highly directional beam. Usage includes theatrical lighting, locomotive headlamps, aircraft landing lights, and residential and commercial recessed lights ("cans" in the United States). Many PAR lamps are of the sealed beam variety, with a parabolic reflector, one or more filaments, and a glass or plastic lens sealed permanently together as a unit. Originally introduced for road vehicle headlamp service, sealed beams have since been applied elsewhere. Halogen sealed beam lamps incorporate a halogen lamp within a quartz or hard glass envelope. Construction A PAR lamp consists of a light source, with lens and a parabolic reflector with a smooth aluminium surface determining the spread of the beam. The most common sealed beam type combines these three elements into an integral unit. The light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tatra T77
The Czechoslovakian Tatra 77 (T77) is by many considered to be the first serial-produced, truly aerodynamically-designed automobile. It was developed by Hans Ledwinka and Paul Jaray, the Zeppelin aerodynamic engineer. Launched in 1934, the Tatra 77 is a coach-built automobile, constructed on a platform chassis with a pressed box-section steel backbone rather than Tatra's trademark tubular chassis, and is powered by a rear-mounted 2.97-litre air-cooled V8 engine, in later series increased to a 3.4-litre engine. It possessed advanced engineering features, such as overhead valves, hemispherical combustion chambers, a dry sump, fully independent suspension, rear swing axles and extensive use of lightweight magnesium alloy for the engine, transmission, suspension and body. The average drag coefficient of a 1:5 model of Tatra 77 was recorded as 0.2455. The later model T77a has a top speed of over due to its advanced aerodynamic design which delivers an exceptionally low drag coefficien ...
