Lampshades
A lampshade is a fixture that envelops the electric light, lightbulb on a light fixture, lamp to Diffuser (optics), diffuse the light it emits. Lampshades can be made out of a large variety of materials like paper, glass, fabric or stone. Often times conical or cylindrical in shape, lampshades can be found on floor, desk, tabletop, or suspended lamps. The term can also apply to the glass (or other materials) hung around many designs of ceiling lamp. Beyond its practical purpose, significant emphasis is also usually given to decorative and aesthetic features. A lamp shade also serves to "shade" human eyes from the direct glare of the light bulbs used to illuminate the lamp. Some lamp shades are also lined with a hard-backed opaque lining, often white or gold, to reflect as much light as possible through the top and bottom of the shade while blocking light from emitting through the walls of the shade itself. In other cases, the shade material is deliberately decorative so that u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Humphry Davy
Sir Humphry Davy, 1st Baronet, (17 December 177829 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited to have been the first to discover clathrate hydrates in his lab. In 1799 he experimented with nitrous oxide and was astonished at how it made him laugh, so he nicknamed it "laughing gas" and wrote about its potential anaesthetic properties in relieving pain during surgery. Davy was a baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), Fellow of the Geological Society (FGS), and a mem ...

Finial
A finial (from '' la, finis'', end) or hip-knob is an element marking the top or end of some object, often formed to be a decorative feature. In architecture, it is a small decorative device, employed to emphasize the apex of a dome, spire, tower, roof, or gable or any of various distinctive ornaments at the top, end, or corner of a building or structure. A finial is typically carved in stone. Where there are several such elements they may be called pinnacles. The very top of a finial can be a floral or foliated element called a bouquet. Smaller finials in materials such as metal or wood are used as a decorative ornament on the tops or ends of poles or rods such as tent-poles or curtain rods or any object such as a piece of furniture. These are frequently seen on top of bed posts or clocks. Decorative finials are also commonly used to fasten lampshades, and as an ornamental element at the end of the handles of souvenir spoons. The charm at the end of a pull chain (such as for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamp Harp
A lamp harp is the component of a lamp to which the lamp shade is attached. It typically comes in two separate parts, a saddle which is fastened under the lamp socket, and the harp itself which consist of a lightweight frame attached to the saddle at its lower end and extending upwards to a point above the bulb. At the top of the harp is a threaded rod. The shade's internal frame (known as a spider) mounts on this rod and is secured in place by a lamp finial. Common materials for harps include brass and nickel. The most common thread size is 1/4-27. References Interior design Light fixtures {{design-stub ...

Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus '' Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dat ...

Linen
Linen () is a textile made from the fibers of the flax plant. Linen is very strong, absorbent, and dries faster than cotton. Because of these properties, linen is comfortable to wear in hot weather and is valued for use in garments. It also has other distinctive characteristics, notably its tendency to wrinkle. Linen textiles appear to be some of the oldest in the world; their history goes back many thousands of years. Dyed flax fibers found in a cave in Southeastern Europe (present-day Georgia) suggest the use of woven linen fabrics from wild flax may date back over 30,000 years. Linen was used in ancient civilizations including Mesopotamia and ancient Egypt, and linen is mentioned in the Bible. In the 18th century and beyond, the linen industry was important in the economies of several countries in Europe as well as the American colonies. Textiles in a linen weave texture, even when made of cotton, hemp, or other non-flax fibers, are also loosely referred to as "linen". ...

Silk
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity ( sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes. The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, al ...

Incandescent Light Bulb
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting. Incandescent bulbs are much less efficient than other types of electric lighting, converting le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Göbel
Heinrich Göbel, or Henry Goebel (April 20, 1818 – December 4, 1893) was a German-born American precision mechanic and inventor. In 1848 he emigrated to New York City, where he resided until his death. He received American citizenship in 1865. In 1893, magazines and newspapers reported 25 years earlier, Göbel had developed incandescent light bulbs comparable to those invented in 1879 by Thomas Alva Edison. Göbel did not apply for a patent. In 1893, the Edison Electric Light Company sued three manufacturers of incandescent lamps for infringing Edison's patent. The defense of these companies claimed the Edison patent was void because of the same invention by Göbel 25 years earlier, which came to be known as the "Göbel defense". Judges of four courts raised doubts; there was no clear and convincing proof for the claimed invention. A research work published in 2007 concluded that the ''Goebel-Defense'' was fraudulent. After Göbel's death, in some countries, the legend arose h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
