This article is about a botanical term. For electric bulb, see light bulb.
In botany, the term bulb is used to refer to a underground or surface storage organ. It consists of a modified stem which bears swollen leaf bases, often as scales. These leaf bases generally do not support leaves, but contain food reserves to enable the plant to survive adverse weather. The leaf bases may overlap and surround the center of the bulb as with lilies, or may completely surround the inner regions of the bulb, as with the onion. The modified stem forms the base of the bulb, and plant growth occurs from this base. Roots emerge from the underside of the base, and new stems and leaves from the upper side.
Cultivated plants that form true bulbs include;
Some epiphytic orchids form bulb-like above ground storage organs, called pseudobulbs.
- onions, garlics, and many other Alliums,
- lily, tulips and many other members of the lily family,
- Amaryllis, Hippeastrum, Narcissus, and many other members of the Amaryllis family,
- Some species of Iris.
Other types of storage organ are often called bulbs. See corm, rhizome, tuber.
Bulb is one of the very few words in the English language that doesn't rhyme with anything. See List of English words without rhymes.

(From Wikipedia, the free Encyclopedia)
The electric light bulb uses a glowing wire filament heated by electrical resistance to white heat to generate light (a process known as thermal radiation). The 'bulb' is the glass enclosure which keeps the filament in a vacuum or low-pressure noble gas (or halogen gas in the case of quartz-halogen lamps: see below).
History of the light bulb
The invention of the light bulb is sometimes attributed to Thomas Alva Edison. In fact Edison was just one of many who contributed to the development of a truly practical device for the production of electrically generated lighting.
In 1801 Sir Humphry Davy, an English chemist, made platinum strips glow by passing an electric current through them, but the strips oxidized too quickly to make a useful lamp. In 1809 he created the first arc lamp, which he demonstrated to the Royal Institution of Great Britain in 1810, by creating a small but blinding arc between two charcoal rods connected to a battery.
In 1820 a British scientist Warren De la Rue enclosed a platinum coil in an evacuated tube and passed an electric current through it. The design was based on the concept that the high melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain less gas particles to react with the platinum, improving its longevity. Although it was an efficient design, the cost of the platinum made it impractical for commercial use.
In 1835 James Bowman Lindsay demonstrated a constant electric light at a public meeting in Dundee. He stated that he could "read a book at a distance of one and a half foot". However having perfected the device, to his own satisfaction, he turned to the problem of wireless telegrahy and did not develop the electric light any further.
In 1841 Frederick de Moleyns of England was granted the first patent for an incandescent lamp, with a design using powdered charcoal heated between two platinum wires.
In 1854, the German inventor Heinrich Goebel developed what may have been the first practical light bulb, using a carbonized bamboo fibre as the filament. His lamps lasted for up to 400 hours. He did not immediately apply for a patent, but his priority was established in 1893.
Joseph Wilson Swan(1828-1914) was a physicist and chemist born in Sunderland, England. In 1850 the British pioneer began working with carbonized paper filaments in an evacuated glass bulb. By 1860 he was able to demonstrate a working device but lack of a good vacuum and an adequate supply of electricity resulted in a short lifetime for the bulb and inefficient light. By the mid-1870s better pumps became available, and Swan returned to his experiments. Swan received a British patent for his device in 1878. Swan reported success to the Newcastle Chemical Society and at a lecture in Newcastle in February 1879 he demonstrated a working lamp that utilized a carbon fibre filament. The most significant feature of Swan's lamp was that there was little residual oxygen in the vacuum tube to ignite the filament, thus allowing the filament to glow almost white-hot without catching fire. From this year he began installing light bulbs in homes and landmarks in England and by the early 1880s had started his own company.
Across the Atlantic, parallel developments were also taking place. On July 24, 1874 a Canadian patent was filed for the Woodward and Evan's Light by a Toronto medical electrician named Henry Woodward and a colleague Mathew Evans, who was described in the patent as a "Gentleman" but in reality a hotel keeper. They built their lamp with a shaped rod of carbon held between electrodes in an glass bulb filled with nitrogen. Woodward and Evans found it impossible to raise financial support for the development of their invention and in 1875 Woodward sold a share of their Canadian patent to Thomas Edison.
US223898 Electric LampEdison purchased the Woodward and Evans patent and had a team of developers earch for alternative filament material. Eventually he utilized a carbon filament that burned for forty hours (first successful test was on October 21, 1879; it lasted 13 1/2 hours). Edison continued to improve their design. By 1880 he had a device that could last for over 1200 hours using a bamboo-derived filament, longer than the 400 hours of Heinrich Goebel's earlier light bulb.
In Britain, Swan took Edison to court for patent infringement. Edison lost and as part of the settlement, Edison was forced to take Swan in as a partner in his British electric works. The company was called the Edison and Swan United Electric Company. Eventually, Edison acquired all of Swan's interest in the company. Swan sold his U.S. patent rights to the Brush Electric Company in June 1882.
The U.S. Patent Office had ruled on October 8, 1883 that Edison's patents were based on the prior art of William Sawyer and were invalid. Litigation continued for a number of years. Eventually on October 6, 1889, a judge ruled that Edison's electric light improvement claim for "a filament of carbon of high resistance" was valid. Research exposed in "A Streak of Luck" by Robert Conot (1979), shows that Edison and his attorneys hid significant information from the judge. They cut out the October 7-21, 1879 section of a notebook that the judge might have determined showed that they were simply extending Sawyer's (or Swan's) work with carbon "burners" or "rods" in an evacuated glass bulb.
Edison and his team did not find a commercially workable filament (bamboo) until more than 6 months after Edison filed the patent application. The weak and short lived (40-150 hours) carbon filament was eventually superseded by the tungsten filament. In 1903 Willis Whitnew invented a filament that would not make the inside of a lightbulb turn dark. It was a metal-coated carbon filament. In 1906, the General Electric Company were the first to patent a method of making tungsten filaments for use in incandescent lightbulbs. The filaments were costly, but by 1910 William David Coolidge (1873-1975) had invented an improved method of making tungsten filaments. The tungsten filament outlasted all other types of filaments and Coolidge made the costs practical.
One of the major problems of the standard electric light bulb is evaporation of the filament, leading to narrowing. Where the filament is narrower, electrical resistance is higher (due to the smaller cross-section) and the filament heats up more, increasing the rate of evaporation further at that point. The end point of this process is the failure of the filament.
This problem is addressed in the halogen lamp which is filled with halogen gas. This creates an equilibrium reaction where evaporated filament is chemically re-deposited at the hot-spots, preventing the early failure of the lamp. This allows halogen lamps to be run at higher temperatures which would cause unacceptable low lamp lifetimes in ordinary light bulbs, allowing for greater brightness and efficiency.
The incandescent light bulb is still widely used in domestic applications, and is the basis of most portable lighting (for instance, some car headlamps and electric torcheses). Halogen lights have become more common in auto headlights and domestic situations, particularly where light is to be concentrated on a particular point. The fluorescent light, has, however, replaced many applications of the light bulb with its superior life and energy efficiency. LED lights are beginning to see increased home and auto use, replacing incandescent bulbs.
Standard fittings
Most domestic and industrial light bulbs have standard fittings compatible with standard lampholders. Common types of fitting are:
- MES or medium Edison screw, used in USA for lamps
- BC or bayonet cap, used in UK for mains lamps
Efficiency
Luminous efficiency is defined as the ratio of luminous flux to total radiated flux, and is measured in lumen per watt (lm/W) or as a percentage of 680 lm/W, the efficiency of a monochromatic source of wavelength 556 nm (a yellow-green colour to which the human eye is most sensitive).A different measure, the overall luminous efficiency, is defined as the ratio of luminous flux to total energy input. This is less than or equal to the luminous efficiency.

Heat
A fluorescent lamp, which is approximately 8 times more efficient than an incandescent lamp, will produce 8 times less heat, assuming the same levels of light from both sources. This is one reason why fluorescent lighting is so popular in commercial spaces.
