Oil Lamp
The lamps have been used to diffuse the light from ancient times, even before electricity was invented, and lighting was given a new meaning. The use of the lamps can be divided into two eras: The pre-electric era and the post-electrical.
The pre-electric
The invention and the first use of the lamp can be traced back to 70,000 BC. At that time, there was no metal or bronze to make lamps instead of civilization then uses rocks hollow shells. These hollow rocks were filled with moss and other natural substances and soaked in animal fat. Animal fat acted as oil and that's how you light the lamps first.
With the advent of pottery and bronze and copper age, humans began to make lamps that imitated other natural forms. Wicks came into existence much later and were used for flame control or flame speed. In the 7th century BC, the Greeks began to use terracotta lamps, It replaces the handheld torches. The lamp of the word has been derived from the Greek word hoes, meaning torch.
Lamps and changing design:
There was a significant change in the design of lamps in the 18th century, when central burner was invented. With the invention of the recorder, a source fuel was made of metal. Another small change made was the addition of a metal tube that could be adjusted to control the intensity of the flame or light.
This was a breakthrough in terms of lighting, as with the setting, human beings were able to decrease the lighting or make it bright as necessary. Another aspect that was added to the new lamp, which was in the form of small glass chimneys. The role of the glass chimney was to protect the flame, and how to control the air flow.
The Swiss chemist Ami Argand uses a circular hollow wick oil lamp for the first time in 1783.
Fuels lighting
Different types of fuels have been used for the lighting of a lamp of between 70,000 a. C. and now. Most of the early forms fuel were beeswax, olive oil, animal fat, fish oil, sesame oil, whale oil, walnut oil etc. were also among the forms most widely used fuel for lighting a lamp until the late 18th century.
Around 1859, the drilling process first began to find With oil and the advent of kerosene, which is a petroleum product, the lamp became more popular and widely used. Kerosene lighting was introduced enabled first in Germany in 1853.
During the same time two other products are used for purposes of lighting the lamp and are natural gas and coal. The first use of coal gas lamps was in 1784.
Lamps electric lighting:
Lamps have come a long way from the use of coal gas to electricity. In 1801, Sir Humphrey Davy of England invented the electric arc lamp carbon, which was the first of its kind. The operating principle for this lamp was simple and involved coupling of two carbon rods to an electrical source.
The carbon rods are kept at a distance apart so that the Electric current can flow through the arc and thus vaporize carbon to create white light. Around 1857, AE Becquerel of France came up with the theory of lighting fluorescent lighting. In the 1870s, the unthinkable happened to Thomas Edison invents the first incandescent electric lamp. Since then, incandescent lamps were used for lighting purposes in homes until about the 20th century principles.
In 1901, Peter Cooper Hewitt patented his invention, the mercury vapor lamp. It was another type of arc lamp illumination enhanced using mercury vapors, which were locked in a glass ampoule. On The mercury vapor lamps set the prototype for the fluorescent light bulbs.
The neon lamp was invented Georges Claude of France in 1911, followed by Irving Langmuir, an American who invented the electric gas-filled incandescent lamp in 1915. In 1927, Hans Spanner, Friedrich Meyer, and Edmund Germer patented the first fluorescent lamp. Fluorescent lamps provide better illumination, compared with lamps Mercury vapor as they were covered from inside with beryllium.
Since then we have been using various forms of lighting in lamps, including Mercury vapor, incandescent lamps and even today, in some corners of the world people still use the old wick and oil lamp for lighting from their homes.
