Edison bulb in the online store

The nineteenth century was a time of extremely turbulent political, economic and social changes. For many, it may be associated with the struggle for freedom and independence (including Poles under partition), national uprisings against the prevailing order, or unification of countries like Germany and Italy. It should also be emphasized that it also resulted in many inventions and discoveries, which significantly influenced the improvement of people’s quality of life. Although many of us do not use them on a daily basis, or are not necessary for us to live - like a revolver or dynamite - however, there is a wide range of items that make life easier. In this group there is even a telephone, a tram, a radio and … an underrated light bulb.

Loft Edison bulb

For most of us, the concept of a bulb connects directly with Thomas Edison. We must, however, bear in mind that his name is only at the end of the cause-and-effect process, which ended with the patenting of this invention in 1879. The first attempts to keep the light were carried out since 1838 by Jobard - a carbon fiber glowing in a vacuum. Two years later, a man named Robert Grove tried to obtain a lasting effect of keeping the light with a platinum wire. It was not until 1854 that the first practical use of a light bulb for advertising, with a fiber made of charred bamboo, took place. In 1860, Joseph Wilson Swan patented a glowing carbon fiber in a bubble from which the air was removed. The same inventor in 1878 patented the first bulbs suitable for mass use, and mass production started in the same year in the US thanks to Hiram Stevens Maxim. A year later Thomas Alva Edison obtained a patent for his bulb.

Thomas Alva Edison, who lived in 1847-1931, went down in history as a valued inventor and entrepreneur. It is he who is credited with inventing an electric bulb, which he patented in 1879. After the trials of Jobard, Grove and others, Edison managed to get a lasting effect of keeping the light. Despite the fact that his methods of patent law enforcement aroused and still arouse much controversy, and the authorship of some inventions is widely questioned, Edison’s name was inseparable from the bulb.

A light bulb is nothing more than an electric light source in which a fiber made of a hardly meltable material (originally graphite, now tungsten) is a glowing body in it. That fiber vel. tungsten wire, placed in a glass bulb with a mixture of noble gases, reaches a temperature of approx. 2500-3000 K due to the flow of electric current. The light obtained from the bulb is similar to sunlight. One of the biggest advantages is the good color rendering index of objects viewed in this light, as well as the fact that it shines all the time. The spectrum of the light emitted by the bulb is continuous, has a lower color temperature - it is more yellow - than sunlight.

Although electricity was already widely used at the end of the 19th century, it was not yet considered about the popularization of electricity on a massive scale. The invention of Edison’s practical bulb has created the need to supply electricity to a larger number of recipients. Thomas Edison also built the world’s first public utility plant based in New York. It had 6 direct current generators operated by steam engines with a power of 125 HP and supplied with 110 V electricity network, to which 7,200 light bulbs were attached.

Traditional and ordinary incandescent bulbs (also called incandescent lamps or tungsten bulbs) are slowly withdrawn from the market mainly due to high operating costs. These bulbs are the least durable and at the same time the most emergency. The development of traditional bulbs are halogen lamps (halogen lamps). They have a slightly higher durability while consuming up to 30% less energy compared to their usual predecessor. Another type of light bulbs are compact fluorescent lamps having different shapes, intended for use in traditional lamps. Fluorescent lamps generate much more light than ordinary light bulbs. Their life reaches up to 15 thousand. hours, but remember to dispose of them properly because of the mercury content. The most modern light source are LED bulbs. They are primarily characterized by significantly longer durability than other available on the market (as well as in online stores) light sources and impressive electrical efficiency. Currently, it is the most energy-efficient source of light, does not emit UV rays and is not made of harmful substances.

Despite a large list of modern types and models of light bulbs, it is the prototype of the Edison bulb that enjoys considerable interest and returns to favor. In the online store Lunares.pl you can find several (a dozen or so) models referring to the invention of Edison. In the bulb bulb there is a braided carbon wire several times. Delicate light will create a unique atmosphere of any interior, giving it a pleasant warmth.
