Reducing eye strain is thought to increase productivity. It was on this combination that the Emeralit was marketed, as it was marketed as a tool that could increase productivity, and not just as a beautiful lamp. In addition, people working in the office needed efficient and targeted lighting that could add its characteristic green hue to the banker`s lamp. The first patent for a banker`s lamp was filed on May 11, 1909 by Harrison D. McFaddin and manufactured and sold under the brand name Emeralite („emerald” and „light”). The emerald lampshades were manufactured by the J. Schreiber & Nephew factory in Rapotín, Moravia. [1] Later, competitors were sold as „Greenalite”, „Verdelite” and „Amronlite”. [2] Excellent article! The library of the Czech Academy of Sciences in Prague also has green lampshades. Today, most banks, courtrooms, and libraries have other types of lamps, but they are still used in movie scenes set in one of these locations. Some examples are this banking scene from „500 Days of Summer”, this library scene from David Fincher`s „Seven” or these court scenes of „law-abiding citizen” and „legal blonde”.

Although this theory that green tones are psychologically soothing, cause less eye strain and increase productivity, has been more or less debunked because it`s easy to see why. The green hue emits a pleasant light, which makes the theory believable. Combined with clever marketing and design, it`s no wonder they sold well and cemented their position as a classic desk lamp. A British version of the Banker lamp was patented in 1929, which has a solid brass lampshade or reflector instead of a glass lampshade. In addition, the positions of the base and lampshade are adjustable. [3] Examples are often observed in the second-hand market. The Grande Bibliothèque/BAnQ in Montreal, QC, Canada also uses green lampshades, as does the Russian State Library in Moscow, Russia. Finally, my library story and my knowledge of interior design can be combined! In the world of decoration, these banker`s lamps or lamps „Emeralite” are called, they were a very popular lamp style at the turn of the century, there is nothing particularly bookcase for them, and the style is still popular in interior design. They were a popular and effective form of workplace lighting at the time when these libraries were probably equipped for electric lighting, really nothing more. They stay nearby because they are cute little lamps! Green is considered in our society as a color that calms the eyes (like green spaces for actors), although I think the benefits of colors on vision have been scientifically proven to be nonsense, so it does not reduce eye strain. Modern libraries generally no longer use workplace lighting because it is not energy efficient (who wants to walk around and turn off 50 lights before closing the library?).

I bathe in fluorescent horror while I work. I`ve seen a few modern tiles (it`s those cubby things you only see in bookcases) that have work lighting, but it`s those standard booths that go fluorescent under the mounting. List of libraries with green lampshades/banker`s lamps: However, you are likely to encounter a green banker`s lamp, or at least lamps with green lampshades, in older libraries such as the Boston Public Library, the French National Library in Paris, and the Royal Library in Copenhagen. If you know of a library that uses green lampshades or banker`s lamps, comment below so I can update the list. Hello! There are green lamps at the National Parliamentary Library of Ukraine in Kiev. The answer is relatively simple. At the turn of the century, many public buildings were equipped with electric lighting, which meant they needed electric lamps. It turns out that at this time the banker`s lamp gained importance. Although most people notice the banker`s lamp after watching one in movies and TV shows, some careful observers may have encountered one in a courtroom or library. You`ve probably seen one in a library somewhere, as they`re not that common in courtrooms anymore.

Nevertheless, this is one of the reasons why they appear in movies in banks, libraries and courtrooms, as they were common there. I`ve been to a lot of old libraries around the world and one thing that`s common in old libraries, especially here in Europe, is these green lampshades like in this picture: i.imgur.com/ilA47MQ.jpg they stay because they`re cute little lamps! The House of Lords Library in Britain was built in the 1800s. The banker`s lamp originated in the United States with the introduction of Emeralite. This is a type of desk or electric table lamp characterized by a brass stand, a green glass lampshade, and a powertrain switch (although modern versions can use other types of switches). It is often used in libraries in the United States, which popularized the lamp thanks to its presence in movies and television series. Other examples may have different glass colors. If you look at old images, it seems that they have hardly changed. I guess at some point it became a tradition.

But is there an explanation for why green lampshades in libraries seem to have been something like this? The Boston Athenaeum. I went for a ride today and someone asked me why the lamps in libraries are green and I didn`t know. Thank you very much for this post. The first electric lamps were equipped with light bulbs, which emitted a fairly bright light that could strain the eyes if exposed for hours. This led to the idea of developing something to reduce eye strain from the light source. I`m not sure what you`re saying here, but your eyes are certainly more sensitive to green light than, say, red. This would mean that you need less intensity to see through the green light. I have no idea if that means less eye strain or more. Although I think the benefits of colors on vision have been scientifically proven to be nonsense, so it does not reduce eye strain. The company that did it has a page of history, it`s not bad. They came in other colors, but I think green was the most popular.

It`s a pretty shade of green! Укажите страну проживания, используемые язык и валюту. Подробнее. This design-related article is a stub. You can help Wikipedia by expanding it.
