The First Experiments with Portable Electric Lighting
The battery was patented in 1800 by Alessandro Volta. That it was not widely usable product. There was still a long way to go before it would be ready.
That made for a program towards portable electric light for the moment, but a little bit, because there was no available power source. This changed in 1879, when both Joseph Swan and Thomas Edison invented the light bulb announced world. Click Garyflashlights to read more about the invention of the LED flashlight.
Pretty soon after they began to experiment in Europe and the United States with electrical forms of portable lights. In addition, they used both so-called “wet” and “dry” batteries. Although the term “dry cell” is a bit misleading; in a dry battery is just less moisture and acid than in a wet battery. In each case, the inventors came to a first number of lamps.
Precursors of the Flashlight
Between 1880 and 1895 the first portable electric lamps introduced in the market. They called them hand lamps or simply lanterns. Convenient although hardly. They were heavy, rectangular boxes that had roughly the size of a sewing machine and that you had to wear a lever. In the closet was the battery. The light was installed at the front or was mounted on top.
1891 was a stick with electric lights on the market, “electric cane. This required separate batteries made that fit in the stocks. The tip of the cane was the lamp and the lens. It is not clear how successful “electric cane” at the time. It is clear that he has not been for a long time.
About the same time still curieuzere portable lamp was made, namely electric tie pin. This was both a form of decoration as a real source of illumination. You can read a book in the dark if you wanted it.
I was the first generation with a wet tie pins battery that must be shipped in a separate bag. There is also joined to common acid leaked out of the bag, no doubt to the dismay of the environment by the owner. This tie pin was therefore not exactly a resounding commercial success.
in 1903, there were new electrical pins and brooches, in this market, which was tied to a dry battery. This battery fits typically in the pocket of a shirt or blouse. The new jewelry was also slightly more popular than its predecessor and had a wide selection of finishes.
