Flashlight: (English: Flashlight or Torch), short for flashlight, is a hand-held electronic lighting tool. A typical flashlight has a battery powered bulb and a focusing mirror, and a handle type housing for handheld use. Although it is a fairly simple design, it was not invented until the late 19th century, because it must combine the invention of the battery and the electric light bulb.
In the early days, because the storage power of the battery was insufficient, it was called "Flashlight" in English, which means a short light.
The birth of flashlight
Modern civilization should really thank Thomas Edison, the American inventor, who made the first white lamp with commercial value and brought light to mankind. However, Conrad Hubert deserves the same respect. He immigrated from Russia to the United States 100 years ago and invented the flashlight. When Hubert came home from work, a friend proudly showed him a shining flowerpot. It turned out that he installed a battery and a small light bulb in the flowerpot. As soon as the switch is turned on, the bulb lights up the flowers and looks dazzling.
Hubert was fascinated, and this incident gave him inspiration. He sometimes walks in the dark at night. It is inconvenient to walk one foot high and one foot low. Not long ago, he had to carry a heavy oil lamp to the dark basement to find something. He thought that it would be practical and convenient to use electric lights for portable lighting? So Hubert put the battery and the bulb in a tube, and the first mobile lighting flashlight came out.
Lighting history
The development of mobile lighting tools can be traced back to the early stage of human society - primitive society. Since human beings learned to drill wood to make fire, mobile lighting has experienced the development process from fire, oil, candles to flashlights. Mobile lighting tools have experienced countless changes, from torch, oil lamp, candle, kerosene lamp to incandescent bulb flashlight, xenon bulb flashlight, to a variety of LED flashlights. The oil lamp has been improved many times. The oil used for oil lamps is changed from animal oil to vegetable oil, and finally replaced by kerosene. In order to prevent the wind from blowing out the fire, people put a cover on the oil lamp. From the early paper cover to the later glass cover, such oil lamp is not afraid of the wind and is convenient for outdoor mobile lighting. While using oil lamps for lighting, humans are still looking for other mobile lighting methods. Around the third century BC, someone made candles out of beeswax. In the 18th century, candles made of paraffin wax appeared and began to be mass produced by machines. More than 100 years ago, the British invented the gas lamp, which made a big step forward in human lighting methods. Torches, candles, oil lamps, gas lamps and other movable lighting tools are all lit by the light from burning materials. At the end of the 19th century, Edison invented the electric light, which has rewritten the history of human lighting, and mankind has entered the era of electric lighting.
Rudiment of flashlight
Edison invented the light bulb, Volt invented the battery, and invented the real flashlight. However, the luminous performance of the bulb is very unstable, which is always bright and dark, so it is called "Flashlight". It was not until the late 1960s, with the advent of alkaline batteries, that the "lighting function" of flashlights was completed
