Nowadays flashlight is not used as frequently as it is used in the past, but as a convenient and portable tool for giving off light, it is still very necessary, and it is certain that it will never disappear. It was Conrad ? Huber, who immigrated from Russia to America, that invented the first flashlight in the world. More than one hundred years ago, after returning home from work, Huber saw one flowerpot of his friend that could give off light, the friend had put one bulb and one battery in the flowerpot, thus when the bulb was turned on, the flowerpot could give off light, Huber was enlightened by this, before long he had looked for something using the bulky lamp in the darkness, and sometimes he had to walk in the darkness very inconveniently, thus he imagined that it would be very convenient if he could take the bulb along. As a result, Huber put the battery and bulb in one tube, then the first flashlight in the world saw the light. This was called flashlight, maybe because that the early designed flashlight could be used only for a short time, for the battery could not store much electricity, thus the flashlight means “short light”.
In fact, unlike it seems that the flashlight can only used for lighting, it has many other advantages such as intimidation, alarm, high-voltage self-defense and so on. And at the present time the LED flashlight is used most frequently. Multifunctional flashlight now is very necessary in the daily life, for example, if we go out for a trip and walk in the rugged road full of ups and downs, when we encounter some wild animal and criminal, we can send the alarm in order to frighten them away by using the multifunctional flashlight, if they attack us, we can use the high voltage of the flashlight to defense ourselves, at the same time, the loud alarm can help you summon the rescue personnel around.
Even at present we live in such a modern society, and the electricity will not be cut off, however, in our home a flashlight is very necessary. Besides, when using the torch, we should also pay attention to very small details, for example, we should exchange the battery or charge the battery in time, we should keep the flashlight off water, because water can break the circuit board and lead to short circuit.
