Mining lamp
LED (Light Emitting Diode), a light emitting diode, is a solid state semiconductor device that can convert electric energy into visible light. It can directly convert electricity into light. The heart of LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is a negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin.

LED lamp is a semiconductor material chip of electroluminescence, which is solidified on the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire. The periphery is sealed with epoxy resin to protect the internal core wire. Finally, the shell is installed, so the seismic resistance of LED lamp is good.
Before the advent of electric lamps, kerosene lamps or gas lamps were widely used as lighting tools. The lamp burns kerosene or gas, so it has strong black smoke and pungent odor, and it is inconvenient to add fuel and scrub the lampshade frequently. What's more, this kind of lamp is easy to cause fire and cause great disaster. For many years, many scientists have tried their best to invent a safe and convenient electric lamp.
In the Zhou Dynasty, bronze and pottery were widely used, creating conditions for the emergence of oil lamps. During the Spring and Autumn Period and the Warring States Period, oil lamps for lighting began to appear. Beans were the tools used for lighting at that time. They were made according to the shape of beans, the food utensil at that time. At that time, people used soybean fat as fuel, put it in a small pottery bowl, put a wick on it, and lit it.
"This is the 'bean' in the Spring and Autumn Period and the Warring States Period, which is the predecessor of the lamp." Qing Liejun explained while playing. In the Stone Age, people learned how to use fire for heating, cooking, controlling animals, and lighting. According to the unearthed oracle bone inscriptions, as early as the Yin and Shang Dynasties, humans used turpentine torches for lighting.
