Under normal circumstances, ampoules do not explode on contact with water vapor. Bulb explosions occur due to sudden cooling and sudden heating, as well as drastic changes in temperature causing the bulb glass to break. The hot bulb is suddenly splashed with cold water. It's the same as filling a glass with boiling water in winter. Additionally, even if the bulb explodes, the filament will burn out instantly. Since the humidity in the air (water vapor) is far from supersaturated, there will be no air conduction incidents or injuries. Another point to note: in fact, water (H2O) does not conduct electricity. The so-called daily conductivity of water is due to the fact that ordinary water contains a large number of conductive particles, such as zinc, magnesium, iron, calcium and other impurities, among others. conductive ions. Water becomes an electrical conductor. The water couldre does not conduct electricity.
You have never seen it before, and it is probably difficult to popularize it, because, except for very special occasions, it is convenient and cheap to have electricity.
The LED is a component that must use electricity to light up. Not using electricity means not using batteries. Where does the energy come from? It is necessary to convert other forms of energy into electrical energy to use it. The simplest and most straightforward is the fuel cell. No matter what type of energy is ultimately converted into electricity, how can it be said that it does not use electricity? !
Unless it's not an LED light source, but a non-electroluminescence involving water, that's too avant-garde, I'm looking forward to that! But "there is also a screw port that can be used for electricity" means it also has electroluminescence function.Oh my god, your friend is either ignorant or an expert.
