Explosion-proof flashlight fever hot normal?

There are many situations that can cause the battery to become hot

Lithium batteries cause hot causes:

1, battery 0 voltage will make the battery internal resistance becomes very large, will consume a lot of current when charging, and even your charger's current is not enough it is consumed.

2. After the voltage of the battery 0, the liquid inside the battery dries out. In the charging process, the dry substance reacts violently to emit heat.

3. After the battery 0 voltage, there may be a micro-short circuit inside the pole piece, which causes the battery to self-discharge continuously and generate heat.

The main reason for the hot flashlight is due to the lamp beads and IC or capacitance.

Flashlights commonly used lamp beads have CREE lamp beads, wafers and other brands. The lamp beads used by our company are all CREE lamp beads.

First, the brightness is strong. Large current withstand.

Second, the lamp life, performance is better than other brands. If the lamp bears a current of 1.2A. If the flashlight is 1A, the current is too high. He needs to be cooled like the outside, if there is a 350 Am current, there will be no hot flashlight. But the effect of brightness has also dropped. Flashlight fever is a normal phenomenon, but if it is hot, turn it off and let it buffer.

Some flashlights will cause the barrel to become hot while the flashlight is in use. This is also a normal phenomenon, whether it is explosion-proof flashlight or led flashlight, the principle of its composition are the same. Lamp beads, plus the performance of other components cause the flashlight to become hot. Flashlight fever is because the realization of the highlight function requires a large amount of energy to drive, LED will produce a certain amount of heat when driving. This is a normal phenomenon.

The above is new information released by Ronglang Electric Co., Ltd. The company provides explosion-proof flashlights, explosion-proof headlights, explosion-proof clean fluorescent lamps, LED explosion-proof lights and other products.

Explosion-proof flashlight hot, in fact, this is a normal phenomenon, the higher the brightness, the greater the heat. Explosion-proof flashlights are like this, but it does not matter in use, unless the temperature will be so high that you can not hold it, it is quality problems Now.

Generally, the explosion-proof flashlight is not obvious when it is used in ordinary brightness, and it is easy to feel heat when it is used in high brightness. This is because the realization of the highlight function requires high-power energy to drive in high-power driving. At the same time, the LED generates a certain amount of heat. This is a normal phenomenon. If you continue to use the highlight function, the heat will accumulate more and continue to spread out. Therefore, the phenomenon of flashlight heating will obviously be felt. Under normal circumstances, ordinary brightness can meet the needs of daily life, therefore, it is not recommended to use the highlight function continuously for a long time. There is also a situation that the reason for the low price on the Internet is that in order to lower the cost of flashlights and obtain higher profits, the quality of the circuit boards is poor, and the quality of the aluminum alloy material of flashlights will affect the heat dissipation of flashlights. Therefore, it is recommended to buy them. Flashlight to the regular manufacturers or agents. Most cottage flashlights, in pursuit of higher brightness, are generally driven by currents that exceed safety standards, but such lifetimes are greatly reduced, and heating is also greater. Moreover, the 18650 battery is not as big as the 3800, and it is printed casually. Actually it can have 1800 is not bad.
