FAQ
- I bought a bright spot flashlight (Q5 flashlight, LED long-range flashlight), the battery with a charge will not go in
- Because you open the battery directly in charge, it is equivalent to a conductor, directly to the flashlight power supply, and you do not plug when the battery is scrapped, no electricity, so it will be dark for a while!
- Now most LED flashlights are using resistance to drop voltage charging, waste a lot of energy, why manufacturers like to use?
- When you turn on the flashlight, you see the simple circuit, and the general mobile phone has an external charger. They did notThat is to say, use 230V to direct decompression.
- What kind of battery does flashlight LED charge type use?
- In general, the rechargeable battery LED flashlight there are two common categories. One is ordinary cheap plastic rechargeable LED flashlight, low light long LED, commonly used lead-acid rechargeable battery, the other is a high-power LED flashlight, rechargeable lithium batteries in common, such as 186501634014500. Of course, there are a variety of 1.2V Ni MH charging the battery.
- LED flashlight structure and manufacturing method
- The principle of LED luminescence is similar. But the difference is, LED is not through the electronic transitions inside the atom to emit light, but by applying a voltage across the PN junction LED, the PN junction itself in a level form (in fact, is a series of energy), then the electrons at this level and jump to the light emitting photons.
- How does the rechargeable LED flashlight detect the quality of the batteries inside?
- Rechargeable flashlights are designed for energy saving and environmental protection, as well as for manufacturers to adapt to consumer needs and reflect social responsibilities. The emergence of rechargeable flashlights solves the trouble of replacing batteries, and also protects the environment resources advantageously.
- Flashlight long shots selected focus or zoom well
- The variable focus cylinder has poor workmanship and low light efficiency
- Is led flashlight damaged easily?
- Unable。 WuYou excellent flashlight is very strong and not easy to break. Last year, my friend sent me one. I still use it at home. Sometimes I have to wear a flashlight when the power is out of order.
- What about magtac64 2-cell CR123 LED flashlight?
- The battery has a great influence on selection of battery flashlight brightness and battery life, lithium battery can be used repeatedly, and has the characteristics of high capacity, the overall life is longer, and largely saves the cost, but not easy to buy a single, short life, dry batteries can better play the big power LED effect, high stability, and single use time is long, and easy to buy, but the batteries need to be replaced, the cost increase, foreign people generally love battery, domestic friends mostly choose lithium battery. This is the parameter of CREE LED, more than this is generally virtual standard.
