FAQ
- Can the battery of the LED flashlight be distilled?
- This kind of battery damage, usually after the use of electricity, did not promptly add electricity caused by internal plate sulfide caused by the complement of distilled water can not solve the problem, can only be scrapped. In fact, even if the water is useless, after the battery will water rich liquid, resulting in leakage, there are a lot of mist overflow, that will not only internal components caused by the leakage corrosion will cause injury and leakage (due to charge the flashlight are capacitor directly down pressure, no isolation transformer).
- Why hold a few moving magnets, manual power LED flashlight bulb will shine?
- A magnetic magnet is used to move downward, the magnet field line cuts the coil on the periphery of the magnet, and the coil generates electricity to recharge the rechargeable batteries at both ends of the coil, so that the LED bulb emits light.
- How to transform a regular LED flashlight into a blue light?
- 1, needs to buy blue light LED lamp diode;2, open the LED flashlight, the original LED diode is removed and replaced with blue LED diodes, connected by soldering solder joint;
- What is a LED flashlight used for?
- LED flashlight brightness must be high, the life time can be relatively short, at the same time, with the best anti shock characteristics of a flashlight, so as not to be part of a gun recoil shock damage. This kind of flashlight does not need to be too wide and light to moderate.
- How to make the simplest 1.5 volt LED energy-saving lamp, flashlight?
- The comrade upstairs was not quite right. Positive guide of white LED through voltage does more than 1 batteries, but the market does have a battery power supply using the LED flashlight, before the "radio" magazine also introduced, you can use a simple self-excited shunt switch power boost, and then drive LED. At that time the magazine for circuit drawings, switch 13001 as a side switch with a small power, coupled with the control base current on a secondary resistor, with a 1N4148 high frequency rectifier, transformer with high frequency magnetic ballast inside the winding. This circuit is very simple, I have not tried. But I used the voltage circuit structure of 6V is similar to the EI power transformer lighting fluorescent lamp, the boost circuit is feasible. The original circuit I can not find, the following illustration of the picture for reference only, the first side of the same structure, the two side does not need to double voltage rectifier circuit, the direct 4148 half wave rectifier is ok. Similar circuit in Baidu pictures search there are many, there is no transformer structure, the use of inductance step-up.
- How can I make a phone call flashing? The flashlight light is not a Led light
- Generally in the settings / display inside, you look for, and some phones come with flashlights, LED lights, and some mobile phones to use software to open the mobile phone flashlight, that is, the camera behind the flash continues to shine
- How long has the LED flashlight battery been repaired?
- When disassembling the lamp holder, you can insert the screwdriver or iron nail with a round head into the two holes on the aluminum ring at the bottom of the lamp holder. 3., then turn it gently. Note that the aluminum ring can be rotated easily if it is well maintained and has not been deformed by extrusion.
- What's the flashlight industry standard?
- LED flashlight selection criteria can not be separated from the international trade standards. Jin Ruide science and technology flashlight products have always followed the international ANSI flashlight standards, and constantly enhance the quality and performance of the battery.
