- Q: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).
- Q:LED rechargeable flashlight can not charge, but plug in power can be bright, what is the reason?
- LED rechargeable flashlights can be recharged repeatedly using handheld electronic lighting tools. LED rechargeable flashlight consists of LED light source, shell, rechargeable battery, switch, circuit board and so on.
- Q: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.
- Q:Use LED lights and cell phone batteries to make flashlights?
- It depends on what LED is, if strawhat micro light LED, it depends on a few LED lights, and then the calculation, if the power of LED 3-5W, it can also direct drive in general, but for security reasons, can add a constant current voltage stabilizing circuit.
- Q:Does the non LED flashlight have a constant current drive circuit?
- No ordinary flashlight lamp power can be even as long as nothing more than take a switch
- Q:In the light rechargeable flashlight is how much?
- The terminal voltage of PN junction constitutes a certain barrier. When the forward bias voltage is applied, the potential barrier decreases, and the majority carrier in the P region and the N region diffuse to each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons will diffuse into the P region, which will result in the injection of minority carriers into the P region. These electrons are combined with holes in the valence band, and the energy is released in the form of light energy when combined. This is the principle of PN junction luminescence.
- Q:How much LED is on the flashlight? W?
- Power flashlight on the use of LED is not certain, the use of 1-3W pocket flashlight following general 10CM on LED, and more generally in the 3-5W, 10W or LED, and then a big multi section 18650 battery flashlight, you can use the 20-50W LED.
- Q:The market is generally concentrated LED flashlight, the probe has to do astigmatism flashlight?
- Focus on the riding torch, those are the spotlight, you can also astigmatism flashlight ah!
- Q:What's the use of a bright flashlight driver?
- Because if the battery drives LED directly, the voltage and current of the battery will decrease gradually, which will cause the instability of the light.
- Q:Is led flashlight used widely?
- LED flashlight is using high brightness light emitting diode as the light source, it has the advantages of high brightness, low energy consumption, environmental protection and energy saving, the use of long, generally applicable to mountain climbing, hiking, camping, riding, hunting, fishing, rescue, patrol, cave exploration, mining, homemade daily usage.
