FAQ
- What's the resistance on the LED flashlight?
- LED is a light emitting diode, belonging to semiconductor lighting. A silicon PN section of the pressure drop is 0.7V, a light emitting diode operating current is 10--20mA, the battery general 2 section, voltage is 3V, light-emitting diode is commonly used in parallel
- What kind of batteries do LED flashlights usually use?
- Flashlight flashlight is generally used in lithium batteries and dry batteries, and now we use the lithium battery flashlight more, because lithium batteries can charge, more convenient point, will not pollute the environment, more environmentally friendly.
- LED flashlight 16 lamp can change a need for what?
- Instead of one, it's not so bright
- 10W's LED bright flashlight is on all the time. How much is the power per hour?
- Battery voltage 12V, 10W is 833mA, power consumption 833mAh per hour.
- What are the disadvantages of a LED flashlight?
- The disadvantage is the heat problem, if the poor heat dissipation will greatly shorten the life, flashlight factory in the design and production, need to fully consider the heat problem of flashlight, so as to avoid unnecessary damage.
- Just bought Led flashlight flashlight, 5 hours charging 9 hours of electricity, and now there is no electricity, but the charger shows full power, but it is not bright, what is the matter?
- The cap of the lithium ion battery is provided with an explosion proof hole, and when the internal pressure is too large, the explosion-proof hole automatically opens and releases the pressure so as to prevent the explosion.
- How does the LED flashlight determine the intensity of illumination?
- LED flashlight and flashlight flashlight is the biggest difference is that there is no light, flashlight power and distance, but lighter than flashlight, low energy consumption, use a long time.
- 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).
