Q: LED rechargeable lamp charging is better: Close the lamp light source recharge, long time need not when please charge once 3 months, and is to reduce the battery life would be!

Q: Led lights can use how long: 100000 hours are brag, capacitance is short of this life, about 30000 hours

Q: What is the battery charging led lamps use: We talk about the LED bulbs for first, namely light-emitting diodes (leds), the working voltage of it around 1 v, current dozens of ma can light it, this is also the characteristics of it can save electricity, because the LED working voltage is very low, if you wait until dark light bulb, it shows that the battery has been severely deficient electric (that's Achilles' heel of the battery). And as the power of its work the most time is also hundreds of ma maintenance-free lead-acid battery, you should say ten dollars, it is this), if is lead-acid batteries, will be added in time, only under the condition of the battery voltage and current saturated plate vulcanizing speed of the slowest, keep up with a three to five years is no problem. If your battery is lithium electricity or nickel, head a few times when the electricity again after filling completely (this is to activate the various chemicals inside), the time is 15 hours (around 500 ma charger) the following 14 hours, in use process (charger during normal use 200-300 ma, charging time of 8 hours) it is best not to let it lose the electricity charge again, li-ion battery and nickel electric prone to memory, long battery capacity will be more and more small, the last rush is full, one with no phenomenon, that is the life of the battery the end of the walk.

Q: The led lamp low-grade why current sound: LED lamp, can use dc power supply, high frequency switching power supply, constant current drive power supply, can also use the 50 hz inductive step-down transformer rectifier power supply.

Q: Elementary school students with what kind of table lamp is the best? The LED lamp?: From the perspective of the characteristics of the LED light source which has: no stroboscopic (traditional lamps and lanterns is constantly flickering just frequency are thought not to come out, this is a big damage for eyes) with the effect of eye protection, no pollution, long life, environmental protection, etc.; So it is recommended to use the LED desk lamp, but pay more attention when the choice, now LED market is chaotic quality time not neat, so when the choice is to pay more attention to the strength of LED desk lamp seller to ensure his quality and after-sale, 2 it is to see the buyer on his evaluation, 3 it is to see a few with power LED lamp price, the price is too low, not to buy. The hope can help you

Q: How long will leds last?: Absolute durable, more durable than bulb or tube had, but are you going to buy factory goods, don't look at somebody else's expensive, but it is good, no matter the luminance or life is good.

Q: Low voltage LED desk lamp belongs to the scope of 3 c certification: Low voltage LED lamp -- -- -- -- -- is 220 v electricity, or the battery? Pick up the 220 v power will have to do the CCC certification

Q: The LED lamp can change the light bulb: Can, but want to use soldering iron, more troublesome, generally in all the places selling electronic components.

Q: Why my desk lamp light will keep the cell phone camera shows and white flashing light and shade stripes: Mobile phone in the low frequency of light is there will be a ripple, over a period of time.

Q: Desk lamp good still tube of good to buy LED strips? Search light tube usually can use a few years need to change?: A low power consumption and lower power LED that LED the working voltage of is generally 2-3.6 V. The working current of 0.02-0.03 - A. That is to say: it consumes the electricity is not more than 0.1 W. 5, green environmental protection, high efficiency and energy saving, the LED is made from non-toxic material, unlike fluorescent mercury can cause pollution, at the same time, the LED can also be reused.
