Q:How to maintenance of led desk lamp filled in no electricity

Possible battery charging circuit is broken, seeing you is what buck circuit, if it is a transformer or resistance and capacitance step-down circuit is relatively simple, maintenance is a electronic components, slightly understand electronic knowledge can repair myself. If it is switch power supply is trouble to repair, to professional maintenance technology to repair.

Q:Led lights can use how long

This LED lamp bead and heat dissipation And processing technology. Do good can reach 80000 hours Even 100000 hours. Finished the test last week Accelerated aging 3000 hours A 25% drop in flux.

Q:Baby what kind of table lamp? The LED lamp can be eye really?

Not so fantastic is LED light switch frequency very fast, because mostly constant current power supply, so stroboscopic barely see, eyes can't feel you anyway. So in the eye. The main electricity savings, because is the fourth generation of light source, photoelectric conversion efficiency is higher than the first generation of the candle to the heaven. As the downstairs said, the equivalent of 13 w 5 w energy-saving lamps, 40 w incandescent lamp. Even more playing god.

0.5 A, you said is refers to the input current, voltage requirements of the charger? USB port is 5 v? If 5 v, you don't have ability to pipe the output of the charger is 0.5 A or 1 A, 2 A, 10. A, as long as the voltage is consistent, you can rest assured, when the charger voltage is 5 v, 0.5 A, 1 A, 2 A, 10 A... Refers to the charger output ability, such as 5 v2a charger, its output ability is strong, can recharge four 0.5 A LED lights at the same time, also can at the same time for the two 5 v 1 A cell phone charge.

Q:Charging forgot to turn off the switch, directly inserted, and then not bright,, but the charge will bright lights.. Bulb burned out or what? Can you take?

Now small home appliance products, such as LED lamp manufacturer in order to save costs, the internal circuit is very simple, direct is the way of resistance capacitance charging circuit, and probably doesn't even have the battery charge over discharge protection, quality is not guaranteed.

Q:LED rechargeable lamp charging is better
