Q:Need to solve the problem of the LED light flashing: Confirm your 12 v charger ac components have? Using the multimeter, exchange files have measure ac voltage, and you want to confirm what you said is the lamp bead board was flashing (that is specialized flashing LED lights with IC control board).

Q:Are LED lights compared to dc lights?: Basically agree with net friend in front of the answer. The desk lamp of ordinary incandescent light bulbs with energy-saving lamps, bulbs and tubes in the current is an alternating current. Incandescent lamp current is ac mains, 50 hz, on and off the 100 times per second. Filament is high temperature heating, heat capacity to a certain extent, to cool and hot, stroboscopic was not obvious, but low light efficiency, energy saving. Energy-saving lamps, is the mains ac rectifier dc, again for the high frequency inverter (several thousand Hz) communication, energy saving, stroboscopic is not obvious, not like a normal fluorescent lamp. LED desk lamp, the energy conservation, but see, on the market at present basically is a built-in battery, use mains charging can't use the lamp, can light up from the mains before, often charging more than 6 hours, often should charge, so if used in a short time is can, such as to use for light continuously over a long period of time, is not convenient. LED flashlight, with short time, it is very good. If there is no battery, do not need to charge, it is more convenient. Above for your reference.

Q:New LED small rechargeable lamps filled with electricity or running: First power consumption, basically see your battery is what material, have the ability to remember. If nickel-chromium batteries will be used up first, then charge, you can't have the to lithium ion.

Q:Led rechargeable lamp, charging is completed, charging indicator light color?: There are two kinds of lamp battery: Lithium battery charge with mobile phone charge, same instructions filled with red light turns green said, such as no charging indicator can only refer to the instructions. Lead-acid batteries used in dozens of pieces of low-grade called students or children desk lamp, rechargeable light most of the products will not change color, usually from a few hours to ten hours. Lead-acid battery charging requirement after filled with a floating time state, with the changed the user capacity and circuit design is difficult to grasp, because charging time short, filling is too long to form a rechargeable battery life shortened, theonly low-grade products without charging protection circuit, only carefully study the product description. Rough judgment: try every half hour after 2 hours filling light observation (do not charge while light), and if no longer increases should be full of light is the brightest and desk lamp brightness, floating charge time same again can

Q:Three months ago I was full of electricity, this three months I was useless, now basic is full of electricity, use need not use a few hours to recharge first? Or direct charge?: Make sure you are li-ion battery or lead acid, lithium electric light and dark are used to also go, lead-acid was at any time, then keep full electricity to save battery.

Q:How to repair the led rechargeable small desk lamp: If the part is not bright, check if not bright LED's virtual welding or burning.

Q:The LED lamp can use while charging?: Quality is better, is to use the constant current source, you can charge while using, quality generally USES is voltage source, charging or not of the lamp voltage constant, can also charge while using. Quality again almost lamps and lanterns, the battery light directly, when charging, with charging part of the road, as long as the battery line voltage is also the normal range, flushed the edge can be used. The worst may be something wrong with the battery, charging circuit directly to the led lamp, so it is easy to burn out the light, it is recommended to use multi-function controller, can control the charging and discharging, ensure the safety of the leds.

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: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?: You said you are a lantern fair due to the charging forgot to turn off the switch, could be greatly batteries have gone bad, try to change the battery.

Q:Buy the LED desk lamp, what should be pay attention to: But the LED lamp bead quality difference is very big, inferior lamp bead to the eyes not only useless, still can damage the eyes. Due to the LED manufacturing process of the core technology or in the hands of big foreign companies, so try to choose imported LED lamp bead, using the lamp that shield an eye is the guarantee of quality of the light source is the most important. The other is the appearance, price and other external factors
