Q:My desk lamp is touch switch, led lights are lit, touch switch to the touch is not working, has been bright, the luminosity is very dark now, not so dark before, but also it can be used to adjust luminosity, now touch switch has no effect. Hope the master directions... Please!!!!!!

May be integrated block voltage is insufficient, low voltage cause, if you know some measure voltage circuit lo is not normal!

Q:Why my desk lamp light will keep the cell phone camera shows and white flashing light and shade stripes

To the naked eye for frequency fast things cannot be directly observed. Such as mosquito flap wings we cannot directly observe. Mobile phone camera is more than 25 frames per second picture taken, so we can see

Q:LED small desk lamp, found that the charging indicator light is not bright, or bad?

You put the electric light, and then filling, can see light, not just can not charge the electricity, if can light is the light is broken, and there's some light charging is not bright, full of bright, look ok

Q:Long card LED charging small desk lamp

Question 1, exactly how long is the charge? Ha ha, write on the package for 8 hours to eight hours filling bai, without packing on the accurate online said. In my experience to tell you, 6-10 hours can, usually about filling. Actually charge much less charge will only affect the service life of lead sulfate in lamp battery, lead acid battery is made of memory effect, its charge number is directly related to its service life, so full of as well. But don't forget to pull out 24 hours, so there will be no safety accidents. 2, charge how many hours to charge, charge is not enough time to influence? Already answered above, will only affect the life. Influence is very big. Suggest you fill 8 hours as well.

Q:Card lamp, LED desk lamp can take a plane

Card lamp, LED desk lamp can take on the plane Articles carried by plane Total on domestic flights, each person can carry no more than one litre of liquid items, and shall open a bottle of check, certainly can carry. Beyond the parts must be shipped. Alcohol items must be checked.

Q:I had had a 20 leds rechargeable lamp, then search the battery is broken, I version removed yourself to make the lamp, can directly use electrical appliances, please start

The desk lamp of you already can charge (should be 220 v) you can directly with charging power supply should be bright?

Q:How many watts of LED3 is equal to the ordinary energy-saving lamps

3 w leds is equivalent to 3 w of energy-saving lamps, not so simple than power depends on photosynthetic efficiency, luminous flux and color rendering, the quality of the different products are not the same as the 4 w energy-saving lamps can replace 20 w energy-saving lamps, good product can substitute for 35 w halogen lamp cup LED is also in the same way, the 3 w can also reached the standard of 15 w incandescent lamp, lighting is not suitable for lighting

Q:The LED lamp is bad for your eyesight?

Q:Desk lamp battery charging why not directly connected light emitting leds, but to a diode, the diode have what effect

See what the battery, the normal pressure drop of white LED is controlled in 2.8 3.6 V, if use lithium battery 3.7 V voltage is a little high, if he does not limit current will be very big, LED immediately to turn the raw materials.

Q:Folding LED touch lamp generally will be problematic

Is the most prone to problem of LED lights, light failure after the time far short of the publicity of use fixed number of year. Followed by touch components, due to the aging over time, after a certain period of time, the original set of voltage and current value has been far away from the original design value, prone to touch difficult, the problem of interval are not allowed to touch.
