Q:The LED current problem? LED lamp current problem?
USB interface receive computer desk lamp, computer burden is heavy, easy to addled computer. Besides, desk lamp, desk lamp, 1 a current lamp current 190 ma, bad, or move a few desk lamp table lamp lights die.
Q:Small leds, charging when hear the sound of the PI PI is what circumstance?
Is generally small damage to the battery, electric charge not sparking discharge into the battery internal crack formation. If power cuts back light can light, such as the residual power after use, there is no next time. Change the battery available in theory, but the lamp was selling point is cheap, no place to repair; Oneself know words, not expensive for a few dollars online battery, can add the postage is not cheap.
Q:Household led lights all of a sudden not bright? What's the matter?
If it is suddenly not very bright, usually because of its heart - LED drive power quality problems, the result of current is not enough. You can open it and have a look at the LED string, and power, to find a professional power supply company with power supply, diy connected the input and output line. If the trouble is returned to the manufacturer maintenance, this problem should be something for manufacturers. If it is used with the not so bright, like how did not suddenly don't bright, quality problem is LED lamp bead, light failure is too big. If a lamp is on there are a lot of small lights bead is unlikely this case maintenance, cost and the cost is too big, can only be changed directly. If it is only a high-power lamp bead and COB encapsulation of LED, don't bother you also can buy back to transfer the lamp bead.
Q:The led lamp low-grade why current sound
The 12 v power supply meet the led light have the cause of the current sound is due to your power supply is provided by the 50 hz ac, and 50 hz transformers, and loose core. If it is a high frequency switching power supply, or dc power supply, is listening to less than 50 hz hum.
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:Led lights can use how long
Leds are not only have the characteristics of energy conservation and environmental protection, as well as long service life, general use 10 to 20 years.
Q:Three lights in parallel, and should be how the resistance of the step-down series?
What is your 6 v battery batteries? Small battery (battery)? 10 v charger to see what the battery charger, if the battery can work with, if nimh electricity or lithium electricity will reduce the voltage. How much is the pressure light bulb? It is best to parallel, serial word broke a are not lit up. Add how much resistance depends on what you use the lamp, or led. The dimming added potentiator current limiting. How to do is very simple, still with the figure? Charger and battery, lamps (and) series of potentiometer. If it is nickel metal hydride batteries can't do, for a long time will seriously affect the battery life in charging status. The more complex.
Q:LED bulbs can put in the desk lamp of adjustable brightness?
Bad,, it will damage the silicon controlled voltage regulator, The desk lamp of adjustable brightness can only answer the incandescent light bulb
Q:Long amount of brand of LED desk lamp capacitor charging Fried v100uf 50
This LED desk lamp, 220 v power supply is to step down by means of capacitance current limiting, once the no-load, after rectification voltage will be increased to 310 v, 220 v x under the square root of 2), seconds kill the capacitance of the withstand voltage 50 v. So, this kind of failure must first check whether the no-load, normally the power circuit of the load is the battery, check the battery cables are broken, the charging current limiting resistor is burned, if these are no problem check current limiting capacitance itself isn't breakdown (usually the breakdown causes 220 v over-current, empty trip meeting).
Q:Could you tell me how to repair have been flashing led desk lamp open,?
Capacitance is no problem, look at the electrolysis have loose, no is the lamp bead has a problem, you can each lamp bead series alone, you won't be the bad of the series in the flashing
