Q:The LED lamp how to realize the function of adjustable brightness and color temperature?: Simple dimming can be concatenated in the LED lamp bead loop resistance, change the current, can adjust the brightness, better with adjustable brightness of PWM pulse width adjustment, circuit is more complex. Color temperature seems to be no commonly, by LED lamp bead characteristics (fixed) materials and manufacturing has decided, unable to adjust.

Q:The LED fluorescent lamp color temperature probably how many is the best: In addition, need different environment illumination light color is also different. The household environment, for example, if the sitting room with warm white lighting, can appear dark, stuffy, narrow space; Bedroom, bathroom with cold white light, can appear cold and stiff and lack of emotional appeal again.

Q:Long amount of brand of LED desk lamp capacitor charging Fried v100uf 50: This kind of LED desk lamp, 220 v power supply is to step down by means of capacitance current limit, 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 failure, you must first check whether the no-load and load of power supply circuit is normal battery, check the battery cables are broken, the charging current limiting resistor is burned, if these are no problem to check current limiting capacitance itself isn't breakdown (usually the breakdown causes 220 v over-current, empty trip meeting).

Q:Heard that LED save electricity, to follow the fashion, a grind, spent more than three hundred bought 6 LED bulbs, but less than 3 months finished bad, all manufacturers attitude can also, all changed, but also bad, depressed.: You buy the LED is very low.

Q:Small leds, charging when hear the sound of the PI PI is what circumstance?: There is a virtual place leakage or unstable power supply contact, don't take place contact line virtual to real, it is easy to burn out.

Q:How many good study led desk lamp: What do you mean how many degrees? Power? Brightness? Intensity of illumination? The temperature?With 3-5 w power leds.

Q:Could you tell me how to repair have been flashing led desk lamp open,?: Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.

Q:22 what is the power of the led lamp charging desk lamp v: Do you want the output voltage or input What's going on?I hope you can help me.
