FAQ

What are the driving IC used in LED bulb?
MT7930, LM3445MM do bulb bulb, the effect is also ok.
Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!
You are not the light source, in addition to a treasure bully ordinary consumers can't tell the difference between good and poor light source, all blow themselves jingyuan. I think you can see for yourself, not necessarily expensive or cheap but wafer, it certainly can not be said. Big power of a simple 1W bar, poor beads 1-3 cents, the wafer will be 1.3-2 dollars. There are several tiles, and how much does it cost?.
I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
It's possible to assemble your own bulb. The power used in the bulb is too large. It causes the gold wire to burn
LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
There are several good LED ball bubble, which with aluminum cooling. Relatively new appearance.
Are there any differences between negative ion bulb and LED bulb?
LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.
Want to find common features, unified purchase accessories repair!
The proposed open, lamp is broken, can find light black or other unusual circumstances, bad power supply at the circuit board and components have the same burn what, under normal circumstances is such.
What advantages does LED bulb replace energy saving lamp?
The response time is fast, the energy saving lamp is millisecond, and the LED light is nanosecond
LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
