Now the use of LED bulbs is very common, but if some of the broken first do not rush to throw away, open the change may be able to regain a new life. Here is how to use a broken light bulb to mobile power to use it.

First, the light bulb open.

Next, use a soldering iron to solder down the original bad circuit board. (Tip, some lights are bad for a particular lamp bead becomes black, as long as the direct shorting will be repaired, yo!)

Then re-weld the DC-powered LED lights inside, cover the good lampshade. (Knowing the circuit can directly use the original light it)

After that, then cut a data cable to the two poles of the bulb solder, pay attention to the positive and negative polarity to. Let it connect the other end to the USB port.

After the completion of the other end connected to mobile power, chargers, etc. can be used for lighting. Is not very good.
