What's the difference between a LED light source and a LED light?

Answer:

Incidentally add, energy-saving lamp external voltage is AC 220V, but its operating voltage is much lower in the first internal rectifier buck rectifier DC becomes lower, and then transform into high frequency alternating current drive tube, the external 220V alternating current, is entirely for daily use the convenient, because in China, household power supply is 220V AC.
LED uses semiconductor material to make light emitting diode, which converts electric energy into light energy directly. It has high electro-optical efficiency.The basic working principle of energy-saving lamps and fluorescent lamps are the same, just put into electronic ballast and lamp are made into a whole, while energy efficient than incandescent lamp, but the ratio of LED conversion efficiency to be low, the service life of the tube is not as LED.
