Why does LED fluorescent lamp need not have ballast
- Aug 03, 2018 -

Because the light-emitting principle of LED is completely different from the fluorescent lamp, the purpose of electronic ballast is to be used to upgrade the power supply voltage is high to penetrate the inert gas in the fluorescent lamp so as to glow, so for the fluorescent lamp it belongs to the negative resistance characteristics of components, and led belongs to semiconductor components, as long as the power supply voltage to its working voltage can work, There is no need for that high voltage. and the fluorescent lamp is the AC device, and the LED belongs to the DC device, is two completely different components. Led in the AC circuit used in need of rectification and voltage regulator circuit, so led fluorescent lamp does not need.
