Led lamp have drive, don't drive, what's the difference?
The drive is known as the power supply General because leds are mostly of dc power supply Because we use the mains voltage is 220 transformer rectifier Drive is actually a power supply with mobile phone charger is a reason Of course also don't have to drive That is connected to a dc voltage The key is in your family or the place of dc with respect to ok As for the white or yellow light on the effect of the you asked for
In theory does not need to drive, direct input 220 v LED lamps and lanterns of longer life, but at the moment, the corresponding technology is still not perfect, than higher prices, there are still some problems So now can still need to drive leds You want to know what LED lights
Don't have to drive LED lamps and lanterns, the choice of the LED will be similar to Seoul, South Korea, 220 v LED semiconductor, there is no drive LED lamps and lanterns is non-conforming
Is the drive transformer, a normal voltage is 220 v, if the led is not 220 v with drive, yellow light, like the white light that is about to see yourself
