1. I bought the LED tube light, there is some light is driven with constant current, while the input voltage is 220 v, but tend to be low voltage dc output voltage, there are some inserts the 220 v can directly, didn't see any of the constant current drive, so is built into the still say there are two kinds of LED tube light, is a kind of the working voltage of the dc low voltage, a kind of ac 220 v. 2. About the LED tube light, dimmer, I already according to one of the LED constant current drive found the corresponding LED light, that if I was the LED directly to the adjustable light can directly replace the LED constant current drive.
LED lamp bead are dc low voltage, single grain lamp bead generally around 3.3 v voltage can light up, general household LED light has many grain of lamp bead, most of them are in series, no matter which kind of LED lighting needs to be in the form of a voltage conversion device, the voltage conversion device also has a built-in external, have stable manifold has regulated form, useful integrated circuit do useful discrete component, with complex circuit has simple circuit, there are lights and conversion circuit package together also have lights and conversion circuit of separate, anyway is multifarious, various countries now also does not have a specification, each manufacturer yourself, just do what want to make it, so they bring inconvenience to the user, so the home LED light damage, it is difficult to buy the same, every time in the lamp will also ask professional to listen to, you say the problem is not surprising, is likely to be a built-in driver, another oneself need plus drive without a driver.
Do you want to light is adjustable brightness or light color? If it is a variable degree of directly replace driver IC is ok, if is the color temperature of the lamp bead can not suitable for you. 3. Your driver output voltage and current, the series multiple lamp after share current, light can't take much more
Domestic outfit LED tube lights are currently on the market is 12-24 dc drive, just have a plenty of built-in drivers, connected directly to the 220 v power supply, have a plenty of needs to cooperate with the power supply. As long as the light is 12-24 220 v input output can do out of driving
