2. The LED driver. 
The LED driver plays a very important part of the LED tube product. It can heavily affect the lifetime of the finished product. Due to the different circuit schematics, the cost of the drivers varies greatly. It is applied to change the input AC or DC to DC power to drive the LED chips. This mode can be achieved in three ways, namely, non-isolated linear mode, non-isolated switch mode and isolated switch-mode.

The non-isolated linear mode is cheap, but has some disadvantages. It puts an LED bulb product at high security risk with poor reliability. The worst is that its working efficiency is low, and cannot maximize the energy-saving ljusskyltar led purpose. The non-isolated switch mode of the LED driver costs relatively low. It works with great efficiency and it is highly reliable when delivering the light. However, this mode is still at high security risk. The isolated switch mode is the perfect mode for a driver, as it at low security risk. This mode can work in great efficiency and reliability when delivering the light. The only disadvantage is that the cost is very high.
