The structure is simple, the cost is low, the input is not isolated program, has the security hidden trouble. The conversion efficiency is very low, and constant current control cannot be achieved. Isolated flyback circuit, the flyback circuit is used to generate the dc level through the transformer on the side side, and then feedback the ripple of this level back to the original side through optocoupler, so as to self-excitation stability.

Some bad manufacturers are driven by inferior rectifier circuits, which will cause the actual energy consumption of LED bulbs to be far higher than that of energy-saving lamps or even close to the level of incandescent lamps. The market has found some brands of 3W energy-saving lamps, the use of 220V power supply input current up to 90mA (19.8W).

COB and IMD technology have their own advantages. Although COB has a high packaging cost, it reduces the weight of traditional solidification process and can be developed in the direction of thin and light. However, entering the COB business requires a company to repurchase equipment and production lines, which requires a firm to have a strong financial position. IMD technology can use SMD equipment, production lines and personnel experience.
