Linear constant current driver IC is a constant current chip LED lamp. All circuits are nothing more than resistors, capacitors, inductors, and some diodes and transistors.
Constant current is mainly driven by constant current IC. Constant current means constant current. Generally, the input current remains unchanged when the input voltage changes. The constant current driver IC is just an integrated circuit with a constant current signal inside, so that the voltage and current in the circuit are in the same phase on the vector diagram, and neither lead nor lag behind each other.
Extended information:
High-voltage linear constant current uses segmented lighting to drive high-voltage lamp beads, generally using 1 segment, 3 segment, 4 segment, etc., the more segments there are The higher the efficiency. Likewise, the more segments a circuit has, the more complex it will be, which is not conducive to large-scale production.
Most of the large number of bulbs on the market use 1-segment segment drive, with a built-in MOS in the IC to meet indoor low-power lighting needs. While the cost is low, it is very suitable for the production of integrated optical modules and is easy to arrange circuits. However, in a specific environment, when the 220V AC power of the power grid fluctuates, the high-voltage linear electrolysis solution will cause flickering, commonly known as "pressure flash".
