LED fluorescent lamp principle circuit diagram

At present, among various light source products, LED fluorescent lamps have the highest photoelectric conversion efficiency and the longest lifespan. LED fluorescent lamps have four key technologies: safety, LED light source, power supply, and heat dissipation. They are very distinctive products. Although traditional SMD products can connect the positive and negative electrodes through the gold wires of the chip, they also allow the heat energy generated by the chip to be connected to the silver pins through the gold wires. The conduction of heat and electricity is conducted by money, and the accumulation of heat takes a long time. Will directly affect the life of LED fluorescent tubes.

Nowadays, there are new types of LED light sources. The chips are placed on the pins. The heat energy passes through the pins and directly dissipates the heat generated by the chip nodes. It is qualitatively different from traditional direct-plug products and traditional SMD products in terms of heat dissipation. The node temperature of the chip will not accumulate, thus ensuring the good usability of the light source lamp beads, ensuring the long life and low light attenuation of the light source lamp beads. As shown below.
