How to help LED fluorescent tubes to better dissipate heat

LED fluorescent tubes on the market today generally do not have heat sinks. Such lamps cannot achieve high power, high quality and long life.
The correct product design should consider the heat sink together. The industrial production is to use the heat sink of the LED fluorescent tube to extrude the semi-circular finned aluminum profile with a mold, and then cut the required length according to the power, and then make Take out the aluminum-based copper foil line, fix the chip on the copper foil, connect the gold wire or use the helper. Such a lamp has a good heat dissipation effect, and has only two thermal resistances, one or two thermal resistances less than the conventional packaging method, which effectively reduces the temperature of the chip, and can play a role in improving the quality and life of the LED fluorescent tube.
Another method is to design a rib on the aluminum profile, and mill out a number of rectangles according to the need, and use the ordinary (0.8-1.0mm thick) pcb circuit board to open the square hole in the rectangular shape of the aluminum profile, and paste the pcb circuit board or Riveted on the aluminum profile, the LED chip is fixed on the rectangular ledge on the aluminum profile, and the wire on the PCB is connected to the chip by the gold wire. This kind of production process is the best, only one heat resistance, the best heat dissipation effect, manufacturers of LED lamps should give priority to this solution, followed by the method of making copper foil lines on aluminum profiles. Only such innovation can effectively solve the heat dissipation problem of LED long strip lamps, and also improve the quality and life of LED fluorescent tubes.
