Specifically, the power line terminals capable of being plugged in are attached to the power driving part 10 and the light source board 20, one end of the power line is inserted into the terminal of the power driving part 10 in the front, and then the other end of the power line is inserted into the terminal of the light source board 20 in the back, so that the power driving part 10 is electrically connected with the light source board 20. In addition, a terminal for back-plugging a power line is attached to the power driving member 10, the power line is back-plugged to extend to the top of the structural member, and the lamp cap 50 fixes the power line on the structural member in a riveting manner, so that the lamp cap 50 is electrically connected with the power driving member 10. However, the power driver 10 is made of glass fiber board, so that the whole power driver 10 has poor heat conduction effect, and cannot quickly conduct heat to the heat sink 30 for heat dissipation. Therefore, it is conventional practice to conduct the heat of the power driver 10 to the heat sink 30 by potting. This not only increases the cost of the entire lamp, but also has production contamination that needs to be addressed by glue removal.
