Furthermore, in addition to improving the efficiency and the convenience of the LED lamp, when the LED lamp is produced and assembled, the assembly procedure is simplified and the assembly efficiency is improved. Furthermore, modular production of the clamping board provides more flexibility and function transformation. The LED lamp disclosed by the present invention has a unique way of heat dissipation, which can effectively discharge the heat from the power supply directly out of the lamp, thereby effectively reducing the heat deposition in a lamp body and prolonging the service life of the lamp. 
     The LED lamp in the present invention can eliminate the abnormal sound generated when the lamp body moves by means of the arrangement of the wires, thereby reducing the risks of drop, wear and breakage of the wires. After modular design, each module of the LED lamp can be directly used for separate sale, and modular after-sales services are realized. 
     The above disclosed content is just one preferred embodiment in the embodiments of the present invention and is certainly not intended to define the scope of rights of the present invention.
