Abstract:
1. A replaceable LED street lamp module, comprising at least one module portion and a clamping sheet set; the module portion comprising: the clamping sheet set comprising at least two clamping sheets, wherein inner edges of the at least two clamping sheets are clamped in the notches of the radiating fins, thereby clamping and fixing at least one module portion, and outer edges of the at least two clamping sheets serve as fixing portions used for locking and fixing a street lamp housing; wherein the total radiation power of the heat pipe set is larger than or equal to the power to be radiated by the LED module; wherein the heat conduction path is as follows; the LED module directly transfers heat to the aluminum nitride ceramic substrate, then directly to the heat pipes, then to the inner radiator, and then lastly to the outer radiator, wherein the aluminum nitride ceramic substrate and the heat pipes are heat conduction media with low thermal resistance.
