Light source subassembly 4 is the aluminium base board of taking the lamp pearl, fixes on radiator 7 through lamp plate screw 3 to utilize heat conduction silicone grease to optimize the contact between the two in order to do benefit to the heat dissipation. The central position of the aluminum substrate is provided with a hole to avoid a locking nut 5 of the radiator and a sealing ring 6 of the end connecting rod of the radiator. The optical component 1 and the radiator 7 of the lamp body are directly assembled, the assembly structure is a thread or other structures, a lampshade sealing ring 2 is arranged between the optical component 1 and the radiator 7, and the lamp body is placed at the joint of the optical component 1 and the radiator 7 and is favorable for water prevention. The radiator 7 is disc-shaped, and vertically surrounding strip streamline radiating fins are arranged on the periphery of the radiator, so that the radiating fins in the shape are beneficial to increasing the radiating area and improving the radiating efficiency. The radiating fins are designed into long strips, so that the length is increased, the distance between the driving part and the light-emitting part is increased, and possible mutual interference influence, such as mutual electromagnetic interference or mutual influence of volatile components generated when being heated, is eliminated. The center of the disc-shaped radiator 7 is provided with a through hole, one end of the central connecting rod 8 is connected with the radiator 7 through the through hole by a bolt, and the central connecting rod 8 is positioned at the center of the radiating fin of the radiator 7 after the assembly is finished. The shape of the central connecting rod 8 is designed to be regular hexagon, and the non-circular section shape is beneficial to tool clamping and stress during assembly, so that the connecting rod does not adopt a circular section in the shape if necessary, and both ends of the connecting rod are provided with external threads. The inside of the central link 8 is a hollow rod sized to pass the wire smoothly. The power line led out from the driving assembly 14 penetrates through the cavity via the inside of the central connecting rod 8, penetrates out from one end of the light source assembly and is connected to the welding disc of the aluminum substrate. The central connecting rod 8 is made of extruded aluminum profile made of metal to ensure sufficient mechanical strength.
