Problems solved by technology
[0002] LEDs have begun to be popularized in indoor home lighting applications, but outdoor lighting has not been widely promoted due to limitations in the technical level and cost of lamp structures.
[0003] The structure of the lamp is mainly composed of the lamp body, the heat sink installed on the lamp body, the light source and the driving power supply. Among them, the heat dissipation performance is particularly important, which directly affects the life of the light source and power supply. Therefore, we see that the heat dissipation of lamps, such as street lamps The radiator is extremely bulky and takes up a huge space on the lamp body. Only such a large-volume radiator can meet the heat dissipation requirements, but at the same time, the cost of this radiator is high. The reason is that The structural design of the radiator has not been reasonably planned. From the radiators on the market, we can see that the structure of the radiator is arranged in the same strip shape with equal intervals. This structure has a small heat dissipation area and large wind resistance of the heat dissipation fins. , can’t get rid of the shackles of increasing the volume and materials to improve heat dissipation; on the other hand, the cooperation between the radiator, the light source, and the power supply is only a simple contact heat conduction, and no effective heat dissipation design is made from the structure. The reason for the high cost

Embodiment Construction
[0031] Such as figure 1 As shown, it is a heat sink of the present invention, including a heat dissipation chassis 10 and a first heat dissipation fin group 20, a second heat dissipation fin group 30 integrally formed (such as a stretching process) on the heat dissipation chassis 10, and a first heat dissipation fin group 30. The heat dissipation fin group 20 and the second heat dissipation fin group 30 are arranged axially symmetrically with the central line of the heat dissipation chassis 10 as the axis of symmetry, and the heat dissipation fins of the first heat dissipation fin group 20 and the second heat dissipation fin group 30 are both Arranged at intervals, the heat dissipation fins of the first heat dissipation fin set 20 and the second heat dissipation fin set 30 are curved in an arc shape toward each other.
[0032] This kind of arc-shaped and curved cooling fin is bionic design, extracting the "chrysanthemum" modeling element, breaking through the previous straight...
