In any case, the greater the power and brightness of the LED or its module, the greater the heat generated, and it is difficult to dissipate in a relatively small volume of a light-emitting diode lamp. Therefore, the light-emitting diode still has a large heat-dissipation technology bottleneck, and this is also the most difficult breakthrough in the marketization of high-power, high-brightness light-emitting diode lamps.

Therefore, in order to meet the heat dissipation requirements of high-power, high-brightness LED lamps so that they can prevent light decay, it is necessary to provide a heat sink with a large heat dissipation area. This usually results in the heat sink in the luminaire. The volume of the overall ampere is also large, making the luminaire structure larger and difficult to promote in indoor lighting. In addition, since the light-emitting diodes have a certain illumination angle, the light-emitting diodes are illuminated in the light-emitting diodes: the polar bodies are usually arranged on a flat circuit board, and 200923258 makes the illumination area of the lamps limited, in many cases It is difficult to satisfy the user.

The outer wall of the cylinder 22 extends a plurality of heat conducting arms 26 along the radial direction thereof. The heat conducting arms 26 are evenly distributed with respect to the center line of the cylinder 22. The number of the heat conducting arms is corresponding to the body 4 The number of the pole body modules 30 can be different in different embodiments, and in this embodiment, the six body modules 4 ... the heat conducting arms 26 . The heat conducting arms 26 extend from the central axis of the cylinder 22, and the heat conducting arms 26 extend perpendicularly from opposite sides thereof to the outer fins 260, and each of the outer fins 260 is symmetric about the corresponding heat conduction 26 and The length of the outer fin 260 gradually increases from the inside to the outside. The end of each of the heat conducting arms 26 is connected to the inner surface of the fins 26〇 of the outermost end. Therefore, the outermost surface of each of the heat conducting arms 26 is a smooth plane on the outer side surface of the outer fin 260. The bottom end of the tubular body 22 extends downwardly to form an extension cylinder 28'.

Each body 40 has a shape of a shape, and its height gradually increases from bottom to top. Each body 40 includes an inner panel 42 , an outer panel . 43 , and a plurality of connecting panels 44 connecting the inner panel 42 and the outer panel 43 . The inner panel 42 is attached to the outermost outer fins 260 of the first heat sink 20, and is exactly the same size as the smooth outer surface of the outermost one of the outer fins 260 so as to coincide. The outer panel 43 is formed to extend obliquely upward from the bottom of the inner panel 42, and the distance between the outer panel 43 and the inner panel 42 gradually increases from bottom to top. The plurality of connecting plates 44 are horizontally connected between the inner panel 42 and the outer panel 43, and the length of the connecting panel 44 is also gradually increased from the bottom to the top. A flow path 45 through which the airflow passes is formed between the adjacent two connecting plates 44. The LED module 30 includes a rectangular circuit board 32 that is sized to correspond to the outer panel 43 of the body 40.
