Description of the Invention: [Technical Field of the Invention] The present invention claims a Korean Patent No. 10-2010-0113704, 10-2010-0113705, 10-2010-0113706, which is filed on November 16, 2010. Priority. This is incorporated herein by reference. The present invention relates to a heat sink for a light emitting diode (aED lamp). More specifically, it relates to a heat sink for a light emitting diode lamp, in which a separate heat sink fin (heat -dissipating fins) can be surfaced to one of the radiators to increase the heat transfer area while maintaining a stable support, while the heat sink is also kept lightweight. [Prior Art] A light-emitting diode lamp is used as a light source in which an LE:D wafer is incorporated; recently, an LED package in which a rain-efficient LED chip is incorporated is widely used to obtain an ideal light-emitting effect. Such LED packages are used in various fields such as indoor/outdoor lighting, vehicle headlights, and backlight units used in liquid crystal displays (LCDs). Therefore, the LED package needs to have both high efficiency and high heat dissipation. In particular, a light-emitting diode lamp is used indoors and outdoors for a long time. In this case, if the heat generated in the LED chip cannot be effectively dissipated through the entire 201224352 package, the temperature of the LED chip will rise. High, this situation will destroy the LED chip and shorten its manufacturing life. Therefore, the heat dissipation structure is a very important factor for flowing a large amount of current in a light-emitting diode lamp. FIG. 1 is a perspective view of a conventional light-emitting diode lamp. In a commonly used luminaire, a screw-coupled socket 3Q is disposed at a lower end of the illuminating diode lamp, and an LED chip arrangement 10 is disposed on the illuminating diode 2 One of the pole lamps is the upper part. A heat sink 20 is disposed in a body of the light-emitting diode lamp in a position between the upper end and the lower end. The heat sink 20 is formed on an outer peripheral surface of one of the bodies to have a wing-like shape and serves as a passage for forming air and discharging heat energy. The arrows shown on the right side of the figure represent the channels for discharging thermal energy. That is, the heat sink 20 is for discharging the heat energy generated from the upper end portion thereof to the lower side thereof in a circumferential direction. FIG. 2 is a perspective view of a heat sink 20. The heat sink 20 has a plurality of fins 22 (lengths) protruding in a longitudinal direction; and a cylindrical body 21. As shown in Fig. 2, in the prior art, the heat sink 20 is made of aluminum by die casting to dissipate the heat of the light-emitting diode lamp. The LED chip 201224352 disposed on a printed circuit board (PCB) is a heat source, and the heat generated by the heat source is conducted through the heat sink 2〇. The 'flap 22' is then composed to make the contact area of the heat sink 2 turns larger. However, the body 21 of the heat sink 20 is integrally formed with the fins 22, and is made of a thick metal by die casting, which is heavy in weight and whose expansion of the contact area with air is limited. Therefore, the heat generated is more and more large, but the heat dissipation capability of the conventional heat sink has its limitation, and when the weight of the heat sink increases, there is a risk of occurrence of a safety accident. SUMMARY OF THE INVENTION [Technical Problem to be Solved] The aspect of the present invention is to provide a heat sink for a luminaire that has a separate heat sink fin-connection structure for making a lighter weight and a larger Thermal conductivity and higher heat dissipation efficiency. Another aspect of the present invention is to provide a heat sink that faces the illuminating illuminator, wherein the fins are maintained at a distance to provide excellent secrets and a simple assembly process.

Accordingly, since the heat sink body and the heat dissipating fins are coupled to each other, the overall weight of the heat sink can be alleviated and the heat dissipation efficiency can be improved. According to another embodiment of the present invention, the heat sink system includes: a cylindrical heat dissipation base; and a cap-shaped heat dissipation top cover, which is connected to the upper side of the reduction seat. According to this, the heat dissipation and fins can be easily and stably combined. According to another embodiment of the present invention, the heat dissipation base includes: a cylindrical body to be opposite to the scattered outer table; the shaft protrudes to the upper side of the body, and the lower branch In the flap, the outer peripheral direction of the n is extended from the upper end of the body. According to this, the heat dissipating fin can be stably supported and the heat transfer area can be enlarged. According to another embodiment of the present invention, the cover is attached to an upper end of the coupling shaft, and the upper end of the heat dissipation fin is inserted and fixed in the heat dissipation cover, and the heat dissipation cover includes a lower recess formed in a lower portion of the heat dissipation top cover as an annular space for accommodating the insertion and fixing of the upper end. According to this, the upper side of the heat dissipating fin can be inserted into the upper side to further support the surrounding area and increase the heat transfer area thereof. According to the present invention, the junction (4) has a cylindrical shape with a diameter smaller than the diameter of the body. According to another embodiment of the present invention, an annular space is formed on one of the outer peripheral edges of the connecting shaft, and the air is inserted into the annular space, and the body is continuously connected. Accordingly, the age of the heat sink fins can be further increased, and the heat transfer area can also be enlarged. 201224352 According to another embodiment of the present invention, a ring-shaped support groove for supporting the lower end of the heat dissipation fin is formed in the lower support portion. According to this, the lower end of the heat dissipating fin can be stably supported. According to another embodiment of the present invention, the heat dissipation base further includes: a step for grasping and fixing the heat dissipation fin, and projecting upward from an outer periphery of an upper end of the body. According to this, the lower side of the heat dissipation fin can be stably supported. According to another embodiment of the present invention, the heat dissipation fins each include: a fin-shaped fin portion having an inner edge in contact with an outer peripheral surface of the body; and a lower insertion portion supported by the lower support portion And an upper insertion portion that is inserted into the lower portion of the heat dissipation top cover. Accordingly, the heat dissipating fins can form a secret portion coupled to the heat sink body, and the heat dissipating fins can be accurately aligned to enhance coupling reliability. According to another embodiment of the present invention, the heat dissipating fins further include: a contact portion 'which is formed by bending the inner peripheral edge g of the fin portion and contacting an outer peripheral surface of the body to form . According to this, the heat transfer area can be enlarged. The heat dissipating fins are reliably circumferentially disposed. According to another embodiment of the present invention, a holding recess is formed, each of the heat dissipating fins further comprising: a grip formed on an inner circumference of the fin portion and the upper portion
