Description of the Invention: [Technical Field] The present invention relates to a light-emitting diode, and more particularly to a light-emitting diode having a high heat dissipation efficiency. [Prior Art] It is generally considered that the light-emitting diode has the advantages of low power consumption, low heat, and long life, but it does not refer to all the light-emitting diodes. When using a low-power light-emitting diode, the amount of heat generated can be naturally dissipated in a normal use environment, and the problem caused by poor heat dissipation is not caused. However, when a high-power light-emitting diode is used, the efficiency of natural emission is inferior to the large amount of heat generated during operation, so that it is particularly prone to failure or shortened service life due to accumulated heat. In order to solve the above situation, there is a design for dissipating heat for a high-power light-emitting diode. Please refer to the ninth figure for a schematic diagram of the use of a heat-dissipating high-power light-emitting diode. It includes a high power light emitting diode component (80), a heat sink block (91), and a heat sink fin set (92). The high-power light-emitting diode element (80) has a pedestal (81) and a high-power light-emitting diode chip (82) provided on the susceptor (81) and covered with a resin or the like. . In order to enhance the heat dissipation efficiency, the susceptor (81) is disposed on the heat dissipation block (91), and the heat dissipation block (91) is disposed on the heat dissipation fin group (92). In a typical embodiment, the heat sink block (91) has a surface area that is much larger than the base (81). The heat generated by the high-power LED chip (82) during operation can be conducted through the pedestal (81) to the aforementioned 4 1 336 967 heat sink block (91) and then dissipated through the heat sink block (91). While the heat sink block (91) dissipates heat, its heat is also transmitted to the heat sinking group (92)', and the heat sink fin group (92) provides a larger surface area for heat dissipation. However, the heat dissipating block (91) and the heat dissipating fin group (92) are radiated by the technical means of expanding the heat dissipating area, so that the heat dissipating effect is rather limited. On the other hand, since the heat dissipation effect relies on the enlarged heat dissipation area, when a plurality of high-power light-emitting diode elements (80) are used in combination, the required heat sink area is expanded to be unacceptable to be practically used. To the point. In addition, when the heat is dissipated, the air flows passively and turbulently between the heat radiating fin groups (92), and the air cooling effect is greatly reduced. SUMMARY OF THE INVENTION The present invention is directed to providing a heat-dissipating light-emitting diode having a heat-dissipating light-emitting diode that is enhanced by air convection. The heat dissipation effect and the advantage of a small front end area.

In addition, the outer surface or the surface of the official wall exerts the effect of dissipating heat, and the aforementioned air is more effectively enhanced by the chimney effect of the chimney effect. ... On the other hand, the system of the official system extends from front to back, so that the area occupied by the front end of the tube is only a small proportion compared with the area of the tube body. That is to say, the heat-dissipating light-emitting diode of the present invention has a small positive surface area. When a plurality of heat-dissipating light-emitting diodes are arranged in parallel, the heat-dissipating light-emitting diodes can be closely arranged and closely arranged.
