Description of the Invention: [Technical Field] The present invention relates to a lighting device, and more particularly to a light-emitting diode lamp. [Prior Art] As a new generation of light source, the light-emitting diode light source can not replace the traditional white weaving lamp on a large scale. However, it has the advantages of long life, energy saving and environmental protection, and is generally marketed. I am optimistic. Moreover, the module composed of the light-emitting diode can generate a high-power, high-brightness light source, so that it will widely and revolutionarily replace the conventional light source such as a conventional incandescent lamp, and thus become the main light source in line with the theme of energy conservation and environmental protection. . With the increase of the power and brightness of the one-pole body or its module, the heat generated by it is also increasing. If the heating problem of the light-emitting diode is not properly solved, the working life of the light-emitting diode lamp Will be seriously affected. Therefore, a heat sink in contact with the LED module is usually disposed in the lamp to dissipate heat from the LED module. However, the light-emitting diode module of the lamp is generally placed horizontally on one side of the heat sink to form a planar light source. Such a planar light source not only generates relatively concentrated heat, but also has a single illumination direction and a limited illumination area, and cannot be Uniform and soft lighting is formed around the luminaire, which makes it difficult to satisfy the user in many cases. SUMMARY OF THE INVENTION 3 201033517 A light-emitting diode lamp includes a plurality of lamp bodies stacked one on top of the other, each lamp body including a heat sink and a light-emitting diode module attached to the bottom surface of the heat sink. The bodies are spaced apart from each other and the size of the lamp body is sequentially reduced. Compared with the prior art, the plurality of lamp bodies of the light-emitting diode lamp of the present invention are stacked one on another 'because the sizes of the lamp bodies are gradually smaller and the lamp bodies are spaced apart from each other'. Moreover, it can avoid the shielding of the lamp body in the lower layer, so that a wide and uniform illumination area is formed around the entire illuminating one-pole illuminator, thereby improving the illumination efficiency of the illuminating diode lamp. Moreover, each of the light-emitting diode modules is respectively connected with a separate heat sink, and each of the heat sinks can directly radiate heat generated by the corresponding light-emitting diode module to improve heat dissipation of the light-emitting diode lamp. effectiveness. [Embodiment] Referring to FIG. 1 and FIG. 2 in March, a light-emitting diode of an embodiment of the present invention is shown.
