structure, especially a heat dissipation module that can be used to illuminate the interior A heat dissipation structure of the LED light group and a street light having the heat dissipation structure of the LED light group are quickly derived from the heat generated by the module. [Prior Art] Each light source has its own characteristics, whether it is incandescent lamp, fluorescent lamp, Jinnan lamp, electrodeless fluorescent lamp, mercury-free fluorescent lamp, and LED for lighting, all have their own unique photoelectric performance. , safety performance, environmental performance and cost performance. Led lamps have a strong potential in lighting applications, and applications and market share will expand rapidly. 'The future may completely replace traditional light sources. With the development of lighting technology, the evaluation of future lighting sources is not only focused on the efficacy of light effects, but also emphasizes lighting effects, light comfort, biological effects of light, fullness of light, and environmental performance. And evaluation of resource consumption. LED lights are compared with traditional incandescent mineral light bulbs and fluorescent lamps. The LED light-emitting diodes have a small invitation, which can be used according to the application object, allowing multiple groups of alpha heat to be low in power, low in power consumption, and long in life. If you look at the environment, you can recycle the waste that does not become environmental pollution, etc. 'Used to connect the traditional (four) appliances as the lighting equipment for the next generation. Among them, low heat generation and low power consumption are characterized by its "low voltage" and "low current" operation. According to the various lamps, the projection lamp has been occupying the proportion of 5 M314825 for a long time, especially when various electronic energy-saving bulbs replace the traditional fluorescent lamps, and the LED lamps can provide them. The lighting effect, but still can occupy the place in the lighting market, regardless of the design of the home decoration Han, as well as the design of various exhibitions, even the street lanterns and public signs, will inevitably use LED lamps According to the implementation, it has the effect of longer life and brightness than the traditional lamp. Moreover, due to the high temperature generated by general LED lamps, the luminous efficiency is greatly discounted, and how to solve the heat dissipation problem becomes an important key. LED lamps, if their heat dissipation design is not good, often cause LED bulbs to burn out due to overheating, and because the high temperature generated by them may cause the lamp or the lampshade to melt, causing high temperature smoldering in the lamps, resulting in unpredictable The disaster has arisen. When a general LED lamp is used in a street lamp structure, it is necessary to take into account not only the heat dissipation problem of the lamp, but also various external factors such as rain, leaves, dust, insects, and black scorpions, etc., which are accumulated and attached. Above the lampshade, the efficiency of the heat dissipation is affected, and the LED lamp is more likely to be short-circuited due to high temperature. Referring to circle one, FIG. 1 is a conventional LED street lamp device. The conventional LED lamp device 1 includes a lamp holder 10, a cover 11, at least one illumination module 12, and a lamp post 13. A plurality of protruding heat sinks 101 are disposed on the top of the lamp holder 10, and the heat generated by the light-emitting module 12 can be indirectly radiated into the air through the lamp holder 10, thereby reducing the illumination generated by the light-emitting module 12. The heat. Since the light-emitting module 12 of the conventional LED street lamp device 1 is embedded in the socket 10 in an embedded manner and is connected to the conductive line, the number of the light-emitting modules 12 cannot be increased or decreased according to lighting requirements. It is not possible to quickly replace the repair during replacement or repair. And the light-emitting module 12 is disposed in the accommodating space of the cover body 11 of the lamp holder 10 6 M314825, and the heat energy generated by the light-emitting module 12 is transmitted to the external heat sink ιοί only through the lamp holder ίο, Therefore, the heat dissipation effect is not good: further, since the external heat sink 101 is exposed to the outside, it is easily contaminated by unidentified objects or rainwater, and the adhesion of the dirt affects the heat dissipation performance at the same time. The lamp holder 10 is connected to the lamp post 13 in a fixed manner. The lamp garden 10 is limited by the height of the lamp post 13 and cannot provide a wider range of projection area according to different needs. Moreover, the projection angle of the lamp holder 10 is more fixed by the lamp holder 131 extended by the lamp post 13, and the appropriate projection angle of the lamp holder 1 cannot be adjusted, so that the illumination angle required for the special road section cannot be adjusted. The LED street light device 1 cannot be used to perform illumination 玺 activity in accordance with different road conditions. [New content] The main purpose of this creation is to provide a heat dissipation structure for LED light groups. In addition, by the arrangement of the heat dissipation module, the side of the lamp can be directly radiated from the inside of the lamp, and it is difficult to adhere to external pollutants, and the increase is greatly increased. The heat dissipation area is used for the purpose of improving heat dissipation efficiency. The second purpose of the present invention is to provide a heat dissipation structure for an LED lamp set, in which the number of the light-emitting modules can be arbitrarily increased or decreased by modularizing the light-emitting module, and the repairer can be easily replaced. Another object of the present invention is to provide a heat dissipation structure for an LED module, wherein an extension arm and a lamp post can be used to completely replace the traditional street lamp, and the illumination effect is better. 7 M314825 In order to achieve the above purpose, the present invention provides a heat dissipation structure with an LED lamp group. The LED lamp group heat dissipation structure mainly comprises a lamp holder, at least one heat dissipation module, and at least one illumination module. . The lamp holder further comprises: a base, a cover body, a support portion, and a rotating shaft portion. The heat dissipation module is formed by arranging and arranging a plurality of metal fins at an appropriate distance, and is fixed between the cover body and the base, and is located at a periphery of the lamp holder, so that a center of the cover raft base is formed. The central interlayer can accommodate the lighting module. The light emitting module further comprises: a main body, at least one LED unit, a circuit board, a calender plate, a heat dissipating unit, and a fixing base. The heat dissipation module can heat the light generated by the light-emitting module in the lamp holder by the metal fin and the metal fin at an appropriate distance between the metal conduction and the air to illuminate the light-emitting module. The heat generated is quickly exported to the atmosphere. The LED lamp group heat dissipation structure can be combined with an extension arm and a lamp post to form a street lamp with an LED lamp group heat dissipation structure. The extension arm further includes: a joint portion, a circuit module, and a connection portion. The hollow joint portion of the extension arm can be combined with the hollow shaft portion of the socket with a bolt to enable the extension arm to pivotally connect the socket, and thereby the socket and the extension arm can be connected by the pivot joint The circuits are interconnected by a circuit, so that the circuit module disposed in the extension arm can provide the power required for the illumination module to be coupled to the lamp holder. The extension arm can be bent at a proper projection angle with the socket and the connection portion of the extension arm can be fixed at an appropriate position of the lamp post to adjust the illumination height and direction area of the lamp holder. In addition, the illuminating module can be modularized and can be coupled to the base of the lamp holder to electrically connect with the conductive line preset on the bottom surface of the base, and increase or decrease according to the road segment with different requirements. The number of lighting modules 'not only the 8 M314825 is easy to install, but also saves energy and reduces unnecessary waste.
