No. 15/207,479 filed on Jul. 11, 2016 which is a Continuation application of PCT application No. PCT/CN2015/079833 filed on May 26, 2015, which claims the benefit of Chinese Patent Application No. 201420275988.8 filed on May 27, 2014; the contents of which are hereby incorporated by reference. 
     
    
     TECHNICAL FIELD 
       [0002]    The present application relates to the technical field of lighting devices, and in particular to a multifunctional module-type light which can be combined arbitrarily. 
       BACKGROUND 
       [0003]    With the continuous development of LED technology, LED lamps gradually replace the traditional incandescent lamps and halogen lamps. LED lamps have many advantages, and so manufacturers are committed to the development of such LED lamps. Especially for outdoor lighting where large illuminated area and wide light source are required, using the traditional lighting will consume a lot of energy. Thus, making use of LED lighting is the current trend of development. 
         [0004]    Although an LED lamp has certain advantages, there are some problems need to be solved: 
         [0005]    1. Product design is problematic. At present LED lighting products usually adopt one-to-one design. That is, one lamp housing can only produce lighting products of a specific power range. If one needs to develop a series of lighting products, one needs to design a series of different lamp housings. Development cost becomes very high. 
         [0006]    2. Heating is a problem because LED lights use LED light panels of high power as the light source. The large amount of heat, if not timely dissipated, can easily lead to overheating of the LED light, thereby affecting the normal operation of the light. It will also lead to expansion and contraction, causing product sealing and water leakage problems. 
         [0007]    3. Light projection area and projection angle are to be concerned. The structure of a traditional LED light is an overall design, and cannot be combined arbitrarily. 
         [0008]    Under different environments, different LED lightings require different light projection areas, and LED lightings having only one standard apparently cannot meet the needs of the modern society. For example, LED street lights for a main road require greater outdoor brightness and wider illumination. On the other hand, small pedestrian streets require smaller outdoor brightness and narrower illumination. However, street lights of different design specifications need new design and development of different molds and different circuit structures. These increase manufacturing costs because lights with different specifications require different mold productions and assembly parts. 
         [0009]    Aiming at the above problems, the present application provides an improved multifunctional module-type light. 
       SUMMARY 
       [0010]    The technical problem to be solved in the present application is to overcome the shortcomings, and provide a multifunctional module-type light. 
         [0011]    In order to solve the technical problems, this application uses the following technical scheme. According to one aspect, there is provided a multifunctional module-type light including a light-emitting module and a supporting assembly, wherein the light-emitting module includes at least one LED module, a plurality of the LED modules being connected via a connecting assembly, the supporting assembly including a supporting frame and a positioning assembly, wherein the supporting frame is installed on the light-emitting module in a manner that an angle thereof is adjustable through the positioning assembly, the supporting frame includes two installation feet connecting with the light-emitting module and a supporting plate connecting between the two installation feet, the supporting plate in a first embodiment and a second embodiment comprises a flat surface, and the supporting plate in a third embodiment and a fourth embodiment comprises a slanted surface, and the light-emitting module is fixed on a surface through the supporting plate. 
         [0012]    In one embodiment, each LED module includes a heatsink, a light-transmitting cover fixed on the heatsink, a driving device and an LED light panel, the heatsink including a mounting surface and a plurality of heat-dissipating fins formed on the mounting surface, and the light-transmitting cover being formed thereon with a plurality of reflectors to meet light distribution requirements in different angles. 
         [0013]    In one embodiment, the light-emitting module includes one independent LED module, wherein the support frame is disposed across the heatsink of the LED module, and the two installation feet of the supporting frame are installed on the heat-dissipating fins at two sides of the heatsink in a manner that an angle thereof is adjustable through the positioning assembly. 
         [0014]    In one embodiment, the light-emitting module is formed of a plurality of LED modules parallel connected in a horizontal plane, wherein rows of the LED modules are connected by the connecting assembly, and columns of the LED modules are connected by the driving devices provided on the heatsinks. 
         [0015]    In one embodiment, the connecting assembly is in the form of a plurality of connecting rods, wherein each connecting rod is fixed on an outermost heat-dissipating fin of the heatsink on one side of each LED module through a bolt, two ends of the drive device are respectively connected to the heat-dissipating fins of the LED module by connecting pieces, and the LED modules are connected at a certain angle with respect to each other through the connecting rods. 
         [0016]    In one embodiment, the positioning assembly includes a positioning disk formed with a plurality of positioning grooves, and fixed on an upper surface of the light-emitting module. 
         [0017]    In one embodiment, the supporting frame is installed on the heat-dissipating fins of the LED module, and the positioning disk is fixed on the heat-dissipating fins, and the supporting feet of the supporting frame are fixed on the heat-dissipating fins through a plurality of bolts. 
         [0018]    In one embodiment, the supporting frame is installed on corresponding connecting rods and the positioning disk is fixed on the connecting rods, and the supporting feet of the supporting frame are fixed on the connecting rods through a plurality of bolts. 
         [0019]    In one embodiment, the supporting plate of the supporting frame is formed with at least one installation hole, and is fixed on a horizontal surface by at least one screw. 
         [0020]    Adopting the above-mentioned technical scheme and comparing with the existing technology, the multifunctional module-type light of the present application has the following advantages: 
         [0021]    1. Using modular units, breakthrough of power restriction in a conventional lamp with a single housing can be achieved. In conventional lighting products, design of a lamp housing can only produce lighting products having only a specific power range. Therefore, in order to develop a series of lighting products, one needs to produce a variety of housing designs, and the development cost is very high. The present application uses modular design structure, so that a light-emitting module can be formed by combining a plurality of independent LED modules through connecting pieces. One can select the appropriate number of LED modules according to the need of the environment so that it can form lighting of different specifications to suite different environments. The design of the modularization structure not only saves the production cost, each module can be conveniently disassembled and maintenance cost can be also saved. 
         [0022]    2. Light distribution curve and projection angle can be adjusted. For conventional lighting products, a lighting product of one model usually has only one light distribution curve and projection angle. Some lighting devices can adjust the projection angle through a supporting frame. However, a lighting product of one model only has one light distribution curve. Different illuminating environments need different light distributions. This leads to a great problem in lighting design. In this application, the multifunctional module-type light is innovative in that each module has angle and positioning adjustment within a certain range. The supporting frame and connecting assembly are provided with angle-adjusting function. The supporting frame can be installed on a light-emitting module through a supporting assembly in order to adjust the angle. LED modules are connected by connecting rods. One can adjust the angle of projection of each module in the whole lighting device, so as to achieve a lighting device having many light distribution curves. With the projection angle adjustment on the supporting frame, a lighting product of the same model can meet different environment lighting needs. This can greatly simplify the lighting design. 
         [0023]    3. Size and weight of high-power lighting devices can be reduced. For conventional high-power lighting products, in order to meet the three aspects of need, namely, light distribution, heat dissipation, and built-in driver, the size and weight of the lighting housing are increased. However, increase in size and weight will cause great inconvenience in installation. The need for more investment in human resources, tests on installation position and space, and load-bearing capacity would waste installation cost. Especially in outdoor installation under the effect of wind, weight and other external force, safety requirement of lighting devices is higher, size and weight of lighting device are greater, and there will be more hidden safety issues. The innovation of the multifunctional module-type light of the present application lies in the unique combination of light-emitting modules and power supply modules. This greatly reduces the size and weight of the lighting device, and makes installation more convenient as the size and weight reduce, the effect of external force reduces accordingly, and potential safety hazard reduces accordingly. 
         [0024]    4. Modular design reduces maintenance cost. For conventional lighting products, the whole lighting device is sealed. When a part of the whole lighting device is broken, the whole lighting device needs to be disassembled for maintenance. Thus, maintenance cost is very high. The innovation of the multifunctional module-type light of the present application lies in the modularization of light-emitting modules and power supply modules. When a part is broken, one only needs to disassemble the connecting assembly and only replaces the broken module. There is no need to disassemble the whole lighting device for maintenance. This can greatly reduce the maintenance cost. 
         [0025]    5. The multifunctional module-type light of the present application can be used to meet the needs of different outdoor locations such as advertising lighting, regional lighting, sports lighting, building accent lighting, road lighting and other outdoor locations.
