CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority under 35 U.S.C. §119 to Chinese Patent Application Serial Number CN 201520835098.2, filed on Oct. 26, 2015, the disclosure of which is incorporated herein by reference in its entirety. 
       FIELD OF THE INVENTION 
       [0002]    The present disclosure relates to LED (light emitting diode) photoelectric technologies, and more particularly, relates to a LED driving structure. 
       BACKGROUND OF THE INVENTION 
       [0003]    A LED driving structure is generally packaged by a metallic housing, when assembly, in order to meet a requirement of the United States UL safety certification. A metal housing junction box is further provided at an external of the power module to protect a power input/output connection. Thus, much of cost is increased in practical use, and a design difficulty is increased. 
         [0004]    In order to solve the problem of high cost, the conventional LED driving structure adopts a big metal box to seal the power module and the output/input cable therein. However, the temperature of the operational environment of the power module is increased; the operational condition of the power module is harsh, thereby reducing a service life of the LED driving structure. 
       SUMMARY OF THE INVENTION 
       [0005]    Therefore, it is necessary to provide a LED driving structure having a better working environment for the power supply. 
         [0006]    A LED driving structure includes: a lower housing, being a box structure and having an opening end; a upper housing positioned on the opening end of the lower housing, and covering a part of the opening end; a separating board positioned an end of the upper housing and being perpendicular to the upper housing, the upper housing, the separating board, and a part of the lower housing cooperatively form an electrical chamber; and an upper cover positioned on the opening end of the lower housing, wherein the upper cover and the upper housing cooperatively cover the opening end, the upper cover, the separating board, and the rest part of the lower housing cooperatively form a wiring chamber. 
         [0007]    In above LED driving structure, the lower housing, the upper housing, the separating board, and the upper cover and other components cooperatively form the independent electrical chamber and the independent wiring chamber, to separate the electrical module such as the power source module from input/output wiring wires, thereby ensuring the power source module to be able of working in an independent environment, reducing a temperature of the working environment, improving the working environment, extending a service life of the power source module, and meeting a requirement of the United States UL safety certification
