     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention will be apparent to those skilled in the art by reading the following detailed description of preferred embodiments thereof, with reference to the attached drawings. 
       FIG. 1  is a perspective view showing an integrated multi-layered illuminating assembling unit of the present invention, and  FIG. 2  is a section view showing an integrated multi-layered illuminating assembling unit of the present invention. The present invention relates to an integrated multi-layered illuminating unit which can adapt to different purposes and locations of use by assembling with multiple units thereof to improve the illuminating range and intensity. 
     An integrated multi-layered illuminating unit of the present invention mainly comprises a heat dissipating base  1  and two lead wires  3 . 
     The heat dissipating base  1  includes a first front side  11  and a second front side  13 , wherein the second front side  13  is located on the opposite side of the first front side  11  of the heat dissipating base  1 , and at least one slot compartment  111  is disposed on the first front side  11 . As shown in the preferred embodiment of  FIG. 1 , four slot compartments  111  which are arranged in pairs can be disposed. The second front side  13  forms a plurality of cooling fins  131  where the cooling fins have a gap between each fin. 
     It should be noted that the number and the configuration of slot compartments  111  should be decided according to the actual needs and situation, so is the shape of the heat dissipating base  1 . The preferred embodiment described here is for illustrating purpose only, and the scope and variations of the present invention is not limited thereto. The heat dissipating base  1  can also be the rectangle shape shown in  FIG. 3 , so the slot compartments  111  are arranged in a straight line with intervals. 
     As shown in  FIG. 1  and  FIG. 2 , a base surface  1111  and an inner circular wall are disposed in the slot compartment  111  of the heat dissipating base  1 , wherein an emitting element  5  is disposed on the base surface  1111  and the emitting element  5  is wire bonded to each other. Two openings  15  are disposed between the second front side  13  and the base surface  1111  of the slot compartments  111 . The light emitting elements  5  are arranged in arrays, and can be LEDs or other elements with illuminating functions. 
     The inner circular wall  1113  is an inclined plane so the light emitted by the emitting element  5  can be reflected by the inner circular wall  1113  to the outside of the slot compartments  111 . A reflective mask (not shown in graph) can be installed on the inner circular wall to improve the reflective rate of the emitting element  5 , so the irradiation intensity and uniformity of the emitting element  5  are enhanced. 
     As shown in  FIG. 2 , two lead wires  3  are wired bonded to the emitting elements  5  to form electrical connections, and two lead frames are installed through the two openings  15 , wherein the closer end of the two openings  15  to the slot compartment  111  is sealed with a sealing material  6 , and the further end of the two openings  15  from the slot compartment  111  is sealed and fixated with a plug  4 . Other than isolating moisture and dust, the sealing material  6  and the plug  4  also serve to fixate two lead frames  3 . The sealing material  6  can be silicone resins or epoxy resins with high attachment and high temperature tolerance. The better silicone resins choice should have zero light transmittancy, so when the light emitted by the emitting element  5  incident the silicone resins, the silicone with zero light transmittancy can reflect the emitted light from the emitting element  5  to the outside of the slot compartments  111 , therefore improves the light transmission efficiency. 
     The space within the two openings  15  can be filled with a polymer compound  7  with high heat conduction performance, so two lead frames  3  are embedded and the heat generated can be dissipated to heat dissipating base  1  quickly. 
     A wireless transmission unit  10  and a power supply unit  20  can be installed on the heat dissipating base  1 , wherein the wireless transmission  10  can be a standard IEEE802.11 wireless transmission module or a Bluetooth transmission module, and is at least one of them. 
       FIG. 4  shows a schematic view of the first preferred embodiment of an integrated multi-layered illuminating assembling unit of the present invention. Followed by the previous description, the present invention can further comprise an optical mask  8  and a diffusing mask  9 . The optical mask  8  is located on the light emitting element  5  and is connected with the slot compartment  111 , so the slot compartment  111  becomes an enclosed space to prevent moisture and dusts from entering. The diffusing mask  9  is located on the heat dissipating base  1  and is connected with the heat dissipating base. The optical mask  8  and the diffusing mask  9  are used to diffuse the light emitted by the emitting element  5 , so the irradiation uniformity can be enhanced. 
       FIG. 5  shows a utilization drawing of an integrated multi-layered illuminating assembling unit of the present invention. The heat dissipating base  1  can be installed on a wall  200  with a heat insulating block  300  in between. Through the installation of heat insulating block  300 , a space for ventilation is generated between the heat dissipating base  1  and the wall  200 . Therefore, the heat generated from the heat dissipating base  1  can be conducted to the ventilating space described above, and the heat can be dissipated quickly by the ventilation of the air. 
     The present invention can be assembled with a plurality of the heat dissipating bases  1 , wherein any two adjacent heat dissipating bases  1  can be assembled into different forms of illuminating units by installing the connecting members  100 , as shown in  FIG. 6 . The structure of the heat dissipating base  1  thereof and the assembling relations with the emitting element  5  and the lead wires  3  are described in the paragraphs above therefore will not be mentioned here again. 
       FIG. 6  shows a schematic view of the second preferred embodiment of a multi-layered illuminating assembling unit of the present invention. Two heat dissipating bases  1  thereof can be assembled and the two heat dissipating bases  1  are configured correspondingly, so the two corresponding sides of the two heat dissipating bases  1  are connected through two connecting members  100 . The connecting member  100  includes a connecting grip  100   a  and two screws  100   b . In order to assembled the two heat dissipating bases  1 , the connecting grip  100   a  is placed in a way that the two ends of the connecting grip  100   a  are on the same side of the two heat dissipating base  1  separately, and then the two screws  100   b  are fastened on the two ends of the connecting grip  100   a  to be screwed into the heat dissipating base  1 . 
     In the preferred embodiment, the two connecting members are fixated on the top and bottom of the heat dissipating base  1  separately, with the second front side  13  of the two heat dissipating base  1  facing each other. In other words, the cooling fins  131  of the two heat dissipating bases  1  are facing each other, therefore the slot compartments  111  which are installed with the emitting element  5  should be set up facing outward. Through such configuration of the heat dissipating bases  1 , the assembled illuminating unit can have two light beams projecting in different directions, so the irradiation range can be enlarged. 
     Furthermore, the thickness between the cooling fins  131  of the second front side  13  and the emitting element  5  of the first front side  11  is very thin, thus the heat generated from the light emitting element  5  can be conducted to the cooling fins  131  on the other side immediately. In addition, the ventilating air between the cooling fans  131  can conduct the heat away to keep the heat from building up; therefore, the emitting element  5  can work under proper temperature continuously to keep up the best luminous efficiency. 
     As shown in  FIG. 7 ,  FIG. 8  and  FIG. 9 , the heat dissipating bases  1  can be arranged into a triangular, quadrilateral, polygon and other possible shapes of illuminating unit depending on the actual number of assembling units used. The sides of the heat dissipating bases  1  can be set as chamfered surface, so the adjacent heat dissipating base  1  can be more united and closer to each other when assembled. 
     All the slot compartments  111  with the emitting elements  5  should be set up facing outward. As shown in  FIG. 7 , the preferred embodiment uses three heat dissipating bases  1 . The illuminating unit can be a triangular shape illuminating unit with three directions of light beams through proper configuration and assembling. When the emitting elements  5  in all three heat dissipating bases are lit simultaneously, the triangular illuminating unit will give a lighting effect of 360 degrees visually. Therefore, the irradiation range and intensity of the illuminating unit can be increase multiply. 
       FIG. 10  shows a schematic view of the third preferred embodiment of an integrated multi-layered illuminating assembling unit of the present invention. The heat dissipating base  1  can be installed onto the lamp body  400 , wherein the lamp body  400  can cover the diffusing mask  9 , and a lamp fitting  410  is disposed on the bottom of the lamp body  400 . The lamp body  400  has a containing space (not shown on graph) within, where the wireless transmission unit  10  and the power supply unit  20  can be installed in. This preferred embodiment uses the lamp body  400  of a sphere bulb as example; however, the scope of the invention should not be limited hereto. All the lamp bodies of an illuminating device are included in the scope of the invention. 
     As shown in  FIG. 10 , four heat dissipating bases  1  are used and the first front side  11  of the four heat dissipating bases  1  are facing outward of the lamp body  400 . Preferably, the four heat dissipating bases  1  are arranged in pairs to form a quadrilateral shape. When the emitting elements  5  of the four heat dissipating bases are lit simultaneously, the quadrilateral illuminating unit will give a lighting effect in all directions visually. Therefore, the irradiation range and intensity can be increased multiply. 
     The advantage of the disclosure is that the number of the heat dissipating base  1  used to assemble the illuminating unit can be determined based on the purpose and the location of use, and so is the assembling method. In addition, the assembling of the heat dissipating bases only relies on the connecting members  100 , and the actual operation of the connecting members is very convenient, fast and simple, thus the production and maintenance process are very time and cost saving. In short, the illuminating unit provided by the present invention can be assembled into suitable forms based on different applications and purposes of use to provide proper irradiation range and intensity. 
     The preferred embodiment described above is disclosed for illustrative purpose but to limit the modifications and variations of the present invention. Thus, any modifications and variations made without departing from the spirit and scope of the invention should still be covered by the scope of this invention as disclosed in the accompanying claims.
