         [0155]    With reference to  FIGS. 3 and 3 ( c ), the support frame  3  is an opening concave hemispherical structure installed in the conductive plate  2  having a 3D curved surface and formed by a plurality of radially arranged support ribs  30 , and each support rib  30  has fixing columns  33   a ,  33   b  which are group into two, and more than one ventilation hole  34  are formed between each support rib  30 ; the center of the support frame  3  has a fixing ring  31  and the external circumference of the support frame  3  has an external circular surface  32 ; each group of fixing columns  33   a ,  33   b  are passed through and combined with each group of fixing holes  27   a ,  27   b  of the conductive plate  2 , and the fixing ring  31  is passed through the center hole of the positioning portion  25  of the conductive plate  2 ; the external circular surface  32  of the support frame  3  is disposed on an opening end and capable of attaching the bending portion  24   b  of the conductive plate  2 , and the latch slot  35  is provided for fixing the lamp cover  6  and the protective cover  7 . The power module  51  is installed in the protective cover  7  and a power cord is connected to the conductive plate  2  and the connector  5 . It is noteworthy that each fixing hole  27   a ,  27   b  of the conductive plate  2 , the fixed planar structure  28  of the circular strip, and the support rib  30 , the support surface  301  and each fixing column  33   a ,  33   b  of the support frame  3  form the electrode soldering point protection mechanism of the LED chip of the illumination apparatus c of this embodiment, and the manufacturing method  9  of an illumination apparatus of the following embodiment also has the LED chip electrode soldering point protection mechanism. 
         [0156]    With reference to  FIG. 2( i )  for a manufacturing method of an illumination apparatus c of this embodiment, the manufacturing method comprises an unloading process, a mounting process, a reclaiming process, a formation preparation process, a pre-assembling bending process, an assembling process, an auxiliary portion removing process and a post-assembling bending process.

With reference to  FIG. 3( d ) , the strip structure  20  near the bending portion  24   b  is reduced along the circumferential direction to further reduce the width of each isolation slot  21 , and each V-shaped connecting portion  23  is bent further into a deep V-shape. In other words, the stamping board  80  (which is the conductive plate  2 ) with a planar structure is a conical structure. Now, each LED chip  11  is installed on an inner side, wherein each strip structure  20  along the circumferential direction is not bent into a curved surface yet. In this process, the fixed planar structure  28  of the circular strip still maintains to be planar to protect the electrode soldering point of the LED chip  11 , so as to minimize the deformation, since most deformations usually occur at the connecting portion  23  and the isolation slot  21  with a reduced width. 
         [0158]    With reference to  FIGS. 3( c ), 3( d ) and 3( e )  for the pre-assembling bending process, the pre-assembling bending process further comprises a concave spherical surface bending process and a concave circular curved surface bending process, wherein the concave spherical surface bending process uses a stamping mold to press and fix the positioning portion  25  and the circular strip fixed planar structure  28  at a predetermined conical angle, and then the bending portion  24   c  is bent into the concave spherical surface  241   a , and the concave circular curved surface  242   a , the conical curved surface  243 , and the cylindrical surface  244  form a conical surface. Now, the width of the isolation slot  21  disposed at the external diameter is reduced significantly. 
         [0159]    With reference to  FIG. 3( e ) , the concave circular curved surface bending process uses the stamping mold to press and fix the positioning portion  25  and the circular strip fixed planar structure  28  and bend the bending portion  24   b , so that the conical curved surface  243  and the cylindrical surface  244  form a radial plane, and each LED chip  11  is still disposed on the inner side, and the width of the isolation slot  21  disposed on the concave circular curved surface  242   a  is reduced, and the width of each isolation slot  21  disposed on the external diameter is relatively larger due to the planar shape. And then, the positioning portion  25  is cut and removed to form the circular center hole, and the stamping mold is used again to press and fix the circular strip fixed planar structure  28  and bend the bending portion  24   b , so that the concave circular curved surface  242   a  is formed. In other words, the concave spherical surface  241   a  and the concave circular curved surface  242   a  jointly form a concave hemispherical curved surface. 
         [0160]    With reference to  FIG. 3( e ) , the bending portion  24   b  is bent, and a inverted U-shape is formed between the concave circular curved surface  242   a  and the conical curved surface  243 , and the conical curved surface  243  and the cylindrical surface  244  form an outwardly flapped cylindrical shape, and the V-shaped connecting portion  23  disposed across the isolation slot  21  is further bent, and the width of the isolation slot  21  on the conical curved surface  243  and the cylindrical surface  244  is reduced.

         [0162]    With reference to  FIG. 3( e )  for the auxiliary portion removing process, the stamping mold is used for pressing the support frame  3  and the conductive plate  2  and cutting open each auxiliary portion  221 , and the position of the original short-circuit auxiliary portion  221  becomes the electrode slot  22 .

With reference to  FIG. 3( f ) , the stamping mold is provided for fixing the support frame  3  and forming a conical curved surface  243  and a cylindrical surface  244  of the conductive plate  2 . Since the bending portion  24   b  and the bending portion  24   a  have a bending hole (not shown in the figure), the structural strength is weakened, and the stamping mold can bend the bending portions easily, and the external circular surface  32  of the support frame  3  is attached to the U-shaped bending portion  24   b  to provide the required support for the following bending operation, and form the conical curved surface  243  and the cylindrical surface  244 , so as to complete the three-series-three-parallel illumination circuit  1  of this embodiment.
