BACKGROUND OF THE INVENTION 
       [0001]    This invention is regarding to a technique that can optimize the absorption of solar power within a limited space, and prolong the life of solar panels. 
         [0002]    Current solar power collecting techniques generally come from two methods by principles: (1) utilize and achieve through heat chamber. (2) utilize reflection mirrors or lens to focus sunlight on the surfaces of solar panels for them to absorb. Aforementioned two methods can both achieve to turn solar power into electricity, but they require big space and dimension to collect sufficient solar power. Unfortunately, the bigger size the apparatus is, the costly it will be. In Taiwan Patent Publication Number: M3 18670 “Refraction-based solar power collector”, for example, it comprises: a light-directing device, a transparent body with continuous pyramid-structured, a reflective device used to reflect the light refracted from the light-directing device and a solar panel. The light-directing device, reflective device and the solar panel form into a cube with the solar panel at bottom, the light-directing device between the light source and the solar panel, and the reflective device between the light-directing device and the solar panel. The light-directing device first refracts the light onto the reflective device, and then light will be reflected onto the solar panel for collecting solar power. 
         [0003]    Although the light-directing and reflective devices can greatly have sunlight focused on the solar panel, it indeed also has following drawbacks: (1) Although the its solar panels are properly spaced to save manufacturing costs, it encounters the loss of some sunlight and may at some certain times fail to direct lights focused onto the solar panel due to the displacement of sunlight, thus causing low collecting efficiency. (2) Like other regular solar-power collectors, such equipment also requires the wide placement of solar panels when in condition of unable to fully absorb sunlight, causing high implementing costs and thus hard to get popular. (3) In real practice, the focused sunlight from the light-directing devices ever burned the solar panel. Thus, with long time investments in researches and experiments, the inventor finally found an improved structure that can prevent aforementioned problems, and thus hereby proudly files application of patent to protect intellectual property. 
       BRIEF SUMMARY OF THE INVENTION 
       [0004]    This invention proposes a solar-power collector that can double collect solar power under same total solar panel size as traditional apparatus. Accordingly, it can generate sufficient electrical power without requiring solar panel of big dimension, can be produced at lower unit cost, can be spread out more easily to regular households, and it has also the feature of long life. 
         [0005]    To reach the abovementioned ends, the invention proposes a solar-power collector, which comprises: 
         [0006]    A transparent light deflector—composed of stacks of transparent plates, it has multiple convexes and concaves on either its top of bottom surface. The convexes can be either round-shaped, cone-shaped, pyramid-, awl-shaped, or trapezoid column-shaped, and their arrangement can be in either crisscross or random alignments; 
         [0007]    Two or more layers of solar panel modules—they are placed beneath the light deflector. Each solar panel module is composed of multiple solar panels that scatter around, and the solar panels of upper and lower layers are intercross placed. With so, sunlight can focus and disperse through the convexes and concaves of the light deflector, and the upper layer of solar panel module absorbs the dispersed sunlight while the lower layer module, through the gaps between panels of upper layer module, absorbs the after-focus dispersed sunlight. This is designed so to fully absorb sunlight and avoid overheating problem when sunlight just focuses on certain points on solar panels.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0016]    Further, please be described of a preferred embodiment as below. First referring to  FIG. 1 and 2 , the invention comprises: a transparent light deflector  10 , and at least upper and lower layers of solar panel modules  21 ,  22  below the light deflector  10 . 
         [0017]    The transparent light deflector  10  has multiple convexes  11  and concaves  12  on either its top of bottom surface. The convexes  11  can be either round-shaped, cone-shaped, pyramid-, awl-shaped, or trapezoid column-shaped. The concaves  12  can be not only on top surface but also on bottom surface at the corresponding positions to the convexes  11  as shown in  FIG. 3 . The arrangement of the convexes  11  can be in either 2-D crisscross or random alignments, thus looks continuous or intercross wave-shape, triangle-shape or trapezoid-shape in its sectional view. 
         [0018]    The two layers of solar panel modules  21 ,  22  placed beneath the light deflector. Each solar panel module is composed of multiple solar panels in 2-D alignments, and the solar panels of the two modules are placed in an intercross format. With so, sunlight can focus and disperse through the convexes  11  and concaves  12  of the light deflector  10 , and the upper solar panel module  21  absorbs the dispersed sunlight while the lower module  22 , through the gaps between solar panels of upper module  21 , absorbs the after-focus dispersed sunlight. This is designed so to effectively and fully absorb sunlight power and avoid overheating problem when sunlight just focuses on certain points on solar panels. 
         [0019]    For supplements, the gap between the solar panels of upper solar panel module  21  cannot be too small, because too small gap may cause over-concentration of solar power, which may burn down the solar panels. Thus, the design of convexes  11  should be so that the solar panels can bear the temperature of the solar power coming through the convexes  11 . 
         [0020]    Further, the invention also comprises a containing body  30  used to contain and position light deflector  10 , upper solar panel module  21  and lower solar panel module  22 . The containing body  30  can be so that inside its four side and bottom plates set heat-insulation layers  31 , and inner walls of them get coated with reflection layers. 
         [0021]    Furthermore, this invention can be also implemented as below examples. As shown in  FIG. 3 , the light deflector  10  is composed of multiple lens units  100 , each of which contains of a convex part  11  and its corresponding concave part  12 . The convex parts  11  are trapezoid column-shaped and in 2-D crisscross alignment, and they are capable of making sun light disperse-after-focus. The light deflector looks continuous trapezoid-shaped in its sectional view. 
         [0022]    As shown in  FIG. 4 , the light deflector  10  is composed of multiple trapezoid column-shaped lens  13 , and looks continuous trapezoid-shaped in its sectional view. And as shown in  FIG. 5 and 6 , the light deflector  10  is composed of multiple round-shaped lens units  14  so that it perform as convex and concave lens, and it looks wave-shaped in its sectional view. Further as shown in  FIGS. 7 and 8 , the light deflector  10  is composed of multiple pyramid-shaped lens units  15  that are in either 2-D crisscross or interlace alignment, and it looks continuous or intercross triangle-shaped in its sectional view. 
         [0023]    With all aforementioned, the invention deserves grant of a patent based on its capability of industrial application and absolute novelty. The example illustrated above is just an exemplary embodiment for the invention, and shall not be utilized to confine the scope of the patent. Any equivalent modifications within the scope of claims of the patent shall be covered in the protection for this patent.
