Title: Solar cell module

Description:
FIELD OF THE INVENTION 
     The present invention relates to a solar cell module and, more particularly, to a solar cell module for proper operation under various conditions. 
     DESCRIPTION OF THE RELATED ARTS 
     Referring to  FIG. 8 , a conventional solar cell module includes a circuit board  6 , a plurality of solar cells  7  fixed on the circuit board  6  by soldering, and a lens  8  for focusing sunlit onto the solar cells  7 . The solar cells  7  convert the focused sunlit into electricity. However, each of the solar cells  7  converts sunlit into electricity at different efficiencies in different seasons. Moreover, solar cells  7  in different positions of the circuit board  6  convert sunlit into electricity at different efficiencies. The single lens  8  cannot effectively focus sunlit onto the solar cells  7  so that the solar cells  7  cannot efficiently convert the focused sunlit into electricity. 
     The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art. 
     SUMMARY OF THE INVENTION 
     It is the primary objective of the present invention to provide a solar cell module for proper operation under various conditions. 
     To achieve the foregoing objective, the solar cell module includes a solar cell, a ring and a lens. The solar cell includes at least one photo detector provided on the top, a plurality of pins extended from the bottom and at least a mark formed thereon for marking the pins. The ring, with an upper window and a lower window, is detachably mounted on the solar cell. The lens is disposed in the ring for closing at least one of the upper and lower windows. 
     Other objectives, advantages and features of the present invention will become apparent from the following description referring to the attached drawings.

     DETAILED DESCRIPTION OF EMBODIMENT 
     Referring to  FIG. 1 , there is shown a solar cell module according to the preferred embodiment of the present invention. The solar cell module includes a solar cell  1 , a ring  2  and a lens  3 . The solar cell  1  can be combined with the ring  2  so that the lens  3  is provided over the solar cell  1 . Referring to  FIGS. 2 ,  6  and  7 , the solar cell  1  can be disengaged from the ring  2  so that the lens  3  can be replaced with another lens when the working conditions change for the solar cell module. 
     Referring to  FIGS. 2 through 4 , the solar cell  1  preferably includes three photo detectors  11  three pins  12  each extended from a related one of the photo detectors  11 , a mark  13  formed thereon and a thread  111  formed thereon. The mark  13  may preferably be a tab formed on the periphery of the solar cell  1  or a unique area on the solar cell  11 . The thread  111  is preferably formed along the periphery of solar cell  1 . 
     The ring  2  is detachably mounted on the solar cell  1 . The ring  2  includes an upper internal annular flange and a lower internal annular flange. An upper window  22  is defined by the upper internal annular flange. A lower window  23  is defined by the lower internal annular flange. A thread  21  is formed along the lower internal annular flange. 
     The lens  3  is disposed in the ring  2  to close at least the upper window  22 . 
     Referring to  FIG. 5 , the solar cell  1  is provided on a circuit board  4 . The pins  12  are inserted in apertures  41  defined in the circuit board  4 . The apertures  41  are of different electrodes. The mark  13  lets an assembling persona know the electrodes of the pins  12 , thus avoiding the insertion of the pins  12  into wrong apertures  41 . 
     The sun  5  casts sunlit onto the solar cell module. The lens  3  focuses the sunlit onto the photo detectors  11 . The photo detectors  11  convert the focused sunlit into electricity. 
     Referring to  FIGS. 2 ,  6  and  7 , for some reasons, the lens  3  can be replaced with another lens after the solar cell  1  is disengaged from the ring  2 . 
     Referring to  FIG. 6 , ring  2  is disengaged from the solar cell  1  so that the lens  3  can be replaced with another one. 
     Referring to  FIG. 7 , the lens  3  is secured to the ring  2 . The ring  2  and the lens  3  are disengaged from the solar cell  1  and replaced with another ring and another lens. 
     The present invention has been described via the detailed illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
