The loose end  82  further comprising a holding porting for the grasp of the hands in order to pulling the strap. 
         [0019]    This invention further enhances the functionalities of illumination or decoration, thereby not only controls the on-off and illumination modes of the illuminating element, but also adds colorful painting materials on the inner surface  32  of the lamp shade  30 , or the lamp shade  30  is made of plastic material with different colors, or selecting LED&#39;s with different emitting color as illuminating element  20 . The aforementioned colors can be selected in the different combinations without specific limitation and enable the lamp structure  1  generating light with different colors, thereby enhance the effect of illumination and decoration. 
         [0020]    Moreover, there installed a supporting plate  15  in the internal cavity  11  of the lamp body  10 , such that the switch  40  can be secured on one of the side surface  151 . 
         [0021]    As shown in  FIG. 2 , there installed a first securing hole  611  on the first termination  61  of the pressing plate  60  for securing one end of the spring object  70 , and a second securing hole  612  on the second termination  62  of the pressing plate  60  for securing the fixed end  81  of the strap  80 . 
         [0022]    At a proper location in the internal cavity  11  of the lamp body  10  is further installed a securing portion  16  for one end of the spring object  70  can be flexibly secured at this securing portion  16 , while the other end flexibly connected with the first termination  61  of the pressing plate  60 . In this embodiment, the securing portion  16  is formed integrally on the protuberance of the side surface  151  of the supporting plate  15  in the cavity  11  (as shown in  FIG. 2 ), but not limited to the said formation, for example, is formed integrally on the surface of the internal cavity  11  (not shown in the figures), wherein the securing portion locates below the first termination  61  of the said pressing plate  60 . 
         [0023]    At a proper location in the internal cavity  11  of the lamp body  10  is further installed a stopping portion  17  for providing functionalities of stopping and securing to the pressing plate  60  when bouncing back by the recoil of the spring object and rotating counterclockwise around the pivotal axis, wherein the said stopping portion  17  can be formed integrally on the protuberance of the side surface  151  of the supporting plate  15  in the cavity  11  (as shown in  FIG. 2 ), but not limited to the said formation, for example, is formed integrally on the surface of the internal cavity  11  (not shown in the figures), wherein the stopping portion locates above the first termination  62  of the said pressing plate  60 . 
         [0024]      FIG. 5  shows the contacting operation of the pressing plate  60  and the switch  40  in this invention. In the state as shown in  FIG. 4 , the strap  80  is pulled at the loose end  82  in the direction of moving away from the bottom of the lamp body  10 , thereof the pressing plate  60  is also moved and rotated around the pivotal axis  63  clockwise thereafter contacting the switch  40 , and subsequently the switch is pressed and thereby controls the on-off and illuminating modes (i.e., turn-on, turn-off, and twinkling).
