     Reference is made to  FIG. 3 , which shows the assembly cross-sectional diagram of a locking mechanism of the replaceable illumination module of the present invention. In this embodiment, the way that the connection screw  26  fastens the rotation locking flake  25  with the rotation sleeve  22  is described as below. The rotation locking flake  25  has a screw-locking portion  252  that extends from the bottom of the rotation locking flake  25  into the rotation sleeve  22 . The rotation sleeve  22  has a convex ring  224  that protrudes inwards from the inner wall surface to stop the screw-locking portion  252 . The connection screw  26  has a head portion  261  for contacting the convex ring  224 , and a rod portion  262  that passes through the convex ring  224  and is locked with the screw-locking portion  252 . Thereby, the rotation locking flake  25  is fastened with the rotation sleeve  22 . 
     Reference is made to  FIGS. 1 and 3 . The assembly way and disassembly way of the replaceable illumination module for an embedded lamp is described as below. First, the rotation locking flake  25  passes through the opening  140  of the top frame  14 . Next, the replaceable illumination module for an embedded lamp is pushed upwards. In this embodiment, the user pushes the external mask  282  of the lamp set  28  from the bottom of the embedded lamp  1 . At his times, the stop ring  24  is stopped by the top frame  14 , and the connection base  21  moves upwards until the connection base  21  contacts the bottom surface of the top frame  14 . The spring  27  is compressed. 
     Reference is made to  FIG. 4 , which shows assembly cross-sectional diagram of a locking mechanism of the replaceable illumination module being locking of according to an embodiment of the present invention. When the connection base  21  moves upwards, the guiding blocks of the middle sleeve  23  and the sliding blocks of the rotation sleeve  22  moves downwards along the concave slots. As shown in the figure, the guiding blocks  232   a ,  232   c  and the sliding blocks  222   a ,  222   c , move downwards. In this embodiment, the depth of the concave slot is smaller than the sum of the height of the guiding block and the height of the sliding block. Therefore, the guiding blocks  232   a ,  232   c  are still in the concave slots  213   a ,  213   c . The sliding blocks  222   a ,  222   c  are moved to outside of the concave slots  213   a ,  213   c.    
     Due to the slant surface of the bottom of the guiding blocks and the flexible force of the spring  27 , the sliding blocks  222   a ,  222   c  slides along the slant guiding surface  214  of the connection base  21  (referring to  FIG. 2 ) and are out of the concave slots  213   a ,  213   c . When the sliding blocks  222   a ,  222   c  has an angle displacement to a pre-determined angle (in this embodiment, the angle is 15 degrees), two movements are generated. One is that the rotation locking flake  25  rotates with the same angle displacement. Another is that the convex portions  225  of the rotation sleeve  22  moves and is wedged into the concave portions  235  of the middle sleeve  23  (referring to  FIG. 2 ). The convex plate  221  of the rotation sleeve  22  temporarily is wedged with the bottom edge of the middle sleeve  23 . 
     Reference is made to  FIG. 5 , which shows the assembly cross-sectional diagram of a locking mechanism of the replaceable illumination module being in a lock status of according to an embodiment of the present invention. At this time, the hand of the user can leave the replaceable illumination module  2  for an embedded lamp. The connection base  21  moves downwards to the original location due to flexible force. The guiding blocks  232   a ,  232   c  moves to the top side of the concave slots  213   a ,  213   c . The sliding blocks  222   a ,  222   c  slides along the slant guiding surface  214  of the connection base  21  until the sliding blocks  222   a ,  222   c  enters into next concave slots  213   b ,  213   d  (referring to  FIGS. 2 , and  214   d  is not shown). At this time, the rotation sleeve  22  and the rotation locking flake  25  continuously rotates (in this embodiment, along the clockwise direction). The sliding blocks  222   b ,  222   d  moves to the concave slots  213   a ,  213   c  and contacts the guiding blocks  232   a ,  232   c.    
     Reference is made to  FIG. 6 , which shows the assembly perspective diagram of an embedded lamp. The rotation locking flake  25  and the top frame  14  are in a vertical status. The replaceable illumination module  2  is fastened in the lamp cover  10 . 
     When the user changes the replaceable illumination module  2 , the user pushes the replaceable illumination module  2  upwards. The sliding blocks of the rotation sleeve  22  leaves the concave slots again, and rotate along the clockwise direction. When the user feels that the convex plate  221  of the rotation sleeve  22  is temporarily wedged with the bottom edge of the middle sleeve  23 , the force is reduced to make the connection base  21  recover to the original location. Next, the rotation sleeve  22  and the rotation locking flake  25  continuously rotate to the unlock location. In other words, the rotation locking flake  25  can leave the opening  140  of the top frame  14 . Finally, the replaceable illumination module  2  moves downwards and leaves from the lamp cover  2 . 
     As shown in  FIGS. 7 and 8 . By utilizing the structure of the present invention, the lamp cover  10  for an embedded lamp can be assembled with different replaceable illumination modules  2 ,  2   a  for an embedded lamp. The replaceable illumination module  2  for an embedded lamp has a bulb  284 . The replaceable illumination module  2   a  for an embedded lamp has three LED lamps  285 . In this embodiment, the top surface of the replaceable illumination module  2  has a power supply connector  283  for connecting electrical wire. 
     The present invention provides replaceable illumination module  2  for an embedded lamp. Therefore, the user does not need to replace the lamp cover  10  and can be assembled with different light sources, such as power-saving bulb, LED, etc. The environment protection is achieved. Furthermore, the user can easily change the different illumination modules to meet the requirements, and does not need the change the total set of embedded lamp.
