 a color wheel module, wherein the color wheel module is detachably disposed in the main body, and the color wheel module comprises: 
 a color wheel; 
 a housing, wherein the color wheel is detachably disposed in the housing; 
 a daughter board for electrically connecting to the power supply and the coupling device; and 
 a motor for electrically connecting to the color wheel and for electrically connecting to the daughter board, the motor being adapted for driving the color wheel, 
 wherein the color wheel module transmits signal with the coupling device through the daughter board. 
 
     
     
       2. The device as claimed in  claim 1 , wherein the color wheel module further comprises:
 an index board for electrically connecting to the daughter board to determine color sectors of the color wheel. 
 
     
     
       3. The device as claimed in  claim 1 , wherein the daughter board and the motor are disposed with the housing, which is detachably disposed on the main body of the projection device. 
     
     
       4. The device as claimed in  claim 2 , wherein the daughter board, the motor, and the index board are disposed on the housing, which is detachably disposed on the main body of the projection device. 
     
     
       5. The device as claimed in  claim 3 , wherein the color module further comprises a handle spring disposed on the housing so that the color wheel module is adapted to be removed from the main body by applying an external force onto the handle spring. 
     
     
       6. The device as claimed in  claim 4 , wherein the color module further comprises a handle spring disposed on the housing so that the color wheel module is adapted to be removed from the main body by applying an external force onto the handle spring. 
     
     
       7. The device as claimed in  claim 1 , wherein the main body comprises a cover pivoting on a top portion of the main body, and the color wheel module is detachably disposed under the cover. 
     
     
       8. The device as claimed in  claim 1 , wherein the main body comprises a cover pivoting on a side area of the main body, and the color wheel module is detachably disposed under the cover. 
     
     
       9. The device as claimed in  claim 1 , wherein the main body comprises a cover pivoting on a bottom area of the main body, and the color wheel module is detachably disposed under the cover. 
     
     
       10. A color wheel module for a projection device, wherein the projection device comprises a main body, a power supply and a coupling device, the color wheel module comprising:
 a color wheel being detachably disposed in the main body; 
 a daughter hoard for electrically connecting to the power supply and the coupling device; and 
 a motor for electrically connecting to the color wheel and for electrically connecting to the daughter board, the motor being adapted for driving the color wheel, 
 wherein the color wheel module transmits signal with the coupling device through the daughter board. 
 
     
     
       11. The color wheel module as claimed in  claim 10 , wherein the color wheel module further comprises:
 an index board for electrically connecting to the daughter board to determine color sectors of the color wheel. 
 
     
     
       12. The color wheel module as claimed in  claim 10 , wherein the daughter board and the motor are disposed with the main body. 
     
     
       13. The color wheel module as claimed in  claim 11 , wherein the daughter board, the motor and the index board are disposed on the main body. 
     
     
       14. A color wheel module for a projection device, wherein the projection device comprises a main body, a power supply and a coupling device, the color wheel module is disposed on the main body, the color wheel module comprises:
 at least one peripheral element; 
 a color wheel being detachably disposed on the at least one peripheral element; 
 a daughter board for electrically connecting to the power supply and the coupling device; and 
 a motor for electrically connecting to the color wheel and for electrically connecting to the daughter board, the motor is adapted for driving the color wheel, 
 wherein the color wheel module transmits signal with the coupling device through the daughter board. 
 
     
     
       15. The color wheel module as claimed in  claim 14 , wherein the least one peripheral element comprises a housing, and the color wheel is detachably disposed in the housing. 
     
     
       16. The color wheel module as claimed in  claim 14 , wherein the color wheel module further comprises:
 an index board for electrically connecting to the daughter board to determine color sectors of the color wheel. 
 
     
     
       17. A projection device, comprising:
 a main body;   a power supply;   a coupling device; and   a color wheel module, wherein the color wheel module is detachably disposed on a cover of a top portion of the main body, and the color wheel module comprises:
 a color wheel; 
 a housing, wherein the color wheel is detachably disposed in the housing; 
 a daughter board electrically connected to the power supply and the coupling device, the daughter board supplying electrical power from the power supply to the color wheel module; and
