 wherein the lighting control result data is based on a lighting identification number and control result information of a light source. 
 
     
     
       2. The apparatus of  claim 1 , wherein the power reserve stage issuer transmits the power reserve stage information every minimum allowable time span when the power reserve stage is lower than an alert stage, every medium allowable time span when the power reserve stage is between the alert stage and a stable stage, and every maximum allowable time span when the power reserve stage is higher than the stable stage. 
     
     
       3. The apparatus of  claim 2 , wherein the lighting control result data includes information on a control result transmission location, a control result received time, and a control result value. 
     
     
       4. The apparatus of  claim 3 , wherein the lighting control result receiver is configured to compare the control result received time with the current time either to check the lighting control result data when the control result received time and the current time are equal, or to ignore the lighting control result data when the control result received time and the current time are not equal. 
     
     
       5. The apparatus of  claim 4 , further comprising a lighting control result database configured to store and manage the lighting control result data. 
     
     
       6. The apparatus of  claim 5 , wherein the power reserve stage determination unit calculates a variation of the control result value by checking a previous control result value received from the control result transmission location, and determining the power reserve stage information based on the variation. 
     
     
       7. A lighting controller, comprising:
 a power reserve stage receiver configured to receive, from an integrated lighting control apparatus, power reserve stage information based on a power reserve stage; 
 a lighting soft switch unit configured to control a brightness of a light source according to lighting control information corresponding to the received power reserve stage information; and 
 a lighting control result transceiver configured to receive, from the light source, a lighting identification number and control result information corresponding to the light source, to generate lighting control result data by integrating the lighting identification number and the control result information, and to transmit the lighting control result data to the integrated lighting control apparatus. 
 
     
     
       8. The lighting controller of  claim 7 , wherein the lighting controller dims the light source using the lighting soft switch unit when the power reserve stage is lower than an alert stage, and applies standby power to the lighting soft switch unit to prepare for a case where the power reserve stage becomes lower when the power reserve stage is in between the alert stage and a stable stage. 
     
     
       9. The lighting controller of  claim 8 , wherein the lighting control result transceiver transmits lighting dimming control information of the light source, in line with the lighting control result data, to the integrated lighting control apparatus when the power reserve stage is lower than the alert stage. 
     
     
       10. The lighting controller of  claim 8 , wherein the lighting controller does not apply standby power to the lighting soft switch unit when the power reserve stage is equal or higher than the stable stage. 
     
     
       11. A method for integrated lighting control, comprising:
 receiving, by an integrated lighting control apparatus, lighting control result data generated according to a lighting identification number and control result information of a light source; 
 determining, by the integrated lighting apparatus, power reserve stage information based on the received lighting control result data; and 
 transmitting, by the integrated lighting control apparatus, the power reserve stage information to a lighting controller. 
 
     
     
       12. The method of  claim 11 , wherein the transmitting comprises transmitting the power reserve stage information every minimum allowable time span when a power reserve stage corresponding to the power reserve stage information is lower than an alert stage, every medium allowable time span when the power reserve stage is between the alert stage and a stable stage, and every maximum allowable time span when the power reserve stage is higher than the stable stage. 
     
     
       13. The method of  claim 12 , wherein the lighting control result data includes information on a control result transmission location, a control result received time, and a control result value. 
     
     
       14. The method of  claim 13 , wherein the receiving comprises comparing the control result received time with a current time either to check the lighting control result data when the control result received time and the current time are equal, or to ignore the lighting control result data when the control result received time and the current time are not equal. 
     
     
       15. The method of  claim 14 , further comprising storing and managing the lighting control result data. 
     
     
       16. The method of  claim 15 , wherein determining the power reserve stage information comprises calculating a variation of the control result value by checking the previous control result value received from the control result transmission location, and determining the power reserve stage information based on the variation. 
     
     
       17. The method of  claim 16 , further comprising:
 receiving, by the lighting controller, the power reserve stage information; 
 generating, by the lighting controller, the lighting control result data by integrating the lighting identification number and the control result information received from the light source; and

       18. The method of  claim 17 , further comprising:
 performing, by the lighting controller, dimming of the light source using the lighting soft switch unit when the power reserve stage is lower than the alert stage and applying, by the lighting controller, standby power to the lighting soft switch unit to prepare for a case where the power reserve stage becomes lower when the power reserve stage is in between the alert stage and the stable stage. 
 
     
     
       19. The method of  claim 18 , further comprising:
 transmitting, by the lighting controller, in line with the lighting control result data, lighting dimming control information of the light source to the integrated lighting control apparatus when the power reserve stage is lower than the alert stage. 
 
     
     
       20. The method of  claim 18 , further comprising:
 not applying, by the lighting controller, standby power to the lighting soft switch unit when the power reserve stage is equal or higher than the stable stage.
