     Preferably, the controller  1  and the plurality of light emitting devices  2  can be electrically connected to an external power supply through a power transmission line (not shown in FIG-S.  1  and  2 ), so as to supply power to the controller  1  and the plurality of light emitting devices  2  through the external power source. In an embodiment, the power transmission line can be a power plug, and the external power supply can be a commercial power socket or a power supply socket of a power generator; however, in actual application, the controller  1  and the plurality of light emitting devices  2  can be electrically connected to an external portable power storage device (such as a power bank) through a USB power transmission line. It should be noted that there are many known manners and structures to supply power to the controller  1  and the light emitting devices  2 , but the details of known power supply manners and structures are not the key feature of the present invention, so detailed description is not repeated herein. 
     In practical use, the dynamic light field system of the present invention can be applied to a game room, a living room or a bedroom, etc.; the controller  1  can be disposed in the room, the two front lights  2 A of the light emitting devices  2  can be disposed on the left and right sides of the front part of the room, and the two rear light  2 B of the light emitting devices  2  can be disposed on the left and right sides of the rear part of the room, and the perception zone  20  is formed among the two front lights  2 A and the two rear lights  2 B. A user can stand or sit in a seat to be located in the perception zone  20 , and use an electronic device (such as a smartphone, a tablet, a laptop or a desktop computer) to communicate with the transmission module  12  of the controller  1 ; for example, through the electronic device, the user can select the dynamic light field to be presented, such as a dynamic light field of breathing light, flame or sea. After the controller  1  receives the signal transmitted from the electronic device, the controller  1  can transmit the color signal and the timing signal to the transmission module  12  through the processing module  11  and the timing unit  111 ; the transmission module  12  of the controller  1  then transmits the color signal and the timing signal to the transmission units  22  of the light emitting devices  2 , and the transmission unit  22  of each light emitting device  2  then transmits the color signal and the timing signal to the corresponding light sources  21 , to enable the light sources  21  to emit light based on the received color signal and timing signal, so that the light sources  21  of the light emitting devices  2  can emit light in a continuous manner. Therefore, the controller  1  and the light emitting devices  2  can create the dynamic light field to make the user located in the perception zone  20  feel the dynamic light field, thereby achieving the effect of immersive experience. 
     In an embodiment, the above-mentioned electronic device can also transmit at least one image file to the processing module  11  of the controller  1 , and the processing module  11  compares color pixels (such as RGB values) in the image file with an international color code table by a preset algorithm, to analyze and obtain the color signals of the international color codes corresponding to the color pixels in the image file, and the processing module  11  of the controller  1  then uses the timing unit  111  to add the color signals of the international color codes into the timing signal to be transmitted, and then transmits the color signals and the timing signal to the transmission module  12 , so that the color signals and the timing signal can be transmitted to the transmission units  22  of the light emitting devices  2  through the transmission module  12 . After the transmission units  22  of the light emitting devices  2  receive the color signals and the timing signal, each transmission unit  22  transmits the received color signals and the timing signal to the corresponding light sources  21 , so that the light sources  21  of each light emitting device  2  can emit light based on the color signals and the timing signal, to display the corresponding colors based on the time slots scheduled by the timing signal. Compared with the conventional technology, the controller  1  and the light emitting devices  2  of the present invention can continuously create and present the dynamic light field based on at least one image file, so that the user is not limited to the dynamic light field built in the program of the electronic device, and the diversity of the light field in use can be improved. In the dynamic light field system of the present invention, the user can use the image file to create and present the dynamic light field, and the difficulty in producing the dynamic light field can be reduced, thereby achieving the effect of improving convenience in production and use.
