     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to light-field technology and more particularly, to a dynamic light field system and its method of use, which uses a controller to analyze the color of multiple picture files and drive multiple light-emitting devices to project light outward based on the color analysis results, thereby creating a dynamic light field effect. 
     2. Description of the Related Art 
     Today&#39;s lighting system is getting more and more advanced. LED lighting has the advantages of adjustable dimming function, low power consumption, small size, being not easy to break or damage, and long service life. Therefore, LED lighting systems will continue to spread. As the current lighting system is advanced, flexible and more integrated, the light system in many fields (such as: game industry, retail industry, hotel industry or home filed, etc.) will enhance the experience through the lighting system, thereby improving productivity, safety, efficiency and leisure. 
     Furthermore, in order to enhance the light lighting experience, some manufacturers use programs to control the LED lighting system to change the color and lighting time of the LEDs, and then create a light scene (for example, to create scenes such as torches or the sea). However, the conventional light scene setting needs to be written in the program in advance by the manufacturer, and then provided to the user to choose to use, so the user&#39;s choice will be limited to the scene in the program. For users, it is very unattractive, and the scene cannot be adjusted according to their own preferences, resulting in loss of willingness to buy. 
     SUMMARY OF THE INVENTION 
     The present invention has been accomplished under the circumstances in view. It is a first object of the present invention to provide a dynamic light field system, which comprises a controller comprising a processing module, a transmission module and a power supply device, and a plurality of light-emitting devices each comprising a transmission unit, a processing unit, a plurality of light-emitting elements and a power supply unit. The processing module of the controller first performs a color analysis operation on a plurality of picture files to compare the color pixels (RGB values) in the picture files with the international color code table and then analyze the color pixels in the picture files to find the corresponding plural international color codes. Then, the processing module of the controller uses the internal timing unit to add a timing signal to the picture files, and transmits the international color codes and the timing signal to the transmission modules of the light-emitting devices, enabling the transmission modules to transmit the multiple international color codes and the timing signal to the respective transmission units. Then, the processing units perform light-emitting operations according to the multiple international color codes and the timing signal to drive the respective light-emitting elements, so that the light-emitting elements of the light-emitting devices continuously play the picture files according to the time arranged by the timing signal, and display the corresponding colors according to the multiple international color codes, and thus, the light-emitting devices displaying a dynamic light field based on the picture files. Because the effect of the dynamic light field can be created by the multiple light-emitting elements of the multiple light-emitting devices, the dynamic light field system increases the diversity of use and reduces the difficulty of dynamic light field production, thereby achieving the purpose of improving the convenience of overall production and use. 
     It is another object of the present invention to provide a dynamic light field system, wherein the timing unit of the processing module can be controlled by an electronic device, and the timing can be changed by the electronic device, thereby adjusting the time for the bright display of the multiple light-emitting elements to improve the variability during use, so as to achieve the effect of increasing market competitiveness. 
     Other advantages and features of the present invention will be fully understood by reference to the following specification in conjunction with the accompanying drawings, in which like reference signs denote like components of structure.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to  FIGS. 1-7 , a dynamic light field system in accordance with the present invention comprises a controller  1  and a plurality of light-emitting devices  2 . 
     The controller  1  comprises a processing module  11  with a timing unit  111  arranged therein, a transmission module  12  electrically connected to one end of the processing module  11 , and a power supply device  13  electrically connected to an opposite end of the processing module  11  to provide power for the operation of the controller  1 . 
     The light-emitting device  2  comprises a transmission unit  21  that can receive the signal transmitted by the transmission module  12 , a processing unit  22  electrically connected with one end thereof to the transmission unit  21 , a plurality of light-emitting elements  23  (such as light-emitting diodes) arranged in an array and electrically connected to an opposite end of the processing unit  22  for emitting multiple colors of light, and a power supply unit  24  adapted to provide power for the operation of the light-emitting device  2 . 
     The transmission module  12  of the controller  1  and the transmission unit  21  of each light-emitting device  2  can be a wired transmission interface or a wireless transmission interface for mutual signal transmission. The wired transmission interface can be a wired connection interface such as USB (universal serial bus), micro-USB, mini-USB, etc. The wireless transmission interface can be a short-range communication device (such as Bluetooth module or WiFi module). 
     Furthermore, the power supply device  13  of the controller  1  and the power supply unit  24  of the light-emitting device  2  can be electrically connected to an external power source using a power transmission line (not shown; such as a power plug, etc.). The external power source can be a city power socket or a generator power socket that provides the power required by the controller  1  and the light-emitting device  2 . But in practical applications, it can also be connected to an external portable power storage device through a USB power transmission line (such as a portable charger). However, there are many ways and structures for the controller  1  and the light-emitting device  2  to obtain electric energy. It only needs to provide electric energy to the controller  1  and the light-emitting device  2 , and the detailed composition of the structure is not the main point of the invention and will not be repeated here. 
     The above-mentioned light-emitting devices  2  can be lamp posts, ceiling lamps, or decorative lamps set on the edge of a chair cushion, etc., which can project light outward. 
     When the method of using the dynamic light field system of the present invention is actually executed, it includes the following steps: 
     (A) The dynamic light field system uses the processing module  11  of the controller  1  to perform a color analysis on a plurality of picture files  3  where the processing module  11  uses a preset algorithm to compare the color pixels (RGB values) in each picture file  3  with the international color code table, and then analyzes the color pixels in each picture file  3  to find the corresponding plural international color codes. 
     (B) The processing module  11  of the controller  1  uses the internal timing unit  111  to add a transmission timing signal to the picture files  3 , and transmits the international color codes and the timing signal to the transmission module  12 , enabling the transmission module  12  to transmit the multiple international color codes and the timing signal to the transmission units  21  of the light-emitting devices  2 . 
     (C) The transmission units  21  of the light-emitting devices  2  receive the multiple international color codes and the timing signal and then transmit the multiple international color codes and the timing signal to the respective processing units  22 , then the processing units  22  perform light-emitting operations according to the multiple international color codes and the timing signal to drive the respective light-emitting elements  23 , so that the light-emitting elements  23  of the light-emitting devices  2  continuously display the picture files  3  according to the time arranged by the timing signal, and display the corresponding colors according to the multiple international color codes. In this way, the light-emitting devices  2  display a dynamic light field based on the picture files  3 . 
     In the above step (A), the picture files  3  can be transmitted to the processing module  11  of the controller  1  by an electronic device (such as a desktop computer, a notebook computer or a tablet computer, etc.). The electronic device can be installed with a default application program or a mobile application program, so that the picture files  3  to be transmitted can be selected through the default application program or the mobile application program. In step (B), you can adjust the interval timing between the multiple picture files  30 , and then change the light display time of the light-emitting elements  23 , and the timing is greater than zero seconds. 
     Furthermore, in the above-mentioned dynamic light field display, the plurality of light-emitting devices  2  can individually display a set of picture files  3 , and then the multiple light-emitting devices  2  can cooperate with each other to display and create a dynamic light field. But in practical application, the plurality of light-emitting devices  2  can display a set of picture files  3  together, and the plurality of light-emitting devices  2  can be used to continuously play the picture files  3 . In this way, a dynamic light field is displayed and created by continuously playing multiple picture files  3 . 
     When the present invention is actually used, the plurality of picture files  3  are used as an example of showing the swinging of the grass. The processing module  11  of the controller  1  first performs a color analysis operation on the grass-swinging picture files  3 . The processing module  11  compares the color pixels (RGB values) in the grass-swinging picture files  3  with the international color code table, and then analyzes the color pixels in the grass-swinging picture files  3  to find the corresponding plural international color codes. Then, the processing module  11  of the controller  1  adds a transmission timing signal to the grass-swinging picture files  3  and transmits the international color codes and the timing signal to the transmission units  21  of the light-emitting devices  2  through the transmission module  12 . After received the multiple international color codes and the timing signal, the transmission units  21  of the at least one light-emitting devices  2  transmit the multiple international color codes and the timing signal to the respective processing units  22 , then the processing units  22  perform light-emitting operations according to the multiple international color codes and the timing signal to drive the respective light-emitting elements  23 , so that the light-emitting elements  23  of the light-emitting devices  2  continuously play grass-swinging picture files  3  according to the time arranged by the timing signal, and display the corresponding colors of the grass-swinging picture files  3  according to the multiple international color codes. In turn, multiple light-emitting devices  2  can be used to create and show the dynamic light field of the grass when it is swinging. Furthermore, the above-mentioned user can change the timing through an electronic device to control the swing speed of the grass displayed by multiple light-emitting devices  2 . 
     The present invention has the following advantages: 
     1. The processing module  11  of the controller  1  first performs a color analysis operation on the picture files  3 , and then drives the light-emitting devices  2  to emit light according to the analysis results, so that the light-emitting elements  23  of the light-emitting devices  2  continuously play the picture files  3  to create a dynamic light field effect. Compared with the conventional technology, users are not limited to the use of the built-in dynamic light field in the program, so as to increase the diversity of use, and only need to use the picture filed 3 to present the dynamic light field. It can reduce the difficulty of dynamic light field production, thereby achieving the effect of improving the overall production and convenience of use. 
     2. The timing unit  111  of the processing module  11  can be controlled by an electronic device, and the timing can be changed by the electronic device, thereby adjusting the time for the bright display of the multiple light-emitting elements  23  to improve the variability during use, so as to achieve the effect of increasing market competitiveness.
