Description:
This application claims the priority benefit of Taiwan patent application number 108144369, filed on Dec. 4, 2019. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to light-field technology and more particularly, to a method of using a dynamic light field system, which uses a controller to analyze the color of a picture file 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 light-emitting device 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 picture file, and then drives the at least one light-emitting device to emit light according to the analysis results, so that the light-emitting elements of the at least one light-emitting device continuously display multiple blocks in the picture file to create a dynamic light field effect. In this way, multiple light-emitting devices can display a dynamic light field according to a picture file. 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. 
     It is still another object of the present invention to provide a dynamic light field system, which enables a static picture file to be presented by a dynamic light field, so even if only one single picture file is used, the created light field can be rendered dynamic. 
     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 at least one light-emitting device  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 the 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, WiFi, wireless sensing network). 
     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. 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 device  2  can be a lamp post, a ceiling lamp, or a decorative lamp 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 picture file  3  where the processing module  11  uses a preset algorithm to compare the color pixels (RGB values) in the picture file  3  with the international color code table, and then analyzes the color pixels in the picture file  3  to find the corresponding plural international color codes, and then divides the picture file  3  into multiple blocks  30 . 
     (B) The processing module  11  of the controller  1  uses the internal timing unit  111  to add a transmission timing signal to the blocks  30  in the picture file  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 unit  21  of each of the at least one light-emitting device  2 . 
     (C) The transmission unit  21  of each of the at least one light-emitting device  2  receives the multiple international color codes and the timing signal and then transmits the multiple international color codes and the timing signal to the processing unit  22 , then the processing unit  22  performs light-emitting operations according to the multiple international color codes and the timing signal to drive the light-emitting elements  23 , so that the light-emitting elements  23  of the light-emitting device  2  continuously display the multiple blocks  30  in the picture file  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 device  2  displays a dynamic light field based on the picture file  3 . 
     In the above step (A), the picture file  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 file  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 blocks  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 step (A), the processing module  11  of the controller  1  can divide the picture file  3  into two, three, four, five or more than five blocks  30 , and each block  30  preferably contains multiple international color codes. However, in actual application, each block  30  can contain only one international color code. 
     When the present invention is actually used, the picture file  3  is an example of using a cloud picture file, and the processing module  11  of the controller  1  first performs a color analysis operation on the cloud picture file  3 . The processing module  11  compares the color pixels (RGB values) in the cloud picture file  3  with the international color code table, and then analyzes the color pixels in the cloud picture file  3  to find the corresponding plural international color codes and then divides the cloud picture file  3  into multiple blocks  30 . Then, the processing module  11  of the controller  1  adds a transmission timing signal to the blocks  30  and transmits the international color codes and the timing signal to the transmission unit  21  of each of the at least one light-emitting device  2  through the transmission module  12 . After received the multiple international color codes and the timing signal, the transmission unit  21  of each of the at least one light-emitting device  2  transmits the multiple international color codes and the timing signal to the processing unit  22 , then the processing unit  22  performs light-emitting operations according to the multiple international color codes and the timing signal to drive the light-emitting elements  23 , so that the light-emitting elements  23  of the light-emitting device  2  continuously display the multiple blocks  30  in the cloud picture file  3  according to the time arranged by the timing signal, and display the corresponding colors of the cloud picture file  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 cloud when it is floating. 
     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 file  3 , and then drives at least one light-emitting device  2  to emit light according to the analysis results, so that the light-emitting elements  23  of the light-emitting device  2  continuously display the multiple blocks  30  in the picture file  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 file  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. 
     3. The dynamic light field system enables a static picture file  3  to be presented by a dynamic light field, so even if only one single picture file  3  is used, the created light field can be rendered dynamic.
