In the prior art, a dimming control mode applied to the field of home lighting generally utilizes an infrared or wireless technology to connect a remote controller and an LED lamp, so that the LED lamp is subjected to point-to-point dimming control through the remote controller; or the LED lamp is subjected to dimming control through a switch. The two dimming control modes are simple to operate and low in cost, but have the disadvantage of poor stability.
In addition, the requirements of the LED lamp applied in the field of sports lighting are generally sufficient brightness and uniform and stable illuminance, so the main technical center of gravity of the dimming control system is also in the aspects of stability and no stroboflash to the light source, no glare and brightness and light effect. This set of systems does not typically support mainstream dimming control protocols, such as the dmx512 protocol and dali protocol, which, although less costly, do not meet the light show requirements. If the requirement of the light show needs to be introduced to realize a certain light effect, another set of dimming control system needs to be introduced, and the set of dimming control system cannot be used as illumination. Therefore, if there is a light show demand, a large amount of cost resources need to be invested to build a platform, and two demands of one set of system cannot be realized with low cost.

The dimming driver adopts a PWM technology, and adjusts the constant current output according to the dimming driving command so as to drive the dimming output, thereby driving the brightness of the LED lamp.
In addition, after each dimming driver completes dimming the corresponding LED lamp, the state information can be uploaded to the dimming controller, and the state information represents the brightness information of the corresponding LED lamp; then, the dimming controller sends the state information to the touch screen; and finally, the touch screen displays the state information to inform a user.
In the embodiment, the dimming control system is upgraded, and the dimming control command is encoded by adopting the dimming protocol, so that the dimming control of the LED lamp can be realized by adopting the dimming protocol in the system which does not support the dimming protocol. Therefore, stable and efficient illumination can be provided, and cost resources can be saved.
Further, in the embodiment of the present invention, the dimming control command is a scene adjustment command or a light show command. The dimming control command may include address information of the dimming driver and brightness information of the corresponding LED lamp.

according to the dimming control command, acquiring address information of each dimming driver and first brightness information of the LED lamp corresponding to the dimming driver;
and coding the address information and the first brightness information by adopting a dimming protocol to obtain a dimming driving command corresponding to the dimming driver.
In this embodiment, a scene mode flag may be set in the scene adjustment command, and lights with different brightness may be adjusted respectively corresponding to four scene modes, such as a TV rebroadcasting scene mode, a competition scene mode, a training scene mode, and an entertainment scene mode.
For example, when the scene to be adjusted corresponding to the scene adjustment command is the training scene mode, address information and first brightness information of each dimming driver in the scene adjustment command are obtained, where the first brightness information corresponds to the training scene mode.
When the control command of adjusting luminance is the light show command, adopt the protocol of adjusting luminance right the control command of adjusting luminance is encoded, obtains the drive command of adjusting luminance, includes:
acquiring the running number of the light show according to the dimming control command;
operating a light show program corresponding to the operation number;
in the operation process, address information of each dimming driver and second brightness information of the LED lamp corresponding to the dimming driver are obtained;
and coding the address information and the second brightness information by adopting a dimming protocol to obtain a dimming driving command corresponding to the dimming driver.

It should be noted that the dimming controller processes the scene adjustment command and the light show command differently, and if the received scene adjustment command is the scene adjustment command, the dimming driving command sent to the dimming driver in each data receiving period is the same, and before the different scene adjustment commands are not received, the brightness of the original scene adjustment command is maintained, so that the stability of the illumination can be maintained. If a light show command is received, the dimming driving command sent by the dimming controller may change in each data receiving period, so that the LED lamp can realize various brightness changes in a short time, thereby showing the light show effect.
In this embodiment, on one hand, the dimming control command is encoded by using the dimming protocol through upgrading the dimming control system, so that the dimming control of the LED lamp can be performed by using the dimming protocol in a system that does not support the dimming protocol. On the other hand, the light show program corresponding to the operation number is operated, in the operation process, the address information of each dimming driver and the second brightness information of the LED lamp corresponding to the dimming driver are obtained, and the dimming protocol is adopted to code the address information and the second brightness information, so that the system can meet the light show requirement.
