[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0038] like Figure 1 As shown, this disclosure provides a lighting control device, including: a main control module 1 and at least one drive module 2; any drive module can be connected to either of two light sources; the two light sources include: an RGB type light-emitting diode lamp group and an RGBIC type light-emitting diode lamp group; each lamp group includes at least one light-emitting diode;

[0039] The main control module is configured to determine the type of light source connected to each driver module based on the configuration information; determine the control signal for driving the light source based on the type of light source connected to each driver module and the control command for the light source; and send the control signal to the driver module.

[0040] The driver module is configured to drive the light source according to the received control signals.

[0041] The lighting control device provided in this application embodiment allows any one of two types of light sources (RGB LED light-emitting diode groups and RGBIC LED light-emitting diode groups) to be connected to any one of them. The main control module of the lighting control device determines the type of light source connected to each driver module based on the configuration information, determines the control signal to drive the light source based on the type of light source connected to each driver module and the control command for the light source, and sends the control signal to the driver module. The lighting control device provided in this application embodiment can adapt to two types of light sources with a single control device, thereby improving the versatility of the lighting control device and saving users' operating costs.

[0042] In one exemplary embodiment, the configuration information includes the configuration of the driving modes for multiple light sources; wherein each driving module drives one light source.

[0043] The driving modes include: unified driving mode and individual driving mode;

[0044] The unified driving mode supports driving multiple light sources of the same type using the same driving signal;

[0045] The individual drive mode supports driving each light source with an independent drive signal.

[0046] In one exemplary embodiment, the configuration information includes configuration parameters for multiple light emission effect modes of at least one light source.

[0047] When lighting control devices are used to drive ambient lights, the lighting effect modes of the ambient lights can be designed and adjusted according to different application scenarios and user needs. Here are some lighting effect modes: static color, dynamic flowing water, music rhythm, and environmental perception.

[0048] Multiple driver modules can drive multiple light sources. Each driver module supports individual connection to either RGB or RGBIC LED groups. The driving mode for multiple light sources can be configured as a unified driving mode or an individual driving mode. The unified driving mode supports using the same driving signal to drive multiple light sources of the same type, thereby achieving the same lighting effect. The individual driving mode supports using an independent driving signal to drive each light source, thereby achieving different lighting effects for multiple light sources. All light sources can be RGB LED groups, or all RGBIC LED groups. Alternatively, some light sources can be RGB LED groups, and others can be RGBIC LED groups.

[0049] A lighting control device can simultaneously adapt to two types of light sources (RGB and RGBIC). For manufacturers, this reduces design and manufacturing costs. For users, it allows them to retain existing RGBIC or RGB LED light groups and then expand with new RGB LED and / or RGBIC LED light groups, reducing purchase and upgrade costs.

Cascading these two devices allows for compatibility with light source loads from more manufacturers, supporting longer light strip (or string) lengths and higher wattages. Many manufacturers also have simple switch control signal outputs, which can be used as input signals for the aforementioned input module, thus enriching the input control signals of the lighting control device of this application.
