To realize this function, it is necessary to rely on the existing dual-channel four-color temperature light switch module. Among them, this type of dual-channel four-color temperature light switch module generally adopts a single-contact design, that is: the user generates corresponding control instructions by single-click pressing on this contact to control the color temperature effects of the two LED light sources. And the changes of these different color temperatures generally follow a cyclic switch of different color temperature values. When a specific color temperature is required, the user often needs to press multiple times and judge whether the required specific color temperature is reached by visually observing the effect, and the operation is cumbersome and complex.

[0025] Based on the above circuit composition, a dual-channel multi-color-temperature dual-contact lighting switch circuit is formed. For the convenience of understanding, the working principles of the first touch module 6 and the second touch module 7 are further explained below with specific embodiments.

[0026] In this embodiment, the control module 5 controls the first LED unit 1 and the second LED unit 2 to sequentially cycle through the rated color temperatures in order based on the number of presses of the first touch module 6. Specifically, the rated color temperatures are 2200K, 3000K, 4000K, 5000K, and 4000K in order. At this time, the user can continuously click the touch key T1 of the first touch module 6 (each click, the first touch module 6 sends an input command to the control module 5). Correspondingly, the control module 5 sends corresponding color temperature adjustment commands to the first dimming module 3 and the second dimming module 4 respectively. The first dimming module 3 and the second dimming module 4 control the first LED unit 1 and the second LED unit 2 to sequentially cycle through to the rated color temperatures based on each color temperature adjustment command. That is, when the user presses the first touch module 6 multiple times, the first LED unit 1 and the second LED unit 2 sequentially switch to 2200K, 3000K, 4000K, 5000K, and 4000K respectively.

[0027] In this embodiment, the control module controls the brightness of the first LED unit and the second LED unit through the first dimming module and the second dimming module based on the duration of a single press of the first touch module. That is, the longer the duration of a single press, the brighter the first LED unit and the second LED unit are controlled to be; conversely, the longer the duration of a single press, the darker the first LED unit and the second LED unit are controlled to be. Those skilled in the art can adjust the brightness according to the actual pre-set rules according to the duration of the press, and no specific limitation is made here.

[0028] In this embodiment, the control module 5 controls the first LED unit 1 and the second LED unit 2 to preferentially switch to the rated reading color temperature based on the pressing situation of the second touch module 7. Specifically, the rated reading color temperature is 4000K. At this time, the user can click the touch key T2 of the second touch module 7 (each click, the second touch module 7 sends an input command to the control module 5). Correspondingly, the control module 5 sends corresponding color temperature adjustment commands to the first dimming module 3 and the second dimming module 4 respectively. The first dimming module 3 and the second dimming module 4 control the first LED unit 1 and the second LED unit 2 to switch to the rated reading color temperature based on the color temperature adjustment command. That is, when the user clicks the second touch module 7, the first LED unit 1 and the second LED unit 2 switch to 4000K correspondingly.

[0029] By adopting the different triggering functions corresponding to the above-mentioned first touch module 6 and second touch module 7, especially when the user clicks the second touch module 7, the first LED unit 1 and the second LED unit 2 will preferentially switch to the rated reading color temperature, achieving the effect of rapid color temperature switching and improving the user experience. In addition, the dual-channel multi-color temperature dual-contact lighting switch circuit of this embodiment also has a high degree of integration and modular design, which is convenient for later maintenance and upgrade.

[0030] In terms of hardware configuration, the processor U1 can adopt a high-performance microprocessor, such as the ARM Cortex-M series. These processors have the characteristics of low power consumption and high performance, while the processors U3 and U4 can adopt high-performance power integrated circuits, which can meet the real-time and stability requirements of the control module 5 and the dimming module in this embodiment.

[0031] In terms of software design, the control module 5, the first dimming module 3 and the second dimming module 4 can be programmed and controlled through embedded software to realize functions such as color temperature switching and brightness adjustment. At the same time, by optimizing the algorithm, the response speed and accuracy of color temperature switching can be improved, the gradient and smoothness of brightness change when the button is long-pressed can be realized, and the directional or cyclic brightness adjustment mode can be set to further improve the user experience.

[0032] In addition, the dual-channel multi-color temperature dual-contact lighting switch circuit of this embodiment also has a wide range of application prospects. For example, in the field of home lighting, users can quickly switch the color temperature according to different scenarios and needs to create a comfortable and warm lighting environment. In the field of commercial lighting, the circuit of this embodiment can be used for lighting control in places such as shopping malls, hotels, and offices to meet the lighting needs in different scenarios.

[0033] In short, the dual-channel multi-color temperature dual-contact lighting switch circuit of this embodiment realizes functions such as rapid color temperature switching and brightness adjustment, providing users with a more convenient and comfortable lighting experience. At the same time, the circuit also has a high degree of integration and modular design, which is convenient for later maintenance and upgrade, and has broad application prospects.
