On the basis of the above working process, the LED control circuit provided in this embodiment of the present application further provides a third power supply unit, and then a working process of the LED control circuit including the third power supply unit is described, and fig. 5 is a second working schematic diagram of the LED control circuit provided in this embodiment of the present application.
After the power supply unit is switched on, the power supply unit respectively supplies power to the first power supply unit, the second power supply unit and the third power supply unit. Wherein the third power supply unit supplies power to the wireless control unit.
The difference between the second operating structure diagram of the LED control circuit shown in fig. 5 and the first operating structure diagram of the LED control circuit shown in fig. 4 is that the power supply unit circuit for providing power to the wireless control unit is different, and the whole operating process is similar, and is not described herein again.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, releasably connected, or integral; may be mechanically coupled, may be electrically coupled or may be in communication with each other; either directly or indirectly through intervening media, such as through internal communication or through an interaction between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature in between. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
