Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The present invention provides a lighting control device to solve the technical problem that the amount of energy consumed by the lighting control device increases due to the lighting control device being in a standby state for a long time.

[0047] Figure 1 FIG. 1 is a schematic diagram of a lighting control device according to an exemplary embodiment of the present invention. Figure 1 As shown, the lighting control device 100 provided in this embodiment includes: a controllable switch module 101 , a control module 102 , a signal module 103 and a power conversion module 104 .

[0048] In the lighting control device, the input end of the controllable switch module 101 is used to connect to the output end of the power module, the output end of the controllable switch module 101 is connected to the power end of the control module 102, the power end of the signal module 103 is connected to the output end of the power conversion module 104, the input end of the power conversion module 104 is used to connect to the output end of the power module, and the first end of the signal module 103 is connected to the control end of the controllable switch module 101.

[0049] Among them, the signal module 103 is used to send a first control signal to the controllable switch module 101, and to send a second control signal to the control module 102, so that the controllable switch module 101 generates a first power signal under the control of the first control signal, so that the control module 102 cuts off the circuit connection between the power module and the lighting device under the joint control of the second control signal and the first power signal.

[0050] Alternatively, the signal module 103 is used to send a third control signal to the controllable switch module 101 and to send a fourth control signal to the control module 102, so that the controllable switch module 101 generates a second power signal under the control of the third control signal, so that the control module establishes a circuit connection between the power module and the lighting device under the joint control of the fourth control signal and the second power signal.

[0051] When the power module needs to provide power to the lighting device, the signal module 103 sends a third control signal to the controllable switch module 101, and the controllable switch module 101 generates a second power signal under the third control signal. The second power signal acts on the power end of the control module 102, and the signal module 103 also sends a fourth control signal to the control end of the control module 102.

[0052] When the power module needs to stop supplying power to the lighting device, the signal module 103 sends a first control signal to the controllable switch module 101, and the controllable switch module 101 generates a first power signal under the first control signal. The first power signal acts on the power end of the control module 102, and the signal module 103 also sends a second control signal to the control end of the control module 102.

Under the joint action of the second power signal and the fourth control signal, the control module 202 closes the circuit between the power module and the lighting device to enable the power module to provide power to the lighting device.

[0058] When the power module needs to stop supplying power to the lighting device, the signal module 203 sends a first control signal to the controllable tube 201. Under the first control signal, the controllable tube 201 is in a cut-off working state and generates a first power signal. The first power signal acts on the power terminal of the control module 202, so that the control module 202 is in a non-working state. The signal module 203 also sends a second control signal to the control terminal of the control module 202. Under the combined action of the first power signal and the second control signal, the control module 202 disconnects the circuit between the power module and the lighting device, so that the power module stops supplying power to the lighting device.

[0063] When the power module needs to stop providing power to the lighting device, the user sends a second radio request signal to the receiving unit via radio transmission, wherein the second radio request signal is used to instruct the lighting control device to disconnect the circuit between the power module and the lighting device.

[0080] When the receiving module U3 receives the second radio request signal, that is, requests the lighting control device to switch from the working mode to the standby mode, the microprocessor module generates a high-level signal to the control module according to the radio request signal, so that the control module U5 does not work, and at the same time generates a high-level signal to the controllable switch module, so that Q3 is in the cut-off state, the controllable switch module does not work, and the lighting control device is in the standby mode.

[0081] When the receiving module U3 receives the first radio request signal, that is, the signal requesting the lighting control device to switch from the standby mode to the working mode, the microprocessor module generates a low-level signal to the control module according to the first radio request signal, and at the same time generates a low-level signal to the controllable switch module, so that Q3 is in the on state, the controllable switch module works and provides power to the control module, and the control module works, so that the lighting control device is in the working mode.

[0082] Because when the lighting control device is in standby mode, the controllable switch module and the control module U5 are not working, the control module is in a non-working state, and the controllable switch module is in a power-off state, thereby reducing the energy consumption of the lighting control device.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
