[0054] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0055] like Figure 1 and Figure 2 As shown, this application provides a lighting control device, including a base plate 1, a first housing 2, a control circuit board 3, and a second housing 4.

[0056] Specifically, the base plate 1 serves as the basic support structure for the lighting control device. The first housing 2 and the base plate 1 are sealed together to form a first sealed cavity 21. Inside this cavity is a control circuit board 3, which integrates electronic components for controlling the courtyard lighting fixtures, such as a microprocessor, relays, and signal processing modules. By placing the control circuit board 3 within the first sealed cavity 21, moisture and dust from the external environment are effectively isolated, thereby improving the moisture-proof and humidity-resistant performance of the control circuit board 3 and ensuring its long-term stable operation in the high-humidity environment of the courtyard. The second housing 4 is detachably connected to the base plate 1 and together with the base plate 1 forms a second sealed cavity 41. The second sealed cavity 41 is located on one side of the first sealed cavity 21 and contains a terminal block circuit board 5. The terminal block circuit board 5 has terminals for connecting external power lines. The terminal block circuit board 5 is electrically connected to the control circuit board 3 via wires, thus achieving electrical connection between the external power supply and the control circuit board 3. The second sealing cavity 41 not only provides an independent protective space for the terminal block circuit board 5, but also facilitates the separate disassembly and repair of the terminal block circuit board 5 during maintenance without opening the first sealing cavity 21, further improving the maintenance convenience and overall reliability of the device. Furthermore, the first sealing cavity 21 and the second sealing cavity 41 are isolated by a sealing structure, ensuring that their environments do not interfere with each other, thereby further enhancing the overall protective performance of the device.

[0057] like Figure 2 and Figure 3 As shown, in one specific embodiment of this application, the lighting control device includes an antenna assembly 6 for wireless communication. The first housing 2 has an antenna mounting hole, through which the antenna assembly 6 passes. The antenna assembly 6 includes an antenna 61, an antenna sheath 62, and an antenna housing 63. One end of the antenna 61 is electrically connected to the wireless communication module on the control circuit board 3 for receiving and transmitting control signals; the other end extends to the outside of the first housing 2 to facilitate signal propagation and reception, thereby improving the communication range and stability of the lighting control device. The antenna sheath 62 is made of insulating material and is tightly fitted around the outside of the antenna 61, providing mechanical support for the antenna 61 and also serving as insulation and protection to prevent damage to the antenna 61 due to external environmental influences. The antenna housing 63 is fixed to the antenna mounting hole by a snap-fit ​​mechanism and fitted around the outside of the antenna sheath 62. A sealing structure, such as a sealing ring or sealant, is used between the antenna housing 63 and the antenna mounting hole to ensure good waterproof sealing performance at the connection between the antenna assembly 6 and the first housing 2. This prevents moisture or dust from entering the first sealed cavity 21 through the antenna mounting hole, thereby ensuring the long-term stable operation of the control circuit board 3. While realizing wireless communication functionality, the antenna assembly 6 can also effectively adapt to the high humidity environment of the courtyard, ensuring the overall reliability and durability of the lighting control device.

[0058] like Figure 2 and Figure 3 As shown, in a specific embodiment of this application, the lighting control device includes a circuit reset assembly 7 for resetting the control circuit board 3. The circuit reset assembly 7 includes a circuit reset button 71, a waterproof plug 72, and a handle 73. The circuit reset button 71 is directly connected to the control circuit board 3 and has internal reset contacts for sending a reset signal to the control circuit board 3 upon triggering, thereby restoring the system to its initial state. One end of the waterproof plug 72 is fixed to a slot in the first housing 2 via a snap-fit ​​mechanism, forming a seal between the plug and the slot to prevent external moisture or dust from entering the first sealed cavity 21; the other end is tightly fitted around the outside of the circuit reset button 71, providing isolation and protection to ensure the normal operation of the circuit reset button 71 in high-humidity environments. The handle 73 is mounted on the handle mounting hole of the first housing 2 via a movable connection. One end extends to the outside of the first housing 2, facilitating manual triggering of the reset function by the user; the other end contacts the waterproof plug 72, and a pressing action transmits force to the waterproof plug 72, thereby triggering the circuit reset button 71. The combination of handle 73 and waterproof plug 72 enables indirect triggering of the circuit reset button 71, avoiding direct exposure to the external environment and further enhancing the waterproof sealing performance of the device. Furthermore, the movable connection of handle 73 allows it to automatically return to its original position after the reset operation, reducing mechanical wear and extending the service life of the circuit reset assembly 7.

[0059] like Figure 2 and Figure 3 As shown, in one specific embodiment of this application, the lighting control device further includes an indicator light assembly 8 for displaying the operating status of the device. The indicator light assembly 8 includes an indicator light 81 and a waterproof lampshade 82. The indicator light 81 is electrically connected to the signal output terminal on the control circuit board 3 via a wire, and is used to emit corresponding light signals according to the operating status of the control circuit board 3, such as constant light, flashing, or color change, to intuitively reflect the operating status or fault information of the device. The waterproof lampshade 82 is made of transparent or semi-transparent material, fitted over the indicator light 81, and fixed to the indicator light hole on the first housing 2 by a snap-fit ​​method. The edge of the waterproof lampshade 82 is provided with a sealing structure, such as a sealing ring or sealant, to ensure good waterproof sealing performance at the connection between it and the indicator light hole, preventing moisture or dust from entering the first sealed cavity 21 through the indicator light hole, thereby ensuring the long-term stable operation of the indicator light 81 and the control circuit board 3.

[0060] like Figure 4 and Figure 5As shown, in one specific embodiment of this application, the terminal block circuit board 5 includes an input port 51 and an output port 52, both of which are arranged on the same side of the terminal block circuit board 5. The input port 51 is used to connect to an upstream circuit, and the output port 52 is used to connect to an electrical load. By concentrating the input port 51 and the output port 52 on the same side of the terminal block circuit board 5, not only is the space occupied during wiring reduced, but also the potential for wire crossing or confusion during wiring is avoided, thus reducing the complexity of installation and maintenance.

[0061] like Figure 4 and Figure 5 As shown in one specific embodiment of this application, the terminal block circuit board 5 is further provided with a circuit fuse 9 to provide overcurrent protection. The circuit fuse 9 is connected in series in the power input circuit of the terminal block circuit board 5. It has a fuse structure inside. When the current in the circuit exceeds a preset threshold, the fuse structure will melt due to overheating, thereby cutting off the circuit and preventing excessive current from damaging the control circuit board 3 or other electronic components. The circuit fuse 9 adopts a replaceable design. Its two ends are fixed to the terminal block circuit board 5 by plugging or soldering, which facilitates quick replacement after melting and restores the normal working state of the circuit.

[0062] like Figure 4 and Figure 5 As shown in a specific embodiment of this application, the base plate 1 has a wire-passing boss 11 to guide and protect the access of external wires. The wire-passing boss 11 is a structure protruding from the surface of the base plate 1, and has a wire-passing hole 12 inside. One end of the wire-passing hole 12 communicates with the second sealed cavity 41, and the other end communicates with the external environment, forming a channel for the wire to enter the second sealed cavity 41. After the external wire enters the second sealed cavity 41 through the wire-passing hole 12, it is electrically connected to the connection terminal on the terminal block circuit board 5, thereby realizing the electrical connection between the external power supply and the lighting control device. The wire-passing boss 11 provides mechanical support and protection for the external wire, reducing the risk of damage to the wire caused by external pulling or bending.

[0063] like Figure 4 and Figure 5 As shown, in a specific embodiment of this application, the threaded hole 12 is specifically a threaded hole for threaded connection with an external conduit connector. The threaded structure of the threaded hole 12 allows the conduit connector to be fixed to the threaded boss 11 by tightening, thereby forming a stable mechanical connection. The threaded connection not only enhances the bonding strength between the conduit connector and the threaded hole 12, but also achieves a waterproof sealing effect through the tight fit between the threads, effectively preventing moisture or dust from entering the second sealing cavity 41 through the threaded hole 12.

[0064] like Figure 6As shown, the lighting control device of this application sends control signals to the lighting control device via a mobile APP or other mobile terminal during use. The control signals are transmitted wirelessly to the antenna assembly 6 of the lighting control device, and then received by the antenna assembly 6 and transmitted to the wireless communication module on the control circuit board 3. The wireless communication module converts the received Bluetooth signal or other wireless signal into a wired electrical signal and outputs it to an external wire through the connection terminal on the terminal block circuit board 5. The lighting fixture connected to the lighting control device via a wire is equipped with a decoder / encoder to decode the received wired electrical signal and control the power drive module inside the lighting fixture to work according to the decoded signal, thereby realizing functions such as switching the lighting fixture on and off, adjusting brightness, or changing color. When it is necessary to reset the lighting control device, the user can press the circuit reset button 71 on the device. After the circuit reset button 71 is triggered, it sends a reset signal to the control circuit board 3. The control circuit board 3 performs a reset operation according to the reset signal, restoring the device to its initial state. Through the above workflow, the lighting control device realizes the conversion and control of wireless and wired signals, and provides a convenient reset function through the circuit reset button 71, ensuring the stable operation and flexible operation of the device in complex environments.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
