Description

Technical Field

[0001] This application relates to the field of single-lamp controller technology, and in particular to a highly secure single-lamp controller. Background Technology

[0002] As the name suggests, a lamp controller is a controller that can control each lamp individually. There are many types of lamp controllers, but the main categories are: the first category is technically divided into power line carrier lamp controllers and Zigbee lamp controllers; the second category is functionally divided into lamp controller master units and lamp controller slave units (also known as lamp controller terminals).

[0003] In existing technologies, the setup and on-site installation protection of the main unit of a single lamp controller are particularly important. Some single lamp controllers connect to the slave unit through an antenna transmitter. However, this antenna is sometimes subject to natural environmental factors and intentional damage. In some hot environments or in the event of a fire caused by a short circuit, it may not be able to effectively protect the main chip of the single lamp controller and isolate it from the high temperature. This results in poor safety performance of the single lamp controller. Utility Model Content

[0004] Therefore, it is necessary to provide a highly secure single-lamp controller to address the issue of poor safety performance of traditional single-lamp controllers.

[0005] This application provides a high-safety single-lamp controller, including a PCB base plate, a top cover, a control panel, and a fireproof bottom cover. The PCB base plate, the top cover, and the fireproof bottom cover are installed as a whole. The control panel is installed on the top of the top cover. A control processor is installed on one side of the top of the PCB base plate. An antenna base is fixed to the side of the control processor. An adjustable communication antenna is installed on the top of the antenna base. Expansion connecting strips are installed at the four corners of the bottom of the PCB base plate. The expansion connecting strips are installed and connected to the bottom of the PCB base plate by mounting screws. Four sealing strips are fixed on the four sides of the bottom of the PCB base plate. The sealing strips are arranged in a circular array. The sealing strips are located between the expansion connecting strips and the PCB base plate. A heat insulation plate is installed between the expansion connecting strips on each side. The bottom of the sealing strips and the expansion connecting strips form an opening groove.

[0006] Preferably, the bottom of the PCB base plate is equipped with a connecting threaded post, and the center of the fireproof bottom cover is provided with a base connector. The base connector can be aligned with the connecting threaded post and then installed and connected by threads.

[0007] Preferably, the fireproof bottom cover has four fixed mounting strips on the top of the inner side, the mounting strips are arranged in a circular array, and the mounting strips can be installed and engaged into the slot at the bottom of the sealing strip to achieve the effect of installation and connection.

[0008] Preferably, the top of the PCB base plate is further provided with a power connector, a communication connector and a cooling fan, with the power connector located between the communication connector and the cooling fan.

[0009] Preferably, the power connector is electrically connected to the control processor and the cooling fan via a power connection cable.

[0010] Preferably, the PCB base plate has four upward-facing mounting slots at its top corners.

[0011] Preferably, vertical mounting plates are fixedly provided at the four corners of the bottom of the top cover, and the mounting plates can be installed and inserted into the mounting slots.

[0012] Preferably, a communication connection plate is fixedly provided on the side of the top cover, and the communication connection plate is connected to the communication connector for data connection.

[0014] Preferably, an arc-shaped limiting buckle is installed between the magnetic switch sensors on both sides, and the limiting buckle serves to lock and limit the communication antenna.

[0015] This application relates to a high-security single-lamp controller, which employs a triple-protection structure consisting of an expansion joint made of intumescent fire-resistant material, a sealing strip made of fire-resistant sealing material, and a heat insulation board made of fireproof and heat-insulating layer. Upon exposure to high temperatures, the structure automatically expands and seals, forming a three-dimensional heat insulation barrier that effectively blocks the spread of fire, ensures the safety of the core circuit, complies with fire safety standards, and is suitable for lighting control scenarios in high-temperature or flammable environments. Furthermore, it utilizes a magnetic switch sensor and limit latches to provide both physical and electronic protection. Unauthorized removal of the antenna triggers an audible and visual alarm and forces a power outage, preventing malicious damage or parameter tampering and enhancing the security level of public lighting facilities.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] like Figures 1 to 5 The high-security single-lamp controller shown includes a PCB base plate 101, a top cover 102, a control panel 104, and a fireproof bottom cover 107. The PCB base plate 101, top cover 102, and fireproof bottom cover 107 are assembled as a whole. The control panel 104 is mounted on the top of the top cover 102. A control processor 113 is mounted on one side of the top of the PCB base plate 101. An antenna base 120 is fixed to the side of the control processor 113. An adjustable communication antenna 106 is mounted on the top of the antenna base 120. Expansion connecting strips 124 are installed at the four corners of the bottom of the CB base plate 101. The expansion connecting strips 124 are connected to the bottom mounting screws 125 of the PCB base plate 101. Four sealing strips 114 are fixed on the four sides of the bottom of the PCB base plate 101. The sealing strips 114 are arranged in a circular array. The sealing strips 114 are located between the expansion connecting strips 124 and the PCB base plate 101. A heat insulation plate 122 is installed between the expansion connecting strips 124 on each side. The sealing strips 114 and the bottom of the expansion connecting strips 124 form an opening groove.

[0025] It should be further explained that the heat insulation board 122 is made of fireproof material to form the heat insulation layer, the sealing strip 114 is made of fire-resistant sealing material, and the expansion connecting strip 124 is made of intumescent fireproof material. When the expansion connecting strip 124 is exposed to high temperature, it expands in volume, effectively sealing the four corners of the bottom of the PCB base plate 101, and forming a heat insulation and protection layer on the bottom of the PCB base plate 101 in conjunction with the sealing strip 114 and the heat insulation board 122.

[0026] Furthermore, a connecting threaded post 123 is installed at the bottom of the PCB base plate 101, and a base connector 117 is provided in the center of the fireproof bottom cover 107. The base connector 117 can be aligned with the connecting threaded post 123 and then installed and connected by threads.

[0027] Furthermore, the fireproof bottom cover 107 has four fixed mounting strips 105 on the top of the inner side. The mounting strips 105 are arranged in a circular array and can be installed and engaged into the slot at the bottom of the sealing strip 114 to achieve the effect of installation and connection.

[0028] Furthermore, the top of the PCB base plate 101 is also provided with a power connector 118, a communication connector 116 and a cooling fan 119, with the power connector 118 located between the communication connector 116 and the cooling fan 119.

[0029] Furthermore, the power connector 118 is electrically connected to the control processor 113 and the cooling fan 119 via a power connection cable 121.

[0030] It should be further explained that the signal connection between the control processor 113 and the communication connector 116 is provided by the cooling fan 119, which serves to dissipate heat.

[0031] Furthermore, the PCB base plate 101 has mounting slots 126 with upward openings at the four corners of its top.

[0032] Furthermore, vertical mounting plates 127 are fixedly installed at the four corners of the bottom of the top cover 102, and the mounting plates 127 can be installed and inserted into the mounting slots 126.

[0033] It should be further noted that the mounting plate 127 has a threaded groove, and the top cover 102 can be connected by screws after it is installed on the top of the PCB base plate 101.

[0034] Furthermore, a communication connection plate 103 is fixedly provided on the side of the top cover 102, and the communication connection plate 103 is connected to the communication connector 116 for data connection.

[0035] It should be further explained that the communication connection board 103 has a communication interface for wired connection and the communication antenna 106 for wireless connection.

[0036] Furthermore, an antenna slot 128 with an outward opening is fixedly provided on the side of the top cover 102, and magnetic switch sensors 111 are fixedly provided on the side of the top cover 102 and on both sides of the antenna slot 128.

[0037] Furthermore, an arc-shaped limit buckle 110 is installed between the magnetic switch sensors 111 on both sides, and the limit buckle 110 serves to lock and limit the communication antenna 106.

[0038] It should be further explained that the limit buckle 110 and the magnetic switch sensor 111 form a closed circuit. When the limit buckle 110 is disengaged between the magnetic switch sensors 111 on both sides, an alarm message can be issued through the magnetic switch sensor 111.

[0039] The usage method of this solution is as follows:

[0040] Step 1: Component pre-assembly. The expansion connecting strip 124 at the bottom of the PCB base plate 101 is fixed with the mounting screws 125, and the sealing strip 114 is tightly fitted to the edge.

[0041] Connect the power cord of the lamp to be controlled to the power connector 118 and the signal line to the communication connector 116.

[0042] Step 2: Install the fireproof bottom cover. Align the base connector 117 of the fireproof bottom cover 107 with the connecting threaded post 123, and rotate to lock.

[0043] The mounting clip 105 is inserted into the slot of the sealing strip 114 to form a seal, preventing external high temperature from entering the lamp circuit.

[0044] Step 3: Assemble the top cover and the PCB base plate. Insert the mounting plate 127 of the top cover 102 into the mounting slot 126 and tighten it with screws.

[0045] The control panel 104 is installed on the top of the cover 102 as a local input interface for lighting control commands.

[0046] Step 4: Activate the communication and heat dissipation system, install the communication antenna 106 onto the antenna base 120, and adjust the direction;

[0047] The cooling fan 119 is connected to the power supply via the power connection cable 121 to ensure the cooling of the control processor 113;

[0048] The communication connection board 103 and the communication connector 116 are connected to establish a wired control channel.

[0049] Step 5: Antenna security locking and anti-theft linkage, insert the communication antenna 106 into the antenna slot 128;

[0050] The limit buckle 110 is engaged with the magnetic switch sensor 111;

[0051] If the limit latch 110 is illegally removed, the magnetic switch sensor 111 will trigger an alarm and forcibly cut off the current from the power connector 118 to the lamp.

[0052] Step 6: When the lighting control is executed, control is achieved by inputting commands and inputting switch or dimming commands through the control panel 104;

[0053] When performing remote operation, the wireless signal transmits the instructions to the control processor 113 via the communication antenna 106, or the wired signal transmits the instructions to the control processor 113 via the communication connector 116 through the communication connection board 103, and then executes the subsequent instructions.

[0054] Step 7: When the instruction is executed, the control processor 113 parses the instruction and dynamically adjusts the current output to the lamp through the power connector 118, such as switching on and off and PWM dimming.

[0055] At this time, the communication connector 116 sends feedback on the status of the lighting fixture to the control processor 113.

[0056] Step 8: When performing high temperature protection and emergency control, or when the bottom is exposed to high temperature, the expansion connecting strip 124 expands and seals the four corners, working together with the sealing strip 114 and the heat insulation plate 122 to form a heat insulation layer;

[0057] At this time, the control processor 113 automatically cuts off the power supply to the lamps from the power connector 118 and sends a fault alarm through the communication link.

[0058] Step 9: Adjust the antenna direction, remove the limit clip 110, adjust and then lock it again;

[0059] When resetting the lighting parameters, the brightness curve and timing strategy can be modified through the control panel 104 or the communication interface.

[0060] The technical features of the above embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
