Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting control facilities technology, and in particular to a 48V bus communication intelligent lighting controller. Background Technology
[0002] With the global energy crisis and the advancement of the "carbon neutrality" goal, the lighting industry is being prompted to transform towards high efficiency and energy saving. Traditional lighting systems have problems with energy waste. For example, municipal streetlights operate at high brightness continuously in the second half of the night, causing unnecessary energy consumption (annual power consumption of about 43.9 billion kWh, with expenditures of 28.5 billion yuan). 8.48V bus technology, through low-voltage DC power supply and intelligent dimming function, combined with PWM stepless dimming technology (0%-100%), can dynamically adjust the brightness, improving energy efficiency by 20%-50%, which is in line with the concept of "green lighting".
[0003] In existing technologies, traditional 48V bus communication smart lighting controllers are exposed to air and are easily infiltrated by dust. Once dust enters the controller, it forms a conductive film on the circuit board surface. This conductive film can cause current to flow along unexpected paths, leading to short circuits. Short circuits not only cause immediate controller failure but can also damage critical electronic components such as the microprocessor, memory, and communication module, affecting the normal operation of the entire smart lighting system. Dust accumulation also hinders heat dissipation, causing internal temperatures to rise. High temperatures accelerate the aging of electronic components, shorten the controller's lifespan, and increase the risk of system failure. Short circuits and component damage caused by dust intrusion require regular maintenance and replacement of damaged parts, which increases maintenance costs. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a 48V bus communication intelligent lighting controller.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a 48V bus communication intelligent lighting controller, comprising a sealed housing, a control device detachably connected inside the sealed housing, knobs rotatably connected to both ends of the sealed housing, an output rod fixed to the back of the knobs, a support plate fixed to the inner wall of the sealed housing, the support plate rotatably connected to the output rod, a sliding groove provided inside the support plate, an output arm rotatably connected inside the support plate, the output arm fixedly connected to the side end of the output rod, a coupling rotatably connected to the bottom of the output arm, a tail arm rotatably connected to the circumference of the coupling, a connecting rod rotatably connected to the side end of the tail arm, the connecting rod slidingly connected to the inner wall of the sliding groove, Z-arms rotatably connected to both ends of the connecting rod, a limit shaft rotatably connected to the surface of the Z-arms, the limit shaft slidingly connected to the inner wall of the sliding groove, and a transparent cover fixed to the upper end of the Z-arms.
[0006] Preferably, the control device has fins fixed at both ends, a base plate fixed at the bottom of the sealed housing, a fixing pin fixed at the upper end of the base plate, a fixing sleeve fixed on the surface of the fins, fixing teeth fixed inside the fins, a knob threaded onto the inner wall of the fixing sleeve, and a slanted groove at the bottom of the knob. In the prior art, traditional 48V bus communication intelligent lighting controllers use bolts for fixing. Over time, these bolts are prone to corrosion, making disassembly difficult. Bolts exposed to air for extended periods are susceptible to corrosion from environmental factors such as humidity, salt spray, and acidic gases. If the bolt material is of poor quality, such as ordinary carbon steel, corrosion is even more likely. The electrochemical corrosion rate of the V system is faster than that of the conventional 48V system, especially in the case of unsealed connectors, where the corrosion problem is more severe. To address this issue, this invention employs a novel fixing method. After aligning the wing with the fixing pin, the operator presses the control device to the bottom and then rotates the knob, causing it to move downwards along the fixing sleeve. This allows the bottom of the knob to contact the fixing teeth. The operator then continues to rotate the knob, causing it to move further downwards, thus causing the fixing teeth to snap inwards along the inclined groove surface, thereby securing the fixing pin and completing the installation. This avoids the problem of the device being unable to be replaced due to corrosion of the bolt surface preventing rotation.
[0007] Preferably, the retaining pin has threads on its surface, and a truncated cone is fixed to its upper end. The threaded structure provides strong connecting force. When the retaining pin is screwed into the corresponding component, the helical shape of the threads can tightly engage in the threaded hole of the component, forming a tight connection between the retaining pin and the component. This tight connection effectively prevents the retaining pin from loosening or falling off during use, ensuring the stability and reliability of the entire mechanical structure.
[0008] Preferably, the diameter of the arc end of the slide groove is smaller than the diameter of the limiting shaft. The locking effect of the arc end of the slide groove can not only limit the range of motion of the limiting shaft, but also keep the Z-arm stable when it reaches the limit position. The limiting shaft is locked at the arc end of the slide groove, providing a clear and stable termination position for the Z-arm. This helps the mechanical device maintain consistency in cyclic motion or repetitive actions and reduces errors or malfunctions that may occur due to unstable position.
[0009] Preferably, the bottom of the transparent cover is fixed with a reinforcing rib, and the bottom of the reinforcing rib is fixed to the support plate. The fixed connection between the reinforcing rib and the support plate can provide a more stable installation base for the transparent cover, and the transparent cover will not move or loosen relative to the support plate due to vibration or other external forces.
[0010] Preferably, a flexible rubber sleeve is fixed to the periphery of the transparent cover, allowing it to fit tightly against the cover and form a reliable sealing barrier. During operation of the mechanical device, this prevents external impurities such as dust, moisture, and oil from entering the sealed housing, thus protecting the internal precision components from contamination and damage.
[0011] Preferably, the knob surface is multi-faceted and has anti-slip texture. The multi-faceted knob surface can better adapt to the shape of human fingers and gripping methods. When the operator needs to turn the knob, the fingers can naturally fit on the edges, providing a more stable grip point, making the turning operation easier and more accurate.
[0012] Beneficial effects
[0013] 1. In existing technologies, traditional 48V bus communication smart lighting controllers are exposed to the air and are easily infiltrated by dust. Once dust enters the controller, it forms a conductive film on the circuit board surface. This conductive film can cause current to flow along unexpected paths, leading to a short circuit. Short circuits not only cause immediate controller failure but can also damage critical electronic components such as the microprocessor, memory, and communication module, affecting the normal operation of the entire smart lighting system. Furthermore, dust accumulation can hinder heat dissipation from the controller, causing internal temperatures to rise. High-temperature environments accelerate the aging of electronic components, shorten the lifespan of controllers, and increase the risk of system failure. Short circuits and component damage caused by dust intrusion require regular maintenance and replacement of damaged parts, which increases maintenance costs. To address these issues, this invention employs a linkage mechanism. By rotating knobs at both ends, the user drives the internal output rod to rotate, which in turn drives the connected output arm to rotate. The output arm further transmits power to the tail arm via a coupling. Upon receiving power, the tail arm begins to rotate and simultaneously moves within the slide groove via a limiting movement of the linkage. This causes the Z-arm and its surface limiting shaft to slide against the inner wall of the slide groove. Before the limiting shaft reaches the arc groove, the transparent cover moves upward. After the limiting shaft moves upward, the tail arm drives the linkage to move towards the arc groove, causing the Z-arm to rotate. The rotation of the Z-arm is converted into the rotation of the transparent cover, allowing the user to easily access or protect the device inside the sealed housing. This prevents the control device from being exposed to air for extended periods and becoming susceptible to dust intrusion, thus extending the equipment's lifespan.
[0014] 2. In existing technologies, traditional 48V bus communication intelligent lighting controllers are fixed with bolts. Over time, these bolts are prone to corrosion, making disassembly difficult. Bolts, exposed to air for extended periods, are susceptible to corrosion from environmental factors such as humidity, salt spray, and acidic gases. If the bolt material is of poor quality, such as ordinary carbon steel, corrosion is even more likely. The electrochemical corrosion rate of 48V systems is faster than that of conventional 48V systems, especially with non-sealed connectors, where corrosion is more severe. To address this issue, this invention employs a novel fixing method. The operator aligns the wing with the fixing pin, presses the control device to the bottom, and then rotates the knob, causing it to move downwards along the fixing sleeve until the bottom of the knob contacts the fixing teeth. The operator continues to rotate the knob, causing it to move further downwards, thus engaging the fixing teeth along the inclined groove surface, securing the fixing pin and completing the installation. This avoids the problem of the device being unable to be replaced due to bolt surface corrosion preventing rotation. Attached Figure Description

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:
[0024] Reference Figure 1-4 A 48V bus communication intelligent lighting controller includes a sealed housing 1. A control device 102 is detachably connected inside the sealed housing 1. Knobs 2 are rotatably connected to both ends of the sealed housing 1. An output rod 202 is fixed to the back of the knobs 2. A support plate 201 is fixed to the inner wall of the sealed housing 1. The support plate 201 is rotatably connected to the output rod 202. A groove is provided inside the support plate 201. An output arm 203 is rotatably connected inside the support plate 201. The output arm 203 is fixedly connected to the side end of the output rod 202. A coupling 205 is rotatably connected to the bottom of the output arm 203. The coupling 205 has a circumferential surface... A tail arm 204 is rotatably connected, and a connecting rod 206 is rotatably connected to the side end of the tail arm 204. The connecting rod 206 is slidably connected to the inner wall of the slide groove. Z-arms 208 are rotatably connected to both ends of the connecting rod 206. A limiting shaft 207 is rotatably connected to the surface of the Z-arm 208, and the limiting shaft 207 is slidably connected to the inner wall of the slide groove. A transparent cover 101 is fixed to the upper end of the Z-arm 208. In the prior art, traditional 48V bus communication intelligent lighting controllers are exposed to the air and are easily invaded by dust. After dust enters the controller, it will form a conductive film on the surface of the circuit board. This conductive film may cause current to flow in an unexpected path, thereby causing a short circuit. Short circuits not only cause immediate failure of the controller, but may also damage key electronic components, such as microprocessors, memory and communication modules, affecting the normal operation of the entire intelligent lighting system. Dust accumulation will also hinder the heat dissipation of the controller, causing the internal temperature to rise. High-temperature environments accelerate the aging of electronic components, shorten the lifespan of controllers, and increase the risk of system failure. Short circuits and component damage caused by dust intrusion require regular maintenance and replacement of damaged parts, which increases maintenance costs. To address these issues, this invention employs a linkage 206 mechanism. The user rotates the knobs 2 at both ends, driving the internal output rod 202 to rotate. This drives the connected output arm 203 to rotate, which in turn transmits power to the tail arm 204 via a coupling 205. Upon receiving power, the tail arm 204 begins to rotate, simultaneously rotating via the linkage 206. The limiting movement of 06 inside the slide groove causes the Z-arm 208 and its surface limiting shaft 207 to slide against the inner wall of the slide groove. Before the limiting shaft 207 reaches the arc groove, the transparent cover 101 moves upward. After the limiting shaft 207 moves upward, the tail arm 204 drives the connecting rod 206 to move towards the arc groove, causing the Z-arm 208 to rotate. The rotation of the Z-arm 208 is converted into the rotation of the transparent cover 101, thereby allowing the user to easily access or protect the device inside the sealed housing 1, avoiding the problem of dust intrusion due to prolonged exposure of the control device 102 to the air, and extending the service life of the equipment.
[0025] The control device 102 has winglets 3 fixed at both ends, the bottom of the sealed housing 1 has a base plate 301 fixed at the bottom, the upper end of the base plate 301 has a fixing pin 302 fixed at the top, the surface of the winglet 3 has a fixing sleeve 303 fixed at the surface, the inside of the winglet 3 has a fixing tooth 304 fixed at the bottom, the inner wall of the fixing sleeve 303 has a threaded connection to a knob 305, the bottom of the knob 305 has a slanted groove, the surface of the fixing pin 302 has a thread, the upper end of the fixing pin 302 has a cone, the diameter of the arc end of the groove is smaller than the diameter of the limiting shaft 207, the bottom of the transparent cover 101 has a reinforcing rib fixed at the bottom, the bottom of the reinforcing rib is fixed to the support fixing plate 201, the circumference of the transparent cover 101 has a rubber sleeve, the rubber sleeve is a flexible rubber sleeve, the surface of the knob 305 is multi-faceted, and the surface of the knob 305 has anti-slip texture.
[0026] The working principle of this utility model is as follows: By rotating the knobs 2 at both ends, the user drives the internal output rod 202 to rotate, which in turn drives the connected output arm 203 to rotate. The output arm 203 further transmits power to the tail arm 204 through the coupling 205. After receiving the power, the tail arm 204 begins to rotate. At the same time, it moves within the slide groove through the limiting movement of the connecting rod 206. Thus, the Z-arm 208 and its surface limiting shaft 207 slide against the inner wall of the slide groove. Before the limiting shaft 207 reaches the arc groove, the transparent cover 101 moves upward. After the limiting shaft 207 moves upward, the tail arm 204 drives the connecting rod 206 to move towards the arc groove, causing the Z-arm 208 to rotate. The rotation of the Z-arm 208 is converted into the rotation of the transparent cover 101, thereby allowing the user to easily access or protect the device inside the sealed housing 1. This avoids the control device 102 being exposed to the air for a long time and being invaded by dust, thus extending the service life of the equipment.
