Description

Technical Field

[0003] The present invention belongs to the technical field of LED lighting, and specifically relates to an LED intelligent lighting system. Background Art

[0005] Intelligent lighting fixtures can achieve in-depth energy-saving management of the entire life cycle of a digital lighting system, and can also provide services such as comprehensive energy consumption detection, comprehensive carbon emission statistics, optimization of the energy consumption structure, monitoring of pedestrian flow density and direction, monitoring of vehicle flow density and direction, air quality detection, monitoring of road icing conditions, monitoring of road surface water accumulation, wind speed monitoring, real-time ground illuminance monitoring, ambient temperature monitoring, monitoring of the density of four pests, pest monitoring, manhole cover monitoring, and lamp post detection. They can also achieve on-demand lighting, time-sharing lighting, and zonal lighting through intelligent control algorithm rules.

[0006] Under the photoelectric conversion and the use of a large number of intelligent control devices, the heat inside the intelligent lighting fixtures increases sharply. If it cannot be dissipated quickly, the high temperature may damage the electronic components, circuits, and other control components inside the fixtures, shortening the lifespan of the fixtures. At the same time, overheating will also affect the lighting effect.

[0007] Therefore, the present invention provides an LED intelligent lighting system. Summary of the Invention

[0009] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0010] The technical solution adopted by the present invention to solve its technical problems is: An LED intelligent lighting system described in the present invention includes a lamp cover, a PC board, a wind tube, a signal acquisition module control, an air intake assembly, a lighting LED lamp bead and a warning LED lamp bead electrically connected to the PC board;

[0011] The air intake assembly includes an air intake fan and an air intake port. The air intake port is opened on the outer wall of the lamp cover, and the air intake fan is rotatably installed on the inner wall of the wind tube. The rotation of the air intake fan controls the gas to enter the inner cavity of the lamp cover through the air intake port.

[0012] The signal acquisition module includes a sensor and a logic controller. The sensor is fixedly installed on the inner wall of the air duct, and the logic controller is integrated on a PC board. The sensor is electrically connected to the PC board. When the intake fan starts, the air outside the lampshade can be sucked into the inner cavity of the lampshade and discharged into the inside of the air duct. At this time, the smoke sensor set on the inner wall of the air duct can monitor the smoke concentration in the air, convert the detected smoke concentration into a corresponding electrical signal, and send it to the logic controller through the output port. At this time, after the logic controller receives the input signal, it performs logical operations according to the programming rules and finally outputs a control signal to control the lighting LED lamp beads to turn off and the warning LED lamp beads to turn on. At this time, the lampshade will emit red light under the action of the warning LED lamp beads to achieve the warning effect.

[0013] A flow-through pipe is arranged above the PC board. The inner cavity of the flow-through pipe is communicated with the inner cavity of the air duct. The outer wall of the flow-through pipe is provided with lower through holes for gas circulation. When the intake fan sucks the air outside the lampshade into the inner cavity of the lampshade and enters the inner cavity of the flow-through pipe through the air duct, the air can blow on the surface of the PC board through the lower through holes at this time, realizing the heat dissipation of the PC board. There are multiple flow-through pipes, and the heat dissipation effect of the PC board can be effectively improved by arranging multiple flow-through pipes.

[0014] A storage box is arranged above the PC board. The side wall of the storage box is fixedly connected with a mounting plate. The storage box is erected on the top of the PC board through the mounting plate. Through the setting of the mounting plate, there is a certain gap between the bottom end of the storage box and the surface of the PC board.

[0015] A partition plate is fixedly installed on the inner wall of the storage box. The inner cavity of the storage box is divided into an upper chamber and a lower chamber for storing coolant by the partition plate. The upper chamber is communicated with the inner cavity of the air duct.

[0016] The flow-through pipe is set in a U shape. One end of the flow-through pipe extends into the inner cavity of the storage box and penetrates the partition plate, and the other end of the flow-through pipe is located between the storage box and the PC board. A cavity is opened inside the storage box and is distinguished by the partition plate. The lower chamber is a sealed chamber and stores coolant. When the intake fan discharges air into the inner cavity of the flow-through pipe, the coolant set in the lower chamber can cool the air to a certain extent, further improving the effect of cooling the PC board.

[0017] Upper through holes are opened on the outer wall of the flow-through pipe at the end located in the upper chamber. Gas through holes corresponding to the lower through holes are opened on the outer wall of the PC board. The through holes penetrate the PC board, and the central axes of the lower through holes and the through holes coincide. The air flow discharged from the lower through holes can enter the through holes and finally blow on the surfaces of the lighting LED lamp beads and the warning LED lamp beads. The heat generated during the photoelectric conversion of the lighting LED lamp beads and the warning LED lamp beads can be discharged from the exhaust holes opened on the surface of the transparent plate under the action of the wind pressure, further reducing the temperature inside the lampshade.

[0018] The inner wall of the bottom end of the lamp shade is rotatably installed with a transparent plate through internal and external threads. Exhaust holes are formed in the outer wall of the transparent plate, and a plurality of exhaust holes are provided.

[0019] An installation column is fixedly connected to the inner wall of the lamp shade. A connecting bolt is slidably installed on the inner wall of the PC board. The outer wall of the connecting bolt is connected to the inner wall of the installation column through internal and external thread cooperation. By passing the connecting bolt through the PC board and then threadedly connecting it to the installation column, the installation of the PC board can be achieved.

[0020] An installation frame is fixedly installed on the outer wall of the intake fan. The other end of the installation frame is fixedly connected to the inner wall of the air duct. The outer wall of the base of the intake fan is installed on the inner wall of the air duct through a common installation frame.

[0021] A filter screen is fixedly installed on the inner wall of the air inlet.

[0022] The filter screen is made of a deformable material. An elastic rod is fixedly installed on the inner wall of the filter screen. One end of the elastic rod is fixedly installed with a swinging ball. A rotating rod is fixedly installed on the top end of the intake fan, and a striking plate is fixedly installed on the outer wall of the rotating rod.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. For the LED intelligent lighting system of the present invention, by starting the intake fan, the air outside the lamp shade is inhaled into the interior of the lamp shade through the air inlet. Under the action of the air duct, the gas can enter the upper chamber in the accommodation box. At this time, the gas in the inner cavity of the upper chamber enters the flow pipe through the upper through hole formed at the top end of the flow pipe, and is cooled under the action of the coolant in the lower chamber. Finally, it is discharged to the surface of the PC board through the lower through hole formed at the bottom of the flow pipe, and the heat generated on its surface is discharged outside the lamp shade through the exhaust holes formed in the outer wall of the transparent plate, realizing the cooling of the inner cavity of the lamp shade.

[0025] 2. For the LED intelligent lighting system of the present invention, when the intake fan is started, during the process that the gas outside the lamp shade enters the air duct, the gas will come into contact with the smoke sensor arranged inside the air duct, and the smoke in the air is monitored in real time. When the smoke concentration in the air reaches a certain value, the warning LED lamp beads arranged at the bottom of the PC board can be turned on under the action of the logic controller, realizing the warning effect.

Specific embodiments:

[0037] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0038] Embodiment 1: As Figures 1 to 5 shown, an LED intelligent lighting system described in an embodiment of the present invention includes a lamp shade 1, a PC board 9, an air duct 4, a signal acquisition module, an air intake assembly, lighting LED lamp beads and warning LED lamp beads electrically connected to the PC board 9. The top of the lamp shade 1 can be installed on a wall through a common connection structure, and two different colors of light can be displayed through the provided lighting LED lamp beads and warning LED lamp beads.

[0039] The air intake assembly includes an air intake fan 5 and an air inlet 2. The air inlet 2 is opened on the outer wall of the lamp shade 1, and the air inlet 2 is opened above the outer wall of the lamp shade 1. The air intake fan 5 is rotatably installed on the inner wall of the air duct 4. An installation bracket 15 is fixedly installed on the outer wall of the air intake fan 5, and the other end of the installation bracket 15 is fixedly connected to the inner wall of the air duct 4. By rotating the air intake fan 5, the gas is controlled to enter the inner cavity of the lamp shade 1 through the air inlet 2. A drive motor for driving the air intake fan 5 to rotate is provided at the bottom end of the air intake fan 5. The outer wall of the base of the air intake fan 5 is installed on the inner wall of the air duct 4 through a common installation bracket 15. By starting the drive motor, the air intake fan 5 can be driven to rotate, sucking the air outside the lamp shade 1 into the inner cavity of the lamp shade 1 through the air inlet 2 and discharging it into the inner cavity of the air duct 4 at the same time. The model of the drive motor can be selected according to the size of the lamp shade 1 and the needs of those skilled in the art, and no more details will be elaborated here.

[0040] The signal acquisition module includes a sensor 11 and a logic controller. The sensor 11 is fixedly installed on the inner wall of the air duct 4. In this technical solution, it is preferably a smoke sensor, and fire prevention is achieved by monitoring the concentration of smoke in the air.

[0041] The logic controller is integrated on the PC board 9. The sensor 11 is electrically connected to the PC board 9. When the air intake fan 5 is started, the air outside the lamp shade 1 can be sucked into the inner cavity of the lamp shade 1 and discharged into the inside of the air duct 4. At this time, the smoke sensor provided on the inner wall of the air duct 4 can monitor the concentration of smoke in the air. When the detected smoke concentration is converted into a corresponding electrical signal and sent to the logic controller through the output port. At this time, after receiving the input signal, the logic controller performs logical operations according to the programming rules and finally outputs a control signal to control the lighting LED lamp beads to turn off and the warning LED lamp beads to turn on. At this time, the lamp shade 1 will emit red light under the action of the warning LED lamp beads to achieve the warning effect.

[0042] Installation posts 6 are fixedly connected to the inner wall of the lamp shade 1. Connecting bolts 13 are slidably installed on the inner wall of the PC board 9. The outer wall of the connecting bolt 13 is connected to the inner wall of the installation post 6 through internal and external thread cooperation. There are two installation posts 6, and the two installation posts 6 are symmetrically arranged on the inner wall of the lamp shade 1. Installation holes are opened in the inner walls of the two installation posts 6. By passing the connecting bolt 13 through the PC board 9 and then threadedly connecting it to the installation post 6, the installation of the PC board 9 can be realized.

[0043] A transparent plate 7 is rotatably installed on the inner bottom wall of the lamp shade 1 through internal and external threads. Exhaust holes 8 are opened on the outer wall of the transparent plate 7. A plurality of exhaust holes 8 are opened. The transparent plate 7 is made of a visible material. Through the setting of the transparent plate 7, the inside of the lamp shade 1 can be protected, effectively reducing the entry of dust and mosquitoes. The transparent plate 7 can be disassembled from the inner wall of the lamp shade 1 by rotating it, and the operation is simple, and the lighting LED lamp beads or warning LED lamp beads provided on the PC board 9 can be quickly replaced.

[0044] Above the PC board 9, there is a containing box 3. A mounting plate 10 is fixedly connected to the side wall of the containing box 3. The containing box 3 is erected on the top of the PC board 9 through the mounting plate 10. The air duct 4 is arranged on the top of the containing box 3, and there is a gap between the bottom end of the containing box 3 and the surface of the PC board 9.

[0045] A partition plate 12 is fixedly installed on the inner wall of the containing box 3. The inner cavity of the containing box 3 is divided into an upper chamber and a lower chamber for storing coolant by the partition plate 12. The upper chamber is communicated with the inner cavity of the air duct 4. A cavity is opened inside the containing box 3 and is distinguished by the partition plate 12. The lower chamber is a sealed chamber and stores coolant. A circulation pipe is arranged on the side wall of the containing box 3. The circulation pipe extends to the lower chamber, and the other end of the circulation pipe is externally connected to a condenser, and the coolant can be circulated to cool it.

[0046] A circulation pipe 14 is arranged above the PC board 9. The inner cavity of the circulation pipe 14 is communicated with the inner cavity of the air duct 4. When the intake fan 5 sucks the gas outside the lamp cover 1 into the inner cavity of the air duct 4 at this time, the gas can enter the circulation pipe 14 through the air duct 4. The air flow in the inner cavity of the circulation pipe 14 is controlled by the intake fan 5. Lower through holes 17 for gas circulation are opened on the outer wall of the circulation pipe 14. The gas entering the circulation pipe 14 can be discharged through the lower through holes 17 on the outer wall of the circulation pipe 14. The bottom end of the circulation pipe 14 is attached to the PC board 9. When the intake fan 5 sucks the air outside the lamp cover 1 into the inner cavity of the lamp cover 1 and enters the inner cavity of the circulation pipe 14 through the air duct 4, at this time the air can be blown on the surface of the PC board 9 through the lower through holes 17, realizing the heat dissipation of the PC board 9. A plurality of circulation pipes 14 are arranged. By arranging the plurality of circulation pipes 14, the heat dissipation effect of the PC board 9 can be effectively improved.

[0047] The circulation pipe 14 is set in a U shape. One end of the circulation pipe 14 extends into the inner cavity of the containing box 3 and penetrates through the partition plate 12. The other end of the circulation pipe 14 is located between the containing box 3 and the PC board 9. One end of the circulation pipe 14 is almost immersed in the lower chamber, and the top part of the circulation pipe 14 is located in the upper chamber. When the intake fan 5 is started, the air outside the lamp cover 1 can enter the air duct 4 and at the same time enter the inner cavity of the circulation pipe 14 under the action of the intake fan 5. At this time, the coolant stored in the lower chamber can cool the circulation pipe 14 located in the lower chamber. At this time, the gas inhaled from the outside can be cooled at the same time, and finally sprayed on the surface of the PC board 9 through the lower through holes 17 opened at the bottom of the circulation pipe 14. Under the action of the coolant and the circulation pipe 14, the heat dissipation effect of the PC board 9 can be further improved. The gas sprayed on the surface of the PC board 9 can extend downward from both sides of the PC board 9 under the wind pressure of the intake fan 5, and finally be discharged through the exhaust holes 8 opened on the surface of the transparent plate 7.

[0048] An upper through hole 16 is provided on the outer wall of one end of the circulation tube 14 located in the upper chamber, and a through hole 18 corresponding to the lower through hole 17 is provided on the outer wall of the PC board 9. When the air intake fan 5 sucks air into the inner cavity of the wind tube 4, the air can enter the upper chamber opened inside the accommodating box 3. At this time, under the action of the upper through hole 16 opened at the top of the circulation tube 14, the airflow can enter the inner cavity of the circulation tube 14 under the wind pressure of the air intake fan 5. Under the action of the lower chamber containing the coolant, the gas can be cooled and finally discharged from the lower through hole 17. The through hole 18 penetrates the PC board 9, and the central axis of the lower through hole 17 and the through hole 18 coincide. The airflow discharged from the lower through hole 17 can enter the through hole 18 and finally blow on the surface of the lighting LED lamp beads and the warning LED lamp beads. The heat energy generated by the lighting LED lamp beads and the warning LED lamp beads in the photoelectric conversion process can be discharged from the exhaust hole 8 opened on the surface of the transparent plate 7 under the action of the wind pressure, further reducing the temperature of the inner cavity of the lampshade 1.

[0049] Example 2: As Figures 6 to 7 As shown in the comparative example 1, another embodiment of the present invention is that a filter 19 is fixedly installed on the inner wall of the air inlet 2, and when the air inlet fan 5 is started, the air outside the lampshade 1 can be sucked into the interior of the lampshade 1 through the air inlet 2, and the filter 19 can filter impurities in the air.

[0050] The filter 19 is made of a deformable material. An elastic rod 20 is fixedly mounted on the inner wall of the filter 19. A swinging ball 21 is fixedly mounted on one end of the elastic rod 20. A rotating rod 22 is fixedly mounted on the top of the air intake fan 5. A striking plate 23 is fixedly mounted on the outer wall of the rotating rod 22. When the air intake fan 5 rotates, the rotating rod 22 and the striking plate 23 can be driven to rotate synchronously. The swinging ball 21 can be struck by the rotating rod 22 driving the striking plate 23 to rotate. At this time, the swinging ball 21 under force will drive the elastic rod 20 to swing, and under the support of the swinging ball 21, reciprocating shaking can be achieved, and at the same time, the filter 19 can be driven to shake, and the dust on the surface of the filter 19 can be shaken off, thereby improving the filtering effect.

[0051] Working principle: After the lampshade 1 is fixed and installed, the air outside the lampshade 1 is sucked into the lampshade 1 through the air inlet 2 by starting the air intake fan 5. Under the action of the air duct 4, the gas can enter the upper chamber in the containing box 3. At the same time, during the gas circulation process, it will also contact the smoke sensor set inside the air duct 4, and monitor the smoke in the air in real time. At this time, the gas in the inner cavity of the upper chamber enters the circulation tube 14 through the upper through hole 16 opened at the top of the circulation tube 14, and is cooled under the action of the coolant in the lower chamber. Finally, it is discharged to the surface of the PC board 9 through the lower through hole 17 opened at the bottom of the circulation tube 14, and the heat energy generated on its surface is discharged to the outside of the lampshade 1 through the exhaust hole 8 opened on the outer wall of the transparent plate 7.
