Description

Technical Field

[0001] The invention relates to the technical field of staircase electric lighting, in particular to an energy-saving device for controlling lighting by utilizing an induction sensor. Background Art

[0002] With the acceleration of urbanization and people's emphasis on energy conservation and environmental protection, the intelligentization and energy saving of lighting systems have become a hot topic of research. In public buildings and residential buildings, stairwell lighting systems have particular energy-saving potential, because these areas usually do not need lighting when no one is around, but need to provide sufficient brightness to ensure safety and comfort when someone passes by.

[0003] In the prior art, most stairwell lighting systems use traditional switch control methods, such as manual pull-wire switches or timer switches. These methods have many shortcomings. First, manual pull-wire switches require pedestrians to actively operate, which is not only inconvenient, but also may cause inconvenience or negligence in dim light or emergency situations, affecting the lighting effect and safety. Secondly, although the timer switch can be automated to a certain extent, it cannot be flexibly adjusted according to the actual light conditions and pedestrian activities in the stairwell, which often leads to energy waste or insufficient lighting. In addition, traditional stairwell lighting systems usually use fixed-position lamps and cannot be dynamically adjusted according to the position and distance of pedestrians. This may not only lead to insufficient lighting in the area where pedestrians are located, affecting walking safety, but also may cause discomfort and energy waste due to excessive lighting. Especially when there are pedestrians passing through the stairwell at the same time, the fixed-position lamps often cannot meet the lighting needs of multiple people passing through, reducing the user experience. In addition, the inspection and maintenance of traditional lighting systems are also relatively difficult. Lamps are usually fixed on the ceiling or wall. When maintenance personnel need to inspect or replace lamps, they often need to use tools such as ladders or scaffolding, which is not only cumbersome to operate, but also poses certain safety risks.

[0004] Therefore, based on the above search and in combination with the prior art, an energy-saving device for controlling lighting using an induction sensor is proposed to solve the above problem. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0032] In a typical implementation of this application, please refer to Figures 1 to 12 As shown, an energy-saving device for controlling lighting using an induction sensor comprises: a mounting base 1, a lampshade 2 is arranged on the bottom surface of the mounting base 1, a convex lens 3 is arranged inside the lampshade 2 through an adjusting component, a collar 4 is sleeved on the outer surface of the convex lens 3, a mounting groove 5 is opened on the bottom surface of the mounting base 1, a plurality of LED lamps 6 are arranged inside the mounting groove 5, a driver 7 is fixedly installed in the mounting groove 5, and a circuit board 8 is arranged on one side of the driver 7.

[0033] As a preferred implementation in this embodiment, please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the adjustment component includes: two cylinders 9, the two cylinders 9 are fixedly mounted at the two ends of the lampshade 2 respectively, the adjacent surfaces of the two cylinders 9 are rotatably connected with disks 10, a connecting plate 11 is fixedly mounted between the two disks 10, and a movable groove 12 is provided on the top surface of the connecting plate 11. The adjustment component also includes a movable part and a rotating part.

[0034] As a preferred implementation in this embodiment, please refer to Figure 2 , Figure 5 and Figure 6As shown, the moving parts include: two moving blocks 13, the two moving blocks 13 are respectively slidably installed in the moving groove 12, the moving groove 12 is made of transparent material to reduce the impact on the light emitted by the LED lamp 6, the top and bottom surfaces of the two moving blocks 13 are fixedly installed with limit blocks 14, the limit blocks 14 are made of iron material, and the top surface of the connecting plate 11 is provided with a plurality of electromagnets 15, the electromagnets 15 can cooperate with the limit blocks 14, when the electromagnets 15 are energized in turn, the limit blocks 14 will be driven to move, and the surfaces of the two limit blocks 14 facing the ring 4 are fixedly installed with electric push rods 16, and the output ends of the two electric push rods 16 are respectively connected to the top surfaces on both sides of the ring 4.

[0035] As a preferred implementation in this embodiment, please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the rotating part includes: a drive motor 17, which is arranged in one of the cylinders 9, a circular groove 18 is opened on the side wall of one of the cylinders 9, and the drive motor 17 is fixedly installed in the circular groove 18, and the output shaft of the drive motor 17 is connected to the side wall of one of the disks 10.

[0036] Through the above features, the convex lens 3 and the collar 4 can be adjusted. Specifically, when there are pedestrians in the stairwell, the convex lens 3 and the collar 4 will be adjusted according to the trajectory of the pedestrians. If lateral adjustment is required, one side of the electromagnet 15 on the connecting plate 11 is energized to move the limit block 14. When the limit block 14 moves, the moving block 13 moves in the moving groove 12. At the same time, the driving motor 17 in the circular groove 18 will start to drive the disc 10 to rotate. When the disc 10 rotates, the moving groove 12 will also rotate synchronously. Because the electric push rod 16 is connected to the limit block 14, the convex lens 3 and the collar 4 can move and rotate while the limit block 14 moves and the moving groove 12 rotates. The convex lens 3 is made to face the direction of the pedestrian. When the pedestrian is getting closer, the output shaft of the electric push rod 16 is extended in sequence, so that the convex lens 3 is farther away from the LED lamp 6, so that the focusing effect of the light after passing through the convex lens 3 is reduced, and the excessive brightness is avoided, which causes discomfort to the pedestrian's eyes. When the pedestrian is getting farther and farther, the output shaft of the electric push rod 16 will be retracted in sequence, so that the convex lens 3 is gradually close to the LED lamp 6, so that the focusing effect of the light after passing through the convex lens 3 is enhanced, so that the LED lamp 6 has a farther range of illumination at the same brightness. If there are pedestrians going up and down the stairwell at the same time, the convex lens 3 is in the initial position shown in the figure and is not adjusted, and the current of the LED lamp 6 will be increased to make the LED lamp 6 brighter;

[0037] It is worth mentioning that the two limit blocks 14 will limit the moving block 13 to prevent the moving block 13 from escaping from the moving slot 12 when the driving motor 17 rotates the moving slot 12, and the electromagnet 15 is energized in turn to move the limit block 14. This is an existing mature technical means, so it will not be described in detail in the present invention.

[0038] As a preferred implementation in this embodiment, please refer to Figure 3 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, a human motion sensor 19 is fixedly installed in the mounting groove 5. The human motion sensor 19 can detect the movement of pedestrians, thereby triggering the lighting of the stairwell lights. A light intensity sensor 20 is fixedly installed on one side of the human motion sensor 19. The light intensity sensor 20 is used to detect the intensity of ambient light. When the natural light or ambient light in the stairwell is insufficient, the light intensity sensor 20 will send a signal to make the human motion sensor 19 and the sound sensor 21 work. When a pedestrian is detected passing by, the LED light 6 works to ensure sufficient lighting. On the contrary, if there is sufficient light in the stairwell, the sensor will send a signal to stop the human motion sensor 19 and the sound sensor 21 from working, and turn off the LED light 6 to achieve the purpose of energy saving. A sound sensor 21 is arranged on the other side of the human motion sensor 19. When the sound sensor 21 detects a sound at a specific decibel level, the sound sensor 21 can trigger the lighting of the LED light 6 to provide lighting for pedestrians.

[0039] Through the above features, the human motion sensor 19, the light intensity sensor 20 and the sound sensor 21 cooperate with each other to control the adjustment component and the LED lamp 6. Specifically, when the natural light or the surrounding light in the stairwell is insufficient, the light intensity sensor 20 will send a signal to make the human motion sensor 19 and the sound sensor 21 work, and the LED lamp 6 will not start at this time. When a pedestrian passes by, the light intensity sensor 20 turns on the LED lamp 6, and the human motion sensor 19 and the sound sensor 21 cooperate with each other to detect the distance of the pedestrian, and transmit the detected data to the electromagnet 15, the electric push rod 16 and the drive motor 17, so that they cooperate with each other to adjust the convex lens 3. When a pedestrian passes by, the light sensor 20 will control the LED light 6, the human motion sensor 19 and the sound sensor 21 to turn off. Before turning off, the electromagnet 15, the electric push rod 16 and the drive motor 17 will cooperate with each other to make the convex lens 3 in the initial position. The initial position is shown in the figure. If the human motion sensor 19 and the sound sensor 21 detect that there are pedestrians going up and down the stairs at the same time, the convex lens 3 will remain in the initial position at this time, and the light sensor 20 will control the brightness of the LED light 6 to make the LED light 6 at the brightest to facilitate the pedestrian to pass. When the pedestrian passes, the light sensor 20 will control the LED light 6, the human motion sensor 19 and the sound sensor 21 to turn off;

[0040] It is worth mentioning that the working mechanism of the light intensity sensor 20 is:

[0041] Light detection: The light sensor 20 continuously monitors the natural light or ambient light intensity in the stairwell. This is usually achieved through a light-sensitive element, such as a photoresistor or a photodiode, whose resistance value or current output changes with changes in light intensity;

[0042] Signal sending: When it is detected that the light intensity is lower than a preset threshold, that is, when the stairwell is dark, the light intensity sensor 20 will send an electrical signal to the control system (that is, the microprocessor on the circuit board 8).

[0043] Activation of the human body movement sensor 19 and the sound sensor 21:

[0044] Receiving signal: After the control system receives the signal sent by the light intensity sensor 20, it activates the human movement sensor 19 and the sound sensor 21, which means that the sensors start working and are ready to detect the presence and activities of pedestrians;

[0045] Sensor working mode: The human motion sensor 19 can use infrared technology or microwave radar to detect the movement of pedestrians, and the sound sensor 21 captures sounds at a specific decibel level through a microphone.

[0046] Startup of LED light 6:

[0047] Pedestrian detection: Once the human motion sensor 19 or the sound sensor 21 detects the presence of a pedestrian (either through movement or sound), they send a signal to the control system;

[0048] LED light 6 starts: after receiving these signals, the control system will instruct the driver 7 to start the LED light 6, and the LED light 6 will then light up to provide lighting for the stairwell.

[0049] The cooperation between the human body movement sensor 19 and the sound sensor 21:

[0050] Data collection: Human motion sensors 19 and sound sensors 21 not only detect the presence of pedestrians, but also collect information about the location and movement of pedestrians. This includes the direction of movement, speed, and relative distance from the sensor;

[0051] Data transmission: The collected data is transmitted to the control modules of the electromagnet 15 , the electric push rod 16 and the drive motor 17 through the circuit on the circuit board 8 .

[0052] Adjustment of convex lens 3:

[0053] Analyze data: The control module analyzes the data received from the sensor to determine the location and distance of the pedestrian;

[0054] Adjustment instructions: Based on these data, the control module sends instructions to the electromagnet 15, the electric push rod 16 and the drive motor 17. The electromagnet 15 cooperates with the limit block 14 to adjust the movement of the convex lens 3. The electric push rod 16 is used to change the distance between the convex lens 3 and the LED light 6. The drive motor 17 is used to rotate the convex lens 3 to adjust the direction of the light beam;

[0055] Dynamic adjustment: As pedestrians move, these components work together to dynamically adjust the position and angle of the convex lens 3 to ensure that the light is always focused on the area where the pedestrians are located while avoiding discomfort caused by excessive lighting.

[0056] The light sensor 20 controls the brightness of the LED lamp 6:

[0057] Brightness adjustment requirements: When the human motion sensor 19 and the sound sensor 21 detect multiple pedestrians (such as pedestrians going up and down the stairs at the same time), or when the lighting needs to be improved to meet the needs of a specific scene, the light intensity sensor 20 may need to adjust the brightness of the LED lamp 6;

[0058] Signal transmission and response: The light intensity sensor 20 (or control system) sends a brightness adjustment signal to the driver 7 according to the current light conditions and pedestrian detection;

[0059] Brightness adjustment: The driver 7 adjusts the current supplied to the LED lamp 6 according to the received signal, thereby changing its brightness. When maximum illumination is required (such as when there are many pedestrians), the driver 7 will increase the current to make the LED lamp 6 reach the brightest state.

[0060] The inner wall of the mounting groove 5 is provided with an internal thread, and the outer wall of the lampshade 2 is provided with an external thread. The lampshade 2 is installed under the mounting seat 1 through the cooperation of the internal thread and the external thread. The above features facilitate maintenance personnel to inspect the equipment.

[0061] As a preferred implementation in this embodiment, please refer to Figures 1 to 12 As shown, a touch switch is arranged on the wall of the stairwell, and the touch switch is electrically connected to the LED lamp 6, the driver 7, the circuit board 8, the electromagnet 15, the electric push rod 16, the drive motor 17, the human body movement sensor 19, the light intensity sensor 20 and the sound sensor 21.

[0062] As a preferred implementation in this embodiment, please refer to Figures 1 to 12 As shown, the LED lamp 6, the driver 7, the circuit board 8, the electromagnet 15, the electric push rod 16, the driving motor 17, the human movement sensor 19, the light intensity sensor 20 and the sound sensor 21 are connected to the power system of the building through wires.

[0063] Working principle:

[0064] When in use, the device of the present invention installed in the stairwell first continuously monitors the natural light or ambient light intensity in the stairwell through the light intensity sensor 20. When it is detected that the light intensity is lower than the preset threshold, that is, when the light in the stairwell is insufficient, the light intensity sensor 20 sends an electrical signal to the microprocessor on the circuit board 8. After receiving the signal, the control system activates the human motion sensor 19 and the sound sensor 21, so that they start working to prepare to detect the presence and activities of pedestrians. When a pedestrian passes through the stairwell, the human motion sensor 19 detects the movement of the pedestrian using infrared technology or microwave radar and sends a signal to the control system. At the same time, the sound sensor 21 may also capture sounds of a specific decibel level and also send a signal. After receiving these signals, the control system instructs the driver 7 to start the LED lamp 6 to provide lighting for the stairwell. At the same time, the human motion sensor 19 and the sound sensor 21 not only detect the presence of pedestrians, but also collect information about the position and movement of pedestrians, such as the direction of movement, speed and relative distance from the sensor, and transmits this information to the control module of the electromagnet 15, the electric push rod 16 and the drive motor 17 through the circuit on the circuit board 8. The control module analyzes the data received from the sensor, determines the position and distance of the pedestrian, and sends the corresponding adjustment instructions. The electromagnet 15 cooperates with the limit block 14 to adjust the movement of the convex lens 3; the electric push rod 16 changes the distance between the convex lens 3 and the LED light 6 according to the instruction to adjust the focusing effect of the light; the drive motor 17 is used to rotate the convex lens 3 to adjust the direction of the light beam. As the pedestrian moves, these components work together to dynamically adjust the position and angle of the convex lens 3 to ensure that the light is always focused on the area where the pedestrian is located, while avoiding the discomfort caused by excessive lighting. Specifically, if there are pedestrians walking in the stairwell, the convex lens 3 and the collar 4 will be adjusted according to the trajectory of the person's movement. When lateral adjustment is required, one side of the electromagnet 15 on the connecting plate 11 is energized to attract the limit block 14 to move, thereby driving the moving block 13 to slide in the moving groove 12. At the same time, the drive motor 17 in the circular groove 18 is started, driving the disc 10 to rotate, thereby causing the connecting plate 11 and the moving groove 12 to rotate synchronously. Since the electric push rod 16 is connected to the limit block 14, the convex lens 3 and the collar 4 move and rotate while the limit block 14 moves and the moving groove 12 rotates, so that the convex lens 3 faces the direction of the pedestrian. When the pedestrian is getting closer, the output shaft of the electric push rod 16 extends out in sequence, so that the convex lens 3 is farther away from the LED lamp 6, reducing the focusing effect of the light after passing through the convex lens 3, and avoiding discomfort to the pedestrian's eyes caused by excessive illumination. On the contrary, when the pedestrian is getting farther and farther away, the output shaft of the electric push rod 16 is retracted in sequence, so that the convex lens 3 gradually approaches the LED lamp 6, enhancing the focusing effect of the light after passing through the convex lens 3, so that the LED lamp 6 has a farther illumination range at the same brightness.If the human motion sensor 19 and the sound sensor 21 detect pedestrians going up and down the stairs at the same time, the convex lens 3 maintains the initial position unchanged, and the light intensity sensor 20 controls the LED lamp 6 to reach the brightest state to facilitate the passage of pedestrians. When the pedestrian passes, the light intensity sensor 20 will control the LED lamp 6, the human motion sensor 19 and the sound sensor 21 to turn off, and before turning off, the electromagnet 15, the electric push rod 16 and the drive motor 17 cooperate with each other to reset the convex lens 3 to the initial position. In addition, the mounting groove 5 and the lampshade 2 are installed by the mutual cooperation of the internal thread and the external thread, which is convenient for maintenance personnel to inspect and repair the equipment. A touch switch is provided on the wall of the stairwell, which is electrically connected to each electrical component in the device of the present invention and is used to manually control the switch state of the device. The entire device is connected to the power system of the building through wires to ensure stable operation.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
