[0002] A desk lamp is a type of lamp. This appliance is mainly placed on a desk or dining table for lighting.

The effect is limited to the area around the desk lamp, which is convenient for reading, learning, and saving energy. The desk lamp has far exceeded the value of the desk lamp itself and has become a rare work of art.

[0003] The Chinese invention patent with publication number CN114688483A and publication date July 1, 2022, relates to an adaptive desk lamp, comprising a lamp pole, a rotating motor, a lamp head, a light source module, a processor, a distance sensor, and a light sensor; the rotating motor is configured to drive the rotation of the lamp head; the light sensor is arranged at the lower end of the lamp pole and detects light environment information and sends it to the processor; the processor calculates the dimming information of the light source module and / or the rotation direction and amplitude of the rotating motor according to the received light environment information, and controls the light source module and the rotating motor to adjust; although the invention expands the dynamic adjustment range of the desk lamp through the adaptive desk lamp, it still has the following defects: In actual use, desk lamps are widely used in the learning environment of teenagers as an important tool for learning.

Secondly, since each teenager has different sitting habits, existing desk lamps lack the function of automatically adjusting their shape (such as height, angle, etc.) according to personal usage.

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0029] Application scenarios: In actual use, desk lamps are important tools for learning and are widely used in the learning environment of teenagers. However, existing desk lamps have some shortcomings when used. First, existing desk lamps usually cannot automatically sense the current brightness in the room and adjust their own lighting brightness according to the ambient light, which may cause the light to be too strong or too weak, affecting the visual comfort and eye health of teenagers. Secondly, since each teenager has different sitting habits, existing desk lamps lack the function of automatically adjusting their shape (such as height, angle, etc.) according to personal usage. Inappropriate desk lamp position may affect the lighting effect, resulting in limited vision or shadows, which in turn affects learning efficiency and vision health.

[0030] like Figures 1 to 9 An adaptive lighting intensity intelligent LED desk lamp shown in the figure comprises a lamp holder 1, a rotating seat 2 is fixedly mounted on the top of the lamp holder 1, an adjustable bracket 3 is fixedly mounted on the top of the rotating seat 2, a lamp holder holder 4 is fixedly connected to the end of the adjustable bracket 3, a lamp shade 5 is rotatably connected to the lamp holder holder 4, a monitoring component is arranged inside the lamp shade 5 for continuously monitoring the temperature inside the lamp shade 5, an LED lighting wick 6 is fixedly mounted inside the lamp shade 5, and a shading plate 7 is fixedly mounted on the top of the lamp shade 5; A heat dissipation substrate 8 is fixedly installed inside the lampshade 5. The heat dissipation substrate 8 is located above the LED lighting lamp core 6. A plurality of heat dissipation devices are arranged in a linear array on the heat dissipation substrate 8 to dissipate the heat generated by the LED lighting lamp core 6. Two connecting plates 9 are fixedly installed inside the lampshade 5, an annular heat exchange tube 10 is fixedly installed between the two connecting plates 9, a placement plate 11 is fixedly installed on the outer wall of the annular heat exchange tube 10, liquid is contained inside the annular heat exchange tube 10, and the annular heat exchange tube 10 is located above the heat dissipation substrate 8, and two groups of airflow blowing components are arranged on the annular heat exchange tube 10; The lamp holder 1 is provided with a voice recognition module 12 for accurately recognizing user voice commands; The lamp holder 1 is provided with a lighting adaptive adjustment module and a sitting posture adjustment module. The lighting adaptive adjustment module is used to adaptively adjust the lighting brightness of the LED lighting core 6 according to the current light brightness. The sitting posture adjustment module is used to obtain the current user's sitting posture to control the adjustable bracket 3 to automatically adjust the shape of the desk lamp.

[0031] It should be noted that, in view of the increasing demand for lighting convenience and intelligence in modern times, the disadvantages of traditional desk lamps are prominent. The smart LED desk lamp is based on a single-chip microcomputer and uses a high-precision voice recognition module 12 to accurately recognize user voice commands, such as turning on and off lights, dimming and color adjustment, etc. The specific work is as follows: after the microcontroller parses the instruction, it goes through complex circuit design and signal conversion, and uses the driving circuit to control the state of the LED light group. At the same time, during the use of teenagers, the light adaptation module includes an ambient light sensor, which can detect the brightness of the room in real time, and automatically adjust the lighting brightness and shape according to the actual situation, which is conducive to ensuring that the light is always in the best state, which is conducive to reducing eye fatigue, energy saving and comfort, and can protect the vision health of teenagers; and during the user's use, the sitting posture adjustment module can monitor the user's sitting posture in real time through an integrated camera or sensor, and automatically adjust its shape as needed to provide the most suitable lighting angle and range to monitor the user's sitting posture in real time; Furthermore, in this design, the hardware MCU selection, interface design, power management, software voice algorithm optimization, and control logic construction have all been repeatedly tested and debugged. By promoting the integration of voice and lighting, it is beneficial to improve the user's lighting experience; In summary, the lighting adaptive module can automatically sense the ambient light and detect the indoor brightness in real time through the ambient light sensor, automatically adjust the lighting brightness, and ensure that the light is always in the best state. In addition, the smart LED desk lamp also has a personalized shape adjustment function to adapt to different sitting postures. Through a flexible adjustable structure and intelligent sensing technology, it automatically adjusts the height, angle and other parameters according to the sitting posture of teenagers to ensure the best lighting effect. This intelligent design can not only protect the eyesight of teenagers, but also improve their learning efficiency, provide a personalized user experience, and enhance overall comfort and satisfaction.

[0032] Furthermore, the above are existing mature technologies and will not be elaborated in detail here.

[0033] It should be understood that during use, the user selects to control the smart LED desk lamp through the voice recognition module 12. As the smart LED desk lamp is used for a long time, the LED lighting wick 6 will generate a certain amount of heat and accumulate inside the lampshade 5. At this time, the generated heat is first absorbed by the heat dissipation substrate 8. At the same time, the heat dissipation device provided will continue to effectively dissipate the heat, thereby facilitating rapid heat dissipation and maintaining the optimal operating temperature of the LED lighting wick 6. In addition, during the continuous heat dissipation of the heat dissipation device, the annular heat exchange tube 10 will also assist in absorbing the heat of the LED lighting wick 6, thereby facilitating rapid heat dissipation. At the same time, the monitoring component set inside the lampshade 5 will continuously monitor the temperature inside the lampshade 5, which is conducive to detecting the above-mentioned heat dissipation effect. If the monitoring component detects that the temperature exceeds the predetermined temperature value, on the one hand, it means that the current heat generated is abnormal, and the user needs to be notified to check the heat dissipation device to determine whether there is a hidden danger. On the other hand, in order to prevent the heat from being unable to dissipate, thereby causing damage to the LED lighting wick 6 and other electronic components, an airflow blowing component needs to intervene and deal with it. The airflow blowing component blows air to the heat dissipation device. On the first hand, the heat is taken out from the heat dissipation holes provided on the lampshade 5 by applying airflow. On the second hand, the airflow acts on the heat dissipation device and the annular heat exchange tube 10, thereby assisting in rapid cooling. On the third hand, the dust accumulated inside the lampshade 5 is blown away by the applied airflow, which is conducive to reducing the situation where dust accumulation affects heat dissipation and the life of electronic components. In addition, the airflow blowing component can also cooperate with the heat dissipation device. Through the cooperation between the two, the airflow can better clean the places that are difficult to clean, which helps to improve the cleaning effect and prevent dust accumulation from damaging the circuit.

[0034] As a further embodiment of the present invention, the heat dissipation device includes a connecting plate 13, which is fixedly connected to the heat dissipation substrate 8. Two groups of connecting frames 14 are symmetrically arranged on the side wall of the connecting plate 13. The number of each group of connecting frames 14 is multiple, and a heat dissipation fin plate 15 is rotatably connected between each two symmetrical connecting frames 14.

[0035] As a further embodiment of the present invention, the airflow blowing component includes a sliding seat 16, which is slidably connected to the outer wall of the annular heat exchange tube 10, and a wind storage box 17 is slidably connected to the side wall of the sliding seat 16. The bottom of the wind storage box 17 is provided with an inclined surface 18, and the inclined surface 18 is provided with a blowing groove 39. An air pump 19 is fixedly installed on the top of the wind storage box 17, and the air inlet end of the air pump 19 is fixedly connected to the wind storage box 17 through a connecting pipe 20. A driving component is provided at the bottom of the sliding seat 16 for driving the wind storage box 17 to reciprocate, and a first spring 21 is sleeved between the placement plate 11 and the sliding seat 16. The first spring 21 is sleeved on the outer wall of the annular heat exchange tube 10, and a pulling and rolling component is provided between the sliding seat 16 and the placement plate 11 for pulling the sliding seat 16 to move.

[0036] It should be understood that during the operation of the smart LED desk lamp, heat will be generated at the light source of the LED lighting wick 6. The heat dissipation substrate 8 first absorbs the heat, and then conducts the heat to the heat dissipation fins 15. The heat dissipation fins 15 further absorb and dissipate the heat, which is conducive to achieving efficient heat management. When the monitoring component obtains that the temperature value exceeds the threshold or it is manually determined that the air pump 19 needs to be turned on, the air pump 19 will be started by controlling the air pump 19 to blow air into the air storage box 17. The blowing slot 39 guides the air flow to the heat dissipation fins 15, which is conducive to accelerating the heat dissipation through forced convection. While blowing, the driving component is synchronously started to push the air storage box 17 to move along the side wall of the sliding seat 16. This movement is conducive to ensuring that the air flow can cover all the heat dissipation fins 15, achieve all-round heat dissipation, and significantly improve the heat dissipation efficiency; and, as the air storage box 17 moves, the air flow not only helps to dissipate heat, but also effectively removes dust between the two heat dissipation fins 15, which not only improves the heat dissipation efficiency, but also reduces dust accumulation and prolongs the service life of the equipment; and, because dust may accumulate on the contact surface between the heat dissipation fin 15 and the heat dissipation substrate 8, affecting the heat dissipation effect, the heat dissipation fin 15 is designed to be able to rotate at a certain angle. degree, so that under the action of the airflow, the heat dissipation fins 15 can be deflected. When the heat dissipation fins 15 are deflected, on the one hand, they will temporarily break away from the close contact with the heat dissipation substrate 8, providing more paths for the airflow to enter between the contact surfaces. When the air storage box 17 passes through and blows the airflow, the deflection of the heat dissipation fins 15 will allow the airflow to more easily enter the gap between the heat dissipation fins 15 and the heat dissipation substrate 8. This airflow can help to effectively blow away the dust in these areas, thereby helping to reduce the situation of cleaning dead corners. On the other hand, when the heat dissipation fins 15 can rotate, they can be deflected under the action of the airflow to change the path of the airflow. This dynamic adjustment allows the airflow to be more evenly distributed throughout the heat dissipation device, which is helpful to avoid local overheating. In addition, due to the rotation of the heat dissipation fins 15, the uncertainty of the airflow at the heat dissipation fins 15 is increased, which helps to evenly dissipate heat for different parts. With the movement of the air storage box 17 and the continuous action of the airflow, the heat dissipation fins 15 are constantly deflected and reset, which helps to ensure that all contact surfaces can be fully cleaned. Furthermore, after the air storage box 17 moves to the specified position, the winding assembly drives the sliding seat 16 to move, so that the sliding seat 16 moves toward the next heat dissipating fin 15, and then repeats the above steps to process the heat dissipating fin 15 in all directions. After the winding assembly stops moving, it will quickly reset under the action of the first spring 21, which is conducive to subsequent processing.

[0037] It should be further explained that the rotation of the heat dissipation fin plate 15 by a specified angle means that after the heat dissipation fin plate 15 rotates, it can automatically return to its original position under the action of gravity, thereby facilitating subsequent heat dissipation.

[0038] As a further implementation scheme of the present invention, the bottom of the air storage box 17 is slidably connected to a baffle 22, and a push rod 23 is fixedly connected to the side wall of the baffle 22. The bottom of the air storage box 17 is fixedly connected to a socket 24, and one end of the push rod 23 away from the baffle 22 is slidably connected to the socket 24. A second spring 25 is fixedly connected between the baffle 22 and the socket 24, and the second spring 25 is sleeved on the outer wall of the push rod 23. A pressure detection component is provided at the bottom of the air storage box 17 for monitoring the pressure.

[0039] It should be understood that in order to prevent the heat dissipation fins 15 and the heat dissipation substrate 8 from getting stuck due to various reasons such as dust accumulation or adhesion, the airflow cannot blow the heat dissipation fins 15, making it difficult to clean the dust on the contact surface; when the airflow cannot blow the heat dissipation fins 15, the pulling component will start, driving the sliding seat 16 to move, and then pushing the air storage box 17 to approach the heat dissipation fins 15. The baffle 22 approaches the heat dissipation fins 15 driven by the sliding seat 16 and tries to push it to deflect. This direct contact pushing method is conducive to ensuring that the airflow can act on the contact surface between the heat dissipation fins 15 and the heat dissipation substrate 8 to effectively remove dust. In this process, various situations may occur. The first situation is that after the baffle 22 applies a thrust, it directly pushes the heat dissipation fins 15 to deflect. After the heat dissipation fins 15 are deflected, the baffle 22 passes smoothly. At this time, the airflow can directly act on the contact surface between the heat dissipation fins 15 and the heat dissipation substrate 8 to effectively blow away the dust. The second situation is that if the baffle 22 fails to push after applying a thrust The heat dissipation fins 15 are deflected. In order to avoid damage to the heat dissipation fins 15, the baffle 22 will compress the second spring 25 to make way, which is beneficial to prevent the heat dissipation fins 15 from being too tightly adhered to the heat dissipation substrate 8 and causing damage to the heat dissipation fins 15. At this time, the pressure detection component will intervene in the monitoring. If the pressure exceeds the preset value, if the pressure detected by the pressure detection component exceeds the preset value, it is judged that the heat dissipation fins 15 are too tightly adhered to the heat dissipation substrate 8, and it is difficult to push the heat dissipation fins 15 to deflect. At this time, an early warning is given to relevant personnel to indicate that further maintenance or processing is required. The third situation is that after the baffle 22 contacts the heat dissipation fins 15, the second spring 25 is first compressed to make way, and then the second spring 25 always applies an elastic thrust to the baffle 22, and the elastic thrust continues to act on the heat dissipation fins 15, which helps the baffle 22 to pass through the heat dissipation fins 15. Even if the initial thrust is not enough to push the heat dissipation fins 15, the elastic thrust can gradually help the heat dissipation fins 15 to deflect, which is beneficial to avoid jamming.

[0040] It should be noted that the baffle 22 is made of rubber.

[0041] As a further embodiment of the present invention, the pressure detection assembly includes a pressure plate 26 , which is fixedly mounted on the bottom of the air storage box 17 , and a pressure sensor 27 is fixedly mounted on one side of the pressure plate 26 close to the heat dissipation fin plate 15 .

[0042] It should be understood that when the baffle 22 contacts the heat dissipating fin 15 and compresses the second spring 25 to make way, if the baffle 22 moves a certain distance and contacts the pressure sensor 27, the pressure sensor 27 will capture the pressure information and compare it with the pre-set threshold. If the threshold is exceeded, an alarm needs to be issued to the relevant personnel.

[0043] As a further embodiment of the present invention, two top rods 28 are symmetrically fixedly connected to the side wall of the sliding seat 16 , and the ends of the two top rods 28 are fixedly connected to a shielding plate 40 , which is located near the edge of the side wall of the sliding seat 16 .

[0044] It should be understood that in the above example, it is explained that the heat dissipation fin plate 15 is pushed to deflect by directly contacting and pushing the baffle plate 22. However, in order to prevent the baffle plate 22 from causing damage to the heat dissipation fin plate 15 when it contacts the heat dissipation fin plate 15, a shielding plate 40 is provided. Before the baffle plate 22 contacts the heat dissipation fin plate 15, when the air storage box 17 moves to the edge of the sliding seat 16, the shielding plate 40 partially blocks the blowing slot 39. By partially blocking the blowing slot 39, the airflow is concentrated and passes through a smaller opening, thereby enhancing the wind force. The enhanced wind force can push the heat dissipation fin plate 15 to deflect, avoiding the baffle plate 22 from directly contacting the heat dissipation fin plate 15, which is beneficial to reducing potential mechanical The risk of damage is that if the increased wind force still cannot push the heat sink 15 to deflect, the baffle 22 will move closer to the heat sink 15. In this case, the baffle 22 will directly contact and apply thrust to the heat sink 15. By first using the increased wind force to try to push the heat sink 15, the possibility of the baffle 22 directly contacting the heat sink 15 is reduced, and the risk of mechanical damage is reduced. The increased wind force can more effectively remove dust between the heat sink 15 and the heat sink substrate 8, and maintain the efficient operation of the device. If the increased wind force cannot push the heat sink 15, the baffle 22 will intervene, and it is equipped with a pressure detection component to ensure that the heat sink 15 will not be excessively damaged.

[0045] As a further embodiment of the present invention, a plurality of dust-sticking strips 29 are fixedly mounted on the bottom of the air storage box 17 . The dust-proof grooves 30 are formed on the dust-sticking strips 29 . The dust-sticking strips 29 are located on a side of the baffle 22 close to the heat dissipation fins 15 .

[0046] It should be understood that during the movement of the air storage box 17, when the air storage box 17 moves, the sticky dust belt 29 will contact the heat dissipation fin 15 and adhere to the dust remaining on its surface. The sticky dust belt 29 can also assist in adhering to the dust blown by the airflow to prevent the dust from falling back onto the heat dissipation fin 15 or other components again, thereby keeping the device tidy. When the enhanced wind force cannot push the heat dissipation fin 15 to deflect, the baffle 22 will apply a thrust under the action of the compression spring to deflect the heat dissipation fin 15. In order to prevent the baffle 22 from colliding with the slide groove on the air storage box 17 when releasing the spring force, the sticky dust belt 29 can absorb the impact force caused by the release of the spring, reduce the direct collision between the baffle 22 and the air storage box 17, and thus prevent mechanical damage.

[0047] As a further embodiment of the present invention, the monitoring component includes a plurality of temperature sensors, and all the temperature sensors are distributed inside the lampshade 5 .

[0048] Specifically, the heat generated inside the lampshade 5 is monitored by a temperature sensor to determine whether to start the air pump 19 for intervention according to actual conditions.

[0049] As a further implementation scheme of the present invention, the drive assembly includes a mounting cover 31, which is fixedly mounted on the bottom of the sliding seat 16, and a first motor 32 is fixedly mounted inside the mounting cover 31. A threaded rod 33 is fixedly connected to the output shaft end of the first motor 32, and a threaded seat 34 is threadedly connected to the outer wall of the threaded rod 33, and the threaded seat 34 is fixedly connected to the side wall of the air storage box 17.

[0050] It should be understood that by controlling the first motor 32 to start, the first motor 32 drives the threaded rod 33 to rotate, the threaded rod 33 drives the threaded seat 34 to move, and the threaded seat 34 drives the air storage box 17 to slide along the side wall of the sliding seat 16.

[0051] As a further implementation scheme of the present invention, the winding assembly includes a second motor 35 and a pulling seat 36. The second motor 35 is fixedly connected to the top of the receiving seat 24. The output shaft end of the second motor 35 is fixedly connected to a winding wheel 37. A winding rope 38 is wound around the winding wheel 37. The pulling seat 36 is fixedly connected to the top of the sliding seat 16. The winding rope 38 is fixedly connected to the pulling seat 36.

[0052] It should be understood that by controlling the second motor 35 to start, the second motor 35 drives the winding wheel 37 to rotate, and the rotating wheel winds up the winding rope 38, which is conducive to pulling the sliding seat 16 to move through the pulling seat 36.

[0053] Working principle of the present invention: During use, the user selects to control the smart LED desk lamp through the voice recognition module 12. As the smart LED desk lamp is used for a long time, the LED lighting wick 6 will generate a certain amount of heat and accumulate inside the lampshade 5. At this time, the generated heat is first absorbed by the heat dissipation substrate 8. At the same time, the heat dissipation device will continue to effectively dissipate the heat, which is conducive to ensuring rapid heat dissipation and maintaining the optimal working temperature of the LED lighting wick 6. In addition, during the continuous heat dissipation of the heat dissipation device, the annular heat exchange tube 10 will also assist in absorbing the heat of the LED lighting wick 6, which is conducive to rapid heat dissipation. At the same time, the monitoring component set inside the lampshade 5 will continuously monitor the temperature inside the lampshade 5, which is conducive to detecting the above-mentioned heat dissipation effect. If the monitoring component detects that the temperature exceeds the predetermined temperature value, on the one hand, it means that the current heat generated is abnormal, and the user needs to be notified to check the heat dissipation device to determine whether there is a hidden danger. On the other hand, in order to prevent the heat from being unable to dissipate, thereby causing damage to the LED lighting wick 6 and other electronic components, an airflow blowing component needs to intervene and deal with it. The airflow blowing component blows air to the heat dissipation device. On the first hand, the heat is taken out from the heat dissipation holes provided on the lampshade 5 by applying airflow. On the second hand, the airflow acts on the heat dissipation device and the annular heat exchange tube 10, thereby assisting in rapid cooling. On the third hand, the dust accumulated inside the lampshade 5 is blown away by the applied airflow, which is conducive to reducing the situation where dust accumulation affects heat dissipation and the life of electronic components. In addition, the airflow blowing component can also cooperate with the heat dissipation device. Through the cooperation between the two, the airflow can better clean the places that are difficult to clean, which helps to improve the cleaning effect and prevent dust accumulation from damaging the circuit.
