Description

Technical Field

[0001] This application relates to the field of smart desk lamp technology, and more particularly to a smart desk lamp based on millimeter-wave radar. Background Technology

[0002] A smart desk lamp is a modern lighting device that integrates sensing technology and automatic control functions. Compared with traditional manual control lamps, it can sense the environment or human body status through sensors and automatically realize operations such as turning the lamp on and off and adjusting the brightness. It is widely used in home studies, office workstations and other scenarios.

[0003] A search revealed a Chinese patent for an intelligent desk lamp (authorization announcement number CN208222161U), comprising: a base with a touch switch on its upper surface and a controller electrically connected to the touch switch inside the base; a lamp post with its lower end connected to the middle of the upper surface of the base; and a lamp body with its lower end connected to the upper end of the lamp post, an infrared detection device on the middle of the upper surface of the lamp body, several upper lamp tubes on the upper surface of the lamp body, and several lower lamp tubes on the lower surface of the lamp body. The infrared detection device, the lower lamp tubes, the touch switch, and the controller constitute a first control loop, while the upper lamp tubes, the touch switch, and the controller constitute a second control loop. Although the patented technology has a simple structure, it allows for dual-use lighting: the upper lamp tubes are used for indoor lighting, and the lower lamp tubes are used for office reading lighting. The multiple control options enable the desk lamp to be intelligent.

[0004] However, the aforementioned devices still have some drawbacks in actual use. The most obvious one is that the desk lamp uses an infrared sensor to detect human movement and automatically turns on the lamp when the movement of a person is detected. However, on the one hand, the infrared sensor is easily affected by the external environment. When exposed to direct sunlight, hot air from an air conditioner vent, or other heat sources, it often fails to detect movement, causing the desk lamp to "not light up when it should" or "turn on and off accidentally," seriously affecting its reliability. On the other hand, existing smart desk lamps generally adopt a one-piece molded structure with a high degree of integration between the lamp body and the lamp tube. Once a single lamp tube is damaged, it cannot be replaced individually, and the entire desk lamp must be replaced, which increases the user's cost and causes unnecessary waste of resources. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main purpose of this application is to provide a smart desk lamp based on millimeter-wave radar.

[0006] The technical solution of this application is as follows: A smart desk lamp based on millimeter-wave radar includes a base, a lamp post fixedly connected to the top of the base, a snap-fit ​​connector fixedly connected to the end of the lamp post away from the base, a snap-fit ​​component inside the snap-fit ​​connector, a square component inserted between the snap-fit ​​connector and the snap-fit ​​component, a locking bolt connected to the internal thread of the square component, the square component and the snap-fit ​​component connected by the locking bolt, a lampshade fixedly connected to the side of the snap-fit ​​component away from the lamp post, and a lighting lamp fixedly installed at the bottom of the lampshade.

[0007] In a preferred embodiment, a cover is fitted onto the top of the base, and a control component is provided on the outer side of the cover. The control component includes a controller fixedly installed on the inner wall of the base, a timer fixedly installed on the outer side of the cover, and a millimeter-wave radar sensor fixedly installed on the outer wall of the cover and below the timer.

[0008] In a preferred embodiment, the snap-fit ​​connector is provided with a limiting component inside, the limiting component including a square slot formed inside the snap-fit ​​component and the snap-fit ​​connector.

[0009] In a preferred embodiment, three snap-fit ​​holes are provided on both sides of the snap-fit ​​connector, and snap-fit ​​pins are snapped into the interior of each snap-fit ​​hole.

[0010] In a preferred embodiment, protective plates are provided on both sides of the snap-fit ​​connector, and the snap-fit ​​posts are fixedly connected to the corresponding protective plates.

[0011] In a preferred embodiment, the square slot engages with the outer wall of the square component, and a battery is installed inside the base.

[0012] In a preferred embodiment, a touch switch is fixedly installed on the top of the housing, and the battery, lighting lamp, timer, millimeter-wave radar sensor and touch switch are all electrically connected to the controller.

[0013] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0014] In this application, when the light at the bottom of the lampshade is damaged, it is not necessary to replace the entire lamp. Only by unscrewing the locking bolt and separating the square piece from the snap-fit ​​piece, the lampshade can be disassembled and the light replaced separately. Furthermore, the protective plates on both sides of the snap-fit ​​piece can play an important protective role in the locking bolt, reducing the corrosion of the locking bolt by external moisture and ensuring the normal use of the lamp.

[0015] In this application, by setting up a millimeter-wave radar sensor, it is possible to capture subtle movements of a static human body, such as turning pages of a book or breathing. The signal is then transmitted to the controller, which quickly processes the signal and triggers the lighting to turn on and off, ensuring the stable operation of the "lights on when people are present, lights off when people leave" function. This significantly improves reliability in various usage scenarios. Furthermore, the equipped timer is linked to the controller and can record the user's usage time in real time. When the controller detects that the user has been continuously lighting the lights for more than a preset time, it can trigger the lights to flicker slightly or reduce their brightness to remind the user to rest, thus providing a health assistance function. Moreover, the millimeter-wave radar sensor is not affected by changes in light intensity or ambient temperature, and can accurately detect dynamic human bodies to adapt to the lighting needs of various environments such as studies and offices.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1-4A smart desk lamp based on millimeter-wave radar includes a base 1. A lamp post 4 is fixedly connected to the top of the base 1. A snap-fit ​​connector 13 is fixedly connected to the end of the lamp post 4 away from the base 1. A snap-fit ​​component 10 is provided inside the snap-fit ​​connector 13. A square component 17 is inserted between the snap-fit ​​connector 13 and the snap-fit ​​component 10. A locking bolt 16 is threaded inside the square component 17. The square component 17 and the snap-fit ​​component 10 are connected by the locking bolt 16. A lampshade 5 is fixedly connected to the side of the snap-fit ​​component 10 away from the lamp post 4. A light 6 is fixedly installed at the bottom of the lampshade 5. When the light 6 at the bottom of the lampshade 5 is damaged, the entire desk lamp does not need to be replaced. Only the locking bolt 16 needs to be unscrewed to separate the square component 17 from the snap-fit ​​component 10, and the lampshade 5 can be disassembled separately to replace the light 6. The protective plates 11 on both sides of the snap-fit ​​connector 13 can play an important protective role in the locking bolt 16 to reduce the corrosion of the locking bolt 16 by external moisture, so as to ensure the normal use of the desk lamp.

[0023] Specifically, a cover 3 is fitted onto the top of the base 1. A control component is located on the outside of the cover 3. The control component includes a controller 2 fixedly installed on the inner wall of the base 1, and a timer 7 fixedly installed on the outside of the cover 3. Through the setting of the millimeter-wave radar sensor 8, it can capture the slight movements of a static human body, such as turning pages of a book or breathing. The signal is then transmitted to the controller 2, which quickly processes the signal and triggers the lighting 6 to turn on and off, ensuring the stable operation of the "lights on when people are present, lights off when people leave" function. This significantly improves the reliability in usage scenarios. The timer 7 is linked with the controller 2 and can record the user's usage time in real time. When continuous use is detected, the timer will automatically turn on and off. If the lighting continues beyond the preset time, the controller 2 can trigger the light 6 to flicker slightly or reduce its brightness to remind the user to rest, which also has a health assistance function. The millimeter-wave radar sensor 8 is not affected by the intensity of light or changes in ambient temperature, and can accurately detect dynamic human bodies to adapt to the lighting needs of various environments such as study rooms and offices. The millimeter-wave radar sensor 8 is fixedly installed on the outer wall of the housing 3 and below the timer 7. The inside of the snap-fit ​​connector 13 is provided with a limiting component, which includes a square snap-fit ​​groove 14 opened inside the snap-fit ​​piece 10 and the snap-fit ​​connector 13. Three snap-fit ​​holes 12 are opened on both sides of the snap-fit ​​connector 13, and snap-fit ​​posts 15 are snapped into the inside of each snap-fit ​​hole 12.

[0024] Specifically, protective plates 11 are provided on both sides of the snap-fit ​​connector 13, and snap-fit ​​posts 15 are fixedly connected to the corresponding protective plates 11. The square snap-fit ​​slot 14 engages with the outer wall of the square piece 17. A storage battery is installed inside the base 1, and a touch switch 9 is fixedly installed on the top of the cover 3. The storage battery, lighting lamp 6, timer 7, millimeter-wave radar sensor 8, and touch switch 9 are all electrically connected to the controller 2. Through the settings of the controller 2, the storage battery, lighting lamp 6, timer 7, millimeter-wave radar sensor 8, and touch switch 9 can be controlled to start and stop.

[0025] Working principle: The millimeter-wave radar sensor 8 (model: S3KM111) can capture subtle movements of a static human body, such as turning pages or breathing. The signal is then transmitted to the controller 2, which quickly processes the signal and triggers the lighting 6 to turn on and off, ensuring the stable operation of the "light on when someone is present, light off when someone leaves" function. The timer 7 is linked with the controller 2 and can record the user's usage time in real time. When the controller 2 detects that the user has been using the light continuously for more than a preset time, it can trigger the lighting 6 to flicker slightly or reduce its brightness to remind the user to rest, thus providing a health assistance function. When the lighting 6 at the bottom of the lampshade 5 is damaged, the entire lamp does not need to be replaced. Only the locking bolt 16 needs to be unscrewed, and the square piece 17 and the snap-fit ​​piece 10 need to be separated to disassemble the lampshade 5 and replace the lighting 6. The protective plates 11 on both sides of the snap-fit ​​piece 13 provide important protection for the locking bolt 16, reducing the corrosion caused by external moisture and ensuring the normal use of the lamp.
