Description

Technical field

[0001] The present invention relates to the technical field of lighting devices and in particular relates to a table lamp device with presence detection and adaptive dimming function. Background of the technology

[0002] Table lamps are widely used lighting devices in office, study, and home environments, and are characterized by their ease of use and energy efficiency. However, most table lamps currently rely on manual controls for switching them on and off and adjusting the brightness. They lack the ability to automatically detect occupancy. If the user leaves the room and forgets to turn off the light, it can remain on for an extended period, resulting in wasted energy. Furthermore, the brightness control cannot dynamically adjust to the ambient light and requires repeated manual adjustments, making it cumbersome to use and difficult to precisely fine-tune the lighting for optimal eye comfort. Prolonged use can lead to visual fatigue.Furthermore, the design of many table lamps is structurally fixed, lacking the possibility of height adjustment or extending the detection range for the human body, which makes adaptation to different usage scenarios difficult. Operation is also typically one-sided, failing to meet the diverse and personalized needs of users, thus limiting overall functionality and user experience. Content of the utility model

[0003] The present utility model serves to solve the aforementioned technical problems and offers a table lamp apparatus with presence detection and adaptive dimming function.

[0004] The technical solution of the present utility model is as follows:

[0005] A table lamp apparatus with presence detection and adaptive dimming function, consisting of: a base, a support rod, one end of which is mounted vertically on the base, a housing rotatably connected to the other end of the support rod, a light source module mounted on the housing, and a detection module comprising: a light sensor mounted on the base, a proximity sensor for the human body mounted at the lower end of the housing via a rotating device, and a controller mounted inside the base, wherein the light source module, the light sensor, and the proximity sensor for the human body are electrically connected to the controller.

[0006] Furthermore, a switch is provided at the base, which is electrically connected to the controller.

[0007] Furthermore, a touchscreen is provided at the base, which is electrically connected to the controller.

[0008] Furthermore, the rotating device comprises: a motor, wherein the housing is hollow inside and the motor is firmly mounted in the housing;

[0009] A bracket whose underside is provided with a rotary groove in which the bracket is rotatably mounted and rigidly connected to the motor's output shaft. The proximity sensor for the human body is mounted on the bracket.

[0010] Furthermore, a speech module is installed inside the base, which is electrically connected to the controller.

[0011] Furthermore, the support rod is a telescopic rod consisting of: a first support rod, one end of which is inserted into a groove at the base; a second support rod, which is inserted into the other end of the first support rod and is slidably mounted within it. An adjustable module is located between the first and second support rods, allowing for length adjustment. Advantages of the utility model:

[0012] Through the interaction of the light sensor, the human body proximity sensor, and the controller, the presence of a person can be automatically detected, and the brightness adjusted independently according to the ambient light. When no one is present, the light switches off automatically, effectively reducing unnecessary illumination and improving user comfort. This eliminates the problem of manually operating traditional table lamps. At the same time, the manual switch, touchscreen, and voice module expand the range of possible uses. The rotating mechanism increases the detection range of the human body, and the telescopic arm adapts to different lighting height requirements. The overall structure is simple, the operation convenient, and the versatility highly optimized, thus comprehensively optimizing the user experience and practicality of the table lamp.

[0014] The following provides a clear and complete description of the technical solution of this utility model with reference to the illustrations of the embodiments of this utility model. Obviously, the described embodiments are only a subset of the embodiments of this utility model and not all of them. All other embodiments derived by those skilled in the art without any creative input, based on the embodiments of this utility model, fall within the scope of protection of this utility model.

[0015] As in Fig. As shown in Figures 1 to 3, the table lamp apparatus with presence detection and adaptive dimming function according to an embodiment of the present utility model comprises the base 1, the support rod, the housing 7, the light source module 9 and the detection module.

[0016] One end of the support rod 4 is mounted vertically on the base 1; the housing 7 is rotatably connected to the other end of the support rod 4; the light source module 9 is mounted on the housing 7; the detection module comprises the light sensor 2, the human body proximity sensor 6, and the controller 13, wherein the light sensor 2 is mounted on the base 1; the human body proximity sensor 6 is mounted on the lower end of the housing 7 via a rotation device; the controller 13 is mounted inside the base 1, wherein the light source module 9, the light sensor 2, and the human body proximity sensor 6 are electrically connected to the controller 13.

[0017] In the present utility model, the base 1 provides support and mounting for the entire device. One end of the support rod 4 is mounted vertically to the base 1, while the other end is rotatably connected to the housing 7, thus allowing the angle of the housing 7 (and the light source module 9) to be adjusted to accommodate different lighting requirements. The light source module 9 is mounted on the housing and forms the core of the lighting system. The detection module includes the light sensor and the proximity sensor for the human body. These sensors detect the ambient light and the presence signal of the human body, respectively. The controller is integrated into the base 1 and electrically connected to the light source module 9 and the sensors. It forms the core circuit for signal acquisition and control output. The light source module 9 uses an LED lamp.The controller receives the ambient light signal from the light sensor and the body signal from the proximity sensor and performs an automatic analysis. When someone is present, the brightness of light source module 9 is adjusted based on the ambient light intensity (low ambient light is increased, strong light is dimmed). When no one is present, light source module 9 is switched off to enable presence detection and adaptive dimming, reducing unnecessary lighting and increasing comfort.

[0018] The controller can preferably be an STM32 series microcontroller (e.g., STM32F103) or a 51 series microcontroller (e.g., AT89C52). These controllers are compact, highly integrated, and can be installed inside the base. They are electrically connected to the light source module, light sensor, human body proximity sensor, touchscreen, voice module, and other peripherals via GPIO, I2C, or UART interfaces. They can accurately receive sensor data, analyze commands, and output PWM dimming control signals. They also support cooperative control of multiple modules, taking both functionality and cost-effectiveness into account. These controllers offer mature technology, are easy to implement, and provide high stability.

[0019] In one embodiment of the present utility model, a switch 3 is provided at the base 1, which is electrically connected to the controller 13. By adding a manual switch as a redundant design, the circuit can be directly interrupted / closed, thus adapting to scenarios in which the user must necessarily turn the device on or off, and increasing the flexibility of use.

[0020] In one embodiment of the present utility model, a touchscreen 5 is provided on the base 1, which is electrically connected to the controller 13. The touchscreen 5 offers a visual manual user interface via which the user can actively adjust the brightness, switch between automatic / manual mode, set a delayed shutdown, and add further personalized requirements for the automatic control. This makes operation even more intuitive.

[0021] In one embodiment of the present utility model, the rotating device comprises the motor 8 and the bracket 14. The housing 7 is hollow, and the motor 8 is rigidly mounted within it. A rotary groove 15 is installed at the lower end of the housing 7, in which the bracket 14 is rotatably mounted and rigidly connected to the output shaft of the motor 8. The proximity sensor 6 for the human body is mounted on the bracket 14.

[0022] In one embodiment of the present utility model, the motor 8 drives the bracket 14 to rotate the human body proximity sensor 6, thereby widening the detection angle (to avoid erroneous measurements in one direction). This improves the coverage area and accuracy of human body presence detection and adapts to the detection requirements at different operating positions.

[0023] In one embodiment of the present utility model, a voice module is installed inside the base 1 and electrically connected to the controller 13. The integrated voice module adds a voice control dimension, allowing the user to perform operations such as turning the light on, increasing the brightness, and turning the light off by voice commands without manual intervention. This further enhances user-friendliness.

[0024] It should be noted that the voice module comprises a microphone, a speech processing chip, and a speaker. These three components are integrated into a modular structure and mounted in the designated installation slot within the base. During operation, the microphone collects the user's voice commands in real time, such as turning on the light, increasing the brightness by 50%, turning off the table lamp, or switching to automatic mode. The speech processing chip performs noise reduction, filtering, feature extraction, and command matching (using a built-in predefined voice command library that supports the recognition of basic lighting control commands). The electrical signal generated after matching is transmitted to the controller, which then controls the light source module, the rotating mechanism, and other components to execute the corresponding operations.The speaker provides voice feedback indicating the result of the action, such as "light on" or "brightness adjusted," thus completing an interactive cycle. The voice module is electrically connected to the controller via the I2C or UART communication protocol, with power supplied by the base's integrated power supply module.

[0025] In one embodiment of the present utility model, the support rod consists of a telescopic rod comprising the first support rod 10 and the second support rod 11. A groove is provided at the base 1 into which one end of the first support rod 10 is inserted. The second support rod 11 is slidably installed in the other end of the first support rod 10. An adjustable module 12 for length adjustment is located between the first and second support rods 10 and 11. An external thread is provided at the tip of the first support rod 10; this is a conical external thread whose diameter gradually decreases from bottom to top. The threaded section consists of three to four evenly spaced, arcuate plate bodies extending along the axis of the upper end of the first support rod.The outer surface of the plate bodies is machined with the conical external thread described above, and the plate bodies possess a slight elasticity that allows for radial contraction / expansion. The inner wall of the adjustable module 12 is equipped with a conical internal thread that matches the conical external thread of the first support rod 10. The entire structure forms an annular sleeve, the outer surface of which is provided with non-slip grooves to facilitate manual rotation. For example, when unlocking, the adjustable module 12 can be released by turning it counterclockwise. The module moves upward along the conical external thread of the first support rod 10. As the diameter of the thread decreases from top to bottom, the radial pressure on the arcuate plate bodies of the adjustable module 12 gradually decreases. The arcuate plate bodies return to their natural state (radial expansion).At this moment there is no longer any clamping pressure between the second and the first support rod, so the second support rod can be manually moved along the axis of the first support rod to adjust the length of the support rod and to adjust the desired lighting height.

[0026] The present utility model allows the support rod 4 to be extended and shortened by unlocking / tightening the adjustable module 12, in order to adapt the lighting height to the different needs of the user's size and usage scenarios (such as sitting work or standing reading), thereby increasing the versatility of the device.

[0027] The table lamp device with presence detection and adaptive dimming function, according to one embodiment of the present utility model, can automatically detect the presence of a person through the interaction of a light sensor, a proximity sensor for the human body, and a controller, and independently adjust the brightness based on the ambient light intensity. When no one is present, the lamp switches off automatically, thus reducing unnecessary lighting and increasing comfort. This overcomes the disadvantages of traditional table lamps that require manual operation. At the same time, the operating options are expanded through a manual switch, a touchscreen, and a voice module; the rotation mechanism increases the detection range of the human body; and the telescopic pole adapts to different lighting height requirements.The overall structure is simple, the operation user-friendly, and the versatility high, thus comprehensively optimizing the user experience and practicality of the table lamp.

[0028] The embodiments described above represent only preferred versions of the present utility model and are not intended to limit its scope. Various modifications and adaptations of the present utility model are possible for those skilled in the art. All modifications, equivalent replacements, or improvements made within the spirit and principles of this utility model fall within the scope of protection of the present utility model.
