Description

Technical Field

[0001] This utility model relates to the field of smart furniture technology, and in particular to a study desk lighting system and a study desk. Background Technology

[0002] As people's requirements for the quality of learning environments increase, the impact of desk lighting on users' vision protection and concentration is receiving more and more attention. Excessive or insufficient lighting, flickering, or unsuitable color temperature (such as too much blue or cool light) can easily lead to visual fatigue and worsening of myopia.

[0003] In existing technologies, the lighting of study desks mostly uses traditional desk lamps or indoor ceiling lights. Their adjustment relies on the user's subjective judgment, making it difficult to continuously provide a scientific, comfortable, and stable lighting environment. Some study desks are equipped with smart desk lamps, but smart desk lamps mostly use a single sensor (such as a photoresistor) to detect ambient light, which can only sense local brightness and cannot fully reflect the overall light distribution on the desktop (such as the brightness difference between the side closer to the user and the side farther from the user). Moreover, it is difficult to accurately detect color temperature, resulting in a lack of scientific lighting adjustment, poor user visual comfort, and an increased risk of eye fatigue and myopia.

[0004] Therefore, how to adjust the lighting of study desks more scientifically to improve users' visual comfort is a problem that urgently needs to be solved in this field. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

The system embodiments described below are merely illustrative.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0037] like Figure 1 As shown, this utility model embodiment provides a study desk lighting system, which includes a multi-sensor ambient light sensing module 1, a lighting control module 2, and a light source adjustment module 3. The signal output terminal of the multi-sensor ambient light sensing module 1 is connected to the signal input terminal of the lighting control module 2, and the signal output terminal of the lighting control module 2 is connected to the signal input terminal of the light source adjustment module 3.

[0038] The study desk lighting system in this embodiment collects ambient light information such as brightness and color temperature at different locations around the desktop work area through the multi-sensor ambient light sensing module 1. The lighting control module 2 processes this information and generates lighting adjustment commands. The light source adjustment module 3 adjusts the brightness and color temperature of the output light according to the commands so that the ambient light around the study desk meets the preset requirements.

[0039] It should be noted that the data processing algorithm used by the lighting control module 2 in this embodiment to process the ambient light information such as brightness and color temperature at different locations around the desktop working area collected by the multi-sensor ambient light sensing module 1 is not improved, and this utility model does not involve the improvement of computer programs. Specifically, the lighting control module 2 can use existing data fusion algorithms to fuse the ambient light information at different locations around the desktop working area collected by the multi-sensor ambient light sensing module 1. The fusion algorithm can specifically be a weighted average method, a rule-based judgment method, or a combined lighting environment parameter method. The combined lighting environment parameters can include the desktop average illuminance, uniformity, dominant color temperature value, and color temperature difference parameters.

[0040] In this embodiment, the lighting control module 2 uses an STM32 series microcontroller. Specifically, the lighting control module 2 can preset lighting parameter requirements for different scenarios, such as a brightness of 500-700 Lux and a color temperature of 4000-4500K for a reading scenario, and a brightness of 600-800 Lux and a color temperature of 4500-5000K for a writing scenario. The lighting control module 2 compares the received ambient light information with the preset parameters corresponding to the current scenario and generates corresponding lighting adjustment commands. The current scenario can be set by the user through human-computer interaction or automatically identified based on visual recognition technology.

[0041] The desk lighting system in this embodiment can comprehensively and accurately perceive the ambient light around the desk, overcoming the limitation of a single sensor that can only perceive local brightness. It also takes color temperature into account, making the lighting adjustment more scientific and reasonable, providing users with a comfortable and stable lighting environment, and reducing the risk of visual fatigue and myopia progression.

[0042] In one embodiment, the multi-sensor ambient light sensing module 1 includes at least a spatially distributed first light sensor unit 11 and a second light sensor unit 12. The signal output terminals of the first light sensor unit 11 and the second light sensor unit 12 are respectively connected to the signal input terminals of the lighting control module 2.

[0043] The first light sensor unit 11 is disposed on the desktop of the study desk on the side closest to the user;

[0044] The second light sensor unit 12 is located on the side of the desk away from the user.

[0045] In this embodiment, by placing the first light sensor unit 11 and the second light sensor unit 12 on the side closer to the user and the side farther away from the user, respectively, ambient light information near the user and at the far end of the desktop can be collected. This allows for a more comprehensive understanding of the lighting differences in different areas of the desktop, providing a basis for subsequent precise adjustments and avoiding the problem of local over-brightness or under-brightness caused by uneven lighting distribution.

[0046] In one embodiment, both the first light sensor unit 11 and the second light sensor unit 12 include a brightness sensing element 111 and a color temperature sensing element 112.

[0047] In this embodiment, by setting a brightness sensing element 111 and a color temperature sensing element 112 in both the first light sensor unit 11 and the second light sensor unit 12, both the first light sensor unit 11 and the second light sensor unit 12 can detect the brightness information and color temperature information near their respective locations. The combination of the two enables the multi-sensor ambient light perception module 1 to comprehensively collect key parameters of ambient light, providing accurate data support for the lighting control module 2 and ensuring the scientific nature of lighting adjustment.

[0048] Specifically, the brightness sensing element 111 can be one or more of a photoresistor, a photodiode, and an illuminance meter chip, and the color temperature sensing element 112 can be one or more of an RGB color sensor and a spectral sensor chip.

[0049] The brightness sensing element 111 uses photoresistors, photodiodes, illuminance meter chips, etc., which can accurately detect the brightness of ambient light; the color temperature sensing element 112 uses RGB color sensors, spectral sensor chips, etc., which can accurately obtain the color temperature information of ambient light.

[0050] In this embodiment, the brightness sensing element 111 of the first light sensor unit 11 and the second light sensor unit 12 is selected as an ambient light sensor with model number TSL2540 or TSL2541, and the color temperature sensing element 112 is selected as a full-color ambient light sensor with model number VD62818.

[0051] In one embodiment, the multi-sensor ambient light sensing module 1 further includes a third light sensor unit 13, which is disposed above the desktop working area of ​​the study desk, and the signal output terminal of the third light sensor unit 13 is connected to the signal input terminal of the lighting control module 2.

[0052] In this embodiment, the multi-sensor ambient light sensing module 1 sets up a third light sensor unit 13 and places the third light sensor unit 13 above the desktop work area. This allows it to collect overall ambient light information of the work area from an upward perspective, which complements the side information collected by the first and second light sensor units 12. This further improves the comprehensiveness and accuracy of ambient light sensing, enabling the lighting control module 2 to more accurately judge the overall lighting situation.

[0053] In this embodiment, the brightness sensing element 111 of the third light sensor unit 13 can be a BH1750 light intensity sensor, and the color temperature sensing element 112 of the third light sensor unit 13 can be a TCS34303 color temperature sensor. Its spectral response is almost the same as that of the human eye, which can achieve high-precision illuminance and color temperature measurement.

[0054] In one embodiment, the light source adjustment module 3 includes a spatially distributed, adjustable light and color temperature first LED light source 31, a second LED light source 32, and a third LED light source 33. The first LED light source 31, the second LED light source 32, and the third LED light source 33 are respectively connected to the signal output terminal of the lighting control module 2.

[0055] The first LED light source 31 is located on the side of the desk closest to the user.

[0056] The second LED light source 32 is located on the side of the desk away from the user.

[0057] The third LED light source 33 is positioned above the desktop work area of ​​the study desk.

[0058] In this embodiment, a first LED light source 31, a second LED light source 32, and a third LED light source 33 are arranged corresponding to the distribution of the light sensor unit, so that the light source adjustment can specifically compensate for the illumination of different areas of the desktop. When the light in a certain area is insufficient or the color temperature is unsuitable, the LED light source at the corresponding position can be precisely adjusted, thereby ensuring that the illumination of the entire desktop working area is uniform and meets the preset requirements.

[0059] In this embodiment, the first LED light source 31 and the second LED light source 32 both include a warm white LED 311 and a cool white LED 312. The third LED light source 33 also adopts a combination of warm white and cool white. The color temperature is adjusted by adjusting the current ratio of the warm white LED 311 and the cool white LED 312, and the brightness is adjusted by adjusting the total current.

[0060] The light source adjustment module 3, by setting warm white LED 311 and cool white LED 312, can achieve a wider range of color temperature adjustment by adjusting the light emission ratio of the two, which can meet the color temperature needs of different scenarios. For example, when studying, it can be adjusted to a color temperature that makes people focus, and when resting, it can be adjusted to a more comfortable warm tone.

[0061] Specifically, in this embodiment, the light source adjustment module 3 further includes a light source adjustment microcontroller 34, a first PWM dimming circuit 351, a second PWM dimming circuit 352, a third PWM dimming circuit 353, a first transistor switch circuit 361, a second transistor switch circuit 362, and a third transistor switch circuit 363. The signal input terminal of the light source adjustment microcontroller 34 is connected to the signal output terminal of the lighting control module 2. The signal input terminals of the first PWM dimming circuit 351, the second PWM dimming circuit 352, and the third PWM dimming circuit 353 are respectively connected to the signal output terminal of the light source adjustment microcontroller 34. The signal output terminal of the first PWM dimming circuit 351 is connected to the first LED light source 31 through the first transistor switch circuit 361. The signal output terminal of the second PWM dimming circuit 352 is connected to the second LED light source 32 through the second transistor switch circuit 362. The signal output terminal of the third PWM dimming circuit 353 is connected to the third LED light source 33 through the third transistor switch circuit 363. The light source adjustment microcontroller 34 controls the corresponding PWM dimming circuit to output a PWM pulse width modulation signal according to the lighting adjustment command of the light source adjustment module 3, thereby controlling the switching duration of the corresponding transistor switching circuit, and thus controlling the current of the corresponding LED light source to achieve the adjustment of ambient light color temperature and brightness.

[0062] like Figure 2 As shown, in one embodiment, the study desk lighting system further includes a first lamp holder 4, a second lamp holder 5, and a third lamp holder 6. A first light sensor unit 11 and a first LED light source 31 are integrated on the first lamp holder 4, a second light sensor unit 12 and a second LED light source 32 are integrated on the second lamp holder 5, and a lighting control module 2, a third light sensor unit 13, and a third LED light source 33 are integrated on the third lamp holder 6.

[0063] Integrating the light sensor unit and the corresponding LED light source into the lamp holder makes the structure more compact, reduces the complexity of wiring connections, facilitates installation and maintenance, and also makes the overall layout of the study desk more concise and beautiful.

[0064] In one embodiment, the third lamp holder 6 also integrates a control panel 7, which is equipped with brightness adjustment keys, color temperature adjustment keys, scene switching keys, etc. Its signal output terminal is connected to the signal input terminal of the lighting control module 2, and the user can manually control the lighting through the control panel 7.

[0065] The settings in Control Panel 7 allow users to manually input control commands according to their own needs, such as manually adjusting brightness, color temperature, or switching lighting modes, enhancing the interactivity and flexibility of the system and meeting the personalized needs of users.

[0066] In one embodiment, the light source adjustment module 3 further includes a wireless communication interface 37, which is connected to the light source adjustment microcontroller 34. The wireless communication interface 37 is used to communicate with external lighting equipment to control the brightness and color temperature of the external lighting equipment.

[0067] The wireless communication interface 37 enables the system to control external lighting devices, such as ceiling lights in a room, allowing the desk's lighting system to work in conjunction with surrounding lighting equipment to create a more suitable overall lighting environment and expand the range of lighting adjustment. In this embodiment, the wireless communication interface 37 can specifically adopt a Bluetooth module or a Wi-Fi module.

[0068] The working process of the study desk lighting system in the above embodiment is as follows:

[0069] The first light sensor unit 11, the second light sensor unit 12, and the third light sensor unit 13 of the multi-sensor ambient light sensing module 1 collect brightness and color temperature information from different locations on the desktop and transmit the information to the lighting control module 2. The lighting control module 2 analyzes and processes this information, comparing it with preset lighting parameters. If the current ambient light does not meet the preset requirements, it generates a lighting adjustment command and sends it to the light source adjustment module 3. Each LED light source in the light source adjustment module 3 adjusts its brightness and color temperature according to the command, ensuring the ambient light in the desktop work area meets the preset requirements. Users can also manually adjust the lighting or switch between different lighting scenes via the control panel 7. Simultaneously, the lighting control module 2 can control external lighting devices via the wireless communication interface 37 to collaboratively adjust the overall lighting environment.

[0070] This utility model's study desk lighting system can comprehensively sense the ambient light information around the study desk, scientifically adjust the lighting, and provide users with a comfortable study lighting environment. It has high practicality and promotional value.
