[0023] Traditional desks generally lack integrated lighting systems. When users need lighting or to create an ambiance, they often need to purchase separate lighting devices such as desk lamps and light strips. This not only leads to messy wiring and complicated installation, but also to inconsistent power supply and fragmented control, affecting ease of use and the tidiness of the space. To improve this situation, some desks have begun to be equipped with integrated lighting systems, using integrated light strips and other structures to enhance the visual effect of the scene. Gaming desks, in particular, have the most urgent need for lighting systems. However, even some desks that are currently equipped with lighting systems still suffer from poor user interaction with the lighting system.

[0024] To address the above problems, this application provides a method for controlling table lighting. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The table lighting control method provided in the embodiments of this application will now be described. In the embodiments of this application, the table includes multiple light-emitting units, and the installation position of the light-emitting units can be flexibly configured according to the table type and usage scenario. Common installation methods include: LED strips can be installed around the edge of the tabletop and the outer sides of the legs; LED strips can be installed along the length of the legs; LED strips can be embedded in the front edge of the tabletop to illuminate the work surface, and LED strips can be installed on the underside beam to create a floor atmosphere; LED strips can be installed in the central functional area of ​​the tabletop and the side frame, providing localized lighting, and vertical LED strips can be installed on the side frame to enhance the three-dimensional visual effect; LED strips can be installed on the bottom of the tabletop and the sides of the lifting column of a height-adjustable desk to avoid shadows on the desktop, and LED strips can be installed on the sides of the lifting column to respond to the lifting action; LED strips can be installed on the edge of the keyboard area and the monitor bracket beam of a gaming desk, with LED strips on the keyboard edge adapting to the operating angle, and LED strips on the monitor bracket beam supplementally illuminating the area around the screen; LED strips can be installed below the reading and writing area and on the inner sides of the legs of a study desk, with LED strips below the reading and writing area providing uniform lighting to protect eyesight, and LED strips on the inner sides of the legs avoiding direct light interference from the floor. In other words... Figure 1 and Figure 2 The table shown is a height-adjustable table, which includes a tabletop 1 and height-adjustable table legs 2. Multiple light-emitting units include a desktop light strip 3 installed on the tabletop 1 and a table leg light strip 4 installed on the height-adjustable table legs 2.

[0025] like Figure 3 As shown, in some embodiments of this application, the table lighting control method includes: S100. Acquire trigger signals. Trigger signals represent table body actions or interactive events associated with the table. Trigger signals are various signals that reflect the table's status or user operations. Table body action signals include the raising and lowering of height-adjustable tables, the unfolding and folding of folding tables, the flipping of the tabletop of flip-top tables, and the adjustment of table leg angles; interactive event signals include user pressing the lighting control button on the table's hand controller, sending a light effect switching command via a mobile APP, continuous keystrokes on a keyboard connected to the table, mouse clicks, external human body sensors detecting user proximity to the table, and the table's load-bearing sensor detecting the placement of heavy objects.

[0026] In some embodiments, the table control system can acquire trigger signals through built-in or external detection components. Built-in components may include height sensors, angle sensors, distance sensors, and load-bearing sensors, which can be used to collect control signals for the table's rise and fall, table tilting or leg adjustment, user proximity, and item placement, respectively. External components may include hand controllers, wireless communication modules, and peripheral interfaces, which can be used to receive user pressing commands, APP or Bluetooth device commands, and trigger signals from peripherals such as keyboards and mice. These components can convert the control signals for table movement and other physical actions and operation commands into electrical signals and transmit them to the control system.

[0027] The table control system can receive or send table movement control signals through built-in or external control components. These control signals can be directly used as lighting trigger signals, and lighting control signals can be sent simultaneously with the table movement control signals. Built-in control components may include a lifting control module, a folding control module, and a flipping control module, which can respectively generate control signals for raising and lowering the table, unfolding and retracting the folding table, and flipping the tabletop of the flipping table. These control signals, while driving the table's mechanical movements, can be simultaneously transmitted to the lighting control system as trigger signals. External control components may include a hand controller, a wireless communication module, and an APP control interface, which can respectively receive user-input table movement commands and generate corresponding control signals. These control signals, while being sent to the table drive system, can be simultaneously transmitted to the light strip controller as lighting trigger signals. In addition, the system can also acquire other types of trigger signals through components such as distance sensors and load sensors. These signals, along with the table movement control signals, can independently or collaboratively trigger lighting changes.

[0028] S200. Based on the trigger signal, determine the corresponding lighting change mode. The control system can pre-store the correspondence between different trigger signals and lighting effect parameters. Lighting effect parameters can include lighting effect type, color parameters, brightness curve, and change cycle. Lighting effect types can cover flowing, gradient, flashing, constant light, breathing, etc.; color parameters can include monochrome, RGB gradient, color temperature adjustment, etc.; brightness curves can include uniform on / off, linear gradient, step change, etc.; the change cycle can be fixed or dynamically adjusted according to the intensity of the trigger signal. For example, a table rising signal can correspond to a mode combining bottom-to-top flowing light and RGB gradient, a reading scene interaction command can correspond to a combination of warm light constant light and specific color temperature and brightness, and a user approach signal can correspond to a combination of slow breathing light and warm white light.

[0029] The control system internally stores a database mapping trigger signals to lighting change modes. Upon receiving a table movement control signal and a synchronized lighting trigger signal, the system can quickly determine the corresponding lighting effect parameter combination through data comparison. If it is a user-defined interactive event, the control system can determine the lighting change mode based on the user-preset parameter combination. Because the table movement control signal and the lighting trigger signal are issued synchronously, mode matching can be initiated without waiting for the actual table movement to complete, significantly reducing response time.

[0030] S300 controls multiple light-emitting units to perform synchronized lighting effects according to the lighting change pattern. This means that two light-emitting units can work according to the same timing and consistent lighting effect parameters, avoiding misalignment or rhythm differences in lighting effects. For example, the light strips on the edge of the tabletop and the outer side of the table legs can simultaneously activate upward flowing lighting effects, the lights on the desktop reading and writing area and the inner side of the table legs can simultaneously switch to warm, constant light, and the light strips on the lifting column and the bottom of the tabletop can synchronously complete the brightness gradient.

[0031] The control system can output control signals to the two light-emitting units via a dual-channel synchronous drive module. These control signals can include timing synchronization commands and light effect parameter commands, ensuring that the two light-emitting units can initiate light effect changes and adjust color and brightness at the same rhythm as the table's movement begins. For example, when a lowering control signal is sent to the table, the light strips on the leading edge of the tabletop and the crossbeam under the table can be synchronously controlled to complete a gradual downward retraction light effect at the same rate; when a folding control signal is sent, the light strips at the connection between the movable edge of the tabletop and the folding bracket can be synchronously driven to perform a synchronized dimming light effect, achieving real-time linkage between table movement and light changes.

[0032] The lighting control method of this embodiment can significantly improve the interaction real-time performance and coordination of the tableware. The traditional tableware lighting system needs to wait for the table body action to occur before detecting the signal, resulting in a response delay. However, through the design of synchronously emitting the table body action control signal and the lighting trigger signal in this method, the lighting change and the table body action can be started synchronously. Users can intuitively feel the immediate linkage between the table body control and the lighting feedback. For example, when the lifting control signal is issued, the lighting synchronously flows, and when the folding instruction is issued, the lighting synchronously dims, enhancing the sense of technology and immersion of the tableware, and is especially suitable for scenarios with high requirements for interaction timeliness such as e-sports and office work.

[0033] The synchronous light effect design of multiple light-emitting units, combined with the control signal synchronous trigger mechanism, can achieve the precise correspondence between the lighting and the table body action, forming a three-dimensional and coordinated visual atmosphere. It avoids the visual limitation brought by a single light-emitting unit or the sense of disconnection where the light effect and the action are out of sync. For example, the synchronous flowing light effect at the edge of the tabletop and the table legs can enhance the dynamic visual experience of the table body lifting, and the synchronous warm light in the reading and writing area of the tabletop and the area under the table can improve the uniformity of lighting, which not only enhances the beauty of the tableware but also improves the use comfort.

[0034] The table body action control signal and the lighting trigger signal are synchronously emitted, enabling the linkage between the lighting and the table body action without the user having to operate an additional lighting control key. For example, when the user issues a lifting instruction through the hand controller, there is no need to manually adjust the lighting anymore, and the system can automatically trigger the corresponding light effect synchronously, reducing the operation steps and enhancing the use convenience. At the same time, the synchronous light effect design can avoid the trouble of the user manually adjusting multiple light-emitting units and lower the use threshold.

[0035] In some embodiments of this application, the multiple light-emitting units include at least two light strips; the lighting change mode includes a dynamic light effect that changes along the length direction of the light strip; controlling at least two light-emitting units to execute a synchronous light effect includes: controlling at least two light strips to synchronously execute a dynamic light effect along the length direction.

[0036] The multiple light-emitting units can adopt the configuration form of at least two light strips. The light strips have the advantages of flexible installation, uniform light emission, and adaptability to various table body structures, and can be flexibly arranged and installed according to the functional requirements of the tableware. Common installation combinations include the edge of the tabletop and the outer side of the lifting table legs. A strip-shaped light strip can be installed around the edge of the tabletop, and a light strip can be installed along the length direction on the outer side of the lifting table legs, and the light strips on the left and right table legs can adopt a parallel structure; alternatively, the front edge of the tabletop and the support cross beam under the table can be selected. A light strip can be embedded inward at the front edge of the tabletop to illuminate the operation area, and a light strip can be installed on the cross beam under the table to create an atmosphere; it can also be configured as the functional area of the tabletop and the side frame of the table. A light strip is installed below the functional area of the tabletop to provide local lighting, and a light strip is installed vertically on the side frame of the table to enhance the three-dimensional visual effect.

[0037] The lighting effects can include dynamic lighting effects that change along the length of the light strip. These effects can encompass various types, such as flowing light effects, gradient light effects, flashing light effects, and breathing light effects, and can intuitively respond to table movements or user interactions. Multiple light strips simultaneously executing dynamic lighting effects along their length primarily refers to having the same light effect cycle. When light strips of different lengths execute this type of dynamic lighting effect, the rate can be flexibly adjusted according to the length difference and does not need to be consistent. However, the light effect cycle of all light strips must be unified to ensure that the light effects start and end simultaneously. For example, in a flowing light effect, a longer light strip can use a faster light movement rate, and a shorter light strip can use a slower light movement rate, but both must complete a full flowing cycle within the same cycle; in a gradient light effect, the brightness or color transition rates of long and short light strips can differ, but the gradient must start and end simultaneously.

[0038] Controlling at least two light-emitting units to execute synchronized lighting effects involves controlling at least two light strips to execute dynamic lighting effects with a unified cycle and adapted speed along their length. This means that the dynamic lighting effects of different light strips have completely consistent start and end times, forming a unified lighting effect cycle. The movement speed of the lighting effect is flexibly adjusted according to the length of the light strips, avoiding asynchrony caused by some light strips finishing their effects while others are still in progress due to length differences. For example, when a 3-meter-long light strip along the edge of a tabletop and a 0.5-meter-long light strip along the table leg execute a synchronized flowing lighting effect, the light strip along the tabletop moves faster, while the light strip along the table leg moves slower, but both start flowing simultaneously and complete one flowing cycle at the same time. When the light strips in the functional area of ​​the desktop and the light strips along the side frame of the table execute a synchronized gradient lighting effect, the speed can be adjusted according to the length, but they start gradation simultaneously and transition to the target state simultaneously, ensuring visual harmony and unity.

[0039] Please see Figure 4 In some embodiments of this application, at least two light strips include at least two light strips of different lengths; controlling at least two light strips to synchronously perform dynamic lighting effects along their length includes: S310. Obtain the length characteristic parameters of the light strips; For at least two light strips of different lengths, obtaining the length characteristic parameters is a fundamental prerequisite for achieving luminous efficacy synchronization. This parameter directly reflects the actual length specifications of the light strips, providing accurate data support for subsequent speed adjustments. The system can automatically obtain this parameter by adapting to different light strip types, eliminating the need for manual input and ensuring the convenience and accuracy of parameter acquisition.

[0040] S320. Based on the length characteristic parameters, determine the different light effect movement rates required for each light strip to achieve synchronized light effects. After obtaining the length characteristic parameters, the light effect movement rate of each light strip needs to be determined based on these parameters. The core logic is to achieve a unified cycle and synchronized start and stop light effect through rate adaptation. That is, light strips of different lengths can use different movement rates, but they must complete a full dynamic light effect cycle within the same light effect cycle. The system can first preset a unified light effect cycle, which can be fixed according to the usage scenario requirements or customized by the user. Then, combined with the length characteristic parameters of each light strip, the system calculates the adapted light effect movement rate through a preset algorithm to ensure that the light effect cycle of all light strips remains consistent.

[0041] S330: Drive each LED strip to execute dynamic lighting effects according to the light effect movement rate. After determining the light effect movement rate of each LED strip, the synchronous execution of dynamic lighting effects can be achieved through precise drive control. The core is to ensure that each LED strip runs at the corresponding rate and maintains a high degree of consistency in timing. The controller can output control signals to each LED strip through dual independent output channels. The control signals can include timing synchronization instructions and rate adaptation instructions. Relying on a low-latency communication link, it ensures that all LED strips receive the start command simultaneously without response delay. During the drive process, the output waveform can be dynamically adjusted through the PWM drive circuit to control the rhythm of light effect changes of each LED strip according to the preset rate. For LED strips connected in parallel, such as those on the left and right table legs, the branch current can also be compensated through a constant current balancing module to avoid uneven brightness caused by differences in wire diameter or contact resistance, ensuring the overall synchronization of light effects.

[0042] Please see Figure 5 In some embodiments of this application, the light strip is an addressable light strip, and the length characteristic parameter includes the number of LED chips in the light strip; obtaining the length characteristic parameter of the light strip includes: S311a. Send an addressing query signal to the addressable LED strip. Sending the addressing query signal is a key operation to initiate the identification process for acquiring the length characteristic parameters of the addressable LED strip. This signal is a specific format identification data frame adapted to the communication protocol of the addressable LED strip driver IC. Its core purpose is to trigger the response mechanism of each driver IC inside the LED strip, providing a signal basis for subsequently acquiring the number of LEDs. The controller, as the signal sending entity, outputs this query signal through the signal control terminal connected to the addressable LED strip, ensuring that the signal can completely cover the entire length of the LED strip without any transmission dead zones.

[0043] The operating principle of this step can be summarized around signal generation and transmission adaptation. First, the controller's internal firmware generates an addressing query signal that meets the required format according to the communication protocol of the addressable LED strip (such as the protocol corresponding to WS2811 and WS2812). The signal contains key information such as identification instructions and data length identifiers. Second, the controller stably transmits the addressing query signal to the signal input terminal of the addressable LED strip through a preset signal output channel. Since the addressable LED strip uses serial communication, the query signal is transmitted sequentially along the length of the LED strip, ensuring that each driver IC can receive the signal and trigger a response.

[0044] S312a: Receive response signals from the addressable LED strip. Receiving response signals is the intermediate step connecting query triggering and parameter determination. Its core function is to collect the response feedback from each driver IC within the addressable LED strip, providing raw data for counting the number of LEDs. The response signal is generated by each driver IC within the addressable LED strip and is response data corresponding to the address query signal format. The controller receives this response through the same signal channel connected to the LED strip, ensuring the timeliness and integrity of signal reception.

[0045] The operation of this step follows the logic of signal response, serial transmission, and receive buffering. First, after receiving the addressing query signal, the driver IC in the addressable light strip generates a corresponding response signal according to a preset protocol. Each IC generates an independent response only once to avoid signal duplication. Second, the response signal is serially transmitted back to the controller in reverse order along the signal transmission path according to the arrangement order of the driver ICs in the light strip, ensuring that the controller receives the response of each IC in sequence. Finally, the controller's built-in signal receiving module filters and decodes the transmitted response signal, eliminates interference signals, and temporarily stores the valid response signal in the buffer area, waiting for subsequent counting and statistics.

[0046] S313a. The number of received response signals is determined as the number of LEDs in the addressable LED strip, which is then used as a length characteristic parameter. Determining the number of LEDs is the core output step for obtaining the length characteristic parameter. By statistically analyzing the number of valid response signals, the LED configuration of the addressable LED strip is directly correlated, thus reflecting the actual length of the LED strip. Since each driver IC of the addressable LED strip controls a fixed number of LEDs (e.g., a single IC controls 1 or 3 LEDs), and each IC only feeds back a response signal once, the number of response signals corresponds one-to-one with the number of driver ICs. Combined with the preset IC-LED configuration relationship, the total number of LEDs can be determined.

[0047] The operating principle of this step can be summarized around signal counting, configuration matching, and parameter determination. First, the controller calls the valid response signals stored in the buffer and counts the total number of signals through the built-in counting module to obtain the number of driver ICs. Second, the controller reads the pre-stored addressable LED strip IC and LED chip configuration relationship (e.g., one IC corresponds to one LED chip), multiplies the number of ICs by the configuration relationship, and calculates the total number of LED chips in the LED strip. Finally, the calculated number of LED chips is used as a length feature parameter and stored in the controller's designated storage area to provide direct data support for subsequent calculation of luminous efficacy movement rate.

[0048] For example, the controller sends identification data frames with a length greater than the actual number of ICs to each of the three output channels of the desktop light strip, the left table leg light strip, and the right table leg light strip, such as 200 sets of IC data frames.

[0049] Given the protocol characteristics that each driver IC in an addressable light strip consumes a fixed set of data frames and transmits the remaining data, the controller can logically determine the number of ICs contained in the light strip based on the number of data sets reserved for the light strip and the actual display behavior of the light strip.

[0050] In one specific embodiment, the identification result is as follows: the desktop light strip contains 30 ICs, the left table leg light strip contains 5 ICs, and the right table leg light strip contains 5 ICs. Defining the unit length of the light strip corresponding to a single IC as S, the logical length of the desktop light strip is 30S, the logical length of the left table leg light strip is 5S, and the logical length of the right table leg light strip is 5S. These logical length parameters will be used as input to the subsequent light effect synchronization algorithm to calculate the animation step size and timing rhythm of different light strips.

[0051] Therefore, the controller automatically identifies that the number of light strip points is 30, which can be deduced to be a 3-meter light strip or a 20-point desktop light strip, a 5-point table leg light strip, and a 5-point table leg light strip.

[0052] Please see Figure 6 In some embodiments of this application, obtaining the length characteristic parameter of the light strip includes: S311b: Send a test signal to the LED strip. Sending a test signal to the LED strip is the initial operation for obtaining the length characteristic parameters of the non-addressable LED strip. The core purpose is to provide a signal basis for subsequent parameter measurements by detecting the electrical response feedback of the LED strip. This test signal is a low duty cycle pulse signal, which will not produce visible brightness, avoiding interference with the user's current experience, while accurately stimulating the electrical characteristic response of the LED strip to ensure the validity of the measurement data. The controller, as the main signal transmitter, outputs this test signal through the power output terminal or signal control terminal connected to the LED strip, ensuring that the signal can stably cover the entire LED strip without transmission attenuation or distortion. The controller's internal firmware generates a low duty cycle pulse signal that meets the testing requirements based on the electrical characteristics of the non-addressable LED strip. The signal parameters (such as pulse width and frequency) can be adapted to non-addressable LED strips of different specifications. The controller smoothly transmits the test signal to the input end of the LED strip through a preset output channel. Since the non-addressable LED strip adopts a series-parallel LED layout, the test signal will be evenly applied to all LEDs, causing the LED strip to exhibit the corresponding electrical response, providing a stable test object for subsequent parameter measurements.

[0053] S312b measures the current response amplitude and time constant of the LED strip in response to the test signal. Measuring the current response amplitude and time constant is a core step connecting signal transmission and length determination. The key is to capture the electrical feedback data of the LED strip and extract characteristic parameters directly related to its length. The current response amplitude refers to the peak current generated in the circuit after the LED strip receives the test signal; the time constant refers to the time required for the current to stabilize at a fixed value after startup. Both parameters are closely related to the length of the non-addressable LED strip. The longer the LED strip, the more LEDs, the larger the overall resistance and equivalent capacitance, the smaller the current response amplitude, and the longer the time constant. The controller simultaneously measures and records both parameters through its built-in current detection module and timing module.

[0054] After receiving the test signal, the LED strip forms a current loop. The current detection module captures the current changes in the loop in real time and records the peak value of the current, which is the current response amplitude. The timing module starts timing from the moment the current starts until the current stabilizes within the preset threshold range and records the time of this process, which is the time constant. The controller filters the measured current response amplitude and time constant to remove abnormal data caused by external interference and temporarily stores them in the buffer area to provide clean raw data for subsequent length conversion.

[0055] S313b. Determine the length characteristic parameters of the LED strip based on the current response amplitude and time constant. This step, determining the length characteristic parameters based on the current response amplitude and time constant, is the output step of this identification method. The core is to convert the measured data into characteristic parameters reflecting the actual length of the LED strip by establishing a correspondence between electrical parameters and length. The controller internally stores a database mapping the electrical parameters and lengths of non-addressable LED strips. This database is built based on test data from a large number of non-addressable LED strips of different lengths and specifications, covering the length range or specific values ​​corresponding to different combinations of current response amplitude and time constant. By comparing the two measured parameters with the database, the length characteristic parameters of the LED strip, such as the actual length or logical length, can be determined.

[0056] The controller calls the current response amplitude and time constant stored in the buffer; it uses the two parameters as a combination condition and compares them one by one with the pre-stored mapping relationship database to find the most matching length record; based on the matching result, it determines the length characteristic parameter of the light strip and stores it in the storage area specified by the controller, providing direct data support for the subsequent calculation of the luminous efficacy moving rate.

[0057] Take a typical non-addressable monochrome LED strip as an example. Since the LEDs are connected in series and parallel at fixed intervals, the longer the strip, the more pronounced the differences in overall current and impedance characteristics. During the identification process: the controller first outputs a very low-brightness test pulse (e.g., 10% duty cycle) to avoid brightness being visible to the naked eye and to prevent excessive current from affecting the measurement. The controller measures the instantaneous current value of the LED strip and the time it takes for the current to stabilize to a fixed value (time constant). Based on the current amplitude and time constant, the approximate length of the LED strip can be determined.

[0058] Please see Figure 7 In some embodiments of this application, the table includes a pull-up resistor, and the interface terminal of the light strip has an identification resistor; the pull-up resistor and the identification resistor constitute a voltage divider circuit; obtaining the length characteristic parameter of the light strip includes: S311c: Obtain the voltage at the voltage divider point between the pull-up resistor and the identification resistor in the voltage divider circuit. Obtaining the voltage divider point voltage is a fundamental data acquisition step for identifying the length of the LED strip using a resistor-based voltage divider method. The core is to collect the voltage node data after the pull-up resistor and the identification resistor are connected in series, providing a direct basis for subsequent calculation of the identification resistor value. The table has a built-in pull-up resistor, and the LED strip interface has a preset identification resistor. The two are connected in series to form a voltage divider circuit. The system power supply voltage is fixed, and the voltage divider point voltage will change with the resistance value of the identification resistor. Therefore, this voltage data can directly reflect the specification differences of the identification resistor.

[0059] After the system is powered on, the power supply module of the table outputs a fixed voltage to the voltage divider circuit. The current flows through the pull-up resistor and the identification resistor to form a loop. The controller's built-in ADC sampling module is aligned with the connection node of the pull-up resistor and the identification resistor. The ADC, or analog-to-digital converter, has the core function of converting the analog voltage signal of the voltage divider point into a digital signal that the controller can recognize and collecting the real-time voltage value of the node. During the sampling process, the ADC module will perform multiple samplings and take the average value to eliminate abnormal data caused by voltage fluctuations, ensuring that the collected voltage of the voltage divider point is accurate and stable.

[0060] S312c. Determine the resistance value of the identification resistor based on the voltage divider point. This is a core calculation step connecting voltage acquisition and length determination. The key is to use the voltage divider principle to deduce the unknown identification resistor value from known parameters, establishing a relationship between voltage data and resistor specifications. In the system, the power supply voltage and pull-up resistor value are pre-stored fixed parameters. According to the voltage divider formula, the voltage divider point voltage and the identification resistor value are positively correlated; therefore, the actual resistance value of the identification resistor can be accurately calculated using this formula.

[0061] S313c: Based on the predefined correspondence between resistance values ​​and LED strip specifications, determine the length characteristic parameters of the LED strip. Determining the length characteristic parameters based on the correspondence between resistance values ​​and LED strip specifications is the output step of this identification method. The core is to convert the resistance value of the identification resistor into a characteristic parameter reflecting the actual length of the LED strip, completing the conversion from electrical parameters to physical specifications. The controller internally stores a mapping table between resistance values ​​and LED strip specifications. This table is established based on a large amount of test data from LED strips of different lengths, clearly defining the LED strip length or the number of LEDs corresponding to different identification resistor values.

[0062] In some embodiments of this application, the controller's storage module pre-stores a "lookup table" that defines the LED strip specifications corresponding to different voltage ranges (or ADC value ranges). Higher voltage results in a higher identification resistance, indicating a shorter LED strip; lower voltage results in a lower identification resistance, indicating a longer LED strip. After identification, the firmware packages the LED strip configuration parameters (such as length L, number of LEDs N, and IC type T) and reports them to the control system.

[0063] Assuming the system power supply is 5V and the pull-up resistor is 10kΩ; the identification resistor at the LED strip terminal is configured according to the actual product as follows: LED strip type Actual length Identifier resistor R-ID Sampling voltage V_s Firmware identification results Table leg light strip 0.5m 47kΩ Approximately 4.1V Short LED strip: 5 LED beads Desktop light strip 3.0m 10kΩ Approximately 2.5V Long LED strip: 30 LED beads After reading the ADC, the controller firmware can make the following judgments: The ADC voltage is approximately 4.1V, and the R-ID has a high resistance value, indicating a short LED strip (0.5m). The ADC voltage is approximately 2.5V, and the R-ID has a low resistance value, indicating a long LED strip (3m).

[0064] Please see Figure 8In some embodiments of this application, determining the different light effect movement rates required for each light strip to achieve light effect synchronization based on length characteristic parameters includes: S321. Define one of at least two LED strips of different lengths as the standard LED strip. The choice of the standard LED strip is not limited to a fixed length; it can be customized according to actual needs, taking either of the two strips of different lengths. This includes the shortest strip, the longest strip, and if there are three or more strips, a strip of intermediate length can also be selected. The essence of defining a standard LED strip is to establish a unified reference anchor point for the luminous efficacy cycle. The luminous efficacy parameters of all other LED strips will be adapted around this anchor point, ensuring the coordination of synchronized luminous efficacy across multiple strips.

[0065] S322. Calculate the luminous efficacy period of other light strips based on the ratio of the length characteristic parameters of the standard light strip to those of at least two other light strips of different lengths, and the luminous efficacy period of the standard light strip. First, retrieve the length characteristic parameters and preset luminous efficacy period of the standard light strip, and simultaneously obtain the length characteristic parameters of each of the other light strips. Calculate the ratio of the length characteristic parameters of the standard light strip to those of each of the other light strips (e.g., standard light strip length / other light strip length). Then, multiply this ratio by the luminous efficacy period of the standard light strip to calculate the appropriate luminous efficacy period for the corresponding other light strips.

[0066] S323. Adjust the luminous efficacy movement rate of other LED strips according to the luminous efficacy cycle of the standard LED strip, so that the luminous efficacy cycle of the other LED strips is consistent with that of the standard LED strip. This step is the final execution step to achieve luminous efficacy synchronization of multiple LED strips. The core is to compensate for the luminous efficacy asynchrony caused by length differences by dynamically adjusting the rate, ensuring that all LED strips start and end their luminous efficacy cycles at the same time. The luminous efficacy movement rate satisfies the following relationship with the LED strip length and luminous efficacy cycle: Rate = Length / Cycle. Given that the luminous efficacy cycle of the standard LED strip is determined, the adaptation rate of other LED strips can be calculated backward using this formula.

[0067] When the standard LED strip is the longest, the adaptation rate of other shorter LED strips will be reduced accordingly to prevent premature end of the light effect due to short length and excessively fast speed. When the standard LED strip is the shortest, the adaptation rate of other longer LED strips will be increased accordingly to prevent lag in the light effect due to long length and excessively slow speed. When the standard LED strip is of medium length, longer LED strips need to increase their speed, and shorter LED strips need to decrease their speed, so that the light effect cycle of all LED strips is consistent with the medium standard. Through this targeted speed adjustment, regardless of how the standard LED strip is customized, the effect of LED strips of different lengths completing the light effect cycle synchronously can be achieved visually, enhancing the overall integrity and coordination of the light effect.

[0068] In some embodiments, the luminous efficacy period of all the light strips on the table may be unknown. In this case, a known reference light strip can be introduced. The reference light strip is a reference carrier preset by the system. Its length characteristic parameters and luminous efficacy period are fixed. By using the known length characteristic parameters and luminous efficacy period of the reference light strip, combined with the length characteristic parameters of the standard light strip and other light strips, the luminous efficacy period and luminous efficacy movement rate of the standard light strip and other light strips can be calculated.

[0069] The standard light strip can be any light strip on the table. In some embodiments, the longest light strip is selected as the standard light strip. The longest light strip is the longest light strip on the table that has been selected through the previous length recognition step. The ratio of the length characteristic parameters of the two directly determines the luminous efficacy period adaptation value of the longest light strip.

[0070] The system retrieves pre-stored reference light strip length characteristic parameters and luminous efficacy period, and simultaneously calls the length characteristic parameters of the longest light strip among the previously identified light strips on the table. It calculates the ratio of the length characteristic parameters of the reference light strip to those of the longest light strip, and then combines this ratio with the luminous efficacy period of the reference light strip to calculate the luminous efficacy period of the longest light strip. The calculation result is stored in the controller for subsequent use. Typically, the longest light strip has the longest luminous efficacy period. Compared to shortening the luminous efficacy period, increasing the luminous efficacy movement rate, extending the luminous efficacy period, and slowing down the luminous efficacy movement rate are easier to implement. Therefore, using the longest light strip as the standard light strip can significantly reduce the controller's computational and driving pressure, reducing the risk of luminous efficacy stuttering and misalignment. At the same time, all shorter light strips only need to slow down their rate to follow its cycle to easily achieve synchronized start and stop, resulting in a more visually harmonious and smooth appearance. It also simplifies the system calibration logic and improves overall operational stability.

[0071] In some embodiments, timing mapping and rate compensation mechanisms can be introduced into the output control. Timing mapping refers to the controller mapping a uniform light effect period T to logical pixel sequences of light strips of different lengths. By scaling the animation playback speed, frame interval, and PWM change timing, light strips of different lengths can execute corresponding light effect steps at the same time node, thereby achieving light effect synchronization.

[0072] The controller defines the light effect movement speed as: Vi

[0073] Vi is the luminous efficiency shift rate of the i-th LED strip. The time required for the corresponding light strip to complete one light effect cycle.

[0074] Taking the longest LED strip as the standard LED strip as an example, in order to maintain visual synchronization (i.e., the light efficacy of LED strips of different lengths completes one cycle at the same time), the controller calculates a scaling factor:

[0075] in Given the luminous efficacy period of a known reference LED strip, This is the longest light strip length. Through this rate compensation algorithm, the controller dynamically adjusts the PWM waveform or data frame transmission interval during output, making the light effect change rate of the short light strip slower, maintaining visual rhythm consistent with the long light strip.

[0076] Taking a light effect period of T = 3 seconds as an example, the light effect speed of a 3.0-meter desktop light strip needs to be 1.0 m / s, while the light effect speed of a 0.5-meter table leg light strip only needs to be 0.167 m / s. The controller automatically calculates the light effect speed based on the strip length, enabling the long and short light strips to complete the dynamic effect within the same period, thus achieving visual synchronization. The final visual effect appears as if they move synchronously from beginning to end.

[0077] Based on the above-described table lighting control method, this application also provides a table, which: Table body; Multiple light-emitting units; multiple light-emitting units are installed on the table; Controller; The controller is configured to execute the table lighting control method in any of the above embodiments to control the lighting state of multiple light-emitting units.

[0078] The table serves as the basic load-bearing structure, providing stable mounting support for multiple light-emitting units and controllers. Its structural design is adaptable to various usage scenarios such as office work, e-sports, and study, meeting the needs of different environments. It also allows for the rational layout of the light-emitting units, ensuring that the light can cover key visual areas around the table. Multiple light-emitting units, acting as the actuators for light output, are strategically positioned in different parts of the table. Common installation methods include: For tabletop edges and outer legs, a strip light can be installed around the tabletop edge, and a strip light can be installed along the length of the outer legs; For the front edge of the tabletop and the supporting beam underneath, a strip light is embedded inward at the front edge to illuminate the work surface, and a strip light is installed on the beam underneath to create a floor atmosphere; For the central functional area of ​​the tabletop and the side frame, a strip light is installed below the central functional area to provide localized lighting, and a strip light is installed vertically on the side frame to enhance the three-dimensional visual effect; For height-adjustable desks, a strip light is installed on the bottom of the tabletop and the sides of the height-adjustable column to avoid shadows on the desktop, and a strip light is installed on the sides of the height-adjustable column to respond to the height adjustment; For gaming desks, a strip light is installed on the edge of the keyboard area and the monitor bracket beam, with a strip light on the keyboard edge adapting to the operating angle, and a strip light on the monitor bracket beam to supplement the illumination around the screen; For study desks, a strip light is installed below the reading / writing area and on the inner side of the legs, with a strip light below the reading / writing area providing uniform lighting to protect eyesight, and a strip light on the inner side of the legs to avoid interference from direct ground light.

[0079] The controller is the core control component of this table lighting system. It is configured to execute the table lighting control method in any of the above embodiments, becoming a key hub connecting the table state, user operation, and the light-emitting state of the light-emitting units. It can receive various trigger signals, including control signals related to table movements and user interaction signals, and match the corresponding lighting change modes according to preset logic. Then, through precise drive control, it adjusts the light-emitting state of multiple light-emitting units to ensure that the lighting effect meets expectations and improves the user's interactive experience.

[0080] Please see Figure 1 and Figure 2 In some embodiments of this application, the table body includes a tabletop 1 and lifting table legs 2 that support the tabletop 1, and multiple light-emitting units include a desktop light strip 3 disposed on the tabletop 1 and a table leg light strip 4 disposed on the lifting table legs 2; The controller is configured as follows: Obtain the lifting action signal of the adjustable table legs; Based on the lifting action signal, control the desktop light strip and the table leg light strip to perform synchronized lighting effects.

[0081] The tabletop 1, serving as the primary area of ​​use, provides the mounting base for the desktop light strip 3. The adjustable table legs 2 not only support the tabletop and allow for height adjustment, but also provide a suitable mounting surface for the table leg light strip 4. Together, they form the basis of the dual-light strip layout, allowing the light to cover the desktop work area and the surrounding area of ​​the table legs, creating a three-dimensional visual effect. The desktop light strip 3 and table leg light strip 4, as core light-emitting units, cater to different lighting and ambiance needs. For example, the desktop light strip 3 can focus on auxiliary lighting or ambiance rendering in the work area, while the table leg light strip 4 can enhance the sense of spatial layering. Together, they create a more immersive lighting effect.

[0082] The controller, in conjunction with the control module of the height-adjustable table, accurately acquires the lifting and lowering motion signals of the table legs. These signals include both lifting commands issued by the user via a handheld controller or app, and status feedback signals from the lifting mechanism during operation, ensuring real-time perception of the lifting motion. Upon receiving a lifting motion signal, the controller invokes a pre-stored mapping relationship between motion and lighting effects, matching the corresponding synchronized lighting effect mode based on the signal type.

[0083] In some embodiments, the lighting behavior corresponding to the lifting operation of the table legs includes the desktop light strip waking up and flowing, the table leg light strip gradually brightening from bottom to top or producing an upward flowing light effect; the lighting behavior corresponding to the lifting operation of the table legs lowering includes the desktop light strip waking up and flowing, the light shrinking or dimming from top to bottom, simulating energy falling back; the lighting behavior corresponding to the stopping operation of lifting includes the light smoothly transitioning to a stable brightness or a slow breathing state.

[0084] Please see Figure 9In some embodiments of this application, the controller 5 adopts a dual-output structure, one of which is a desktop light strip signal line 31 and the other is a table leg light strip signal line 41. The table leg light strip signal line 41 is further divided into a left leg light strip signal line 411 and a right leg light strip signal line 412, so as to realize independent driving and linkage control of the desktop light strip 3 and the table leg light strip 4.

[0085] Please see Figure 10 In some embodiments of this application, the table control system mainly includes: Power module: Provides a unified 5V DC power input to power the LED strips (desktop LED strips, table leg LED strips); Adjustable desk controller: Used to receive user commands (lifting, lowering, lighting control).

[0086] LED strip controller: The core control module, featuring dual-channel PWM or constant voltage output.

[0087] First output (CH1): Connects to desktop light strip; Second output (CH2): Connects to the table leg light strip; The parallel connection structure of the light strip signal line and power line on the table leg ensures that the light strips on both sides of the table leg light up simultaneously and that the voltage and signal direction are consistent.

[0088] Please see Figure 11 In some embodiments of this application, the core principle of the table control system is that while the hand controller of the height-adjustable table provides power to the light strip controller, a control signal channel is established between the two using wireless communication technology. This allows the lighting system to synchronously sense the table's movement and make corresponding light changes when the height-adjustable table performs a height-adjustment operation. The system adopts a "wired power supply, wireless control" structure, meaning that only a power connection is maintained between the hand controller and the light strip controller, and the control signal is transmitted through a wireless module. Real-time linkage between the height-adjustment action and the light effect response can be achieved without adding extra wiring.

[0089] The power supply and signal connection follow a specific logic. The main power path is provided by the main power module of the height-adjustable desk, which provides a 29V DC input. This power supply powers both the main control system of the height-adjustable desk and the hand controller. The hand controller of the height-adjustable desk integrates a DC-DC step-down module, which can regulate and reduce the input 29V voltage to 5V, and then output it through a standard USB interface to power the light strip controller. The light strip controller only receives 5V power input through the USB interface and does not participate in the high-voltage circuit of the height-adjustable system, effectively ensuring safety and electrical isolation. This structure allows the lighting system to be directly embedded in the existing height-adjustable desk without the need for an additional adapter.

[0090] The signal transmission and control process is clearly defined. During the wireless communication channel establishment phase, both the handheld controller and the light strip controller have built-in wireless communication modules, supporting Bluetooth Low Energy (BLE) or 2.4GHz RF communication. Upon system power-up, the handheld controller automatically initiates pairing, and the light strip controller enters listening mode. After successful pairing, a low-latency communication link is established to transmit lifting and lowering commands. This low-latency link uses point-to-point real-time communication, with a connection interval set between 7.5ms and 20ms. Each interaction completes command transmission and confirmation within a single transmission cycle. When the user presses the lifting button, the control command is transmitted to the light strip controller via the wireless link within milliseconds. The controller immediately parses and executes the corresponding lighting response, ensuring that the light effect changes and lifting / lowering movements are synchronized. Near synchronization ensures stable and rapid command response even in network-free environments, significantly improving real-time interaction and user experience. In the motion signal recognition stage, when the user performs lifting operations on the hand controller or controls the table's rise, fall, and stop via the app, the hand controller, in addition to controlling the main controller to complete the mechanical movements, encodes the corresponding motion signals into command packets and sends them to the light strip controller via the wireless module. The rising operation corresponds to the desktop light strip activating a flowing effect, the table leg light strip gradually brightening from bottom to top, or producing an upward flowing light effect. The falling operation corresponds to the desktop light strip activating a flowing effect, the light contracting or dimming from top to bottom to simulate energy falling back. The stop operation corresponds to the light smoothly transitioning to a stable brightness or a slow breathing state. The light strip controller has two output channels, CH1 and CH2, which drive the desktop light strip and table leg light strip respectively, achieving various light effect changes such as brightness gradients and directional flowing through PWM signals.

[0091] This embodiment eliminates the wired signal connection between the hand controller and the light strip controller. The system only needs a single USB power cable to achieve power sharing and signal transmission, making the overall wiring simpler and reducing installation difficulty and maintenance costs.

[0092] The control path in this embodiment includes: Power path: The connection from the main power supply to the LED strip controller is wired; Signal path: The connection from the hand controller to the light strip controller is wireless. Lighting output path: The light strip controller drives two light strips respectively, and the table leg light strips adopt a left-right parallel structure.

[0093] This structure achieves physical decoupling between power supply and control signals, reducing wiring complexity while improving system security and scalability.

[0094] This embodiment, while achieving physical decoupling between the power supply path and the control signal path, also possesses significant structural and industrialization advantages: The LED strip controller and LED strip assembly in this embodiment employ a modular electrical connection structure to achieve dual-path independent drive, rapid installation, and safety protection. The LED strip controller has two independent output interfaces, corresponding to desktop LED strips and table leg LED strips respectively. Each output includes a power output terminal and a signal control terminal, employing a pluggable or magnetic connection structure, supporting blind insertion in both directions to prevent misinsertion or reverse polarity. The LED strip controller internally incorporates current limiting protection, current detection, and reverse protection circuits to automatically disconnect the output in case of wiring errors or abnormal loads, ensuring safe system operation.

[0095] The table leg LED strip uses a parallel wiring structure on both sides to ensure consistent brightness and color temperature. A constant current balancing module is installed in the output circuit to automatically compensate for the current in the left and right branches, thereby eliminating uneven brightness caused by differences in wire diameter or changes in contact resistance.

[0096] In addition, the interface has reserved identification pins or data contacts. The controller can identify the type of light strip (such as monochrome light strip, RGB light strip or addressable light strip) based on the internal parameters of the light strip and automatically match the corresponding PWM control algorithm and output curve to achieve intelligent self-adaptation function.

[0097] Please see Figure 12 , Figure 13 , Figure 14 and Figure 15 The lifting table leg 2 is provided with a first hook part 21, and the table leg light strip 4 includes a housing 40. The housing 40 is provided with a clearance groove 42 on the side facing the lifting table leg 2. A second hook part 43 is provided in the clearance groove 42. The first hook part 21 and the second hook part 43 are hooked together.

[0098] In this embodiment, the first hook part 21 is disposed on the lifting table leg 2 as a fixed structure for hooking and supporting. Its shape needs to be adapted to the installation requirements of the table leg light strip 4 to ensure the stability after hooking. The second hook part 43 is located in the relief groove 42 on the side of the table leg light strip 4 facing the lifting table leg 2. The relief groove 42 not only provides a space for the first hook part 21 to avoid interference between the hooking structure and the housing 40 or internal components of the light strip, but also makes the hooking more precise by limiting the groove.

[0099] The first hook-on part 21 serves as a fixed end, providing support and guidance. The second hook-on part 43 serves as a matching end, engaging with it one-to-one. During assembly, the guiding characteristics of the first hook-on part 21 allow for quick alignment and hooking of the second hook-on part 43. A tight lock is then achieved through the weight of the light strip itself or a slight downward pressure. Disassembly requires only applying a reverse force to release the hook-on, eliminating the need for additional tools and balancing installation efficiency with ease of maintenance. Simultaneously, the fit between the recessed groove 42 and the hook-on part ensures that the table leg light strip 4 fits snugly against the surface of the lifting table leg 2, preventing loose fit caused by protrusions in the hook-on structure. This improves visual neatness and reduces the swaying of the light strip during the lifting and lowering of the table leg.

[0100] For example, the first hook 21 can be a hook welded or pasted onto the lifting table leg 2. The hook has a guide structure at a certain angle, which can guide the second hook 43 to quickly align and avoid misalignment during assembly. The corresponding second hook 43 can be a cut in the recess 42 of the table leg light strip 4. The size of the cut is precisely matched with the shape of the hook. During assembly, simply align the cut with the hook and hang it along the guide angle. The weight of the light strip will cause the hook and the cut to gradually lock together, forming a stable connection. When disassembling, push the light strip upward to release the engagement.

[0101] It should be noted that this type of hanging structure is not the only solution; the table leg light strip 4 can also be fixed by clips or magnetic means.

[0102] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
