Researchers are committed to improving the control accuracy and response speed of lighting fixtures, optimizing the white balance adjustment process through intelligent algorithms, realizing the function of distance communication, extending the service life of equipment and reducing maintenance costs. White balance lamps are usually used to provide lighting with different color temperatures to simulate natural light or meet specific lighting needs. However, most of them have not solved how to generate feedback information by detecting the intensity and color temperature of ambient light, and control the brightness and color temperature of white balance lamps according to the feedback information to generate control signals to achieve white balance adjustment.

Due to the presence of the above-mentioned functional modules, the lamp has the functions of audio playback, image and audio pickup, and therefore, the lamp can be used in a variety of actual usage scenarios.

[0005] The above patents have the problems raised by the background technology: the above lamps and lamp control systems connect the control circuit and the functional module through a hub, and realize the functions of audio playback, image and audio pickup through at least one of the audio playback module, image acquisition module and sound pickup module in the functional module, so that the lamp can be used in a variety of practical usage scenarios; the above lamp control system emits a first light-emitting mode of therapeutic light for improving the user's health through the light-emitting module, and detects the user's vital signs in the first light-emitting mode through the detection module, and controls the light emission of the lamp according to the detection results. The above two patents do not solve the problem of how to generate feedback information by detecting the intensity and color temperature of the ambient light, and control the brightness and color temperature of the white balance lamp according to the feedback information to generate a control signal to achieve white balance adjustment.

[0054] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0055] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0056] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0057] Example 1

[0058] In this embodiment, a system structure diagram of a white balance lamp control system based on wireless communication is provided, such as Figure 1 As shown, the white balance lamp control system based on wireless communication includes a sensor module, a lamp control module, a wireless communication module, a power management module and a scene setting module.

[0059] The sensor module is used to detect the intensity and color temperature of ambient light and generate feedback information.

[0060] The intensity and color temperature of the ambient light are detected by the sensor, and the intensity of the ambient light is calculated by the output voltage of the sensor. The calculation formula for the intensity of the ambient light is as follows:

[0061] i = k × v;

[0062] Where i represents the intensity of ambient light, k represents the sensitivity constant of the sensor, and v represents the output voltage of the sensor.

[0063] It should be noted that the sensitivity constant k of the sensor is a parameter related to the characteristics of the sensor itself. Different sensors have different sensitivity constants. This constant reflects the ability of the sensor to convert light signals into electrical signals (output voltage), that is, the proportional relationship between the output voltage change caused by a unit change in light intensity.

[0064] The function expression of the color temperature of ambient light is as follows:

[0065]

[0066] Where ct represents the color temperature of the ambient light, R represents the red light intensity read by the sensor, G represents the green light intensity read by the sensor, and B represents the blue light intensity read by the sensor.

[0067] It needs to be explained that 1000 refers to the constant used to convert RGB values ​​to Kelvin units, which represents the magnitude of color temperature.

[0068] The intensity of ambient light is measured by the light intensity sensor, the color temperature of ambient light is detected by the color temperature sensor, the sensor module is connected to the microcontroller, code is written to initialize the light intensity sensor and the color temperature sensor, the sampling rate of the light intensity sensor and the color temperature sensor are configured, the output value of the light intensity sensor is read, and the intensity of ambient light is calculated according to the formula. At the same time, the RGB value of the color temperature sensor is read, and the color temperature of ambient light is calculated according to the formula. The values ​​of the intensity and color temperature of ambient light are formatted into easy-to-understand information, which is the feedback information.

[0069] The lamp control module is used to control the brightness and color temperature of the white balance lamp according to the feedback information and generate a control signal to achieve white balance adjustment.

[0070] like Figure 2 As shown, the feedback information is analyzed, including the intensity and color temperature of the ambient light, the standard brightness and standard color temperature are configured, the brightness adjustment amount and the color temperature adjustment amount of the white balance lamp are calculated, and a control signal is generated according to the brightness adjustment amount and the color temperature adjustment amount of the white balance lamp.

[0071] The function expression of the brightness adjustment amount of the white balance lamp is as follows:

[0072] Δl=k l ×(Δb+λ1×|Δb| 2 ×sgn(Δb));

[0073] Where Δl represents the brightness adjustment of the white balance lamp, k l represents the brightness adjustment factor, Δb represents the difference between the standard brightness and the current brightness, λ1 represents the brightness amplitude coefficient, and sgn(Δb) represents the sign function of the brightness adjustment.

[0074] What needs to be explained is: brightness adjustment factor k l Used to control the brightness adjustment of white balance lamps, with a value between 0 and 1, |Δb| 2 It represents the square of the absolute value of Δb, emphasizing the impact of large brightness difference on brightness adjustment. The brightness amplitude coefficient λ1 is used to control the amplitude of brightness adjustment, and its value is usually a small constant, such as 0.03. The sign function sgn(Δb) of brightness adjustment is used to maintain the adjustment direction of the brightness adjustment of the white balance lamp, and its value range is {-1,0,1}. When sgn(Δb)=-1, the brightness needs to be reduced. When sgn(Δb)=0, it indicates that the brightness is at the standard brightness. When sgn(Δb)=1, the brightness needs to be increased.

[0075] In the actual white balance lamp control system, it is necessary to adjust the brightness of the lamp in real time according to the changes in ambient light to achieve the ideal lighting effect. When the ambient light changes and causes the current brightness to deviate from the standard brightness, that is, Δb is not 0, the control system needs to calculate the brightness adjustment Δl of the white balance lamp based on this difference Δb; the brightness adjustment factor k l The brightness adjustment range can be flexibly adjusted according to different application scenarios and needs. For example, in some scenarios where the brightness change is required to be relatively gentle, such as bedroom lighting, a smaller k can be set. l In some scenes that require a quick response to brightness changes, such as stage lighting, a larger k value can be set. l value.

[0076] |Δb| 2 The addition of the term is to highlight the adjustment amount when the brightness deviation is large. When the brightness deviation is small, |Δb| 2 The value of is relatively small, and the influence on the brightness adjustment is also small, and the adjustment of the brightness of the lamp is relatively gentle. When the brightness deviation is large, |Δb| 2The value of increases rapidly, so that the brightness adjustment amount also increases accordingly, so that the brightness of the lamp is quickly adjusted to the standard brightness level, which can ensure the stability of the brightness adjustment while improving the response speed and adjustment efficiency to large brightness changes; the brightness amplitude coefficient λ1 can further adjust the sensitivity and adjustment amplitude of the brightness adjustment amount to the brightness difference according to different application scenarios, so as to achieve fine control of the brightness adjustment amplitude; and the sign function sgn(Δb) is to ensure the correctness of the direction of the brightness adjustment, and whether to increase or decrease the brightness is determined according to the positive or negative value of sgn(Δb), so that the lamp can be accurately adjusted in the direction of the standard brightness.

[0077] Similarly, the function expression of the color temperature adjustment amount of the white balance lamp is as follows:

[0078] Δct=k c ×(Δt+λ2×Δt 2 ×sgn(Δt));

[0079] Where Δct represents the color temperature adjustment of the white balance lamp, k c represents the color temperature adjustment factor, Δt represents the difference between the standard color temperature and the current color temperature, λ2 represents the color temperature amplitude coefficient, and sgn(Δt) represents the sign function of the color temperature adjustment.

[0080] What needs to be explained is: color temperature adjustment factor k c Used to control the color temperature adjustment amplitude of the white balance lamp, with a value between 0 and 1, Δt 2 It means that the greater the color temperature difference, the more significant the impact of the adjustment; the color temperature amplitude coefficient λ2 is used to control the amplitude of the color temperature adjustment amount, and its value is usually a small constant, such as 0.08; the sign function sgn(Δt) of the color temperature adjustment is used to maintain the adjustment direction of the color temperature adjustment amount of the white balance lamp, and its value range is {-1,0,1}. When sgn(Δt)=-1, the color temperature needs to be lowered. When sgn(Δt)=0, it means that it is already at the standard color temperature. When sgn(Δt)=1, the color temperature needs to be increased.

[0081] Similar to the formula for brightness adjustment, the formula for color temperature adjustment is also designed to enable white balance lamps to be adaptively adjusted according to changes in the color temperature of ambient light. In different lighting environments, people's perception and demand for color temperature are also different. For example, people usually prefer higher color temperatures (colder tones) during the day, and lower color temperatures (warmer tones) at night. Therefore, a formula that can accurately and sensitively adjust color temperature is needed.

[0082] Color temperature adjustment factor k c The role of brightness adjustment factor k lSimilarly, the color temperature adjustment range can be adjusted according to specific application scenarios and user preferences. For example, for art exhibition venues that are more sensitive to color temperature changes, a smaller k value needs to be set. c value to achieve fine color temperature adjustment; for some ordinary office spaces that do not have strict requirements on color temperature, a relatively large k value can be set. c value to speed up the color temperature adjustment.

[0083] Δt 2 The existence of the term enables the color temperature adjustment to increase rapidly when the color temperature difference is large, thereby quickly correcting the large color temperature deviation and making the color temperature of the lamp approach the standard color temperature more quickly. This helps to quickly create a lighting atmosphere that meets the user's expectations when the ambient color temperature changes significantly; the color temperature amplitude coefficient λ2 can better adapt to the diverse needs for color temperature adjustment in different scenarios, and further control the amplitude of the color temperature adjustment, so that the color temperature adjustment is more in line with the needs of practical applications; the sign function ensures the directionality of the color temperature adjustment, and determines whether to increase or decrease the color temperature based on the positive or negative difference between the standard color temperature and the current color temperature, thereby ensuring the accuracy and effectiveness of the color temperature adjustment.

[0084] After parsing the feedback information, the current brightness of the white balance lamp is adjusted according to the intensity of the ambient light, and the current color temperature of the white balance lamp is adjusted according to the color temperature of the ambient light. The brightness adjustment amount and color temperature adjustment amount of the white balance lamp are calculated according to the above formula. According to the brightness adjustment amount and color temperature adjustment amount obtained by solving the solution, a control signal is generated, including a brightness adjustment signal, a color temperature adjustment signal, a mode switching signal, a power diagnosis signal, a status feedback signal and a synchronization signal, and the adjustment of the white balance lamp is controlled, wherein the adjustment of the color temperature of the white balance lamp is changed by fluorescent materials, so that the color temperature emitted by the white balance lamp can be close to the natural light color.

[0085] At the same time, in addition to the brightness adjustment signal and color temperature adjustment signal for adjusting the brightness and color temperature of the white balance lamp, the mode switching signal refers to supporting different lighting modes, such as reading mode and leisure mode, etc. These lighting modes usually preset a set of brightness and color temperature combinations of white balance lamps to meet specific scene requirements, and users select through custom options; the power diagnosis signal means that if the white balance lamp is detected to have an abnormal power status, the lamp control module will generate a power diagnosis signal, which can help technicians quickly locate the problem and perform repairs in time; in addition to sending color temperature adjustment signals and brightness adjustment signals to the white balance lamp, the lamp control module will also receive status feedback signals from the white balance lamp to confirm whether the white balance lamp executes the color temperature adjustment signal and the brightness adjustment signal correctly. The status feedback signal is crucial to ensuring the reliability and stability of the system; in addition, in order to ensure the color consistency of all white balance lamps, a synchronization signal needs to be sent to ensure that the white balance lamps adjust the color temperature or brightness at the same time.

[0086] The wireless communication module is used to establish wireless communication of the white balance lighting control system to ensure that the control signal and feedback information can be effectively transmitted in the network.

[0087] The specific steps to establish wireless communication of the white balance lighting control system include:

[0088] Monitor the signal strength, signal-to-noise ratio and bit error rate of wireless communication, configure the standard signal, standard signal-to-noise ratio and standard bit error rate. If the signal strength of wireless communication is greater than or equal to the standard signal, the signal strength of wireless communication is the signal strength extreme value.

[0089] If the signal strength of the wireless communication is less than the standard signal, the signal strength of the wireless communication is the base signal strength value;

[0090] If the bit error rate of wireless communication is greater than or equal to the standard bit error rate, then the bit error rate of wireless communication is the extreme bit error rate;

[0091] If the bit error rate of wireless communication is less than the standard bit error rate, the bit error rate of wireless communication is the bit error rate base value;

[0092] Dynamically adjust the transmission rate according to the signal strength and bit error rate of wireless communication, if the signal strength of wireless communication is the signal strength extreme value and the bit error rate of wireless communication is the bit error rate base value, then increase the transmission rate;

[0093] If the signal strength of the wireless communication is the base signal strength value and the bit error rate of the wireless communication is the extreme bit error rate value, the transmission rate is reduced to avoid the loss of data packets.

[0094] Configure the transmission rate limit and dynamically adjust the transmission rate logic including:

[0095] Determine standard signal-to-noise ratio and rate adjustment factor;

[0096] Obtaining a current signal-to-noise ratio of wireless communication;

[0097] Dividing the current signal-to-noise ratio value of the wireless communication by the standard signal-to-noise ratio value to obtain a signal-to-noise ratio value;

[0098] The signal-to-noise ratio value, the transmission rate extreme value and the rate adjustment factor are processed to obtain the adjusted current transmission rate.

[0099] The function expression for dynamically adjusting the transmission rate is as follows:

[0100]

[0101] In the formula, s represents the current transmission rate, s max represents the transmission rate limit, SNR represents the current signal-to-noise ratio of wireless communication, SNR0 represents the standard signal-to-noise ratio, and α represents the rate adjustment factor.

[0102] What needs to be explained is: the transmission rate extreme value s max It refers to the highest transmission rate that can be achieved under the best channel conditions. The standard signal-to-noise ratio SNR0 refers to the lowest signal-to-noise ratio that can be transmitted reliably. The signal-to-noise ratio refers to the ratio of signal strength to noise strength, reflecting the quality of the signal. The rate adjustment factor α reflects the nonlinear relationship between the transmission rate and the signal-to-noise ratio, and usually takes a value between 0 and 1. The smaller the rate adjustment factor α, the lower the sensitivity of the transmission rate to the signal-to-noise ratio.

[0103] The channel conditions are evaluated by monitoring the signal strength, signal-to-noise ratio and bit error rate of wireless communications. A comprehensive judgment is made based on the signal strength and bit error rate of wireless communications whether the transmission rate needs to be adjusted and how to adjust it. For example, when the signal strength of wireless communications is the signal strength extreme value and the bit error rate of wireless communications is the bit error rate base value, the transmission rate needs to be increased. When the signal strength of wireless communications is the signal strength base value and the bit error rate of wireless communications is the bit error rate extreme value, the transmission rate needs to be reduced. The current transmission rate of the control signal is calculated through the formula for dynamically adjusting the transmission rate. At the same time, it is ensured that the adjustment of the transmission rate is within the acceptable transmission rate range. Each time the channel conditions change, the signal strength and bit error rate are recalculated, and the transmission rate is adjusted according to the above calculation formula to ensure that the control signal and feedback information can be effectively transmitted in the network.

[0104] The power management module is used to manage the power of the white balance lamp.

[0105] The strategy for managing the power supply of white balance lamps includes state monitoring logic and energy-saving logic. The state monitoring logic is used to monitor the power level and health status of the white balance lamps in real time and set multi-level alarms; the energy-saving logic is used to monitor the temperature of the white balance lamps and adjust the power current according to the temperature of the white balance lamps.

[0106] Condition monitoring logic such as Figure 3 As shown, specifically including:

[0107] The remaining power of the power supply of the white balance lamp is calculated in real time through the monitoring results of the current sensor and the voltage sensor, and the remaining capacity of the power supply of the white balance lamp is calculated by recording the number of charge and discharge times, capacity attenuation and initial capacity of the power supply of the white balance lamp, so as to obtain the health status result of the power supply of the white balance lamp, and set a multi-level alarm, configure the power base value and critical power. If the remaining power of the power supply of the white balance lamp is less than or equal to the power base value, a low power alarm is triggered;

[0108] If the remaining power of the power supply of the white balance lamp is less than or equal to the critical power, the critical power alarm is triggered.

[0109] Among them, the value of the base power is larger than the value of the critical power. When it is lower than the critical power, it needs to be charged immediately.

[0110] The calculation formula for the remaining power of the white balance lamp is as follows:

[0111] D = ∫I(r)dr×E(r);

[0112] Wherein, D represents the remaining power of the power supply of the white balance lamp, I(r) represents the current of the power supply of the white balance lamp at time point r, and E(r) represents the voltage of the power supply of the white balance lamp at time point r.

[0113] The calculation formula for the remaining capacity of the power supply of the white balance lamp is as follows:

[0114] c = c0 - c′ × n;

[0115] In the formula, c represents the remaining capacity of the power supply of the white balance lamp, c0 represents the initial capacity of the power supply of the white balance lamp, c' represents the capacity attenuation of the power supply of the white balance lamp, and n represents the number of charge and discharge times of the power supply of the white balance lamp.

[0116] It should be explained that: ∫I(r)dr represents the integration of the current at a point in time, and the total amount of charge or discharge is calculated. The capacity decay c' of the power supply of the white balance lamp represents the capacity decay caused by each charge and discharge.

[0117] The health status of the power supply of the white balance lamp is obtained by calculating the remaining power and the remaining capacity of the power supply. When the remaining capacity of the power supply of the white balance lamp is less than the capacity threshold, it means that the health status of the power supply of the white balance lamp is not good and a new power supply needs to be replaced to maintain the normal function of the white balance lamp.

[0118] Energy-saving logic includes:

[0119] Monitor the temperature of the white balance lamp and adjust the power supply current according to the temperature of the white balance lamp. The logic of adjusting the power supply current includes:

[0120] Determine the values ​​of the reference current, temperature threshold and temperature variation range of the white balance lamp under normal operation;

[0121] Monitor the temperature of white balance lamps;

[0122] Subtract the temperature of the white balance lamp from the temperature threshold of the white balance lamp from 1 and divide it by the value of the temperature variation range;

[0123] The current after power adjustment of the white balance lamp is obtained by combining the reference current under normal working condition.

[0124] Specifically, the function expression for regulating the power supply current is as follows:

[0125]

[0126] Wherein, I represents the current after power supply adjustment of the white balance lamp, I0 represents the reference current under normal operation, T represents the temperature of the white balance lamp, T0 represents the temperature threshold of the white balance lamp, and ΔT represents the temperature variation range.

[0127] It needs to be explained that the temperature variation range ΔT usually refers to the safe temperature range above the temperature threshold of the white balance lamp.

[0128] When the white balance lamp exceeds a safe temperature, the current of the power supply of the white balance lamp is reduced to prevent overheating, thereby extending the service life of the power supply of the white balance lamp.

[0129] The scene setting module is used to dynamically configure the scene mode and support interactive operations.

[0130] After receiving the mode switching signal from the lighting control module, the white balance lighting control system provides scene mode selection, including reading mode, movie mode, night mode, work mode and leisure mode, etc. At the same time, users can customize and create new scene modes and save them to personal settings. It provides a simple interface for users to adjust various parameters and preview the effects in real time. At the same time, it learns the user's usage habits, records the frequency and duration of use of each scene mode, analyzes the changes in user preferences in different time periods, and regularly updates the recommended scene modes based on changes in user preferences, and recommends personalized settings.
