[0002] The strip lamp is a lighting lamp composed of an LED light source, a control device, generally a power supply, a light distribution component and a shell, wherein the LED light source is composed of one or two rows of LEDs, and the effective light-emitting length is much larger than the effective light-emitting width, so as to replace the traditional lamp such as fluorescent lamp tube and neon lamp, and the LED lighting lamp is easy to install and suitable for any accessible surface.
[0003] At present, the traditional strip lamp is mostly designed as a fixed type, and the lighting direction is fixed, so it is difficult to flexibly adjust the irradiation angle according to the scene requirement, and the existing strip lamp mostly relies on manual dimming or simple ambient light sensing, without comprehensive analysis combined with the lighting requirements of different users, so the adjustment precision is low, the adaptability is poor, and it is difficult to meet the use requirement, and at the same time, the fluctuation of the ambient light is not analyzed, so the strip lamp is easily dimmed frequently, which wastes energy and reduces the lighting quality, and affects the user experience. SUMMARY
[0004] The present application relates to the field of energy-saving lighting, in particular to a three-row track type rotatable strip lamp.
[0005] To achieve the above-mentioned purpose, the present application provides a three-row track type rotatable strip lamp, which comprises a lamp holder, and further comprises: A driving power supply is slidingly arranged on the upper surface of the lamp holder, and the two sides of the lamp holder are provided with reflecting plates; A support block is fixedly connected to the lower surface of the lamp holder, two motors are symmetrically arranged on the surface of the support block, end covers are fixedly connected to the output ends of the two motors, lamp bodies two and three are respectively fixedly arranged on the surfaces of the two end covers, and a lamp body one is fixedly arranged at the bottom of the support block; The lamp body one, the lamp body two and the lamp body three all comprise a protective cover, and an illumination control system is arranged in the driving power supply.
[0006] Optionally, the illumination control system comprises an environment perception module, a false judgment prevention module, an illumination control module, an angle adjustment module, a manual control module and a preference recording module; The environment perception module is used for detecting the ambient light intensity information around the lamp body, and fusing and analyzing the ambient light intensity information and the lamp body output intensity information to obtain a comprehensive light difference D adj , and adjusting the trigger range according to the user requirement, judging whether the brightness of the lamp body one, the lamp body two and the lamp body three needs to be adjusted, and transmitting the result to the false judgment prevention module.

[0007] Optionally, the environment perception module first presets a target light intensity E tar , and then compares the ambient light intensity information and the bar lamp output intensity information with the target light intensity E tar , calculates the difference between the ambient light intensity information and the target light intensity E tar , and the difference between the bar lamp output intensity information and the target light intensity E tar , evaluates the light distance according to the difference, and finally obtains the comprehensive light distance D adj . Set the adjustment threshold of the comprehensive light distance D adj Y1, when the comprehensive light distance D adj ≥ adjustment threshold Y1, it means that the difference between the ambient light intensity information or the bar lamp output intensity information and the target light intensity E tar is large, and adjustment is needed, when the comprehensive light distance D adj < adjustment threshold Y1, then it means that the difference is small, and no adjustment is needed, and the result is transmitted to the false judgment prevention module.
[0008] Optionally, the false judgment prevention module divides a past unit time period into multiple sampling points, each sampling point corresponding to a comprehensive light distance D adj , first calculates the average of the sum of the comprehensive light distances D adj of all sampling points, obtains the average light distance D avg , and compares the comprehensive light distance D adj of each sampling point with the average light distance D avgThe fusion analysis is performed to evaluate the overall fluctuation, reflect the persistent deviation of the illumination gap, and calculate the comprehensive illumination gap D of two adjacent sampling points adj The difference of the difference is calculated to evaluate the sudden fluctuation and avoid transient interference, and finally the illumination fluctuation index F is obtained. The fluctuation threshold of the illumination fluctuation index F is set as Y2, when the illumination fluctuation index F is greater than or equal to the fluctuation threshold Y2, it indicates that the current illumination intensity has more interference factors, and the brightness adjustment is not performed; when the illumination fluctuation index F is less than the fluctuation threshold Y2, it indicates that the current illumination fluctuation is smaller and the interference factors are less, and the brightness adjustment is performed.
[0009] Optionally, when the illumination fluctuation index F is less than the fluctuation threshold Y2, it indicates that the current illumination fluctuation is smaller and the interference factors are less, and the brightness of the lamp body one, the lamp body two and the lamp body three is adjusted by the lighting control module. The lighting control module first calculates the difference between the ambient light intensity information and the target illumination intensity E tar , and the comprehensive illumination gap D adj The brightness adjustment amount ΔL is obtained by analysis, when the brightness adjustment amount ΔL is greater than 0, it indicates that the brightness of the bar-shaped lamp is increased, and when the brightness adjustment amount ΔL is less than 0, it indicates that the brightness of the bar-shaped lamp is decreased, and the brightness adjustment coefficient k is introduced to control the brightness adjustment strength to meet different user needs.
[0010] Optionally, the preference recording module triggers the condition that the user manually adjusts in a unit time after the lighting control module automatically adjusts the brightness of the bar-shaped lamp, and the brightness information of the manual adjustment is recorded to obtain the brightness manual adjustment amount ΔE sd When the brightness of the bar-shaped lamp after the user manually adjusts is greater than the brightness before the manual adjustment, the brightness adjustment coefficient k is increased to increase the adjustment strength of the lighting control module in the subsequent adjustment, and vice versa, when the brightness of the bar-shaped lamp after the user manually adjusts is less than the brightness before the manual adjustment, the brightness adjustment coefficient k is decreased to decrease the adjustment strength of the lighting control module in the subsequent adjustment.

[0012] Optionally, the manual control module includes a scene preset unit, and the scene preset unit is used to preset the lighting state of the bar-shaped lamp. The user can start the bar-shaped lamp by one key through the scene preset unit, and the brightness, angle and color temperature are automatically adjusted.
[0013] Compared with the prior art, the beneficial effects of the present application are as follows: I. This invention adjusts the trigger range according to user needs to determine whether brightness adjustment is needed for lamp body one, lamp body two, and lamp body three. It fully considers the lighting needs of different users, analyzes the different lighting requirements, improves the applicability of the strip light, ensures that the needs of different users are met, and uses an anti-false judgment module to analyze the overall illumination difference D over a past unit of time. adj The fluctuation of light intensity is analyzed, and the results are quantified to obtain the light intensity fluctuation index F. The light intensity fluctuation index F is used to determine whether to adjust the brightness. This avoids the effect of poor adjustment accuracy caused by light adjustment due to external fluctuations, prevents frequent and inaccurate brightness adjustment, achieves energy-saving effect while ensuring the lighting quality of the strip lights, and improves the user experience.
[0014] Second, this invention uses an angle adjustment module to control the start and stop of two motors. The rotation of the motor output drives the rotation of the two end caps, thereby achieving the angle deflection of lamp body two and lamp body three. The illumination angle can be flexibly adjusted, and the coverage of the strip light is wider. Furthermore, a manual control module provides manual adjustment function. Users can customize the strip light through terminal devices, including manually adjusting the brightness and color temperature of each of lamp body one, lamp body two, and lamp body three, as well as the deflection angle of lamp body two and lamp body three. The illumination mode can be flexibly adjusted according to different scenarios, improving the adaptability of this strip light.
[0015] Third, this invention uses a preference recording module to record the user's manual brightness adjustments. That is, the lighting control module records the user's manual brightness adjustments within a unit of time after the initial adjustment. This usually indicates that the adjusted lighting effect still does not meet the user's ideal state. When the user increases the brightness on the original basis, the lighting control module will increase the subsequent brightness adjustment intensity; conversely, the lighting control module will decrease the subsequent brightness adjustment intensity. This ensures that the brightness adjustment of the lighting control module meets the user's needs and guarantees the quality of automatic brightness adjustment of the strip lights.

[0018] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.
[0019] Please refer to Figures 1 to 4 The present embodiment provides a three-row track rotatable strip lamp, which comprises a lamp holder 1 and further comprises: A driving power supply 2 is slidingly arranged on the upper surface of the lamp holder 1, and the lamp holder 1 is provided with a reflecting plate 3 on both sides; The lower surface of the lamp holder 1 is fixedly connected with a supporting block 9, the surface of the supporting block 9 is symmetrically provided with two motors 7, the output ends of the two motors 7 are fixedly connected with end covers 8, the surfaces of the two end covers 8 are respectively fixedly provided with a lamp body two 5 and a lamp body three 6, and the bottom of the supporting block 9 is fixedly provided with a lamp body one 4; The lamp body one 4, the lamp body two 5 and the lamp body three 6 all comprise a protective cover, and the driving power supply 2 is provided with a lighting control system; The lighting control system comprises an environment perception module, a false judgment prevention module, a lighting control module, an angle adjustment module, a manual control module and a preference recording module; The manual control module comprises an infrared remote control module and a Bluetooth module, and a terminal device comprises a remote controller and a mobile phone. The remote controller controls the strip lamp through the infrared remote control module, and the mobile phone controls the strip lamp after pairing with the strip lamp through the Bluetooth module, so as to realize the effect of remote control. The manual control module further comprises a scene preset unit, which is used for presetting the lighting state of the strip lamp. The user sets the color temperature, brightness, angle and other information of the lamp body one 4, the lamp body two 5 and the lamp body three 6 in advance through the scene preset unit, and then starts the strip lamp. At this time, the strip lamp will automatically adjust the brightness, angle and color temperature according to the information preset by the user experience.
[0020] The environment perception module is used for detecting the ambient light intensity information of the lamp body, and fusing and analyzing the ambient light intensity information and the output intensity information of the lamp body to obtain a comprehensive light illumination difference D adj and adjusting the triggering range according to the user demand, judging whether the brightness of the lamp body one 4, the lamp body two 5 and the lamp body three 6 needs to be adjusted, and transmitting the result to the false judgment prevention module; The false judgment prevention module divides the past unit time period into a plurality of sampling points, analyzes the comprehensive light illumination difference D adj of the plurality of sampling points to obtain a light illumination fluctuation index F, and judges whether the light illumination is stable according to the light illumination fluctuation index F. When the light illumination is stable, the lighting control module is adjusted. When it is necessary to adjust the lighting brightness, the lighting control module adjusts the output power of the drive power supply 2 to change the brightness of lamp body 4, lamp body 5 and lamp body 6. By adjusting the trigger range according to user needs, it determines whether brightness adjustments are needed for lamps 1-4, 2-5, and 3-6. This analysis fully considers the lighting needs of different users, improves adjustment accuracy, ensures user satisfaction, and uses an anti-false-judgment module to analyze the overall illumination difference D over past unit time periods. adj The system analyzes the fluctuations in light intensity and quantifies the results to obtain the light fluctuation index F. This avoids adjusting the light intensity due to external fluctuations and prevents frequent and inaccurate brightness adjustments that could lead to increased energy consumption and a reduced user experience. The anti-misjudgment module can improve energy efficiency, ensure the lighting quality of the strip lights, and enhance the user experience.
[0021] The angle adjustment module is used to control the opening and closing of the two motors 7. The rotation of the output end of the motor 7 drives the two end caps 8 to rotate, thereby realizing the angle deflection of the lamp body 2 5 and the lamp body 3 6. The illumination angle can be flexibly adjusted, and the strip light covers a wider range. The motors 7 are symmetrically arranged on both sides of the support block to ensure rotational stability. It is suitable for scenarios that require local key lighting or large area uniform lighting, improving the adaptability of this strip light. The preference recording module is used to record the user's manual adjustment information of the strip light brightness after the lighting control module adjusts the brightness, and uses this as a basis to change the adjustment intensity of the subsequent lighting control module, thereby further improving the accuracy of lighting adjustment; The manual control module provides manual adjustment functionality, allowing users to customize the strip light via a terminal device. Custom adjustments include manually adjusting the brightness and color temperature of each of the three light bodies (light body 4, light body 5, and light body 6), as well as the deflection angles of light bodies 5 and 6. Simultaneously, the preference recording module adjusts the lighting control module's adjustment level based on the user's manual brightness adjustments to ensure it meets the needs of different users and further improves the adaptability of this strip light.
[0022] The environmental perception module detects the ambient light intensity information around lamp body 4, lamp body 5, and lamp body 6 using sensor devices, and analyzes it with the output brightness information of the strip lights to obtain the brightness difference. The analysis process is as follows: ; In the formula, D adj To take into account the difference in illumination; E env This refers to the ambient light intensity, specifically the ambient light brightness information surrounding lamp body 4, lamp body 5, and lamp body 6. E tarThe target light intensity is derived from user presets, representing the ideal light intensity suitable for the user. This indicates the ambient light difference, which is the difference between the current ambient light and the target light intensity. W1 is the ambient light difference influence coefficient, which is used to control the degree of influence of ambient light on the brightness adjustment of the strip light; E led Output light intensity for the strip light, i.e., the output brightness information of the strip light; This indicates the light output difference, specifically the difference between the current light intensity output by the strip light and the preset ambient light intensity. W2 is the light output difference influence coefficient, which is used to control the degree of influence of ambient light on the brightness of the strip light; The influence coefficient of ambient light difference W1 + the influence coefficient of light output difference W2 = 1; Specifically, by setting the target light intensity E tar Users can flexibly adjust the target light intensity E according to their own needs. For example, some users prefer a brighter environment and can adjust the target light intensity E. tar Set it higher, and vice versa, to ensure that it meets the needs of different users, taking into account the difference in illumination (D). adj The larger the value, the greater the difference between the current ambient light and the target light, or the more severe the deviation of the light output intensity from the target, or both. This indicates that adjustment is more necessary. Conversely, a smaller value indicates that the difference between the ambient light or light output intensity and the target light intensity E is significant. tar The smaller the difference, the better, by setting the overall illumination difference D. adj The adjustment threshold is Y1, and the value of adjustment threshold Y1 is 0.2. The adjustment threshold Y1 can also be set according to user needs. For example, in light-sensitive scenarios such as laboratories, the adjustment threshold Y1 can be reduced. When the overall light difference D adj When the threshold Y1 is greater than or equal to the target light intensity E, it indicates that the output intensity of ambient light or artificial light is greater than or equal to the target light intensity E. tar The difference is significant and needs adjustment. When the overall illumination difference D adj When the adjustment threshold Y1 is less than 1, it indicates that the difference is small and no adjustment is needed. This allows the system to determine whether adjustment is necessary based on changes in ambient light, preventing the strip lights from being too bright or too dim. This ensures the user's lighting needs are met while avoiding resource waste, achieving energy conservation and environmental protection, which aligns with the needs of green development.
[0023] Among them, when the comprehensive illumination difference D adj When the threshold Y1 is greater than or equal to the target light intensity E, it indicates that the output intensity of ambient light or artificial light is greater than or equal to the target light intensity E. tarWhen the difference is significant and adjustment is required, the anti-false alarm module performs fluctuation analysis to determine whether to initiate brightness adjustment. The anti-false alarm module is based on the comprehensive illumination difference D over a past unit of time. adj The change range is analyzed to obtain the environmental fluctuation index F. The analysis process of the anti-false judgment module is as follows: ; In the formula, F is the light fluctuation index. The larger the index, the greater the fluctuation of the light difference and the stronger the instantaneous interference. D adj,i The total illumination difference at the i-th sampling point is obtained by dividing the past unit time into multiple sampling points; D avg The average illumination difference is obtained by calculating the average of the sum of the illumination differences of all sampling points; n is the number of sampling points. For example, if the past unit of time is set to 20 seconds, and sampling is performed in seconds, then the number of sampling points is 20. β is the balance coefficient, which ranges from 0 to 1 and is used to balance the effects of long-term stability and short-term fluctuations on brightness adjustment. D adj,n The total illumination difference at the nth sampling point; D adj,n－1 The total illumination difference at the (n-1)th sampling point; Left-hand side of the formula Used to calculate the overall fluctuation of n sampling points, reflecting the persistent deviation of the illumination difference. For example, insufficient ambient light on cloudy days will lead to a comprehensive illumination difference D. adj Stable to slightly higher, right-hand side of the formula The absolute difference between adjacent sampling points is calculated to assess sudden fluctuations and avoid instantaneous interference, such as sudden light source flicker or external obstruction. A larger light fluctuation index F indicates a greater amplitude of light difference fluctuations and stronger instantaneous interference. Adjusting brightness under these conditions can easily lead to misadjustment and reduce the user experience of the strip light. Conversely, a smaller light fluctuation index F indicates more stable light difference fluctuations, allowing for more accurate brightness adjustments and improved strip light performance. The fluctuation threshold for the light fluctuation index F is set to Y2. When the light fluctuation index F ≥ the fluctuation threshold Y2, it indicates that there are many interfering factors affecting the current light intensity, and brightness adjustment is not performed. When the light fluctuation index F < the fluctuation threshold Y2, it indicates smaller light fluctuations and fewer interfering factors, and the overall light difference D is considered more stable. adj More accurate, thus the anti-misjudgment module determines whether to adjust the brightness, preventing frequent and inaccurate brightness adjustments, achieving energy-saving effects while ensuring the accuracy of brightness adjustment, and improving the performance of the strip light.
[0024] When the illumination fluctuation index F < the fluctuation threshold Y2, it indicates that the smaller the current illumination fluctuation and the fewer the interfering factors, the greater the overall illumination difference D. adj For greater accuracy, the system determines whether to adjust the brightness. The brightness of lamp body 4, lamp body 5, and lamp body 6 are then adjusted via the lighting control module. The adjustment process is as follows: ; ; E in the formula adj To adjust the output light intensity of the strip light; ΔL is the brightness adjustment amount. E env Ambient light intensity; E tar The target light intensity is derived from user presets, representing the ideal light intensity suitable for the user. sign(E tar -E env ) is a sign function, when E tar -E env When E < 0, the value is -1; when E tar -E env When the value is greater than 0, the value is 1. E led To output light intensity for the strip light; D adj To comprehensively assess the illumination difference, a comprehensive illumination difference D is introduced. adj This allows the brightness adjustment amount ΔL to adjust according to the overall illumination difference D. adj The greater the difference in illumination, the greater the range of brightness adjustment required. k is the brightness adjustment coefficient, used to control the adjustment sensitivity, with an initial value of 1; The lighting control module only applies when the light fluctuation index F output by the anti-false judgment module is less than the fluctuation threshold Y2, and the overall light difference D... adj > When the threshold Y1 is adjusted, the adjustment is initiated to avoid misadjustment caused by momentary interference, such as sudden light source flicker, and further improve the energy-saving effect. The lighting control module automatically adjusts the brightness of the strip lights, namely lamp body 4, lamp body 5 and lamp body 6, according to the actual external environment, without the need for manual adjustment, thus improving the user's comfort. When the angle adjustment module adjusts the illumination angle of the strip light, causing a change in the ambient light, the strip light can also be identified by the environmental sensing module and automatically adjust its brightness to maintain the set lighting environment. This ensures that the changes in ambient light after angle adjustment are captured in real time and accurately matched to the brightness through the lighting control module.
[0025] Furthermore, the preference recording module records user manual adjustments after the lighting control module has been activated. If a user manually adjusts the brightness within a unit of time after the lighting control module has been activated, it usually indicates that the adjusted lighting effect still does not meet the user's ideal state. To ensure the automatic brightness adjustment effect of this three-row track-type rotatable strip light, it needs to follow the user's adjustments and change the adjustment intensity, that is, adjust the brightness adjustment coefficient k to change the brightness adjustment intensity of the lighting control module. The initial value of the brightness adjustment coefficient k is set to 1, and it changes with subsequent manual adjustments by the user. ; Where k is the brightness adjustment coefficient; E adj To adjust the output light intensity of the strip light; ΔE sd This is the manual brightness adjustment amount. If it is increased from the original value, then ΔE sd If the value is positive, and it is reduced from the original value, then ΔE sd It is a negative number; To manually adjust the output light intensity of the strip light; When the user increases the brightness from the original level, k is greater than 1, and the lighting control module will increase the subsequent brightness adjustment. Conversely, when the user decreases the brightness from the original level, k is less than 1, and the lighting control module will decrease the subsequent brightness adjustment. This ensures that the brightness adjustment of the lighting control module matches the user's actual experience and is not just adjusted based on brightness information, thus guaranteeing the effectiveness of the strip lights.
