[0001] The present invention relates to the technical field of antenna detection, and particularly to a performance detection method for an LED light-emitting antenna and an LED light-emitting antenna. Background Art

[0002] With the continuous development of wireless communication and lighting technologies, an LED (Light-Emitting Diode) light-emitting antenna, as a new device that combines wireless communication and lighting functions, shows great application potential in fields such as smart cities and smart homes. For one type of light-emitting antenna, the light-emitting diodes draw power from a metal wire body. When the metal wire body operates as an antenna, it only generates a micro current and cannot provide sufficient power. At the same time, the metal wire body is in a long oval shape, and it is difficult to span a large number of light-emitting diodes thereon, resulting in low overall light-emitting brightness. In addition, when the light-emitting diodes are spanned on the metal wire body, it is also easy to affect the performance of the metal wire body as an antenna for transmitting radio waves. Therefore, an LED light-emitting antenna structure with high light-emitting brightness and less impact on antenna performance has emerged, and performance detection is required after the production of this LED light-emitting antenna. Existing performance detection methods for LED light-emitting antennas often involve many aspects, but in the specific detection process, the detection results may be inaccurate due to the influence of environmental factors and other reasons, making it difficult to accurately evaluate its performance in different environments. Therefore, a more accurate performance detection method is needed.

[0003] The existing performance detection system for LED light-emitting antennas performs performance detection by placing the LED light-emitting antenna in different performance detection devices, and clarifies the performance of the LED light-emitting antenna according to the results of the performance detection, so as to achieve the performance detection of the LED light-emitting antenna.

[0005] For example, an antenna state detection circuit and an electronic device disclosed in a patent application with the publication number CN115629335A include: a gating circuit, a switching circuit, and a voltage dividing circuit; the antenna under test is electrically connected to the gating circuit, the switching circuit, and the voltage dividing circuit in sequence; one end of the switching circuit forms a first detection node with the gating circuit; one end of the voltage dividing circuit is connected to a first DC power supply, and the other end is electrically connected to the other end of the switching circuit to form a second detection node; when the antenna under test is short-circuited, the voltage difference between the first DC power supply and the first detection node is less than a preset value, causing the switching circuit to cut off, and the second detection node to be at a high level.

[0035] The technical solution in the embodiment of the present application for solving the problem of difficult accurate performance detection of the LED light-emitting antenna is generally as follows:

[0036] By obtaining the power performance test data corresponding to the power performance test of the LED light-emitting antenna, obtaining the power performance impact degree index based on the power performance test data, and analyzing whether to adjust the power performance test; after the power performance test adjustment is qualified, obtaining the brightness test data corresponding to the brightness test of the LED light-emitting antenna, obtaining the brightness test impact index based on the brightness test data, and analyzing whether to adjust the brightness test; after the brightness test adjustment is qualified, obtaining the radio transmission test data corresponding to the radio transmission test of the LED light-emitting antenna, obtaining the radio transmission impact index based on the radio transmission test data, and analyzing whether to adjust the radio transmission test, the effect of accurately detecting the performance of the LED light-emitting antenna is achieved.

[0037] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0038] As Figure 1 shown, it is a flowchart of a performance detection method for an LED light-emitting antenna provided by an embodiment of the present application. The method includes the following steps: obtaining the power performance test data corresponding to the power performance test of the LED light-emitting antenna, and analyzing whether to adjust the power performance test based on the power performance test data; after the power performance test adjustment is qualified, obtaining the brightness test data corresponding to the brightness test of the LED light-emitting antenna, and analyzing whether to adjust the brightness test based on the brightness test data; after the brightness test adjustment is qualified, obtaining the radio transmission test data corresponding to the radio transmission test of the LED light-emitting antenna, and analyzing whether to adjust the radio transmission test based on the radio transmission test data.

[0039] Among them, the power performance test data includes: the minimum antenna voltage, the maximum antenna voltage, the maximum antenna resistance, the standard minimum antenna voltage, the standard maximum antenna voltage, and the standard maximum antenna resistance; the minimum antenna voltage represents the minimum voltage obtained by the LED light-emitting antenna during the power performance test; the maximum antenna voltage represents the maximum voltage obtained by the LED light-emitting antenna during the power performance test; the maximum antenna resistance represents the maximum resistance obtained by the LED light-emitting antenna during the power performance test; the power performance test data is used to analyze and obtain the power performance impact degree index; the power performance impact degree index is used to reflect the impact degree of the LED light-emitting antenna during the power performance test.

[0040] In this embodiment, the standard minimum antenna voltage represents the minimum voltage obtained by the LED light-emitting antenna during a qualified power performance test; the standard maximum antenna voltage represents the maximum voltage obtained by the LED light-emitting antenna during a qualified power performance test; the standard maximum antenna resistance represents the maximum resistance obtained by the LED light-emitting antenna during a qualified power performance test.

[0041] During a preset first time period, a power performance test is conducted. The antenna voltage and antenna resistance corresponding to the LED light-emitting antenna obtained from each power performance test are acquired through a multimeter. The maximum antenna voltage, minimum antenna voltage, and maximum antenna resistance are obtained through statistical analysis. The specific process is as follows: The antenna voltage and antenna resistance are respectively arranged in descending order. The antenna voltage ranked first and the last are respectively used as the maximum antenna voltage and the minimum antenna voltage, and the antenna resistance ranked first is used as the maximum antenna resistance.

[0042] The antenna voltage and antenna resistance obtained when the LED light-emitting antenna conducts a qualified power performance test are acquired from the database. The antenna voltage and antenna resistance are respectively arranged in descending order. The antenna voltage ranked first and the last are respectively used as the standard maximum antenna voltage and the standard minimum antenna voltage, and the antenna resistance ranked first is used as the maximum antenna resistance.

[0043] Furthermore, the specific process for obtaining the power performance influence degree index is as follows: The result of the ratio operation between the minimum antenna voltage and the standard minimum antenna voltage is processed to obtain the minimum voltage compliance coefficient (i.e., UMIN in the specific limit expression of the power performance influence degree index); the result of the ratio operation between the sum of the maximum antenna voltage and the standard maximum antenna voltage and twice the standard maximum antenna voltage is processed to obtain the maximum voltage compliance coefficient (i.e., UMAX in the specific limit expression of the power performance influence degree index); the result of the ratio operation between the maximum antenna resistance and the standard maximum antenna resistance is processed to obtain the maximum resistance compliance coefficient (i.e., RMIN in the specific limit expression of the power performance influence degree index); when the minimum antenna voltage is not less than the standard minimum antenna voltage, the power performance influence degree index is obtained based on the minimum voltage compliance coefficient, the maximum voltage compliance coefficient, the maximum resistance compliance coefficient, the temperature influence factor, the first weight factor, the second weight factor, and the third weight factor.

[0044] Specifically, the specific limit expression of the power performance influence degree index is:

[0045]

[0046] Where α represents the index of the influence degree on the electrical performance of the LED light-emitting antenna, UMIN represents the minimum voltage compliance coefficient, UMAX represents the maximum voltage compliance coefficient, RMIN represents the maximum resistance compliance coefficient, QS represents the minimum antenna voltage of the LED light-emitting antenna in the electrical performance test, QE represents the maximum antenna voltage of the LED light-emitting antenna in the electrical performance test, QT represents the maximum antenna resistance of the LED light-emitting antenna in the electrical performance test, WS represents the standard minimum antenna voltage of the LED light-emitting antenna in the qualified electrical performance test, WE represents the standard maximum antenna voltage of the LED light-emitting antenna in the qualified electrical performance test, WT represents the standard maximum antenna resistance of the LED light-emitting antenna in the qualified electrical performance test, a represents the temperature influence factor, f1 represents the first weight factor, f2 represents the second weight factor, and f3 represents the third weight factor.

[0047] In this embodiment, when the minimum antenna voltage is less than the standard minimum antenna voltage, it indicates that the power performance test of the LED light-emitting antenna is inaccurate, and at this time, feedback reminder is given to the preset personnel.

[0048] The first weight factor, the second weight factor, and the third weight factor respectively represent the weight proportions occupied in the electrical performance influence degree index corresponding to the preset minimum antenna voltage, maximum antenna voltage, and maximum antenna resistance obtained from the database, and respectively represent the influence degrees on the electrical performance influence degree index. The minimum antenna voltage, maximum antenna voltage, and maximum antenna resistance are respectively formed into a mapping set with the weight proportions corresponding to the preset minimum antenna voltage, maximum antenna voltage, and maximum antenna resistance in the database, where the mapping relationship can be one-to-one or many-to-one. The currently used minimum antenna voltage, maximum antenna voltage, and maximum antenna resistance are respectively input into the corresponding mapping set to obtain the first weight factor, the second weight factor, and the third weight factor.

[0049] Use a temperature sensor to obtain the temperature in the preset first time period for the electrical performance test. The temperature influence factor corresponding to the preset temperature obtained from the database according to the temperature represents the influence degree of the temperature on the electrical performance influence degree index. The temperature and the temperature influence factor corresponding to the preset temperature in the database are formed into a mapping set, where the mapping relationship can be one-to-one or many-to-one. The current temperature is input into the corresponding mapping set to obtain the temperature influence factor corresponding to the temperature, and the value range of the temperature influence factor is (0, 1).

[0050] When the minimum antenna voltage is greater than or equal to the standard minimum antenna voltage, it indicates that the antenna can still operate stably under low voltage conditions, which helps to reduce the performance fluctuations of the LED lighting antenna in a low voltage environment. The forward voltage of the LED lighting antenna decreases with the increase in temperature. Because as the temperature rises, the electric field strength inside the LED weakens, and the required external electric field energy decreases. Reflected in the applied forward voltage, it is the decrease in the forward conduction voltage. If the connection is poor, it may cause a voltage drop during the transmission of the voltage signal, resulting in a lower measured voltage value. When the maximum antenna voltage is larger, the power performance test may be affected by temperature or poor connection at the joint. The resistance value of the antenna reflects the power loss during its power transmission. If there is a poor connection at the joint, it may lead to an increase in the contact resistance, resulting in a larger measured resistance value. Therefore, when the maximum antenna resistance is larger, the power performance test may be affected by poor connection at the joint. When the maximum antenna voltage and the minimum antenna voltage increase, it may cause an increase in the maximum antenna resistance to maintain the current stability of the LED lighting antenna.

[0051] As Figure 2 shown, it is the curve graph of the power performance influence degree index provided by the embodiment of the present application, with the minimum voltage compliance coefficient as the independent variable and the power performance influence degree index as the dependent variable. The first weight factor, the second weight factor, and the third weight factor are 0.3, 0.4, and 0.3 respectively. The preset standard minimum antenna voltage is 2.5V, and the minimum antenna voltage is greater than or equal to the standard minimum antenna voltage. By analyzing the increase and decrease of Curve 1, Curve 2, and Curve 3, it can be seen that when the minimum voltage compliance coefficient is larger, the power performance influence degree index is larger; when the minimum voltage compliance coefficient is smaller, the power performance influence degree index is smaller. The statistical table of relevant data of the power performance influence degree index is shown in Table 1:

[0052] Table 1 Statistical Table of Relevant Data of Power Performance Influence Degree Index

[0053]

[0054] When the minimum voltage compliance coefficients of Curve 1, Curve 2, and Curve 3 are 1, 1.1, and 1.2 respectively, and other parameters are as shown in the above table, the power performance influence degree indexes of Curve 1, Curve 2, and Curve 3 are 1.66, 1.71, and 1.77 respectively. It can be seen that when the minimum voltage compliance coefficient, the maximum voltage compliance coefficient, and the maximum resistance compliance coefficient are larger, the power performance influence degree index is larger, and the more power performance test adjustments are needed. When it is analyzed from the power performance influence degree index that power performance test adjustments are needed, make power performance test adjustments in a timely manner to avoid long-term testing of the LED lighting antenna in an inappropriate environment.

[0055] Further, the specific process of analyzing whether to perform power performance test adjustment is as follows: Compare the obtained power performance impact degree index with the power performance impact threshold obtained from the database. When the power performance impact degree index is less than the power performance impact threshold, no power performance test adjustment is performed. When the power performance impact degree index is not less than the power performance impact threshold, power performance test adjustment is performed, and the power performance test adjustment includes temperature adjustment and power test connection adjustment.

[0056] In this embodiment, when the minimum antenna voltage is greater than or equal to the standard minimum antenna voltage, correspondingly, the smaller the minimum antenna voltage is, the larger the minimum voltage compliance coefficient is. Correspondingly, the larger the maximum antenna voltage is, the larger the maximum voltage compliance coefficient is. Correspondingly, the larger the maximum antenna resistance is, the larger the maximum resistance compliance coefficient is. Correspondingly, when the minimum voltage compliance coefficient, the maximum voltage compliance coefficient, and the maximum resistance compliance coefficient are larger, the power performance impact degree index is larger, and power performance test adjustment is more needed. On the contrary, no power performance test adjustment is needed. When the power performance impact degree index is less than the power performance impact threshold, stop the power performance test adjustment. By more accurately analyzing whether to perform power performance test adjustment from the minimum antenna voltage, the maximum antenna voltage, and the maximum antenna resistance, more accurate power performance test adjustment is achieved, and the accuracy of the power performance test is improved.

[0057] Temperature adjustment means gradually reducing the temperature (each time by 0.5 °C) and observing whether the maximum antenna resistance is less than the standard maximum antenna resistance. When the condition is met, stop the temperature adjustment.

[0058] Power test connection adjustment means adjusting the connection method of the LED-emitting antenna for power performance testing and observing whether the maximum antenna resistance is less than the standard maximum antenna resistance and whether the maximum antenna voltage is less than the standard maximum antenna voltage. When the maximum antenna resistance is less than the standard maximum antenna resistance and the maximum antenna voltage is less than the standard maximum antenna voltage, stop the power test connection adjustment.

[0059] Further, the brightness test data includes: the minimum value of the antenna luminous efficiency, the minimum value of the antenna light intensity, the minimum value of the antenna luminous flux, the reference minimum value of the antenna luminous efficiency, the reference minimum value of the antenna light intensity, and the reference minimum value of the antenna luminous flux; the brightness test is performed in a preset second time period, and the luminous efficiency, light intensity, and luminous flux obtained from each brightness test are acquired. The minimum value of the antenna luminous efficiency, the minimum value of the antenna light intensity, and the minimum value of the antenna luminous flux are obtained through statistical analysis; the minimum value of the antenna luminous efficiency represents the minimum luminous efficiency obtained by the LED luminous antenna during the brightness test; the minimum value of the antenna light intensity represents the minimum light intensity obtained by the LED luminous antenna during the brightness test; the minimum value of the antenna luminous flux represents the minimum luminous flux obtained by the LED luminous antenna during the brightness test; the brightness test data is used to analyze and obtain the brightness test influence index; the brightness test influence index is used to reflect the influence degree suffered by the LED luminous antenna during the qualified brightness test.

[0060] In this embodiment, the reference minimum value of the antenna luminous efficiency represents the minimum luminous efficiency obtained by the LED luminous antenna during the qualified brightness test; the reference minimum value of the antenna light intensity represents the minimum light intensity obtained by the LED luminous antenna during the qualified brightness test; the reference minimum value of the antenna luminous flux represents the minimum luminous flux obtained by the LED luminous antenna during the qualified brightness test.

[0061] During the brightness test, the luminous efficiency of the LED luminous antenna is obtained by the integrating sphere method or the spectrophotometer method, the light intensity of the LED luminous antenna is obtained by the illuminometer or the photometer, and the luminous flux of the LED luminous antenna is obtained by the integrating sphere method or the spectro-photometer method. The luminous efficiency, light intensity, and luminous flux are respectively arranged in descending order. The luminous efficiency, light intensity, and luminous flux ranked last are respectively used as the minimum value of the antenna luminous efficiency, the minimum value of the antenna light intensity, and the minimum value of the antenna luminous flux. The luminous efficiency, light intensity, and luminous flux obtained by the LED luminous antenna through the qualified brightness test are retrieved from the database and respectively arranged in descending order. The luminous efficiency, light intensity, and luminous flux ranked last are respectively used as the reference minimum value of the antenna luminous efficiency, the reference minimum value of the antenna light intensity, and the reference minimum value of the antenna luminous flux.

[0062] Further, the method for obtaining the influencing index of brightness test is as follows: Process the result of the ratio operation of the sum of the minimum antenna luminous efficiency and the reference minimum antenna luminous efficiency to twice the reference minimum antenna luminous efficiency to obtain the luminous efficiency fitting coefficient (i.e., GFMIN in the limiting expression of the influencing index of brightness test); Process the minimum antenna luminous intensity and the reference minimum antenna luminous intensity to obtain the luminous intensity fitting coefficient (i.e., GTMIN in the limiting expression of the influencing index of brightness test); Process the result of the ratio operation of the minimum antenna luminous flux and the reference minimum antenna luminous flux to obtain the luminous flux fitting coefficient (i.e., GUMIN in the limiting expression of the influencing index of brightness test); Obtain the influencing index of brightness test according to the luminous efficiency fitting coefficient, the luminous intensity fitting coefficient, the luminous flux fitting coefficient, the humidity influencing factor, the fourth weight factor, the fifth weight factor, and the sixth weight factor.

[0063] In this embodiment, the limiting expression of the influencing index of brightness test is:

[0064] θ = b * coth(GFMIN * h1 + GTMIN * h2 + GUMIN * h3);

[0067] In the formula, θ represents the influencing index of brightness test of the LED luminous antenna, GFMIN represents the luminous efficiency fitting coefficient, GTMIN represents the luminous intensity fitting coefficient, GUMIN represents the luminous flux fitting coefficient, GF represents the minimum antenna luminous efficiency of the LED luminous antenna in the brightness test, GT represents the minimum antenna luminous intensity of the LED luminous antenna in the brightness test, GU represents the minimum antenna luminous flux of the LED luminous antenna in the brightness test, RF represents the reference minimum antenna luminous efficiency of the LED luminous antenna in the qualified brightness test, RT represents the reference minimum antenna luminous intensity of the LED luminous antenna in the qualified brightness test, RU represents the reference minimum antenna luminous flux of the LED luminous antenna in the qualified brightness test, h1 represents the fourth weight factor, h2 represents the fifth weight factor, h3 represents the sixth weight factor, and b represents the humidity influencing factor.

[0068] The humidity sensor is used to obtain the humidity during a preset second time period for the brightness test. The humidity influence factor corresponding to the preset humidity obtained from the database represents the degree of influence of humidity on the brightness test influence index. A mapping set is formed by pairing the humidity with the humidity influence factor corresponding to the preset humidity in the database, where the mapping relationship can be one-to-one or many-to-one. The current humidity is input into the corresponding mapping set to obtain the humidity influence factor corresponding to the humidity, and the value range of the humidity influence factor is (0, 1).

[0069] The fourth weight factor, the fifth weight factor, and the sixth weight factor are respectively represented as the weight ratios in the brightness test influence index corresponding to the minimum antenna luminous efficiency, the minimum antenna light intensity, and the minimum antenna luminous flux preset and obtained from the database, respectively representing the degree of influence on the brightness test influence index. A mapping set is formed by pairing the minimum antenna luminous efficiency, the minimum antenna light intensity, and the minimum antenna luminous flux with the weight ratios corresponding to the minimum antenna luminous efficiency, the minimum antenna light intensity, and the minimum antenna luminous flux preset in the database, where the mapping relationship can be one-to-one or many-to-one. The currently used minimum antenna luminous efficiency, minimum antenna light intensity, and minimum antenna luminous flux are respectively input into the corresponding mapping sets to obtain the fourth weight factor, the fifth weight factor, and the sixth weight factor.

[0070] The specific process of analyzing whether to adjust the brightness test is as follows: Compare the obtained brightness test influence index with the preset brightness test influence threshold obtained from the database. When the brightness test influence index is less than the brightness test influence threshold, no adjustment is made to the brightness test; when the brightness test influence index is not less than the brightness test influence threshold, an adjustment to the brightness test is made, which includes humidity adjustment and brightness test connection adjustment. When the brightness test influence index is less than the brightness test influence threshold, the brightness test adjustment ends.

[0071] The specific method of humidity adjustment is to gradually reduce the humidity (such as reducing by 1% each time), and analyze whether the minimum antenna luminous efficiency is greater than the reference minimum antenna luminous efficiency. When the condition is met, the humidity adjustment stops.

[0072] The specific method of brightness test connection adjustment is to debug the connection method during the brightness test of the LED luminous antenna, and analyze whether the minimum antenna light intensity is greater than the reference minimum antenna light intensity and whether the minimum antenna luminous flux is greater than the reference minimum antenna luminous flux. When both conditions are met, the brightness test connection adjustment stops.

[0073] In a high humidity environment, the LED packaging material may absorb moisture, causing changes in internal stress of the package or material degradation. These changes may affect the luminous performance of the LED, resulting in a decrease in light intensity. A high humidity environment may also cause a decrease in the luminous efficiency of the LED, which in turn leads to a decrease in luminous flux. Therefore, when the minimum value of the antenna luminous efficiency is smaller, the luminous efficiency matching coefficient is smaller. Correspondingly, when the minimum value of the antenna light intensity is smaller, the light intensity matching coefficient is smaller. Correspondingly, when the minimum value of the antenna luminous flux is smaller, the luminous flux matching coefficient is smaller. Correspondingly, when the luminous efficiency matching coefficient is smaller, the light intensity matching coefficient is smaller, and the luminous flux matching coefficient is smaller, the brightness test impact index is greater, and the brightness test adjustment is more necessary. By analyzing whether to perform brightness test adjustment based on the three aspects of the minimum value of the antenna luminous efficiency, the minimum value of the antenna light intensity, and the minimum value of the antenna luminous flux, a more accurate determination of whether to perform brightness test adjustment is achieved.

[0074] Furthermore, the radio transmission test data includes: minimum antenna signal strength, minimum antenna signal modulation depth, minimum antenna signal signal-to-noise ratio, minimum standard signal strength, minimum standard modulation depth and minimum standard signal-to-noise ratio; performing a radio transmission test within a preset third time period, obtaining the signal strength, modulation depth and signal-to-noise ratio of the antenna signal during each radio transmission test, and obtaining the minimum antenna signal strength, minimum antenna signal modulation depth and minimum antenna signal-to-noise ratio through statistical analysis; the minimum antenna signal strength indicates the minimum signal strength of the LED light-emitting antenna during the radio transmission test; the minimum antenna signal modulation depth indicates the minimum signal modulation depth of the LED light-emitting antenna during the radio transmission test; the minimum antenna signal signal-to-noise ratio indicates the minimum signal-to-noise ratio of the LED light-emitting antenna during the radio transmission test; the radio transmission test data is used to analyze and obtain radio transmission impact indicators; the radio transmission impact indicators are used to reflect the degree of impact on the LED light-emitting antenna during the radio transmission test.

[0075] In this embodiment, during the radio transmission test, the signal strength of the radio wave of the LED light-emitting antenna is obtained by a signal strength meter, the modulation depth of the radio wave of the LED light-emitting antenna is obtained by a modulation depth meter, and the power values of the signal and noise of the radio wave of the LED light-emitting antenna are measured by a signal analyzer to perform a ratio operation. The ratio operation result is the signal-to-noise ratio. The signal strength, modulation depth and signal-to-noise ratio are arranged in descending order, and the signal strength, modulation depth and signal-to-noise ratio at the last place are respectively used as the minimum value of the antenna signal strength, the minimum value of the antenna signal modulation depth and the minimum value of the antenna signal-to-noise ratio.

[0076] The minimum standard signal strength represents the minimum signal strength of the LED light-emitting antenna during the qualified radio transmission test; the minimum standard modulation depth represents the minimum modulation depth of the LED light-emitting antenna during the qualified radio transmission test; the minimum standard signal-to-noise ratio represents the minimum signal-to-noise ratio of the LED light-emitting antenna during the qualified radio transmission test.

[0077] The signal strength, modulation depth, and signal-to-noise ratio obtained from the qualified radio transmission test of the LED light-emitting antenna in the database are sorted in descending order, and the signal strength, modulation depth, and signal-to-noise ratio ranked last are used as the minimum standard signal strength, minimum standard modulation depth, and minimum standard signal-to-noise ratio, respectively.

[0078] Furthermore, the method for obtaining the radio transmission influence index is as follows: Process the result of the ratio operation between the minimum antenna signal strength and the minimum standard signal strength to obtain the signal strength compliance coefficient (XQMIN in the specific limit expression of the radio transmission influence index); Process the result of the ratio operation between the minimum antenna signal modulation depth and the minimum standard modulation depth to obtain the modulation depth compliance coefficient (XSMIN in the specific limit expression of the radio transmission influence index); Process the result of the ratio operation between the minimum antenna signal-to-noise ratio and the minimum standard signal-to-noise ratio to obtain the signal-to-noise ratio compliance coefficient (XDMIN in the specific limit expression of the radio transmission influence index); When the minimum antenna signal strength is greater than the minimum standard signal strength, obtain the radio transmission influence index based on the signal strength compliance coefficient, modulation depth compliance coefficient, signal-to-noise ratio compliance coefficient, temperature influence coefficient, humidity influence coefficient, seventh weight factor, eighth weight factor, and ninth weight factor.

[0079] In this embodiment, when the minimum antenna signal strength is less than or equal to the minimum standard signal strength, the reliability of the radio transmission test data is low, and it is not suitable for analyzing whether to adjust the radio transmission test, so a feedback reminder is sent to the preset personnel.

[0080] The specific limit expression of the radio transmission influence index is:

[0081] δ = w * n * sech(XQMIN * k1 + XSMIN * k2 + k3 * XDMIN), XQ > AQ;

[0082]

[0083] In the formula, δ represents the radio transmission impact index of the LED light-emitting antenna, XQMIN represents the signal strength compliance coefficient, XSMIN represents the modulation depth compliance coefficient, XDMIN represents the signal-to-noise ratio compliance coefficient, XQ represents the minimum value of the antenna signal strength of the LED light-emitting antenna in the radio transmission test, XS represents the minimum value of the antenna signal modulation depth of the LED light-emitting antenna in the radio transmission test, XD represents the minimum value of the antenna signal-to-noise ratio of the LED light-emitting antenna in the radio transmission test, AQ represents the minimum value of the standard signal strength in the qualified radio transmission test of the LED light-emitting antenna, AS represents the minimum value of the standard modulation depth in the qualified radio transmission test of the LED light-emitting antenna, AD represents the minimum value of the standard signal-to-noise ratio in the qualified radio transmission test of the LED light-emitting antenna, k1 represents the seventh weight factor, k2 represents the eighth weight factor, k3 represents the ninth weight factor, w represents the temperature impact coefficient, n represents the humidity impact coefficient, and e represents the natural constant.

[0084] Use a temperature sensor and a humidity sensor to obtain the temperature and humidity during a preset third time period for the radio transmission test. Obtain the temperature impact coefficient and humidity impact coefficient corresponding to the preset temperature and humidity respectively from the database according to the temperature and humidity, which respectively represent the influence degrees of temperature and humidity on the radio transmission impact index. Form a mapping set for the temperature and humidity with the temperature impact coefficient and humidity impact coefficient corresponding to the preset temperature and humidity in the database respectively. The mapping relationship therein can be a one-to-one or many-to-one relationship. Input the current temperature and humidity into the corresponding mapping sets respectively to obtain the temperature impact coefficient and humidity impact coefficient corresponding to the temperature and humidity. The value ranges of the temperature impact coefficient and humidity impact coefficient are both (0, 1).

[0085] The seventh weight factor, the eighth weight factor, and the ninth weight factor respectively represent the weight ratios occupied in the radio transmission impact index corresponding to the preset minimum values of the antenna signal strength, the minimum value of the antenna signal modulation depth, and the minimum value of the antenna signal-to-noise ratio obtained from the database, which respectively represent the influence degrees on the radio transmission impact index. Form a mapping set for the minimum value of the antenna signal strength, the minimum value of the antenna signal modulation depth, and the minimum value of the antenna signal-to-noise ratio with the weight ratios corresponding to the preset minimum values of the antenna signal strength, the minimum value of the antenna signal modulation depth, and the minimum value of the antenna signal-to-noise ratio in the database respectively. The mapping relationship therein can be a one-to-one or many-to-one relationship. Input the currently used minimum value of the antenna signal strength, the minimum value of the antenna signal modulation depth, and the minimum value of the antenna signal-to-noise ratio into the corresponding mapping sets respectively to obtain the seventh weight factor, the eighth weight factor, and the ninth weight factor.

[0086] High temperatures may cause a decline in the performance of the electronic components of the LED light-emitting antenna, which in turn affects the quality of radio signals, resulting in a decrease in radio signal strength. An increase in temperature may also lead to a reduction in the luminous efficiency of the LED, thereby decreasing the modulation depth of the signal. When the increase in temperature causes a decrease in the luminous intensity of the LED, the modulation depth may also decrease. Additionally, an increase in temperature may increase the thermal noise within the device, and this thermal noise will interfere with the reception and decoding of wireless signals. Therefore, in the case of rising temperatures, the signal-to-noise ratio (i.e., the ratio of signal power to noise power) may decrease. A decrease in the signal-to-noise ratio means a weakened anti-interference ability of the signal and a decline in modulation quality.

[0087] An increase in humidity may cause a reduction in the luminous efficiency of the LED light-emitting antenna because the infiltration of water vapor may affect the operating state of the light-emitting diodes of the LED. The decrease in luminous efficiency affects the modulation depth of the signal because the modulation depth is related to the amplitude change of the signal. Therefore, in the case of increasing humidity, the modulation depth may decrease. An increase in humidity may also increase the noise level within the device, and this noise may come from the interaction between water vapor and electronic components or the condensation of water vapor within the device, etc. The increase in noise interferes with the reception and decoding of wireless signals, thereby reducing the signal-to-noise ratio (i.e., the ratio of signal power to noise power). A decrease in the signal-to-noise ratio means a weakened anti-interference ability of the signal and a decline in modulation quality.

[0088] Electromagnetic interference will interfere with the useful signals transmitted by the LED light-emitting antenna, making it difficult for the receiving end to accurately detect and demodulate the signals. This will cause a decrease in the modulation depth of the signal because the modulation depth is related to the amplitude change of the signal. In the case of severe electromagnetic interference, the modulation depth may be significantly reduced, thus affecting the transmission quality and reliability of the signal. Electromagnetic interference is a major source of noise, and it will increase the noise level within the device. The increase in noise interferes with the reception and decoding of wireless signals, thereby reducing the signal-to-noise ratio (i.e., the ratio of signal power to noise power). A decrease in the signal-to-noise ratio means a weakened anti-interference ability of the signal and a decline in modulation quality. In the case of severe electromagnetic interference, the signal-to-noise ratio may be significantly reduced, resulting in the signal being unable to be correctly received and decoded.

[0089] When the minimum value of the antenna signal strength is greater than the minimum value of the standard signal strength, the smaller the minimum value of the antenna signal strength, the smaller the signal strength compliance coefficient. Correspondingly, the smaller the minimum value of the antenna signal modulation depth, the smaller the modulation depth compliance coefficient. Correspondingly, the smaller the minimum value of the antenna signal signal-to-noise ratio, the smaller the signal-to-noise ratio compliance coefficient. When the signal strength compliance coefficient, the modulation depth compliance coefficient, and the signal-to-noise ratio compliance coefficient are smaller, the greater the impact index of radio transmission, and the more radio transmission test adjustments are required. Conversely, fewer radio transmission test adjustments are required. Analyzing whether to perform radio transmission test adjustments from the three aspects of the minimum value of the antenna signal strength, the minimum value of the antenna signal modulation depth, and the minimum value of the antenna signal signal-to-noise ratio enables more accurate radio transmission test adjustments to be made.

[0090] When conducting power performance tests on the LED lighting antenna, make timely and accurate power performance test adjustments to avoid the LED lighting antenna being in an inappropriate environment and connection state, and reduce the change in the hardware performance of the LED lighting antenna caused by the inappropriate environment and connection state. Then, when conducting brightness tests on the LED lighting antenna, make timely and accurate brightness test adjustments to further reduce the change in the hardware performance of the LED lighting antenna. Then, when conducting radio transmission tests on the LED lighting antenna, it is possible to more accurately analyze whether to perform radio transmission test adjustments, avoiding incorrect adjustments due to changes in the hardware performance of the LED lighting antenna, enabling the above tests to be conducted more accurately.

[0091] The specific process of analyzing whether to perform radio transmission test adjustments is as follows: Compare the obtained radio transmission impact index with the radio transmission impact threshold obtained from the database. When the radio transmission impact index is less than the radio transmission impact threshold, do not perform radio transmission test adjustments; when the radio transmission impact index is not less than the radio transmission impact threshold, perform radio transmission test adjustments. Radio transmission test adjustments include temperature adjustment, humidity adjustment, and electromagnetic interference adjustment. When the radio transmission impact index is less than the radio transmission impact threshold, end the radio transmission test adjustments.

[0092] Temperature adjustment means gradually reducing the temperature (e.g., reducing by 0.5 °C each time), and observing whether the minimum value of the antenna signal modulation depth is greater than the minimum value of the standard modulation depth. Stop temperature adjustment when the condition is met.

[0093] Humidity adjustment means gradually reducing the humidity (e.g., reducing by 1% each time), and observing whether the minimum value of the antenna signal modulation depth is greater than the minimum value of the standard modulation depth. Stop humidity adjustment when the condition is met. Electromagnetic interference adjustment means gradually increasing the intensity of electromagnetic shielding and observing whether the minimum value of the antenna signal strength is greater than the minimum value of the standard signal strength. Stop electromagnetic interference adjustment when the condition is met.

[0094] An LED light-emitting antenna provided in this embodiment applies a performance detection method for an LED light-emitting antenna, and is characterized by comprising: a circuit board, an antenna element, and a plurality of LED lamp beads. The antenna element is in a flat plate shape and is laid on the front surface of the circuit board. The feeding point of the antenna element is located on the circuit board below the midline of the antenna element. The plurality of LED lamp beads are arranged on the circuit board along the edge of the front projection of the antenna element. The connecting wires between the plurality of LED lamp beads are arranged on the back surface of the circuit board, and a lamp bead control connection point for power supply and control of the LED lamp beads by an external device is provided on the circuit board.

[0095] The LED light-emitting antenna comprises a circuit board 1, an antenna element 2, and a plurality of LED lamp beads 3. The circuit board 1 is a PCB board or an FPC board and serves as a base material for carrying the antenna element 2 and the LED lamp beads 3. The antenna element 2 is in a flat plate shape and is laid on the front surface of the circuit board 1. The feeding point 21 of the antenna element 2 is located on the circuit board 1 below the midline of the antenna element 2.

[0096] The plurality of LED lamp beads 3 are arranged on the circuit board 1 along the edge of the front projection of the antenna element 2. These LED lamp beads 3 are divided into two groups. One group is arranged on the front surface of the circuit board 1, and the other group is arranged on the back surface of the circuit board 1. From the front projection, these two groups of LED lamp beads 3 are arranged along the edge of the antenna element 2, which can reduce the influence on the antenna performance of the antenna element 2. At the same time, there is a relatively sufficient arrangement space along the edge of the antenna element 2.

[0097] The connecting wires between the above-mentioned LED lamp beads 3 are arranged on the back surface of the circuit board 1, and a lamp bead control connection point 11 is reserved on the circuit board 1, including a power connection point and a control signal connection point, for separately supplying power and controlling the LED lamp beads 3 by an external device. Separating the power connection of the antenna element 2 and the LED lamp beads 3 can avoid mutual influence between the two. Further, the LED lamp beads 3 are selected as LED lamp beads with a driving chip, which is convenient to achieve light effect diversity, and at the same time, the use of surrounding components can be reduced. And the ratio of the specification width of the LED lamp beads 3 to the width of the antenna element 2 is not greater than 1 / 5, so that the specification width of the LED lamp beads 3 will not be too large, thereby reducing the influence on the antenna performance.

[0098] In one embodiment, as Figure 3 shown, it is a partial cross-sectional three-dimensional structure schematic diagram of the antenna device of the LED light-emitting antenna provided by the embodiment of the present application. As Figure 4 shown, it is provided by the embodiment of the present application Figure 3An enlarged schematic diagram at position B. A group of LED lamp beads 3 are arranged on the front side of the circuit board 1 and concentrated on the left side of the circuit board 1, while a group of LED lamp beads 3 on the front side of the circuit board 1 are concentrated on the right side of the circuit board 1. Of course, the LED lamp beads 3 on the front side can also be arranged on the right side of the circuit board 1, and the LED lamp beads 3 on the back side can be arranged on the left side of the circuit board 1. The two groups of LED lamp beads 3 are located on the opposite sides, which facilitates the arrangement of the LED lamp beads 3.

[0099] In one embodiment, each group of LED lamp beads 3 is divided into two sub-groups. As Figure 5 shown, it is a three-dimensional structure and a partial enlarged schematic diagram of the LED light-emitting antenna provided by the embodiment of the present application after removing the diffusion tube. The LED lamp beads 3 on the front side of the circuit board 1 are divided into two sub-groups and are respectively arranged on the left and right sides of the front side of the circuit board 1; the LED lamp beads 3 on the back side of the circuit board 1 are also divided into two sub-groups and are respectively arranged on the left and right sides of the back side of the circuit board 1. This arrangement method of the LED lamp beads 3 can arrange a larger number, and at the same time, there are LED lamp beads 3 on both the left and right sides, making the light emission more uniform.

[0100] In one embodiment, the circuit board 1 is selected as a rectangular long strip structure, and the antenna element 2 covers the front side of the upper part of the circuit board 1. In this structure, a reserved hollow mounting position 22 is provided on the antenna element 2 for mounting the LED lamp beads 3. As Figure 6 shown, it is a front view schematic diagram of the antenna element of the LED light-emitting antenna provided by the embodiment of the present application. If only one group of LED lamp beads 3 is arranged on the left side, then the antenna element 2 only has a reserved hollow mounting position 22 on the left side. If there is a group of LED lamp beads 3 on both sides, then the antenna element 2 has reserved hollow mounting positions 22 on both the left and right sides.

[0101] As Figure 7 shown, it is a front view schematic diagram of the LED light-emitting antenna structure provided by the embodiment of the present application. As Figure 8 shown, it is provided by the embodiment of the present application Figure 7 An enlarged schematic diagram at position A. The antenna element 2 is arranged on the upper part of the circuit board 1. The feeding point 21 of the antenna element 2 is below the midline. The edge contour shape of the lower part of the antenna element 2 where the feeding point 21 is located is gradually changed in a Y shape. This gradually changing structure can effectively avoid the influence of the wiring of the connection wires of the LED lamp beads 3 on the antenna performance. Further, the connection wires of the LED lamp beads 3 on the back side of the antenna element 2 are routed along the edge of the circuit board 1, causing coupling between the antenna elements 2, optimizing the impedance and increasing the bandwidth at the same time.

[0102] As Figure 3 、 Figure 4 and Figure 5The shown LED light-emitting antenna device includes a connection base 4 and a diffusion tube 5. The diffusion tube 5 is fixedly connected to the connection base 4. The connection base 4 is further provided with an antenna coaxial line 41 and a connection terminal 42. The antenna uses the light-emitting antenna with the above-mentioned LED light-emitting antenna structure. The light-emitting antenna is placed inside the diffusion tube 5. The end of the antenna coaxial line 41 is electrically connected to the feeding point 21, and signals are transmitted to the antenna oscillator 2 through the antenna coaxial line 41. The antenna coaxial line 41 is arranged at the middle line position of the circuit board 1 to avoid blocking the light emission of the LED lamp beads 3. The connection terminal 42 is electrically connected to the lamp bead control connection point 11. After the connection base 4 is connected to an external device, the LED lamp beads 3 can be powered and controlled through the connection terminal 42.

[0103] Preferred embodiments, such as Figure 3 and Figure 4 , the diffusion tube 5 includes an inner diffusion tube 51 and an outer diffusion tube 52. The light-emitting antenna is placed inside the inner diffusion tube 51. By using a double-layer diffusion tube 5, the light emitted by the LED lamp beads 3 is more uniform, and the lighting effect is better.
