[0002] With the continuous development of wireless communication and lighting technology, LED (Light-Emitting Diode) luminous antenna, as a new type of equipment combining wireless communication function and lighting function, has shown great application potential in the fields of smart city, smart home, etc. There is a kind of luminous antenna whose light-emitting diode draws power from the metal wire body, and the metal wire body only generates microcurrent when working as an antenna, which cannot provide enough power. At the same time, the metal wire body is in the shape of an oblong strip, and it is also difficult to cross more light-emitting diodes on it, resulting in low overall luminous brightness. In addition, the light-emitting diodes are cross-arranged on the metal wire body, which is also easy to affect the performance of the metal wire body as an antenna to send radio waves. Therefore, a LED luminous antenna structure with high luminous brightness and less impact on antenna performance has emerged. It is necessary to perform performance testing after the LED luminous antenna is produced. The existing performance testing methods of LED luminous antennas often involve many aspects, but in the specific testing process, the test results may be inaccurate due to the influence of environmental factors, etc., and it is difficult to accurately evaluate its performance in different environments. Therefore, a more accurate performance testing method is needed.

[0034] The embodiments of the present application solve the problem in the prior art that it is difficult to accurately perform performance testing of LED light-emitting antennas by providing a performance testing method and an LED light-emitting antenna for an LED light-emitting antenna. The method analyzes whether to perform a power performance test adjustment based on power performance test data, obtains brightness test data corresponding to a brightness test of the LED light-emitting antenna after the power performance test adjustment is qualified, analyzes whether to perform a brightness test adjustment based on the brightness test data, and obtains radio transmission test data corresponding to a radio transmission test of the LED light-emitting antenna after the brightness test adjustment is qualified, thereby analyzing whether to perform a radio transmission test adjustment based on the radio transmission test data, thereby achieving accurate performance testing of the LED light-emitting antenna.

[0035] The technical solution in the embodiment of the present application is to solve the above-mentioned problem of difficulty in accurately performing performance detection of LED light-emitting antennas. The overall idea is as follows:

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

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

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

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

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

[0041] An electrical performance test is performed within a preset first time period, and the antenna voltage and antenna resistance corresponding to the LED light-emitting antenna obtained in each electrical performance test are obtained through a multimeter. The maximum antenna voltage, the minimum antenna voltage, and the maximum antenna resistance are obtained through statistical analysis. The specific process is to arrange the antenna voltage and the antenna resistance in descending order, and take the first and last antenna voltages as the maximum antenna voltage and the minimum antenna voltage, respectively, and take the first antenna resistance as the maximum antenna resistance.

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

[0043] Furthermore, the specific acquisition process of the power performance influence degree index is as follows: the result of the ratio operation of the minimum antenna voltage and the minimum antenna voltage standard is processed to obtain the minimum voltage compliance coefficient (i.e., UMIN in the specific restriction expression of the power performance influence degree index); the result of the ratio operation of the sum of the maximum antenna voltage and the maximum antenna voltage standard and twice the maximum antenna voltage standard is processed to obtain the maximum voltage compliance coefficient (i.e., UMAX in the specific restriction expression of the power performance influence degree index); the result of the ratio operation of the maximum antenna resistance and the maximum antenna resistance standard is processed to obtain the maximum resistance compliance coefficient (i.e., RMIN in the specific restriction expression of the power performance influence degree index); when the minimum antenna voltage is not less than the minimum antenna voltage standard, the power performance influence degree index is obtained according to 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 limiting expression of the power performance impact index is:

[0045]

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

[0047] In this embodiment, when the minimum value of the antenna voltage is less than the standard minimum value of the 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 are respectively represented by the weight ratios of the preset antenna voltage minimum value, antenna voltage maximum value and antenna resistance maximum value obtained from the database in the power performance impact index, and respectively represent the impact degree on the power performance impact index. The antenna voltage minimum value, antenna voltage maximum value and antenna resistance maximum value are respectively mapped to the weight ratios corresponding to the antenna voltage minimum value, antenna voltage maximum value and antenna resistance maximum value preset in the database to form a mapping set, wherein the mapping relationship can be one-to-one or many-to-one, and the currently used antenna voltage minimum value, antenna voltage maximum value and antenna resistance maximum value are respectively input into the corresponding mapping set to obtain the first weight factor, the second weight factor and the third weight factor.

[0049] The temperature of the preset first time period for the power performance test is obtained using a temperature sensor, and the temperature influence factor corresponding to the preset temperature is obtained from the database according to the temperature, indicating the influence degree of the temperature on the power performance influence degree index. The temperature and the temperature influence factor corresponding to the preset temperature in the database form a mapping set, in which 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 value of the antenna voltage is greater than or equal to the standard minimum value of the antenna voltage, it indicates that the antenna can still work stably under low voltage conditions, which helps to reduce the performance fluctuation of the LED light-emitting antenna under low voltage environment. The forward voltage of the LED light-emitting antenna will decrease with the increase of temperature, because with the increase of temperature, the electric field strength inside the LED weakens, and the required external electric field energy decreases. The reflection in the external forward voltage is the decrease of the forward conduction voltage. If the contact at the connection is poor, it may cause the voltage signal to produce a voltage drop during the transmission process, making the measured voltage value lower. When the maximum value of the antenna voltage is larger, the power performance test may be affected by temperature or poor contact at the connection. The resistance value of the antenna reflects the loss when it transmits electric energy. If there is poor contact at the connection, it may cause the contact resistance to increase, making the measured resistance value larger. Therefore, when the maximum value of the antenna resistance is larger, the power performance test may be affected by poor contact at the connection. When the maximum value of the antenna voltage and the minimum value of the antenna voltage become larger, the maximum value of the antenna resistance may increase to keep the current of the LED light-emitting antenna stable.

[0051] like Figure 2 As shown, it is a curve diagram of the power performance impact index provided in the embodiment of the present application, with the minimum voltage compliance coefficient as the independent variable and the power performance impact 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 antenna voltage standard minimum value is 2.5V, and the antenna voltage minimum value is greater than or equal to the antenna voltage standard minimum value. Through the increase and decrease analysis of curve one, curve two and curve three, it can be seen that when the minimum voltage compliance coefficient is larger, the power performance impact index is larger; when the minimum voltage compliance coefficient is smaller, the power performance impact index is smaller. The statistical table of relevant data of the power performance impact index is shown in Table 1:

[0052] Table 1 Statistics of relevant data on power performance impact indicators

[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 impact indexes of Curve 1, Curve 2 and Curve 3 are 1.66, 1.71 and 1.77 respectively. It can be seen that the greater the minimum voltage compliance coefficient, the maximum voltage compliance coefficient and the maximum resistance compliance coefficient, the greater the power performance impact index, and the more power performance test adjustment is needed. When the power performance test adjustment is required according to the power performance impact index, the power performance test adjustment is carried out in time to avoid long-term testing of the LED light-emitting antenna in an inappropriate environment.

[0055] Furthermore, the specific process of analyzing whether to make adjustments to the power performance test 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 made; when the power performance impact degree index is not less than the power performance impact threshold, a power performance test adjustment is made, and the power performance test adjustment includes temperature adjustment and power test connection adjustment.

[0056] In this embodiment, when the minimum value of the antenna voltage is greater than or equal to the standard minimum value of the antenna voltage, correspondingly, when the minimum value of the antenna voltage is smaller, the minimum voltage compliance coefficient is larger, correspondingly, when the maximum value of the antenna voltage is larger, the maximum voltage compliance coefficient is larger, correspondingly, when the maximum value of the antenna resistance is larger, the maximum resistance compliance coefficient is larger, correspondingly, when the minimum voltage compliance coefficient, the maximum voltage compliance coefficient, and the maximum resistance compliance coefficient are larger, the power performance impact index is larger, and the power performance test adjustment is more needed, otherwise the power performance test adjustment is not needed, and when the power performance impact index is less than the power performance impact threshold, the power performance test adjustment is stopped. By more accurately analyzing whether to perform the power performance test adjustment based on the minimum value of the antenna voltage, the maximum value of the antenna voltage, and the maximum value of the antenna resistance, more accurate power performance test adjustment is achieved, and the accuracy of the power performance test is improved.

[0057] Temperature adjustment refers to lowering the temperature step by step (0.5°C each time) to observe whether the maximum value of the antenna resistance is less than the standard maximum value of the antenna resistance. When the condition is met, stop the temperature adjustment.

[0058] The power test connection adjustment refers to adjusting the connection method of the LED light-emitting antenna for power performance testing, 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] Furthermore, the brightness test data includes: minimum value of antenna luminous efficiency, minimum value of antenna light intensity, minimum value of antenna luminous flux, reference minimum value of antenna luminous efficiency, reference minimum value of antenna light intensity and reference minimum value of antenna luminous flux; a brightness test is performed in a preset second time period to obtain the luminous efficiency, light intensity and luminous flux obtained in each brightness test, and the minimum value of antenna luminous efficiency, minimum value of antenna light intensity and minimum value of antenna luminous flux are obtained through statistical analysis; the minimum value of antenna luminous efficiency represents the minimum luminous efficiency obtained by the LED light-emitting antenna during the brightness test; the minimum value of antenna light intensity represents the minimum light intensity obtained by the LED light-emitting antenna during the brightness test; the minimum value of antenna luminous flux represents the minimum luminous flux obtained by the LED light-emitting antenna during the brightness test; the brightness test data is used to analyze and obtain brightness test influencing indicators; the brightness test influencing indicators are used to reflect the degree of influence on the LED light-emitting antenna when performing a qualified brightness test.

[0060] In this embodiment, the antenna luminous efficiency refers to the minimum value, which represents the minimum luminous efficiency obtained by the LED light-emitting antenna when performing a qualified brightness test; the antenna light intensity refers to the minimum value, which represents the minimum light intensity obtained by the LED light-emitting antenna when performing a qualified brightness test; the antenna luminous flux refers to the minimum value, which represents the minimum luminous flux obtained by the LED light-emitting antenna when performing a qualified brightness test.

[0061] During the brightness test, the luminous efficiency of the LED light-emitting antenna is obtained by the integrating sphere method or the spectrophotometer method, the light intensity of the LED light-emitting antenna is obtained by the light intensity meter or the photometer, and the luminous flux of the LED light-emitting antenna is obtained by the integrating sphere method or the spectrophotometer method. The luminous efficiency, light intensity and luminous flux are arranged in descending order, and the luminous efficiency, light intensity and luminous flux at the last place 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 light flux. The luminous efficiency, light intensity and luminous flux obtained by the LED light-emitting antenna through the qualified brightness test are obtained from the database and arranged in descending order, and the luminous efficiency, light intensity and luminous flux at the last place 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 light flux.

[0062] Furthermore, the method for obtaining the brightness test influence index is as follows: the result of the ratio operation of the sum of the minimum value of the antenna luminous efficiency and the reference minimum value of the antenna luminous efficiency and twice the reference minimum value of the antenna luminous efficiency is processed to obtain the luminous efficiency matching coefficient (i.e., GFMIN in the restriction expression of the brightness test influence index); the minimum value of the antenna light intensity and the minimum value of the antenna light intensity reference are processed to obtain the light intensity matching coefficient (i.e., GTMIN in the restriction expression of the brightness test influence index); the result of the ratio operation of the minimum value of the antenna luminous flux and the minimum value of the antenna luminous flux reference is processed to obtain the luminous flux matching coefficient (i.e., GUMIN in the restriction expression of the brightness test influence index); the brightness test influence index is obtained according to the luminous efficiency matching coefficient, the light intensity matching coefficient, the luminous flux matching coefficient, the humidity influence factor, the fourth weight factor, the fifth weight factor and the sixth weight factor.

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

[0068] The humidity of the preset second time period for the brightness test is obtained using a humidity sensor, and the humidity influence factor of the preset humidity is obtained from the database according to the humidity, indicating the influence degree of humidity on the brightness test influence index. The humidity and the humidity influence factor corresponding to the preset humidity in the database form a mapping set, wherein the mapping relationship can be one-to-one or many-to-one, and 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 by the weight proportions of the preset antenna luminous efficiency minimum value, antenna light intensity minimum value and antenna luminous flux minimum value obtained from the database in the brightness test influencing index, respectively representing the degree of influence on the brightness test influencing index. The antenna luminous efficiency minimum value, antenna light intensity minimum value and antenna luminous flux minimum value are respectively mapped to the weight proportions corresponding to the antenna luminous efficiency minimum value, antenna light intensity minimum value and antenna luminous flux minimum value preset in the database to form a mapping set, wherein the mapping relationship can be one-to-one or many-to-one, and the currently used antenna luminous efficiency minimum value, antenna light intensity minimum value and antenna luminous flux minimum value are respectively input into the corresponding mapping set to obtain the fourth weight factor, the fifth weight factor and the sixth weight factor.

[0070] The specific process of analyzing whether to perform brightness test adjustment is as follows: compare the obtained brightness test impact index with the preset brightness test impact threshold obtained from the database. When the brightness test impact index is less than the brightness test impact threshold, no brightness test adjustment is performed; when the brightness test impact index is not less than the brightness test impact threshold, a brightness test adjustment is performed, and the brightness test adjustment includes humidity adjustment and brightness test connection adjustment. When the brightness test impact index is less than the brightness test impact threshold, the brightness test adjustment is ended.

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

[0072] The specific method of brightness test connection adjustment is to debug the connection method of the LED light-emitting antenna for brightness test, analyze whether the minimum value of antenna light intensity is greater than the reference minimum value of antenna light intensity and whether the minimum value of antenna luminous flux is greater than the reference minimum value of antenna luminous flux, and stop brightness test connection adjustment when both conditions are met.

[0073] In a high humidity environment, the LED packaging material may absorb moisture, causing changes in the 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 needed. By analyzing whether to adjust the brightness test from three aspects: 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 effect of more accurately determining whether to adjust the brightness test 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 order from large to small, and the signal strength, modulation depth and signal-to-noise ratio at the last place are respectively used as the minimum antenna signal strength, the minimum antenna signal modulation depth and the minimum antenna signal-to-noise ratio.

[0076] The standard minimum signal strength value indicates the minimum signal strength of the LED light-emitting antenna when performing a qualified radio transmission test; the standard minimum modulation depth value indicates the minimum modulation depth of the LED light-emitting antenna when performing a qualified radio transmission test; the standard minimum signal-to-noise ratio value indicates the minimum signal-to-noise ratio of the LED light-emitting antenna when performing a qualified radio transmission test.

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

[0078] Furthermore, the method for obtaining the radio transmission impact index is as follows: the result of the ratio operation between the minimum antenna signal strength and the minimum standard signal strength is processed to obtain the signal strength compliance coefficient (XQMIN in the specific restriction expression of the radio transmission impact index); the result of the ratio operation between the minimum antenna signal modulation depth and the minimum standard modulation depth is processed to obtain the modulation depth compliance coefficient (XSMIN in the specific restriction expression of the radio transmission impact index); the result of the ratio operation between the minimum antenna signal signal-to-noise ratio and the minimum standard signal-to-noise ratio is processed to obtain the signal-to-noise ratio compliance coefficient (XDMIN in the specific restriction expression of the radio transmission impact index); when the minimum antenna signal strength is greater than the minimum standard signal strength, the radio transmission impact index is obtained according to the signal strength compliance coefficient, the modulation depth compliance coefficient, the signal-to-noise ratio compliance coefficient, the temperature influence coefficient, the humidity influence coefficient, the seventh weight factor, the eighth weight factor and the 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 to analyze whether to perform radio transmission test adjustment, and provide feedback reminders to the preset personnel.

[0080] The specific limiting expression of the radio transmission impact index is:

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

[0082]

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

[0084] The temperature and humidity of the preset third time period for the radio transmission test are obtained using a temperature sensor and a humidity sensor. The temperature influence coefficient and humidity influence coefficient corresponding to the preset temperature and humidity are obtained from the database according to the temperature and humidity, respectively, indicating the degree of influence of the temperature and humidity on the radio transmission index. The temperature and humidity are respectively mapped with the temperature influence coefficient and humidity influence coefficient corresponding to the preset temperature and humidity in the database to form a mapping set, wherein the mapping relationship can be one-to-one or many-to-one. The current temperature and humidity are respectively input into the corresponding mapping set to obtain the temperature influence coefficient and humidity influence coefficient corresponding to the temperature and humidity. The value range of the temperature influence coefficient and the humidity influence coefficient is (0, 1).

[0085] The seventh weight factor, the eighth weight factor and the ninth weight factor are respectively represented by the weight proportions of the preset antenna signal strength minimum value, the antenna signal modulation depth minimum value and the antenna signal signal-to-noise ratio minimum value obtained from the database in the radio transmission impact index, respectively representing the degree of influence on the radio transmission impact index. The antenna signal strength minimum value, the antenna signal modulation depth minimum value and the antenna signal signal-to-noise ratio minimum value are respectively mapped to the weight proportions corresponding to the antenna signal strength minimum value, the antenna signal modulation depth minimum value and the antenna signal signal-to-noise ratio minimum value preset in the database to form a mapping set, wherein the mapping relationship can be one-to-one or many-to-one, and the currently used antenna signal strength minimum value, antenna signal modulation depth minimum value and antenna signal-to-noise ratio minimum value are respectively input into the corresponding mapping set to obtain the seventh weight factor, the eighth weight factor and the ninth weight factor.

[0086] High temperature may cause the performance of the electronic components of the LED light antenna to decline, which in turn affects the quality of the radio signal and reduces the strength of the radio signal. The increase in temperature may cause the luminous efficiency of the LED to decrease, thereby reducing the modulation depth of the signal. When the temperature increases and causes the LED luminous intensity to decrease, the modulation depth may also decrease. The temperature increase may also increase the thermal noise inside the device, which will interfere with the reception and decoding of wireless signals. Therefore, when the temperature rises, the signal-to-noise ratio (i.e., the ratio of signal power to noise power) may decrease. The reduction in the signal-to-noise ratio means that the signal's anti-interference ability is weakened and the modulation quality is reduced.

[0087] Increased humidity may cause the luminous efficiency of LED antennas to decrease, because the infiltration of water vapor may affect the working state of the LED light-emitting diode. The reduction in luminous efficiency will affect the modulation depth of the signal, because the modulation depth is related to the amplitude change of the signal. Therefore, when the humidity increases, the modulation depth may decrease. Increased humidity may also increase the noise level inside the device. This noise may come from the interaction between water vapor and electronic components or the condensation of water vapor inside the device. The increase in noise will interfere with the reception and decoding of wireless signals, thereby reducing the signal-to-noise ratio (that is, the ratio of signal power to noise power). The reduction in the signal-to-noise ratio means that the signal's anti-interference ability is weakened and the modulation quality is reduced.

[0088] Electromagnetic interference can interfere with the useful signal sent by the LED light antenna, making it difficult for the receiving end to accurately detect and demodulate the signal. This will cause the modulation depth of the signal to decrease, 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, affecting the transmission quality and reliability of the signal. Electromagnetic interference is a major source of noise, which will increase the noise level inside the device. The increase in noise will interfere with the reception and decoding of wireless signals, thereby reducing the signal-to-noise ratio (that is, the ratio of signal power to noise power). The reduction in the signal-to-noise ratio means that the signal's anti-interference ability is weakened and the modulation quality is reduced. In the case of severe electromagnetic interference, the signal-to-noise ratio may be significantly reduced, resulting in the signal cannot be correctly received and decoded.

[0089] When the minimum antenna signal strength is greater than the minimum standard signal strength, the smaller the minimum antenna signal strength will result in a smaller signal strength compliance coefficient, the smaller the corresponding minimum antenna signal modulation depth will result in a smaller modulation depth compliance coefficient, the smaller the corresponding minimum antenna signal signal-to-noise ratio will result in a smaller signal-to-noise ratio compliance coefficient, and the smaller the corresponding signal strength compliance coefficient, modulation depth compliance coefficient, and signal-to-noise ratio compliance coefficient, the greater the radio transmission impact index, and the more radio transmission test adjustment is needed, and vice versa. Whether to perform radio transmission test adjustment is analyzed from three aspects: the minimum antenna signal strength, the minimum antenna signal modulation depth, and the minimum antenna signal signal-to-noise ratio, so as to achieve more accurate radio transmission test adjustment.

[0090] When the LED light-emitting antenna is undergoing a power performance test, the power performance test adjustment is performed promptly and accurately to avoid the LED light-emitting antenna being in an inappropriate environment and connection state, thereby reducing the hardware performance changes of the LED light-emitting antenna caused by the inappropriate environment and connection state. Then, when the LED light-emitting antenna is undergoing a brightness test, the brightness test adjustment is performed promptly and accurately to further reduce the hardware performance changes of the LED light-emitting antenna. Then, when the LED light-emitting antenna is undergoing a radio transmission test, it is possible to more accurately analyze whether to perform a radio transmission test adjustment, thereby avoiding erroneous adjustments due to hardware performance changes of the LED light-emitting antenna, thereby allowing the above tests to be performed more accurately.

[0091] The specific process of analyzing whether to perform radio transmission test adjustment 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, no radio transmission test adjustment is performed; when the radio transmission impact index is not less than the radio transmission impact threshold, radio transmission test adjustment is performed. The radio transmission test adjustment includes temperature adjustment, humidity adjustment and electromagnetic interference adjustment. When the radio transmission impact index is less than the radio transmission impact threshold, the radio transmission test adjustment is ended.

[0092] Temperature adjustment refers to lowering the temperature step by step (such as lowering it by 0.5°C each time) and observing whether the minimum modulation depth of the antenna signal is greater than the minimum modulation depth of the standard. When the condition is met, stop the temperature adjustment.

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

The feeding point 21 of the antenna element 2 is located on the circuit board 1 below the center line of the antenna element 2.

[0096] A plurality of LED lamp beads 3 are arranged on the circuit board 1 along the edge of the front projection of the antenna vibrator 2. The LED lamp beads 3 are divided into two groups, one of which is arranged on the front of the circuit board 1, and the other is arranged on the back of the circuit board 1. From the front projection, the two groups of LED lamp beads 3 are arranged along the edge of the antenna vibrator 2, which can reduce the impact on the antenna performance of the antenna vibrator 2, and at the same time, there is sufficient arrangement space along the edge of the antenna vibrator 2.

[0097] The connecting wires between the above-mentioned LED lamp beads 3 are arranged on the back 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, which is used for external equipment to independently power and control the LED lamp beads 3. Separating the power connections of the antenna vibrator 2 and the LED lamp beads 3 can avoid mutual influence between the two. Furthermore, the LED lamp beads 3 use LED lamp beads with driver chips, which is convenient for realizing the diversity of light effects, and can also reduce the use of surrounding components, and the ratio of the specification width of the LED lamp beads 3 to the width of the antenna vibrator 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 impact on the antenna performance.

The two groups of LED lamp beads 3 are located on opposite sides, which can facilitate the arrangement of the LED lamp beads 3.

The edge profile of the lower part of the antenna vibrator 2 where the feeding point 21 is located is Y-shaped and gradient. This gradient structure can effectively avoid the influence of the routing of the connecting wires of the LED lamp beads 3 on the antenna performance. Furthermore, the connecting wires of the LED lamp beads 3 located on the back of the antenna vibrator 2 are routed along the edge of the circuit board 1, so that coupling is generated between the antenna vibrators 2, which optimizes the impedance and increases the bandwidth at the same time.

[0102] like Figure 3 , Figure 4 and Figure 5The LED light-emitting antenna device shown includes a connecting base 4 and a diffusion tube 5, wherein the diffusion tube 5 is fixedly connected to the connecting base 4, and the connecting base 4 is also provided with an antenna coaxial line 41 and a connecting wire head 42.
