The first embodiment is as follows:

referring to fig. 1, fig. 1 shows a schematic flow of a lamp bead light parameter calibration method provided in an embodiment of the present application, where the method is applied to a lamp, and the lamp is provided with a lamp bead, which is detailed as follows:

and 101, acquiring current batch information, current loss degree and current power error of the lamp beads.

The parameters of the outgoing lamp beads of the lamp beads in different batches are different, the parameters of the outgoing lamp beads are different, and the parameters of the lamp beads after light parameter calibration are also different. Therefore, batch information of the lamp beads needs to be considered when the target lamp bead parameters are obtained. In an alternative embodiment, the current batch information of the lamp beads includes, but is not limited to, the production batch number of the lamp beads.

The loss degree of the lamp beads can influence the light parameters of the lamp beads, and the light parameters of the lamp beads include but are not limited to hue (color), saturation, color temperature and brightness of the lamp beads; for example, if the color temperature is 1, the loss degree of the lamp bead affects the color temperature, and the change of the color temperature of the lamp bead affects the result of the synthetic light, for example, it is assumed that the color temperature is 2500K for warm white light and 6500K for cold white light: 1, the color temperature of the lamp beads after light combination is 4500K. When the loss degree is increased, the color temperature of the warm white light is changed from 2500K to 2600K, and the color temperature is also changed according to the following formula 1: 1, the light combination result is 4550K, and the color temperature of the lamp bead has deviation at the moment. Therefore, the loss degree of the lamp beads needs to be considered when the target lamp bead parameters are obtained.

Loss degree can characterize the loss condition of lamp pearl during the lamps and lanterns use, under the general condition, the loss of lamp pearl can be along with the use of lamps and lanterns constantly increases, accumulates the loss degree that obtains the lamp pearl to the output brightness value of lamp pearl in this application, in an optional embodiment, acquires the current loss degree of lamp pearl, include: acquiring an output brightness value ratio of the lamp beads in the current time period, wherein the output brightness value ratio is the ratio of the output brightness value of the lamp beads to the maximum brightness value; updating the historical loss degree of the lamp beads according to the proportion of the output brightness value to obtain the current loss degree; the historical wear level is a wear level acquired before the start time of the current period. The historical loss degree of the lamp bead is updated according to the output brightness value ratio to obtain the current loss degree, and specifically, the output brightness value ratio is added to the historical loss degree of the lamp bead to obtain the current loss degree. For example, if the output luminance value ratio is 0.5 and the historical wear level is 1000, the current wear level is 1000.5.

Optionally, the output brightness ratio may be a ratio of an output brightness value of a lamp bead at a certain moment in the current time period to a maximum brightness value, or may also be a ratio of a mean value of output brightness values of lamp beads at multiple moments in the current time period to the maximum brightness value, which is not limited herein. It should be noted that, the loss degree of the lamp bead when leaving the factory can be set to 0, and the loss degree can be accumulated along with the continuous use of the lamp. The current loss degree is calculated according to the method, and the loss condition of the lamp bead can be obtained according to the service condition of the lamp bead, namely the longer the service life of the lamp bead is, the larger the output brightness value in the service life is, the larger the loss brought to the lamp bead by the service of the lamp bead is, and the more serious the loss degree of the corresponding lamp bead is.

When batch information and loss degree of the lamp beads are not changed, if errors of actual power corresponding to the brightness value of the lamp beads and factory power corresponding to the brightness value are different, optical parameters of the lamp beads are also different, therefore, the power errors of the lamp beads are also an important factor influencing the optical parameters of the lamp beads, the power errors of the lamp beads need to be considered when target lamp bead parameters are obtained, and the power errors refer to errors between the actual power corresponding to the brightness value of the lamp beads and the factory power corresponding to the brightness value of the lamp beads.

In an alternative embodiment, obtaining the current power error comprises: acquiring actual power corresponding to the current brightness value of the lamp bead; calculating the difference value of the actual power and the factory power corresponding to the current brightness value; and calculating the ratio of the difference value to the factory power corresponding to the current brightness value to obtain the current power error. It should be noted that the current power error may be a negative number.

Optionally, a voltage and a current corresponding to the current brightness value of the lamp bead are obtained, and the actual power is calculated according to the voltage and the current.

Optionally, the difference absolute value between the actual power and the factory power corresponding to the current brightness value may also be obtained, and the ratio between the difference absolute value and the factory power corresponding to the current brightness value is calculated to obtain the current power error. For example: and the actual power corresponding to the current brightness value of the lamp bead is 90w, and the factory power corresponding to the current brightness value is 100w, so that |90-100|/100 is the current power error. The reason for calculating the absolute difference value is that the actual power corresponding to the current brightness value of the lamp bead may be higher or lower than the factory power corresponding to the current brightness value, so that the absolute difference value between the actual power and the factory power corresponding to the current brightness value is obtained.

It should be noted that a storage medium for storing the current batch information and the factory power corresponding to different luminance values is provided in the lamp, and the storage medium includes, but is not limited to, a storage chip, a Near Field Communication (NFC) chip, and other media capable of storing information.

102, acquiring target lamp bead parameters corresponding to preset batch information, preset loss degree information and preset power error information; the preset batch information is the same batch information as the current batch information, the preset loss degree information is the loss degree information matched with the current loss degree, and the preset power error information is the power error information matched with the current power error.

The target lamp bead parameters can be lamp bead parameters matched with current batch information, current loss degree and current power errors, the current lamp bead parameters are actual lamp bead parameters of the current lamp beads, the target lamp bead parameters are lamp bead parameters subjected to light parameter calibration, and after the current lamp bead parameters of the lamp beads are updated to the target lamp bead parameters, the light parameters of the lamp beads can be calibrated. The lamp bead parameters include, but are not limited to, color coordinates, spectrum, and other parameters related to the light parameter of the lamp bead.

By way of example and not limitation, the target lamp bead parameters may be obtained through the following two embodiments.

In one embodiment, obtaining target lamp bead parameters corresponding to preset batch information, preset loss degree information, and preset power error information includes: sending current batch information, current loss degree and current power error to a server, wherein the current batch information, the current loss degree and the current power error are used for searching target lamp bead parameters corresponding to preset batch information, preset loss degree information and preset power error information; and receiving target lamp bead parameters from the server.

In another embodiment, at least one first update package is stored in the lamp, where the first update package includes mapping relationships between corresponding batch information, loss degree, power error and lamp bead parameters, and after the lamp acquires current batch information, current loss degree and current power error of a lamp bead, the lamp may search for a target lamp bead parameter in the first update package according to the current batch information, current loss degree and current power error, specifically, the target lamp bead parameter corresponding to preset batch information, preset loss degree information and preset power error information is acquired, including: searching a target update package from at least one first update package according to the current batch information, the current loss degree, the current power error and the batch information, the loss degree information and the power error information corresponding to the first update package, wherein the batch information corresponding to the target update package is preset batch information, the loss degree information corresponding to the target update package is preset loss degree information, and the power error information corresponding to the target update package is preset power error information; and determining the lamp bead parameters in the target update package as target lamp bead parameters. Wherein the first update package may be stored in a storage medium of the luminaire.

Optionally, the batch information corresponding to the first update package may be batch information in the first update package.

In an alternative embodiment, the wear-out level information corresponding to the first update packet may be a wear-out level in the first update packet, and the corresponding power error information may be a power error in the first update packet. In this case, the preset loss degree information is a loss degree that is the same as the current loss degree, and the preset power error information is a power error that is the same as the current power error.

In another alternative embodiment, the wear-level information corresponding to the first update packet may be a wear-level interval, and the corresponding power error information may be a power error interval. In this case, the preset loss degree information is a loss degree interval including the current loss degree, and the preset power error information is a power error interval including the current power error.

Wherein, obtain loss degree interval and power error interval, include:

acquiring a first threshold sequence and a second threshold sequence, wherein the first threshold sequence comprises at least one loss degree threshold, and the second threshold sequence comprises at least one power error threshold; it should be noted that the first threshold sequence and the second threshold sequence may be stored in the luminaire and/or the server.

Determining the loss degree in the target update package as the minimum value of the loss degree interval, and determining the minimum value in at least one candidate loss degree as the maximum value of the loss degree interval, wherein the candidate loss degree refers to the loss degree in the loss degree set, which is greater than the loss degree in the target update package; the set of wear-out levels comprises wear-out levels within all candidate update packets and a wear-out level threshold in a first threshold sequence; the candidate updating package is a first updating package with the same batch information as that in the target updating package;

determining the power error in the target update package as the minimum value of the power error interval, and determining the minimum value of at least one candidate power error as the maximum value of the power error interval, wherein the candidate power error is a power error in the power error set which is larger than the power error in the target update package; the set of power errors includes power errors within all candidate update packets and power error thresholds in the second threshold sequence. In an optional embodiment, under the condition that the target lamp bead parameter is not obtained, a user is reminded to calibrate the light parameter of the lamp bead based on a preset light parameter calibration mode. Optionally, under the condition that the target lamp bead parameter is not obtained, the user may be notified that the target lamp bead parameter is not found, and be reminded to calibrate the light parameter of the lamp bead based on a preset light parameter calibration mode.

Since the loss degree and the power error can be used for judging whether the light parameter deviation occurs in the lamp bead, in order to perform light parameter calibration on the lamp bead in time when the light parameter deviation occurs in the lamp bead, in an optional embodiment, under the condition that the target lamp bead parameter is not found, if the current loss degree reaches the current loss degree threshold and/or the current power error reaches the current power error threshold, the user is prompted to calibrate the light parameter of the lamp bead based on a preset light parameter calibration mode.

The current loss degree threshold and the current power error threshold are used for judging whether the light parameter deviation occurs on the lamp bead, and under the general condition, when the current loss degree reaches the current loss degree threshold and/or the current power error reaches the current power error threshold, the light parameter deviation occurs on the lamp bead is judged; otherwise, judging that the light parameter deviation does not occur on the lamp bead. As an example, the loss degree threshold of the factory-leaving lamp bead may be set to 1000, the power error threshold of the factory-leaving lamp bead may be set to 3%, and the above determination process is described by taking 1000 as the current loss degree threshold and 3% as the current power error threshold as an example: when the current loss degree reaches a current loss degree threshold value of 1000, judging that light parameter deviation occurs in the lamp bead; or when the current power error reaches 3% of the current power error threshold value, judging that the light parameter deviation occurs in the lamp bead; or when the current loss degree reaches the current loss degree threshold value 1000 and the current power error reaches the current power error threshold value 3%, judging that the light parameter deviation occurs in the lamp bead.

Optionally, if the lamp includes a display screen, the user may be prompted through the display screen to calibrate the light parameter of the lamp bead based on a preset light parameter calibration manner, for example, a corresponding prompting message is displayed on the display screen; if the lamp does not include the display screen, the display screen connected with the lamp can remind the user to calibrate the light parameter of the lamp bead based on the preset light parameter calibration mode, for example, the display screen connected with the lamp is a mobile terminal such as a mobile phone and a tablet computer, an Application program (App) can be downloaded in the mobile terminal, and the downloaded App or a small program issued by a manufacturer in the mobile terminal can remind the user to calibrate the light parameter of the lamp bead based on the preset light parameter calibration mode.

Of course, in another optional embodiment, under the condition that the target lamp bead parameter is not found, if the current loss degree does not reach the current loss degree threshold and/or the current power error does not reach the current power error threshold, when the user finds that the light parameter deviation occurs in the lamp bead, the light parameter of the lamp bead may also be calibrated based on the preset light parameter calibration mode.

Optionally, adding the loss degree in the second update package into the loss degree set under the condition that the second update package is received, so as to obtain a target loss degree set; adding the power error in the second updating packet into the power error set to obtain a target power error set; updating a loss degree section corresponding to a currently stored updating packet based on the target loss degree set, wherein the currently stored updating packet comprises a first updating packet and a second updating packet; and updating the power error interval corresponding to the currently stored updating packet based on the target power error set.

It should be noted that the second update package is a new update package, and the second update package may be a new update package that is constructed after the light parameter of the lamp bead is calibrated based on the preset light parameter calibration method. The preset light parameter calibration mode can be an off-line calibration mode of a calibration system based on a lamp bead manufacturer. The method comprises the steps of calibrating the optical parameters of the lamp beads by using a preset optical parameter calibration mode, obtaining calibrated lamp bead parameters, constructing an update package comprising the current batch information, the current loss degree, the current power error and the mapping relation among the calibrated lamp bead parameters, uploading the update package to the lamp and/or the server, and continuously updating the update package stored in the lamp and/or the server, so that the probability of obtaining the target lamp bead parameters from the update package stored in the lamp and/or the server is improved.

And 103, updating the current lamp bead parameters of the lamp beads to target lamp bead parameters so as to calibrate the light parameters of the lamp beads.

According to the obtained target lamp bead parameters, the current lamp bead parameters of the lamp beads are updated, and light parameter calibration of the lamp beads can be achieved.

On one hand, the calculation method based on the loss degree can know that the loss degree of the lamp bead is increased along with the increase of the service life; on the other hand, the lamp beads can age along with the use of the lamp beads, generally, the longer the using time is, the more serious the aging degree can influence the actual power of the lamp beads, and the more serious the aging degree is, the larger the error between the actual power corresponding to the current brightness value and the factory power corresponding to the current brightness value is; namely, the power error of the lamp bead can be increased along with the increase of the service life; therefore, in order to timely remind the user of calibrating the light parameter of the lamp bead based on the preset light parameter calibration mode when the light parameter deviation appears next time, the loss degree threshold value and/or the power error threshold value can be correspondingly updated when the light parameter of the lamp bead is calibrated.

In an alternative embodiment of the method of the invention,

optionally, after calibrating the light parameter of the lamp bead, the method includes:

acquiring a first threshold sequence, wherein the first threshold sequence comprises at least one loss degree threshold; when the current loss degree reaches a current loss degree threshold value, if a loss degree threshold value larger than the current loss degree threshold value exists in the first threshold value sequence, determining the minimum value in the loss degree threshold values larger than the current loss degree threshold value as a target loss degree threshold value; updating the current loss degree threshold value to a target loss degree threshold value;

and/or the presence of a gas in the gas,

acquiring a second threshold sequence, wherein the second threshold sequence comprises at least one power error threshold; when the current power error reaches the current power error threshold, if the power error threshold larger than the current power error threshold exists in the second threshold sequence, determining the minimum value in the power error thresholds larger than the current power error threshold as a target power error threshold; the current power error threshold is updated to the target power error threshold.

The following illustrates the update procedure of the loss degree threshold and the power error threshold:

example 1, the values in the first threshold sequence include 1000, 2000, 3000, 4000; the current loss degree threshold value is 2000, the current loss degree is 2200, at this time, the current loss degree reaches the current loss degree threshold value, so a target loss degree threshold value needs to be determined, the loss degree threshold values which are larger than the current loss degree threshold value in the first threshold value sequence comprise 3000 and 4000, the minimum value of the loss degree threshold values which are larger than the current loss degree threshold value is 3000, namely 3000 is the target loss degree threshold value; the current wear level threshold value of 2000 is updated to the target wear level threshold value of 3000.

Example 2, the values in the second threshold sequence include 3%, 5%, 7%, 9%; the current power error threshold is 5%, the current power error is 6%, at this time, the current power error reaches the current power error threshold, and therefore the target power error threshold needs to be determined, the power error threshold larger than the current power error threshold in the second threshold sequence includes 7% and 9%, the minimum value of the power error thresholds larger than the current power error threshold is 7%, that is, 7% is the target power error threshold; the current power error threshold of 5% is updated to the target power error threshold of 7%.

It should be noted that the light parameter calibration method in the above "after calibrating the light parameter of the lamp bead" is not limited, and the light parameter of the lamp bead may be calibrated according to the target lamp bead parameter, or the light parameter of the lamp bead may be calibrated based on a preset light parameter calibration method.

In sum, by updating the loss degree threshold and the power error threshold, the user can be timely reminded to calibrate the light parameter of the lamp bead based on the preset light parameter calibration mode on the basis of the updated loss degree threshold and the updated power error threshold under the condition that the target lamp bead parameter is not found next time.

To sum up, batch information of the lamp beads is an important factor influencing the light parameter calibration effect, and loss degree and power error of the lamp beads are important factors influencing the light parameter of the lamp beads, so that the accurate calibration of the light parameter of the lamp beads can be realized, the influence of parameter difference of the outgoing lamp beads on the light parameter calibration effect can be eliminated, and the light parameter calibration effect is further improved based on target lamp bead parameters obtained according to the batch information, the loss degree and the power error of the lamp beads.
