Description

Technical Field

[0001] The present invention relates to the technical field of LED lamp bead testing, and specifically provides an LED lamp bead lighting test device and a test method therefor. Background Art

[0002] Currently, the management of prefabricated building component warehouses is often chaotic, with ineffective implementation of systems, discrepancies between accounts and actual situations, resulting in uncertainties in the company's assets and inaccurate cost accounting, which affects the company's formulation of tax rate policies, income tax declaration work, and overall budget work. Moreover, the material procurement is not reasonable enough, the accuracy and predictability of procurement plan management are not strong, and the material procurement is not strictly controlled, leading to the failure to stock up on materials that need to be stocked in advance and the stocking of materials that do not need to be stocked, causing inventory backlogs, occupying a large amount of inventory funds, and bringing difficulties to work such as inventory taking, cleaning, and account reconciliation. In addition, some warehouse managers lack professional training and learning, resulting in low business levels and being unable to effectively manage the warehouse.

[0003] In a Chinese invention application with the publication number CN119406793A, an LED lamp bead lighting test device and a test method therefor are disclosed, including lamp beads. Both the front and rear side walls of the lamp beads are fixedly connected with pins, including a discharging mechanism for neatly arranging a large number of lamp beads; a detection mechanism, and the discharging mechanism can make the arranged lamp beads pass through the detection mechanism in sequence; the detection mechanism is used to energize the pins of the arranged lamp beads and screen out the lamp beads that cannot be lit; a blanking mechanism for transporting the qualified lamp beads out of the device.

[0004] In the above invention application, the lamp beads are neatly arranged by the discharging mechanism and sequentially transported to the detection mechanism for automatic detection and screening, making the entire screening process more coherent and efficient. However, each LED lamp bead still needs to be lit and detected in sequence, which is very time-consuming. Especially on a large-scale production line, the detection efficiency becomes a key factor restricting the production speed.

[0005] Therefore, the present invention provides an LED lamp bead lighting test device and a test method therefor. Summary of the Invention

The present invention calculates the static optical evaluation coefficient and the static electrical evaluation coefficient of the LED lamp bead group to be tested; calculates the static evaluation index of the LED lamp bead group to be tested, and issues an abnormal analysis warning for the LED lamp bead group to be tested; after receiving the abnormal analysis warning of the LED lamp bead group to be tested, identifies all abnormal LED lamp beads in the LED lamp bead group to be tested, recombines them to form an abnormal lamp bead group to be tested, extracts the stroboscopic index and the stroboscopic percentage, calculates the dynamic evaluation index and the static evaluation index of the abnormal lamp bead group to be tested, calculates the abnormal coefficient of the abnormal lamp bead group, and issues an abnormal warning for lamp bead production. The degree of abnormality in the LED lamp bead group is quantified, providing a basis for determining whether further measures need to be taken, thereby solving the technical problems described in the background art.

[0008] (2) Technical solution

[0009] To achieve the above object, the present invention is realized through the following technical solutions: An LED lamp bead lighting test method, including the following steps:

[0010] Collect the brightness and color temperature of the LED lamp bead group to be tested, calculate the static optical evaluation coefficient of the LED lamp bead group to be tested, and collect the working voltage , current and power of the LED lamp bead group to be tested, calculate the static electrical evaluation coefficient of the LED lamp bead group to be tested;

[0011] Obtain the static optical evaluation coefficient and the static electrical evaluation coefficient of the LED lamp bead group to be tested, calculate the static evaluation index of the LED lamp bead group to be tested, and issue an abnormal analysis warning for the LED lamp bead group to be tested;

[0012] After receiving the abnormal analysis warning of the LED lamp bead group to be tested, identify all abnormal LED lamp beads in the LED lamp bead group to be tested, recombine them to form an abnormal lamp bead group to be tested, extract the stroboscopic index Ps and the stroboscopic percentage Pb, calculate the dynamic evaluation index Dp and the static evaluation index Jp of the abnormal lamp bead group to be tested, calculate the abnormal coefficient Yc of the abnormal lamp bead group, and issue an abnormal warning for lamp bead production.

[0013] Furthermore, use an integrated optical sensor to collect the brightness and color temperature of the LED lamp bead group to be tested in real time, and calculate the static optical evaluation coefficient of the LED lamp bead group to be tested:

[0014]

[0015] Among them, i represents the sequential number of each LED lamp bead group to be tested, , m is the total number of LED lamp bead groups to be tested, m is a positive integer, represents the standard brightness of the LED lamp bead group, represents the standard color temperature of the LED lamp bead group.

[0016] Brightness refers to the luminous intensity of a light source on a unit projected area in a specific direction. To collect the brightness data of LED lamp beads, optoelectronic devices such as photoresistors or photodiodes are usually used. These sensors can respond to the light emitted by the LED lamp beads and convert it into an electrical signal. By measuring the magnitude of this electrical signal, the brightness of the LED lamp beads can be obtained indirectly.

[0017] Color temperature is a physical quantity that describes the color of a light source. It represents which wavelength of radiation is the strongest in the radiation energy of the light source, usually measured in Kelvin (K). To collect the color temperature data of LED lamp beads, devices such as color temperature meters or spectral analyzers can be used.

[0018] Furthermore, simultaneously use a power meter to collect the working voltage , current and power of the LED lamp bead group to be tested, and calculate the static electrical evaluation coefficient of the LED lamp bead group to be tested:

[0020] Among them, represents the standard power of the LED lamp bead group, represents the standard working voltage of the LED lamp bead group, represents the standard current of the LED lamp bead group.

[0021] Furthermore, obtain the static optical evaluation coefficient and the static electrical evaluation coefficient of the LED lamp bead group to be tested, and calculate the static evaluation index of the LED lamp bead group to be tested:

[0022]

[0023] The calculation formula of the static evaluation index corresponding to the LED lamp bead group to be tested is as above.

[0024] Further, when the static evaluation index of the LED lamp bead group to be measured exceeds the static threshold of the lamp bead group + , it indicates that the LED lamp bead group to be measured is abnormal, and an abnormal analysis warning of the LED lamp bead group to be measured is sent outwards; among them, represents the mean value of the static evaluation index of the historical LED lamp bead group to be measured, represents the variance of the static evaluation index of the historical LED lamp bead group to be measured;

[0025] When the static evaluation index of the LED lamp bead group to be measured does not exceed the static threshold of the lamp bead group + , it indicates that the group of LED lamp beads to be measured is qualified.

[0026] Further, after receiving the abnormal analysis warning of the LED lamp bead group to be measured, use an industrial camera to take an image of the LED lamp bead group to be measured, and use the Sobel operator to calculate the gradient amplitude of each pixel point in the image of the LED lamp bead group to be measured . When the gradient amplitude of the pixel point exceeds the standard gradient amplitude range , mark this point as an abnormal pixel point, and identify the LED lamp beads corresponding to all abnormal pixel points in the image of the LED lamp bead group to be measured, which are recorded as abnormal lamp beads.

[0027] Further, re - combine the identified abnormal lamp beads to form an abnormal lamp bead group to be measured, use a high - speed camera to shoot a video, extract the brightness value of each frame in the video , draw a brightness - time curve, and extract the stroboscopic index Ps and stroboscopic percentage Pb;

[0028] Among them, the stroboscopic index is the ratio of "the area above the average brightness" to "the total area under the curve". The larger this value is, the more serious the stroboscopic phenomenon is, and the smaller the value is, the less serious the stroboscopic phenomenon is; the stroboscopic percentage is the ratio of "the difference between the maximum brightness and the minimum brightness" to "the sum of the maximum brightness and the minimum brightness", and then multiplied by 100% to get the percentage value. The larger this value is, the greater the relative amplitude of brightness fluctuation is; the smaller the value is, the less serious the brightness fluctuation is.

[0029] Further, obtain the stroboscopic index Ps and stroboscopic percentage Pb of the abnormal lamp bead group to be measured, and calculate the dynamic evaluation index Dp of the abnormal lamp bead group to be measured:

[0030]

[0031] Among them, represents the standard stroboscopic index of the LED lamp bead group, represents the standard stroboscopic percentage of the LED lamp bead group.

[0032] Further, analyze and calculate the static evaluation index Jp of the to-be-tested abnormal LED bead group, and combine it with the dynamic evaluation index Dp of the to-be-tested abnormal LED bead group to calculate the abnormality coefficient Yc of the abnormal LED bead group:

[0033]

[0034] When the abnormality coefficient of the abnormal LED bead group exceeds the standard abnormality coefficient , send out a warning of abnormal LED bead production;

[0035] Among them, the analysis method of the static evaluation index Jp of the to-be-tested abnormal LED bead group is the same as that of the static evaluation index of the to-be-tested LED bead group.

[0036] An LED bead lighting test device includes:

[0037] A bead abnormality analysis module that collects the brightness and color temperature of the to-be-tested LED bead group, calculates the static optical evaluation coefficient of the to-be-tested LED bead group, and collects the working voltage , current and power of the to-be-tested LED bead group, and calculates the static electrical evaluation coefficient of the to-be-tested LED bead group;

[0038] A bead abnormality warning module that obtains the static optical evaluation coefficient and the static electrical evaluation coefficient of the to-be-tested LED bead group, calculates the static evaluation index of the to-be-tested LED bead group, and sends out an abnormality analysis warning for the to-be-tested LED bead group;

[0039] An abnormal bead analysis module, after receiving the abnormality analysis warning of the to-be-tested LED bead group, identifies all abnormal LED beads in the to-be-tested LED bead group, recombines them to form a to-be-tested abnormal LED bead group, extracts the stroboscopic index Ps and the stroboscopic percentage Pb, calculates the dynamic evaluation index Dp and the static evaluation index Jp of the to-be-tested abnormal LED bead group, calculates the abnormality coefficient Yc of the abnormal LED bead group, and sends out a warning of abnormal LED bead production.

[0061] Step Two: Obtain the static optical evaluation coefficient and static electrical evaluation coefficient of the LED lamp bead group to be measured, calculate the static evaluation index of the LED lamp bead group to be measured, and send out an abnormal analysis warning for the LED lamp bead group to be measured.

[0066] Step 202: When the static evaluation index of the LED lamp bead group to be measured exceeds the static threshold + of the lamp bead group, it indicates that the LED lamp bead group to be measured is abnormal, and an abnormal analysis warning for the LED lamp bead group to be measured is sent out.
