Description

[0003] LED lamps contain many electronic components, such as LED lamp beads / chips, power supplies (voltage conversion, voltage stabilization circuits, components), and any minor damage to any electronic component may cause the entire LED lamp to fail. Therefore, important LED lamps need to undergo a certain period of aging testing after production and before leaving the factory. This is done by continuously powering on the lamps for several hours to detect the stability of the internal electronic components and eliminate potential faults before packaging and shipment.

[0004] However, the current conventional aging test for LED lamps is to simply pass 220V AC power to the LED lamps. After the aging time is up, the workers visually check whether the LED lamps are working normally. Those that can emit light normally are qualified products, while those that do not emit light or some of the lamp beads have attenuated brightness are unqualified products and need to be reworked and repaired before re-aging test. The defect is that for unqualified products, they can only be disassembled and the LED light board and power supply replaced and matched again, but it is difficult to count and analyze the specific model and specification of electronic components that cause damage, and even the probability of damage of this type of electronic components, how long it takes to work before it is easily damaged, etc., which leads to greater randomness in product quality.

[0039] Further, more specifically, in a preferred embodiment, the step S300 of the lamp intelligent aging test fault diagnosis method is implemented as follows: Send instructions to control the camera to take group photos of the LED lights in the test group and obtain the feedback camera data; calibrate the position of the lamps, for example, calibrate the number of the lamp in the current test group as m; record the LED lighting conditions; When the LED light is normal, the camera data output is L mt =0, where L mt Output judgment parameters for the camera; When the LED light is abnormal, if it is completely off or flickering, the camera captures the off-light moment and the camera data output is L mt =1.

[0040] Further, more specifically, in a preferred embodiment, the step S400 of the lamp intelligent aging test fault diagnosis method is implemented as follows: Retrieve the first output judgment parameter f1 and the camera output judgment parameter L mt Perform troubleshooting; When f1=1, or L mt =1, activate fault diagnosis; According to f1=1, or L mt =1, read the standard stable current I t , T=[t-t1, t+t2], where t1 is the time before the fault occurs, preferably 10 seconds; t2 is the time after the fault occurs, preferably 2 seconds; Get the current measured abnormal current minimum value I Tmin , and the current measured abnormal current maximum value I Tmax ; Calculate the current measured abnormal current minimum value I Tmin With the standard stable current I t The ratio W min, the formula is: W min =I Tmin / I t ; Get the minimum value Cminti of the input current change over time t; Execute calculation W min / Cminti, when the calculation result is greater than or equal to 1, the output R=0, R is the fault diagnosis output judgment parameter corresponding to the minimum current; When W min / When Cminti is less than 1, output R=1; When it is detected that R is equal to 0, there is no output, and the fault type is recorded and fed back as a circuit breaker fault; When R is greater than 0, the fault type is recorded as LED chip failure, and the current maximum value of the measured abnormal current I is calculated.

[0043] When it is detected that the estimated lamp usage time has been reached, a reminder message to replace the lamp will be fed back.

[0044] It can be understood that the actual working stable current I of the mth lamp is stm Compared with standard value I st If it is large, the internal heat will be greater, which may lead to accelerated aging.

[0066] It is worth mentioning that even for normal LED lamps, there will be certain power data fluctuations during the aging test process. Based on this, a database of lamp usage is established. In the subsequent use of LED lamps, the use time of the damaged lamps and the actual fault conditions after the lamps are disassembled are recorded, and the database of lamp usage is continuously updated and optimized. It is understandable that the service life of LED lamps can be judged based on the aging test process data of normal LED lamps leaving the factory. If the service life does not meet expectations, the electronic components can be replaced in advance. If the service life meets expectations, it will be delivered and used normally. During use, the maintenance and replacement intervals are set according to the expected life. Under the premise of ensuring the lighting effect, the working time of LED lamps is extended as much as possible, the replacement frequency is reduced, and the maintenance costs are saved. At the same time, the lighting safety of the lighting venue can be guaranteed to avoid emergency repairs caused by accidental damage. The replaced and disassembled LED lamps are returned to the factory for inspection to determine the aging of the internal electronic components, and compared with the previous report of the lamp usage database, and the lamp usage database is continuously updated and optimized.

[0067] It is worth mentioning that the diagnostic database and lamp usage database constructed according to the intelligent aging test fault diagnosis system for lamps can analyze the service life, failure frequency, and mutual matching of each electronic component, establish an option database for electronic components, and provide data support for the subsequent design and production of lamps, so that the overall failure of LED lamps is reduced and the design life is consistent with the actual service life.

Preferably, A<98%, B>102%, and the threshold is appropriately expanded by about 2% to perform data accommodation.

[0070] More specifically, the test data real-time comparison unit includes an input current data ratio calculation module, a current parameter judgment module, and a judgment parameter output module. The input current data ratio calculation module calculates the ratio of the measured input current to the standard stable current, and the formula is: K t =I int / I t , where K t is the current measured input current I int With the standard stable current I t The current parameter judgment module is configured to obtain the calculation result of the input current data ratio calculation module and perform judgment: when K t Falls into C t =[Cminti, Cmaxti], the current parameters are considered normal; when K t Beyond C t When the current parameter is within the range, it is judged that the current parameter is abnormal, and the LED lamp under test is judged to be abnormal. The judgment parameter output module obtains the judgment result of the current parameter judgment module, and when the current parameter is normal, outputs f1=0, where f1 is the first output judgment parameter; when the current parameter is abnormal, outputs f1=1.

[0071] More specifically, the monitoring data comparison unit includes a data acquisition control module, a calibration module, a luminous recording module, a monitoring data comparison and judgment module, and a camera judgment parameter output module.

The calibration module controls the lamp position for calibration and obtains calibration information. The luminous recording module records the LED luminous conditions. The monitoring data comparison and judgment module obtains monitoring data from the data acquisition control module, and performs comparison and judgment in combination with the camera monitoring data.

[0075] When the minimum current corresponding fault diagnosis output judgment parameter R in the minimum current corresponding fault diagnosis output judgment module is greater than 0, the fault record feedback module records the fault type as LED chip fault.

[0076] Further, when the minimum current corresponding fault diagnosis output judgment parameter R in the minimum current corresponding fault diagnosis output judgment module is greater than 0, the maximum current corresponding fault diagnosis output judgment module is started. The maximum current corresponding fault diagnosis output judgment module is configured to execute: Calculate the current maximum value of the measured abnormal current I Tmax With the standard stable current I t The ratio W max , the formula is W max =I Tmax / I t ; Get the maximum value Cmaxti of the time t change of the input current; Execute calculation W max / Cmaxti, when the calculation result is less than or equal to 1, the output S=0, S is the fault diagnosis output judgment parameter corresponding to the maximum current; When W max When / Cmaxti is greater than 1, output S=1.

[0080] It can be understood by those skilled in the art that the actual working stable current I of the m-th lamp is stm Compared with standard value I st If it is large, the internal heat will be greater, which may lead to accelerated aging.

[0081] like Figure 3-5 As shown, according to another aspect of the present invention, in another preferred embodiment of the present invention, a specific implementation of a lamp intelligent aging test fault diagnosis device that applies the lamp intelligent aging test fault diagnosis method and the lamp intelligent aging test fault diagnosis system of the present invention is also explained. The lamp intelligent aging test fault diagnosis method and the lamp intelligent aging test fault diagnosis system of the present invention can both be applied to the lamp intelligent aging test fault diagnosis device. Specifically, preferably, the lamp intelligent aging test fault diagnosis device includes an aging test control cabinet 1 and an aging test rack 2. A plurality of lamp grids 21 are distributed on the aging test rack 2, with lamp grids 21 on both sides. A terminal 22 is provided at the mouth of each lamp grid 21. The lamp to be tested for aging is placed individually in the lamp grid 21, and then the wire is connected to the terminal 22. The power supply is turned on to start the aging test. The detection instrument in the aging test control cabinet 1 monitors the single-channel power supply parameters and sends the data to the data server 4 through the communication module; the aging test control cabinet 1 is connected to the 220V power supply through the power supply cable 16 to provide input power for the aging test control cabinet 1; the 220V power supply is then divided and passed through each power supply parameter detection instrument, and then connected to each terminal 22 on the aging test rack 2 through the output cable 17; the communication module in the aging test control cabinet 1 sends the collected data to the data server 4 through the communication cable 18.

[0083] Furthermore, a monitoring camera 3 is installed on the outside of the aging test frame 2. When the LED lamp is undergoing an aging test, the luminous surface faces the monitoring camera 3. The monitoring camera 3 positions the lamp grid 21 and then identifies the luminous state of the LED lamp. Normal luminescence is the normal state. When the LED lamp is undergoing an aging test and the luminescence of individual LED lamp beads / chips decays, the luminous intensity is reduced. Even when individual LED lamp beads / chips are damaged, they will no longer emit light. This abnormal situation will be captured by the monitoring camera 3, and the information will be recorded and sent to the data server 4 for storage and analysis simultaneously with the information recorded by the power supply parameter detection instrument. If a power failure occurs, all LED lamp beads / chips of a single LED lamp will decay or stop emitting light. This abnormal situation will also be captured by the monitoring camera 3, and the information will be recorded.

[0087] Preferably, for example, in a specific preferred embodiment, the intelligent aging test fault diagnosis system for lamps is configured to perform: data collection of the aging process of LED lamps; setting the environmental parameters of the test room, or the aging test rack 2, or the lamp grid 21 according to the use environment of the LED lamp product; for some parts that need to be used in special environments, special test environments can also be constructed, such as low temperature, high temperature, high humidity, etc.; then the aging test of the LED lamp is started; the aging test control cabinet 1 and the monitoring camera 3 work together to collect power supply data and camera monitoring data, store and send them to the data server 4, and use the data to jointly judge whether the LED lamp is abnormal. If normal, it indicates that it can be arranged for shipment and delivery for use. If abnormal, fault diagnosis is performed, and finally the LED lamp is repaired.
