In the scenes of using the LED lamps in a large quantity, the LED lamps can quickly reach ten thousand working hours to generate relatively obvious brightness attenuation due to long-term working, and the brightness attenuation is caused by lumen attenuation; the common processing method is to directly replace the LED lamp or adjust (such as adjusting) the parameters of the driving power supply one by one or uniformly to supplement the LED lamp, so as to achieve the purposes of constant lumen and maintaining the original brightness.
However, the direct replacement in the above treatment method is excessively wasteful, because the LED lamp has a certain degree of attenuation, but still retains 80% to 90% of performance, and the direct replacement clearly greatly increases maintenance cost; if the parameters are adjusted one by one in the adjustment mode, the attenuation degree of the LED lamps is detected one by one manually, and then the parameters are adjusted, so that the workload is high; if the adjustment is unified, some non-attenuation LED lamps passively adjust the parameters of the driving power supply, and the error adjustment occurs.

An NFC-based LED lamp dimming system and method according to an embodiment of the present invention are described below with reference to fig. 1 to 3.
Example 1
An NFC-based LED lamp dimming system comprises a mobile terminal 1 provided with an NFC master device and a driving power supply 2 provided with an NFC slave device; the mobile terminal 1 comprises an NFC identification module 11, a parameter display module 12, a parameter editing module 13 and a parameter writing module 14;
The mobile terminal 1 is configured to, when the driving power supply 2 approaches, read a first power supply parameter of the driving power supply 2 by the NFC recognition module 11 and transmit the first power supply parameter to the parameter display module 12 and the parameter editing module 13;

the parameter writing module 14 is configured to write the first adjustment power parameter to the driving power supply 2 when the first adjustment power parameter is received.
In the preferred embodiment of the present invention, as shown in fig. 1, according to the electromagnetic induction principle between a mobile terminal 1 (such as a mobile phone) provided with an NFC master device and a driving power supply 2 (both of which are powered by the driving power supply) provided with an NFC slave device, when an operator holds the mobile terminal 1 near the driving power supply 2, an NFC identification module 11 can read a first power supply parameter of the driving power supply 2, and the NFC identification module 11 transmits the read first power supply parameter to a parameter display module 12, so that the first power supply parameter can be displayed on an operation interface of the mobile terminal 1 for the operator to browse; the NFC recognition module 11 transmits the read first power supply parameter to the parameter editing module 13, after an operator browses the first power supply parameter and observes the actual brightness of the LED lamp, the performance attenuation condition of the LED lamp is comprehensively judged, then the first power supply parameter is adjusted through the operation interface of the mobile terminal 1 to compensate the attenuation performance of the LED lamp, namely, the first adjustment power supply parameter is generated by the parameter editing module 13 and transmitted to the parameter writing module 14, the first adjustment power supply parameter is written into the driving power supply 2, then the driving power supply 2 drives the LED lamp according to the first adjustment power supply parameter (the driving power supply 2 can be in an on state to drive the LED lamp to change along with the on state, or the driving power supply 2 can be in an off state, and the LED lamp can be directly driven according to the first adjustment power supply parameter after the next on), so that the LED lamp keeps the original lumen, the constant brightness effect is achieved, and the brightness is restored to the state before attenuation; meanwhile, the first adjustment power supply parameters are displayed on an operation interface of the mobile terminal 1 through the parameter display module for operators to browse, and then the operators can finally confirm whether the LED lamp is restored to the original constant current state or not through the comparison of the adjustment power supply parameters and the actual brightness change condition of the LED lamp, so as to judge whether the adjustment of the power supply parameters is needed to be continued or not.
Therefore, through NFC technology, when the operator approaches the driving power supply 2 of one or more LED lamps by using the mobile terminal 1, the attenuation degree of all the LED lamps driven by the driving power supply 2 can be conveniently and simultaneously detected, the parameters of the LED lamps can be conveniently browsed, and the one or more LED lamps can be adjusted for multiple times at the equipment operation interface to compensate the performance of the LED lamps, so that repeated operation of detecting and adjusting the LED lamps one by one manually is avoided, and the workload is greatly reduced; the actual adjusting effect of the LED lamps can be observed and compared until the LED lamps are adjusted to a constant current bright state satisfactory to operators, the constant current bright effect is better, the LED lamps do not need to be frequently replaced, and the waste of the lamps is avoided; more importantly, the lamp can be further expanded and regulated to other lumen states, and is not limited to constant lumen states.
It should be noted that, the operation mode of the mobile terminal parameter modification instruction input parameter editing module 13 may be: after the mobile terminal 1 detects the driving power supply 2, the first power supply parameter is displayed in the form of a brightness adjustment bar (the parameter is exemplified by brightness) on the operation interface, and an operator generates the first adjustment power supply parameter by sliding the progress of adjusting the brightness adjustment bar, and the adjustment bar adjustment process is a parameter modification instruction input process.
Further, the parameter modification instruction includes adjusting a current parameter.
In this embodiment, if the driving power supply 2 of the LED lamp is required to adjust the lumens of the LED lamp to the original lumens, the luminous flux can be adjusted by adjusting the power supply current percentage (i.e. adjusting the current parameter) only under the condition that other parameters are unchanged, so that the lumens of the LED lamp are adjusted to the original lumens, and the lumens are kept constant.
Further, the mobile terminal 1 further comprises a parameter analysis module 15 and a self-adjustment module 16;
The parameter analysis module 15 is configured to receive the first power parameter and the first adjusted power parameter, calculate and record an adjustment difference value between the first power parameter and the first adjusted power parameter;
The self-adjusting module 16 is configured to receive the second power parameter from the NFC identifying module 11 when the intelligent adjusting function is turned on, read the adjustment difference value from the parameter analyzing module 15, adjust the second power parameter according to the adjustment difference value to generate a second adjusted power parameter, and transmit the second adjusted power parameter to the parameter displaying module 12 and the parameter writing module 14;
The parameter writing module 14 is further configured to write the second adjustment power parameter to the driving power supply 2 when the second adjustment power parameter is received.
In this embodiment, as shown in fig. 2, when the number of LED lamps to be adjusted is relatively large, if the comprehensive conditions such as the brightness condition, the driving power parameter condition, the installation batch and the like of the plurality of LED lamps are close, the driving power 2 of each LED lamp can be manually adjusted to a constant brightness state without an operator, which is a repetitive operation; therefore, when the driving power supply 2 of one of the LED lamps is adjusted and faces the LED lamps with the same situation (i.e. the first power supply parameter and the second power supply parameter are similar), the intelligent adjusting function can be directly used along the adjusting mode (i.e. the adjusting difference value) adjusted last time, and the self-adjusting module 16 can adjust the second power supply parameter of the driving power supply 2 to the second adjusting power supply parameter according to the adjusting difference value; meanwhile, the operation interface of the mobile terminal 1 is displayed for the operator to browse and judge through the parameter display module 12.
It should be noted that, the adjustment difference is a difference result between the first power parameter and the first adjustment power parameter, and since the first power parameter and the second power parameter are similar, the amplitude of adjustment to the constant current state is also similar.
Further, the mobile terminal 1 is further configured to select one or more driving power sources 2 for processing when the plurality of driving power sources 2 are close to each other.
In the embodiment, when the conditions of a plurality of LED lamps are similar, in order to avoid that each driving power supply 2 recognizes and intelligently adjusts the workload once, the time is long, and the efficiency is low; the mobile terminal 1 can perform constant lumen adjustment on a plurality of driving power supplies 2 at the same time, namely, the NFC recognition module 11 recognizes all the selected driving power supplies 2, the parameter editing module 13 uniformly adjusts the selected driving power supplies 2 according to the same manual adjustment parameter change or adjustment difference value when performing manual adjustment or intelligent adjustment, the parameter writing module 14 writes the corresponding driving power supplies 2, and the parameter display module 12 selectively adjusts the data of a certain selected driving power supply 2 at an operation interface.
Further, the parameter display module 12 is configured to receive the first power parameter and the first adjusted power parameter, generate a first chart data item, and fit the original constant lumen graph and the first adjusted constant lumen graph;
The parameter presentation module 12 is further configured to receive a second power parameter and a second adjusted power parameter, generate a second chart data item, and fit a second original constant lumen profile and a second adjusted constant lumen profile.
In this embodiment, the parameter display module 12 is configured to display the status of the LED lamp on the operating interface of the mobile terminal 1 for the operator to intuitively display, so that the data is presented in the form of a graph and a curve, which is convenient for the operator to browse and perform subsequent operations. Wherein the first chart data item includes content of a first power supply parameter and a first adjusted power supply parameter, the original constant lumen graph is fitted by the first power supply parameter, and the first adjusted constant lumen graph is fitted by the first adjusted power supply parameter; the second chart data item includes content of a second power supply parameter and a second adjusted power supply parameter, a second original constant lumen graph is fitted by the second power supply parameter, and a second adjusted constant lumen graph is fitted by the second adjusted power supply parameter.
Further, the parameter modification instruction further comprises adjusting a color temperature parameter and adjusting a constant brightness parameter.
In this embodiment, if the driving power supply 2 of the LED lamp is to adjust the lumens of the LED lamp to the original lumens, besides adjusting the percentage of the supply current, the driving power supply can be realized in combination with color temperature adjustment to cope with the situation that the supply current cannot be excessively increased; even the constant lumen value can be directly reset, so that the LED lamp can form a new constant lumen state; the parameter modification instructions may thus also include adjusting a color temperature parameter and adjusting a constant brightness parameter.
Further, the first power supply parameter includes a current parameter, a color temperature parameter, and a constant current parameter.
In this embodiment, in order to implement all parameter modification instructions, it is first necessary to know how the parameters of the original driving power source 2 are, so that the first power source parameters need to include a current parameter, a color temperature parameter and a constant current parameter, and the operation interface displayed on the mobile terminal 1 is convenient for an operator to adjust according to the original parameters.

Further, the method also comprises the following steps:
S5: after the step S4 is finished, if the intelligent regulation function is started by clicking on the operation interface of the mobile terminal, the mobile terminal calculates and records the regulation difference value of the first power supply parameter and the first regulation power supply parameter;
s6: when the driving power supply is identified next time, the second power supply parameter of the driving power supply is clicked and read on the mobile terminal operation interface, the second power supply parameter is automatically adjusted according to the adjustment difference value, the second adjustment power supply parameter is generated, and meanwhile, the mobile terminal writes the second adjustment power supply parameter into the driving power supply until the mobile terminal operation interface prompts that writing is successful.
In this embodiment, in order to adjust the driving power parameters in batches under the condition that the fading conditions of a plurality of LED lamps are similar, an intelligent adjusting function is set at the mobile terminal, and this function uses the principle that the parameter adjusting amplitude will be similar under the condition that the fading conditions of the LED lamps are similar, and uses the adjusting difference value after the first manual adjustment as the intelligent adjusting standard, and directly starts the intelligent adjusting function to quickly adjust the LED lamps with similar conditions.

s21: selecting one or more driving power supplies in a mobile terminal operation interface;

Specifically, for example, when a plurality of driving power supplies are identified, the mobile terminal operation interface correspondingly presents a plurality of driving power supply options, an operator clicks and reads a first power supply parameter of the driving power supply to be operated, then the mobile terminal operation interface presents a plurality of progress adjustment bars, each progress adjustment bar represents the current progress (i.e. the first power supply parameter) of one driving power supply corresponding to the parameter, the operator comprehensively judges the fading condition, and the fading condition is similar to be checked together to carry out batch processing (for example, the progress adjustment bars are slid together).
