DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] With the development of product technology, the medical display field requires multiple brightness levels for different status prompts, and LED (Light Emitting Diode) lamps are usually used to obtain multiple brightness levels. However, there are large differences in brightness between different batches of LEDs, and there are also relatively large differences in brightness between different brands of LED lamps. The brightness of LED lamps will also vary with the length of use. In the existing technology, the brightness of LED lamps will be calibrated after the production is completed to avoid differences in brightness between different batches and brands of LED lamps. However, calibration after production cannot guarantee that the brightness of LED lamps will not vary during use.

[0020] In order to solve the above problems, embodiments of the present invention provide a method, device, equipment, storage medium and program product for controlling the brightness of a lamp.

[0021] Figure 1 This is one of the flow charts of the method for controlling the brightness of a lamp provided in an embodiment of the present invention. In some embodiments of the present invention, the execution subject of the method for controlling the brightness of a lamp may be a lamp equipped with a control element, or a lamp mainboard, or an electronic device connected to the lamp. Figure 1 As shown, the method may include the following steps.

[0022] Step 101, obtaining the first gear position and the first brightness value of the lamp currently in use.

[0023] Among them, the lamps in use refer to lamps that have been used in actual application scenarios. They can be LED lamps in the medical field, LED lamps used in other fields, or other lamps with lighting functions.

[0024] In some embodiments, the lamp may have one or more gears, each gear corresponding to a specific brightness value. The first gear currently turned on refers to the gear currently turned on by the lamp, and the first brightness value refers to the current brightness value of the lamp. As a possible implementation, the first gear of the lamp currently turned on can be determined based on the user's turn-on operation at the front end, or can be determined based on the size of the voltage signal converted from the current currently input to the lamp. For example, the correspondence between different gears and the size range of the voltage signal can be pre-configured, and the corresponding gear can be determined based on the size of the voltage signal converted from the current input to the lamp.

[0025] As a possible implementation, the first brightness value of the lamp can be obtained by detecting the brightness of the lamp through a brightness detection unit. The brightness detection unit is connected to the lamp, and the brightness detection unit can be configured in the lamp or on a main board of the lamp.

[0026] Step 102, determining a first expected brightness value corresponding to a first gear position from a configuration table; the configuration table stores a mapping relationship between the gear positions of the lamp and the expected brightness values.

[0027] That is to say, the mapping relationship between the lamp gears and the expected brightness values ​​is stored in the configuration table in advance, and the expected brightness value refers to the specific brightness value corresponding to each gear of the lamp.

[0028] Step 103: Based on the first brightness value and the first expected brightness value, adjust the current currently input to the lamp so that the brightness value of the lamp is close to the first expected brightness value.

[0029] It can be understood that if the first brightness value is greater than or equal to the first expected brightness value, it means that there is a difference in the brightness of the first gear of the current lamp, so the current input to the lamp needs to be adjusted to control the brightness of the lamp to be close to the first expected brightness value.

[0030] In some embodiments, the first brightness value can be compared with the first expected brightness value. If the first brightness value is consistent with the first expected brightness value, there is no need to adjust the current input to the lamp. If the first brightness value is inconsistent with the first expected brightness value, the difference between the first brightness value and the first expected brightness value is determined, and based on the difference, an adjusted current value is determined, and the adjusted current value is transmitted to the lamp.

[0031] In some embodiments, the process of adjusting the current currently input to the lamp based on the first brightness value and the first expected brightness value may include the following steps.

[0032] Step S11: if the difference between the first brightness value and the first expected brightness value is smaller than a threshold value, the current currently input to the lamp is kept unchanged.

[0033] That is to say, a brightness difference threshold that does not affect actual use can be preset. If the difference between the first brightness value and the first expected brightness value is less than the threshold, it means that the current brightness difference of the lamp does not affect actual use, and the brightness of the lamp does not need to be controlled.

[0034] Step S12: if the difference is greater than or equal to the threshold, adjust the current currently input to the lamp based on the difference.

[0035] If the difference between the first brightness value and the first expected brightness value is greater than or equal to the threshold, it means that the current brightness difference of the lamp has affected actual use, and the input current of the lamp needs to be adjusted so that the difference between the brightness value of the lamp and the first expected brightness value is less than the threshold.

[0036] In some embodiments, the current currently input to the lamp can be adjusted based on the difference. For example, the circuit parameters that need to be adjusted can be determined based on the difference, and the current currently input to the lamp can be adjusted by adjusting the circuit parameters.

[0037] As an example, if the first brightness value is greater than the first expected brightness value, and the difference between the two is greater than or equal to a threshold value, the circuit parameters can be adjusted to reduce the current input to the lamp to reduce the brightness value of the lamp; if the first brightness value is less than the first expected brightness value, and the difference between the two is greater than or equal to the threshold value, the circuit parameters can be adjusted to increase the current input to the lamp to increase the brightness value of the lamp.

[0038] That is to say, the method for controlling the brightness of the lamp in the embodiment of the present invention can control the brightness in real time during the use of the lamp, and automatically calibrate the brightness of the lamp, so that the brightness of the lamp during use can always be close to the expected brightness value, avoiding the problem of lamp brightness difference.

[0039] According to the method for controlling the brightness of a lamp of an embodiment of the present invention, the first gear position currently turned on by the lamp in use and the first brightness value are obtained; the first expected brightness value corresponding to the first gear position is determined from the configuration table; the mapping relationship between the gear position of the lamp and the expected brightness value is stored in the configuration table; based on the first brightness value and the first expected brightness value, the current currently input to the lamp is adjusted so that the brightness value of the lamp is close to the first expected brightness value. The present invention obtains the brightness value of the lamp in real time, compares it with the expected brightness value, and adjusts the current currently input to the lamp so that the brightness value of the lamp is close to the expected brightness value, thereby automatically controlling the brightness of the lamp during use and avoiding the problem of inconsistent brightness during use. In addition, since the present invention can control the brightness of the lamp during use, the calibration work after the lamp is produced can be eliminated, thereby reducing the cost of the calibration work.

[0040] Figure 2 The second flow chart of the method for controlling the brightness of a lamp provided by an embodiment of the present invention. Figure 2 As shown, based on the above embodiment, the implementation process of adjusting the current currently input to the lamp based on the difference may include the following steps.

[0041] Step 201, determining a current adjustment value according to the difference.

[0042] In some embodiments, a large number of experiments can be conducted in advance to record the difference between the actual brightness value and the expected brightness value, and the corresponding relationship between the current adjustment value. This corresponding relationship can be a relationship curve between the difference and the current adjustment value, or a correspondence table between the difference range and the current adjustment value. Based on this corresponding relationship, the current adjustment value corresponding to the current difference can be determined.

[0043] Step 202, adjusting the current currently input to the lamp based on the current adjustment value.

[0044] In some embodiments, the current currently input to the lamp can be adjusted by adjusting the circuit parameters. As an example, the current input to the lamp can be adjusted by adjusting the resistance of a digital potentiometer in the circuit where the lamp is located. Adjusting the current currently input to the lamp based on the current adjustment value may include: determining a resistance adjustment value of the digital potentiometer based on the current adjustment value; and adjusting the resistance of the digital potentiometer based on the resistance adjustment value to adjust the current currently input to the lamp.

[0045] According to the method for controlling the brightness of a lamp in an embodiment of the present invention, a current adjustment value is determined according to the difference; based on the current adjustment value, the current currently input to the lamp is adjusted. The brightness of the lamp can be efficiently controlled to the expected value through the current adjustment, thereby minimizing the impact of the brightness difference on actual use.

[0046] Figure 3 The third flow chart of the method for controlling the brightness of a lamp provided by an embodiment of the present invention. In some embodiments, the configuration table also stores the mapping relationship between the gear position of the lamp and the magnitude of the input current. For example, when the lamp is turned on, the configuration table can be directly configured to determine the magnitude of the current required to be input to the lamp for the currently turned-on gear position, and the corresponding magnitude of the input current is input to the lamp. Figure 3 As shown, the method may include the following steps.

[0047] Step 301, obtaining the first gear position and the first brightness value of the lamp currently in use.

[0048] Step 302: determine a first expected brightness value corresponding to a first gear from a configuration table; the configuration table stores a mapping relationship between the gears of the lamp and the expected brightness values.

[0049] Step 303: Based on the first brightness value and the first expected brightness value, adjust the current currently input to the lamp so that the brightness value of the lamp is close to the first expected brightness value.

[0050] Step 304: Update the corresponding relationship between the adjusted current and the first gear into the configuration table.

[0051] It is understandable that during the use of the lamp, the brightness difference caused by the attenuation trend is usually irreversible. Therefore, in order to improve the efficiency of lamp brightness control and enhance the user experience, the corresponding relationship between the magnitude of the current after each adjustment and the first gear can be updated to the configuration table. In other words, the corresponding relationship between the magnitude of the input current after the latest adjustment and the gear is stored in the configuration table.

[0052] As a possible implementation method, each time the current is adjusted, the current input current can be determined from the configuration table, and the current adjustment value can be determined based on the brightness difference, and the current adjustment can be achieved by adjusting the resistance of the digital position meter; based on the input current and the current adjustment value, the size of the adjusted input current can be determined, and the correspondence between the size of the adjusted current and the first gear can be updated in the configuration table.

[0053] In some embodiments, the following steps may be included before obtaining the first gear value and the first brightness value of the lamp currently in use.

[0054] Step S31, in response to the start-up operation corresponding to the first gear, determining the magnitude of the first input current corresponding to the first gear from the configuration table.

[0055] Since the configuration table stores the correspondence between the size of the most recently adjusted input current and the gear position, each time the lamp is turned on, the size of the input current of the current turning-on gear is determined based on the configuration table, so that the brightness of the lamp can reach the expected brightness when it is turned on. This not only ensures the consistency of brightness during the use of the lamp, but also avoids repeated current adjustment, thereby improving the efficiency of brightness control.

[0056] Step S32: inputting the first input current into the lamp according to the magnitude of the first input current.

[0057] In some embodiments, based on the magnitude of the first input current, the resistance of the digital potentiometer can be adjusted to a corresponding resistance value to obtain a first input current of a corresponding magnitude, and then input the first input current into the lamp.

[0058] In other embodiments, the corresponding relationship between the lamp gear and the resistance value of the digital potentiometer can be stored in the configuration table, that is, after each adjustment, the latest corresponding relationship between the lamp gear and the resistance value of the digital potentiometer is updated to the configuration table. When the lamp is turned on, the resistance value corresponding to the current on gear is directly determined from the configuration table, and the resistance of the digital potentiometer is adjusted to the resistance value, and the obtained first input current is input to the lamp. During the use of the lamp after it is turned on, the difference between the brightness value of the lamp and the expected brightness value can be monitored in real time, and the input current can be adjusted in time, so that the brightness of the lamp can be kept consistent during use.

[0059] According to the method for controlling the brightness of a lamp according to an embodiment of the present invention, after adjusting the current currently input to the lamp based on the first brightness value and the first expected brightness value, the corresponding relationship between the magnitude of the adjusted current and the first gear is updated in the configuration table, so that the configuration table contains the latest corresponding relationship between the magnitude of the current and the gear. In addition, the method also includes, in response to the start-up operation corresponding to the first gear, determining the magnitude of the first input current corresponding to the first gear from the configuration table; and inputting the first input current to the lamp according to the magnitude of the first input current. The present invention can ensure that when the lamp is turned on, a current of a corresponding magnitude is input to the lamp based on the latest adjusted current magnitude, so as to avoid the brightness difference when the lamp is turned on affecting normal use, and can also avoid repetitive current adjustment to improve the efficiency of brightness control.

[0060] In order to implement the above embodiment, the present invention also provides a device for controlling the brightness of a lamp.
