[0026] The present application provides a method for controlling a flashlight. Figure 1 The process diagram of the flash control method in the embodiment of the present application is as follows Figure 1 , used in electronic devices, including but not limited to smartphones, tablets and cameras. Figure 1 As shown, the control method of the flash lamp includes the following steps:

[0027] S101: Obtaining a resistance value collected by a thin-film temperature sensor; wherein the thin-film temperature sensor is attached to an inner surface or an outer surface of a flash lamp.

[0028] In the embodiment of the present application, the thin film temperature sensor is a temperature sensor based on a thin film material. The thin film temperature sensor works by utilizing the property that the resistance of the thin film material changes with temperature. When the external temperature changes, the resistance value of the thin film material will change accordingly. Therefore, the thin film temperature sensor can directly measure and reflect the change in resistance value. At the same time, through specific calibration or conversion, the change in resistance value can also be converted into a temperature value.

[0029] In an embodiment of the present application, a thin film temperature sensor is attached to the inner surface or outer surface of the flash lamp, so that the thin film temperature sensor is very close to the flash lamp. In this way, the temperature of the flash lamp can be accurately estimated based on the resistance value collected by the thin film temperature sensor, thereby accurately adjusting the working state of the flash lamp to achieve the purpose of temperature regulation.

[0030] S102: Based on the resistance value, control the working state of the flash lamp.

[0031] In some embodiments of the present application, the thin film temperature sensor and the copper foil trace are formed into an integrated structure, and the copper foil trace is a copper foil trace of a flexible printed circuit board directly connected to the flash lamp.

[0032] In the embodiment of the present application, when the flash is connected to the device mainboard through a flexible printed circuit board (FPC), the thin film temperature sensor and the copper foil wiring of the flexible printed circuit board are made into an integrated structure, and the flexible printed circuit board is arranged in the internal space of the flash, or is attached to the inner / outer surface of the flash, so that the thin film temperature sensor is very close to the flash, so that the temperature of the flash can be accurately estimated based on the resistance value collected by the thin film temperature sensor, so as to accurately adjust the working state of the flash to achieve the purpose of temperature regulation and ensure that the flash will not be damaged. Among them, the device mainboard is used to power the flash through the flexible printed circuit board.

[0033] In some embodiments of the present application, the thin film temperature sensor and the copper foil wiring are formed into an integrated structure, and the copper foil wiring is a copper foil wiring of a device main board or a sub-board directly connected to the flash lamp.

[0034] In the embodiment of the present application, when the flashlight is directly connected to the device mainboard, the device mainboard is arranged outside the flashlight, and the thin-film temperature sensor can be formed into an integrated structure with the copper foil trace of the device mainboard directly below the flashlight, or other positions, as long as the distance from the flashlight is within the preset threshold range, the accuracy of the collected resistance value can be guaranteed within the preset threshold range, and then the temperature of the flashlight can be accurately estimated, so as to accurately adjust the working state of the flashlight, so as to achieve the purpose of temperature regulation and ensure that the flashlight will not be damaged. Among them, the device mainboard is used to directly power the flashlight.

[0035] In the embodiment of the present application, when the flashlight is directly connected to the device sub-board, the device sub-board is arranged inside the flashlight, and the thin film temperature sensor and the copper foil wiring of the device sub-board are formed into an integrated structure; when the device sub-board is arranged outside the flashlight, the thin film temperature sensor can be formed into an integrated structure with the copper foil wiring of the device sub-board directly below the flashlight, or other positions, as long as it is within the preset threshold range of the flashlight, the accuracy of the collected resistance value can be guaranteed within the preset threshold range, and then the temperature of the flashlight can be accurately estimated, so as to accurately adjust the working state of the flashlight, so as to achieve the purpose of temperature regulation and ensure that the flashlight will not be damaged. Among them, the device sub-board is used to directly power the flashlight. The device sub-board can be understood as a board smaller than the main board.

[0036] In some embodiments of the present application, controlling the working state of the flash lamp based on the resistance value includes the following steps:

[0037] S201: Based on the resistance value, the temperature of the flash lamp is obtained.

[0038] In some embodiments of the present application, obtaining the temperature of the flash lamp based on the resistance value includes: obtaining the temperature of the flash lamp corresponding to the resistance value based on a corresponding relationship between a preset resistance value and a preset temperature.

[0039] In an embodiment of the present application, a correspondence between a set of preset resistance values ​​and preset temperatures is established. This correspondence is usually obtained through experimental measurement. In the experiment, a series of known temperature points are selected, and then the resistance of a specific resistor in the flash lamp at these temperature points is measured. Through this set of data, a curve between the resistance value and the temperature can be drawn, or a mathematical model can be established to describe the relationship between them. Based on this, when the resistance value is collected, the resistance value can be substituted into the preset correspondence to solve the corresponding temperature value. Among them, the preset correspondence can be linear (that is, there is a linear relationship between the resistance value and the temperature), or non-linear (such as a quadratic curve, an exponential function, etc.).

[0040] S202: When the temperature of the flash lamp meets a preset condition, a first control signal is sent to the control module, so that the control module controls the flash lamp to be in an off state, or reduces the driving current of the flash lamp.

[0041] S203: When the temperature of the flash lamp does not meet the preset condition, a second control signal is sent to the control module, so that the control module controls the flash lamp to maintain the current working state, or increases the driving current of the flash lamp.

[0042] In the embodiment of the present application, the preset condition refers to a condition indicating that the temperature of the flash lamp is too high.

[0043] In the embodiment of the present application, the first control signal is used to indicate that the temperature of the flash lamp meets the preset condition. The second control signal is used to indicate that the temperature of the flash lamp does not meet the preset condition.

[0044] In some embodiments of the present application, the preset condition includes: the temperature of the flash lamp is greater than a preset temperature threshold.

[0045] The preset temperature threshold may be understood as the maximum temperature value that the flash lamp can withstand.

[0046] In the embodiment of the present application, when the temperature of the flash lamp meets the preset condition, it means that the temperature of the flash lamp is too high. If the temperature of the flash lamp continues to rise, the flash lamp will be damaged. Therefore, the drive current can be directly set to zero to control the flash lamp to be in an off state, or the current drive current of the flash lamp can be reduced to reduce the brightness of the flash lamp and gradually reduce the temperature of the flash lamp until the temperature of the flash lamp does not meet the preset condition, so that the flash lamp will not be damaged. It should be noted that the current drive current can be reduced step by step based on the preset drive current, or the current drive current can be directly reduced to the preset drive current.

[0047] Based on this, the current driving current is gradually reduced based on the preset driving current, which can avoid the sudden dimming of the light of the flash lamp due to a sudden decrease in the driving current, thereby avoiding the user's discomfort with the sudden dimming of the flash lamp.

[0048] In the embodiment of the present application, when the temperature of the flash lamp does not meet the preset condition, it means that the temperature of the flash lamp is within the safe temperature range, and therefore, the flash lamp can be controlled to maintain the current working state with the current driving current, or the current driving current can be increased to the first driving current to control the flash lamp to be in the on state and increase the brightness of the flash lamp. It should be noted that the current driving current can be increased step by step to the first driving current based on the preset driving current, or the current driving current can be directly jumped to the first driving current.

[0049] Based on this, by gradually increasing the current driving current based on the preset driving current, it is possible to avoid a sudden increase in the driving current causing the light of the flash to suddenly become brighter, thereby avoiding the user's discomfort with the sudden brightness of the flash.

[0050] In an embodiment of the present application, when the temperature of the flash does not meet the preset conditions, a second control signal is sent to the control module, so that when the control module detects that the working mode of the flash is the flashlight mode, the flash is controlled to be in a constant state; or, when the control module detects that the working mode of the flash is the fill light mode, the flash is controlled to be in a constant state; or, when the control module detects that the working mode of the flash is the flash mode, the flash is controlled to be in a flash state.

[0051] In some embodiments of the present application, different operating modes of the flash lamp correspond to different reduction operations or increase operations of the driving current of the flash lamp.

[0052] Exemplarily, when the temperature of the flashlight meets the preset conditions and the working mode of the flashlight is the flashlight mode, the driving current of the flashlight is reduced to the first driving current. When the temperature of the flashlight meets the preset conditions and the working mode of the flashlight is the fill light mode, the driving current of the flashlight is reduced to the second driving current. When the temperature of the flashlight meets the preset conditions and the working mode of the flashlight is the fill light mode, the driving current of the flashlight is reduced to the third driving current. The first driving current is greater than the second driving current, and the second driving current is greater than the third driving current.

[0053] Exemplarily, when the temperature of the flash does not meet the preset conditions and the working mode of the flash is the flashlight mode, the driving current of the flash is increased to the fourth driving current. When the temperature of the flash does not meet the preset conditions and the working mode of the flash is the fill light mode, the driving current of the flash is increased to the fifth driving current. When the temperature of the flash does not meet the preset conditions and the working mode of the flash is the fill light mode, the driving current of the flash is increased to the sixth driving current. Among them, the fourth driving current is greater than the fifth driving current, and the fifth driving current is greater than the sixth driving current.

[0054] In some embodiments of the present application, the method further includes:

[0055] When the temperature of the flash lamp meets a preset condition, a prompt message is output, where the prompt message is used to prompt a user that the current temperature of the flash lamp is too high.

[0056] Based on this, users can choose to turn off the flash on their own.

[0057] In some embodiments of the present application, obtaining the resistance value collected by the thin film temperature sensor includes: when it is detected that the flash is turned on, obtaining the resistance value collected by the thin film temperature sensor at a preset time interval.

[0058] In the embodiment of the present application, when the flashlight is turned on, the temperature of the flashlight will continue to rise as time goes by. If this situation continues for a long time, it is easy to cause certain damage to the flashlight. However, the present application can monitor the temperature of the flashlight using the resistance value collected by the thin film temperature sensor after detecting that the flashlight is turned on, that is, the temperature of the flashlight is obtained every preset time interval, so that when the temperature of the flashlight meets the preset conditions, the driving current of the flashlight can be reduced, thereby reducing the temperature of the flashlight and extending the service life of the flashlight.

[0059] In some embodiments of the present application, the resistance value collected by the thin film temperature sensor is obtained according to a preset time interval, including: obtaining the resistance values ​​collected by multiple thin film temperature sensors according to the preset time interval; and taking the average value of the multiple resistance values ​​as the resistance value corresponding to the flash.

[0060] In an embodiment of the present application, multiple thin-film temperature sensors are used to collect resistance values, and the average value of the resistance values ​​collected by each thin-film temperature sensor is calculated, so that the temperature of the flash lamp is determined based on the average value, so that the detected temperature change of the flash lamp will be more accurate, thereby achieving better temperature control of the flash lamp.

[0061] Based on the above embodiments, the present application specifically illustrates a method for controlling a flashlight. Figure 3 The process diagram of the flash control method in the embodiment of the present application is as follows Figure 3 The thin film temperature sensor may be a thin film thermistor, which is usually within 500 nm in thickness. The thin film thermistor is made into an FPC and directly attached to the inner or outer surface of the flash. The flash is connected to the device mainboard through the FPC, and the device mainboard is used to power the flash through the FPC.

[0062] like Figure 3 As shown, the control method of the flash lamp includes the following steps:

[0063] S301: Collect resistance values ​​in real time through thin film thermistors.

[0064] S302: Obtaining the resistance value collected by the thin film thermistor in real time through the main control module.

[0065] S303: Determine, by the main control module, the temperature of the flash lamp corresponding to the acquired resistance value based on the corresponding relationship between the preset resistance value and the preset temperature.

[0066] In an embodiment of the present application, a correspondence between a set of preset resistance values ​​and preset temperatures is established. This correspondence is usually obtained through experimental measurement. In the experiment, a series of known temperature points are selected, and then the resistance of a specific resistor in the flash lamp at these temperature points is measured. Through this set of data, a curve between the resistance value and the temperature can be drawn, or a mathematical model can be established to describe the relationship between them. Based on this, when the resistance value is collected, the resistance value can be substituted into the preset correspondence to solve the corresponding temperature value. Among them, the preset correspondence can be linear (that is, there is a linear relationship between the resistance value and the temperature), or non-linear (such as a quadratic curve, an exponential function, etc.).

[0067] S304: Determine, by the main control module, whether the temperature of the flash lamp exceeds a preset temperature threshold.

[0068] If it is determined that the temperature of the flash lamp exceeds the preset temperature threshold, S305 is executed; if it is determined that the temperature of the flash lamp does not exceed the preset temperature threshold, S307 is executed.

[0069] The preset temperature threshold may be understood as the maximum temperature value that the flash lamp can withstand.

[0070] In the embodiment of the present application, when the main control module determines that the temperature of the flash lamp exceeds the preset temperature threshold, it means that the temperature of the flash lamp is too high. If the temperature of the flash lamp continues to rise, the flash lamp will be damaged. Therefore, S305 to S306 are executed to achieve the purpose of reducing the temperature of the flash lamp. When the main control module determines that the temperature of the flash lamp does not exceed the preset temperature threshold, it means that the temperature of the flash lamp is within the safe temperature range. Therefore, S307 to S308 are executed to control the flash lamp to maintain the current working state, or the brightness of the flash lamp can be increased.

[0071] S305: Send a first control signal to the regulation module through the main control module.

[0072] The first control signal is used to indicate that the temperature of the flash lamp exceeds a preset temperature threshold.

[0073] The main control module is electrically connected to the thin film thermistor and the control module, and the control module is arranged outside the flash lamp.

[0074] S306: Control the flashlight to be in an off state or reduce the driving current of the flashlight through the control module.

[0075] In the embodiment of the present application, when it is determined that the temperature of the flash lamp exceeds the preset temperature threshold, it means that the temperature of the flash lamp is too high. If the temperature of the flash lamp continues to rise, the flash lamp will be damaged. Therefore, the main control module sends a first control signal to the control module to control the flash lamp to be in an off state, or reduce the driving current of the flash lamp so that the temperature of the flash lamp decreases, thereby ensuring that the flash lamp will not be damaged. It should be noted that the current driving current can be reduced step by step based on the preset driving current, or the current driving current can be directly reduced to the preset driving current.

[0076] S307: Send a second control signal to the regulation module through the main control module.

[0077] The second control signal is used to indicate that the temperature of the flash lamp does not exceed a preset temperature threshold.

[0078] S308: Control the flash lamp to maintain the current working state through the control module, or increase the driving current of the flash lamp.

[0079] In the embodiment of the present application, when it is determined that the temperature of the flash lamp does not exceed the preset temperature threshold, it means that the temperature of the flash lamp is within the safe temperature range. Therefore, by sending a second control signal to the control module through the main control module, the flash lamp can be controlled to maintain the current working state with the current drive current, or the current drive current can be increased to the first drive current to control the flash lamp to be in the on state and increase the brightness of the flash lamp. It should be noted that the current drive current can be increased step by step to the first drive current based on the preset drive current, or the current drive current can be directly jumped to the first drive current.

[0080] In an embodiment of the present application, when the temperature of the flash does not meet the preset conditions, a second control signal is sent to the control module, so that when the control module detects that the working mode of the flash is the flashlight mode, the flash is controlled to be in a constant state; or, when the control module detects that the working mode of the flash is the fill light mode, the flash is controlled to be in a constant state; or, when the control module detects that the working mode of the flash is the flash mode, the flash is controlled to be in a flash state.

[0081] In the embodiment of the present application, by integrating a thin film thermistor on the inner surface or outer surface of the flash, the heat transfer resistance between the thin film thermistor and the flash is greatly reduced, and the error between the temperature corresponding to the resistance value collected by the thin film thermistor and the actual working temperature of the flash is greatly reduced. The collected temperature data of the flash can be followed in real time to control the working state of the flash, and the working temperature of the flash can be ensured to be within an appropriate temperature range, thereby increasing the self-protection function of the electronic equipment, avoiding affecting the temperature rise performance of the electronic product, and improving the user's comfort experience.

In this way, the temperature of the flash lamp can be accurately estimated based on the resistance value collected by the thin film temperature sensor, thereby accurately adjusting the working state of the flash lamp to achieve the purpose of temperature regulation.

[0093] The control module 403 is further used to control the flash to be in an on state, or to control the driving current of the flash to be a second driving current; wherein the second driving current is greater than the first driving current.

[0094] In some embodiments of the present application, the main control module 402 is further configured to obtain the temperature of the flash lamp corresponding to the resistance value based on a corresponding relationship between a preset resistance value and a preset temperature.
