[0027] Example 1

[0028] According to an embodiment of the present invention, an embodiment of a method for adjusting illumination value is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Figure 1 is a flow chart of a method for adjusting illumination value according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0030] Step S102, obtaining a collected light illuminance value of a predetermined plane, wherein the predetermined plane is a plane that can be illuminated by the lighting module;

[0031] In step S102 provided in the present application, it is explained to obtain the collected light illuminance value of a predetermined plane, wherein the predetermined plane is a plane that can be illuminated by the lighting module.

[0032] First, the system to which the method of the present application is applied is introduced.

[0033] The method of the present application is applied to an illuminance value adjustment system, which includes: a controller, a motor, and a lighting module, wherein the lighting module includes an illuminance value sensor, the controller is connected to the motor, and the controller is connected to the lighting module. The controller is used to obtain the light illuminance value collected by the illuminance value sensor for a predetermined plane, and when the collected light illuminance value is less than a predetermined light illuminance value, control the motor to drive the lighting module to adjust the position of the lighting plane until the difference between the light illuminance value corresponding to the predetermined plane and the predetermined light illuminance value is less than a first threshold value.

[0034] Therefore, it can be known that the application scenario of the illuminance value adjustment system provided in the present application is that the lighting module illuminates a predetermined plane, and by adjusting the distance between the lighting plane and the predetermined plane, the difference between the illuminance value of the predetermined plane and the predetermined illuminance value is less than the first threshold.

[0035] It can be seen that the lighting plane is a plane that emits light, such as the light-emitting plane of a lamp, and the predetermined plane is a plane illuminated by the lighting module, such as a desktop, the ground, and the like.

[0036] It should be noted that the predetermined plane can be customized according to the actual application and scenario. For example, the predetermined plane can be the plane of area A. Assuming that the lighting plane now illuminates area B, the illumination module can be moved to the top or other position where it can illuminate the plane of area A to illuminate the plane of area A so that the plane of area A can nearly reach the predetermined illumination value.

[0037] Step S104, when the collected illuminance value is less than the predetermined illuminance value, control the motor to drive the lighting module to adjust the position of the lighting plane until the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than a first threshold, wherein the lighting plane is the plane in the lighting module that emits light.

[0038] In step S104 provided in the present application, it is explained that when the collected illuminance value is less than the predetermined illuminance value, the motor-driven lighting module can be controlled to adjust the position of the lighting plane until the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than the first threshold value, that is, the illuminance value of the lighting plane is close to the predetermined illuminance value. By adjusting the distance and position between the predetermined plane and the lighting plane so that the predetermined plane reaches a higher illuminance value, the problem of additional power consumption caused by increasing the lighting power of the lighting plane is avoided.

[0039] The predetermined illumination value may be set by the user himself or according to the environment, and may be customized according to the actual application and scenario.

[0040] It should be noted that a position adjustment limit range may also be set. When the brightness value of the predetermined plane cannot reach the predetermined illuminance value within the position adjustment limit range, the brightness of the lighting module may be increased to reach the predetermined illuminance value.

[0041] Through the above steps S102-S104, the collected light illuminance value of the predetermined plane is obtained, wherein the predetermined plane is a plane that can be illuminated by the lighting module. In the case where the collected light illuminance value is less than the predetermined light illuminance value, the motor is controlled to drive the lighting module to adjust the position of the lighting plane until the difference between the light illuminance value corresponding to the predetermined plane and the predetermined light illuminance value is less than the first threshold, wherein the lighting plane is a plane that emits light in the lighting module. It can be seen that the method provided in the embodiment of the present invention adjusts the distance between the predetermined plane and the lighting plane so that the predetermined plane reaches a higher illuminance value, thereby avoiding the additional power consumption caused by increasing the lighting power of the lighting plane, thereby solving the technical problem in the related art that additional power consumption will be generated when the illuminance value of the predetermined plane is increased.

[0042] As an optional embodiment, when the collected light illuminance value is less than a predetermined light illuminance value, controlling the motor to drive the lighting module includes: when the collected light illuminance value is less than the predetermined light illuminance value, determining a target difference between the collected light illuminance value and the predetermined light illuminance value; determining a predetermined adjustment position based on the target difference; controlling the motor to drive the lighting module to adjust to the predetermined adjustment position so that the difference between the light illuminance value corresponding to the predetermined plane and the predetermined light illuminance value is less than a first threshold value.

[0043] In this embodiment, a specific way of adjusting the position of the lighting plane is described. That is, when the collected illuminance value is less than the predetermined illuminance value, the target difference between the collected illuminance value and the predetermined illuminance value can be determined first, that is, how much difference is needed to achieve the target desired illuminance value.

[0044] Then, the predetermined adjustment position is determined based on the target difference. At this time, the predetermined adjustment position can be determined in a variety of ways. For example, the comparison relationship between the difference and the adjustment position can be retrieved to determine the adjustment position corresponding to the target difference according to the comparison relationship. Then, fast and convenient regulation can be achieved. At this time, the adjustment position corresponding to the target difference can also be calculated based on the predetermined formula and the lighting module and the relevant data of the predetermined plane. Then, precise regulation can be achieved. The predetermined adjustment position can also be determined in other ways, and customized settings can be made according to actual applications and scenarios.

[0045] It should be noted that, in the case where the predetermined plane is not the plane illuminated by the current lighting module, the position of the lighting plane can be moved first so that the lighting plane illuminates the predetermined plane. Then the height of the lighting module is adjusted so that the predetermined plane reaches the corresponding illumination value. That is, the motor is controlled to drive the lighting module to adjust to the predetermined adjustment position so that the difference between the illumination value corresponding to the predetermined plane and the predetermined illumination value is less than the first threshold value. The target illumination effect is achieved.

[0046] As an optional embodiment, when the collected illuminance value is less than a predetermined illuminance value, controlling the motor to drive the lighting module includes: when the collected illuminance value is less than the predetermined illuminance value, determining a predetermined direction and a predetermined speed for adjusting the lighting plane; controlling the motor to drive the lighting module to move the lighting plane in a predetermined direction at a predetermined speed; during the movement, collecting the illuminance value of the predetermined plane at a predetermined period until the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than a first threshold value, and controlling the motor to stop driving the lighting module.

[0047] In this embodiment, another specific way of adjusting the position of the lighting plane is described, that is, when the collected light illuminance value is less than the predetermined light illuminance value, the predetermined direction and predetermined speed of adjusting the lighting plane can be determined.

[0048] For the predetermined direction, for example, when the illumination plane moves toward the direction of the predetermined plane, when the predetermined plane is directly below the illumination plane, the illumination plane moves directly downward.

[0049] For the predetermined speed, the predetermined speed can be determined according to the difference. For example, when the difference is large, a higher speed can be set, and when the difference is small, a lower speed can be set, so as to achieve precise control.

[0050] The motor is controlled to drive the lighting module to move the lighting plane in a predetermined direction at a predetermined speed. During the movement, the illuminance value of the predetermined plane is collected at a predetermined period. The predetermined period can be customized based on actual experience and scenes, and can also be set according to the difference and speed. For example, when the difference is large and the speed is small, the period can be set larger. When the difference is small and the speed is large, the period can be set smaller to achieve precise adjustment.

[0051] Until the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than the first threshold, the control motor stops driving the lighting module, that is, it is considered that the lighting plane has reached a suitable position and can make the predetermined plane reach the desired brightness value.

[0052] As an optional embodiment, when the collected illuminance value is less than a predetermined illuminance value, before controlling the motor to drive the lighting module, it also includes: determining a target environment for using the lighting module; determining a standard power corresponding to the target environment, and a real-time power corresponding to the target environment; and determining a predetermined illuminance value based on the standard power and the real-time power.

[0053] In this embodiment, the process of presetting the illuminance value is described. Since the problem solved by the method provided in this application is the problem of excessive power consumption, the existing power value in the environment can be determined by environment as a unit, so as to determine the predetermined illuminance value according to the existing power value.

[0054] That is, when the collected illuminance value is less than the predetermined illuminance value, before controlling the motor to drive the lighting module, the target environment for using the lighting module is determined, such as a residential environment or an office environment.

[0055] Determine the standard power corresponding to the target environment, such as the corresponding limited power in the residential environment, the limited power corresponding to the office environment, and the real-time power corresponding to the target environment, such as the corresponding real-time power in the residential environment, and the real-time power corresponding to the office environment. Determine the predetermined illuminance value based on the standard power and the real-time power. For example, when the real-time power is much less than the limited power or the standard power, a higher predetermined illuminance value can be set. So that the overall environment does not produce excessive power consumption. When the real-time power is close to the limited power or the standard power, a higher predetermined illuminance value can be set to avoid the power in the overall environment exceeding the limit of the limited power or the standard power, resulting in additional consumption. Moreover, the method provided in the present application can also enable the predetermined plane to reach the predetermined illumination value when the power in the overall environment does not exceed the limit of the limited power or the standard power, thereby achieving the technical effect of balancing lighting and power consumption.

[0056] As an optional embodiment, after obtaining the collected illuminance value of the predetermined plane, it also includes: obtaining the expected illuminance value of the predetermined plane; when the difference between the collected illuminance value and the expected illuminance value is greater than or equal to a second threshold, determining the size relationship between the expected illuminance value and the predetermined illuminance value; when the size relationship is that the expected illuminance value is less than or equal to the predetermined illuminance value, controlling the motor to drive the lighting module to adjust the position of the lighting plane until the difference between the illuminance value corresponding to the predetermined plane and the expected illuminance value is less than the second threshold.

[0057] In this embodiment, a case where an expected illuminance value is involved is described. In this case, the expected illuminance value is the illuminance value expected by the user, and the predetermined illuminance value is a limit or standard illuminance value. In this case, the expected illuminance value of the predetermined plane can be obtained, wherein the expected illuminance value can be the illuminance value set or expected by the user, and can be set by the user. When the expected illuminance value is set, the illuminance value of the predetermined plane should be to reach the expected illuminance value.

[0058] When the difference between the collected illuminance value and the expected illuminance value is greater than or equal to the second threshold, that is, when the illuminance value on the current predetermined plane is inconsistent with the expected illuminance value and the difference is large, the magnitude relationship between the expected illuminance value and the predetermined illuminance value can be determined. That is, whether the expected illuminance value is higher or the predetermined illuminance value is higher.

[0059] When the size relationship is that the expected illuminance value is less than or equal to the predetermined illuminance value, the motor is controlled to drive the lighting module to adjust the position of the lighting plane until the difference between the illuminance value corresponding to the predetermined plane and the expected illuminance value is less than a second threshold, so that the illuminance value corresponding to the predetermined plane is close to the expected illuminance value.

[0060] When the size relationship is that the expected illuminance value is greater than the predetermined illuminance value, the motor is controlled to drive the lighting module to adjust the position of the lighting plane until the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than the first threshold, so that the illuminance value corresponding to the predetermined plane is close to the predetermined illuminance value.

[0061] It should be noted that from the perspective of energy saving, in this case, it is also possible to determine whether there is an adjustable low-power device in the environment. If there is an adjustable low-power device, the power of the adjustable low-power device can be reduced to increase the predetermined illuminance value, thereby making the predetermined illuminance value close to the expected illuminance value, thereby adjusting the illuminance value of the predetermined plane to the expected illuminance value.

[0062] As an optional embodiment, after obtaining the collected illuminance value of the predetermined plane, it also includes: when the collected illuminance value is greater than the predetermined illuminance value, controlling the luminous power of the power module in the lighting module so that the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than a first threshold.

[0063] In this embodiment, the operation after obtaining the collected illuminance value of the predetermined plane is described. When the collected illuminance value is greater than the predetermined illuminance value, the luminous power of the power module in the lighting module is controlled so that the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than the first threshold value. That is, when the predetermined illuminance value is small, the power consumption can be reduced by directly lowering the luminous power of the lighting module.

[0064] As an optional embodiment, after obtaining the collected illuminance value of the predetermined plane, it also includes: when the collected illuminance value is less than the predetermined illuminance value, determining the movement restriction result corresponding to the lighting module; when the movement restriction result is to restrict the movement, controlling the luminous power of the power supply module in the lighting module so that the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than a first threshold value.

[0065] In this embodiment, another adjustment situation is described when the collected illuminance value is less than the predetermined illuminance value. At this time, it can be determined whether the lighting module can be moved, that is, the movement restriction result is determined. The movement restriction result can be set by the user. For example, if the user does not want to change the lighting height, the movement restriction result is to restrict the movement. In this case, the luminous power of the power module in the lighting module is controlled so that the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than the first threshold value, so as to achieve the lighting effect expected by the user while meeting the user's requirements.

[0066] As an optional embodiment, after obtaining the collected illuminance value of the predetermined plane, it also includes: when the collected illuminance value is less than the predetermined illuminance value, determining the movement limit distance corresponding to the lighting module, wherein the movement limit distance is the distance that the lighting module can move, and the movement of the lighting module cannot exceed the movement limit distance; controlling the motor to drive the lighting module to move, and stopping the movement when the target condition is met, wherein the target condition includes a first sub-condition and a second sub-condition, the first sub-condition being that the lighting module moves to the movement limit distance, and the second sub-condition being that the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than a first threshold value; when the target condition reached is the first sub-condition, controlling the luminous power of the power supply module in the lighting module so that the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than the first threshold value.

[0067] In this embodiment, another adjustment situation is described when the collected illuminance value is less than the predetermined illuminance value. At this time, the movement limit distance corresponding to the lighting module can be determined, that is, the movable distance of the lighting module can be determined, and the distance that the lighting plane can move in the direction of the predetermined plane can be determined, and the movement of the lighting module cannot exceed the movement limit distance. Because the lighting module cannot be infinitely movable, it is set to move. If it still cannot meet the lighting requirements after moving to the movement limit distance, the luminous power of the power module in the lighting module is controlled so that the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than the first threshold.

[0068] That is, in the above process, the motor is controlled to drive the lighting module to move, and the movement is stopped when the target condition is reached, wherein the target condition includes a first sub-condition and a second sub-condition, that is, the movement is stopped when the first sub-condition that the lighting module moves to the movement limit distance is reached, or the movement is stopped when the difference between the illuminance value corresponding to the predetermined plane and the predetermined illuminance value is less than the first threshold value and the lighting requirement is met. When the first sub-condition is met, the lighting is further controlled by adjusting the lighting setting to meet the lighting requirement. In this way, the movement distance limit is taken into account, and the purpose of still being able to meet the lighting requirement is achieved when there is a movement distance limit.

[0069] As an optional embodiment, the movement limit distance is determined according to a target parameter, and the target parameter includes at least one of the following: a lighting mode parameter, a lighting device parameter, and a lighting scene parameter.

[0070] In this embodiment, the process of determining the movement limit distance is described, wherein the movement limit distance may be determined based on one or more parameters. In this embodiment, lighting mode parameters, lighting device parameters, and lighting scene parameters are introduced.

[0071] Among them, the lighting mode parameters can be parameters for the lifting and lowering range of the lighting module in different modes. For example, in normal mode, the minimum distance from the ground for the lighting plane to descend is not less than 2 meters; in learning mode, the minimum distance from the ground for the lighting plane to descend is not less than 1.5 meters, etc., which can be adaptively set according to the actual mode.

[0072] The lighting device parameters may be parameters corresponding to the device / equipment including the lighting module, for example, the predetermined lifting range may be determined according to the mechanical structure of the lamp.

[0073] Among them, the lighting scene parameters can be the parameters of the lifting range of the lighting module in different scenes. For example, in the bedroom scene, the minimum distance from the ground for the lighting plane to descend is not less than 2 meters; in the study mode, the minimum distance from the ground for the lighting plane to descend is not less than 1.5 meters, etc., which can be adaptively set according to the actual scene.

[0074] It should be noted that the movement limit distance may be determined based on one or more of the above-mentioned factors, thereby making the determined movement limit distance more reasonable and accurate.

[0075] Based on the above embodiments and optional embodiments, an optional implementation is provided, which is described in detail below.

The host computer and the motor are placed in the same suspender, driving the motor through a wired connection, and communicating with the TSIM sensor data through a Bluetooth connection.

[0080] The light source in the lighting fixture is responsible for the lighting function of the target surface, and the TSIM sensor is responsible for collecting real-time illuminance data of the target illuminated surface, transmitting the data to the Bluetooth module through the I2C bus, and then the Bluetooth module transmits the data wirelessly to the host computer.

[0081] After receiving the expected light intensity value given by the user APP, the upper computer drives the motor to adjust the height between the lighting fixture and the target surface after algorithm analysis, so as to adjust the light intensity of the target surface while keeping the light source intensity unchanged.

[0082] The illumination value adjustment method provided in the optional embodiment of the present invention is as follows:

[0083] The S2 lighting fixture is suspended directly above the target irradiation surface.

[0084] It should be noted that the illuminance data detected by the TSIM sensor used in the optional implementation mode of the present invention has nothing to do with the distance, and the illuminance data detected at each distance are the same. The TSIM sensor sends the target surface illuminance data to the host computer every 0.1s.

[0085] S2 users can set the expected value of the target surface illumination through the APP, and can also read the current target surface illumination value.

[0086] After the host computer at S3 obtains the real-time illuminance lux0 of the target surface transmitted by TSIM and the expected illuminance lux1 of the target surface, it compares the values of lux0 and lux1:

[0087] When lux0 < lux1, the host computer controls the motor to rotate, moves the lighting fixture downward, shortens the distance between the lighting fixture and the target surface, and increases the illuminance of the target surface under the condition that the illuminance emitted by the light source remains constant.

[0088] The height change of the lighting fixture needs to be slow, and the speed is controlled at 0.1 m / s. The host computer can obtain the illuminance data at a speed of 0.1 second / time, achieve real-time linear adjustment of the illuminance of the target surface, and stop the height change of the lighting fixture in time when the target surface reaches the expected illuminance lux1.

[0089] When lux0 > lux1, the host computer adjusts the illuminance of the light source in the lighting fixture to be lower, and compares the data of lux0 and lux1 in real time until the two data are equal.

[0090] S4 Since the height adjustment of the lighting fixture has a range limit, the range of illuminance values that the lighting fixture can reach is restricted in the user APP.

[0091] Furthermore, in step S2, the user can also mark the relative position and shape of the target surface according to the picture feedback by the host computer. It is used to more accurately obtain the illuminance of the target surface. That is, the target surface can be a specially selected area by the user so that the specially selected area reaches the expected brightness.

[0092] Furthermore, in step S3, the sensor continuously obtains the illuminance value of the target surface selected by the user and stops when it approaches the preset lux value.

[0093] Furthermore, in step S3, when the lamp is descending in real time, by continuously obtaining the change value of the illuminance of the target surface, a relationship graph between the illuminance change and the descending distance is formed. When it is greater than the expected preset value, it stops, and adjusts the light to the expected preset value;

[0094] Furthermore, in step S4, when the height of the lighting fixture is adjusted within its adjustment range and the preset illuminance value is not reached, the illuminance value of the light is increased.

[0095] Furthermore, the range of illuminance values that the lighting fixture can reach can be restricted in the user APP, or can be set according to one or more of the lighting mode parameters, lighting device parameters, and lighting scene parameters.

[0096] Furthermore, the adjustment limit can also be set that the target surface feedback by the sensor has exceeded the irradiation range.

[0097] Further, the adjustment limit may set a limit range on the adjustment mechanism of the lamp.

[0098] Through the above optional implementation, at least the following beneficial effects can be achieved:

[0099] The illumination of the target surface can be adjusted while keeping the power consumption of the whole device basically unchanged. Compared with the existing method of adjusting the illumination of the light source, the purpose of energy saving can be achieved without additionally increasing the power of the light source in the scene where the illumination needs to be increased.
