Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] Figure 1 The illustration shows an implementation scenario of an automatic dimming method for a light-sensing remote control 10 according to an embodiment of this application.
[0029] See Figure 1 The first aspect of this application provides an automatic dimming method for a light-sensing remote control 10, applicable to target scenes with lighting needs such as museums, art galleries, hotels, and shopping malls. The light-sensing remote control 10 is communicatively connected to a target lighting fixture 20 within the target scene via wireless communication, which can be selected as Bluetooth. Bluetooth Communication, radio frequency remote control Radio Frequency (RF) ) communication, Zigbee Communication etc.
[0030] In the implementation scenario of Bluetooth communication, a Bluetooth network can be created first by operating the light sensor remote control 10; then, according to the dimming scenario, the corresponding target light fixture 20 can be selected to join the Bluetooth network, and there can be one or more target light fixtures 20.
[0031] In one scenario, to simplify operation and ensure consistent dimming, this method can synchronously adjust all lights connected to the Bluetooth network. Users can select to connect only the target light 20 that needs dimming, and during dimming, all lights connected to the Bluetooth network will be dimmed synchronously.
[0032] In another scenario, the target light fixture 20 connected to the Bluetooth network can be pre-set with a specific identifier, or assigned a specific identifier by the light sensor remote control 10. Different target light fixtures 20 have different specific identifiers. For example, different target light fixtures 20 may have specific identifiers A, B, C, and others, which will not be elaborated further below. When the light sensor remote control 10 dims the light, it can automatically dim the target light fixture 20 that needs dimming based on the specific identifier.
[0033] Next, fix the light sensor remote control 10 to the target position within the target area. The illumination range of the target lamp 20 corresponds to the target area. That is, the target area is the area where the illuminance value will be affected by the dimming of the target lamp 20. The target position can be determined based on prior knowledge. It can usually be selected as the position with the strongest light intensity of the target lamp 20 or the center position of the target area.
[0034] In one specific implementation scenario, the light sensor remote control 10 is set in the target area corresponding to the target lamp 20 with a specific identifier A. When dimming, the light sensor remote control 10 can select the specific identifier A and automatically dim only the target lamp 20 corresponding to the specific identifier A.
[0035] In another specific implementation scenario, when the target area is the display wall of a museum, multiple wall washer lights of the same type that are equidistantly arranged on the display wall are added to the Bluetooth network of the light sensor remote control 10. Then, the detection end of the light sensor remote control 10 is set to the brightest position or the center position of the light spot corresponding to any wall washer light. While the light sensor remote control 10 remains stable, all wall washer lights in the Bluetooth network are dimmed synchronously.
[0036] Figure 2 This illustration shows an implementation flow diagram of an automatic dimming method for a light-sensing remote control according to an embodiment of this application. Figure 1 .
[0037] Combination Figure 1 and Figure 2 The automatic dimming method for a light-sensitive remote control provided in this application includes: Operation 110 retrieves a dimming command, which instructs the target area to be dimmed to the target illuminance value. The light-sensing remote control can obtain the dimming command from the user via an operation screen, operation buttons, or a third-party control terminal. The dimming command includes the target illuminance value, which represents the illuminance value desired by the user at the target location. In scenarios requiring the selection of a specific target luminaire, the dimming command may also include a specific identifier corresponding to the target luminaire.
[0038] Operation 120 involves determining the current illuminance value of the target area and checking if it meets the target difference range corresponding to the target illuminance value. The light-sensing remote control is equipped with a light sensor, which detects the illuminance at the target location to obtain the current illuminance value. The target difference range can be determined based on the required dimming precision; the higher the required dimming precision, the smaller the corresponding target difference range can be. In one implementation scenario, the target difference range can be 0, indicating that the current illuminance value needs to be adjusted to match the target illuminance value. By judging the target difference range between the current illuminance value and the target illuminance value, it can be determined whether dimming operation is needed for the target light fixture.
[0039] Operation 130: If it is determined that the current illuminance value does not meet the target difference range corresponding to the target illuminance value, the target dimming operation and the corresponding dynamic dimming step value are determined based on the current illuminance value and the target illuminance value. That is, the current illuminance value of the target area does not meet the user's requirements, and a dimming operation is needed. The target dimming operation includes two operations: increasing the brightness of the target luminaire and decreasing the brightness of the target luminaire. The dynamic dimming step value is used to characterize the adjustable dimming value. The larger the dynamic dimming step value, the greater the dimming range of the target luminaire; conversely, the smaller the dynamic dimming step value, the smaller the dimming range of the target luminaire.
[0040] Operation 140 instructs the target luminaire to perform a target dimming operation based on a dynamic dimming step value, and returns to determine the current illuminance value of the target area. After completing one dimming operation, it returns to execute operations 120 and 130. The corresponding target dimming operation and corresponding dynamic dimming step value are then redefined in the next round. This process continues, allowing the target luminaire to automatically and quickly dim to the target illuminance value within the target difference range. The closer the luminaire is to the target illuminance value, the higher the precision of the dimming; this process can be automated.
[0041] Operation 150: If it is determined that the current illuminance value meets the target difference range corresponding to the target illuminance value, a dimming indicator is set. The dimming indicator is used to indicate that the current illuminance value meets the target difference range corresponding to the target illuminance value. The dimming indicator can be used to determine that this dimming has achieved the purpose of adjusting the current illuminance value to the target illuminance value.
[0042] Figure 3 This illustration shows an implementation flow diagram of an automatic dimming method for a light-sensing remote control according to an embodiment of this application. Figure 2 .
[0043] See Figure 3In one possible implementation, before operation 140, the method further includes: operation 210, acquiring the current brightness value and safe brightness value of the target luminaire; operation 220, determining the target brightness value based on the target illuminance value, the current illuminance value, and the current brightness value; operation 230, comparing the target brightness value with the safe brightness value to obtain a comparison result; operation 240, if the comparison result indicates that the target brightness value meets the safe brightness value, sending a dimming start command to the target luminaire; operation 250, if the comparison result indicates that the target brightness value does not meet the safe brightness value, generating a corresponding first prompt message.
[0044] To ensure that the dimming process can dim the target area to the target illuminance value, it can be determined in advance whether the target luminaire can make the illuminance value of the target area reach the target illuminance value before dimming.
[0045] In one implementation scenario of operation 210, the light-sensing remote control can obtain the current brightness value and safe brightness value of the target light fixture through a brightness query command. The safe brightness value is used to characterize the maximum brightness value of the target light fixture under normal and safe operating conditions.
[0046] In another implementation scenario of Operation 210, the light sensor remote control can pre-store the safe brightness values corresponding to various types of lamps, and the light sensor remote control can determine the corresponding safe brightness value based on the specific identifier of the target lamp connected to the Bluetooth network.
[0047] In operation 220, the target luminance value is determined based on the target illuminance value, the current illuminance value, and the current luminance value. Typically, the ratio of the target illuminance value to the current illuminance value and the ratio of the target luminance value to the current luminance value have a linear relationship. Therefore, the ratio of the target luminance value to the current luminance value can be determined based on the ratio of the target illuminance value to the current luminance value, and thus the target luminance value can be determined. This can be characterized as follows: target lux / current lux = target nit / current nit in, target lux Used to characterize target illuminance values, current lux Used to characterize the current illuminance value. target nit Used to characterize the target brightness value, current nit Used to represent the current brightness value.
[0048] Furthermore, based on external environmental and other influences, an impact factor can be set. K , K It can be determined through testing or based on prior knowledge, and can be characterized as follows: target lux / current lux = K (target nit / current nit ) In operations 230 and 240, by comparing the target brightness value with the safe brightness value, it can be determined whether the target brightness value is within the safe brightness range of the target luminaire. If the comparison result is that the target brightness value meets the safe brightness value, that is, if the target brightness value does not exceed the safe brightness value, the target area can be dimmed to the target illuminance value, and it is determined that the dimming process can be executed safely and smoothly. A dimming start command is sent to the target luminaire, which is used to enable the dimming function of the target luminaire.
[0049] Correspondingly, in operation 250, if the comparison result shows that the target brightness value does not meet the safe brightness value, that is, adjusting the target area to the target illuminance value would cause the target brightness value to exceed the safe brightness value, a corresponding first prompt message is generated. This first prompt message can be used to prompt the user to add, replace, or adjust the target lighting fixture, or modify the target brightness value.
[0050] Figure 4 This illustration shows an implementation flow diagram of an automatic dimming method for a light-sensing remote control according to an embodiment of this application. Figure 3 .
[0051] See Figure 4 In one possible implementation, operation 130 includes: operation 131, performing difference processing on the target illuminance value and the current illuminance value to determine the current illuminance difference; operation 132, determining the corresponding target dimming operation based on the sign information of the current illuminance difference; and operation 133, determining the corresponding dynamic dimming step value based on the absolute value of the current illuminance difference.
[0052] Operation 132 includes: if the sign information of the current illuminance difference is negative, determining the target dimming operation as the first adjustment operation; if the sign information of the current illuminance difference is positive, determining the target dimming operation as the second adjustment operation.
[0053] It should be noted that in operation 131, if the current illuminance difference is... △lux The calculation method is as follows: △ lux = target lux - current lux. Correspondingly, the first adjustment operation is to decrease the brightness of the target light fixture, and the second adjustment operation is to increase the brightness of the target light fixture.
[0054] Conversely, in operation 131, if the current illuminance difference is... △ lux The calculation method is as follows: △lux = current lux - target lux. Correspondingly, the first adjustment operation is to increase the brightness of the target light fixture, and the second adjustment operation is to decrease the brightness of the target light fixture.
[0055] Operation 133 includes: determining the dynamic dimming step value corresponding to the current illuminance difference based on the mapping parameter information between the absolute value and the dimming step value; wherein, the absolute value and the dimming step value are directly proportional. The mapping parameter information between the absolute value and the dimming step value can be determined based on prior knowledge and can be pre-stored in the light-sensing remote control. The mapping parameter information can be a mapping table, a mapping range, or can be obtained based on the output of a mapping model. In a specific implementation scenario, The first mapping range is set to X~2X, corresponding to a dimming step value of 0.1%; The second mapping range is set to 2X~5X, corresponding to a dimming step value of 0.5%; The third mapping range is set to 5X~10X, corresponding to a dimming step value of 1%; The fourth mapping range is set to exceed 10X, with a corresponding dimming step value of 2%.
[0056] X can be used to characterize the maximum value of the target difference range.
[0057] In actual dimming, since different target lamps require different dimming times, and the data processing time of the remote control is usually much shorter than that of the target lamp, in order to avoid the situation where the brightness of the target lamp changes after operation 150 is executed, the method of this application embodiment further includes, after operation 150: first, counting and accumulating the dimming flag, determining the current count value, and returning to execute operation 120 to determine the current illuminance value of the target area.
[0058] Similarly, in each round, based on operation 120, if operation 130 is subsequently executed, then the corresponding operation is executed. If it is determined that the current illuminance difference does not meet the target difference range corresponding to the target illuminance value, the current count value is set to zero.
[0059] If operation 150 is subsequently executed, an accumulation operation is performed accordingly. The count is accumulated until the current count value meets the target count value, at which point it is determined that the target area has been dimmed to the target illuminance value, and a corresponding second prompt message is generated. The target count value can be determined based on the data processing time of the light-sensing remote control in this method and the dimming time of a conventional target lamp. For example, in one implementation scenario, if the data processing time for each cycle of this method is Y, and the corresponding dimming time is 3Y, then the target count value can be set to a value greater than or equal to 3, such as 4 or 5.
[0060] In one possible implementation, after the accumulated count value meets the target count value, the dimming can be determined to be complete. The method further includes sending a dimming off command, which instructs the target luminaire to turn off the dimming function to ensure that the target luminaire operates stably at the current brightness.
