Description

Technical Field

[0001] The present application relates to the technical field of light source dimming, and in particular to a test system for controlling light source dimming. Background Art

[0002] As domestic optical laboratories have increasingly stringent requirements for light source dimming control, traditional manual dimming is no longer suitable for current testing requirements. In the existing technology, the traditional manual dimming process specifically includes the following steps:

[0003] Plug in the power cord and data cable of the light source and illuminometer, turn on the power switches of the light source and illuminometer, and fix the illuminometer at a designated position directly in front of the center of the plane of the light source;

[0004] The test engineer manually turns on the light switch of the light source and uses the buttons on the light source control panel to adjust the light source to the maximum illumination value, allowing the light source to preheat for about 3-5 minutes to reach the optimal working state;

[0005] The test engineer first manually adjusts the light source to a certain illuminance level. At this time, the test engineer observes the illuminance value displayed on the illuminance meter with the naked eye. If the illuminance value currently displayed by the illuminance meter is less than the target illuminance value, the test engineer continues to manually increase the illuminance level of the light source until the illuminance level of the light source reaches a certain illuminance value, and the illuminance value currently displayed by the illuminance meter is very close to the target illuminance value; if the illuminance value currently displayed by the illuminance meter is greater than the target illuminance value, the test engineer continues to manually decrease the illuminance level of the light source until the illuminance level of the light source reaches a certain value, and the illuminance value currently displayed by the illuminance meter is very close to the target illuminance value;

[0006] By moving the position of the illuminance meter, changing the distance between the illuminance meter and the light source, and repeating the steps of adjusting the illuminance value to a certain illuminance level for illuminance value testing, the relationship between the target illuminance value and the illuminance level of the light source at different distance values ​​can be obtained.

[0007] In the existing technology, if the test engineer in the optical laboratory wants to achieve a certain ideal illuminance value at a certain position directly in front of the light source, he can only go through a set of tedious and complicated manual adjustments to the light source illuminance level, and then read the current displayed illuminance value with the naked eye for comparison. On the one hand, it increases the workload of the engineer and reduces the debugging efficiency. On the other hand, a series of inevitable errors are inevitable during the test process, such as inaccurate illuminance value display of the illuminance meter, human interference that may cause light reflection, etc., and repeatability is also a problem. Manual dimming cannot ensure that the test environment is the same every time, which adds many uncertain interference factors. Summary of the Invention

[0029] The present application is described in further detail below with reference to the accompanying drawings.

[0030] One aspect of the present application provides a test system for controlling light source dimming, wherein the system includes a light source and an illuminometer, and wherein the system includes the following test steps:

[0031] Step 1: respectively turning on the power switches of the light source and the illuminometer, and moving and fixing the illuminometer at a preset position away from the center of the plane of the light source;

[0032] Step 2: Control the light switch to turn on the light source, adjust the light intensity of the light source to the maximum illumination value, and preheat the light source for a preset time at the maximum illumination value to achieve the optimal working state of the light source; the preset time includes but is not limited to 3 minutes, 5 minutes or other time lengths.

[0033] Step 3: Controlling the illumination intensity of the light source to sequentially output preset illumination values ​​corresponding to illumination levels of 0 to 255. At the same time, the illuminance meter obtains the actual illumination value of the light source at each illumination level, and generates a calibration file corresponding to the current distance between the illuminance meter and the light source, wherein the calibration file includes a mapping relationship between different illumination levels of the light source and the actual illumination values ​​corresponding to the different illumination levels of the illuminance meter;

[0034] Step 4: Control the movement position of the illuminometer, change the distance between the illuminometer and the light source, and repeat step 3 to obtain calibration files corresponding to different distances between the illuminometer and the light source;

[0035] Step 5. Obtain the target illuminance value in the actual test environment, and obtain the real-time distance between the illuminance meter and the light source in the actual test environment. After matching the target calibration file corresponding to the real-time distance from the calibration files corresponding to the obtained different distances, automatically adjust the real-time illuminance level of the light source based on the target calibration file to achieve the target illuminance value.

[0036] In this embodiment, Figure 1 As shown, one aspect of the present application proposes a test system for controlling light source dimming, which is mainly developed for the precise adjustment of the illumination of the light source in the optical laboratory. The user only needs to place the illuminance meter and the light source in the right position, and the illumination calibration and adjustment will be automatically performed. There is no need for manual intervention and manual adjustment of the light source illumination. The specific test steps for controlling light source dimming are as follows:

[0037] Plug in the power cord and data cable of the light source and illuminometer, turn on the power switches of the light source and illuminometer respectively, and fix the illuminometer at a preset position directly in front of the plane center of the light source. The preset position includes but is not limited to any length such as one meter, two meters and three meters between the light source and the illuminometer.

[0038] Automatically turn on the light switch of the light source, adjust the light source to the maximum illumination value, and let the light source preheat for about 4 minutes to make the light source reach the best working state.

[0039] The light source is controlled to automatically print out preset illuminance values ​​corresponding to 0 to 255 illuminance levels in sequence. At the same time, the illuminance meter automatically obtains the actual illuminance value of the light source at each illuminance level, and automatically generates a calibration file in CSV format according to a preset naming rule as a calibration file corresponding to the current distance between the illuminance meter and the light source. The calibration file includes a mapping relationship between different illuminance levels of the light source and the actual illuminance values ​​corresponding to the illuminance meter at different illuminance levels, that is, one illuminance level corresponds to one actual illuminance value. The calibration file also includes the device type of the light source, the device type of the illuminance meter, and the current distance between the illuminance meter and the light source.

[0040] Control the position of the mobile illuminance meter, change the distance between the illuminance meter and the light source, repeat the above steps to generate a calibration file, and generate a calibration file corresponding to different distances between the illuminance meter and the light source, that is, each distance between the illuminance meter and the light source corresponds to a calibration file.

[0041] In actual application scenarios, the target illuminance value that you want to achieve in the actual test environment is obtained. The target illuminance value can be obtained by input from a test engineer or from a third-party server that controls the illuminance value. At the same time, it is also necessary to obtain the real-time distance between the illuminance meter and the light source in the actual test environment, and export the target calibration file corresponding to the real-time distance from the calibration files corresponding to different distances. Here, the initial light source illuminance level can be found according to the imported target calibration file, which greatly reduces the automatic dimming time. The real-time illuminance level of the light source is automatically adjusted based on the target calibration file corresponding to the real-time distance so that the light intensity emitted by the light source can meet the target illuminance value, which not only saves the test engineer's time for manual adjustment, but also improves the test efficiency of the adjustment.

[0042] Following the above embodiment of the present application, in order not to affect the calibration efficiency and user experience, the step 3 of generating the calibration file corresponding to the current distance between the illuminometer and the light source specifically includes:

[0043] A calibration file corresponding to the current distance between the illuminometer and the light source is generated within a preset time interval. The preset time interval includes, but is not limited to, thirty seconds, half a minute, one minute, two minutes, three minutes, four minutes, five minutes, or even shorter times. The total time required to generate the calibration file corresponding to the current distance between the illuminometer and the light source must be within the preset time interval, and the calibration time required to generate the calibration file should not be too long to avoid affecting calibration efficiency and user experience.

[0044] Following the above embodiment of the present application, in step 3, the light intensity of the light source is controlled to sequentially output preset illuminance values ​​corresponding to 0 to 255 illuminance levels. At the same time, the illuminance meter obtains the actual illuminance value of the light source at each illuminance level, specifically including:

[0045] According to the preset adjustment frequency, the light intensity of the light source is controlled to hit the preset illumination values ​​corresponding to the illumination levels of 0 to 255 in sequence, while the illuminance meter respectively obtains the actual illumination value of the light source at each illumination level. Here, when controlling the light intensity of the light source to hit different illumination levels in sequence, the frequency of adjusting the illumination level of the light source should not be too fast, that is, a preset adjustment frequency is required and the preset adjustment frequency should not be too large. For example, in a preferred embodiment of the present application, the average value of the reading value 5 times can be used as the current actual illumination value, and the interval between each of the 5 times is not less than 1 second (because the illuminance meter takes tens of seconds to test the low illumination level once). According to the deviation between the actual illumination value and the illumination value to be achieved, the illumination level of the light source is adjusted, and the level step value of the illumination level of the light source can be calculated from the calibration file.

[0046] Following the above embodiment of the present application, in step 5, while obtaining the target illuminance value in the actual test environment, step 5 also obtains the illuminance value fluctuation threshold in the actual test environment.

[0047] The step of matching a target calibration file corresponding to the real-time spacing from the obtained calibration files corresponding to different spacings includes:

[0048] Based on the target illuminance value and the illuminance value fluctuation threshold, obtaining a target fluctuation range corresponding to the target illuminance value;

[0049] Based on the target fluctuation range, a target calibration file corresponding to the real-time spacing is matched from the obtained calibration files corresponding to different spacings.

[0050] In a preferred embodiment of the present application, if the target illuminance value is 1000 and the illuminance value fluctuation threshold is 2%, according to the target illuminance value: 1000 and the illuminance value fluctuation threshold: 2%, it can be calculated that when the target illuminance value is determined, the target fluctuation range of the acceptable illuminance value is illuminance values ​​980~1020, and then according to the target fluctuation range: illuminance values ​​980~1020, the target calibration file corresponding to the real-time spacing is matched from the calibration files corresponding to the obtained different spacings.

[0051] In the embodiments of the present application, in order to overcome the various problems existing in the prior art, the present application provides a test system for controlling the dimming of a light source. After the test engineer has set up the corresponding test environment, he can start the entire test system and do other things. The entire dimming calibration process is automatically completed by the light source and the illuminance meter, without any disorderly human intervention in the middle. After the dimming is completed, it is only necessary to obtain the target illuminance value to be hit, and the entire test system will calculate and generate the required target illuminance value internally. At the same time, it has excellent repeatability, a stable test environment, high equipment precision, and efficient and reliable data, which can greatly improve the work efficiency of test engineers, reduce a lot of working time, and liberate engineers from heavy physical and mental labor. The data is also reliable and convincing.

[0052] In summary, the embodiment of the present application provides a test system for controlling the dimming of a light source, which includes a light source and an illuminance meter, wherein the system includes the following test steps: step 1, respectively controlling the power switches of the light source and the illuminance meter to turn on, and moving and fixing the illuminance meter at a preset position away from the center of the plane of the light source; step 2, controlling the light switch of the light source to turn on, adjusting the light intensity of the light source to a maximum illuminance value, and preheating the light source for a preset time at the maximum illuminance value to achieve the best working state of the light source; step 3, controlling the light intensity of the light source to sequentially output preset illuminance values ​​corresponding to 0 to 255 illuminance levels, and at the same time, the illuminance meter respectively obtains the actual illuminance value of the light source at each illuminance level, and generates a comparison between the illuminance meter and the illuminance meter. a calibration file corresponding to the current distance between the light sources, the calibration file including a mapping relationship between different illuminance levels of the light sources and actual illuminance values ​​corresponding to the illuminance meter at different illuminance levels; step 4, controlling the movement position of the illuminance meter, changing the distance between the illuminance meter and the light source, and repeating step 3 to obtain calibration files corresponding to different distances between the illuminance meter and the light source; step 5, obtaining a target illuminance value in an actual test environment, and obtaining a real-time distance between the illuminance meter and the light source in the actual test environment, and matching a target calibration file corresponding to the real-time distance from the obtained calibration files corresponding to the different distances, and automatically adjusting the real-time illuminance level of the light source based on the target calibration file to achieve the target illuminance value. The test engineer only needs to set up the actual test environment to be tested and obtain the desired target illuminance value. The system will automatically match the target calibration file corresponding to the target illuminance value, and based on the target calibration file, the automatic dimming test system can quickly and accurately generate the target illuminance value at different distance values, reducing the engineer's workload and test efficiency.
