[0043] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0044] The main solution of the embodiment of the present application is: a light source detection method is proposed based on a light source detection device, the light source detection device includes an optical fiber, a light sensor and a condenser, the condenser is used to converge the light of the light source to be tested and incident on the optical fiber, the optical fiber is used to transmit the incident light to the light sensor, the method includes: obtaining the actual brightness detected by the light sensor; determining whether the light source to be tested is qualified according to the relationship between the actual brightness and the standard brightness.

[0045] In this embodiment, for the convenience of description, the light source detection device is used as the execution subject for explanation below.

[0046] In the prior art, generally, an ambient light sensor is placed directly in the environment where the product is located during the process of emitting light from the light source on the product, and the ambient light detected by the ambient light sensor is obtained as the actual brightness data of the light source. Different shapes and sizes of products and different positions of light sources or different relative positions between the sensor and the light source will cause light scattering and interference, resulting in a deviation between the brightness detected by the ambient light sensor and the actual brightness of the light source, thereby affecting the accuracy of light source detection.

[0047] The present application provides the above-mentioned solution, by adding an optical fiber and a condenser to the light source detection device, and converging the light emitted by the light source to be measured through the condenser and transmitting it to the light sensor through the optical fiber. Compared with the method of directly placing the light sensor in the environment where the light source to be measured is located, it can effectively reduce light refraction and interference, and effectively reduce the deviation between the brightness detected by the light sensor and the actual luminous brightness of the light source to be measured, thereby ensuring that the relationship between the actual brightness detected by the light sensor and the standard brightness can accurately determine whether the light source to be measured is qualified, thereby effectively improving the accuracy of light source detection.

[0048] The present application proposes a light source detection device. In this embodiment, the light source detection device is used to detect LED lights installed on electronic devices. In other embodiments, the light source detection device can also detect other light sources besides LED lights, such as tungsten filament lamps.

[0049] In this embodiment, refer to Figure 1 and Figure 2 The light source detection device includes a control device 100, an optical fiber 200, a light sensor 300 and a condenser 400. The condenser 400 is used to converge the light of the light source 600 to be measured and make it incident on the optical fiber 200, and the optical fiber 200 is used to transmit the incident light to the light sensor 300.

[0050] In this embodiment, the condenser 400 is a convex lens, the incident end of the optical fiber 200 is arranged at the focus of one side of the convex lens, and the light source 600 to be measured can be placed on the other side of the convex lens, and the object distance is greater than the focal length of the convex lens. In other embodiments, the condenser 400 can also be other optical devices with a focusing function.

[0051] In this embodiment, the emission end of the optical fiber 200 is arranged toward the photosensitive area on the optical sensor 300 .

The receiving cavity is used to receive the light source 600 to be tested and the electronic device on which it is located. During the test process, the receiving cavity is isolated from the outside to prevent the external ambient light from affecting the test result of the light source 600 to be tested.

[0053] A light source detection device proposed in this embodiment adds an optical fiber and a condenser on the basis of setting a light sensor. The light emitted by the light source 600 to be tested is converged by the condenser and transmitted to the light sensor through the optical fiber. Compared with the method of directly placing the light sensor in the environment where the light source 600 to be tested is located, it can effectively reduce light refraction and interference, and effectively reduce the deviation between the brightness detected by the light sensor and the actual luminous brightness of the light source 600 to be tested, and ensure that the relationship between the actual brightness detected by the light sensor and the standard brightness can accurately determine whether the light source 600 to be tested is qualified, thereby effectively improving the accuracy of light source detection.

[0058] The light source detection device provided by the present application adopts the light source detection method in the following embodiment, which can solve the technical problem of how to improve the accuracy of light source detection. Compared with the prior art, the beneficial effects of the light source detection device provided by the present application are the same as the beneficial effects of the light source detection method provided in the following embodiment, and other technical features in the light source detection device are the same as the features disclosed in the following embodiment method, which will not be repeated here.

[0059] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a light source detection device, etc. The following takes the light source detection device as an example to illustrate this embodiment and the following embodiments.

[0060] Based on this, the present application embodiment provides a light source detection method, referring to Figure 3 , Figure 3 This is a flow chart of the first embodiment of the light source detection method of the present application.

[0061] In this embodiment, the light source detection method includes steps S10 to S20:

[0062] Step S10, obtaining the actual brightness detected by the light sensor;

[0063] When the light source to be tested is located at the target test position, the light source to be tested can be controlled to emit light according to the preset brightness control parameters. The light emission control of the light source to be tested can be controlled by the light source detection device by sending a signal to the electronic device where the light source to be tested is located, or by the light source detection device directly connecting to the light source to be tested and sending a control signal for control.

[0064] When the light source to be tested is located at the target test position and is in a light-emitting state, the data detected by the light sensor can be obtained to obtain the actual brightness here. The actual brightness detected by the light sensor can be considered as the current light-emitting brightness of the light source to be tested.

[0065] In this embodiment, the light source to be tested is an LED lamp. In other embodiments, the light source to be tested may also be other types of light sources, such as a tungsten filament lamp.

[0066] Step S20, determining whether the light source to be tested is qualified according to the relationship between the actual brightness and the standard brightness.

[0067] The standard brightness is a preset target brightness that needs to be achieved when the light source to be tested emits light. It can be a preset fixed parameter, or it can be determined by obtaining the light source type of the light source to be tested, the installation position on the electronic device, and the prompt function.

[0068] Determine whether the light source to be tested is qualified based on the size relationship or quantitative relationship (difference or ratio, etc.) between the actual brightness and the standard brightness.

[0069] In one implementation, when the deviation value between the actual brightness and the standard brightness is less than or equal to the first preset deviation, the light source to be tested is determined to be qualified; when the deviation value between the actual brightness and the standard brightness is greater than the first preset deviation, the light source to be tested is determined to be unqualified. The deviation value here is the absolute value of the difference between the actual brightness and the standard brightness. Based on this, it is ensured that the actual luminous brightness of the qualified light source to be tested can accurately match the standard brightness.

[0070] In another implementation, when the actual brightness is greater than or equal to the standard brightness, the light source to be tested is determined to be qualified; when the actual brightness is less than the standard brightness, the light source to be tested is determined to be unqualified. Based on this, it can be ensured that the actual luminous brightness of the qualified light source to be tested will not be too dim and can reach above the standard brightness.

[0071] This embodiment provides a light source detection method based on the above light source detection device, and determines whether the light source to be tested is qualified by the relationship between the actual brightness detected by the above light source detection device and the standard brightness, thereby effectively improving the accuracy of the test of the light source to be tested.

[0072] Based on any of the above embodiments, in the second embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 4 , step S20 further includes:

[0073] Step S21, determining whether a deviation value between the actual brightness and the standard brightness is less than or equal to a first preset deviation;

[0074] When the deviation between the actual brightness and the standard brightness is less than or equal to the first preset deviation, step S22 is performed; when the deviation between the actual brightness and the standard brightness is greater than the first preset deviation, steps S23 and S24 are performed;

[0075] Step S22, determining whether the light source to be tested is qualified;

[0076] Step S23, adjusting the brightness control parameters of the light source to be tested so that the brightness of the light source to be tested changes toward the standard brightness;

[0077] When the actual brightness is greater than the standard brightness, the brightness control parameter is adjusted to reduce the brightness of the light source to be measured; when the actual brightness is less than the standard brightness, the brightness control parameter is adjusted to increase the brightness of the light source to be measured.

[0078] When adjusting the brightness control parameter, the adjustment parameter may be a preset fixed parameter, or a parameter determined according to an actual test state. For example, the adjustment parameter may be determined according to a deviation value between the actual brightness and the standard brightness.

[0079] In this embodiment, the light source to be tested is an LED lamp, and the brightness control parameter includes the duty cycle of the pulse modulation signal of the LED lamp. When the actual brightness is greater than the standard brightness, the duty cycle is reduced; when the actual brightness is less than the standard brightness, the duty cycle is increased.

[0080] Step S24, determining whether the number of times the brightness control parameter of the light source to be tested is adjusted is greater than a preset number;

[0081] When the adjustment times of the brightness control parameter of the light source to be measured is greater than the preset times, step S25 is executed; when the adjustment times of the brightness control parameter of the light source to be measured is less than or equal to the preset times, the process returns to step S10.

[0082] The preset number of times may be a preset fixed number of times, or may be determined according to the type of the light source to be measured and the installation position of the light source to be measured on the target device where the light source is located.

[0083] Step S25, determining that the light source to be tested is unqualified.

[0084] In this embodiment, when the actual brightness of the light source to be tested deviates greatly from the standard brightness, the light source is not directly judged as unqualified. Instead, the brightness of the light source is adjusted by adjusting the brightness control parameters to see whether the actual brightness can reach the standard brightness by adjusting the control parameters within a certain adjustment number range. If it can, it is judged as qualified, and if not, it is judged as unqualified. Based on this, the influence of individual differences in process, materials, etc. on the test results is effectively avoided, which is conducive to further improving the accuracy of light source testing.

[0085] In other embodiments, the light source to be tested includes a tungsten filament lamp, etc., and the brightness control parameter may include voltage and / or resistance, etc.

[0086] In a feasible implementation, before the step of adjusting the brightness control parameters of the light source to be measured so that the brightness of the light source to be measured changes toward the standard brightness, it also includes: when the deviation value is greater than the first preset deviation, determining a brightness adjustment parameter according to the standard brightness, the brightness change value of the light quantity to be measured corresponding to the brightness adjustment parameter is positively correlated with the standard brightness; adjusting the brightness control parameters of the light source to be measured according to the brightness adjustment parameter so that the brightness of the light source to be measured changes toward the standard brightness.

[0087] The brightness adjustment parameter is the adjustment amplitude when increasing or decreasing the brightness control parameter.

[0088] In this embodiment, the greater the standard brightness, the greater the brightness change value corresponding to the brightness adjustment parameter; and the smaller the standard brightness, the smaller the brightness change value corresponding to the brightness adjustment parameter.

[0089] The brightness adjustment parameter is determined according to the interval in which the standard brightness is located, or the brightness adjustment parameter is calculated by substituting the standard brightness into a formula.

[0090] The brightness adjustment parameter may include the adjustment value of the duty cycle corresponding to the above-mentioned LED light. For example, when the standard brightness is in the first brightness range, the brightness control parameter of the light source to be tested is adjusted with the first brightness adjustment parameter; when the standard brightness is in the second brightness range, the brightness control parameter of the light source to be tested is adjusted with the second brightness adjustment parameter, and the brightness in the first brightness range is greater than the brightness in the second brightness range, then the brightness change value corresponding to the first brightness adjustment parameter is greater than the brightness change value corresponding to the second brightness adjustment parameter.

[0091] In this embodiment, the above method is helpful to adapt to the actual lighting requirements of the light source to be tested for brightness calibration, ensuring that originally qualified products will not fail the test results due to excessive brightness adjustment. Based on this, it is helpful to further improve the accuracy of light source testing.

[0092] Based on any of the above embodiments, in this embodiment, after the step of determining whether the light source to be tested is qualified according to the relationship between the actual brightness and the standard brightness, it also includes: when the light source to be tested is qualified, controlling the target device where the light source to be tested is located to save the current brightness control parameters of the light source to be tested to form target control parameters, so that the target device controls the light source to be tested to achieve the standard brightness when it is lit according to the target control parameters.

[0093] The step of controlling the target device where the light source to be tested is located to save the current brightness control parameters of the light source to be tested to form target control parameters includes: sending qualified information corresponding to the light source to be tested to the target device, so that after the target device receives the qualified information, it saves the current brightness control parameters of the light source to be tested to a preset area to form target control parameters, and when the target device needs to light up the light source to be tested subsequently, it can control the light source to be tested to emit light according to the target control parameters, and the brightness of the light source to be tested can reach the standard brightness.

[0094] In this embodiment, the above method can ensure that the brightness of the light source to be tested after test and calibration can accurately reach the standard brightness when emitting light, and accurately meet the product use requirements of the target device.

[0095] Based on any of the above embodiments, in this embodiment, after the step of obtaining the actual brightness detected by the light sensor, it also includes: when the deviation value between the actual brightness and the standard brightness is greater than a second preset deviation, determining that the type of the light source to be tested is inconsistent with the preset light source type corresponding to the standard brightness; when the deviation value between the actual brightness and the standard brightness is less than or equal to the second preset deviation, executing the step of determining whether the light source to be tested is qualified according to the relationship between the actual brightness and the standard brightness.

[0096] The second preset deviation is greater than the first preset deviation.

[0097] For example, when the preset light source type is LED light, but the actual light source to be tested is tungsten filament lamp, the deviation between the brightness actually detected by the light sensor and the standard brightness will be abnormally large. At this time, it can be considered that the current light source to be tested is not the light source required for testing.

[0098] In this embodiment, through the above method, it is possible to preliminarily identify whether the type of the light source to be tested is the type of light source that needs to be tested, thereby reducing the abnormality of the detection results caused by the inconsistency between the type of the light source to be tested and the preset light source type corresponding to the standard brightness, which is conducive to further improving the accuracy of the light source test.
