[0049] This specification may use the phrase "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", each of which may refer to one or more of the same or different embodiments according to the present application.

[0050] A testing method for an LED lamp according to an embodiment of the present application, which can be applied to test the LED lamp used in an electronic device to facilitate the electronic device to determine the installation environment of the LED lamp, especially to facilitate the determination of the auxiliary device of the LED lamp in the electronic device, thereby improving the production efficiency of the electronic device. For example, in the design stage of an electronic device, an LED lamp group needs to be used, and the electronic device itself needs to install corresponding auxiliary components to cooperate with the LED lamp group to work. This includes resistors associated with the LED lamp group, but it is necessary to first determine what parameters of the resistors to install. In this embodiment, an independent testing environment can be used to test the LED lamp group. According to the situation where the LED lamp group works normally, such as the light intensity, etc., to determine the parameters of other components that cooperate with the LED lamp group during operation, such as the parameters of the above-mentioned resistors, so as to facilitate the installation of suitable resistors in the electronic device. Since this testing environment can test multiple LED lamps separately, the testing efficiency can be effectively improved.

[0051] The following will describe this method in detail with reference to the accompanying drawings, as Figure 1 shown, the method includes the following steps:

[0052] S100, determine a first LED lamp with a first luminous intensity and a second LED lamp with a second luminous intensity from the LED lamp group, where the first luminous intensity is less than the second luminous intensity.

[0053] Exemplarily, the LED lamp group includes a plurality of LED lamps, but the parameters of all the LED lamps are not completely the same, for example, the luminous intensities of the plurality of LED lamps are different. A first LED lamp and a second LED lamp having different parameters are selected from the LED lamp group.

[0054] In one embodiment, the first LED lamp may be an LED lamp selected from the LED lamp group and having the smallest luminous intensity, and the second LED lamp may be an LED lamp selected from the LED lamp group and having the largest luminous intensity. That is, the first LED lamp has a first luminous intensity that is the smallest value among the luminous intensities of all LED lamps, and the second LED lamp has a second luminous intensity that is the largest value among the luminous intensities of all LED lamps.

[0055] After the first LED lamp and the second LED lamp are determined, they can be placed in a test environment and tested using a test system.

[0056] S200, when both the first LED lamp and the second LED lamp meet the target luminous intensity range, determine a first test resistance range corresponding to the first LED lamp and a second test resistance range corresponding to the second LED lamp using a test device in a constructed test environment.

[0057] For example, the test environment may be an environment for testing various parameters of an LED lamp and various parameters of ancillary equipment of the LED lamp, and the test environment corresponds to a test system. Figure 6 The test system includes at least one test device, such as a test device including a variable resistor, an illuminance meter, a light shield, a controller, and a placement structure for placing an LED lamp.

[0058] In this embodiment, in a test environment, a plurality of test devices with different functions are used to continue testing the first LED lamp and the second LED lamp. Under the condition that both the first LED lamp and the second LED lamp meet the target luminous intensity range, a first test resistance range corresponding to the first LED lamp can be determined, that is, when the first LED lamp is adjusted within the first test resistance range, the luminous intensity of the first LED lamp meets the target luminous intensity range. The first test resistance range can be a numerical range. Similarly, a second test resistance range corresponding to the second LED lamp can be determined, that is, when the second LED lamp is adjusted within the second test resistance range, the luminous intensity of the second LED lamp meets the target luminous intensity range, and the second test resistance range can be another numerical range.

[0059] In one embodiment, under the same conditions, when the brightness value of the first LED lamp is the smallest in the LED lamp group and the brightness value of the second LED lamp is the largest in the LED lamp group, the average value in the first test resistance range is less than the average value in the second test resistance range.

[0060] S300. Based on the first test resistance range and the second test resistance range, determine the target resistance range corresponding to the LED lamp group in the working state.

[0061] Exemplarily, the average value of the first test resistance range can be the smallest among the average values of the test resistance ranges corresponding to all the LED lamps in the LED lamp group; the average value of the second test resistance range can be the largest among the average values of the test resistance ranges corresponding to all the LED lamps in the LED lamp group.

[0062] Based on the first test resistance range and the second test resistance range, the target resistance range applicable to all the LED lamps in the LED lamp group can be determined. This target resistance range can be applied in an electronic device. The current-limiting resistor set based on this target resistance range can enable all the LED lamps in the LED lamp group to emit light normally, so that multiple LED lamps can meet the production requirements of the electronic device.

[0063] This test method can, for multiple LED lamps, determine the current-limiting resistor adapted to them according to the actual parameters of the LED lamps, so that after using this current-limiting resistor in the production process of the electronic device, it can be adapted to multiple LED lamps with similar parameters to be installed, thereby making the electronic device more adaptable and reducing the production cost.

[0064] In one embodiment of the present application, after determining the target resistance range, as Figure 2 shown, the method further includes the following steps:

[0065] S400. When both the first LED lamp and the second LED lamp meet the target luminous intensity range, respectively determine the first light guide test parameter corresponding to the first LED lamp in the test environment and the second light guide test parameter corresponding to the second LED lamp in the test environment.

[0066] Exemplarily, when testing the first LED lamp and the second LED lamp, an illuminometer module is needed to detect their luminous intensity. For example, the light emitted by the LED and guided out by the light guide column in the light guide column module is tested through the photosensitive probe of the illuminometer, so that the first light guide test parameter corresponding to the first LED lamp in the test environment and the second light guide test parameter corresponding to the second LED lamp in the test environment can be obtained.

[0067] In one embodiment, with the current-limiting resistor unchanged, a corresponding voltage can be applied to the first LED lamp, and then the first light guide test parameter corresponding to the first LED lamp can be determined. When the first LED lamp operates under the first light guide test parameter, it can emit light normally, and the light-emitting intensity meets the preset requirements. The first light guide test parameter can be the light guide parameter of the light guide column corresponding to the first LED lamp.

[0068] Similarly, with the current-limiting resistor unchanged, a corresponding voltage can be applied to the second LED lamp, and then the second light guide test parameter corresponding to the second LED lamp can be determined. When the second LED lamp operates under the second light guide test parameter, it can emit light normally, and the light-emitting intensity meets the preset requirements.

[0069] S500, based on the first light guide test parameter and the second light guide test parameter, determine the target light guide parameter corresponding to the LED lamp group in the working state.

[0070] Exemplarily, the luminous performances corresponding to the first LED lamp and the second LED lamp are the strongest and the weakest in the LED lamp group respectively. Thus, the light guide effects corresponding to the first light guide parameter and the second light guide parameter can be the weakest and the strongest respectively. Furthermore, based on the first light guide test parameter and the second light guide test parameter, the determined target light guide parameter can enable all the LED lamps in the LED lamp group to emit light normally, ensuring that the light-emitting intensity meets the requirements. The electronic device can determine light guide elements such as light guide columns according to the target light guide parameter, so that the installed light guide elements can be adapted to more LED lamps. The high adaptability can enable the electronic device to reduce production costs.

[0071] In one embodiment of the present application, the method further includes the following steps: place the first LED lamp and the second LED lamp at the test positions in the test environment for testing respectively, where the test environment is different from the usage environment of the first LED lamp and / or the second LED lamp.

[0072] Exemplarily, the test environment in this embodiment is different from the installation environment of the electronic device. Thus, a large number of LED lamp groups can be tested separately. The test environment corresponds to a test system, and the test system includes at least one test device, such as Figure 6 and Figure 7 as shown. For example, the test device includes a variable resistor, an illuminometer, a light-shielding cover, a controller, and an installation structure for placing the LED lamp, etc.

[0073] In a specific embodiment, the controller can select the power supply for the test system, such as selecting the USB interface as the power supply. The controller can appear in the form of a power supply and a resistance control box, which has a display screen capable of displaying the resistance value of the sliding rheostat during the test. The controller can include a single-chip microcomputer, a digital-to-analog conversion module, and a crystal oscillator for providing the clock frequency. The controller is respectively connected to the power supply and the placement structure, delivering power to the placement structure, and the analog-to-digital conversion module can adjust the variable resistor (current-limiting resistor). The placement structure has test positions (which can be jigs) for placing the LED lights, capable of holding the first LED light or the second LED light; a light guide column container for accommodating the light guide column is also provided on the placement structure, which can guide the light emitted by the LED light to the illuminance meter module, and a light-shielding cover is also provided outside the placement structure, which can cover the placement structure to prevent light leakage. During the test, the first LED light and the second LED light can be respectively placed in the jigs, the light guide column can be placed in the container and filled with black rubber clay, the probe of the illuminance meter can be placed at the corresponding position of the jig, after adjusting the relative positions of the three, the LED is lit, and the light-shielding cover is placed outside the placement structure.

[0074] In an embodiment of the present application, the test device includes a variable resistor. When both the first LED light and the second LED light meet the target luminous intensity range, the first test resistance range corresponding to the first LED light and the second test resistance range corresponding to the second LED light are determined by using the test device in the constructed test environment, as Figure 3 shown, including:

[0075] S210, applying a corresponding test voltage to the first LED light installed at the test position;

[0076] S220, adjusting the variable resistor, and determining the first test resistance range when the target luminous intensity range is met;

[0077] S230, applying a corresponding test voltage to the second LED light installed at the test position;

[0078] S240, adjusting the variable resistor, and determining the second test resistance range when the target luminous intensity range is met.

[0079] Exemplarily, the controller can select a power source to supply power to the first LED lamp installed at the test position. For example, USB is selected as the power supply to apply a test voltage to the first LED lamp. The controller can be equipped with a display screen that can display the test voltage of the first LED lamp. The controller has a digital-to-analog conversion module, which can adjust a variable resistor (current-limiting resistor) to adjust the test voltage. The illuminometer module collects the light intensity of the first LED lamp during the adjustment process. When the target luminous intensity range is satisfied, the first test resistor range corresponding to the variable resistor is determined, that is, the light intensity emitted by the first LED lamp within the first test resistor range can meet the target luminous intensity. The target luminous intensity can be set according to the physical parameters of the first LED lamp or according to the actual requirements of the usage scenario.

[0080] Similarly, the digital-to-analog conversion module can adjust a variable resistor (current-limiting resistor) to adjust the test voltage. The illuminometer module collects the light intensity of the second LED lamp during the adjustment process. When the target luminous intensity range is satisfied, the second test resistor range corresponding to the variable resistor is determined, that is, the light intensity emitted by the second LED lamp within the second test resistor range can meet the target luminous intensity.

[0081] In an embodiment of the present application, based on the first test resistor range and the second test resistor range, the target resistor range corresponding to the LED lamp group in the working state is determined, such as Figure 4 and Figure 8 shown, including:

[0082] S310, compare the first test resistor range with the second test resistor range.

[0083] Exemplarily, the values in the first test resistor range can be compared with the values in the second test resistor range, so as to determine which values in the first test resistor range overlap with the values in the second test resistor range and which are different from the values in the second test resistor range.

[0084] S320, determine the overlapping part of the first test resistor range and the second test resistor range as the target resistor range.

[0085] Exemplarily, for the values in the target resistor range corresponding to the overlapping part, the current-limiting resistor can be adjusted within this range so that the luminous intensities of the first LED lamp and the second LED lamp both meet the target luminous intensity requirements. As Figure 8 shown, R1 to R2 is the first test resistor range, R3 to R4 is the second test resistor range, and the overlapping part is Figure 8The shaded part in. After determining the target resistance range, the resistor corresponding to the target resistance range can be installed in the electronic device, and the electronic device can meet the requirements of the LED lamp whose luminous performance is between the first LED lamp and the second LED lamp. The adaptability of the electronic device is enhanced, and the production cost is reduced.

[0086] In an embodiment of the present application, based on the first test resistance range and the second test resistance range, determine the target resistance range corresponding to the LED lamp group in the working state, as Figure 5 shown, including:

[0087] S330, determine the light guide test parameters corresponding to the LED lamp group;

[0088] S340, with the light guide test parameters unchanged, determine the overlapping part of the first test resistance range and the second test resistance range as the target resistance range.

[0089] Exemplarily, when determining the target resistance range, it is necessary to first determine the light guide test parameters corresponding to the LED lamp group. For example, the light guide column corresponding to the LED lamp group can export the light emitted by the LED lamp, and determine the light guide test parameters of the light guide column. With the light guide test parameters unchanged, the above overlapping part is determined as the target resistance range, thus ensuring the accuracy of the target resistance range.

[0090] The embodiment of the present application also provides a test system for an LED lamp, as Figure 6 and Figure 9 shown, including:

[0091] A selection module configured to determine a first LED lamp with a first luminous intensity and a second LED lamp with a second luminous intensity from the LED lamp group, wherein the first luminous intensity is less than the second luminous intensity.

[0092] Exemplarily, the LED lamp group includes multiple LED lamps, but the parameters of all the LED lamps are not exactly the same. For example, the luminous intensities of the multiple LED lamps are different. The selection module selects the first LED lamp and the second LED lamp with different parameters from the LED lamp group. For example, the selection module selects the first LED lamp and the second LED lamp through the identification information of each LED lamp.

[0093] In one embodiment, the first LED lamp can be the LED lamp with the minimum luminous intensity selected from the LED lamp group, and the second LED lamp can be the LED lamp with the maximum luminous intensity selected from the LED lamp group. That is, the first LED lamp has the first luminous intensity which is the minimum value among the luminous intensities of all the LED lamps, and the second LED lamp has the second luminous intensity which is the maximum value among the luminous intensities of all the LED lamps.

[0094] After determining the first LED lamp and the second LED lamp, they can be respectively placed in a test environment and tested using a test device.

[0095] A test device, including a variable resistor, an illuminometer, and a controller. Wherein, the illuminometer is used to determine the target luminous intensity range of the first LED lamp and the second LED lamp, and the controller is used to control the variable resistor to slide and change when both the first LED lamp and the second LED lamp meet the target luminous intensity range, so as to determine the first test resistor range corresponding to the first LED lamp and the second test resistor range corresponding to the second LED lamp; the controller is further used to determine the target resistor range corresponding to the LED lamp group in the working state based on the first test resistor range and the second test resistor range.

[0096] Exemplarily, at least one test device is included in this test system. For example, the test device includes a variable resistor, an illuminometer, a light-shielding cover, a controller, and an installation structure for installing the LED lamp, etc.

[0097] In this embodiment, in the test environment, the first LED lamp and the second LED lamp are continuously tested using multiple test devices with different functions. The variable resistor is used to respectively adjust the test voltages of the first LED lamp and the second LED lamp to change their light intensities.

[0098] The illuminometer is used to monitor the light intensities of the first LED lamp and the second LED lamp. When ensuring that both the first LED lamp and the second LED lamp meet the target luminous intensity range, the controller can determine the first test resistor range corresponding to the first LED lamp, that is, when the first LED lamp is adjusted within the first test resistor range, the luminous intensity of the first LED lamp meets the target luminous intensity range. The first test resistor range can be a numerical range. Similarly, the controller can determine the second test resistor range corresponding to the second LED lamp, that is, when the second LED lamp is adjusted within the second test resistor range, the luminous intensity of the second LED lamp meets the target luminous intensity range, and the second test resistor range can be another numerical range.

[0099] In one embodiment, under the same conditions, when the brightness value of the first LED lamp is the smallest in the LED lamp group and the brightness value of the second LED lamp is the largest in the LED lamp group, the average value in the first test resistor range is less than the average value in the second test resistor range.

[0100] Exemplarily, the average value of the first test resistance range can be the smallest among the average values of the test resistance ranges corresponding to all the LED lights in the LED light group; the average value of the second test resistance range can be the largest among the average values of the test resistance ranges corresponding to all the LED lights in the LED light group.

[0101] Based on the first test resistance range and the second test resistance range, the controller can determine a target resistance range suitable for all the LED lights in the LED light group. This target resistance range can be applied to an electronic device, and the current-limiting resistor set based on this target resistance range can enable all the LED lights in the LED light group to emit light normally, so that multiple LED lights can meet the production requirements of the electronic device.

[0102] In an embodiment of the present application, the system further includes a light guide column module for conducting the emitted light of the LED light group.

[0103] The light guide column module is used to respectively determine a first light guide test parameter corresponding to the first LED light in the test environment and a second light guide test parameter corresponding to the second LED light in the test environment when both the first LED light and the second LED light meet the target light emission intensity range.

[0104] Exemplarily, when testing the first LED light and the second LED light, an illuminometer module is required to detect their light emission intensities. For example, the light emitted by the LED and guided out by the light guide column in the light guide column module is tested through the photosensitive probe of the illuminometer, so that a first light guide test parameter corresponding to the first LED light in the test environment and a second light guide test parameter corresponding to the second LED light in the test environment can be obtained.

[0105] In an embodiment, when the current-limiting resistor (which can be a variable resistor) remains unchanged, the controller can apply a corresponding voltage to the first LED light, and then determine the first light guide test parameter corresponding to the first LED light. The first LED light operates under the first light guide test parameter, can emit light normally, and the light emission intensity meets the preset requirements. This first light guide test parameter can be the light guide parameter of the light guide column corresponding to the first LED light.

[0106] Similarly, when the current-limiting resistor remains unchanged, the controller can apply a corresponding voltage to the second LED light, and then determine the second light guide test parameter corresponding to the second LED light. The second LED light operates under the second light guide test parameter, can emit light normally, and the light emission intensity meets the preset requirements.

[0107] Exemplarily, the luminous performance corresponding to the first LED lamp and the second LED lamp is the strongest and the weakest in the LED lamp group respectively. Thus, the light guiding effects corresponding to the first light guiding parameter and the second light guiding parameter can be the weakest and the strongest respectively. Furthermore, based on the first light guiding test parameter and the second light guiding test parameter, the determined target light guiding parameter can enable all the LED lamps in the LED lamp group to emit light normally and ensure that the luminous intensity meets the requirements. The electronic device can determine light guiding elements such as a light guiding column according to the target light guiding parameter, so that the installed light guiding elements can be adapted to more LED lamps. The high adaptability enables the electronic device to reduce production costs.

[0108] In an embodiment of the present application, the test device further includes an installation structure, which has a test position. The test position carries the first LED lamp and the second LED lamp, so that the first LED lamp and the second LED lamp are tested in a test environment, where the test environment is different from the usage environment of the first LED lamp and / or the second LED lamp.

[0109] Exemplarily, the test environment in this embodiment is different from the installation environment of the electronic device. Thus, a large number of LED lamp groups can be tested separately. The test environment corresponds to a test system, and the test system includes at least one test device. For example, the test device includes a variable resistor, an illuminometer, a light-shielding cover, a controller, and an installation structure for installing the LED lamp, etc.

[0110] In a specific embodiment, in combination with Figure 6 and Figure 7 , the controller can select the power supply of the test system, such as selecting a USB interface as the power supply. The controller can appear in the form of a power supply and a resistance value control box, which has a display screen and can display the resistance value of the sliding rheostat during the test. The controller can include a single-chip microcomputer, a digital-to-analog conversion module, and a crystal oscillator for providing a clock frequency. The controller is respectively connected to the power supply and the installation structure, delivers power to the installation structure, and the analog-to-digital conversion module can adjust the variable resistor (current-limiting resistor). The installation structure has a test position (which can be a fixture) for installing the LED lamp and can hold the first LED lamp or the second LED lamp; a light guiding column container for accommodating the light guiding column is also arranged on the installation structure, which can guide the light emitted by the LED lamp to the illuminometer module. A light-shielding cover is also arranged outside the installation structure, and the light-shielding cover can cover the installation structure to prevent light from leaking. During the test, the first LED lamp and the second LED lamp can be respectively placed in the fixture, the light guiding column can be placed in the container and filled with black rubber clay, the probe of the illuminometer can be placed at the corresponding position of the fixture. After adjusting the relative positions of the three, the LED is lit, and the light-shielding cover is placed outside the installation structure.

[0111] In one embodiment of the present application, the test device further includes a power supply module, and the controller is connected to the power supply module;

[0112] The power supply module is used to apply a corresponding test voltage to the first LED lamp installed at the test position, so that the controller adjusts the variable resistor, and when the target luminous intensity range is satisfied, the first test resistance range is determined;

[0113] The power supply module is also used to apply a corresponding test voltage to the second LED lamp installed at the test position, so that the controller adjusts the variable resistor, and when the target luminous intensity range is satisfied, the second test resistance range is determined.

[0114] Exemplarily, the controller can select the power supply module to supply power to the first LED lamp installed at the test position. For example, USB is selected as the power supply to apply a test voltage to the first LED lamp. The controller can have a display screen that can display the test voltage of the first LED lamp. The controller has an analog-to-digital conversion module, and the analog-to-digital conversion module can adjust the variable resistor (current-limiting resistor), thereby adjusting the test voltage. The illuminometer module collects the light intensity of the first LED lamp during the adjustment process. When the target luminous intensity range is satisfied, the first test resistance range corresponding to the variable resistor is determined, that is, the light intensity emitted by the first LED lamp within the first test resistance range can meet the target luminous intensity. The target luminous intensity can be set according to the physical parameters of the first LED lamp or according to the actual requirements of the usage scenario.

[0115] Similarly, the analog-to-digital conversion module can adjust the variable resistor (current-limiting resistor), thereby adjusting the test voltage. The illuminometer module collects the light intensity of the second LED lamp during the adjustment process. When the target luminous intensity range is satisfied, the second test resistance range corresponding to the variable resistor is determined, that is, the light intensity emitted by the second LED lamp within the second test resistance range can meet the target luminous intensity.

[0116] In one embodiment of the present application, the test device is further used for:

[0117] Compare the first test resistance range with the second test resistance range;

[0118] Determine the overlapping part of the first test resistance range and the second test resistance range as the target resistance range.

[0119] In one embodiment of the present application, the test device is further used for:

[0120] Determine the light guide test parameters corresponding to the LED lamp group;

[0121] With the light guide test parameters unchanged, the overlapping part of the first test resistance range and the second test resistance range is determined as the target resistance range.
