Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. Based on the embodiments of the present application, every other embodiment obtained by a person skilled in the art without making any inventive effort falls within the scope of protection of the present application.
The mounting position of the gear illumination controller is determined at the beginning of the whole vehicle design, and the mounting space of the gear illumination controller is usually very narrow, so that a complex control circuit cannot be put down. Meanwhile, the light path from the light-emitting control circuit board to the final gear character is complex, the light emitted by the LEDs possibly needs to illuminate the gear character through a light channel with a large inclination angle and a light guide material, so that the brightness and the color of the LEDs used on the same key board are inconsistent, the dimming difficulty is increased, and a gear backlight product which meets the severe backlight standard of an automobile manufacturer and can meet the requirement of mass production consistency is difficult to design in a specified time.
Referring to fig. 1, fig. 1 is a flowchart of a method for determining parameters of an LED in a gear illumination controller according to an embodiment of the present application. As shown in fig. 1, a method for determining parameters of an LED in a gear illumination controller according to an embodiment of the present application includes:
s101, aiming at each LED installed in the gear illumination controller, acquiring various test display parameters and factory display parameters of the LED.
In this step, each LED installed in the gear illumination controller is located below a gear character for illuminating the gear character. Here, one LED may be provided under one shift character, or one LED may be provided under a plurality of shift characters. The gear illumination controller is a debugging component which is not installed on the whole vehicle, and also can be a testing component which is required to be detected after being installed on the whole vehicle. Wherein different ones of the LEDs may be selected for mounting in the gear illumination controller.
Here, each LED installed in the range lighting controller may be an LED preliminarily selected based on display requirements of the vehicle manufacturer for the range lighting controller, where the display requirements include a light emission luminance requirement and a light emission color requirement. Each LED selected to be mounted in the range lighting controller may also be selected in consideration of the structure of the range lighting controller, which determines the mounting position of the LED and the light emission condition of the LED through the character cover of the range lighting controller.
Optionally, the test display parameter includes a first test luminance value, a second test luminance value, and a test color coordinate; the first test brightness value is the brightness value of the LED when the minimum rated current of the LED is connected; the second test brightness value is the brightness value of the LED when the LED is connected with the maximum rated current of the LED; the test color coordinates are coordinates of the color of the LED when the LED is connected with the minimum rated current or the maximum rated current of the LED.
Here, the minimum rated voltage of an LED is the current MIN value recorded by DATASHEET of the LED, and the maximum rated current of an LED is the current MAX value recorded by DATASHEET of the LED. The first test luminance value, the second test luminance value, and the luminance value corresponding when any one of the MIN current and the MAX current is turned on of the LEDs may be tested using the luminance meter. The test color coordinates of the LED may be obtained using a spectrometer test, and the test color coordinates may determine a color point on the CIE1931 chromaticity diagram that accurately represents the emission color.
Wherein, the brightness and the current are in positive correlation, the smaller the current is, the darker the current is, and the larger the current is, the brighter the current is. Under the same test conditions, the on-current of the LED is changed (not exceeding or being lower than the current range recorded in DATASHEET), the change of the test color coordinates is small, and the test color coordinates can be considered to be unchanged when the current is changed within a certain range.
Optionally, the factory display parameters include a factory luminous intensity reference value, a factory luminous intensity range, a factory color coordinate reference value and a factory color coordinate range; the reference value of the luminous intensity of the outgoing light is the luminous intensity value when the LED is connected with outgoing test current; the factory luminous intensity range is a luminous intensity range when the factory test current is recorded in a factory data table of the LED; the reference value of the factory color coordinate is the coordinate of the color when the LED is connected with the factory test current; and the factory color coordinate range is a color coordinate range of the color recorded in a factory data table of the LED when the factory test current is connected.
Here, the factory display parameters may include parameters recorded in DATASHEET and precision test parameters provided from the manufacturer, which are display parameters provided from the LED manufacturer with respect to the LEDs. The reference value of the factory luminous intensity is the same as the current value of the factory test current used in the factory luminous intensity range.
S102, determining whether abnormal display parameters which do not meet preset display requirements exist in the plurality of test display parameters of the LED or not based on the plurality of test display parameters and preset reference display parameters of each test display parameter.
Optionally, the reference display parameter includes a reference backlight brightness range, a reference assembly brightness range, and a reference color coordinate range; the backlight brightness is the display brightness of gear characters which are not in gear on the gear illumination controller, the assembly brightness is the display brightness of the gear characters which are in gear on the gear illumination controller, and the reference color coordinate range indicates the color range which can be displayed by the gear characters of the gear illumination controller.
In this step, the reference display parameter may be a display parameter autonomously determined by the automobile manufacturer, or may be a standard parameter set in the automobile industry.
For example, a certain automobile has a gear illumination controller with P, R, N, D/S, a few gears with +/-V, and all gears are lightened after power is applied. The automobile manufacturer has a unified standard for displaying all gear characters, and the brightness of the current gear character is required to be obviously higher than that of the other gear characters, the brightness of the gear assembly is required to be n times of that of the backlight of the other gears, for example, the brightness of the reference assembly is required to be 10A cd/m 2, the brightness of the other reference backlight is required to be A cd/m 2, in order to ensure the consistency of visual brightness, the automobile manufacturer also specifies the brightness tolerance, and the standard tolerance is usually specified to be +/-25%, so that the reference backlight brightness range and the reference assembly brightness range are determined. In addition to the requirements for brightness uniformity and color uniformity of the gear illumination controller, automobile manufacturers generally require that all gear characters look uniform, so that a color coordinate area of a CIE1931 chromaticity diagram or a wavelength range of monochromatic light is defined as a color qualification area. For example, the reference color coordinate range is required to be a hexagonal area surrounded by color coordinates (x 0, y 0), (x 1, y 1), (x 2, y 2), (x 3, y 3), (x 4, y 4), (x 5, y 5).
Optionally, the determining, based on the multiple test display parameters and the preset target display parameter of each test display parameter, whether there is an abnormal display parameter that does not meet the preset display requirement in the multiple test display parameters of the LED; determining whether a first test luminance value of the LED is greater than a backlight luminance maximum value in the reference backlight luminance range; if yes, determining that the first test brightness value of the LED is an abnormal display parameter which does not meet the preset display requirement; determining whether a second test luminance value of the LED is less than a total luminance minimum in the reference total luminance range; if yes, determining that a second test brightness value of the LED is an abnormal display parameter which does not meet the preset display requirement; determining whether a color point corresponding to the test color coordinate of the LED is positioned in a color area formed by the reference color coordinate range, and whether the overlapping area between a color coordinate BIN area corresponding to the test color coordinate of the LED and the color area formed by the reference color coordinate range reaches a preset overlapping threshold value; and when the color point is not in the color area and/or does not reach the preset coincidence threshold value, determining that the test color coordinates of the LED are abnormal display parameters which do not meet the preset display requirements.
In this step, the first test luminance value of each LED is the lowest luminance that the LED can reach in the rated operating current range, and when the lowest luminance of the LED is still brighter than the maximum luminance value in the reference backlight luminance range, it is indicated that the luminance of the LED is too high, and does not meet the backlight display luminance requirement. The second test brightness value of each LED is the highest brightness which can be achieved by the LED in the rated working current range, and when the highest brightness of the LED is still brighter than the minimum brightness value in the brightness range of the reference assembly, the LED brightness is too low, and the requirement of backlight display brightness is not met.
Here, for the LEDs whose display luminance satisfies the requirement, the control currents corresponding to the respective LED test luminance values in the reference backlight luminance range and the reference assembly luminance range are determined based on the relationship between the currents and the positive correlations of the luminance.
Judging whether the color of the LED meets the requirement or not, and simultaneously judging whether the color point corresponding to the test color coordinate on the chromaticity diagram is positioned in the color area formed by the reference color coordinate range on the chromaticity diagram or not, and judging whether the overlapping area between the color coordinate BIN area corresponding to the test color coordinate of the LED and the color area formed by the reference color coordinate range reaches a preset overlapping threshold value, wherein the preset overlapping threshold value can be set by an automobile manufacturer.
Here, the BIN area for the color coordinates of the test coordinates can be determined from DATASHEET of the LEDs, because the manufacturer of the current LED performs a luminous intensity and color coordinate division for each LED, which is generally called BIN area.
For example, referring to fig. 2, fig. 2 is a schematic diagram illustrating a relationship between a test color coordinate and a reference color coordinate range. As shown in fig. 2, P is the test color coordinates of the LED used in the P-stage in the gear controller, N is the test color coordinates of the LED used in the N-stage in the gear controller, a is the color region constituted by the reference color coordinate range, B is the color coordinate BIN region corresponding to the test color coordinates of the LED used in the P-stage, and C is the color coordinate BIN region corresponding to the test color coordinates of the LED used in the N-stage. If the preset coincidence threshold is 80%, that is, the color coordinate BIN area is required to be 80% in the a, then according to fig. 2, it can be determined that the test color coordinates of the LEDs used in the P-stage are abnormal display parameters, and the test color coordinates of the LEDs used in the N-stage are qualified display parameters, so that it can be determined that the LEDs used in the P-stage are unsuitable and need to be replaced. It should be noted that, the color coordinate judgment mode of the LEDs used in other gear is the same as the judgment modes of the P-gear and the N-gear, and will not be described here again.
And S103, if so, determining the display parameter offset of each abnormal display parameter which does not meet the preset display requirement according to the offset determination mode corresponding to the abnormal display parameter.
The display parameter offset is generated by a gear character cover of the gear lighting controller, the LEDs are welded on a control circuit board of the gear lighting controller, and the display parameter is tested to test the measured parameter after the gear character cover is buckled on the control circuit board. Because the light guide sheet and the black processing part of the light guide sheet on the character cover can influence the light emitted by the LED, the test display parameters are different from the factory display parameters of the LED, and offset is generated.
Optionally, the determining, according to the offset determining manner corresponding to the abnormal display parameter, the display data offset of the abnormal display parameter includes: when the first test brightness value is an abnormal display parameter, determining the offset of the first test brightness value of the LED based on the factory luminous intensity value of the LED and the first debugging brightness value of the LED; when the second test brightness value is an abnormal display parameter, determining the offset of the second test brightness value of the LED based on the factory luminous intensity value of the LED and the second debugging brightness value of the LED; and when the test color coordinates are abnormal display parameters, determining the offset of the test color coordinates of the LED based on the factory color coordinates and the test color coordinates of the LED and the factory color coordinates and the test color coordinates of other LEDs which belong to the same display type with the LED in the gear illumination controller.
In this step, the display parameter offset is mainly composed of a luminance offset and a color offset, and includes: an offset of the first test luminance value, an offset of the second test luminance value, and an offset of the test color coordinates.
Here, the display types include direct display and indirect display. Direct display means that the LED used for the gear character is directly under the character, and indirect display means that the LED used is not directly under the character. In which direct gear characters and indirect gear characters are commonly present in an automotive gear lighting control.
Optionally, when the first test luminance value is an abnormal display parameter, determining, based on the factory emission intensity value of the LED and the first debug luminance value of the LED, an offset of the first test luminance value of the LED includes: determining a detected light-emitting brightness value of the LED when the LED is connected with a factory test current based on a first test brightness value and a minimum rated current of the LED; determining a factory emission brightness value of the LED based on the factory emission intensity value of the LED; and determining the offset of the first test brightness value of the LED based on the factory brightness value of the LED and the detection brightness value of the LED.
It should be noted that, the method for determining the offset of the second test luminance value is the same as the method for determining the offset of the first test luminance value, and will not be described herein.
Here, one of the reasons why the detected luminance value is different from the factory luminance value is that the effective light emission angle affects the luminance, and the reasons for affecting the angle are mainly the black paint length of the light guide sheet and the position of the LED. For example, refer to fig. 3 and 4. Fig. 3 is a radar chart showing the relationship between the illumination angle and the luminous intensity of the LED, and fig. 4 is a schematic view of the LED in the gear illumination controller. 1-character cover cap; 2-a light guide sheet; a. b and c are black-coating treatment parts of the light guide sheet; 3-left side light channel structure; 4-a circuit board; 5 right side light channel structure; LEDs used in 6-N grades; 7-direct LED luminescence; the 8-LED light-emitting angle is 40 degrees; the 9-LED light-emitting angle is 50 degrees; the 10-LED light-emitting angle is 60 degrees; the lighting angle of the 11-LED is 70 degrees; 12-LED moved back position.
As shown in fig. 3, the emission intensity value at the time of direct irradiation is 1 (for example, the nominal emission intensity of the LED is 100mcd, and the emission intensity at this time is 1×100 mcd). The angular illumination (non-direct) luminous intensity value is correspondingly reduced. For example, the luminous intensity is 0.9x100=90 mcd at 20 °). As shown in fig. 4, the N-level character is used to illustrate why the luminance values of the indirect characters are likely to differ more.
First, the effect of the effective light emission angle on the luminance, if the effective light emission area is 50 ° to 60 °, then the effective luminance (0.65+0.5)/2×100=57.5 mcd; if the effective light emitting area is 40 ° to 70 °, then the effective luminance is (0.75+0.35)/2×100=55 mcd.
The reasons for the influence of the angle are mainly the black paint length of the light guide sheet and the position of the LED, if the non-shielding area is 60 ° to 70 °, the effective brightness (0.5+0.35)/2×100=42.5 mcd, and if the non-shielding area is 40 ° to 70 °, the effective brightness (0.75+0.35)/2×100=55 mcd, so that the brightness when the same circuit board corresponds to two covers differs by about 30%.
Effect of the relative position of the LEDs if we move the LEDs to the dashed line position, the effective light emitting area changes from 60 ° to 70 ° (42.5 mcd) to 40 ° to 50 ° (70 mcd), and the corresponding two different positions differ in brightness by about 60%.
The relative angle of the LED, if we lift the LED 5 °, the effective light emitting area becomes 45 ° to 65 ° (55 mcd) from 40 ° to 60 ° (62.5 mcd), and the two corresponding different positions differ in brightness by about 14%.
Optionally, when the test color coordinate is an abnormal display parameter, determining the offset of the test color coordinate of the LED based on the factory color coordinate value and the test color coordinate value of the LED, and the factory color coordinate value and the test color coordinate value of other LEDs in the gear illumination controller, which belong to the same display type with the LED, includes: determining a first color coordinate offset of the LED based on the test color coordinate value and the factory color coordinate value of the LED; determining a second color coordinate offset of the LED based on the test color coordinate value and the factory color coordinate value of the LED for each other LED belonging to the same display type as the LED in the gear illumination controller; determining an average color coordinate offset based on the first color coordinate offset of the LED and the second color coordinate offsets of other LEDs of the same display type; and determining the determined average color coordinate offset as the color coordinate offset of the LED.
Here, when determining the color coordinate shift amount of an LED, it is necessary to determine the display type of the LED first. When the test color coordinates of the LED are abnormal display parameters and the LED is direct display, the color coordinate offset of each direct display LED in the gear illumination controller can be determined according to the factory color coordinate values and the test color coordinate values, and the average color coordinate offset, namely the color coordinate offset of each direct display LED, is calculated based on the color coordinate offsets of all the direct display LEDs. The method for calculating the color coordinate offset of the non-direct display LED is the same as the method for calculating the color coordinate offset of the direct display LED, and will not be described here again.
For example, to more intuitively determine the amount and extent of offset of the color coordinates, it may be determined by a specific location in the chromaticity diagram. Referring to fig. 5, fig. 5 is a schematic diagram of LED color coordinate shift. A is a color area formed by a reference color coordinate range, D is a factory color coordinate range corresponding to an LED used by each gear character, D is a factory color coordinate of the LED used by the gear character, E is a test color coordinate BIN area corresponding to the LED used by each gear character, and E is a test color coordinate of the LED used by the gear character. From the illustration of fig. 5, it is visually recognized whether the color is acceptable or not, and the offset of the color coordinates is calculated.
S104, the display parameter offset of the LED and the factory display parameter of the LED are sent to a client, so that debugging personnel of the client can determine the factory display parameter of the target LED meeting the preset display requirement based on the display parameter offset and the factory display parameter.
In the step, after determining the LED which does not meet the display requirement and the display item which does not meet the display requirement of the LED, sending the factory display parameters of the display item which does not meet the display requirement of the LED and the display parameter offset corresponding to the display item to a debugging person at the client, wherein the debugging person can determine the factory display parameters of the target LED which meets the preset display requirement.
Here, the factory display parameters corresponding to the target LEDs with the test display parameters meeting the reference display parameter requirements can also be directly calculated based on the display parameter offset and the reference display parameters, and the determined factory display parameters are sent to the debugging personnel, so that the debugging personnel can directly replace the failed LEDs.

In this way, the application compares the test display parameters obtained after passing through the gear illumination controller with the factory display parameters to determine the influence of the gear illumination controller on the brightness and the color of the LED, and respectively determines the brightness offset and the color offset, thereby enabling a debugger to rapidly determine the LED meeting the display requirements, and generally, the standard dimming can be completed by two-round test, and further the debugging efficiency can be improved.
