The invention provides the solution, and aims to realize accurate calibration of control parameters of the LED lamp so as to ensure the brightness consistency of different LED lamps.
The invention provides a parameter adjusting device which is mainly applied to calibrating brightness control parameters preset in an LED lamp.
In an embodiment of the present invention, referring to fig. 1, the parameter adjusting apparatus includes: a processor 1001, such as a CPU, a memory 1002, and a brightness detection module 1003. The memory 1002 may be a high-speed RAM memory or a non-volatile memory (e.g., a disk memory). The memory 1002 may alternatively be a storage device separate from the processor 1001. The processor 1001 is respectively connected to the memory 1002 and the brightness detection module 1003 in a communication manner.
The brightness detection module 1003 is used to detect the light intensity of the LED lamp, and may specifically be a light intensity detector or the like.
Those skilled in the art will appreciate that the configuration of the device shown in fig. 1 is not intended to be limiting of the device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a parameter adjustment program may be included in the memory 1002, which is a readable storage medium. In the apparatus shown in fig. 1, the processor 1001 may be configured to call the parameter adjustment program stored in the memory 1002 and perform operations of relevant steps of the LED lamp control parameter adjustment method in the following embodiments.
The invention also provides an LED lamp control parameter adjusting method.
Referring to fig. 2, a first embodiment of the LED lamp control parameter adjusting method according to the present invention is provided, where the LED lamp control parameter adjusting method includes:
step S10, when the LED lamp is driven according to the preset current, obtaining the current luminous first brightness of the LED lamp;
the magnitude of the preset current can be set according to actual requirements. The LED lamp is driven by adopting preset current, the LED lamp emits light under the control of preset brightness control parameters, at the moment, the brightness detection module is adopted to detect the luminous intensity of the LED lamp, and the data detected by the brightness detection module is acquired as the first brightness.
Step S20, determining a first current corresponding to the first brightness;
the calculation method for calculating the corresponding first current according to the first brightness may be different according to different chips or different LED lamps. The first current is specifically a theoretical value of current corresponding to the first brightness of the LED lamp. The different first luminances correspond to different first currents.
Step S30, determining an adjusting parameter according to the preset current and the first current;
the adjusting parameter is specifically a characteristic value of the difference between the preset current and the first current. Specifically, a ratio between a difference between the preset current and the first current and the preset current is used as an adjustment parameter, and a ratio between the first current and the preset current may also be used as an adjustment parameter.
In this embodiment, in order to adjust a preset brightness control parameter more accurately based on an adjustment parameter, a difference between the preset current and the first current is determined; and determining the adjusting parameter according to the ratio of the difference value to the preset current. For example, the following formula may be used to calculate the tuning parameters:
wherein the LEDratioTo adjust the parameters, ItargetFor a predetermined current, ImeasIs a first current.
And step S40, adjusting the preset brightness control parameter of the LED lamp according to the adjustment parameter.
The preset luminance control parameter mainly refers to a stored value in a register. In particular, in a register of a PWM-based controlled LED lamp, different stored values represent different brightness levels. The duty ratio of the pulse current input into the LED lamp can be adjusted based on the stored value of the register, so that the brightness of the LED lamp can be adjusted.
And adjusting the preset brightness control parameter according to the adjustment parameter, and taking the adjusted result as a new preset brightness parameter and storing the new preset brightness parameter in a register. For example, when the preset brightness control parameter is 127, the LEDcal＝LEDratio127+127, wherein the LEDcalAnd controlling parameters for the adjusted preset brightness.
In this embodiment, the preset brightness control parameter specifically refers to a brightness control parameter when the LED lamp is turned on. And increasing or decreasing the preset brightness control parameter of the current LED lamp according to the adjustment parameter, so that the actual light-emitting brightness of different LED lamps can reach the same brightness level when the different LED lamps are lightened according to the adjusted preset brightness control parameter. For example, when the lamp a and the lamp B are turned on, the luminance levels of the lights need to reach the luminance level of 127, the preset luminance control parameters before the lamp A, B is adjusted are all 127, and when the lamp a is turned on according to the preset luminance control parameters, the actual luminance levels of the lamp A, B may not be 127 and have a difference; after the preset brightness control parameter is adjusted based on the adjustment parameter, the preset brightness control parameter stored in the lamp a register is adjusted to 124, the preset brightness control parameter stored in the lamp B register is adjusted to 126, and when A, B lamps are respectively lighted according to the adjusted brightness control parameters, the actual luminous intensities of both lamps can reach the brightness level 127.
If the LED lamp has a plurality of preset brightness control parameters, each preset brightness control parameter can be synchronously adjusted according to the parameter adjusting parameters.
The method for adjusting the control parameter of the LED lamp, provided by the embodiment of the invention, comprises the steps of obtaining first brightness corresponding to the brightness of the LED lamp when the LED lamp is driven according to the preset current, determining the first current corresponding to the first brightness, determining the adjustment parameter according to the first current and the preset current, and adjusting the preset brightness control parameter of the LED lamp according to the determined adjustment parameter. In the method, because the difference between the actual brightness and the preset brightness of the LED lamp can reflect the brightness deviation of the LED lamp caused by materials, assembly and other factors, the accurate adjustment of the preset brightness control parameter of the LED lamp can be realized based on the adjustment parameter determined by the preset current and the first current, and the brightness of different LED lamps can be consistent when the different LED lamps operate according to the corresponding preset brightness control parameter.
Further, based on the first embodiment, a second embodiment of the LED lamp control parameter adjusting method is provided. In a second embodiment, the LED lamp is a tri-color LED lamp having a first color channel, a second color channel, and a third color channel. Each color channel of the LED lamp correspondingly emits color light of one color. When the three color channels are simultaneously opened, the LED lamp can emit different color lights through the mixing of three color lights with different brightness. Specifically, here, the first color, the second color, and the third color are red, green, and blue, respectively. In other embodiments, the first color, the second color and the third color can be set to other colors according to actual conditions. Referring to fig. 3, the step S10 includes:
step S11, when the preset current is input into the first color channel, acquiring a first brightness parameter of the LED lamp; when the preset current is input into the second color channel, acquiring a second brightness parameter of the LED lamp; when the preset current is input into the third color channel, acquiring a third brightness parameter of the LED lamp;
it should be noted that the first color channel, the second color channel, and the third color channel are opened individually. For example, when the first brightness parameter is obtained, the LED lamp only emits the colored light of the first color, and the second color channel and the third color channel are closed. The first luminance parameter, the second luminance parameter, and the third luminance parameter can be obtained by referring to the first embodiment specifically, which is not described herein again.

step S13 of regarding the first current parameter, the second current parameter, and the third current parameter as the first current; the step S20 includes:
step S21, determining a first adjusting parameter according to the first current parameter and the preset current, determining a second adjusting parameter according to the second current parameter and the preset current, and determining a third adjusting parameter according to the third current parameter and the preset current;
in this embodiment, the adjustment parameter corresponding to each color channel is determined according to the specific implementation manner in the first embodiment, which is not described herein again.
The step S30 includes:
step S31, adjusting a first preset brightness control parameter corresponding to the first color channel according to the first adjustment parameter, adjusting a second preset brightness control parameter corresponding to the second color channel according to the second adjustment parameter, and adjusting a third preset brightness control parameter corresponding to the third color channel according to the third adjustment parameter.
According to the requirement of the luminous color of the three-color LED lamp, different color channels correspondingly have different preset brightness control parameters. In this embodiment, the preset brightness control parameter corresponding to each color channel is determined according to the specific implementation manner in the first embodiment, which is not described herein again.
After the preset brightness control parameters corresponding to the three color channels are adjusted, when different LED lamps emit light according to the preset brightness control parameters corresponding to the three color channels, the light-emitting colors and the light-emitting brightness are the same.
Specifically, the first color channel, the second color channel, and the third color channel are respectively defined as an R channel, a G channel, and a B channel, the preset current is 20, and the preset brightness control corresponding to each color channel is performed127, the first current parameter corresponding to the first brightness detected by the R channel is 21, the second current parameter corresponding to the second brightness detected by the G channel is 20, and the third current parameter corresponding to the third brightness detected by the B channel is 18.6, the first adjustment parameter LED is adjustedratio_redA second adjusting parameter LEDratio_greenAnd a third adjustment parameter LEDratio_blueCan be calculated by the following formula;
the brightness control parameter LED after the R channel is adjusted can be obtained by correspondingly calculating the following formula based on the obtained first adjustment parameter, the second adjustment parameter and the third adjustment parametercal_redBrightness control parameter LED after G channel adjustmentcal_greenAnd brightness control parameter LED after B channel adjustmentcal_blue：
LEDcal_red＝-0.05*127+127＝120.65≈121；
LEDcal_green＝0*127+127＝127；
LEDcal_blue＝0.07*127+127＝135.89≈136。
In this embodiment, the preset brightness control parameters corresponding to the three color channels of the three-color lamp are all calibrated according to the above manner, so that the preset brightness control parameters of the color LED lamp are accurately adjusted, and when different color LED lamps operate according to the corresponding preset brightness control parameters, the brightness and the color of the emitted light can be consistent.
Further, based on the second embodiment, a third embodiment of the LED lamp control parameter adjusting method is provided. In the third embodiment, referring to fig. 4, after the step S30, the method further includes:
step S40, obtaining a first preset luminance threshold corresponding to the first color channel, a second preset luminance threshold corresponding to the second color channel, and a third preset luminance threshold corresponding to the third color channel;
here, the first preset luminance threshold, the second preset luminance threshold, and the third preset luminance threshold are maximum values that cannot be exceeded, respectively, limited by the preset luminance control parameters of the three color channels. Specifically, before the adjustment, the first preset brightness threshold, the second preset brightness threshold, and the third preset brightness threshold are brightness level values corresponding to the maximum brightness, which are generally 255.
Step S50, adjusting the first preset brightness threshold, the second preset brightness threshold, and the third preset brightness threshold according to the first adjustment parameter, the second adjustment parameter, and the third adjustment parameter.
According to the quantity relationship (such as the size relationship, the proportional relationship and the like) among the first adjusting parameter, the second adjusting parameter and the third adjusting parameter, respectively determining the adjusting values corresponding to the first preset brightness threshold, the second preset brightness threshold and the third preset brightness threshold, and respectively and correspondingly adjusting the first preset brightness threshold, the second preset brightness threshold and the third preset brightness threshold according to the determined adjusting values.
Specifically, referring to fig. 5, step S50 includes:
step S51, determining a target adjustment parameter among the first adjustment parameter, the second adjustment parameter, and the third adjustment parameter;
one of the first adjustment parameter, the second adjustment parameter and the third adjustment parameter can be selected as a target adjustment parameter according to a preset rule. In this embodiment, the parameter with the largest value among the first adjustment parameter, the second adjustment parameter, and the third adjustment parameter is used as the target adjustment parameter. Based on the three tuning parameters-0.05, 0, and 0.07 determined in the above embodiment, 0.07 may be used as the target tuning parameter.
Step S52, determining the first adjustment value according to the target adjustment parameter and the first adjustment parameter, determining the second adjustment value according to the target adjustment parameter and the second adjustment parameter, and determining the third adjustment value according to the target adjustment parameter and the third adjustment parameter;
specifically, a first adjustment value is determined according to a difference value between the target adjustment parameter and the first adjustment parameter, a second adjustment value is determined according to a difference value between the target adjustment parameter and the second adjustment parameter, and a third adjustment value is determined according to a difference value between the target adjustment parameter and the third adjustment parameter. Specifically, the first adjustment value is 0.07- (-0.05) 0.12, the second adjustment value is 0.07-0.07, and the third adjustment value is 0.07-0.07.
Step S53, adjusting the first preset luminance threshold according to the first adjustment value, adjusting the second preset luminance threshold according to the second adjustment value, and adjusting the third preset luminance threshold according to the third adjustment value.
Defining the adjusted first preset brightness threshold value as LED PWMmax limiter_RAnd the adjusted second preset brightness threshold value is defined as LED PWMmax limiter_GAnd the adjusted third preset brightness threshold is defined as LED PWMmax limiter_BThen, the first preset luminance threshold, the second preset luminance threshold, and the third preset luminance threshold may be calculated by the following formulas:
LED PWMmax limiter_R＝255-255*0.12＝224.4≈224；
LED PWMmax limiter_G＝255-255*0.07＝237.15≈237；
LED PWMmax limiter_B＝255-255*0＝255。

The threshold values of the other two channels are adjusted based on the adjustment parameter corresponding to the channel with the largest adjustment amplitude, so that the accuracy of the color of the colored light which is coordinately emitted by the three colors can be ensured, and especially, the purity of white light formed by mixing the colored light with the maximum brightness through the three color channels can be ensured.

The memory 2002 may alternatively be a storage device separate from the processor 2001 described previously.

And step S400, judging whether the brightness of each LED lamp is consistent or not according to the brightness value.
When the acquired brightness values are all in a preset brightness interval (can emit light according to the requirements of the LED lamps), the light-emitting brightness of the LED lamps can be considered to be consistent, and when the acquired brightness values are outside the preset brightness interval, the light-emitting brightness of the LED lamps corresponding to the brightness values can be considered to be inconsistent with the light-emitting brightness of other lamps.

The preset range can be set according to actual requirements. When the number of the LED lamps to be detected is more than two, the difference value of the brightness values corresponding to two-two calculation is used as the brightness difference, when all the obtained brightness differences are within the preset range, the brightness of the LED lamps to be detected can be considered to be consistent, and when the brightness difference exists in the obtained brightness differences and exceeds the preset range, the brightness of the LED lamps to be detected can be considered to be inconsistent.
