Monochromatic LED lamp is stated, the first intrinsic brilliance after obtaining colour mixture；
It returns and executes the step S21, that is, judge the difference between first intrinsic brilliance and the object brightness
Whether in the second preset range.
Target duty ratio is obtained according to first intrinsic brilliance, the object brightness and duty ratio currently entered
Concrete mode is as follows: calculate the ratio K between object brightness and the first intrinsic brilliance, then K=Lm/Ls1, K be object brightness with
Ratio between first intrinsic brilliance, Lm are object brightness, and Ls1 is the first intrinsic brilliance, then PMVm=PMV1 × K, PMV1 are
Duty ratio currently entered, PMVm are target duty ratio, ratio of the K between object brightness and the first intrinsic brilliance.
In technical solution disclosed in the present embodiment, corrected by the circulation to target duty ratio, so that obtained target accounts for
Empty ratio is more accurate.
Referring to Fig. 4, in one embodiment, further comprised the steps of: after the step S20
Step S30 lights each monochromatic LED with each monochromatic LED lamp target duty ratio and calibration electric current
Lamp；
Step S40 each of obtains after lighting the color value of the monochromatic LED lamp, and obtains the color value of each LED light
Between color ratio；
Whether step S50 judges the color ratio in the second preset range；
Step S60, when the color is not than in the second preset range, according to the color ratio and currently entered
Duty ratio updates the target duty ratio of each monochromatic LED；
S30 is returned to step, i.e., each institute is lighted with each monochromatic LED lamp target duty ratio and calibration electric current
State monochromatic LED lamp；
Step S70, when the color ratio is in the second preset range, using duty ratio currently entered as the monochrome
The target duty ratio of LED light.
When light after colour mixture is white light, required red LED lamp, green LED lamp and the corresponding color of blue LED lamp
The ratio of value is 1, when the light after colour mixture is orange-colored light, the ratio of the color value of required red LED lamp and green LED lamp
It is 1, color ratio depends on mixed color demand, and the corresponding color of different blend colors is than different.Second preset range
It is interior to depend on the corresponding color ratio of mixed color, such as when light upon mixing is white light, corresponding second preset range
For [0.95,1.05].
It can determine color value that needs compensate so that the color ratio of each monochromatic LED lamp reaches second according to each color value
In preset range, the offset of target duty ratio is can be obtained in the color value compensated as needed, is accounted for according to the offset to target
Sky realizes the update of target duty ratio than being adjusted.Duty ratio currently entered is currently to light used by monochromatic LED lamp
Duty ratio.
Technical solution disclosed in the present embodiment is adjusted target duty ratio according to color value, so that each monochromatic LED
Mixed color can reach the color of user's needs.
In above-mentioned Fig. 4, step S60 includes:
When the color is not than in the second preset range, the maximum value and minimum value in each color value are obtained；

When the color of lamp, green LED lamp and the corresponding color value of blue LED lamp is compared not within a preset range, red LED lamp pair is obtained
Color value GrayR, the corresponding color value GrayG of green LED lamp and the corresponding color value GrayB of blue LED lamp answered is obtained
Maximum value and minimum value, such as maximum value are GrayR, minimum value GrayB, and adjustment is determined according to GrayR and GrayB
Value, and be adjusted according to adjusted value come the duty ratio PMWr to red LED lamp, and according to adjusted value come to blue LED lamp
Duty ratio PMWb is adjusted.
It can be understood that updating the corresponding monochromatic LED lamp of maximum value and the corresponding list of minimum value according to the adjusted value
The step of color LED light target duty ratio includes:
The adjusted value is subtracted to the target duty ratio of the corresponding monochromatic LED lamp of the maximum value, to update the maximum
It is worth the target duty ratio of corresponding monochromatic LED lamp；
The adjusted value is subtracted to the target duty ratio of the corresponding monochromatic LED lamp of the minimum value, to update the maximum
It is worth the target duty ratio of corresponding monochromatic LED lamp.
In the present embodiment, adjusted value can be the half of maximum color value and the difference of minimum color value, such as red LED
The corresponding color value GrayR of lamp, the corresponding color value GrayG of green LED lamp and the corresponding color value GrayB of blue LED lamp
In, maximum value GrayR, minimum value GrayB, then adjusted value T=(GrayR-GrayB)/2, then the duty ratio of red LED lamp
The duty ratio that PMWr=PMWs1-T, PMWs1 are inputted when being current point shiny red LED light, the duty ratio PMWb=of blue LED lamp
The duty ratio that PMWs2-T, PMWs2 are inputted when being current point sapphirine LED light.Since GrayG is located at centre, then GrayG is put into
Target duty ratio remains unchanged.
It is understood that when monochromatic LED lamp is two, then in the color value of two monochromatic LED lamps, biggish color
Value is maximum value, and lesser color value is minimum value, and specific numerical procedure is specifically repeated no more with reference to the scheme of three LED light.
Concrete scheme present embodiment discloses target duty than adjusting, the program directly according to the maximum value of color value with
And the difference of minimum value is adjusted, calculating process is simple.

Second intrinsic brilliance of monochromatic LED lamp；
Step S90 obtains each monochromatic LED lamp according to object brightness, the second intrinsic brilliance and predetermined current
Target current, so that second intrinsic brilliance of each monochromatic LED lamp and the difference of the object brightness are pre- in third
If in range.
Since input current of the LED light when lighting also will affect the brightness of LED, then need to each monochromatic LED lamp
Electric current is adjusted, so that the difference of the second intrinsic brilliance of each monochromatic LED lamp and the object brightness is default in third
In range, third preset range can be configured as needed.
Offset of the target duty than needs can be determined by the second intrinsic brilliance and object brightness, according to offset
And predetermined current directly obtains target current；Adjustment ratio, root can also be determined according to the second intrinsic brilliance and object brightness
Target current is obtained according to adjustment ratio and predetermined current.
Technical solution disclosed in the present embodiment, according to each according to object brightness, the second intrinsic brilliance and predetermined current
Obtain the target current of each monochromatic LED lamp so that second intrinsic brilliance of each monochromatic LED lamp with it is described
The difference of object brightness guarantees that the brightness of each monochromatic LED lamp can be again in preset range in third preset range.
