Meter requires, then is matched confirmation.It confirms the result is that the cover board of known color drift combines the diaphragm of the drift of the known color on pasting
Final color drift is color drift value corresponding to the cover board color of design requirement.
It is as described above, before executing step 1, it would be desirable to first test the color Cx for determining lid surfaceIt surveys', CyIt surveys'
Or λDom is surveyedThen ' enters back into step 1；
Color drift Δ Cx, Δ Cy or the Δ λ of cover board can be known after executing the step onedomAnd the color Cx of lid surfaceIt surveys',
CyIt surveys' or λDom is surveyedColor Cx ', Cy ' or the λ of ' and customer requirementdomThe discrepancy delta Cx of 'Difference、ΔCyDifferenceOr Δ λDom is poor；Calculation formula
It is as follows:
ΔCxDifference=Cx '-CxIt surveys', Δ CyDifference=Cy '-CyIt surveys', Δ λDom is poor=λdom'-λDom is surveyed'；
According to the discrepancy delta Cx of the color of lid surface and the color of customer requirementDifference、ΔCyDifferenceOr Δ λDom is poorStep 2 is executed, is made
Discrepancy delta CxDifference=Δ Cx ', Δ CyDifference=Δ Cy ' or Δ λDom is poor=Δλdom'；
Step 3 is finally executed by confirming color drift value corresponding to the cover board color of design requirement to determine the lid of customer requirement
Plate color；Calculation formula is as follows:
Cx '=CxIt surveys'+Δ Cx '=Cx+ Δ Cx+ Δ Cx ',
Cy '=CyIt surveys'+Δ Cy '=Cy+ Δ Cy+ Δ Cy ',
λdom'=λDom is surveyed'+Δ λdom'=Δ λdom+Δλdom +ΔλDom is surveyed'.
As stated above, it selects the diaphragm of not homochromy drift to go to change the color of lid surface, obtains the color needed for us
After design requirement, then color drift value Δ Cx, Δ Cy or Δ λ by changing cover boarddomOr color Cx, Cy or λ of LEDdomAnti- mistake
To instruct us to carry out light color design.
It is assumed that customer requirement color is Cx '=0.3, '=0.3 Cy, the LED color chromaticity coordinates for designing or selecting at the beginning
For Cx=0.29, Cy=0.28, the color drift of cover board is Δ Cx=0.05, Δ Cy=0.03, is computed or tests and obtains lid surface
Color be Cx '=0.29+0.05=0.34, '=0.28+0.03=0.31 Cy is unsatisfactory for customer requirement, we are by covering at this time
Increasing color drift below plate is Δ Cx '=- 0.04, and the color of Δ Cy '=- 0.01 floats diaphragm, can be obtained Cx '=0.29-0.04+0.05=
0.3, Cy '=0.28-0.01+0.03=0.3, meets the requirements of the customers, and then send color light model machine directly to client, wait clients with
After vehicle light carries out matching approval, then return color drift value Δ Cx, Δ Cy or the Δ λ for changing cover board to the previous stepdomOr the face of LED
Color Cx, Cy or λdomThese parameters, we just do not spend the LED for using different chromaticity coordinates instead or change cover board in this way
Color drift value (adjustment ink, use the cover board of different materials instead) obtain the requirement that the color of client requires to obtain client,
Meanwhile adjustment color is gone in this way, the light that with quick Fabrication light model machine, can quickly cope with client needs, i.e.,
Client's light is set to have altered, we can also quickly make light model machine using color drift diaphragm and be given to client's confirmation, so significantly
The time of light setting and confirmation is shortened, project process will not be delayed.
After the color design for completing light by above-mentioned method, the limit model machine of color is produced, internal entries team is given
And client confirms.
Make color limit model machine: it is assumed that client's color requires to be '=0.3 ± 0.03, Cy Cx '=0.3 ± 0.03, I
Can also using color float diaphragm come make color the upper limit, it is middle limit and lower limit model machine, operating method be, first test select
The color of one of state floats diaphragm, for example above-mentioned color drift is Δ Cx '=- 0.04, and the color of Δ Cy '=- 0.01 floats diaphragm,
It is fabricated to limit '=0.3 model machine Cx '=0.3, Cy in color, then using color drift as Δ Cx '=- 0.04, Δ Cy ''s=- 0.01
Color float diaphragm on the basis of, select color drift be respectively Δ Cx '=- 0.07, Δ Cy '=- 0.04 and Δ Cx '=- 0.01, Δ Cy '=
0.02 color floats diaphragm, make respectively '=0.27 '=0.27, Cy color lower limit model machine Cx and color upper limit model machine Cx '=
0.33, Cy '=0.33, or select multiple color drift diaphragms with not homochromy drift simultaneously to obtain.Color floats the not homochromy of diaphragm
Drift is as shown in the following table 2 and table 3:
