When described target illumination pattern is for presetting light filling pattern, carries out reduction with the chromaticity coordinates value of default weight coefficient to described initial reflectance spectrum and obtaining target color coordinates value.
Because reverberation exists the decay of color relative to irradiating light, the reverberation namely obtained based on a certain irradiation light photochromic obviously weak as the irradiation light on its basis.Presetting with under optical mode, increase can carried out by the default chromaticity coordinates value of weight coefficient to initial reflectance spectrum and obtain target color coordinates value, thus overcome the decay of aforementioned color.But, under default light filling pattern, because default light filling pattern required irradiation light should be contrary with the color of irradiated object, then need to carry out reduction with the chromaticity coordinates value of default weight coefficient to described initial reflectance spectrum and obtain target color coordinates value.
Aforementioned default weight coefficient artificially can be preset according to presetting the degree of optical mode and default light filling pattern of sharing the same light, and presets share the same light optical mode and the default weight coefficient needed for default light filling pattern and can be set as same, also can be set as difference.
S33, obtain target color information according to described target color coordinates value.
In present pre-ferred embodiments, opponent-color coordinates value can carry out the component relative intensity of the RGB be converted to for embodying color of object, to carry out changing the process obtaining its corresponding chromaticity coordinates value contrary with the colouring information of the initial reflection light obtained by colour recognition module 100, do not repeat at this.
S40, driver module 700 are according to the drive control signal received and carry out spectrum adjustment operation to light source module 800, and namely driving light source module 800 sends target detected light corresponding to target color information.
In present pre-ferred embodiments, obtain target P WM signal according to described target color information, then control described light source module 800 to irradiated object projection target detected light by described target P WM signal.
S50, colour recognition module 100 obtain the colouring information of the target reflecting light that described irradiated object generates based on described target detected light.
In present pre-ferred embodiments, the colouring information of based target reverberation is obtained, namely for embodying the component relative intensity of the RGB of color, i.e. rgb value by this colour recognition module 100, this is technology well known to those of ordinary skill in the art, does not repeat at this.
S60, judge that the colour-difference of described initial reflection light and target reflecting light is whether in pre-set color difference scope, if so, performs step S70, if not, performs step S80
In present pre-ferred embodiments, judge that the colour-difference of the two is whether in pre-set color difference scope by the difference of the chromaticity coordinates value of initial reflection light and target reflecting light.Wherein, the difference that described pre-set color difference scope comprises the described color coordinate values of initial reflection light and the color coordinate values of target reflecting light is less than or equal to 0.001.
Certainly, pre-set color difference scope is not limited to the scope of aforementioned 0.001, and its concrete numerical value can set according to demand, does not repeat at this.
S70, control described lighting module 700 keep projection described target detected light.
Theoretical according to chromatics, any one irradiates light and is be mutually related between the reverberation generated based on this irradiation light, then can be extrapolated the color in-scope irradiating light by the color obtaining reverberation.Because the color of irradiating light cannot gather, whether the colour-difference that naturally also cannot calculate initial scout light and target detected light is close, when the colour-difference of initial reflection light and target reflecting light is in pre-set color difference scope, obviously can infer that the colour-difference of initial scout light and target detected light is also very close.
No matter be preset with optical mode or default light filling pattern, obtaining in the process of color of object by step S30, color of object is close all the time towards the color of the irradiation light coordinated most with irradiated object color, the colour-difference of initial scout light and target detected light be also very close to time, show that adjacent twice adjustment for detected light there is no color change for detected light, can show that detected light is adjusted to the right place, now the color of detected light and the color of irradiated object are coordinated most.Therefore, the target that meets the requirements detected light can as the irradiation light irradiated to irradiated object.
S80, colouring information according to obtained target reflecting light, upgrade the colouring information of described initial scout light, and return step S10.
When the colour-difference of described initial reflection light and target reflecting light is not in preset range, show in the colour-difference of initial scout light and target detected light very not close, namely detected light is not adjusted to the right place, then need with the colouring information of current obtained target reflecting light to upgrade the colouring information of initial scout light, and return step S10 to S60, more fresh target detected light is carried out, until obtain the conclusion of colour-difference in preset range of initial reflection light and target reflecting light in step S60 by wherein step S30.
The technical scheme of the control method of the lighting device provided from above present pre-ferred embodiments, present pre-ferred embodiments is by obtaining a rear detected light according to the reverberation of last detected light, when the colour-difference of the reverberation of former and later two detected light is less than pre-set color difference scope, after controlling lighting device, a detected light projects irradiated object.How the color realizing no matter irradiated object changes, and when even color change is very trickle, also automatically can obtain the detected light of color and its coordination.
Above-described instantiation; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
