Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated。
Fig. 1 show the photochromic appraisal procedure schematic flow sheet of a kind of Landscape Lighting that the embodiment of the present invention 1 provides。According to Fig. 1, this appraisal procedure comprises the steps:
Step A: the illumination target in Landscape Lighting region is carried out reflection spectrum curve test, it is thus achieved that the reflection spectrum curve of this illumination target；
Step B: the reflection spectrum curve according to the spectrum of lighting source each in data base and described illumination target, what calculate described illumination target each lighting source in the database irradiates the lower colourity presented；
Step C: irradiate the lower colourity presented according to described illumination target each lighting source in the database, reference spectra during using the spectrum corresponding to the colourity that is within the scope of the first default chroma reference as the lighting source selecting described illumination target。
In above steps, step A is the basic steps of the present invention, its objective is as obtaining the illumination target reflectance to the lighting source of different wave length。When carrying out reflection spectrum curve test, illumination target is classified by color, the illumination target belonging to same class color is divided into a class, and all kinds of illumination target are carried out reflection spectrum curve test。Then, the weight of the reflection spectrum curve test result that the area proportion in described Landscape Lighting region is all kinds of illumination target is accounted for all kinds of illumination target, the reflection spectrum curve test result of all kinds of illumination target is weighted average computation, and sue for peace, thus obtain the reflection spectrum curve of this illumination target。When all kinds of illumination target carry out reflection spectrum curve test, available consistent to illumination target colourity tinctorial pattern replaces corresponding illumination target to test。
Lighting source in step B includes high-pressure mercury lamp, Metal halogen lamp, LED or fluorescent lamp etc.。Fig. 6 illustrates tinctorial pattern chroma curve under natural light and conventional lighting source irradiate。Fig. 7 is tinctorial pattern chroma curve under the Gauss distribution type spectroscopic light source of different peak wavelengths and FWHM irradiates。The illumination target with different reflection spectrum curve can be indicated with different tinctorial patterns。Further, it is also possible to directly select typical construction landscape, sculpture view, plants landscape etc. as tinctorial pattern, it is used for carrying out reflection spectrum curve and tests to obtain its reflection spectrum curve。Tinctorial pattern represents illumination target corresponding with this tinctorial pattern color in Landscape Lighting region, and different tinctorial patterns represents the illumination target with different reflection spectrum curve。How many decisions according to the colour type of illumination target of the quantity of tinctorial pattern。Various conventional light source and there is the Gauss distribution type spectroscopic light source of different peak wavelength and FWHM represent the lighting source of different spectrum。Various conventional light source and there is chromatic value that when the Gauss distribution type spectroscopic light source of different peak wavelength and FWHM irradiates different tinctorial pattern, tinctorial pattern presents once it is determined that, there is the colourity that the illumination target of different reflection spectrum curve presents under the lighting source irradiation with different spectrum and determine that。There is the colourity that the illumination target of different reflection spectrum curve presents under the lighting source with different spectrum irradiates can be stored in data base, corresponding relation between the colourity that the combination of the spectrum of formation lighting source and the reflection spectrum curve of illumination target and illumination target present under this lighting source irradiates, for reference to comparison。
In step C, the establishing method of the first chroma reference scope is as follows:
Reflection spectrum curve according to described illumination target calculates the colourity that described illumination target presents under the standard light source that CIE standard illuminants is corresponding is irradiated, and using this colourity as the first standard colorimetric；
Reflection spectrum curve according to described illumination target calculates the colourity that described illumination target presents under different Gauss distribution type spectroscopic light sources irradiate, and sets up the corresponding relation between the colourity that the peak wavelength of Gauss distribution type spectroscopic light source and the combination of FWHM and illumination target present under this Gauss distribution type spectroscopic light source irradiates accordingly；
From described corresponding relation, select the colourity that combination equal for FWHM is corresponding, and determine therefrom that the chromaticity range that described illumination target presents under the Gauss distribution type spectroscopic light source of each FWHM irradiates；
The color difference typical value of colourity that described illumination target presents under the Gauss distribution type spectroscopic light source of each FWHM irradiates and described first standard colorimetric is calculated according to described illumination target chromaticity range of presenting under the Gauss distribution type spectroscopic light source of each FWHM irradiates；
According to the default aberration with described first standard colorimetric, using the chromaticity range corresponding to the color difference typical value minimum with this aberration difference as the first chroma reference scope。
Here, can by D65Standard light source is used for calculating the colourity that illumination target presents under this standard light source is irradiated as the standard light source that CIE standard illuminants is corresponding。Select different chromaticity range as the first chroma reference scope, and select light source can realize the illuminating effect that illumination target is different according to this term of reference。
Fig. 2 show the schematic flow sheet of the photochromic appraisal procedure of another kind of Landscape Lighting that the embodiment of the present invention 2 provides。According to Fig. 2, the method includes:
Step A: the illumination target in Landscape Lighting region is carried out reflection spectrum curve test, it is thus achieved that the reflection spectrum curve of this illumination target；
Step D: the lighting source of preliminary election is carried out spectral power distribution test, it is thus achieved that the spectrum of the lighting source of preliminary election；
Step E: according to the corresponding relation between the colourity that the combination of the spectrum of the lighting source prestored in the reflection spectrum curve of described illumination target, the spectrum of the lighting source of preliminary election and data base and the reflection spectrum curve of illumination target and illumination target present under this lighting source irradiates, it is determined that the colourity that described illumination target presents under the irradiation of the lighting source of preliminary election。
In above-mentioned steps A, D, E, step A is identical with the step A in the schematic flow sheet of the photochromic appraisal procedure of Landscape Lighting that embodiment 1 provides。In step D, the lighting source of preliminary election generally selects from conventional lighting source。Although saying from theory, light source has multiple, but conventional lighting source generally only includes high-pressure mercury lamp, Metal halogen lamp, LED or fluorescent lamp etc.。The purpose of step D is in that to determine the spectrum of the lighting source of institute's preliminary election, in order to the follow-up spectrum according to this light source calculates the colourity that illumination target presents under this light source irradiation。
Step B in the schematic flow sheet of the photochromic appraisal procedure of Landscape Lighting that step E provides with embodiment 1 in like manner, does not repeat them here。
Being differing primarily in of the photochromic appraisal procedure of Landscape Lighting that the photochromic appraisal procedure of Landscape Lighting that embodiment 2 provides provides with embodiment 1, the colourity that embodiment 1 can present under the irradiation of the light source of different spectrum according to illumination target selects the reference spectra of the lighting source of this illumination target, and embodiment 2 can calculate, according to the spectrum of the lighting source of preliminary election, the colourity that illumination target presents under the lighting source of this spectrum。The above-mentioned two photochromic appraisal procedures of set can be incorporated into and collectively form a new photochromic appraisal procedure, make this photochromic appraisal procedure have more multi-functional。
Fig. 3 show the schematic flow sheet of the photochromic appraisal procedure of another kind of Landscape Lighting that embodiment 3 provides。The method is formed by increasing step F further after the step E in the photochromic appraisal procedure schematic flow sheet of Landscape Lighting that provides in embodiment 2。Step F is: the colourity described illumination target presented under the irradiation of the lighting source of preliminary election and the second chroma reference scope compare, and judge that the illuminating effect that described illumination target is produced by the lighting source of institute's preliminary election is that reproduction effects still reinvents effect according to comparative result；If the colourity presented is within the second chroma reference scope, then the illuminating effect that described illumination target is produced by the lighting source of institute's preliminary election is reproduction effects；If the colourity presented is outside the second chroma reference scope, then the illuminating effect that described illumination target is produced by the lighting source of institute's preliminary election is for reinventing effect。Step F will be determined in step E that the colourity that the illumination target drawn presents under the irradiation of the lighting source of preliminary election compares with the second chroma reference scope of presetting, so that it is determined that the character that the lighting source of this preliminary election is to the illuminating effect that described illumination target produces。
The second chroma reference scope involved in step F is different from aforesaid first chroma reference scope。Second chroma reference scope is for determining that the illuminating effect that illumination target produces is belonged to reproduction effects and still reinvents effect by lighting source。Here, reproduction effects refers to, the repeatability of lighting source comparison improving eyesight target colourity。Reinvent effect and refer to the lighting source remoldability to illumination target colourity。When lighting source is irradiated in illumination target, the colourity that the colourity that illumination target presents presents under white light source irradiates with this illumination target differs more little, represent that this lighting source is more good to the repeatability of illumination target colourity, the reduction degree of illumination target colourity is more high, the colourity that the colourity that illumination target presents presents under white light source irradiates with this illumination target differs more big, then represent that this lighting source is more good to the remoldability of illumination target colourity, the change of illumination target colourity is more big。
In step F, the establishing method of the second chroma reference scope is as follows:
Reflection spectrum curve according to described illumination target calculates the colourity that described illumination target presents under the standard light source that CIE standard illuminants is corresponding is irradiated, and using this colourity as the second standard colorimetric；
Chromaticity range is determined according to the default maximum allowable aberration with this second standard colorimetric, and using this chromaticity range as the second chroma reference scope。
Here, can by D65Standard light source is used for calculating the colourity that illumination target presents under this standard light source is irradiated as the standard light source that CIE standard illuminants is corresponding。When setting maximum allowable aberration, a suitable value can be determined according to the height that the repeatability of illumination target colourity is required by lighting source。When being in this chromaticity range, then lighting source belongs to the light source that this illumination target has repeatability, its comparison improving eyesight target colourity has good repeatability, its illuminating effect that described illumination target is produced is reproduction effects, otherwise, lighting source belongs to the light source that this illumination target has remoldability, and its comparison improving eyesight target colourity has good remoldability, and its illuminating effect that described illumination target is produced is for reinventing effect。
