In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions in the embodiments of the present invention will be clearly described in conjunction with the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
First embodiment:
in order to solve the problem of poor effectiveness of adjustment control of the multispectral light source provided in the related art, the embodiment provides a light source control method, which is applied to a reading lamp provided with the multispectral light source and a display component. As shown in fig. 1, which is a basic flow chart of a light source control method provided in this embodiment, the light source control method provided in this embodiment includes the following steps:
Specifically, in this embodiment, the different spectrum light sources may be monochromatic spectrum light sources or mixed spectrum light sources.
Fig. 2 is a schematic diagram of color gamut division provided in this embodiment, which describes a color gamut division manner of an RGBW light source on a CIE chromaticity diagram, where the chromaticity diagram is divided into a BGW color gamut, an RGW color gamut, and a BWR color gamut, and each chromaticity value in each color gamut corresponds to a uniquely determined spectrum. For the color gamut division in this embodiment, the color gamuts formed by the light sources with multiple colors corresponding to the chromaticity diagram may not intersect each other, or the color gamuts formed by the light sources with multiple colors corresponding to different brightness levels in the color gamut may not intersect each other.
It should be noted that, through the color gamut division in this embodiment, the metamerism phenomenon can be effectively avoided, that is, multiple spectrum implementation schemes under the same chromaticity cannot occur; in addition, each independent color gamut is smooth and continuously changed, and the performance correspondingly represented at the junction of different color gamuts is also continuously changed, so that the effect of subsequent performance representation can be improved; in addition, each partition of the embodiment has simple characterization and is easier to express in a functional form.
And 103, according to the relative performance characteristic model and the chromaticity information, the absolute performance characteristic model, the luminosity information and the chromaticity information, performing corresponding visual representation on the illumination performance information of the target environment on each independent color gamut on the chromaticity diagram, and outputting visual representation images through the display assembly.
Specifically, in this embodiment, the relative performance feature model is constructed based on a first association relationship between spectral feature information and chromaticity information of the multispectral light source, and a second association relationship between the spectral feature information and ambient lighting performance information; the absolute performance characteristic model is constructed based on a third association relation between the spectral characteristic information and the luminosity information, and the first association relation and the second association relation.
In this embodiment, the model building is specifically explained by taking a relative performance feature model as an example, and in this embodiment, the first association relationship may be expressed by a functional relationship (x, y) =f (PW, FWHM), where (x, y) is a chromaticity value, PW is a peak wavelength, and FWHM is a half width. For the selected composite light source, the composite light source can be divided into m spectrums with PW and FWHM, wherein m is more than or equal to 2, and (x) m ,y m )＝f(PW m ,FWHM m ) Wherein (x) m ,y m ) Refers to the corresponding chromaticity value of the mth spectrum, PW m 、FWHM m Refer to PW, FWHM of the mth spectrum. In addition, the second association relationship may be expressed by a functional relationship (L, S, H) =f (PW, FWHM), where L is luminance/brightness, S is saturation/purity/chroma, H is hue/hue, PW is a peak wavelength, and FWHM is a half width. For the selected composite light source, the composite light source can be divided into m spectrums with PW and FWHM, wherein m is more than or equal to 2, and (L, S, H) =f (PW m ,FWHM m )。
Further, the relative performance characteristic model of the present embodiment may employ a functional relationship p=f (x, Y, E n ) And (3) representing the performance evaluation information of the light source, wherein P is chromaticity coordinates, x and Y are brightness, E is an environmental characteristic parameter, n is the parameter influence formed by the nth environmental characteristic, the function model can be used for various color gamut spaces, and the corresponding function expression can be converted into the corresponding chromaticity space.
In addition, the relative performance feature model of the present embodiment may also take the form of a functional relationship p=f (L, S, H), where P is the light source performance evaluation information, L is the luminance/brightness, S is the saturation/purity/chroma, and H is the hue/hue.
Fig. 3 is a schematic diagram of visual representation of environmental illumination performance provided in this embodiment, which describes visual representation of spectral reflection radiation efficiency corresponding to an object irradiated by an RGBW light source, wherein a square block diagram in the figure is illustrated as a color representation of the object to be illuminated, and a right strip diagram in the figure is illustrated as a color representation of the spectral reflection radiation efficiency at different values.
It should be noted that the ambient lighting performance information of the present embodiment may include: illuminance, brightness, contrast, photochromic contrast, glare, comfort, health effects, preference, and blue light injury effects.
And 104, when a control instruction input for a target color gamut range in the visual representation image is received, referring to the luminosity information and the chromaticity information corresponding to the target color gamut range, and controlling the corresponding spectrum channels of the multispectral light source to carry out light color adjustment.
Specifically, in this embodiment, the performance represented by the different color gamut areas on the performance visual representation image is correspondingly different, in practical application, a user may interact with the display component, trigger a control instruction to a specific color gamut range on the visual representation image, then the reading lamp may obtain corresponding light and chromaticity information according to the acting area of the control instruction, and then control the corresponding spectrum channel of the light source to adjust the absolute intensity proportion and the relative intensity proportion by taking the information as a reference. Because the light source adjustment control behavior is triggered after the user has accurate cognition on the environment illumination performance of the light source, quantitative optimization of specific performance is performed, and therefore the effectiveness of light source adjustment control is ensured.
In an optional implementation manner of this embodiment, before the step of performing corresponding visual representation on the target environmental illumination performance information according to the relative performance feature model and the chromaticity information, and the absolute performance feature model and the luminosity information and the chromaticity information on the chromaticity diagram, the method further includes: acquiring environment attribute information of the current illumination environment of the reading lamp; the target ambient lighting performance information is selected accordingly from among all types of ambient lighting performance information based on the ambient attribute information.
Specifically, the environmental attribute information of the present embodiment includes: the working surface material optical characteristics, the ambient light information and the orientation information of the irradiation surface relative to the reading lamp, wherein the working surface can be a tabletop in an illumination environment, and the working surface can be the surface of an object such as a book on the tabletop. In practical applications, the performance types required to be focused in different types of lighting environments are different, for example, contrast and comfort are focused in some lighting environments, and brightness and health effects are focused in other lighting environments. Therefore, in the embodiment, corresponding environment illumination performance types required to be concerned are correspondingly acquired aiming at the actual illumination environment, and then the visual representation of the environment illumination performance is performed in a targeted manner, so that the final visual representation result of the performance is ensured to form effective guidance for a user.
In an optional implementation manner of this embodiment, before the step of performing corresponding visual representation on the target environmental illumination performance information according to the relative performance feature model and the chromaticity information, and the absolute performance feature model and the luminosity information and the chromaticity information on the chromaticity diagram, the method further includes: acquiring environment attribute information of the current illumination environment of the reading lamp; the relative performance feature model and the absolute performance feature model are selected accordingly based on the environmental attribute information.
In this embodiment, the first association relationship and the second association relationship of constructing different absolute performance feature models are different, and the first association relationship, the second association relationship and the third association relationship of constructing different absolute performance feature models are different. The embodiment adaptively builds different performance characteristic models according to different lighting environments, and the embodiment can be embodied in the mode that the model building principle is the same, and the values of the correlation coefficients in the models are different. Therefore, the model selected during performance characterization is suitable for different illumination environments, and the accuracy of performance characterization can be effectively ensured.
In an optional implementation manner of this embodiment, before the step of controlling the light color adjustment of the corresponding spectrum channel of the multispectral light source by using the luminosity information and the chromaticity information corresponding to the reference target color gamut range, the method further includes: the visual representation image is divided into a plurality of color gamut ranges for different performance levels according to a classification threshold of the target ambient lighting performance information.
As shown in fig. 4, a schematic diagram of color gamut range division provided in this embodiment is shown, specifically, in practical application, corresponding thresholds of different performance levels may be formulated according to the performance advantages and disadvantages, and then performance characterization values on the visual characterization image may be classified by multiple thresholds, so that the color gamut on the visual characterization image is divided into multiple color gamut ranges, where the multiple color gamut ranges respectively correspond to different performance levels. For example, the gamut range divided by the threshold 1 in fig. 4 corresponds to a high performance level, the gamut range divided by the threshold 2 corresponds to a medium performance level, and the gamut range divided by the threshold 3 corresponds to a low performance level.
Further, in some embodiments, after the step of dividing the visual representation image into the plurality of color gamut ranges for different performance levels according to the classification threshold of the target ambient lighting performance information, the method further includes: invoking color gamut range division results of the visual representation images corresponding to other types of environment illumination performance information; combining the color gamut range division results corresponding to the target environment illumination performance information and the color gamut range division results corresponding to other types of environment illumination performance information to obtain the coincident color gamut ranges with the same performance level; and referring to the coincident color gamut ranges, dividing the visual representation image corresponding to the target environment illumination performance information into a plurality of color gamut ranges again.
Specifically, in practical applications, there may be multiple types of performance of the environmental illumination to be evaluated, and then there are multiple performance characterization results corresponding to the multiple types of performance characterization results, and the color gamut ranges correspondingly divided according to the performance classification threshold are different, as shown in fig. 5, which is another schematic diagram of color gamut range division provided in this embodiment. In this embodiment, considering that, when light source control is performed based on only a single-performance color gamut range division result, one of the light source performance is optimized while the other light source performance is impaired, in specific practice, the color gamut range division result of multiple light source performances is combined, a common color gamut area (i.e., a coincident color gamut range) with multiple performance levels being the same is obtained, and then the color gamut range division is further performed on the performance-representing image of a certain current ambient lighting performance, for example, the performance-representing image of fig. 4 is displayed on the display component, and the high performance level color gamut range is larger than and can completely cover the high performance level color gamut range of the performance-representing image of fig. 5, then the high performance level color gamut range divided by the threshold 1 in fig. 5 is corrected, and then the finally divided high performance level threshold range on the performance-representing image of fig. 4 is the color gamut range with multiple optimal performances, and when the color gamut range is triggered by the user, the collaborative optimization of the multiple ambient lighting performance can be achieved.
Further, in some embodiments, before the step of dividing the visual representation image into the plurality of color gamut ranges for different performance levels according to the classification threshold of the target ambient lighting performance information, the method further includes: acquiring current scene attribute information, wherein the scene attribute information comprises: weather, season, time; determining a performance preference index based on the scene attribute information; the ranking threshold is set accordingly based on the performance preference index.
Specifically, in this embodiment, the lighting scene in the same lighting environment is considered to be dynamically changed, and the lighting conditions are generally different along with the time period change, the seasonal change and the climate change in the day, and then the performance requirements of the user on the brightness, the color temperature, the rhythm change and the like of the lighting environment are also different in adaptability, so that the embodiment determines the classification threshold according to the lighting scene in real time, so as to ensure that the performance classification on the performance visual representation image is more suitable for the actual use requirements, and further realize more accurate light source adjustment control.
In another optional implementation manner of this embodiment, the step of performing corresponding visual representation on the target environmental illumination performance information according to the relative performance feature model and the chromaticity information, and the absolute performance feature model and the luminosity information and the chromaticity information on the chromaticity diagram by using each independent color gamut includes: respectively determining performance evaluation values of each independent color gamut of different types of target environment illumination performance information on a chromaticity diagram according to the relative performance characteristic model and chromaticity information and the absolute performance characteristic model and luminosity information and chromaticity information; calculating comprehensive performance evaluation values of all independent color gamuts according to the evaluation values of the illumination performance information of different types of target environments; and carrying out visual characterization on the whole illumination performance information of different types of target environments based on each independent color gamut of the comprehensive performance evaluation value on the chromaticity diagram.
Specifically, unlike the foregoing embodiments in which the display assembly displays a visual representation of a single ambient lighting performance, the present embodiment achieves a visual representation of a composite ambient lighting performance. In specific practice, the comprehensive performance evaluation value of each color gamut of the chromaticity diagram is calculated based on different performance evaluation values, and specific calculation implementation can be realized in a weighted averaging mode, and then the comprehensive performance evaluation value is characterized on the chromaticity diagram when performance visual characterization is carried out. Therefore, when the color gamut is divided later, the cooperative optimization of the multi-environment illumination performance can be realized in the light source adjustment control according to the performance grade corresponding to each color gamut range divided by the grading threshold, namely the comprehensive performance grade.
According to the light source control method provided by the embodiment of the invention, the luminosity information and the chromaticity information corresponding to each spectrum channel of the multispectral light source are obtained; dividing the color gamut of the multispectral light source into a plurality of independent color gamuts which are not overlapped with each other on the chromaticity diagram corresponding to the multispectral light source; according to the relative performance characteristic model and the chromaticity information, the absolute performance characteristic model, the luminosity information and the chromaticity information, performing corresponding visual representation on the illumination performance information of the target environment on each independent color gamut on a chromaticity diagram, and outputting visual representation images through a display component; when a control instruction input for a target color gamut range in a visual representation image is received, referring to luminosity information and chromaticity information corresponding to the target color gamut range, controlling a corresponding spectrum channel of the multispectral light source to carry out light color adjustment. By implementing the invention, the spectral characteristics of the light source are fully considered, the visual representation is carried out on the light source performance based on the association relation of chromaticity, luminosity and light source performance, and the accurate assessment of the light source performance can be realized, so that effective guidance can be provided for the light source adjustment control.
