Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment:

in order to solve the problem of poor effectiveness of adjustment and 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 schematic diagram of a basic flow of a light source control method provided in this embodiment, the light source control method provided in this embodiment includes the following steps:

step 101, obtaining luminosity information and chrominance information corresponding to each spectral channel of the multispectral light source.

Specifically, in this embodiment, the light sources with different spectrums may be monochromatic light sources, or may be mixed spectrum light sources.

And 102, 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.

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, the chromaticity diagram is divided into a BGW color gamut, an RGW color gamut, and a BWR color gamut, and each color gamut has a color value corresponding to a uniquely determined spectrum. For the color gamut division of the present embodiment, the color gamuts formed by the multiple light color light sources corresponding to the chromaticity diagram may not intersect with each other, or the color gamuts formed by the multiple light color light sources corresponding to different brightness levels in the color volume may not intersect with each other.

It should be noted that by the color gamut division of the embodiment, metamerism can be effectively avoided, that is, a plurality of spectrum implementation schemes under the same chromaticity cannot occur; moreover, each independent color gamut is smoothly and continuously changed, and the performance of corresponding representation at the boundary 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 is simple in representation and is easier to express in a functional form.

And 103, performing corresponding visual representation on the lighting performance information of the target environment in each independent color gamut on the chromaticity diagram according to the relative performance characteristic model and the chromaticity information, and the absolute performance characteristic model and the luminosity information and the chromaticity information, and outputting a visual representation image through the display assembly.

Specifically, in this embodiment, the relative performance characteristic model is constructed based on a first association relationship between spectral characteristic information of the multispectral light source and chromaticity information, and a second association relationship between the spectral characteristic information and ambient lighting performance information; and the absolute performance characteristic model is constructed on the basis of a third correlation between the spectral characteristic information and the luminosity information, the first correlation and the second correlation.

In this embodiment, the first correlation 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 spectrum can be divided into m spectrums with PW and FWHM, wherein m is more than or equal to 2, and the spectrum is formed (x)_m,y_m)＝f(PW_m,FWHM_m) Wherein (x)_m,y_m) Means that the m-th spectrum corresponds to a chromatic value, PW_m、FWHM_mRefers to the PW, FWHM of the mth spectrum. In addition, the second correlation can 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 peak wavelength, and FWHM is half width. For the selected composite light source, m spectra with PW and FWHM can be divided, wherein m is more than or equal to 2, and (L, S, H) is formed as f (PW)_m,FWHM_m)。

Further, the relative performance characteristic model of the embodiment may adopt a functional relationship P ═ f (x, Y, E)_n) And expressing, wherein P is light source performance evaluation information, x and Y are chromaticity coordinates, Y is brightness, E is an environment characteristic parameter, n is a parameter influence formed by the nth environment characteristic, the function model can be various color gamut spaces, and the corresponding function expression can be converted into the corresponding chromaticity space.

In addition, the relative performance characteristic model of the present embodiment may also take the form of a functional relationship P ═ f (L, S, H), where P is light source performance evaluation information, L is luminance/brightness, S is saturation/purity/chroma, and H is hue/hue.

Fig. 3 is a schematic diagram of the visual representation of the ambient lighting performance provided by the embodiment, and describes a visual representation of spectral reflection radiation efficiency corresponding to an object irradiated by an RGBW light source, in which a square box in the diagram is illustrated as a color schematic of the illuminated object itself, and a right long bar in the diagram is illustrated as a color schematic of the spectral reflection radiation efficiency under different values.

It should be noted that the ambient lighting performance information of the present embodiment may include: illumination, brightness, contrast, light-color contrast, glare, comfort, health effects, preference, blue light damage effects.

And 104, when a control instruction input aiming at the target color gamut range in the visual representation image is received, controlling the corresponding spectral channel of the multispectral light source to perform light color adjustment by referring to the luminosity information and the chromaticity information corresponding to the target color gamut range.

Specifically, in this embodiment, the performance represented by different color gamut areas on the performance visualized representation image is correspondingly different, in practical application, a user may interact with the display component to trigger a control instruction to a specific color gamut area on the visualized representation image, and then the reading lamp may obtain corresponding light and chromaticity information according to an action area of the control instruction, and then control the corresponding spectrum channel of the light source to perform absolute intensity ratio and relative intensity ratio adjustment by taking the obtained information as a reference. The light source adjustment control behavior is triggered based on accurate cognition of a user on the environment lighting performance of the light source, quantitative optimization of specific performance is executed, and therefore effectiveness of light source adjustment control is guaranteed.

In an optional implementation manner of this embodiment, before the step of performing corresponding visual representation on the target ambient lighting performance information in each independent color gamut on the chromaticity diagram according to the relative performance characteristic model and the chromaticity information, and the absolute performance characteristic model and the luminosity information and the chromaticity information, the method further includes: acquiring environment attribute information of the current illumination environment of the reading lamp; and correspondingly selecting target ambient lighting performance information from all types of ambient lighting performance information based on the ambient attribute information.

Specifically, the environment attribute information of this embodiment includes: work surface material optical properties, ambient light information, orientation information of the illumination surface relative to the reading light, wherein the work surface may be, for example, a desktop within a lighting environment, and the work surface may be an object surface such as a book on the desktop. In practical applications, different types of lighting environments require different types of performance, such as contrast, comfort, and brightness, health effects. Therefore, in the embodiment, the corresponding type of the ambient lighting performance which needs attention is correspondingly obtained for the actual lighting environment, and then the visual representation of the ambient lighting performance is performed in a targeted manner, so that the final visual representation result of the performance is ensured to form effective guidance for the user.

In an optional implementation manner of this embodiment, before the step of performing corresponding visual representation on the target ambient lighting performance information in each independent color gamut on the chromaticity diagram according to the relative performance characteristic model and the chromaticity information, and the absolute performance characteristic model and the luminosity information and the chromaticity information, the method further includes: acquiring environment attribute information of the current illumination environment of the reading lamp; and correspondingly selecting a relative performance characteristic model and an absolute performance characteristic model based on the environment attribute information.

In this embodiment, the first association relationship and the second association relationship for constructing different relative performance characteristic models are different, and the first association relationship, the second association relationship and the third association relationship for constructing different absolute performance characteristic models are different. The embodiment constructs different performance characteristic models for different lighting environment adaptability, and specifically can be embodied that the model construction principle is the same, and the values of correlation coefficients in the models are different. Therefore, the model selected during performance characterization is suitable for different lighting 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 spectral channel corresponding to the multispectral light source to perform light color adjustment according to the luminosity information and the chromaticity information corresponding to the reference target color gamut, the method further includes: the visual representation image is divided into a plurality of color gamut ranges for different performance levels according to a grading threshold of the target ambient lighting performance information.

As shown in fig. 4, specifically, in practical application, threshold values corresponding to different performance levels may be formulated according to the quality of performance, and then the performance characterization values on the visualized characterization image may be graded through a plurality of threshold values, so that the color gamut on the visualized characterization image is divided into a plurality of color gamut ranges, and the plurality of color gamut ranges respectively correspond to different performance levels. For example, the gamut range divided by the threshold value 1 in fig. 4 corresponds to a high performance level, the gamut range divided by the threshold value 2 corresponds to a medium performance level, and the gamut range divided by the threshold value 3 corresponds to a low performance level.

Further, in some embodiments, after the step of dividing the visual representation image into a plurality of color gamut ranges for different performance levels according to the grading threshold of the target ambient lighting performance information, the method further includes: calling color gamut range division results of other types of environment illumination performance information corresponding to the visual representation images; obtaining the overlapped color gamut ranges with the same performance level by combining the color gamut range division result corresponding to the target ambient lighting performance information and the color gamut range division result corresponding to other types of ambient lighting performance information; and referring to the overlapped color gamut range, and dividing the visual representation image corresponding to the target environment lighting performance information into a plurality of color gamut ranges.

Specifically, in practical applications, there may be a plurality of types of ambient lighting performance to be evaluated, and then there are a plurality of performance characterization results, and the color gamut ranges correspondingly divided according to the performance grading threshold are also different, as shown in fig. 5, another color gamut range division diagram provided in this embodiment is provided. In this embodiment, considering that the performance of one light source is optimized and the performance of another light source is rather impaired when performing light source control based on the color gamut range division result with only a single performance, in a specific practice, the color gamut range division results with multiple light source performances are integrated to obtain a common color gamut area (i.e. an overlapped color gamut range) with the same performance level in multiple aspects, and then further perform color gamut range division on the performance characterization image with a certain ambient lighting performance, for example, the performance characterization image shown on the display component currently is the performance characterization image of fig. 4, and the high performance level color gamut range of the performance characterization image is larger than and can completely cover the high performance level color gamut range of the performance characterization image of fig. 5, the high performance level color gamut range is modified with reference to the high performance level color gamut range divided by the threshold 1 in fig. 5, so that the high performance level threshold range finally divided on the performance characterization image of fig. 4 is the color gamut range with optimal multiple performances, when this gamut range is triggered by a user, a collaborative optimization of the multi-ambient lighting performance can be achieved.

Further, in some embodiments, before the step of dividing the visual representation image into a plurality of color gamut ranges for different performance levels according to the grading 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 the embodiment, it is considered that the lighting scene under the same lighting environment is dynamically changed, the lighting conditions are usually different along with time period change, seasonal change and climate change in the day, and accordingly, the performance requirements of the user on the brightness, color temperature, rhythm change and the like of the lighting environment are different, so that the grading threshold is determined in real time according to the lighting scene to ensure that the performance grading division on the performance visual representation image is more suitable for the actual use requirements, and further more accurate light source adjustment control is realized.

In another optional implementation manner of this embodiment, the step of performing corresponding visual representation on the target ambient lighting performance information according to the relative performance characteristic model and the chromaticity information, and the absolute performance characteristic model and the luminosity information and the chromaticity information in each independent color gamut on the chromaticity diagram includes: respectively determining performance evaluation values of independent color gamuts of different types of target environment illumination performance information on a chromaticity diagram according to the relative performance characteristic model and the chromaticity information, and the absolute performance characteristic model and the luminosity information and the chromaticity information; calculating the comprehensive performance evaluation value of each independent color gamut according to the evaluation values of the different types of target environment illumination performance information; and carrying out visual representation on the whole different types of target environment illumination performance information on each independent color gamut on the chromaticity diagram based on the comprehensive performance evaluation value.

In particular, unlike the previous embodiments in which the display assembly displays a visual representation of a single ambient lighting performance, the present embodiments implement a visual representation of a composite ambient lighting performance. In a specific practice, the comprehensive performance evaluation value of each color gamut of the chromaticity diagram is calculated based on different performance evaluation values, and a specific calculation implementation can be realized by adopting a weighting and averaging manner, and then when performing visual performance characterization, the comprehensive performance evaluation value is characterized on the chromaticity diagram. Therefore, when the color gamut is divided, the cooperative optimization of the multi-environment illumination performance can be realized in the light source adjustment control according to the performance level, namely the comprehensive performance level, corresponding to each color gamut divided by the classification threshold.

According to the light source control method provided by the embodiment of the invention, luminosity information and chrominance information corresponding to each spectral channel of a 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; performing corresponding visual representation on the lighting performance information of the target environment by each independent color gamut on a chromaticity diagram according to the relative performance characteristic model and the chromaticity information, and the absolute performance characteristic model and the luminosity information and the chromaticity information, and outputting a visual representation image through a display assembly; when a control instruction input aiming at a target color gamut range in the visual representation image is received, the corresponding luminosity information and the corresponding chromaticity information of the target color gamut range are referred to, and the corresponding spectrum channels of the multispectral light source are controlled to carry out light color adjustment. By implementing the method, the spectral characteristics of the light source are fully considered, the light source performance is visually represented based on the incidence relation between the chromaticity, the luminosity and the light source performance, the light source performance can be accurately evaluated, and effective guidance can be provided for the adjustment and control of the light source.
