It should be understood that the embodiments described here are only used to explain the present invention, but not to limit the present invention.
如第1圖所示,提出了一種照明混光計算方法,該照明混光計算方法可以應用於電腦設備,該照明混光計算方法具體包括以下步驟: As shown in Figure 1, a method for calculating lighting mixing is proposed. The lighting mixing calculation method can be applied to computer equipment. The lighting mixing calculation method specifically includes the following steps:
步驟102,獲取第一色光對應的第一色座標點,獲取第二色光對應的第二色座標點。 Step 102: Acquire a first color coordinate point corresponding to the first color light, and acquire a second color coordinate point corresponding to the second color light.
其中,不同的色光對應的色座標點不同。如第2圖所示,為CIE 1931色座標圖。圖中,每個點相應的座標稱為“色座標點”。CIE1931是國際發光照明委員會建立的一套界定和測量色彩的技術標準。第一色光與第二色光不同,為了區分將第一色光的色座標點稱為“第一色座標點”,將第二色光的色座標點稱為“第二色座標點”。 Among them, the color coordinate points corresponding to different shades are different. As shown in Figure 2, it is a CIE 1931 color coordinate map. In the figure, the corresponding coordinates of each point are called "color coordinate points". CIE1931 is a set of technical standards for defining and measuring color established by the International Commission on Luminous Lighting. The first color light is different from the second color light. In order to distinguish the color coordinate point of the first color light as the "first color coordinate point", the color coordinate point of the second color light is called the "second color coordinate point".
色座標(chromaticity coordinate)係指顏色的座標,橫軸為x,縱軸為y,有了色座標,就可以在色度圖上唯一確定一個點,這個點精確地表示了 發光顏色。除了用x,y表示,更可以用色溫來表示照明光源的發光顏色。在一個實施方式中,第一色光為暖白光(Warm White)、第二色光為冷白光(Cool White)。第一色座標點、第二色座標點的確定可以藉由查找發出相應色光的LED光源所對應的出廠規格書中得到,為了更準確,也可以藉由測量設備(比如,積分球)實際測量得到。 The chromaticity coordinate refers to the coordinate of the color. The horizontal axis is x and the vertical axis is y. With the color coordinate, you can uniquely determine a point on the chromaticity diagram, and this point accurately represents Luminous color. In addition to expressing with x and y, color temperature can also be used to express the luminous color of the lighting source. In one embodiment, the first color light is Warm White and the second color light is Cool White. The determination of the first color coordinate point and the second color coordinate point can be obtained by searching the factory specifications corresponding to the LED light source emitting the corresponding color light. In order to be more accurate, it can also be measured by measuring equipment (for example, integrating sphere). get.
步驟104,獲取目標色座標點,根據目標色座標點、第一色座標點和第二色座標點計算得到第一色光和第二色光的第一流明值混合比例。 Step 104: Obtain the target color coordinate point, and calculate the first lumen value mixing ratio of the first color light and the second color light according to the target color coordinate point, the first color coordinate point and the second color coordinate point.
其中,目標色座標點係指混光所要得到的目標色光所對應的座標點。目標色座標點可以根據實際需要自定義設置。比如,為了減少色容差,將目標色座標點定義為Energy Star上的點,當然也可以定義為普朗克軌跡黑體曲線上的點以及自定義的任意點。在確定了目標色座標點後,就可以根據混色原理計算得到第一色光和第二色光的混合比例,混合比例實質上是流明值的混合比例,為了與後續出現的混合比例進行區分,稱為“第一流明值混合比例”。流明值就是光通量,因為光通量的單位是lm(流明),所以光通量也稱為“流明值”。 Among them, the target color coordinate point refers to the coordinate point corresponding to the target color light to be obtained by mixing. The target color coordinate points can be customized according to actual needs. For example, in order to reduce the color tolerance, the target color coordinate point is defined as a point on the Energy Star. Of course, it can also be defined as a point on the Blackbody curve of the Planckian locus and a custom point. After the target color coordinate point is determined, the mixing ratio of the first color light and the second color light can be calculated according to the color mixing principle. The mixing ratio is essentially the mixing ratio of the lumens value. In order to distinguish it from the subsequent mixing ratio, it is called It is the "first lumen value mixing ratio". Luminous value is luminous flux, because the unit of luminous flux is lm (lumens), so luminous flux is also called "lumen value".
在一個實施方式中,顏色混合的數學理論中的三刺激值可以寫成如下的形式:X=x*(Y/y);Y=Y;Z=(Y/y)*(1-x-y) In one embodiment, the tristimulus value in the mathematical theory of color mixing can be written as follows: X=x*(Y/y); Y=Y; Z=(Y/y)*(1-x-y)
公式中的x,y分別為色座標點的橫坐標和縱坐標,X、Y和Z分別為三刺激值。最後混合得到的顏色取決於三刺激值的數值,下面係以兩色光混合為例:Xmix=X1+X2;Ymix=Y1+Y2;Zmix=Z1+Z2 In the formula, x, y are the abscissa and ordinate of the color coordinate point, and X, Y, and Z are the tristimulus values. The final mixed color depends on the value of the tristimulus value. The following is an example of two-color light mixing: Xmix=X1+X2; Ymix=Y1+Y2; Zmix=Z1+Z2
那麼混合得到的,xmix=Xmix/(Xmix+Ymix+Zmix) Then mixed, xmix=Xmix/(Xmix+Ymix+Zmix)
ymix=Ymix/(Xmix+Ymix+Zmix) ymix=Ymix/(Xmix+Ymix+Zmix)
Φmix=Ymix。 Φmix=Ymix.
其中,X1、Y1和Z1為第一色光對應的三刺激值,X2、Y2和Z2為第二色光對應的三刺激值。xmix、ymix為混合得到的色座標點,即中間色座標點的x值和y值。Φmix為混合得到的光通量(即流明值)。所以在已知目標色座標點、第一色座標點和第二色座標點的情況下,就可以計算得到第一色光和第二色光的混合比例。 Among them, X1, Y1, and Z1 are the tristimulus values corresponding to the first color light, and X2, Y2, and Z2 are the tristimulus values corresponding to the second color light. xmix and ymix are the color coordinate points obtained by mixing, that is, the x value and y value of the intermediate color coordinate point. Φmix is the luminous flux obtained by mixing (ie, lumen value). Therefore, when the target color coordinate point, the first color coordinate point and the second color coordinate point are known, the mixing ratio of the first color light and the second color light can be calculated.
在一個實施方式中,第一色光可以選用暖白光(比如,色溫為2700K的色光),第二色光可以選用冷白光(比如,色溫為6500K的色光)。第3A圖為一個實施方式中暖白光和冷白光進行混合的示意圖,如第3A圖所示,兩色混光得到的中間色光只能在兩點直線上(圖中叉號所在的直線),所以當目標色座標點在兩點直線外時,得到的第一流明值混合比例不能夠很精確,故導致後續進行混光得到的中間色光與目標色光會存在一定的色容差,如第3B圖為混合得到的不同色溫對應的混合比例的示意圖,即不同的混合比例,得到的混合座標點不同,圖中的橫坐標係用色溫來表示的,不同的色溫對應的色座標點不同。 In one embodiment, the first color light may be warm white light (for example, a color light with a color temperature of 2700K), and the second color light may be cold white light (for example, a color light with a color temperature of 6500K). Figure 3A is a schematic diagram of the mixing of warm white light and cool white light in an embodiment. As shown in Figure 3A, the intermediate color light obtained by mixing two colors can only be on a straight line with two points (the line where the cross in the figure is). Therefore, when the target color coordinate point is outside the two-point straight line, the obtained first lumen value mixing ratio cannot be very accurate, so that the intermediate color light obtained by subsequent mixing and the target color light will have a certain color tolerance, such as 3B The figure is a schematic diagram of the mixing ratios corresponding to different color temperatures obtained by mixing, that is, different mixing ratios result in different mixing coordinate points. The abscissa system in the figure is represented by color temperature, and different color temperatures correspond to different color coordinate points.
步驟106,確定根據第一流明值混合比例混合第一色光和第二色光得到的中間色光對應的中間色座標點。 Step 106: Determine an intermediate color coordinate point corresponding to the intermediate color light obtained by mixing the first color light and the second color light according to the first lumen value mixing ratio.
其中,中間色座標點係指藉由將第一色光和第二色光按照”第一流明值混合比例”混合得到的中間色光所對應的色座標點。由於兩色混光得到的 中間色光只能在兩點直線上,如果目標色座標點不在兩點直線上,那麼得到的中間色光的中間色座標點與目標色座標點會有一定的偏差,所以需要單獨來計算中間色光對應的中間色座標點。 Among them, the intermediate color coordinate point refers to the color coordinate point corresponding to the intermediate color light obtained by mixing the first color light and the second color light according to the "first lumen value mixing ratio". Due to the two-color mixing The intermediate color light can only be on the two-point straight line. If the target color coordinate point is not on the two-point straight line, then the intermediate color coordinate point of the obtained intermediate color light will have a certain deviation from the target color coordinate point, so it is necessary to calculate the corresponding intermediate color light separately Intermediate color coordinate point.
步驟108,根據中間色座標點確定與中間色座標點匹配的第一補償色光和第二補償色光。 Step 108: Determine the first compensation color light and the second compensation color light matching the middle color coordinate point according to the middle color coordinate point.
其中,在得到了中間色光對應的中間色座標點後,為了減少色容差,需要對中間色光進行補償,使之補償為目標色光。根據中間色光的中間色座標點來選取與該中間色座標點匹配的第一補償色光和第二補償色光。第一補償色光和第二補償色光可以選用紅、綠、藍等基礎色光,當然也可以選用其他色光,只要選用的第一補償色光、第二補償色光、以及第一色光和第二色光所確定的色域範圍內包含有目標色座標點和中間色座標點,就可以混合到目標色光。在一個實施方式中,根據中間色座標點與目標色座標點的位置關係從紅、綠、藍三個基礎色光中選取兩個色光分別作為第一補償色光和第二補償色光。 Among them, after obtaining the intermediate color coordinate points corresponding to the intermediate color light, in order to reduce the color tolerance, it is necessary to compensate the intermediate color light to make it the target color light. According to the intermediate color coordinate point of the intermediate color light, the first compensation color light and the second compensation color light that match the intermediate color coordinate point are selected. The first compensation color light and the second compensation color light can be red, green, blue and other basic color lights. Of course, other color lights can also be selected. As long as the first compensation color light, the second compensation color light, and the first color light and the second color light are selected The determined color gamut includes the target color coordinate point and the intermediate color coordinate point, which can be mixed to the target color light. In one embodiment, according to the positional relationship between the intermediate color coordinate point and the target color coordinate point, two color lights are selected from the three basic color lights of red, green and blue as the first compensation color light and the second compensation color light respectively.
步驟110,根據第一補償色光和第二補償色光對中間色光進行補償計算,確定混合到目標色座標點時第一補償色光、第二補償色光和中間色光所對應的第二流明值混合比例。 Step 110: Perform a compensation calculation on the intermediate color light according to the first compensation color light and the second compensation color light, and determine the second lumen value mixing ratio corresponding to the first compensation color light, the second compensation color light and the intermediate color light when mixed to the target color coordinate point.
其中,在確定了第一補償色光、第二補償色光後,獲取第一補償色光對應的第一補償色座標點,第二補償色光對應的第二補償色座標點,根據第一補償色座標點、第二補償色座標點和中間色座標點計算得到要混合到目標色座標點時第一補償色光、第二補償色光和中間色光所對應的混合比例,即第二流明值混合比例。根據第二流明值混合比例混合第一補償色光、第二補償色光和中間色光就能夠混合得到與目標色座標點對應的目標色光,該混合得到的 目標色光的色容差能夠降低到1SCDM內,人眼感受不到色容差的存在,大大提高了混光的效果。 Among them, after determining the first compensation color light and the second compensation color light, the first compensation color coordinate point corresponding to the first compensation color light is obtained, and the second compensation color coordinate point corresponding to the second compensation color light is obtained according to the first compensation color coordinate point , The second compensation color coordinate point and the intermediate color coordinate point are calculated to obtain the mixing ratio corresponding to the first compensation color light, the second compensation color light and the intermediate color light when it is mixed to the target color coordinate point, that is, the second lumen value mixing ratio. According to the mixing ratio of the second lumen value, the first compensation color light, the second compensation color light and the intermediate color light can be mixed to obtain the target color light corresponding to the target color coordinate point. The color tolerance of the target color light can be reduced to within 1SCDM, and the human eye cannot feel the existence of the color tolerance, which greatly improves the effect of light mixing.
上述照明混光計算方法,首先,根據目標色座標點確定第一色光和第二色光的第一流明值混合比例,然後藉由混合第一色光和第二色光得到中間色光,由於中間色光存在較大色容差,所以繼續根據中間色座標點匹配到了第一補償色光和第二補償色光,然後對所述中間色光進行補償計算,確定混合到所述目標色座標點時所述第一補償色光、第二補償色光和所述中間色光所對應的第二流明值混合比例。根據第一流明值混合比例和第二流明值混合比例將第一色光、第二色光、第一補償色光和第二補償色光進行混合就可以完全混到目標色座標點,大大降低了色容差,提高了混光效果。 In the above-mentioned lighting mixing calculation method, first, the first lumen value mixing ratio of the first color light and the second color light is determined according to the target color coordinate point, and then the intermediate color light is obtained by mixing the first color light and the second color light. There is a large color tolerance, so continue to match the first compensation color light and the second compensation color light according to the intermediate color coordinate point, and then perform the compensation calculation on the intermediate color light, and determine the first compensation when mixed to the target color coordinate point The color light, the second compensation color light and the second lumen value mixing ratio corresponding to the intermediate color light. Mixing the first color light, the second color light, the first compensation color light and the second compensation color light according to the first lumen value mixing ratio and the second lumen value mixing ratio can completely mix to the target color coordinate point, greatly reducing the color volume Poor, improve the light mixing effect.
在一個實施方式中,所述根據所述中間色座標點確定與所述中間色座標點匹配的第一補償色光和第二補償色光,包括:獲取第三色光對應的第三色座標點、第四色光對應的第四色座標點和第五色光對應的第五色座標點;根據所述第三色座標點、第四色座標點、第五色座標點和所述中間色座標點確定所述目標色座標點所在的色域範圍;根據所述色域範圍從所述第三色光、第四色光、第五色光中選取出兩個色光作為第一補償色光和第二補償色光。 In one embodiment, the determining the first compensation color light and the second compensation color light that match the intermediate color coordinate point according to the intermediate color coordinate point includes: acquiring the third color coordinate point and the fourth color light corresponding to the third color light The corresponding fourth color coordinate point and the fifth color coordinate point corresponding to the fifth color light; the target is determined according to the third color coordinate point, the fourth color coordinate point, the fifth color coordinate point and the intermediate color coordinate point The color gamut range where the color coordinate point is located; according to the color gamut range, two color lights are selected from the third color light, the fourth color light, and the fifth color light as the first compensation color light and the second compensation color light.
其中,第三色光、第四色光、第五色光構成了一個大的色域區域,中間色座標點落入該大的色域區域內,目標色座標點也落入該大的色域區域內,為了對中間色光進行補償得到目標色光,首先需要確定目標色光具體是落入了哪個小的色域範圍內,根據第三色光、第四色光、第五色光和中間色光對應的色座標點將大的色域區域分為了三個小的色域範圍,在一個實施方式中,劃分為三個小的色域範圍的示意圖,如第4圖所示,三個小的色域範圍分別為三 角形RBM,三角形RGM和三角形BGM。為了對中間色光進行補償得到目標色光,需要確定目標色光具體落入了哪個小的色域範圍,然後根據該色域範圍從三個色光中選取兩個色光作為第一補償色光和第二補償色光。比如,假設落入了圖中RBM範圍內,那麼選取R和B分別作為第一補償色光和第二補償色光。 Among them, the third color light, the fourth color light, and the fifth color light constitute a large color gamut area, the intermediate color coordinate point falls within the large color gamut area, and the target color coordinate point also falls within the large color gamut area. In order to compensate the intermediate color light to obtain the target color light, it is first necessary to determine which small color gamut the target color light falls into. According to the color coordinate points corresponding to the third color light, the fourth color light, the fifth color light and the intermediate color light, The large color gamut area is divided into three small color gamut ranges. In one embodiment, it is a schematic diagram of three small color gamut ranges. As shown in Figure 4, the three small color gamut ranges are three Angular RBM, triangular RGM and triangular BGM. In order to compensate the intermediate color light to obtain the target color light, it is necessary to determine which small color gamut the target color light falls into, and then select two color lights from the three color lights as the first compensation color light and the second compensation color light according to the color gamut range . For example, if it falls within the RBM range in the figure, then R and B are selected as the first compensation color light and the second compensation color light, respectively.

其中,為了計算目標色座標點對應的色域範圍,分別計算第三色座標點、第四色座標點、第五色座標點、所述中間色座標點和目標色座標點中的任意三點組成的三角形的面積,從5個點中任意選出3個組成三角形,藉由排列組合可以得到10個三角形,即分別計算這10個三角形的面積。 Among them, in order to calculate the color gamut range corresponding to the target color coordinate point, the third color coordinate point, the fourth color coordinate point, the fifth color coordinate point, the intermediate color coordinate point and the target color coordinate point are calculated separately. For the area of the triangle, choose 3 out of 5 points to form a triangle, and you can get 10 triangles by permutation and combination, that is, calculate the area of these 10 triangles separately.
在一個實施方式中,第三色光、第四色光和第五色光分別為紅R、綠G、藍B三個基本色光。參考第4圖所示,E表示目標色光的目標色座標點,M表示混合得到的中間色光的中間色座標點。假設E落入三角形BGM中,那麼必然能夠得到:三角形BEG面積+三角形GEM面積+三角形BEM面積=三角形BGM面積。所以根據計算得到的各個三角形面積之間的關係就能夠得到與目標色座標點匹配的目標三角形面積。將該目標三角形面積作為目標色座標點對應的色域範圍。 In one embodiment, the third color light, the fourth color light, and the fifth color light are three basic colors of red R, green G, and blue B, respectively. Referring to Fig. 4, E represents the target color coordinate point of the target color light, and M represents the intermediate color coordinate point of the intermediate color light obtained by mixing. Assuming that E falls into the triangular BGM, then it must be obtained: triangular BEG area + triangular GEM area + triangular BEM area = triangular BGM area. Therefore, the target triangle area matching the target color coordinate point can be obtained according to the relationship between the calculated areas of the triangles. The target triangle area is taken as the color gamut range corresponding to the target color coordinate point.
在一個實施方式中,所述根據所述第一補償色光和所述第二補償色光對所述中間色光進行補償計算,確定混合到所述目標色座標點時所述第一補償色光、第二補償色光和所述中間色光所對應的第二流明值混合比例,包括:獲取所述第一補償色光的第一補償色座標點,獲取所述第二補償色光的第二補償色座標點;根據所述第一補償色座標點、第二補償色座標點和所述中間色座標點確定混合到所述目標色座標點時所述第一補償色光、第二補償色光和所述中間色光所對應的第二流明值混合比例。 In one embodiment, the compensation calculation is performed on the intermediate color light according to the first compensation color light and the second compensation color light, and it is determined that the first compensation color light and the second compensation color light are mixed to the target color coordinate point. The mixing ratio of the second lumen value corresponding to the compensation color light and the intermediate color light includes: obtaining a first compensation color coordinate point of the first compensation color light, and obtaining a second compensation color coordinate point of the second compensation color light; When the first compensation color coordinate point, the second compensation color coordinate point, and the intermediate color coordinate point are determined to be mixed to the target color coordinate point, the first compensation color light, the second compensation color light, and the intermediate color light correspond to The second lumen mixing ratio.
其中,在確定了第一補償色光和第二補償色光後,分別獲取第一補償色光對應的第一補償色座標點,獲取第二補償色光對應的第二補償色座標點,然後藉由將目標色座標點作為目標點,將第一補償色光、第二補償色光、中間色光作為已知座標的色光,然後藉由計算可以得到第一補償色光、第二補償色光和所述中間色光的第二流明值混合比例。只要根據該第二流明值混合比例進行混光就可以得到與目標色座標點對應的目標色光。 Among them, after determining the first compensation color light and the second compensation color light, the first compensation color coordinate points corresponding to the first compensation color light are obtained respectively, and the second compensation color coordinate points corresponding to the second compensation color light are obtained, and then the target The color coordinate point is used as the target point, and the first compensation color light, the second compensation color light, and the intermediate color light are used as the color lights of the known coordinates. Then, the first compensation color light, the second compensation color light and the second color light of the intermediate color light can be obtained by calculation. Lumen mixing ratio. As long as the light is mixed according to the second lumen value mixing ratio, the target color light corresponding to the target color coordinate point can be obtained.
在一個實施方式中,上述照明混光計算方法更包括:獲取所述目標色座標點對應的色溫,獲取所述目標色光對應的第一色光、第二色光、第一補償色光、第二補償色光之間的混合比例;將所述色溫與相應的所述混合比例進行關聯儲存。 In one embodiment, the above-mentioned lighting mixing calculation method further includes: acquiring the color temperature corresponding to the target color coordinate point, and acquiring the first color light, the second color light, the first compensation color light, and the second compensation color light corresponding to the target color light. The mixing ratio between the color lights; storing the color temperature and the corresponding mixing ratio in association.
其中,在得到目標色座標點後,獲取與該目標色座標點對應的色溫,然後獲取與目標色光對應的第一色光、第二色光、第一補償色光、第二補償色光之間的混合比例。即根據第一流明值混合比例和第二流明值混合比例可以計算得到最終第一色光、第二色光、第一補償色光、第二補償色光之間的混合比例。將該色溫與相應的混合比例進行關聯儲存。當後續需要獲取與該色溫 對應的目標色光時,獲取與色溫對應的混合比例,然後將第一色光、第二色光、第一補償色光、第二補償色光按照混合比例進行混合,以便於得到與該色溫對應的目標色光。 Among them, after obtaining the target color coordinate point, obtain the color temperature corresponding to the target color coordinate point, and then obtain the mixture of the first color light, the second color light, the first compensation color light, and the second compensation color light corresponding to the target color light proportion. That is, according to the first lumen value mixing ratio and the second lumen value mixing ratio, the final mixing ratio among the first color light, the second color light, the first compensation color light, and the second compensation color light can be calculated. Store the color temperature in association with the corresponding mixing ratio. When the subsequent need to obtain the color temperature When corresponding to the target color light, obtain the mixing ratio corresponding to the color temperature, and then mix the first color light, the second color light, the first compensation color light, and the second compensation color light according to the mixing ratio, so as to obtain the target color light corresponding to the color temperature .
在一個實施方式中,上述照明混光計算方法更包括:根據預設的條件確定當前照明對應的目標色溫,根據所述色溫與所述混合比例之間的對應關係,確定與所述目標色溫對應的目標混合比例;根據所述目標混合比例混合所述第一色光、第二色光、第一補償色光、第二補償色光,得到與所述目標色溫對應的目標色光。 In one embodiment, the above-mentioned lighting mixing calculation method further includes: determining a target color temperature corresponding to the current lighting according to a preset condition, and determining a color temperature corresponding to the target color temperature according to the corresponding relationship between the color temperature and the mixing ratio. The target mixing ratio of; mixing the first color light, the second color light, the first compensation color light, and the second compensation color light according to the target mixing ratio to obtain the target color light corresponding to the target color temperature.
其中,在一個照明應用場景中,為了使得照明的光能夠隨著時間變化,或者隨著外面光照強度來自動調節,需要即時確定與當前照明對應的色溫。舉個例子,假設為了使得照明的光能夠隨著時間變化,比如,設置早上8-9點的色溫為2700K,9點-10點的色溫為3000K等,那麼當獲取到當前時間後,就可以確定當前照明對應的目標色溫。然後就可以根據預存的色溫與混合比例的對應關係來確定與目標色溫對應的目標混合比例,然後根據目標混合比例混合第一色光、第二色光、第一補償色光、第二補償色光,得到相應的目標色光。 Among them, in a lighting application scene, in order to enable the light of the lighting to change over time, or to automatically adjust with the outside light intensity, it is necessary to determine the color temperature corresponding to the current lighting immediately. For example, suppose that in order to make the light of the illumination change over time, for example, set the color temperature of 8-9 o'clock in the morning to 2700K, and the color temperature of 9-10 o'clock to 3000K, etc., then when the current time is obtained, you can Determine the target color temperature corresponding to the current lighting. Then, the target mixing ratio corresponding to the target color temperature can be determined according to the corresponding relationship between the prestored color temperature and the mixing ratio, and then the first color light, the second color light, the first compensation color light, and the second compensation color light can be mixed according to the target mixing ratio.

在一個實施方式中,所述確定根據所述第一流明值混合比例混合所述第一色光和第二色光得到的中間色光對應的中間色座標點,包括:獲取目標流明值,根據所述目標流明值和所述第一流明值混合比例確定所述第一色光對應的第一流明值和所述第二色光對應的第二流明值;根據所述第一流明值和所述第二流明值確定混合所述第一色光和所述第二色光得到中間色光所對應的中間色座標點。 In one embodiment, the determining the intermediate color coordinate point corresponding to the intermediate color light obtained by mixing the first color light and the second color light according to the first lumen value mixing ratio includes: obtaining a target lumen value, and according to the target The mixing ratio of the lumen value and the first lumen value determines the first lumen value corresponding to the first color light and the second lumen value corresponding to the second color light; according to the first lumen value and the second lumen value The value determines the intermediate color coordinate point corresponding to the intermediate color light by mixing the first color light and the second color light.
其中,獲取設定的目標流明值,在已知第一流明值混合比例的情況下,就可以確定第一色光對應的流明值和第二色光對應的流明值,然後進行混合,就可以得到中間色光。由於根據第一色座標點、第二色座標點以及目標色座標點只能計算得到第一色光和第二色光的流明值比例,那麼給定目標流明值後,才能計算得到第一色光和第二色光具體的流明值,然後可以計算得到該第一流明值和第二流明值計算混合得到的中間色光對應的中間色座標點。 Among them, the set target lumen value is obtained, and when the mixing ratio of the first lumen value is known, the lumen value corresponding to the first color light and the lumen value corresponding to the second color light can be determined, and then mixed to obtain the intermediate color Light. Since only the ratio of the lumen value of the first color light and the second color light can be calculated according to the first color coordinate point, the second color coordinate point and the target color coordinate point, the first color light can be calculated after the target lumen value is given And the specific lumen value of the second color light, and then the intermediate color coordinate point corresponding to the intermediate color light obtained by calculating and mixing the first lumen value and the second lumen value can be calculated.
在一個實施方式中,藉由上述照明混光計算方法計算得到第一流明值混合比例和第二流明值混合比例,根據第一流明值混合比例和第二流明值混合比例就可以得到第一色光、第二色光、第一補償色光和第二補償色光所對應的混合比例,根據該混合比例來指導實際的混光能夠大大減少得到的目標色光的色容差。 In one embodiment, the first lumen value mixing ratio and the second lumen value mixing ratio are calculated by the above-mentioned lighting mixing calculation method, and the first color can be obtained according to the first lumen value mixing ratio and the second lumen value mixing ratio. The mixing ratios corresponding to the light, the second color light, the first compensation color light, and the second compensation color light, and guiding the actual light mixing according to the mixing ratio can greatly reduce the color tolerance of the obtained target color light.

其中,△x為x1值相對於目標值的誤差,△y為y1值相對於目標值的誤差。g11、g12和g22係由標準顏色確定的係數。 Wherein, △ x value x1 error relative to the target value, △ y is the value of y1 with respect to the target value of the error. g11, g12 and g22 are coefficients determined by standard colors.
如第6圖所示,為一個實施方式中,採用2色光和5色光(實際採用的是4色光,第一補償色光和第二補償色光係根據需要從3個基本色光(紅、綠、藍)中選取出的2個)進行混合的理論對比以及實際藉由積分球測量出來的結果對比示意圖。 As shown in Figure 6, it is an embodiment in which two-color light and five-color light are used (actually, four-color light is used. The first compensation color light and the second compensation color light system are selected from three basic colors (red, green, blue) as needed. The 2 selected in )) is a schematic diagram of the theoretical comparison of the mixing and the comparison of the actual results measured by the integrating sphere.
上述照明混光計算方法能夠準確地計算得到4個色光(第一色光、第二色光、第一補償色光、第二補償色光)的混合比例,根據計算得到的混合比例在實際應用中進行混色得到的目標色光的色容差小於1SCDM,大大降低了色容差,提高了混色的效果。該照明混光計算方法具有普適性,適用於任何照明產品。 The above-mentioned lighting mixing calculation method can accurately calculate the mixing ratio of the 4 color lights (the first color light, the second color light, the first compensation color light, and the second compensation color light), and perform the color mixing in actual applications according to the calculated mixing ratio The color tolerance of the obtained target color light is less than 1SCDM, which greatly reduces the color tolerance and improves the color mixing effect.
