<p>Disclosed are a method for adjusting the target volume of a light source and the light source. The light source comprises three groups of luminous elements and each group comprises the luminous elements of at least one color; the three groups of luminous elements together comprise the luminous elements of at least four colors, and the luminous elements of the same color are located in the same group of luminous elements. The method comprises the steps of: obtaining target tristimulus values of the light source; obtaining tristimulus values of each group of luminous elements under the maximal luminous flux; considering each group of luminous elements as the luminous elements of one color, calculating the coefficient of adjustment for the luminous flux of each group of color luminous elements according to the target tristimulus values and the respective tristimulus values of the three groups of luminous elements, and normalizing the coefficient of adjustment; and adjusting the luminous fluxes of each group of luminous elements according to the coefficient of adjustment of this group of luminous elements. Therefore, the unique solution to the luminous fluxes of the color luminous elements in the light source with the luminous elements of at least four colors upon arrival at predetermined chromaticity coordinates is simply and readily attained.</p> |
