Problems solved by technology

But when it is necessary to accurately mix the color with the color coordinates of (0.3804, 0.3767) in a certain scene, even if the light adjuster adjusts it while measuring with the help of an instrument, it is difficult to achieve
The method of manually adjusting the brightness ratio of each primary color to achieve color mixing is inefficient and inaccurate
[0004] Secondly, the color mixing effect obtained by the dimmer based on experience matching only satisfies the color effect, but the result is often not the maximum brightness, and cannot maximize the use of the brightness resources of colored lamps

Abstract

The invention relates to the technical field of color lamp illumination, and in particular relates to an automatic maximum brightness color matching realizing method for a color lamp and a color modulation method and system. When the color lamp has three or more than three primary colors, multiple feasible solutions are provided for realizing a certain point in a color gamut space. According to the invention, the maximum brightness color matching algorithm is used to efficiently and accurately calculate the brightness formula of each primary color for the color lamp to realize the coordinate point of a certain color in the color gamut space; the brightness of the color lamp reaches the maximum after color matching; through the maximum brightness color matching algorithm, the brightness formula of a common target color in the color gamut space of the color lamp is calculated; the formulas are stored in a control unit of the lamp; a dimmer can easily call the desired color mixing formulaby adjusting a color matching channel on a console; automatic, fast and precise color mixing is realized with one button; and the maximum brightness is realized after color mixing, so that the brightness resources of the color lamp can be fully utilized.

Description

technical field [0001] The invention relates to the technical field of colored lamp lighting, in particular to a color matching method for automatically realizing maximum brightness of colored lamps, a color matching method and a system. Background technique [0002] With the continuous development of science and technology and the increasingly rich and colorful human living environment, people's demand for lighting and lighting colors is increasing. The most important thing is to need a variety of colorful environment atmosphere. In order to meet the diverse needs of people, colored lamps and their technologies continue to develop. Common colorful lights are obtained by mixing three colors of red (Red), green (Green), and blue (Blue). By mixing the three primary colors of RGB according to different proportions and strengths, various colors can be produced. In addition, there are colored lights with more primary colors, such as RGBW and so on. [0003] When dimming and mi...
