Description

Progressive discrete smooth light adjusting device and progressive discrete smooth light mixed light illumination system

The invention relates to a light adjusting device and a light mixing lighting system, in particular to a progressive discrete smooth light adjusting device and a progressive discrete smooth light mixing lighting system.

The RGB color model, also known as the RGB color model or the red-green-blue color model, is an additive color model that compares the colors of the three primary colors of Red, Green, and Blue in different proportions. Add to synthesize to produce various colors of light.

The principle of the aforementioned three primary colors is not due to physical reasons, but human physiological reasons. Because there are several cone-shaped photoreceptor cells in the human eye that distinguish colors, the cone-shaped photoreceptor cells make people feel the color according to the stimulus. There are three types of cone photoreceptor cells, but these three types of cells are not the most sensitive to red, green, and blue respectively, but these three types of light can stimulate the three types of cone cells respectively.

According to the above, using the three primary colors and reproducing all colors is not completely correct. To be precise, it should be "After the three primary colors are mixed in different proportions, the human eye can form a color vision equivalent to visible light of various frequencies. "Only those colors within the color triangle defined by the chromaticity of the three primary colors can be obtained by non-negative addition and mixing of the light of the three primary colors.

One of the light mixing methods is the progressive mixing technology. By setting the desired light mixing color by the user, the RGB three colors are adjusted according to the light level and the light mixing becomes the light mixing color the user needs, but the light mixing The gradual adjustment used at this time may have deviations in the output light, and the output mixed light color does not achieve the expected effect.
