Description
本發明有關於一種光調整裝置和混光照明系統,尤指一種漸進式離散平滑光調整裝置和漸進式離散平滑光混光照明系統。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.
三原色光模式(RGB color model),又稱RGB顏色模型或紅綠藍顏色模型,是一種加色模型,將紅(Red)、綠(Green)、藍(Blue)三原色的色光以不同的比例相加,以合成產生各種色彩光。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.
前述三原色的原理並非出於物理原因,而是人類生理原因所造成,由於人的眼睛內有幾種辨別顏色的錐形感光細胞,該錐形感光細胞根據刺激使人感覺到顏色,其中,該錐形感光細胞有三種,但這三種細胞並不是分別對紅色、綠色和藍色最敏感,只是這三種光可以分別對三種錐形細胞產生刺激。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.
依照上述,使用三原色並重現所有的色彩並不是完全正確的說法,準確地說應該是「將三原色光以不同的比例混合後,對人的眼睛可以形成與各種頻率的可見光等效的色覺。」只有那些在三原色的色度所定義的顏色三角內的顏色,才可以利用三原色的光以非負量相加混合得到。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.
混光的方式有一種為漸進式混光技術,藉由使用者設定期望的混光色,將RGB三色依據光階進行調整並混光後即為使用者需要的混光色,但混光時所使用的漸進式調整於輸出光時有可能會有偏差,而使輸出的混光色沒有達到預期的效果。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.
