A color cover/change/mixture structure of a light bulb/tube/fixture includes an enclosure, a base, a cold cathode fluorescent lamp tube, and a color cover. The enclosure is a tubular body having a non-light-transmitting or light-transmitting top and a light-transmitting bottom. The base has a bottom surface having retention pawls for engaging and retaining the cold cathode fluorescent lamp tube. The cold cathode fluorescent lamp tube, after combined with the base, is disposed and mounted in the enclosure. Heads are mounted to two ends of the enclosure. The color covers have different colors and are selectively mounted to the enclosure to change the color of light emitting from the cold cathode fluorescent lamp tube.本創作係一種燈泡、燈管、燈具的套色變色混色結構,主要包含燈殼、基座、冷陰極燈管及色套等構件,該燈殼為頂部不透光或可透光而底部可透光的管體,於燈殼內兩側設有槽軌,該基座為一平板體,於底面設有勾爪用以將冷陰極燈管勾扣於底面上,於接合冷陰極燈管後置入燈殼內,讓板體兩邊置於燈殼內兩側的槽軌內,再於燈殼兩端套上燈頭而完成一燈管型的冷陰極燈管燈具,該色套為接近或略大於半圓形態的環型透光且具有彈性的長/短套體或是圓管型套筒式的環型透光且具有彈性的長/短套體,得利用單數或複數個不同顏色的色套套夾於燈殼底面或透光面上或用套筒式直接穿套,讓於室內分區栽種的蔬果,除了基本色燈管的光譜外,各色套可補個別需要的光譜顏色,使該燈具能產生多個區塊不同顏色或在極小的固定區塊內在單一光源上能同時提供幾個不同顏色的照射光,且讓栽種者可自己依經驗或參考農務書籍來決定套上何種顏色的色套;藉此結構之冷陰極燈管燈具用於室內植栽培養時,得有不同色調光譜的照射光對植栽物進行照射,以使植栽物能在生長成長的各階段能適時的在各階段補足各種光合作用所需的各色光譜,達到更好甚至最好的生長效能為其目的,此色套結構應用不限於只提供植物栽植照射用,且不限定在室內使用,凡需要調整光源達到變色及套色混色的應用場所均適用。10‧‧‧燈殼11‧‧‧燈頭101‧‧‧槽軌20‧‧‧基座21‧‧‧勾爪30‧‧‧冷陰極燈管31‧‧‧燈座301‧‧‧接頭40‧‧‧色套
