This creation system provides a kind of fluorescent tube variation structure (one), it is mainly characterized by one outer tube of cover on the general fluorescent tube of what, and what outer tube even tube wall is coated with the nanometer photocatalyst of one layer of light transmission, thereby, when what unlatching fluorescent tube carries out illumination use, light triggers the nanometer photocatalyst of outer tube simultaneously and carries out sterilization and deodorization to air to purify air, and it is larger by the caliber of what outer tube, therefore there is bigger contact area with air, and then greatly improves the effect of its sterilization and deodorization purification air.本創作係提供一種日光燈管變化結構(一)，其主要特點是於一般日光燈管上覆罩一外罩管，並於外罩管管壁均勻塗佈一層透光的奈米光觸媒，藉此，於開啟日光燈管進行照明使用時，燈光同時觸發外罩管的奈米光觸媒而對空氣進行殺菌及除臭以淨化空氣，且由於外罩管的管徑較大，因此與空氣具有更大的接觸面積，進而大幅提高其殺菌及除臭淨化空氣的效果。
