環(huán)保LED軟燈條組成資料不論是LED仍是FPC，其質料都是選用的環(huán)保質料，歸于可回收運用型，不會因為許多運用而構成對環(huán)境的污染和損壞。6.安全LED軟燈條選用的是低壓直流12V供電電壓，因此運用上十分安全。不論白叟、小孩都可以安全運用而不會引起安全隱患。7.簡易設備LED軟燈條設備十分簡潔，配用固定夾、線槽、鐵線、鐵網等即可設備在多種支承面上。其他，因為LED軟燈條輕、薄，因此，選用雙面膠也可以結束固定的功用。無需專業(yè)人員即可設備，可以真實享受DIY的裝飾愛好。8.壽數長LED軟燈條的正常運用壽數是8~10萬小時，每天24小時不斷的作業(yè)，其壽數都差不多近10年。因此，LED軟燈條的壽數是傳統(tǒng)燈具的好幾倍。9.使用范圍LED軟燈條因為柔軟、輕浮、色彩樸實等特征，被使用于樓體概括，臺階，展臺，橋梁，酒店，KTV裝飾照明，以及廣告招牌的制造、各種大型動畫、字畫的廣告設計等場所。跟著LED軟燈條技能的逐步老練，其使用范圍將愈加。上海先盛照明電器有限公司LED獲得眾多用戶的認可。</p><div
