荧光灯大约消耗照明电能的30％,而所发出的光通量则为整个光源所产生的总光通量的60％。荧光灯的广泛应用与发展前景要求不断地提高它们的使用参数。稳定光通量和排除荧光灯两端的所谓“灰膜”的有效方法之一是涂一层保护层。为此不少作者报导了采用钾铝含氧硝酸盐用于此目的。用它作为无机水溶性胶粘剂来改善涂管时荧光粉层对玻璃管的附着力、作为放电管阴极用氧化 Fluorescent lamps consume about 30% of the electrical energy of the lighting, while the luminous flux emitted is 60% of the total luminous flux generated by the entire light source. The widespread application and development of fluorescent lamps requires that their use parameters be continuously improved. One of the effective ways to stabilize the luminous flux and eliminate the so-called “gray film” at both ends of the fluorescent lamp is to apply a protective coating. Many authors have reported the use of potassium aluminum oxynitrates for this purpose. Use it as an inorganic water-soluble adhesive to improve the adhesion of the phosphor layer to the glass tube during tube coating as cathode for discharge tube
