LOW-MERCURY-CONSUMING FLUORESCENT LAMPS WITH PHOSPHOR/ALUMINA-CONTAINING LAYER
摘要
A low-mercury-consuming fluorescent lamp (1) contains a fine particle size alpha alumina in the phosphor-containing layer (16) on the inner surface (15) of the lamp envelope (3). The lamp envelope (3) may have one or more bends (22), in which case the phosphor- containing layer (16) additionally contains an adhesive, such as a borate adhesive, to enhance adhesion, especially in the bend areas. The phosphor-containing layer (16) may be formed from a water-based coating suspension to which the fine particle alpha alumina is added after its pre-dispersion in deionized water.
