Fluorescent lamp having reflective layer |
摘要 |
A reflector fluorescent lamp with a reflective layer between the light-transmissive envelope and the phosphor layer(s). The reflective layer has a coating weight of at least 5, more preferably 6-8, mg/cm2 and is a blend of gamma alumina and alpha alumina, preferably 7-80 weight percent gamma alumina and 20-93 weight percent alpha alumina, more preferably 30-40 weight percent gamma alumina and 60-70 weight percent alpha alumina. The reflective layer finds particular utility in an electrodeless fluorescent lamp.
