| 简介 |
A mercury vapor discharge fluorescent lamp (10) is provided having a single composite phosphor-containing layer (14). The composite layer (14) contains both a heterogeneous mixture of halophosphors (32), rare earth triphosphors (34) and colloidal alumina particles (36). The coating weight and relative proportion of halophosphors (32) to triphosphors (34) are both tunable to obtain a lamp having specific performance characteristics suitable to a particular application. The colloidal alumina particles (36) contained in the composite layer (14) eliminate the need for a separately applied alumina layer as is conventional in the prior art. |
