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