摘要：

Fluorescent lamps containing a two-component phosphor system consisting essentially of europium activated barium magnesium aluminate as a blue emitter and manganese and antimony activated calcium chlorofluorapatite as a yellow emitter use less energy to achieve at least comparable brightness as a standard cool white lamp with a suitable color rendering index.
