Abstract

A low-pressure mercury vapour lamp is provided with a luminescent layer 4 which emits long-wave ultraviolet radiation and a reflecting layer 5 comprising aluminium oxide preferably of size 0.1 to 20 mu m, on part of the inside of the vessel. The luminescent layer 4 comprises a material activated by bivalent europium and having a fundamental strontium tetraborate lattice and is preferably defined by the formula Sr1-x-pMxEapB4O7. Where M=Ba, Ca or Mg 0</=x</=0.25 and 0.03</=p</=0.20 e.g Sr0.97E0.03B4O7. The layer 4 may extend round all or part of the inside of the vessel 1. A further layer of luminescent material e.g. Y2O3:Eu may be used. The output of the lamp is extended by the combination of luminescent and reflecting layers. <IMAGE>
