Getter materials for the latter two are zircon, barium and hatriua. This · Obiter can be used both in old Oae filled as well as in vented lamps, la the last case, possibly in connection with phosphorus, apply "

Phosphorus is used very frequently in incandescent lamps · Gr becomes la The red modification is attached to a point in the lamp which, when the lamp is in operation, has a pre-draining temperature of red phosphorus above. assumes rising temperature. Generally the oil wire is used for this purpose elected. The evaporated phosphorus reacts with no oh sum Toil. in the Incandescent residual gases, such as oxygen, and accumulate in part in the form of the yellow modification on the flask wall. One by phosphorus However, the gold-colored incandescent lamp bulb cannot be brewed for practical purposes. The amount of phosphor to be introduced into the lamp therefore becomes such dimensioned so that almost no phosphorus can deposit on the piston wall * However, this means that, although in the flask, evaporation occurs immediately dea roton phosphorus no or almost no more roasting gases such as oxygen are present, which over the life of the lamp 2 · 3. from the piston » wall outgassed water vapor is either insufficiently bound or not bound at all.

Bio invention aims to create a light bulb in the except where appropriate, other getters for binding clay, reactive gases, such as oxygen, a getter is available which - of course, depends on of the length used and the length of time v> n during the life of the lamp released from the wall of the Kolbon and at the beginning of the operation of the lamp Water vapor - bind water vapor over the entire service life can"

This is achieved according to the invention with an incandescent lamp that as animals contains a metal phosphide that is already present at room temperature old water vapor reacts and attached to a stello in the lamp lsi, where the temperature is neither during the eyrie division nor when the

Lamp rises to or above a temperature at which the metal phosphide
